When to Opt Out of GST Composition Scheme: CMP-04 and ITC Transition Checklist

Finin2min GST Desk·June 2026·7 min readCMP-04

Many businesses outgrow composition mid-year. The risk is not the decision to exit; the risk is a messy transition where invoices, ITC, pricing and returns are not aligned from the effective date.

When exit becomes necessary

Exit should be considered when turnover crosses the applicable threshold, business starts restricted supplies, B2B customers demand ITC, inter-State outward supply becomes material, or e-commerce marketplace sales change the eligibility position. The decision should be documented before invoice behaviour changes.

CMP-04 and approval position

The GST portal guidance for withdrawal from composition levy refers to Form GST CMP-04. It also states that voluntary withdrawal is auto-approved immediately on filing, so the business must be operationally ready before submitting the application.
