ATO's TPAR pre-fill is live — but timing your lodgment matters

August 24, 2026

Contractor in construction, cleaning, IT or courier services? Don't lodge just yet.

The ATO's Taxable Payments Annual Report (TPAR) data is now pre-filling automatically into contractor tax returns — part of a broader push to make small business tax as simple as an individual return. The catch: the ATO is advising contractors to hold off lodging until after 28 August, so the pre-fill data has time to fully populate and match against what's been reported. A timely reminder for any client who wants to lodge early — patience now avoids a flagged return later.
