What is GST Form 7?

If you have made errors in your previous GST F5, F7, and F8, you can file GST F7 to amend the errors.

Here are the requirements to file GST Form 7:

A) Administrative Concession for Correcting Errors

You may adjust the errors made in your next GST F5 due to administrative concession if you meet both of these criteria.

  • The Net GST amount in error (i.e., output tax error - input tax error) for all the affected prescribed accounting periods is not more than $1,500
  • The total non-GST amounts in error for (each of) the affected accounting period(s) is not more than 5% of the total value of supplies declared in the submitted GST return (i.e., Box 4).
  • The 5% rule applies to the total value of the taxable purchases (i.e., Box 5) in the circumstance where there was no supply made during the accounting period.

Do note that the administrative concession doesn't apply to the following items:

  • Errors that affect Boxes 9 to 12, 14, and 15 of your past GST F5
  • Errors made in your last return, GST F8

You can use the GST F7 calculator to determine whether you are qualified for the administrative concession.

B) File claim for overpaid or wrongly paid GST

You can file for GST F7 to claim a refund if you have paid the wrong GST amount earlier.

If you are unsure of the GST Treatment, you can clarify the GST Treatment with IRAS before filing GST F7.

Here is the following information that you need to provide them:

  1. Explanation of the error or issue involved
  2. Total GST to be refunded for all accounting period impacted

You should claim a GST refund within the range of five years from the end of the relevant accounting periods.

What is GST Form 8?


You will need to file GST Form 8 when you cancel your GST Registration within 30 days when you stopped making taxable supplies and do not intend to make taxable supplies in the future.

You are required to:

  • Submit the GST F8 and account for GST within one month from the end of the prescribed accounting period stated on the return; and
  • Settle all outstanding GST returns and payments, if any.
