Who uses CMP-08
Composition taxpayers use CMP-08 to furnish the quarterly statement and discharge the applicable tax liability for the period. It should reconcile to the taxpayer’s books and composition status.
Quarterly checks
- Confirm the taxpayer remained eligible for composition during the period.
- Reconcile turnover and taxable amounts.
- Review reverse-charge liabilities.
- Verify payment through the electronic cash ledger.
Annual linkage
Quarterly CMP-08 records should remain consistent with the annual return and books. Differences should be explained rather than carried forward without review.
Practical preparation workflow
- Confirm that GST CMP-08 – Composition Taxpayer Quarterly Payment Statement is the correct filing, statement, application or compliance route for the entity and the relevant period.
- Reconcile the underlying books, registers, declarations, challans, approvals or source records before entering data into the portal.
- Check names, registration numbers, dates, reporting period and attachments against the master records. Avoid copying an older filing without checking whether the facts or portal fields have changed.
- Preview the completed filing before submission and retain the acknowledgement, payment/challan record and a complete copy of what was filed.
Records to reconcile
The exact attachment requirement depends on the facts and the current portal. As a working file, keep the following records together and reconcile them before submission:
- Quarterly turnover / outward-supply summary
- Purchase and reverse-charge records
- Electronic cash ledger / payment records
- Prior-period adjustment records where relevant
- Books and supporting invoices / vouchers
Review after filing
A successful upload does not by itself prove that every underlying compliance requirement has been satisfied. Preserve the acknowledgement and filing copy, update the organisation's compliance calendar or statutory records where relevant, and watch the portal/email for any defect, clarification, notice or status change. If a correction is required, use the current correction, amendment or reply mechanism rather than altering supporting records merely to match an earlier filing.
Current-source check
Portal fields, filing frequency, fees, due dates and administrative practice can change. Before acting, re-check the live guidance of GST Portal for the exact period and facts. This guide is designed to help organise the records and understand the filing context; it does not replace the live statutory form, portal instructions or case-specific professional review.
