Have you checked your fuel tax credit rates since 1 April 2026, or are you still using old figures without realising it?
If you run a business that uses fuel, this is not a small detail. It can quietly cost you money every single quarter. And the worst part? Most people do not notice until it is too late.
Let’s get straight to it.
Have the Fuel Tax Credit Rates Changed?
Yes, fuel tax credit rates have changed from 1 April 2026. If you claim fuel tax credits in Australia, you must use the updated rates for fuel acquired from this date. Using outdated rates can lead to incorrect claims, which means missed refunds or potential compliance issues with the ATO.
These changes did not happen randomly. They follow the temporary reduction in fuel excise by 60.9%. Since fuel tax credit rates are tied directly to excise, any shift like this flows straight into what you can claim.
What’s the Real Problem Here?
You are busy running your business. Fuel receipts pile up, BAS deadlines come around fast, and you rely on your systems or accountant to “just handle it.”
But fuel tax credit rates are not fixed forever. They change regularly due to adjustments in fuel excise. If your system or process has not been updated from 1 April 2026, you could be:
- Claiming less than you should
- Claiming more than allowed
- Carrying forward errors into future BAS lodgements
And let’s be honest. When was the last time you double-checked your fuel rates?
What Actually Changed from 1 April 2026?
From 1 April 2026, the Australian Taxation Office updated fuel tax credit rates in line with fuel excise indexation.
These updated rates apply to:
- Fuel acquired on or after 1 April 2026
- Different fuel types like diesel, petrol, and alternative fuels
- Different business uses, such as on-road and off-road activities
But you cannot just apply one rate across everything.
For fuel acquired before 1 April 2026, you must use the old rates when preparing your March BAS. On the other hand, you must use the new rates for your April BAS for fuel acquired from 1 April 2026 onwards.
The exact rate you can claim depends on:
- The type of fuel you use
- How you use that fuel in your business
- Whether road user charges apply
And what if you run heavy vehicles?
If you operate heavy vehicles, this change is even more important for you. From 1 April to 30 June 2026, the heavy vehicle road user charge is set to zero.
That changes how much you can claim.
If you are using fuel in heavy vehicles on public roads during this period, you can claim fuel tax credits equal to the full excise duty paid on that fuel.
Why This Matters More Than You Think
Fuel is one of the highest operating costs for many Australian businesses. Even a small change in fuel tax credit rates can impact:
- Your cash flow
- Your profit margins
- Your compliance with ATO rules
And here is the uncomfortable truth.
If your claims are wrong, the ATO will not ignore it forever. Reviews and audits do happen. Fixing past mistakes is always harder than getting it right up front.
How Do You Make Sure You’re Using the Right Rates?
You do not need to overcomplicate this. But you do need to be intentional.
Ask yourself:
- Are your accounting systems updated for the new rates?
- Is your bookkeeper or accountant aware of the April 2026 changes?
- Are you separating fuel use correctly between on-road and off-road?
If you hesitate on any of these, that is your signal to act.
Practical Steps You Can Take Today
- Check the latest fuel tax credit rates on the ATO website
- Confirm your software reflects the updated rates from 1 April 2026
- Review your last BAS if it overlaps the change period
- Speak with your tax professional if you are unsure
It is a small effort now that can save you from a bigger problem later.
The Cost of Doing Nothing
Doing nothing is still a decision. And it often leads to:
- Lost refunds that you will never recover
- Incorrect claims that need corrections
- Extra stress during tax time
You work hard for your revenue. Why let simple errors chip away at it?
A Quick Reality Check
Think about your last fuel bill. Now think about that amount across a full year.
Now ask yourself.
Are you completely confident that every litre is being claimed at the correct rate?
If the answer is not a clear yes, it is worth taking a closer look.
Frequently Asked Questions
What date do the new fuel tax credit rates apply from?
The new rates apply to fuel acquired from 1 April 2026. Fuel purchased before that date must still use the previous rates, even if reported later.
Do I need to amend previous BAS statements?
Only if you used incorrect rates for the relevant period. If you are unsure, it is best to review and confirm with a professional.
Are the rates the same for all fuel types?
No. Rates vary depending on the type of fuel and how it is used in your business.
What happens if I use the wrong rate?
You may under-claim or over-claim. Under-claiming means lost money. Over-claiming may require corrections and could attract ATO attention.
Where can I find the official rates?
You can check the latest rates directly on the Australian Taxation Office website.
