Form CMP-08 Guide: GST Composition Scheme Filing

Form CMP-08 is a key quarterly return for small businesses under the GST Composition Scheme in India. It helps simplify tax compliance by allowing eligible taxpayers to declare and pay their self-assessed tax liability every quarter. Introduced in April 2019, Form CMP-08 replaced the older GSTR-4, making the process easier for small businesses with turnover up to Rs. 1.5 crore for goods or Rs. 50 lakh for services. In this guide, we’ll walk you through what Form CMP-08 is, who needs to file it, how to file it, and more, based on the latest information as of June 2025.

Form CMP-08, also known as the Composition Levy Statement-cum-Challan, is a quarterly statement for taxpayers under the GST Composition Scheme. It’s designed to help small businesses declare their tax liability and make payments without the hassle of complex GST filings. Introduced via Notification No. 20/2019 on 23rd April 2019, it replaced the quarterly GSTR-4 from FY 2019-2020.

• Purpose: Declare self-assessed tax liability and pay taxes for each quarter.
• Benefits: Simplifies compliance, reduces paperwork, and lowers tax rates (e.g., 1% for goods, 0.5% for services).

For example, a small retailer in Kolkata with a Rs. 1 crore turnover can use Form CMP-08 to pay 1% tax quarterly, avoiding monthly GST filings.

Form CMP-08 is mandatory for businesses registered under the GST Composition Scheme. Here’s who qualifies:

• Goods Suppliers: Businesses with annual turnover up to Rs. 1.5 crore (Rs. 75 lakh in special category states, except J&K and Uttarakhand).
• Service Providers: Turnover up to Rs. 50 lakh, as per Notification No. 2/2019 dated 7th March 2019.
• Exclusions:
  • Inter-state suppliers.
  • E-commerce operators, casual taxable persons, and non-resident taxpayers.
  • Suppliers of non-taxable goods like alcohol or tobacco.

Example: A local restaurant in West Bengal with a Rs. 40 lakh turnover can opt for the scheme and file Form CMP 08, but a business selling across states cannot.

Filing Form CMP-08 on time is crucial to avoid penalties. The due date is the 18th of the month following each quarter. For FY 2024-2025, the schedule is:

• Late Filing Penalty: Rs. 200/day (Rs. 100 CGST + Rs. 100 SGST), up to a maximum of Rs. 5,000.
• Non-Filing Consequence: Missing two consecutive quarters blocks e-way bill generation, requiring Form GST EWB 05 to unblock.

Example: If you miss the 18th July 2024 deadline for Q1, you’ll pay Rs. 200/day until filing, capped at Rs. 5,000.
