Form CMP-08: Statement Filing Procedure, Due Date, Penalty and Other Pointers

In April 2019, a new tax payment process was introduced to make tax compliance easier for composition dealers. This new system introduced Form CMP-08, which replaced the previous quarterly GSTR-4 filing for composition dealers. In this blog, we'll break down what Form CMP-08 is, who should file it, the due dates, the penalties for late filing, and how to fill it out.

What is Form CMP-08?

Form CMP-08 is a special statement and challan used by composition dealers to declare the summary of their self-assessed tax payable for a specific quarter. It also serves as a means to make tax payments. A composition dealer is someone registered under the composition scheme for both goods and services. In addition to Form CMP-08, they also need to file an annual return using the revised Form GSTR-4 by April 30 following the end of the fiscal year.

Who Should File CMP-08?

Composition dealers, who have opted for the composition scheme, are required to file Form CMP-08 to deposit payments every quarter. There are two types of taxpayers who can use CMP-02 to opt into the composition scheme:

Suppliers of Goods: 

Manufacturers, and retailers with an annual aggregate turnover of up to Rs. 1.5 crore (or Rs. 75 lakhs for special category States, excluding Jammu & Kashmir and Uttarakhand) in the previous fiscal year. However, some exceptions include the manufacturers of certain goods and those making inter-state supplies or supplying non-taxable goods.

Suppliers of Services: 

Those meeting the conditions specified in Notification Number 2/2019 Central Tax (Rate) dated 7th March 2019, with an aggregate annual turnover of up to Rs. 50 lakh in the previous fiscal year.

Step 2: Fill in Tax Liability Details

In the CMP-08 form, proceed to fill in the details in Table 3.

Enter the summary figures of the value of supplies and tax payable for the three-month period.

If you're filing late and there's interest to be paid, enter that amount.

Tick the checkbox for 'File Nil GST CMP-08' if:

You had no outward supplies during the selected return period, and therefore no tax is payable.

You have no output tax liability because you had no inward supplies on which tax is payable on a reverse charge basis, including imported services.

You have no other tax liability.

After entering the details, click on 'SAVE' to save your input.

Step 3: Preview Your CMP-08

To ensure the accuracy of your input, click on 'PREVIEW DRAFT GST CMP-08.'

Review the details you've entered in the form.

Step 4: Make Payment and File CMP-08

Now, it's time to make your tax payment.

You can use the cash balance available in your electronic cash ledger for payment.

If your cash balance is insufficient, you can click on 'Create Challan' to choose either NetBanking or NEFT.

Confirm the details you've submitted by checking the declaration statement box.

Submit your CMP-08 using electronic verification code (EVC) or digital signature (DSC).

You'll receive a message confirming the filing of CMP-08 along with a unique ARN (Application Reference Number) generated by GSTN.

Additionally, you'll receive an SMS and an email on your registered mobile and email ID.

What is the due date for Filing CMP-08

Form CMP-08 should be filed quarterly, and the due date is on or before the 18th of the month following the quarter. For example, if you're filing for the January-March 2021 quarter, the due date was April 18, 2021.

What is the penalty for Late Filing of CMP-08

If you fail to submit Form CMP-08 by the due date, you will be subject to a late fee of Rs. 200 per day for each day of delay, split into Rs. 100 under CGST and Rs. 100 under SGST. This late fee accumulates to a maximum of Rs. 5,000 from the due date to the actual filing date. Additionally, if CMP-08 for two consecutive quarters goes unfiled, your e-way bill generation will be blocked. To unblock it, you'll need to apply to the jurisdictional tax official and file all pending forms for previous quarters.

How does a taxpayer fill CMP-08

Step 1: Enter GSTIN Details

Firstly, enter your GSTIN (Goods and Services Tax Identification Number).

Note: This unique identification number is essential for tax purposes.

Note: This information is crucial for tracking and verification purposes.

In conclusion, Form CMP-08 simplifies tax compliance for composition dealers. It's crucial to file it on time to avoid penalties and e-way bill issues. Keep track of your due dates, fill out the form accurately, and ensure you meet the requirements of the composition scheme.
