You can use the Mark as Unfiled option to unfile your return in Zoho Books. There are three cases where this is applicable and here’s what you should do.

Case 1: You’ve already filed your GSTR-1 in the GST portal

If you had not included certain transactions in your GSTR-1 but you had filed your returns, you can mark the return as ‘Unfiled’. In this case, you will have to include the transactions manually in the next return that you are filing.


If there’s any update in the transaction, you will have to amend them manually under section 9A/9C of GSTR-1 in the GST Portal for the next return that you file.

Case 2: You’ve not filed your GSTR-1 in GST portal

In case you had accidentally marked your return as filed without filing your return in the GST portal, you have the option to unfile it. In this case, once you mark it as unfiled, you can update your transactions and push the transactions again. The changes you’ve made will reflect in the GST Portal and you can file your returns.

Here’s how you can unfile your returns:

Case 3: You’ve filed your GSTR-1 directly through Zoho Books

In case you need to edit a transaction that you’ve included in your GSTR-1 filing that has been filed directly through Zoho Books, you can unfile your GSTR-1 return.

If you need to unfile a return that is not the recent GSTR-1 filing, you need to unfile all GSTR-1 returns from the most recent filing in reverse sequential order until you reach the return you want to unfile.

Note: Unfiling the GSTR-1 return that has been filed directly through Zoho Books will not unfile the return in the GST Portal.

Note: Any changes you make to transactions after unfiling your GSTR-1 return should be manually amended when you file your future returns.
