When you run an ABN, the ATO does not pre-fill your tax return the way it does for PAYG employees. Your employer does not summarise your income through Single Touch Payroll. Nobody sends the ATO a tidy annual statement of your business expenses. That responsibility sits entirely with you — and it comes with a records standard that is meaningfully higher than the one that applies to salary-and-wage earners.

This Pillar is the deep dive for sole traders, contractors, freelancers and every other Australian who earns some or all of their income under an ABN. It builds on our EOFY Records Hub, which covers the full records landscape for all Australian taxpayers. Here we go narrow and specific: the exact record categories the ATO expects from ABN income earners before 30 June 2026, why they expect them, and what it takes to get them sorted.

Why ABN holders carry a higher records burden

The ATO's record-keeping requirements are set out in the Income Tax Assessment Act and the Tax Administration Act. For individual employees, the core obligation is to substantiate deduction claims — keep the receipts, keep the bank statements, keep the WFH hours log. Income is pre-filled through Single Touch Payroll; deductions need evidence.

For ABN holders, the obligation runs in both directions. You must be able to prove your income and your expenses. The ATO does not receive automatic income reports for most business earnings, though gig platform income is increasingly reported directly by platform operators. The ATO relies on you to report accurately, and it expects you to be able to substantiate every line if it asks.

An audit of a sole trader is a more demanding process than an audit of an employee. The ATO is not just checking that you have receipts — it is checking that your reported income matches your invoices, that your expense claims represent genuine business costs rather than personal ones, and that your GST obligations have been handled properly if you are registered. The records you keep now are the evidence you would produce in that situation.

1. Business income records

Every dollar of ABN income needs to be traceable. The ATO expects you to be able to reconcile your reported income to your tax return and to account for any gap between what you invoiced and what you received — bad debts, write-offs, refunds.

Keep copies of every invoice issued during the year, including cancelled invoices. Tax invoices for GST-registered traders must show your ABN, the GST component, the date, the recipient and a description of the supply. Invoices for non-registered traders need the same information minus the GST breakdown.

Keep bank statements for your business account showing every deposit. Ideally these reconcile cleanly to your invoices. In practice they rarely do without bookkeeping — which is precisely why bank account separation matters (more on that below).

If you earn through digital platforms — ride-sharing apps, task platforms, freelance marketplaces — download and keep the year-end income summary each platform generates. The ATO's data-matching reach into platform income has expanded considerably in recent years. What is not declared is likely to surface.

If you receive cash payments, record each one at the time it is received. Cash income is an area the ATO scrutinises closely in trade and service businesses, where unexplained gaps between bank deposits and declared income draw audit attention.

2. Business expense records — the foundation of every deduction

Every business deduction you claim needs a record. The rule is the same as for PAYG employees — receipts, tax invoices or equivalent written evidence — but the scope of deductible expenses for sole traders is broader, and that breadth makes the records obligation larger.

For each deductible business expense you need a tax invoice or receipt showing the supplier's identity, their ABN if GST-registered, the date, the amount, and a description of what was purchased. For purchases above $82.50 GST-inclusive, you need a full tax invoice to claim the GST component on your BAS.

Common business expense categories include professional subscriptions and memberships, insurance premiums (business, public liability, professional indemnity), software licences, mobile phone and internet in the business-use proportion, marketing and advertising, accounting and bookkeeper fees, bank fees on business accounts, and subcontractor invoices.

Two areas that generate frequent claims problems: mixed personal and business expenses, which require honest apportionment based on genuine business-use evidence; and repairs versus improvements to assets, where repairs are deductible in the year incurred and improvements must be depreciated. The distinction has a clear definition in tax law. The ATO knows which direction most people prefer to push it.

3. BAS and GST records

If your ABN income is expected to exceed $75,000 in a financial year, you are required to register for GST and lodge Business Activity Statements. Registration brings its own records obligations on top of your income tax ones.

Keep copies of every BAS lodged during the year. Keep the supporting records that fed into each BAS — the income and expense figures that drove the GST calculation. The ATO expects these records to be retained for five years from the date each BAS was lodged.

For input tax credits — the GST you can reclaim on business expenses — a full tax invoice is the document that entitles you to the credit. For purchases above $82.50, a receipt alone may not be sufficient if it does not show the supplier's ABN and the GST amount. Collecting proper tax invoices from suppliers at the time of purchase is considerably easier than chasing them up in June.

4. Vehicle records

The vehicle deduction is one of the highest-value claims available to sole traders — and one of the most audited. The reason is straightforward: it is also one of the most overstated.

The two main methods for claiming vehicle expenses are the logbook method and the cents-per-kilometre method. The logbook method captures the actual business-use percentage of all vehicle running costs: fuel, registration, insurance, servicing and depreciation. The cents-per-km method is simpler but capped at 5,000 kilometres per year.

A valid logbook covers 12 continuous weeks of representative car use. It must record the date, destination, purpose, odometer readings at the start and end of each journey, and the total kilometres. Once established, a logbook is valid for five years — but if your circumstances change materially (new vehicle, different business activity pattern), start a new one. For the logbook method, keep fuel, servicing, insurance and registration statements for the full year, plus the vehicle purchase records for depreciation.

The GoTax Deduction Grabber app has a built-in vehicle logbook that records trips and maintains the running business-use percentage automatically. Running it from now through to 30 June gives you a valid partial-year record and sets you up for the full logbook period in 2026-27. Download it free at gotax.com.au/deduction-grabber.

5. Working from home records for ABN holders

The WFH claim for sole traders is more nuanced than the employee version, and it is worth understanding the difference before you lodge.

PAYG employees can only claim running expenses — the additional electricity, internet and phone costs attributable to working from home. They cannot claim occupancy expenses (rent, mortgage interest, council rates) because they could otherwise perform their role at the employer's premises.

Sole traders can legitimately claim occupancy expenses where they operate a business genuinely from a dedicated home workspace, but there is a significant caveat. Claiming occupancy expenses on a home you own can affect your main residence CGT exemption when you eventually sell. The proportion of the home used for business, and the length of time it was used that way, can create a partial capital gains liability on sale. This is not a reason to avoid the claim — it is a reason to understand the implication, keep the right records, and be able to calculate the effect accurately when the time comes.

For running expenses: keep a contemporaneous hours log — a diary, spreadsheet or app record of WFH hours recorded at or near the time. For occupancy expenses: keep your lease or mortgage documents, council rate notices, insurance and utility bills in your name, and a floor plan or measurement establishing the dedicated workspace as a proportion of total home floor area.

6. Asset register and depreciation records

When you purchase equipment, tools, technology or other assets for your business, the cost is generally not immediately deductible — it is depreciated over the asset's effective life. The exception is the instant asset write-off, which allows immediate deduction of the full cost for eligible assets in the year of purchase, subject to thresholds and eligibility rules that have changed frequently in recent years.

You need an asset register: a record of every depreciating asset used in the business, its purchase price, the date acquired, the depreciation method applied and the running written-down value. Most bookkeeping tools maintain this automatically. If you are managing it manually, a spreadsheet updated each year is the minimum.

For each depreciating asset, keep the purchase invoice showing the cost, the acquisition date, and evidence of business use. For motor vehicles being depreciated under the logbook method, keep the purchase contract and any improvement invoices separate from routine repair invoices — they are treated differently for tax purposes.

The instant asset write-off thresholds and eligibility conditions depend on your business entity structure and turnover and have changed multiple times. Check current ATO guidance at ato.gov.au before applying the write-off, and keep records showing your business met the eligibility criteria in the year of claim.

7. Superannuation records

Personal superannuation contributions can be tax-deductible for sole traders who meet the eligibility requirements — but only if one specific step is completed before lodging the return.

That step is lodging a Notice of Intent to Claim a Deduction with your superannuation fund, and receiving their written acknowledgment. Without both documents, the contribution is not deductible. The ATO is firm on this. There is no retrospective fix after lodgement.

Records to keep: super fund statements showing the contribution amounts and dates; the completed Notice of Intent to Claim a Deduction; and the fund's written acknowledgment. Keep these for five years from the date you lodge the relevant return.

If you are tracking your concessional contribution cap — currently $30,000 per year — keep records of all concessional contributions from all sources: employer contributions if any, and personal contributions you intend to claim. Exceeding the cap has tax consequences. Your own records are faster to work from than waiting for ATO correspondence.

8. Bank account separation — the record-keeping habit that saves days

The single most effective record-keeping practice for any ABN holder is the simplest: maintain a dedicated bank account for business income and expenses. Every dollar of business income goes in. Every business expense comes out. Personal spending never touches it.

When business and personal finances are mixed, preparing the tax return — or explaining it in an audit — requires reconstructing business transactions from a combined bank statement. That means reviewing every transaction, categorising it, and being able to justify the business purpose of each item that looks personal. Depending on transaction volume, that can take days.

With a dedicated business account, the bank statement becomes the first reconciliation pass. Add receipts and invoices as supporting documents and the categorisation work is largely complete. Most bookkeeping tools, including eCashBooks, connect to your bank feed and automate a significant portion of this through the year.

If you have not separated accounts yet, there is still time before 30 June to open a dedicated business account and shift operations to it for the rest of the financial year. Even a partial year of clean records is substantially better than none.

Year-round record-keeping: the GoTax stack for sole traders

The records challenge for ABN holders is fundamentally a year-round problem, not a June problem. The receipt you did not collect in August is still missing in June. The invoice you issued in October but did not record properly still requires reconstruction before lodgement. 30 June is the deadline — the work happens continuously.

Two tools address the two sides of this.

GoTax Deduction Grabber is the free mobile app for capturing individual expenses on the go. Photograph receipts as they happen, log vehicle trips, track WFH hours, record transactions by category. It handles day-to-day evidence collection that keeps records complete without any end-of-year sprint. Free at gotax.com.au/deduction-grabber, available on iOS and Android.

eCashBooks (ecashbooks.com) is the year-round bookkeeping tool built specifically for sole traders. Not Xero. Not MYOB. Both are full accounting systems designed for businesses with employees, payroll runs, inventory management and significant BAS complexity. eCashBooks is purpose-built for sole-trader simplicity — clean records of business income and expenses, maintained through the year, ready for the annual return without a major June reconciliation project.

Together, eCashBooks and GoTax form the complete tax stack for self-employed Australians: eCashBooks handles year-round bookkeeping; GoTax handles the annual return with registered tax agent review. The combination replaces the default 'Xero plus accountant' workflow many sole traders fall into — at a fraction of the cost, with tools designed for the simplicity that sole-trader work actually requires.

Ready to lodge? GoTax handles the ABN return

When your records are in order, your return is straightforward. GoTax handles ABN, sole trader, contractor, freelancer and self-employed tax returns online, with registered tax agent review and lodgement to the ATO included in the price.

The ABN Tax Return is $140 at gotax.com.au/abn-tax-return. The same price applies for contractors at gotax.com.au/contractor-tax-return, freelancers at gotax.com.au/freelancer-tax-return, and self-employed Australians at gotax.com.au/self-employed-tax-return. No appointments. No waiting rooms. A registered tax agent reviews your return before it is lodged — not software acting alone, but a qualified professional checking your work before it reaches the ATO. That is the difference between GoTax at $140 and myGov at no charge.

Frequently asked questions

Do sole traders have to keep tax records in a specific format?

No. The ATO accepts digital records provided they are clear, legible, complete and can be produced promptly on request. Photos of paper receipts, PDF invoices, app-generated logs and exported bank statements are all acceptable. The requirement is that records are genuine, unaltered and retained for the full retention period.

How long do sole traders have to keep tax records?

Five years from the date you lodge the return is the standard rule. For depreciating assets: five years from the date the asset is fully depreciated or disposed of. For capital gains records: five years from the date of disposal. Any matter in dispute with the ATO must be retained until fully resolved, regardless of the standard period.

Can I claim business expenses I paid in cash?

Yes, but only with written evidence showing the amount, the date, the supplier and what was purchased. 'Paid cash and did not get a receipt' is not a substantiated deduction. For cash payments to contractors or subcontractors, confirm that GST-registered suppliers have issued a proper tax invoice if you intend to claim the input tax credit on your BAS.

What records do I need if I use one vehicle for both business and personal travel?

The logbook method is the most rigorous approach and typically produces the highest deduction for vehicles with significant business use. It requires 12 continuous weeks of contemporaneous trip records establishing the business-use percentage and remains valid for five years. The cents-per-kilometre method allows up to 5,000 business kilometres without a logbook, but the ATO still expects you to be able to explain how the figure was calculated — it should reflect actual travel patterns, not a round estimate.

Can I deduct the full cost of a new laptop or piece of equipment?

Possibly, depending on the purchase cost and the instant asset write-off rules that apply in the year of purchase. These thresholds and eligibility conditions have changed several times in recent years. Check ATO guidance at ato.gov.au before applying the write-off. If the cost exceeds the current threshold, the asset will need to be depreciated over its effective life. Keep the purchase invoice and document why your business met the eligibility criteria in the year of claim.
