What is CMP-08?
CMP-08 is a quarterly return form used to declare sales and pay tax under the GST Composition Scheme. It replaces quarterly GSTR-4 filings and is mandatory for composition taxpayers.
Now, CMP-08 is filed every quarter, and GSTR-4 is filed only once at the end of the financial year.
Who Should File CMP-08?
- Registered under GST Composition Scheme
- Annual turnover ≤ ₹1.5 crore (or ₹75 lakh in special category states)
- Service providers under the special ₹50 lakh limit composition scheme
Businesses must also ensure they meet eligibility conditions outlined under the GST regime.
Due Dates for Filing CMP-08
| Quarter | Months Covered | Due Date |
|---|---|---|
| Q1 | April to June | 18th July |
| Q2 | July to September | 18th October |
| Q3 | October to December | 18th January |
| Q4 | January to March | 18th April |
Filing on time avoids late fees and interest penalties under GST provisions.
