How to Cancel GST Registration Online: Step-by-Step Guide, Form REG-16 & GSTR-10 Rules

Whether closing down a business, falling below the mandatory annual turnover threshold, or transitioning from a proprietorship to a private limited company, formally cancelling an inactive GST registration is essential.

Simply stopping return filings without cancellation is a dangerous mistake: late fees under Section 47 accumulate at up to ₹50/day per return indefinitely, and tax authorities can issue best judgment assessment orders under Section 62 along with recovery proceedings.

In this guide, we provide a complete step-by-step walkthrough for cancelling your GST registration online using Form GST REG-16, calculating tax on closing stock, and filing the mandatory GSTR-10 Final Return.

Valid Grounds for Cancelling GST Registration (Section 29(1))

Under Section 29(1) of the CGST Act, a registered person or their legal heir can voluntarily apply for cancellation under the following circumstances:

1. Discontinuation or Closure of Business: The enterprise has permanently ceased commercial operations.
2. Transfer of Business: Full transfer of business due to sale, merger, demerger, amalgamation, or lease.
3. Change in Constitution: Changing entity structure (e.g., Sole Proprietorship converted to Partnership Firm or Private Limited Company—requiring a fresh GSTIN).
4. Turnover Below Threshold: Annual aggregate turnover has fallen consistently below ₹40 Lakhs for goods or ₹20 Lakhs for services.
5. Death of Sole Proprietor: The legal heir can apply for cancellation of the deceased proprietor’s GSTIN.

The Closing Stock Liability (Section 29(5))

Before submitting your cancellation application, you must calculate your liability on closing inventory.
Under Section 29(5), every registered person whose registration is cancelled must pay an amount equivalent to the higher of:

1. The Input Tax Credit availed on inputs held in stock, inputs contained in semi-finished or finished goods held in stock, and capital goods or plant and machinery.
2. The output tax payable on the open market value of such stock.

Capital Goods Stock Formula:

For plant and machinery or capital goods, the ITC to be paid back is reduced by 5 percentage points per quarter from the date of invoice. If machinery was purchased 3 years ago (12 quarters), the unexpired useful life liability is computed and discharged through electronic cash or credit ledger.

Step-by-Step Online Filing Process (Form GST REG-16)

Step 1: Log in to the GST Portal

Visit gst.gov.in and log in with your valid credentials.

Step 2: Navigate to Application for Cancellation

Go to Services → Registration → Application for Cancellation of Registration.

Step 3: Fill Out the 3 Core Tabs

The application consists of three structured sections:

• Basic Details: Verify your legal name, trade name, and correspondence address. (Update your future communication address if closing the current premises).
• Reason for Cancellation: Select from the dropdown (Discontinuance of business, Change in constitution, Turnover below threshold, etc.). Enter the exact Date from which cancellation is sought.
• Particulars of Closing Stock & Tax Payable: Enter the value of inputs, semi-finished stock, and capital goods on hand. The system computes the tax payable under CGST, SGST, and IGST. Discharge this amount using available electronic cash or credit ledger balances.

Step 4: Verification & Digital Signature

Tick the declaration, select the authorized signatory from the dropdown, enter the place of filing, and sign via DSC (mandatory for Companies and LLPs) or EVC (OTP on registered mobile/email for Proprietors).

Step 5: Order in Form GST REG-19

Once submitted, an ARN is generated. The Proper Officer will verify the application and issue a formal order of cancellation in Form GST REG-19 within 30 days. During this period, your GSTIN status will display as “Suspended”.

The Mandatory Final Step: GSTR-10 (Final Return)

Filing Form REG-16 and receiving REG-19 does NOT complete your legal obligations.
Under Section 45 of the CGST Act, every person whose registration is cancelled must file a Final Return in Form GSTR-10.

Critical GSTR-10 Deadlines:

• GSTR-10 must be filed within three months from the date of cancellation OR the date of the cancellation order, whichever is later.
• Failure to file GSTR-10 attracts statutory late fees of ₹200 per day (₹100 CGST + ₹100 SGST) under Section 47, capped at ₹10,000.
• If GSTR-10 is ignored, the department issues a notice in Form GSTR-3A, followed by best-judgment assessment orders.

Frequently Asked Questions (FAQs)

Can the tax officer initiate recovery after GST registration is cancelled?

Yes. Under Section 29(3), the cancellation of registration does not affect the liability of the person to pay tax and other dues under this Act for any period prior to the date of cancellation, whether or not such tax is determined before or after the cancellation.

Can a cancelled GST registration be revoked?

If an officer cancelled your GSTIN suo-motu due to non-filing of returns, you can apply for revocation of cancellation in Form GST REG-21 within 90 days (extendable by an additional 180 days on sufficient cause) after filing all overdue returns and paying applicable late fees and taxes.
