CMP-08 every quarter
Each quarter, a composition dealer files CMP-08 — a simple statement-cum-challan declaring turnover and paying the flat composition tax. It is due by the 18th of the month after the quarter. There is no invoice-level reporting like GSTR-1.
GSTR-4 once a year
Annually, the dealer files GSTR-4 summarising the year. Together, CMP-08 (four times) and GSTR-4 (once) are the whole compliance — markedly lighter than the monthly returns of a regular taxpayer. Late filing still attracts fees. Confirm the current forms and due dates.
A worked example
Example: a composition trader files four CMP-08 challans through the year, paying about 1% of each quarter’s turnover, then one GSTR-4 after year-end — perhaps two hours of compliance a year in total. A regular taxpayer of similar size files a dozen returns with invoice detail. The reduced workload is a real benefit for a small B2C business. Our team can handle both filings.
