Question 1

How far back can I amend my BAS for fuel tax credits?

Accepted Answer

You can amend your BAS for fuel tax credits up to 4 years from the original due date. For example, Q1 FY2021-22 (due 28 October 2021) can be amended until 28 October 2025.

Question 2

What are common reasons for under-claiming fuel tax credits?

Accepted Answer

Common reasons include: claiming all fuel at the lower on-road rate instead of off-road rate, not claiming auxiliary equipment apportionments (concrete mixers get 30%, refrigerated trucks 10%), missing fuel purchases, and not claiming for generators or off-road machinery.

Question 3

How do I amend my BAS for fuel tax credits?

Accepted Answer

Log into the ATO Business Portal, go to Activity Statements, select the relevant period, and revise your Label 7D amount. You'll need records to support the increased claim. The ATO will process the amendment and either reduce your liability or issue a refund.

Question 4

How much could I recover from under-claimed fuel tax credits?

Accepted Answer

For FY2025-26, the difference between off-road (50.8c/L) and on-road (19.2c/L) rates is over 30c per litre. A business using 50,000L annually that claimed at the wrong rate could recover over $15,000 per year, or $60,000+ over 4 years.
