How Long to Keep Tax Records in Australia (With Examples)

Keep most tax records for five years from the date you lodge your tax return. For example, if you lodged your 2025–26 return on 15 October 2026, keep the records behind it until at least 15 October 2031. Some records need longer: companies must keep financial records for seven years under the Corporations Act 2001, records for a CGT asset are kept for five years after the CGT event (usually the sale), and records for depreciating assets for five years from your last claim. If the Australian Taxation Office (ATO) ever comes knocking with questions, you'll have everything you need right there.

Quick Guide to Australian Tax Record Retention

Getting a handle on how long to keep tax records is a non-negotiable part of good financial housekeeping, whether you're an individual or running a business. The ATO sets the standard rule: most records need to be kept for a five-year period after you've lodged the relevant tax return. So, what does this actually cover? It’s a pretty broad range of documents—essentially, anything you used to figure out your tax submission. This includes things like:

• Income statements from your employer(s)
• All those receipts and invoices for your expense claims
• Bank statements that show interest earned
• Dividend statements if you hold shares
• Any records detailing capital gains or losses

Of course, it's not just about holding onto old receipts. Staying on top of current tax rules is just as important, because every deduction or concession you claim is only as good as the records that prove your spending.

While the five-year rule is a solid benchmark for individuals, businesses often face longer requirements depending on the type of record. For business records, the ATO's five-year period generally runs from when the record was prepared or obtained, or the transaction was completed, whichever happened later.

Tax Record Retention Periods At a Glance

To make things easier, here's a quick summary of the minimum timeframes you need to know, as required by the ATO and other key Australian bodies.

• Individuals: 5 years from the date you lodge your tax return (ATO)
• Sole traders and other businesses: 5 years from when the record was prepared or obtained, or the transaction was completed, whichever is later (ATO)
• Companies: financial records for 7 years after the transactions are completed, under the Corporations Act 2001 (administered by ASIC)
• Capital gains tax (CGT) assets: 5 years after the CGT event, such as selling the asset (ATO)
• Depreciating assets: 5 years from your last claim for decline in value (ATO)
• Employer payroll and super records: 5 years (ATO)
• SMSF records: 5 or 10 years depending on the record (ATO)
• Fringe benefits tax (FBT): 5 years from the date you lodge the FBT return (ATO)

This list serves as a great starting point, but remember that specific situations—like a dispute with the ATO or an amended assessment—can extend these periods. If you're in a dispute with the ATO, keep the records until the dispute is resolved, even if the five years has passed. It always pays to be organised.

The Five Year Rule for Individuals and Sole Traders

For most everyday Aussies and sole traders, the magic number to remember for tax records is five. This is the standard rule of thumb set by the Australian Taxation Office (ATO) and it's the bedrock of good personal tax compliance.

Here's where a lot of people get tripped up: the clock on that five-year period doesn't start at the end of the financial year. It actually starts ticking from the exact date you lodge your tax return. Getting this right is crucial, as it ensures you've got the proof to back up every claim and all your declared income for the full five years.

Calculating Your Retention Period

So, how does this work in practice? It's pretty straightforward. Let’s say you lodged your 2025–26 tax return on 15 October 2026. That means you need to hang onto all the related paperwork for that return until at least 15 October 2031. If you toss them out before then, you could be left high and dry if the ATO comes knocking for a review. This rule covers the whole gamut of documents that support what you've put in your return. Keeping these records organised, whether in a shoebox or a cloud folder, is the key to proving both your income and your expenses without any last-minute panic.

Key Records to Keep for Five Years

Basically, you need to keep any document that helped you or your tax agent prepare your return. Having a system makes life a whole lot easier if the ATO ever asks for more information. The absolute must-haves include:

• Income Statements: This includes your income statement from each employer (available in ATO online services through myGov), Centrelink statements, or details from any other income source.
• Expense Receipts: All those receipts for work-related gear, uniforms, self-education courses, or home office costs.
• Bank and Dividend Statements: Any documents showing the interest you've earned or dividends you've received.
• Logbooks: If you're claiming car expenses using the logbook method, your logbook is non-negotiable. A logbook can be used for up to five years, so keep it and your odometer records for five years after the last income year you rely on it.
• Depreciating Assets: Receipts for items you claim depreciation on, like a laptop or tools. Keep these for five years from your last claim for decline in value, not five years from the year you bought them.

What counts as a proper record? For most expenses, the ATO wants written evidence such as a receipt or invoice from the supplier showing the supplier's name, the amount, what you bought, the date you paid and the date of the document. Records need to be in English if the expense was incurred in Australia. A bank or credit card statement on its own usually isn't enough, because it doesn't show what you bought. If your total work-related expense claims are $300 or less you don't need written evidence, but you still need to be able to show you spent the money and how you worked out your claim.

The most critical thing to remember is that this responsibility is 100% yours. Even if you use a fantastic tax agent to lodge your return, you're the one who must be able to pull out the supporting documents for the entire five-year period.

If you'd rather have a registered tax agent prepare your return, our individual tax return service lists what to bring, and we check every deduction you're entitled to. You still keep the records for the five years.

Employing staff? Sole traders and other businesses with employees also need to keep payroll records, such as pay records, completed super choice forms and proof of the super contributions paid for each employee, for five years.

The Seven-Year Rule for Companies

If you’re running a business as an individual or sole trader, the five-year rule is a pretty solid benchmark. But for companies and their directors, the goalposts shift. You’re playing a different game with a more stringent set of rules. The answer to "how long to keep tax records in Australia" for a company's financial records is a definitive seven years. This isn't an arbitrary number cooked up by the ATO. This extended retention period is set by the Corporations Act 2001, which is administered by the Australian Securities and Investments Commission (ASIC). It's a legal requirement that sits alongside the standard tax rules, meaning companies and their directors absolutely must stick to this longer timeframe to stay compliant with corporate law.

Why Seven Years Is the Magic Number

So, why the extra two years? It comes down to the complex nature of a company. Unlike a sole trader, a company has deeper legal and financial duties, particularly to its shareholders and creditors. The seven-year paper trail ensures there's complete transparency and accountability in a company's financial history. Under Australian corporate law, specifically section 286 of the Corporations Act 2001, financial records must be kept for seven years after the transactions they cover are completed. It's a non-negotiable part of corporate governance, and ignoring it can bring serious penalties for the company and its directors.

The Company Records You Must Keep

The seven-year rule isn't just for a few select documents; it covers everything that explains your company's financial position and performance. Getting this wrong can lead to hefty fines or, in serious cases, legal action against the directors. Here’s a quick list of the core records you need to hold onto for the full seven years:

• Financial Statements: This includes your Profit and Loss Statements and Balance Sheets.
• Tax and BAS Records: Every single Business Activity Statement and company tax return.
• General Ledgers: The detailed logs of all your financial transactions.
• Asset Registers: All paperwork related to buying, depreciating, and selling company assets.

At the end of the day, the buck stops with the company directors. It’s on you to ensure these records are kept properly for the entire seven-year period. Think of it less as a tax chore and more as a fundamental pillar of good corporate governance and staying on the right side of the law in Australia.

If keeping company records in order is falling behind, our small business accountants in Sydney look after tax returns, BAS and payroll for sole traders, companies and trusts, using the accounting software you already have, such as Xero or MYOB.

Special Record Rules for Capital Gains Tax Events

When it comes to the question "how long to keep tax records in Australia," Capital Gains Tax (CGT) events are the big exception that can catch people out. Unlike your standard income or expense receipts, the clock for keeping records on CGT assets—like property or shares—starts much, much later. You really need a long-term mindset for this one. The rule itself is simple enough, but it’s where a lot of people get tripped up. You must keep the records for a CGT asset for the whole time you own it, and then for five years after the CGT event (which is usually when you sell or dispose of it). If you make a capital loss, keep the records until you've used the loss against a later gain and the amendment period for that later year (generally two years for individuals) has passed.

Calculating the CGT Record Timeline

Let's walk through a real-world example. Say you bought an investment property way back in 2010. You held it for years, and then finally signed a contract to sell it in March 2024 (the CGT event happens when you sign the sale contract, not at settlement). The gain is declared on your 2023–24 tax return, which you might lodge in September 2024. Under the ATO's CGT rule, you need to keep the records for five years after the CGT event, which takes you to March 2029, but because the same records support the return you lodged in September 2024, the safer approach is to keep them until at least September 2029. That means hanging onto every single record related to that property—from the initial purchase contract in 2010 right through to the final sale documents in 2024. Tossing them out early could leave you completely exposed if the ATO ever queries the transaction down the track, as you’d have no way to prove your cost base.

Essential CGT Documents to Retain

Having the right paperwork is non-negotiable for correctly calculating your capital gain or loss. If you want to get into the nitty-gritty of this, you can learn more about when you pay capital gains tax in our detailed guide. The key records you absolutely must keep include:

• Purchase and Sale Contracts: These are your primary evidence, establishing the original purchase price and what you eventually sold it for.
• Proof of Ownership: Think title deeds for property or share certificates for investments.
• Records of Capital Improvements: Kept all your invoices for that big renovation? Good. These costs form part of the asset’s cost base, which can reduce your final tax bill.
• Incidental Costs: Don't forget the other expenses like stamp duty, legal fees, and real estate agent commissions. Every one of these receipts helps build an accurate picture of your costs.

Superannuation and Deceased Estates: When the Rules Change

The standard five-year rule isn't a one-size-fits-all solution, especially when you step into the more specialised worlds of superannuation and deceased estates. These areas have their own unique timelines, and getting them right is critical for staying compliant. If you’re managing a self-managed super fund (SMSF), you’ll find the record-keeping demands are far more extensive. While many of the usual financial documents still fall under the five-year rule, a whole host of others need to be kept for much, much longer.

SMSF Record Retention Timelines

As a trustee, you need to be across the different retention periods for specific SMSF documents. It's not something you can afford to get wrong.

• 10 Years: Key governance documents have a decade-long retention period. This includes minutes of trustee meetings and decisions, records of any changes to trustees, trustee declarations (kept for 10 years or while the person remains a trustee, whichever is longer), and copies of all reports given to members.
• 5 Years: Your fund's accounting records, annual operating statements and statements of financial position, and copies of annual returns must be kept for at least five years.

Handling a Deceased Estate

When you're the executor or administrator of a deceased estate, you take on responsibility for the deceased person's tax affairs. This is a significant duty, covering everything right up to their final tax return. As a general guide, keep the deceased's tax records until the estate's tax affairs are finalised, and then for at least five years after the last return (the date of death return or the final trust return) is lodged. Keep records about assets passed to beneficiaries, such as property or shares, for longer, because the beneficiaries will need them to work out their own cost base when they eventually sell. This responsibility is all about ensuring that any questions from the ATO down the track can be answered accurately and promptly, giving you peace of mind during what is already a difficult time. You can learn more about the complexities involved in managing a deceased estate in our dedicated article.

Best Practices for Storing Tax Records Securely

Knowing how long you need to keep your tax records is only half the battle. How you store them is just as critical for staying compliant and ensuring you can find what you need, when you need it. Peace of mind is the goal here. Whether you're a fan of old-school paper files or prefer everything in the cloud, the principles are the same: security, organisation, and accessibility. For your physical records, a dedicated, fireproof filing cabinet tucked away in a secure home office is a fantastic, reliable option. I always recommend labelling folders clearly by financial year and then by category (e.g., "FY2025–26 – Work Expenses") so you can pull them out in a flash. Whatever you do, avoid storing them in damp places like the garage or a shed, as that's a surefire way to have them degrade over time.

Digital Storage Solutions

Going digital is where you gain huge advantages in accessibility and backup security. Storing your records in the cloud or within dedicated accounting software means you can access them from anywhere—a massive step up from a filing cabinet locked in your office. Here are a few solid digital methods to consider:

• Cloud Storage: Services like Google Drive or Dropbox are incredibly convenient. The trick is to create a logical folder structure that mirrors how you'd file paper records. And it goes without saying, but always use strong, unique passwords and enable two-factor authentication.
• Accounting Software: Platforms such as Xero or MYOB are brilliant because they often have built-in document storage. This allows you to link a digital copy of a receipt directly to the transaction it relates to, which is a game-changer for organisation.
• External Hard Drive: This is a good backup solution, but make sure the drive is encrypted and, crucially, stored in a separate physical location from your main computer. A backup isn't much use if it gets destroyed in the same incident as the original!

No matter which method you land on, having a consistent backup strategy is completely non-negotiable. The ATO is perfectly happy to accept digital copies of your records, but only if they are a true and clear reproduction of the original document. You can explore various ways of record keeping to figure out what system works best for you and your business.

Once the legal retention period is finally up, don't just toss your old files in the bin. Make sure you are securely disposing of old tax records with a cross-cut paper shredder to protect your sensitive personal and financial information from falling into the wrong hands.

Changes from 1 July 2027: for capital gains that accrue from that date, the 50% CGT discount is replaced with cost base indexation and a minimum tax of 30% on certain gains. Gains that accrued before 1 July 2027 keep the 50% discount, and different rules apply to new residential builds. See the ATO's capital gains tax reform page.
