Switching From Regular GST to Composition Scheme: ITC Reversal and Timing

Switching From Regular GST to Composition Scheme: ITC Reversal and Timing
CA Nikhil Gupta·July 2026· Rule 3-6, CGST Rules GST COMPLIANCE

Moving from regular GST to the Composition Scheme is not just a form filing — it requires reversing input tax credit already claimed on stock and capital goods sitting in the business, within a strict 60-day window that catches many small businesses off guard.

Step 1: File Form GST CMP-02

A registered person eligible for composition must file Form GST CMP-02 on the GST portal, intimating the decision to opt for the scheme, before the start of the financial year for which the option is to apply. This is a declaration, not an approval-based application — but it starts the clock on the next, more consequential step.

Step 2: Reverse ITC using Form GST ITC-03 — within 60 days

Because composition dealers cannot hold input tax credit, anyone switching from regular registration must reverse the ITC already availed on:

This reversal is filed through Form GST ITC-03, and must be completed within 60 days from the commencement of the relevant financial year (i.e., the date the composition scheme becomes effective).

⚠ The amount payable can be significant: A business with substantial closing stock built up under regular registration — inventory-heavy traders and manufacturers in particular — can face a meaningful cash outflow at the point of switching, since the ITC reversal must be paid by debiting the electronic credit or cash ledger. This is worth modelling before deciding to switch mid-cycle rather than discovering it after CMP-02 is already filed.

How the capital goods reversal is calculated

The credit attributable to the remaining useful life of a capital good (assumed as 60 months / 5 years from the invoice date) is what must be reversed. In practical terms: take the original ITC claimed on the capital good, subtract 5% for every quarter (or part of a quarter) already elapsed since the invoice date, and reverse the remaining balance.

What stays the same

Existing balances in the electronic cash ledger are not affected by the switch. GST already paid and returns already filed for the regular-registration period remain valid — the reversal only concerns the ITC embedded in stock and capital goods that will now be used to make composition-scheme (ITC-ineligible) supplies going forward.

Switching back to regular registration later

The reverse move — from composition back to regular — is more favourable: on withdrawal from composition (voluntary or forced by crossing the threshold), the taxpayer is entitled to claim ITC on stock held on the day immediately preceding the date from which regular tax liability applies, by filing Form GST ITC-01, subject to the usual credit-eligibility conditions and time limits.

Frequently Asked Questions

What if I miss the 60-day deadline to file ITC-03?
The obligation to reverse the credit does not disappear, and late filing can attract interest and potential scrutiny during a departmental review. There is no indefinite grace period built into the rule, so this should be tracked as a hard compliance deadline once CMP-02 is filed.
Does the ITC-03 reversal apply to credit on services, or only goods?
It applies to input tax credit on inputs in stock, inputs contained in semi-finished/finished goods, and capital goods. Credit already utilised for services rendered before the switch (and not embedded in unsold stock) is not separately clawed back in the same way, since it relates to supplies already completed under the regular scheme.
Can I switch to composition mid-year if I just crossed into eligibility?
The composition option generally takes effect from the start of a financial year for existing registrants filing CMP-02 in advance. A newly registering business can opt in from the effective date of registration itself via REG-01. Existing regular taxpayers generally cannot switch mid-year outside this window except in specific transitional circumstances the rules provide for.
