Mastering the CMP-08 Filing Due Date: A Comprehensive Guide for GST Composition Dealers

Navigating the GST Composition Scheme: Why CMP-08 Compliance Matters

The Goods and Services Tax (GST) Composition Scheme is a lifeline for small businesses, offering simplified compliance and lower tax rates. However, this simplification comes with specific responsibilities, chief among them being the timely submission of the Statement for Payment of Self-Assessed Tax, known as Form CMP-08. Missing the crucial CMP-08 filing due date can lead to penalties and complicate your annual compliance.

For composition dealers, understanding the quarterly payment cycle and the associated deadlines is paramount to maintaining good standing with the tax authorities. This comprehensive guide breaks down the requirements, walks you through the filing process, and ensures you never miss the CMP-08 filing due date again.

Opting for the Composition Scheme, as explained in our detailed guide on who is eligible for the GST Composition Scheme, means fewer returns but strict adherence to the payment schedule outlined in CMP-08.

Understanding the CMP-08 Filing Due Date Schedule

Unlike regular GST registrants who file monthly or quarterly returns (GSTR-1 and GSTR-3B), Composition Scheme dealers only need to file two mandatory forms throughout the year: the quarterly statement CMP-08 and the annual return GSTR-4. The CMP-08 serves as the mechanism for depositing the tax liability for the quarter.

The most critical piece of information for any composition dealer is the specific deadline for submitting this statement. The CMP-08 filing due date is set for the 18th day of the month succeeding the end of the quarter.

It is important to note that the date is strictly the 18th, regardless of weekends or public holidays, unless the government issues a specific extension notification. Tax professionals often advise clients to complete their calculations and filing well ahead of the deadline to avoid last-minute technical glitches.

Key Features of the CMP-08 Filing

Form CMP-08 is not a full return; it is merely a statement of tax payment. It requires the composition dealer to declare the aggregate turnover for the quarter and the tax payable under the relevant composition rate (e.g., 1% for manufacturers and traders, 6% for service providers/mixed suppliers). The tax is calculated on the turnover of outward supplies, including exempt supplies.

• Self-Assessment: The tax liability must be self-assessed and paid before or along with the filing of CMP-08.
• Zero Filing: Even if the turnover during the quarter is zero, the dealer must still file a ‘Nil’ CMP-08 statement by the CMP-08 filing due date.
• No Input Tax Credit (ITC): Composition dealers are restricted from claiming ITC on purchases.

Step-by-Step Guide to Filing CMP-08

Filing the CMP-08 is a straightforward process completed entirely online through the official GST portal. Ensuring accuracy in turnover reporting is crucial, as any discrepancy can trigger scrutiny later, especially when reconciling with the annual GSTR-4 return.

Here is the practical workflow for timely submission:

1. Log In: Access the official GST portal using your credentials.
2. Navigate to Services: Go to ‘Services’ > ‘Returns’ > ‘Statements of Quarterly Return’.
3. Select Period: Choose the financial year and the specific tax period (quarter) for which you are filing.
4. Initiate Filing: Click on ‘PREPARE ONLINE’ for Form CMP-08.
5. Enter Details: Input the aggregate turnover for the quarter and the tax payable. The form calculates the breakup of CGST, SGST/UTGST, and Cess automatically based on the rate applicable to your business type.
6. Generate Challan: If a tax liability exists, generate the challan (PMT-06) and make the payment using Net Banking, Debit/Credit Card, or Over-the-Counter (OTC) deposit. The payment must be completed before proceeding to the final steps.
7. Verify and Submit: Review the filled details carefully. Verify the form using a Digital Signature Certificate (DSC) or Electronic Verification Code (EVC).
8. Confirmation: Once submitted, an Application Reference Number (ARN) will be generated, confirming the successful filing of your CMP-08 statement.

For businesses handling their compliance in-house, mastering the GST Return Filing process, starting with accurate CMP-08 submissions, is vital for long-term operational peace.

Penalties and Consequences for Missing the CMP-08 Filing Due Date

Adherence to the CMP-08 filing due date is not optional. Failure to file the quarterly statement by the 18th of the succeeding month attracts statutory penalties. These penalties are designed to encourage timely compliance and ensure the government receives its tax revenue promptly.

Late Fee Structure

The late fee for delayed filing of CMP-08 is currently ₹50 per day of delay. This is broken down as ₹25 for CGST and ₹25 for SGST/UTGST. The maximum late fee is capped, but even small daily penalties can accumulate significantly, especially for small businesses operating on tight margins.

“Timeliness in GST compliance is crucial. Even minor delays in filing CMP-08 can result in accumulated late fees that severely impact the cash flow intended to be protected by the Composition Scheme.”

Furthermore, if you fail to file CMP-08 for two consecutive quarters, the GST officer has the authority to initiate proceedings to cancel your registration under the Composition Scheme, forcing you into the more complex regular scheme.

Reconciling Quarterly Payments with the Annual GSTR-4 Return

While CMP-08 ensures quarterly tax payment, the comprehensive details of the year’s transactions are reported in the annual return, GSTR-4. The GSTR-4 is due by April 30th following the end of the financial year (e.g., GSTR-4 for FY 2024-25 is due April 30, 2026).

The total tax paid through the four quarterly CMP-08 statements must match the total tax liability declared in the final GSTR-4. This reconciliation is vital for compliance and prevents discrepancies. If the CMP-08 statements are filed accurately and on time, the GSTR-4 preparation becomes significantly simpler.

Ensuring Accuracy in Turnover Reporting

Accuracy begins with meticulous bookkeeping. Composition dealers must ensure that their calculation of ‘aggregate turnover’ for the CMP-08 period includes all taxable, exempt, and non-GST outward supplies (excluding inward supplies on which tax is payable under reverse charge).

The GST framework mandates transparency, emphasizing that proper records must be maintained to substantiate the turnover reported in CMP-08. For detailed guidelines on maintaining tax records, reference should be made to the official guidelines published by the Central Board of Indirect Taxes and Customs (CBIC) (CBIC Official Website).

Comparison: Composition Scheme vs. Regular Scheme Filing Burden

One of the main appeals of the Composition Scheme is the reduced filing frequency compared to the Regular Scheme. Visualizing this difference highlights the efficiency gained by meeting the CMP-08 filing due date.

This comparison underscores that while the tax rate is low and the forms are few, the few deadlines that exist, particularly the CMP-08 filing due date, must be strictly observed. Missing a single deadline negates much of the compliance simplicity the scheme offers.

Strategic Tips for Meeting Every CMP-08 Deadline

To ensure continuous compliance and avoid late fees, small businesses should implement robust internal procedures centered around the quarterly cycle:

1. Set Quarterly Reminders: Mark the 18th of July, October, January, and April as immovable deadlines in your accounting calendar.
2. Reconcile Turnover Monthly: Do not wait until the last week of the deadline month. Calculate your monthly turnover and potential tax liability throughout the quarter.
3. Utilize the GST Portal Features: The portal provides tools and ledgers that help track previous payments and turnover, simplifying the current quarter’s calculation.
4. Maintain Separate Books: Keep records distinct for outward supplies, especially if you have a mix of taxable and exempt supplies, as required under GST law (GST Portal India).

By treating the CMP-08 due date with the seriousness it deserves, composition dealers can leverage the full benefits of the scheme—simplicity, reduced tax burden, and freedom from complex monthly reporting.

Conclusion

The GST Composition Scheme provides a streamlined compliance path for smaller taxpayers, but success hinges entirely on timely and accurate filing. The quarterly CMP-08 filing due date (the 18th of the month following the quarter) is a non-negotiable deadline for depositing the tax liability. By implementing proactive tracking and utilizing the resources available on the GST portal, composition dealers can easily avoid penalties, maintain their scheme eligibility, and focus on growing their business rather than managing complex tax litigation. Prioritize accuracy and timeliness to maximize the benefits of the Composition Scheme.
