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
Which GSP do you use?
ThynkTax is GSP-agnostic - we support MasterGST and GSTHero out of the box. You can bring your own GSP credentials from Settings.
Is e-invoicing supported?
Yes. We integrate with the NIC IRP to generate IRNs and QR codes in-line with GSTR-1 preparation.
Can I bulk-file for multiple GSTINs?
Yes. A single CA firm can file for hundreds of clients and GSTINs - bulk approve and bulk submit.
