How ThynkTax works
The agentic workflow - from raw data to filed return in three steps.
Connect your data
Pull from Tally, LedgrOS, your bank via Account Aggregator, or upload CSV/Excel. Everything flows into a unified client record.
Agents prepare returns
Data ingestion, validation, and reconciliation agents run in the background. Return preparation agents produce draft GSTR-1, 3B, ITR, 24Q - ready for your review.
You approve, system files
Review the draft, approve, and the Filing Agent submits to GSTN / Income Tax / TRACES / MCA. ARN / ACK stored in the audit trail.
Frequently asked questions
Do I need to know GST to use ThynkTax?
No. The agents handle the technical parts. You just provide your invoices and review a summary before filing.
What if I make a mistake?
ThynkTax runs 200+ validation checks before submitting anything to GSTN. If something looks wrong, it flags it and asks you to fix it first.
Is the free plan really free forever?
Yes. Up to 5 clients (or 1 business entity), GST module only, free forever - no credit card needed.
