What ships today

Every module below is in production today — used in real GSTR-1, 3B and 2B filings.

LIVE

GSTR-1 push-button filing

Stage, validate, retsave, retevcfile in one click. NIC v4 aligned: B2B / CDNR / EXP / HSN.

LIVE

GSTR-3B + ITC offset

Auto-built from GSTR-1 and post-2B ITC. Cash-vs-credit utilisation calculated for you.

LIVE

Books-vs-portal recon

Match every invoice, CN and DN against 2A and 2B. Mismatches surface in a worklist.

LIVE

IMS triage engine

Auto-accept clean inward records. Manual review for the rest. B2B / SEZ / DE / CDNR.

LIVE

Filing calendar

Every GSTIN × every period × every return — colour-keyed by live portal status.

LIVE

Live portal status

GSTR-1, 3B, 2B status pulled directly from GSTN — ARN, filing date, mode of signing.

How it works

Three steps. Zero guesswork.

STEP 01

Connect a GSTIN

Verify with GSTN, cache the session token. Trade names and counter-party details resolve automatically.

STEP 02

Reconcile & triage

Books-vs-2B match every invoice, Credit Note and Debit Note. IMS auto-accepts the clean records.

STEP 03

File in one click

GSTR-1 push-button. GSTR-3B with ITC offset. Filing status streams back live from the portal.

Backed by experts

Software does the work. Qualified CAs stand behind it.

GSTFiler is built alongside a panel of practising Chartered Accountants and Certified GST Experts. They draft the tax logic, sign off on the validation rules, and update the engine every time CBIC issues a circular.

Tax logic

Rules written by CAs

ITC eligibility, RCM, place-of-supply, SEZ — every classification rule is drafted and signed off by practising CAs.

Validation

CA-grade pre-submit checks

Cross-section reconciliation, HSN-rate consistency, IRN linkage, taxable-value rounding — all codified.

Regulatory updates

Notifications & circulars tracked

When CBIC issues a circular or changes a rate, the rule book updates here first.

Who it’s for
