Section 45 of CGST explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Section 45 of the CGST Act, 2017 requires every registered person whose GST registration has been cancelled to furnish a final return in Form GSTR-10 within three months of the date of cancellation or the date of the cancellation order, whichever is later. The final return settles closing stock and any tax payable on inputs and capital goods held at cancellation.
What Section 45 Says — In Plain English
Section 45 is the "closing the account" provision of GST. When your registration is cancelled — whether you asked for it or the officer cancelled it — you cannot simply walk away. In plain English, the law says you must file one last return, called the final return, to formally wind up your GST account. This return exists so that the Government can recover any credit or tax attached to stock and capital goods you were still holding on the day your registration ended.
The provision applies to a registered person who was required to furnish returns under Section 39(1). The final return must be filed within three months of the date of cancellation or the date of the order of cancellation, whichever is later, in the prescribed form and manner. That prescribed form is GSTR-10 under Rule 81. It is a one-time return, quite different from the routine monthly or quarterly GSTR-3B and GSTR-1.

Applicability & Scope
- Applies when GST registration is cancelled — whether on the taxpayer's own application or by the proper officer (suo motu).
- Applies only to persons who were filing regular returns under Section 39; it does not apply to composition taxpayers, Input Service Distributors, non-resident taxable persons, or those deducting/collecting tax under Sections 51/52.
- The three-month clock runs from the later of the cancellation date and the order date.
- It is a one-time obligation that survives even after the GSTIN is inactive.
Worked Examples
Example 1 — Computing the due date. A registered dealer applies for cancellation with effect from 31 July 2026. The proper officer passes the cancellation order on 10 August 2026.
| Event | Date |
|---|---|
| Effective date of cancellation | 31 Jul 2026 |
| Date of cancellation order | 10 Aug 2026 |
| Later of the two | 10 Aug 2026 |
| GSTR-10 final return due by | 10 Nov 2026 |
The dealer must file GSTR-10 by 10 November 2026, declaring closing stock and paying back ITC or output tax on inputs and capital goods held on the day before cancellation, as required by Section 29(5).
Example 2 — Quantifying the liability. Suppose at cancellation the dealer held inputs on which ₹40,000 ITC had been claimed, and capital goods (a machine) purchased 2 years earlier on which ₹90,000 ITC was originally taken. For the machine, ITC is reversed on a pro-rata basis over its useful life of 5 years (60 months): with 36 months remaining, the reversal is ₹90,000 × 36/60 = ₹54,000. Under Section 29(5) the dealer must pay the higher of the ITC involved (₹40,000 + ₹54,000 = ₹94,000) or the tax on the transaction value of that stock and capital goods. The resulting amount is declared and paid through GSTR-10.
Step-by-Step in Practice
- File all pending periodic returns (GSTR-1/GSTR-3B) up to the cancellation date.
- Take stock of inputs, semi-finished/finished goods and capital goods held on the day before cancellation.
- Compute the Section 29(5) liability — higher of ITC involved or tax on transaction value (capital goods pro-rated over 5 years).
- Prepare and submit Form GSTR-10 within the three-month window.
- Discharge the tax/ITC payable and retain the acknowledgement as proof of a clean exit.
Common Mistakes & Practical Notes
- The final return is GSTR-10 — a one-time return, not to be confused with the annual return GSTR-9 or the periodic GSTR-3B.
- Failing to file all periodic returns up to the cancellation date before filing the final return.
- Overlooking capital goods, on which ITC must be reversed on a pro-rata basis under Section 29(5) read with Rule 44.
- Ignoring the return after cancellation — this triggers a notice in Form GSTR-3A and continued exposure.
- Assuming cancellation ends all obligations; the final return is the step that actually closes the lifecycle.
Penalties, Timelines & Related Sections
Failure to file GSTR-10 first draws a notice in Form GSTR-3A under Section 46, giving 15 days to comply. Continued default can lead to best-judgment assessment under Section 62 and late fee under Section 47. Section 45 links to Section 29 (cancellation, and the sub-section 29(5) liability on stock/capital goods), Section 39 (periodic returns), Section 46 (notice to defaulters), Section 47 (late fee) and Rule 81 (Form GSTR-10). Together they ensure a clean, tax-settled exit from GST.
Recent Amendments & Context
Section 45 has remained substantively stable, but the compliance context is significant: the GSTR-10 late fee has been capped at ₹500 (₹250 CGST + ₹250 SGST) under rationalisation notifications, and the GST Council has run several amnesty windows allowing pending GSTR-10 returns to be filed with a reduced late fee. These schemes are periodic, so a person whose registration was cancelled should check for any live amnesty before filing to minimise late fee exposure.
