CMP-08 in GST: A Complete Guide for Composition Taxpayers
The Goods and Services Tax (GST) in India has a composition scheme that simplifies tax compliance for small businesses. One of the key requirements for taxpayers under this scheme is filing CMP-08. In this blog, we will discuss the purpose, eligibility, due dates, penalties, and filing process for CMP-08 in GST.
What is CMP-08 in GST?

CMP-08 is a quarterly statement-cum-challan that composition taxpayers must file to declare their tax liability and make payments to the government. It replaces the earlier GSTR-4 quarterly return. The CMP-08 form ensures that small businesses can comply with GST regulations without dealing with complex return filings.
Who Should File CMP-08?
CMP-08 is mandatory for taxpayers registered under the composition scheme, including:
● Manufacturers and traders with an annual turnover of up to 1.5 crore (75 lakh for ₹₹ select states).
● Service providers with an annual turnover of up to 50 lakh under the special ₹ composition scheme.
● Restaurants (excluding those serving alcohol) opting for the composition scheme.
Due Dates for CMP-08 Filing
CMP-08 must be filed quarterly, with the due dates being:
● For April - June: 18th July
● For July - September: 18th October
● For October - December: 18th January
● For January - March: 18th April
Failing to file CMP-08 on time can lead to penalties and interest charges.
Penalty for Late Filing
If a taxpayer does not file CMP-08 within the due date, the following penalties apply:
● Late fee of 200 per day (100 CGST + 100 SGST) until the filing is done.
● Interest at 18% per annum on the outstanding tax amount.
How to File CMP-08?
Filing CMP-08 is a simple process that can be completed through the GST portal. Follow these steps:
1. Login to the GST Portal: Visit www.gst.gov.in and log in with your credentials.
2. Navigate to CMP-08 Form: Under the ‘Services’ tab, select ‘Returns’ and then ‘File Returns.’ Choose the relevant financial year and quarter.
3. Enter Tax Liability Details: Fill in the taxable turnover and applicable tax amount for the quarter.
4. Pay Tax: Make the tax payment through net banking, NEFT, RTGS, or other available modes.

Key Points to Remember
● CMP-08 does not allow Input Tax Credit (ITC) claims.
● Composition taxpayers must file annual GSTR-4 in addition to quarterly CMP-08.
● If no sales or purchases were made in the quarter, a NIL CMP-08 must be filed.
● Composition taxpayers cannot issue tax invoices but must mention ‘composition taxable person’ on bills.
Conclusion
CMP-08 is an essential compliance requirement for businesses under the GST composition scheme. Filing it on time helps avoid penalties and ensures smooth business operations. If you are a composition taxpayer, make sure to keep track of due dates and follow the filing process carefully.
