The indirect tax system in many countries has seen a lot of changes and improvements after the emergence of the GST system. GST has one major feature named Input Tax Credit (ITC). ITC is a process through which businesses can claim credit for the taxes paid on inputs and hence use it to compensate their output tax liabilities.

But this is not so easy. The proper functioning of ITC requires an up-to-date matching process. In this article, we will get a deep understanding of how the ITC matching process works, important procedures, best practices, documentation requirements etc.

Understanding matching in GST credit

Matching GST credit means a reconciliation process that takes place between the ITC claimed by the buyer and the taxes paid by the supplier. This means it ensures that the credit claimed by the buyer tallies perfectly with the actual taxes paid by the supplier. The process plays an important role in the maintenance of the integrity and accuracy of the GST system.

It assures the proper functioning of the GST system, promotes transparency and prevents tax evasion. Under the GST regime, every eligible tax credit claimed by the supplier shall have a relevant tax invoice. If not tax invoice then at least some other supporting documents are uploaded by the supplier. The GSTN (Goods and Services Tax Network) facilitates the matching process and ensures that the credit claimed is genuine.
