Late fees on GSTR-1 since 2017:

• GSTR-1 late fee: Rs 50 per day (Rs 20 for nil), capped at Rs 2,000 per return for turnover up to Rs 1.5 crore (from June 2021, Notf 20/2021-CT). For returns before June 2021, earlier caps applied (Rs 10,000 per return, with waivers for July 2017 to November 2019 GSTR-1s under Notf 4/2018 and later amnesty).

• For B2C-only taxpayers, GSTR-1 is still mandatory (with B2C summaries).

• The late fee for GSTR-1 is computed and paid when filing (the portal shows it). For older periods (2017-18 to 2019-20), check the amnesty waivers (Notf 74/2018, 76/2018 waived GSTR-1 late fees for July 2017 to September 2018 if filed by certain dates; later waivers for 2019-20). Those windows have passed, but past waivers may cover old returns filed within them.

• Also, the 3-year bar on filing returns (from 2025) may prevent filing very old GSTR-1s now.
