GST · monthly filers
For many monthly filers, the 2026 calendar lists GSTR-1 on the 11th and GSTR-3B on the 20th. Each row is for the previous month. 11 October and 20 October 2026 have passed. The office is at 515 Trichy Road, Singanallur.
This page separates the monthly rows on the 2026 tax calendar. Preparing the returns stays on the GST filing page. Do not send the GST password in chat. Call +91 94454 38387.
GSTR-1 on the 11th is the outward-supplies return for the previous month. GSTR-3B on the 20th is the summary return and the tax payment for that same month. The 11 November row is October’s GSTR-1. The 20 November row is October’s GSTR-3B. A notified extension, or a holiday, can move a date by a day or two. Confirm the period on the GST portal before it is filed.
A month with no outward supplies can still need a return. That check is on the nil return page. Future Tax checks the period before it is filed.
A GSTIN on QRMP files quarterly, when aggregate turnover is within the limit in the notification for that year. Those rows are on the quarterly GST page. The portal shows whether the GSTIN is on QRMP. Future Tax confirms the limit before anyone opts in. The rupee limit is not copied onto this page.
GSTR-2B is usually available around the 14th. Confirm it for that period. Do not claim input-tax credit for an invoice that is absent from GSTR-2B. That check is on the GSTR-2B page. A difference between GSTR-1 and GSTR-3B is Form DRC-01B, on the DRC-01B page.
Monthly GST filing starts at ₹500 on the Coimbatore GST filing page. The quote is confirmed before filing. The first discussion is free. The length depends on the file.
