Early-stage startups should set up GST cleanly from day one.
Do startups need GST registration?
Registration becomes mandatory once your aggregate annual turnover crosses ₹40 lakh for goods or ₹20 lakh for services (₹20 lakh and ₹10 lakh respectively in the special-category states). You can also register voluntarily below those limits to claim input tax credit and sell to GST-registered buyers.
Many startups register voluntarily before they hit the threshold because their clients or marketplaces ask for a GSTIN, and because it unlocks input tax credit on their own costs.
Which GST returns startups file
- GSTR-1 for your outward supplies (sales), monthly or quarterly.
- GSTR-3B summary return with your tax payment.
- GSTR-9 annual return once turnover crosses the applicable limit.
- A nil return in any period with no activity — still mandatory.
The composition scheme can simplify this if you qualify. Rates change at GST Council meetings, so always confirm the current figure for your exact HSN or SAC code on the CBIC rate finder or the GST portal before you print it on an invoice.
GST tips specific to startups

Frequently asked questions
Is GST registration mandatory for startups in India?
It becomes mandatory above ₹40 lakh turnover for goods or ₹20 lakh for services (half that in special-category states), or immediately if you sell through an e-commerce operator or across state lines in taxable goods. Below that you may register voluntarily.
Which GST return should startups file?
Most file GSTR-1 and GSTR-3B (monthly or quarterly under QRMP), plus GSTR-9 annually once the turnover limit applies. HelloBooks files GSTR-1 and GSTR-3B free.
How can startups reduce GST compliance work?
Use GST accounting software that raises compliant invoices and auto-fills your returns. HelloBooks does this free for Indian businesses, with GSTR-2B reconciliation built in.
