Tax Tips Every Sole Trader & Senior Should Know in 2025

ABN Reactivation & GST: Charge GST Only When Required

  • You must register for GST when your GST turnover reaches AUD 75,000 in any rolling 12‑month period. Register within 21 days once you meet or expect to meet the threshold.
  • If you’re below AUD 75,000, GST registration is optional—do not add GST to invoices if you’re not registered. Include your ABN and clearly state that no GST applies.
  • Taxi and ride‑sourcing services must register from day one, regardless of turnover.
  • Ensure invoices meet ATO requirements (ABN, date, description, price, and GST treatment) to avoid disputes and support clients’ record‑keeping.

Seniors (67+): SAPTO Can Reduce Your Income Tax

  • If you are age‑pension age (currently 67) and eligible for the Age Pension or another listed government payment, you may qualify for the Seniors and Pensioners Tax Offset (SAPTO).
  • SAPTO is non‑refundable: it can reduce your tax payable to AUD 0, but it does not create a refund by itself.
  • Eligibility also depends on rebate income thresholds, including taxable income and certain contributions. Some unused SAPTO may be transferable between spouses when both are eligible.

Claiming Your Accountant or Tax Agent Fees

  • Costs for managing your tax affairs—such as lodging via a registered tax agent, recognised tax advice, tax software (apportioned), travel to obtain tax advice, and certain litigation costs—are deductible. Keep invoices and evidence.
  • You cannot claim fees paid to unregistered advisers or general financial advice unrelated to tax management; split invoices fairly if they cover multiple people.

Why Working with an Accountant Matters

Whether you’re reactivating an ABN, deciding if GST applies, or assessing SAPTO eligibility, the rules are precise and time‑sensitive. Engaging a qualified accountant ensures correct lodgements, ATO‑compliant invoices, and the proper application of Australian taxation law—so you keep more of your money and stay fully compliant.
