Key Tax & GST Compliance Dates Every Business Should Track

Staying ahead of statutory deadlines is the simplest way to avoid interest, late fees and penalties. Here is a practical overview of the recurring compliance dates most businesses need to track.

Monthly GST returns

Most registered taxpayers file GSTR-1 and GSTR-3B each month. Missing these attracts late fees and can block input tax credit for your customers. Set an internal cut-off a few days before the due date so reconciliations are complete.

TDS deposits and returns

Tax deducted at source must be deposited by the 7th of the following month, with quarterly TDS returns thereafter. Late deposit carries interest, so build TDS into your monthly payment routine.

Advance tax

Businesses and professionals with a tax liability generally pay advance tax in four instalments across the financial year. Estimating income early avoids a large year-end outflow and interest under sections 234B/234C.

Annual filings

The financial year closes with income-tax returns, tax audit (where applicable), the GST annual return (GSTR-9) and reconciliation statement (GSTR-9C) for larger taxpayers, plus ROC filings for companies and LLPs.
