How to cancel GST registration online (Form GST REG-16): steps and mistakes

Last updated 14 Oct 2026 · India

Short answer. If you no longer need GST — business closed, turnover below the threshold, or transferred — you apply for cancellation of registration on the GST portal. The application is filed in Form GST REG-16 from the registration menu after you log in (GST portal registration user guide; gst.gov.in). Cancellation does not wipe earlier periods: file pending returns and pay tax, interest and late fee first, or the portal will block or delay the application. Until cancellation is approved, returns (including nil) stay due.

Why people cancel

Buyers often say they took a GST number, never used it, then faced “7000 ka penalty” on piled-up nil returns. Cancellation stops future return liability. It is not an amnesty for past periods.

Before you open REG-16

Log in at gst.gov.in and list every return period not filed (GSTR-1 / IFF and GSTR-3B, or CMP-08 if composition).
File the oldest pending returns first; pay late fee and interest shown.
Clear any outstanding tax in the electronic liability ledger.
Download your registration certificate and past acknowledgments for your records.
Note the reason for cancellation (closure, turnover below threshold, change in constitution, etc.) as the form asks.

What REG-16 is

REG-16 is the taxpayer's application to cancel registration. After you submit, the tax officer may seek clarification; once approved, you receive an order and the GSTIN is cancelled from the effective date in that order. Stock and capital-goods implications can apply when you exit — ask your CA before you click submit if you still hold stock.

Common mistakes

Stopping nil returns without applying. Until cancellation is approved, every period still needs a return.
Applying with returns pending. Clear filings and dues first so the application is not rejected or kept pending.
Assuming cancellation deletes old late fees. Past fees remain payable.
Wrong effective date or reason. Match the form to when you actually stopped supplies.
Ignoring input-tax-credit and stock. Cancellation can trigger tax on certain stock; get numbers checked.
