GST-registered businesses may make mistakes in their GST returns at various levels:
- Transaction level - e.g. wrong treatment applied or no supporting documents to substantiate the GST treatment; or
- GST reporting level - e.g. extracting wrong data for GST F5 reporting, specific GST adjustments such as input tax apportionment are not made on consolidated figures, etc.
Businesses are encouraged to conduct the ASK Annual Review for GST returns filed in each financial year as regular reviews will help businesses detect errors early.
Before conducting the ASK Annual Review, if you discover any GST errors in past GST returns, you should immediately rectify the errors and notify IRAS by filing GST F7 (i.e. “Disclosure of Errors on GST Return”) for the affected periods. Please refer to
Correct Mistakes in Past Returns for the guidelines and process on filing GST F7.
What are the benefits of using the ASK Annual Review?
IRAS will waive the 5% late payment penalty if businesses come forward with the disclosure on past error(s) within 1 year from the statutory filing date of their last GST return for the financial year reviewed. For more information, please refer to
IRAS’ Voluntary Disclosure Program.
What should I do after the ASK Annual Review?
If errors are discovered in the course of your review, you should complete and submit the declaration form and relevant template(s) available in ASK: Declaration Form on Completing Annual Review & Voluntary Disclosure of Errors (143KB). IRAS may request you to send in your working papers.
If no error is discovered during your ASK Annual Review, you should submit the Declaration Form to demonstrate your commitment to be GST-compliant.
