Most startups register voluntarily before hitting the threshold
The commonly discussed GST threshold is Rs. 20 lakh for services and Rs. 40 lakh for goods, with state and category exceptions. Startups often still register early to issue tax invoices, sell to GST-registered customers, export services with LUT, and create investor-ready compliance records.
Situations this page is built for
- SaaS or tech startup with first enterprise client asking for GSTIN.
- Startup with foreign client payments wanting LUT for zero-rated export.

- Startup crossing Rs. 20 lakh service revenue and needing mandatory registration.
Documents required
- Company PAN and incorporation certificate.
- Registered office address proof: rent agreement, NOC and utility bill.

How to use this page safely
GST Registration for Startups can depend on financial year, entity type, turnover, location, portal status, notice dates, transaction volume, documentation quality and whether prior filings were done correctly.
Use this page as preparation guidance. Before filing, responding, registering or appealing, share exact forms, notices, portal screenshots, amounts, due dates and prior acknowledgements with a qualified professional.
A strong WorkIndex quote should clearly state scope, assumptions, documents required, expected timeline, exclusions, and whether follow-up, correction filing or notice-response support is included.
How to compare WorkIndex responses
- Ask whether the expert has handled this exact service type, industry and portal workflow before.
- Confirm whether the quote includes filing only, advisory only, or also reconciliation, correction, response drafting and follow-up.
- Prefer experts who ask for records before final pricing instead of quoting blindly.
- For urgent matters, include statutory deadline, notice/order date, current portal status and financial exposure.
- Keep acknowledgement, computation, challan, report, working papers and communication trail after completion.
Keep these ready before requesting quotes
- PAN, Aadhaar, GSTIN, TAN, DIN, CIN, LLPIN, UAN or registration number as applicable.
- Portal login access or screenshots from Income Tax, GST, MCA, EPFO, ESIC, Startup India or other relevant portals.
- Previous filings, acknowledgements, challans, certificates, orders, notices, audit reports and working papers.
- Bank statements, invoices, contracts, payroll records, books export, rent agreements, transaction reports or board/investor documents relevant to the case.
- A short written summary of what happened, what deadline exists, what help you need and whether support can be remote or must be local.
How to get better quotes faster
- Mention whether you need a one-time filing, urgent correction, registration, audit, monthly retainer, appeal, or advisory review.
- Add approximate transaction count, employee count, turnover range, number of filings/years pending, and any notice deadline so experts can size the work properly.
- For accounting and bookkeeping pages, share the software used, number of bank accounts, monthly invoice count, GST status, payroll size and whether old cleanup is needed.
- For audit and diligence pages, share the review period, location count, materiality level, report format expected and who will consume the report: founder, investor, bank, board or tax department.
- For tax and GST disputes, upload or summarise the section/form/order number, demand amount, date of service, due date and current portal status before asking for a fee quote.
