The sole trader's guide to receipt keeping (without accounting software)

Somewhere between "ABN registered" and "first BAS due", every sole trader gets told they need accounting software. Some do. But if you're a freelancer, contractor or side-gig operator without employees, without inventory, and without complex GST, the compliance core is much smaller than the software industry suggests: know your income, keep evidence of your expenses, keep it five years. Here's the system that covers it.

What the ATO actually requires of you

As a sole trader you must keep records of income (invoices you issued, payments received) and expenses (receipts and tax invoices for what you claim), generally for five years. The records can be digital. If you're GST-registered you also need valid tax invoices for purchases over $82.50 (GST-inclusive) to claim input tax credits, and your BAS figures need to be reconstructible from your records.

Notice what's not in that list: double-entry ledgers, bank feeds, reconciliation workflows. Those are conveniences for complexity you may not have.

The three-part system

Part 1: A separate bank account

Not legally required for a sole trader, but it does more work than any app: run every business dollar through one account and the account statement becomes your income record and your expense checklist. Come tax time you walk the statement and confirm every line has a matching receipt, instead of fishing business transactions out of your grocery account.

Part 2: A receipt archive that fills itself

Most sole-trader expenses arrive by email now — software subscriptions, hosting, insurance, equipment orders, fuel cards. Connect that inbox (or set an auto-forward rule) so those capture themselves; photograph the occasional paper receipt on the spot. Give each receipt a category as it lands — a starter set of six or eight based on the return's own buckets is plenty, and we've written up an ATO-shaped starter list.

Two habits specific to sole traders:

• Tag mixed-use purchases (phone, internet, the laptop that's also the family computer) the moment they land. The business percentage is a conversation for your accountant; the tag means you can find every candidate in one search.
• Keep the tax invoices proper. Over $82.50 GST-inclusive, an order confirmation isn't a tax invoice — if you're GST-registered and the vendor sent a casual receipt, ask for the real thing while they still remember you.

Part 3: One export at year end

With income on the bank statement and expenses categorised in the archive, tax time is mechanical: open the tax-year summary, check the uncategorised pile is empty, export the CSV, and hand your accountant (or your own myTax session) totals per category with every receipt behind them retrievable on demand. No reconciliation ceremony, because there was nothing to reconcile — every number traces to a document.

Quarterly, if you're GST-registered

BAS needs your GST collected and GST paid per quarter. The same archive covers the paid side: filter the quarter, read the GST column off the export. If your turnover is under the $75,000 registration threshold and you haven't registered, you get to skip this entirely — one of the genuine perks of staying small.

The limits of software-free

This system assumes simple. Hire an employee and you have payroll, super and STP reporting — get software. Carry inventory, invoice on terms with debtor-chasing, or take investment, and proper books earn their subscription. And if your accountant insists on Xero because that's how their practice runs, weigh their fee savings against the subscription — sometimes the software is really for them, which can still be worth it.

Until one of those is true, a bank account, a self-filling receipt archive and a CSV export is not the budget version of bookkeeping. For a simple sole trader, it is bookkeeping.
