How Crowdfolio Calculates Capital Gains Tax for ASX Trades

Understanding Capital Gains Tax Calculation for ASX Investors

Capital gains tax (CGT) is one of the most important tax considerations for Australian DIY investors trading on the ASX. Yet many investors only think about their tax liability when they lodge their tax return—by which time it’s too late to make tax-efficient decisions. This FAQ guide explains how Crowdfolio calculates CGT for ASX trades, helping you understand the mechanics behind tax-aware investing and how to forecast your tax outcomes before you trade. Many readers ask in plain terms how CGT calculated for common share sale scenarios, and this guide answers that directly. If you want a quick primer on how CGT calculated for simple trades and complex parcel mixes, read the sections below.

The Fundamentals: What Is Capital Gains Tax?

Q: What exactly is capital gains tax (CGT) in Australia?

Capital gains tax is a tax on the profit you make when you sell an asset at a higher price than you bought it. In Australia, CGT is not a separate tax; instead, the capital gain is added to your assessable income for the financial year and taxed at your marginal tax rate. According to the Australian Taxation Office’s official guidance on calculating your CGT, a capital gain is calculated by subtracting the cost base of the asset from the proceeds of sale, then applying any applicable discount or indexation. For most Australian share investors, this means your CGT liability depends on your income level, how long you held the shares, and the profit (or loss) you made. To help you understand the process in plain language, we explain how CGT calculated step‑by‑step for each parcel you hold. Knowing how CGT calculated for short-term versus long-term holdings is critical to deciding when to sell.

Q: Do I pay CGT on every share sale?

Yes, you pay CGT on every share sale where you make a profit. However, if you make a loss on a sale, that loss can be used to offset capital gains from other sales in the same financial year or carried forward to future years. The key is that CGT applies to each individual disposal event—which is why understanding parcel-level outcomes (which specific shares you’re selling) matters so much for tax planning. Many DIY investors ask specifically how CGT calculated when you make multiple partial disposals of the same holding, and the answer depends on your lot-selection method. Crowdfolio makes it easy to see exactly how CGT calculated for each disposal event so you can plan ahead.

Q: Why should I forecast my CGT before I trade?

Most investors only calculate their CGT at tax time, after all trades are done. By then, the damage is done. Crowdfolio puts the tax cost inside the trading decision by forecasting your CGT outcome before you rebalance or sell. This allows you to choose which parcels to sell (using FIFO, LIFO, specific, or highest-cost-first methods) to minimize your tax liability while still achieving your investment goals. Forecasting also helps you identify tax-loss harvesting opportunities and avoid wash-sale risks before they occur. When you use parcel-level forecasts you can see how CGT calculated in each hypothetical sale scenario and pick the most tax-efficient option.

How CGT Is Calculated: The Core Formula

Q: What is the basic formula for calculating capital gains tax on shares?

The fundamental CGT calculation is straightforward: Capital Gain = Sale Proceeds − Cost Base. The sale proceeds are the total amount you receive from selling the shares (minus any transaction costs like brokerage fees). The cost base is the total amount you paid to acquire the shares, plus any incidental costs of acquisition such as brokerage, stamp duty, or advisor fees. Once you have the capital gain, you apply the CGT discount (if eligible) and add the result to your assessable income. CommSec’s educational guide to Australian capital gains tax provides a worked example showing this calculation in action. If you need a quick checklist to remember how CGT calculated for a sale, it is: determine proceeds, compute cost base including fees, calculate gain or loss, then apply discounts. Crowdfolio automates all of these steps so you can see exactly how CGT calculated for each potential trade.

Q: What is the CGT discount, and who qualifies for it?

The CGT discount (also called the capital gains tax discount) is a significant tax concession available to Australian residents. If you held the asset for at least 12 months, you can discount the capital gain by 50% (for individuals). This means only 50% of the capital gain is added to your assessable income. For example, if you made a $1,000 capital gain on shares held for over 12 months, only $500 is added to your taxable income. Trusts and companies have different rules—trusts can access a 50% discount if certain conditions are met, while companies do not qualify for the discount at all. This is why the holding period is so critical: a 12-month hold can cut your tax bill in half. Many investors ask how CGT calculated when some parcels qualify for the discount and others do not; Crowdfolio flags discount eligibility and shows how CGT calculated across mixed parcels.

Q: What about indexation? Is that different from the CGT discount?

Indexation is an older tax concession that is no longer available to individuals but may still apply to some trusts and companies. Indexation adjusts the cost base of an asset for inflation, so you only pay tax on the real (inflation-adjusted) gain. Indexation is available only for assets acquired before 21 September 1999. An individual who still holds such an asset may choose indexation or the 50% discount, whichever gives the better result. For most DIY ASX investors (who are individuals), the CGT discount is what matters. If you’re comparing options, look at how CGT calculated under indexation rules versus the discount (where applicable) to pick the right approach for your entity type.

Parcel-Level Lot Selection: FIFO, LIFO, and Specific Identification

Q: What does “parcel-level” tax outcome mean, and why does it matter?

A parcel is a batch of shares acquired at a specific time and price. If you’ve bought the same share multiple times at different prices, you have multiple parcels. When you sell, the question is: which parcels are you selling? This matters enormously for tax because different parcels have different cost bases and holding periods. Selling the parcel with the highest cost base minimizes your capital gain (and tax), while selling the lowest-cost parcel maximizes your gain. Crowdfolio calculates parcel-level outcomes by showing you the exact tax impact of selling each possible parcel, so you can make informed decisions. Most brokers and portfolio trackers don’t show this level of detail—they assume a default method like FIFO—but Crowdfolio lets you preview the outcome before you trade. To answer the common user question: learn how CGT calculated at the parcel level and use that insight to reduce your tax liability.

Q: What is FIFO (First In, First Out) lot selection?

FIFO means selling your oldest parcels first. It is not a default the ATO imposes: Taxation Determination TD 33 puts the choice on you, and the Commissioner accepts first-in-first-out as a reasonable basis while equally accepting your own selection, provided your records support it. Under FIFO, when you sell shares, you’re assumed to be selling the oldest parcels first. So if you bought 100 shares in January at $10, then 100 shares in March at $15, and you sell 100 shares in June, you’re assumed to be selling the January parcel (cost base $10 per share). FIFO is simple and automatic, but it’s not always tax-efficient. If the oldest parcel has the lowest cost base, you’ll have a larger capital gain and higher tax. Finder’s explainer on capital gains tax for shares in Australia discusses how default lot selection methods affect your tax outcome. When evaluating FIFO, think about how CGT calculated under FIFO compared to alternatives like LIFO or specific identification.

Q: What is LIFO (Last In, First Out) lot selection, and when is it useful?

LIFO assumes you’re selling the most recent parcels first (the last ones you bought). Using the same example, if you sell 100 shares under LIFO, you’d be selling the March parcel (cost base $15 per share), which gives you a smaller capital gain ($0 if the price is $15) and lower tax. LIFO can be very tax-efficient in rising markets because newer parcels often have higher cost bases. There is no separate LIFO election to register. Selling your newest parcels is simply your own selection under TD 33, and it is the records you keep that evidence it. Crowdfolio allows you to preview LIFO outcomes before you trade, helping you decide if it’s worth the extra documentation. Many investors ask how CGT calculated under LIFO versus FIFO for the same sale; Crowdfolio shows that comparison instantly.

Q: What is specific lot selection, and how does it work?

Specific lot selection means you choose exactly which parcel (or parcels) to sell. This gives you maximum control and tax efficiency. For example, you might sell the parcel with the highest cost base to minimize your capital gain, or sell a parcel with a loss to offset gains elsewhere. Specific lot selection requires detailed records and clear communication with your broker, but it’s the most tax-efficient method for sophisticated investors. Canstar’s guide on capital gains tax for shares explains how different lot-selection methods affect your tax liability. Crowdfolio supports specific lot selection by letting you preview the exact tax outcome of selling any parcel before you commit. If you ever wonder how CGT calculated when you use specific identification, Crowdfolio’s parcel reports answer that precisely.

Q: What is the highest-cost-first method?

Highest-cost-first is a tax-optimization strategy where you deliberately sell the parcel with the highest cost base first. This minimizes your capital gain and tax in the current year. It’s similar to specific lot selection but with a clear rule: always pick the most expensive parcel. This method is particularly useful when you’re rebalancing and need to reduce a position. By selling the highest-cost parcel first, you keep the lower-cost parcels (which have larger unrealized gains) for future years, potentially allowing you to harvest losses later or time the sales more strategically. Crowdfolio’s parcel-level forecasting makes it easy to identify and execute highest-cost-first strategies. For those who like concrete comparisons, Crowdfolio shows how CGT calculated under highest-cost-first versus FIFO and LIFO.

Tax-Loss Harvesting and Offset Strategies

Q: What is tax-loss harvesting, and how can it reduce my CGT?

Tax-loss harvesting is the practice of deliberately selling shares at a loss to offset capital gains from other sales. For example, if you have a $5,000 gain from selling one share and a $2,000 loss from selling another, your net capital gain is $3,000 (taxed at your marginal rate, potentially with the 50% discount). Without the loss, you’d have paid tax on the full $5,000 gain. Tax-loss harvesting is a powerful tax-planning tool, especially near the end of the financial year. MoneyWiseCalc’s guide to capital gains tax on shares explains how losses offset gains in your tax calculation. Crowdfolio identifies tax-loss harvesting opportunities by showing you which parcels are underwater (trading below cost base) and the exact tax benefit of harvesting them. If you need help understanding how CGT calculated when applying harvested losses, Crowdfolio provides side‑by‑side before/after scenarios.

Q: What is a wash sale, and why does the ATO care about it?

A wash sale occurs when you sell shares at a loss to harvest the tax loss, then immediately buy substantially the same shares back. The ATO considers this a tax avoidance scheme and may disallow the loss under Part IVA (General Anti-Avoidance Rule). Australia has no codified wash-sale rule and no 30-day window: there is no waiting period that makes a repurchase safe, and none that makes it unsafe. TR 2008/1 states plainly that the term wash sale has no precise meaning, and the ATO’s example in TA 2008/7 catches a repurchase made 24 hours later. What matters is whether your economic exposure genuinely changed, and whether the dominant purpose was obtaining the tax benefit. Crowdfolio flags wash-sale risks by alerting you when a tax-loss harvest might trigger Part IVA concerns, citing the relevant ATO guidance so you can weigh it before you trade. That way you can see how CGT calculated if a loss is disallowed versus if it is accepted.

Q: Can I carry forward capital losses to future years?

Yes, capital losses can be carried forward indefinitely to offset capital gains in future years. However, capital losses cannot be used to offset other income (like salary or dividends)—they can only offset capital gains. If you make a net capital loss in a year, you can’t claim it as a deduction, but you can carry it forward to use against future gains. This is why maintaining detailed records of losses is important: you may need to prove the loss years later when you’re ready to use it. You enter your prior-year carried-forward losses in your account settings, and Crowdfolio applies them to the projected CGT so you can see what remains after offsets, making it easier to plan multi-year tax strategies and to understand how CGT calculated across years.

How Crowdfolio Forecasts Your CGT Before You Trade

Q: How does Crowdfolio calculate CGT without requiring broker logins?

Crowdfolio uses a privacy-first approach: instead of connecting to your broker, you upload a CSV export of your trades and holdings. This export contains all the information needed to calculate CGT—purchase dates, prices, quantities, and sale details. Crowdfolio then processes this data on Crowdfolio’s servers, without ever asking for your broker credentials, and calculates your CGT outcomes. There are templates for SelfWealth, Stake and CMC Markets, plus a generic template and an opening-balances template for any other broker. By avoiding broker logins, Crowdfolio also ensures you maintain full control and visibility over your data. The core question investors ask is how CGT calculated from a CSV feed—Crowdfolio reconstructs parcel histories so you can see the answer instantly.

Q: What information does Crowdfolio need to forecast CGT?

Crowdfolio needs your complete trade history: for each purchase, the date, quantity, price, and any transaction costs; for each sale, the date, quantity, sale price, and transaction costs. It also needs your current holdings and the current price of each holding (to forecast unrealized gains). With this information, Crowdfolio can calculate your cost base for each parcel, determine your holding periods, and forecast the CGT outcome of selling any combination of parcels. The more complete and accurate your data, the more accurate the forecast. CGT Strategist’s blog on calculating capital gains tax on shares and ETFs in Australia explains the importance of detailed trade records for accurate CGT calculations. If you’re wondering how CGT calculated for complex multi-broker portfolios, Crowdfolio merges multiple CSVs and shows the consolidated result.

Q: Can Crowdfolio forecast CGT for different parcel-selection methods?

Yes, this is one of Crowdfolio’s core features. When you want to sell a position, Crowdfolio compares four methods for you: minimise-tax, FIFO, LIFO and highest-cost-first. For example, you might see that selling via LIFO saves you $500 in tax compared to FIFO. This allows you to make an informed decision: is the extra documentation worth the tax saving? Crowdfolio puts this decision in your hands before you trade, rather than leaving it to your broker’s default method. This is a significant advantage over generic portfolio trackers that don’t forecast parcel-level outcomes. Seeing how CGT calculated under each method often changes the optimal decision.

Q: Does Crowdfolio account for the 12-month CGT discount in its forecasts?

Yes, Crowdfolio automatically identifies which parcels are eligible for the 50% CGT discount (held for 12+ months) and which are not. When forecasting CGT, it applies the discount only to eligible parcels. This is particularly useful when you’re deciding which parcels to sell: selling a parcel that qualifies for the discount is generally more tax-efficient than selling one that doesn’t. Crowdfolio’s forecasts show the tax impact with and without the discount, so you can see the exact benefit of waiting a few more days or weeks to reach the 12-month threshold. That transparency answers the frequent question of how CGT calculated both before and after applying the 12‑month discount.

Rebalancing and Tax-Aware Portfolio Management

Q: How should I rebalance my portfolio while minimizing CGT?

Tax-aware rebalancing means considering the tax impact of each trade before you execute it. Instead of simply selling enough of your overweight positions to hit your target allocation, you should ask: which parcels should I sell to minimize tax? Can I harvest losses to offset the gains? Should I wait a few weeks to reach the 12-month discount threshold? Crowdfolio helps by forecasting the CGT outcome of different rebalancing strategies. For example, you might see that selling via LIFO instead of FIFO saves you $1,000 in tax, or that harvesting a loss in a different holding offsets the entire rebalancing gain. Crowdfolio’s portfolio tracking and rebalancing tools are designed to show these trade-offs before you commit. If you want a rule of thumb for how CGT calculated when rebalancing, start by modelling each candidate sale and comparing the net after‑tax impact.

Q: What is portfolio drift, and how does it relate to CGT?

Portfolio drift occurs when your actual portfolio allocation diverges from your target allocation due to different returns on different holdings. For example, if you target 50% ASX 200 ETF and 50% growth stocks, but growth stocks have performed better, you might end up 40% ETF and 60% growth. Rebalancing brings you back to your target. However, rebalancing often triggers capital gains, so you need to weigh the benefit of rebalancing (staying on target) against the tax cost. Crowdfolio helps by showing your current drift and the exact CGT cost of rebalancing. This allows you to decide: is rebalancing worth the tax bill, or should I wait? Some investors rebalance only when drift exceeds a threshold (e.g., 5%), and Crowdfolio helps you track this and make tax-aware decisions. Use the tool to see how CGT calculated for candidate trades and pick the lowest after-tax cost approach.

Q: Should I ever avoid rebalancing to save on CGT?

Sometimes, yes. If rebalancing would trigger a large capital gains tax bill, and your drift is small, it may be better to wait. However, this depends on your risk tolerance and investment goals. If your portfolio has drifted significantly from your target allocation, rebalancing is important even if it triggers tax. Crowdfolio helps you make this decision by showing the exact tax cost and allowing you to compare it against the benefit of rebalancing. For example, if rebalancing costs $500 in tax but brings your allocation back to your target, is that worth it? Crowdfolio provides the information; you make the decision. The practical question investors ask is: how CGT calculated will change my portfolio’s after-tax return if I rebalance now versus later? Crowdfolio gives that answer.

Accountant-Ready Reports and Record-Keeping

Q: What does “accountant-ready” mean, and why does it matter?

An accountant-ready report is a detailed, well-organized summary of your trades and capital gains that your accountant can use directly in your tax return without needing to ask follow-up questions or re-do calculations. It includes all the details the ATO requires: dates, quantities, prices, cost bases, holding periods, capital gains or losses for each trade, and a summary of net capital gains or losses for the year. Instead of handing your accountant a pile of broker statements and hoping they get it right, you give them a clear, auditable report. Crowdfolio generates accountant-ready reports that include all this information in a format your accountant will appreciate. This saves time, reduces errors, and gives your accountant confidence in the numbers. If your accountant asks how CGT calculated for a particular set of trades, the Crowdfolio report shows the calculations line by line.

Q: What details should an accountant-ready CGT report include?

A comprehensive CGT report should include: (1) a list of all purchases with date, quantity, price, and cost base; (2) a list of all sales with date, quantity, sale price, proceeds, and capital gain or loss; (3) the holding period for each parcel (days held); (4) identification of which parcels qualify for the 50% CGT discount; (5) total capital gains and losses for the year; (6) net capital gain or loss; (7) any carried-forward losses from prior years; and (8) notes on any unusual transactions or tax strategies (e.g., tax-loss harvesting, wash-sale considerations). Crowdfolio generates all of this automatically, and you can export it as a PDF or CSV for your accountant. The report makes it transparent how CGT calculated across each parcel and trade so your accountant can rely on the numbers.

Q: How do I provide my CGT information to my accountant?

The best approach is to export your CGT report from Crowdfolio (as a PDF or spreadsheet) and provide it to your accountant along with any supporting documents (e.g., broker statements, dividend statements). Make sure the report is clearly labeled with your name, the financial year, and a summary of net capital gains or losses. Your accountant will use this to fill in the capital gains section of your tax return. If your accountant has questions, refer them to Crowdfolio’s detailed parcel-level records, which show exactly how each gain or loss was calculated. This transparency and detail is what makes a report “accountant-ready.”

Common Mistakes and How to Avoid Them

Q: What is the most common mistake investors make with CGT calculation?

The most common mistake is not tracking the cost base correctly. Many investors remember the purchase price but forget to include transaction costs (brokerage, stamp duty, advisor fees) in the cost base. This understates the cost base and overstates the capital gain. For example, if you bought shares for $10,000 plus $100 in brokerage, your cost base is $10,100, not $10,000. Over many trades, these small errors add up to significant tax overstatements. Crowdfolio automatically includes all transaction costs in the cost base, so this mistake is avoided. If you ever doubt how CGT calculated for a past trade, Crowdfolio’s audit trail shows exactly which components were included.

Q: What happens if I don’t keep records of my trades?

If you can’t prove your cost base to the ATO, the ATO may assume your cost base is zero, meaning your entire sale proceeds are treated as a capital gain. This can result in a much larger tax bill. The ATO expects you to keep records for five years after the end of the financial year in which the transaction occurred. Records should include purchase and sale confirmations, broker statements, and any documentation of your lot-selection method (if you used specific identification). Crowdfolio maintains a complete audit trail of your trades and lot selections, making it easy to provide proof to the ATO if needed. That audit trail also documents how CGT calculated for each disposal, which is invaluable in an audit.

Q: Can I change my lot-selection method after I’ve sold shares?

No, you cannot. Once you’ve sold shares, your lot-selection method is locked in (unless you can prove to the ATO that you specified a different method at the time of sale). This is why it is worth deciding which parcel you are selling before you trade, and keeping the records that support it. Identification rests on your own records rather than on an instruction to your broker. If your broker doesn’t support your preferred method, you should document your choice in writing (e.g., an email to your broker). Crowdfolio helps by forecasting the tax outcome of different methods before you trade, so you can make an informed decision and ensure your broker executes it correctly. Understanding in advance how CGT calculated under each method prevents disputes later.

Part IVA and Tax Avoidance Risks

Q: What is Part IVA, and how does it affect my CGT planning?

Part IVA is the ATO’s General Anti-Avoidance Rule, which allows the ATO to deny tax benefits from schemes that have a dominant purpose of avoiding tax. For most DIY investors, Part IVA is not a concern because normal investment activities (like rebalancing or tax-loss harvesting) are not considered tax avoidance. However, aggressive strategies—like wash sales, round-tripping, or artificial loss creation—can trigger Part IVA scrutiny. The key is that your trading strategy must have a genuine commercial purpose beyond tax avoidance. Crowdfolio flags potential Part IVA risks (such as wash sales) so you can adjust your strategy and stay compliant. That way you can see how CGT calculated when transactions are accepted versus when a benefit is denied under Part IVA.

Q: How does the wash-sale rule interact with tax-loss harvesting?

Wash sales are reached through Part IVA rather than a dedicated rule, so there is no day count to satisfy. If you sell at a loss and buy the same, or substantially the same, asset back, the Commissioner can weigh the manner, substance and timing of the arrangement and cancel the benefit, whether the gap was a day or a month. Buying a genuinely different security does change your position and is the safer path, but it is that change in exposure which matters, not elapsed time. Crowdfolio flags wash-sale risk and leaves the judgement to you, for example when considering a similar (but not identical) holding instead.

Q: What counts as “substantially the same” for wash-sale purposes?

There is no statutory test, because Australia has no wash-sale statute. TR 2008/1 speaks of the same, or substantially the same, asset, and says the term wash sale has no precise meaning. In practice, two different ETFs tracking the same index leave your exposure effectively unchanged, so selling one and buying the other invites the Part IVA question. Selling a broad index ETF and buying something with a genuinely different mandate does change your position. Crowdfolio’s wash-sale flagging considers the security type and helps you identify safe alternatives for loss harvesting. Knowing which replacements avoid wash-sale risk clarifies how CGT calculated when you pursue a harvest strategy.

Advanced Tax Planning Strategies

Q: Can I use capital losses to offset dividend income?

No, capital losses can only offset capital gains, not other income like dividends or salary. This is an important limitation to understand. If you have a large capital loss in a year but no capital gains, you cannot use the loss to reduce your taxable income in that year. However, you can carry the loss forward indefinitely to offset capital gains in future years. This is why it’s important to track cumulative losses over time. Crowdfolio shows your available loss carryforward, so you know how much loss is available to offset future gains. That visibility helps you plan when and how CGT calculated over a multi-year horizon.

Q: Should I harvest losses at the end of the financial year?

Yes, if you have unrealized losses (parcels trading below cost base), the end of the financial year (30 June) is a good time to harvest them. By selling at a loss, you can offset capital gains from earlier in the year or carry the loss forward. Be careful, though: harvesting a loss in late June and buying the same holding back in July is the exact pattern Part IVA is aimed at, and waiting a set number of days does not fix it, because Australia has no 30-day window. Crowdfolio identifies harvesting opportunities and flags repurchases that look like a wash sale, citing the relevant ATO guidance, so you can plan end-of-year strategies with the Part IVA question in view. When planning, model how CGT calculated both before and after harvesting to confirm it’s worth executing.

Q: What if I have losses from previous years that I haven’t used yet?

Carried-forward losses are automatically applied to offset capital gains in the current year. You don’t need to do anything special; the ATO applies them automatically when you lodge your tax return. However, you do need to track them and ensure you have documentation of the loss (the original sale confirmation and cost base). Crowdfolio tracks your cumulative losses and shows how much is available to offset current-year gains, making it easy to see the benefit of harvesting new losses or using old ones. That way you always understand how CGT calculated after applying carried-forward losses.

Comparing Methods: A Worked Example

Q: Can you show me a concrete example of how different parcel-selection methods affect CGT?

Absolutely. Let’s say you own 200 shares of XYZ Corp:

• Parcel A: 100 shares purchased on 1 January 2022 at $10 (cost base $1,000)
• Parcel B: 100 shares purchased on 1 July 2023 at $12 (cost base $1,200)
• Current price: $15 per share
• You want to sell 100 shares today (1 August 2024)

Under FIFO, you sell Parcel A: capital gain = $1,500 − $1,000 = $500. Since it’s held over 12 months, you get the 50% discount: taxable gain = $250.

Under LIFO, you sell Parcel B: capital gain = $300. Parcel B was bought on 1 July 2023 and sold on 1 August 2024, which is more than 12 months, so it is also discount-eligible: taxable gain = $150.

Under highest-cost-first you also sell Parcel B, so the outcome is the same as LIFO: taxable gain = $150.

If your marginal tax rate is 39% (including the Medicare levy), FIFO costs $97.50 in tax ($250 x 39%) while LIFO costs $58.50 ($150 x 39%). LIFO is the cheaper choice here by $39, because both parcels qualify for the discount and Parcel B has the smaller gain. However, if you also had capital losses to harvest, the calculation would change. This is why Crowdfolio forecasts all methods: to help you see which is best for your specific situation. To be explicit about the core question many investors ask: this example shows how CGT calculated differently under FIFO, LIFO and highest-cost-first.

Compliance and Record-Keeping Best Practices

Q: What records should I keep for CGT purposes?

You should keep: (1) broker statements for all purchases and sales; (2) confirmation emails or receipts showing the exact date, quantity, and price; (3) documentation of transaction costs (brokerage, stamp duty); (4) evidence of your lot-selection method (if you used specific identification); and (5) any correspondence with your broker about your trading strategy. The ATO requires you to keep records for five years after the end of the financial year in which the transaction occurred. Crowdfolio stores all this information and can export it in a format suitable for your records or for providing to the ATO if audited. Those exports also demonstrate how CGT calculated for each trade, which simplifies audits.

Q: How do I prove my cost base to the ATO if audited?

If the ATO audits your CGT, you’ll need to provide evidence of your cost base. This includes broker statements showing the purchase price, date, and quantity; documentation of transaction costs; and any other expenses incurred to acquire or sell the asset. Crowdfolio generates detailed reports that show all this information in an organized, auditable format. If you’re audited, you can export your Crowdfolio report and provide it to the ATO as evidence of your calculations. This transparency and detail is a major advantage of using a proper CGT tracking system. The report explicitly shows how CGT calculated so you and your advisor can defend the position.

Q: Should I use the same lot-selection method for all my trades?

No, you can use different methods for different trades, but you must be consistent within each trade and document your choice. For example, you might use FIFO for most trades but use specific identification for a large rebalancing trade to minimize tax. However, once you’ve chosen a method for a specific trade, you can’t change it later. The key is to be deliberate about your choice and document it clearly. Crowdfolio allows you to specify your method for each trade and maintains a complete audit trail, making it easy to prove your choices to the ATO. That audit trail also shows how CGT calculated under the method you selected.

Frequently Asked Questions About Crowdfolio’s Approach

Q: Why doesn’t Crowdfolio require broker logins?

Crowdfolio prioritizes your privacy and security. Broker logins are a security risk because they give Crowdfolio access to your entire broker account, including sensitive information like bank details and payment methods. By using CSV exports instead, Crowdfolio only accesses the information you explicitly provide (trade history and holdings), and you maintain full control. This approach is also more reliable: if Crowdfolio’s connection to your broker breaks, your data is not at risk. CSV exports work with any broker, so you’re not locked into a specific platform.

Q: How often should I update my Crowdfolio data?

You should update your data whenever you make a trade or whenever you want to check your current CGT forecast. For active traders, this might be daily or weekly. For buy-and-hold investors, monthly or quarterly updates are usually sufficient. Crowdfolio makes it easy to re-export your CSV from your broker and upload it to Crowdfolio, so updates take just a few minutes. The more current your data, the more accurate your CGT forecasts.

Q: Can Crowdfolio track holdings across multiple brokers?

Yes, Crowdfolio can combine data from multiple brokers. You simply export a CSV from each broker and upload them all to Crowdfolio. Crowdfolio will merge the data and show your complete portfolio across all brokers. This is particularly useful if you use different brokers for different asset classes (e.g., CommSec for Australian shares, Stake for US shares) and want to see your total CGT exposure.

Q: Is my data secure in Crowdfolio?

Crowdfolio uses industry-standard encryption and security practices to protect your data. Your data is encrypted in transit, and Crowdfolio does not share it with third parties without your consent. CSV import means you can use Crowdfolio without connecting a broker account at all, which is the most privacy-preserving option. You maintain full control over your data and can delete it at any time. For more information on Crowdfolio’s security and privacy practices, visit Crowdfolio’s website. If you want to verify how CGT calculated from your uploads, you can review the on-screen calculations before saving any changes.

Summary and Next Steps

Calculating capital gains tax correctly is crucial for tax-efficient investing. The key concepts are: (1) CGT is calculated as sale proceeds minus cost base, with a 50% discount for assets held over 12 months; (2) parcel-level lot selection (FIFO, LIFO, specific) significantly affects your tax outcome; (3) tax-loss harvesting and Part IVA wash-sale risk require careful planning; and (4) detailed record-keeping is essential for compliance and audit defense. Crowdfolio simplifies CGT calculation by forecasting your tax outcome before you trade, showing you the impact of different parcel-selection methods, identifying tax-loss harvesting opportunities, and flagging wash-sale risks. By putting the tax cost inside the trading decision, Crowdfolio helps you build a more tax-efficient portfolio. If you’re wondering how CGT calculated for your own portfolio, try uploading your CSV to Crowdfolio and see the parcel-level calculations instantly.
