How BAS due dates work
- Quarterly BAS is due on 28 October, 28 February, 28 April and 28 July for the four quarters of the income year.
- If a due date falls on a weekend or public holiday, you have until the next business day to lodge and pay.
- If you lodge online, you may be eligible for an extra 2 weeks for a quarterly BAS. You may also get extra time through a registered tax or BAS agent. The October to December quarter is the exception, because its due date already includes a one-month extension.
- You must report monthly if your GST turnover is $20 million or more or the ATO has told you to. You can choose to report monthly if it is lower.
Tax figures for 2026-27 that affect asset finance
The car limit applies to passenger vehicles designed to carry fewer than 9 passengers and a load of less than one tonne, so it does not apply to every vehicle. These are the 2026-27 figures. Check the ATO for the figures that apply when you buy, because they are set each financial year.
- Instant asset write-off: eligible businesses with aggregated turnover under $10 million can claim an immediate deduction for the business portion of an asset that costs less than $20,000, and the $20,000 limit is permanent from 1 July 2026. The limit applies to each asset.
- Assets that cost $20,000 or more can generally go into the small business pool, which depreciates at 15% in the first income year and 30% in each year after.
- Car limit: $69,883 for 2026-27. It is the most you can use to work out depreciation on a passenger car first used or leased in the 2026-27 income year, and the instant asset write-off cannot be used for a car that costs $20,000 or more.
- GST credit on a car: when a car costs more than the car limit, the most you can generally claim is one-eleventh of the limit, which is $6,353 for 2026-27.
- Luxury car tax thresholds for 2026-27: $91,661 for fuel-efficient vehicles and $80,809 for other luxury vehicles. You cannot claim a credit for luxury car tax.
Planning a purchase around these dates
- The year an asset can be claimed depends on when it is first used or installed ready for use, so ask your accountant how that applies, especially around 30 June.
- Finance takes time to arrange. Start early if a date matters, and ask your lender or broker what the steps and timing are for your situation.
- A cash rate decision does not move every loan by the same amount. A fixed rate stays the same for the fixed period.
- Compare the whole cost of any offer, not only the repayment.
