GST Refund CA Certificate (Indirect Taxes) | CA Guide 2026

It is a certificate issued by a Chartered Accountant or Cost Accountant confirming that the incidence of the tax for which a refund is claimed has not been passed on to any other person. It is mainly required for GST refund claims and legacy indirect-tax refunds to satisfy the doctrine of unjust enrichment.

It is required under Section 54 of the CGST Act, 2017 read with Rule 89(2)(m) of the CGST Rules, 2017. The certificate confirms that the tax burden has not been transferred to the buyer, so the refund does not unjustly enrich the claimant.

A CA or CMA certificate is generally required where the refund claim exceeds ₹2 lakh. Below that threshold, a self-declaration by the applicant is usually accepted. Always verify the current threshold, as rules may change.

It is the principle that a person should not be refunded a tax whose burden they have already recovered from someone else, usually the customer. The refund certificate confirms the burden was borne by the claimant and not passed on.

A practising Chartered Accountant or a Cost Accountant (CMA) can issue it. For GST refunds, the CGST Rules specifically permit certification by a CA or a Cost Accountant.

Under Section 54(8) of the CGST Act, unjust enrichment does not apply to certain refunds, such as refund of unutilised input tax credit, refund of tax on zero-rated supplies (exports), refund of wrong tax paid, or where the tax was not passed on. In these cases the certificate may not be needed.

There is no fixed government fee. Professional charges depend on the complexity of the refund, the volume of transactions, and the verification involved. Agree the scope and fee in writing beforehand.

Documents can be shared digitally and a signed PDF issued, but the certificate itself is signed by the professional after verification. It cannot be self-generated from any website.

The certificate relates to a specific refund claim and period. It is generally used for that claim and does not have a separate statutory validity, but it should be current and consistent with the refund application.

Yes. The refund can be rejected or queried if the UDIN is missing, the certificate is inconsistent with returns, the computation is wrong, or unjust enrichment is not adequately addressed.
