If you qualify for a GST credit, you need to claim it within the 4-year time limit for claiming GST credits.
4-year credit time limit
Your eligibility for a GST credit ceases unless it is included in an assessment prior to the end of the 4-year credit time limit. The 4-year credit time limit ends 4 years after the lodgment due dates of the BAS for the tax period in which you could have first claimed the GST credit. If you report GST on a cash basis, you can claim a GST credit in the tax period when you pay for a purchase. If the payment is spread over several tax periods, the 4-year time limit for claiming the credit applies separately to each instalment. For those using a non-cash basis, the earliest tax period to claim a GST credit is the first period in which either an invoice is issued, or a payment – partial or full – is made for the purchase.
Lodging your BAS on time with all GST credits that you are liable for ensures that your credits are assessed correctly within the allowed period to protect your entitlement. Regular checks and reconciliation can help you identify errors early enough to make corrections before the 4-year deadline.
Even if the 4-year limit is nearing, you need to continue to follow your GST reporting obligations. Claiming credits you are not eligible for may lead to penalties and interest if reviewed. Once the 4-year credit period has expired, there is no way to recover the GST credit, as the time limit cannot be extended under any circumstances. For accurate advice, you can also get in touch with a tax accountant Melbourne.
When a GST credit is included in an assessment
A GST credit that you have included in your BAS for a tax period is included in your assessment for that tax time. The GST credit is included in your assessment on the day you file your BAS.
A GST credit that you have included in your BAS for a tax period is included in your assessment for that tax period. The GST credit is included in your assessment on the day you lodge your BAS. Where the ATO amends your assessment to include additional GST credits, those credits will also be included in the assessment. These credits are included on the day the ATO makes the amended assessment.
When a GST credit is not included in an assessment
The following actions do not result in GST credits being reflected in your assessment:
- Applying for a private ruling
- Requesting an amendment to your assessment
- Lodging a revised activity statement (which is treated as a request for an amendment)
- Making a voluntary disclosure
- Lodging an objection
If you believe you are entitled to GST credits that have not been included in your assessment, it is advisable to explore your options early rather than leaving it until the last minute.
Period of review
The 4-year credit time limit is separate from the period of review. The period of review is the time limit during which the ATO can make changes to your assessment, usually 4 years from the lodgment due dates of your BAS. This timeframe can be extended by agreement or reset if an amendment is made. Certain exceptions allow the ATO to amend your assessment after the period of review ends. However, the 4-year credit time limit is not one of these exceptions.
Even if the ATO can amend your assessment – for instance, while still within the period of review or under another exception – the ATO cannot include unclaimed GST credits if the 4-year credit timeframe has passed and no other exception applies. In practice, this means the ATO can adjust your assessment for overpaid or underpaid GST, overclaimed credits, or increasing/decreasing adjustments. However, the ATO cannot include unclaimed credits if your entitlement to them has passed.
Conclusion
Understanding the 4-year GST credit time limit is essential to protect your entitlements. To ensure you receive all eligible credits, lodge your BAS on time, accurately include all GST credits, and perform regular reconciliations to catch errors early. Once the 4-year limit expires, unclaimed credits cannot be recovered, regardless of any amendments or review periods. Staying proactive with your GST reporting and seeking professional advice from Reliable Melbourne Accountants when needed can help you maximise your credits while avoiding penalties or interest for incorrect claims.
