The GST department issued a notification in April 2019 to introduce Form CMP-08. It replaced Form GSTR-4 i.e. GST Return for business under Composition Scheme. Form CMP-8 is applicable from FY 2019-20.

What is CMP-08 in GST?

Form CMP-08 is the statement with details of self-assessed tax payable of a dealer registered under the Composition Scheme. The form contains details of tax liability on sales and purchases (under the Reverse Charge Mechanism). This form has replaced Form GSTR-4.
The Composite Dealer needs to file CMP-08 on a quarterly basis on the GST Portal. He can calculate the tax liability and pay it online on the GST Portal. If there is no tax liability during the quarter, a Nil return should be filed.

GST Late Fees – CMP-08

If the taxpayer does not file GST CMP-08 on or before the due date, he is liable to pay a Late Fee for each day of delay.

Note: While the GST Rules mention a late fee of Rs. 200 per day in the case of CMP-08, there is no option to enter such a late fee under the option of paying tax in CMP-08. Also, the GST Portal does not auto calculate late fees in the case of CMP-08, unlike other GST Returns.

Can I pay the tax liability under CMP-08 by using Input Tax Credit?

Negative Liability Adjustment means if there is any negative entry in the return of a present quarter, it will be carried forward to the next quarter. The taxpayer can adjust this negative entry with the tax liability in the return of next quarter. Such negative entry is reflected under the column ‘Adjustment of negative liability of previous tax period’ in the CMP-08 of next quarter.

Is it mandatory for taxpayer under Composition Scheme to file CMP-08 on GST Portal?

Yes. It is mandatory for a dealer registered under Composition Scheme to file CMP-08 every quarter. Even if there is no business or no self-assessed tax liability, the Composite Dealer must file CMP-08 on the GST Portal.

      While the GST Rules mention late fee of Rs. 200 per day in case of CMP-08, there is no option to enter such late fee under the option of paying tax in CMP-08. Also, the GST Portal does not auto calculate late fee in case of CMP-08 unlike other GST Returns. Further, one of the FAQs on the help content of GST Portal, it is mentioned that there is currently no late fees on late filing of CMP-08. Thus, you can file GST CMP-08 without late fee since it is neither auto-populated nor you have an option to enter it manually.
