GST Return Filing for Startups
Funded startups face GST filing complexity beyond their team's bandwidth — foreign RCM on AWS/Slack/Notion, ESOP GST implications, multi-state GSTINs from Amazon FBA/warehouses, and monthly ITC reconciliation across 30+ vendors.
- Startups filers: GSTR-1 by the 10th, GSTR-3B by the 20th, GSTR-9 by 31 December — miss and pay ₹50/day + 18% interest.
- ITC eligibility for Startups is dictated by GSTR-2B; blocked credits under Section 17(5) must be reversed monthly.
- Correct HSN/SAC and place-of-supply are the two errors Startups businesses lose most ITC on.
- E-invoicing is mandatory above ₹5 Cr turnover; missing IRN blocks buyer's ITC.
- Taxpex files 3 days early, CA-signs every return and defends notices on filed periods free of charge.
