What is CMP-08?


FORM CMP-08 is a tax return form under the Goods and Services Tax (GST) regime in India. It is a monthly self-declaration form that a taxpayer has to file if they have opted for the Composition Scheme under GST.

Under the Composition Scheme, small taxpayers with an annual turnover of up to Rs. 1.5 crore can pay GST at a reduced rate and file returns on a quarterly basis instead of monthly. Form CMP-08 is used by taxpayers to pay the GST liability for the month, along with the relevant details of the transactions carried out during the month.

The form needs to be filed by the 18th of the next month. For example, the GST liability for January needs to be paid and the form needs to be filed by the 18th of February.

It’s important to note that the information provided in Form CMP-08 should be accurate and in compliance with GST laws and regulations. Any discrepancies or errors in the form can lead to penalties and interest charges.

GST CMP-08 is the statement that dealers registered under the Composition Scheme use to report their self-assessed tax liability. It provides information on taxes owed for sales and purchases (subject to the Reverse Charge Mechanism) and has replaced Form GSTR-4.

Composite Dealers are required to file CMP-08 returns every quarter through the GST Portal. They can calculate their tax liability and make payments online. If no tax is owed during the quarter, a Nil return must be submitted.

I have recently registered a Private Limited firm and was looking for a CA to take care of the filings, Startup India Certificate, and other formalities. I have received emails from legal Suvidha and a few others. I tried talking to them all. But, Mr. Mayank from Legal Suvidha was very impressive and was patient enough, prompt to answer all the queries. He has a very professional team and after the initial formalities, I started interacting with the team. It's not even 2 weeks but I really feel overwhelmed by their service and professionalism. I received my startup India certificate yesterday and my filings have been done promptly. The team at legal suvidha Ms. Nidhi, Ms. Priyanka, Ms. Koshika, and Ms. Saloni all show the same professionalism and are readily available to take care of the official filings and stuff. Overall a great experience till now and looking forward to a great journey!
