New Delhi, Nov 10 (PTI) GST Network today said businesses can now make changes to the forms uploaded on the portal to claim transition credit.

"The facility to revise Form GST TRAN-1 declaration has been introduced on the GST Portal for taxpayers who had already filed it prior to November 9, 2017," GSTN said in a statement.

Form TRAN-1 declaration is to be filed by persons registered under GST law who wish to claim credit for taxes paid under pre-GST regime.

The functionality to fill the claim form was provided on the GSTN portal in August 2017.

The government in September allowed for one-time revision of TRAN-1.

The facility to revise TRAN-1 declaration has been enabled for taxpayers who had already filed it, said GSTN, the company which developed the IT backbone for the new indirect tax regime.

Revision can be either an increase or decrease of credit in comparison to the original credit.

If the revision is to reduce the credit claimed previously then the taxpayer will be able to file only if he has sufficient balance in his credit ledger," GSTN said.

Revision of transition credit claims: taxpayers may amend Form GST TRAN 1; reductions allowed only if ledger balance suffices. Taxpayers registered under GST may use a one time amendment facility on the GST portal to revise previously filed Form GST TRAN-1 declarations, permitting increases or decreases in transition credit claims; reductions are allowed only if the taxpayer has sufficient balance in the GST credit ledger.
