About GST365

We make India's most complex tax feel simple.

Make India's most complex indirect tax feel simple — so every taxpayer, from a single proprietor to a 60-client practice, can get compliance right without fear.

Our story

Born from a notice-heavy, invoice-matched reality.

GST365 was born from a simple observation: since 2017, GST has quietly become invoice-matching-driven and notice-heavy. Input tax credit is now hostage to your suppliers' filings. Automated, time-boxed notices land in days, not months. And the rules change constantly — GST 2.0 rewrote the rate slabs overnight.

The tools that exist mostly digitised the old paperwork. We wanted something that actually understands the law — a co-pilot that reads a notice, knows the section, computes the deadline, and drafts a cited reply. India-first, AI-first, and built by people who have sat on both sides of the table.

So we brought together former GST department officials, senior Chartered Accountants and product engineers to build one platform for the entire compliance journey — advisory to answer.

GST365 Technologies Pvt. Ltd. builds one platform for the entire compliance journey — advisory to answer — from Bengaluru, Karnataka 560103.

What we stand for

Principles that keep GST365 defensible.

Tax is regulated territory. These are the non-negotiables baked into every workflow, every answer and every line of code.

India-first, always

Not a global tax suite with an India tab. Every workflow is built for the CGST/IGST Acts, GSTN forms and the way Indian businesses actually file.

Cited, never fabricated

Tax is no place to guess. Every answer is anchored to the section, notification and case law — with a law-as-on-date stamp you can defend.

Co-pilot, not autopilot

You stay in command. GST365 brings structured, cited drafts and reconciliations; a human reviews and signs off before anything is filed.

Trust by design

Bank-grade security, a full audit log for every action, and a promise: your financial data is never used to train third-party models.

Built by insiders

Both sides of the table, on one team.

Former GST department officials, senior Chartered Accountants and product engineers — so the platform understands the law, the litigation and the officer's checklist.

GC

Former GST Policy Advisor

Two decades in indirect-tax policy and administration, with a front-row seat to how GST rules are drafted and enforced.

CA

Senior Chartered Accountant

A GST litigation specialist who has drafted hundreds of replies from ASMT-11 to APL-01 across sectors.

AU

Ex-Departmental Auditor

Ran departmental audits and scrutiny under Section 65 — now teaches the platform what officers actually look for.

AI

Principal AI Engineer

Builds the citation-grounded retrieval and matching engines that keep every answer traceable to primary law.

Note: team members are described by their professional background. Any public endorsement of a specific ex-GST-Council or departmental association is indicative and subject to confirmation before it is named publicly.

How we got here

A timeline shaped by the law itself.

Every milestone below is a real inflection point in India's GST regime — and a reason GST365 exists.

  1. 2017

    GST goes live

    One Nation, One Tax. The problem we'd eventually build for is born, on 1 July 2017.

    01
  2. 2022

    ITC gets locked to 2B

    Section 16(2)(aa) makes GSTR-2B the law for credit — reconciliation becomes non-negotiable.

    02
  3. 2024

    IMS + Section 74A

    The Invoice Management System goes live and a unified demand regime arrives. The team forms around the notice problem.

    03
  4. 2025

    GST365 launches

    GST 2.0 rewrites the slabs. GST365 ships the advisory-to-answer platform with native desktop apps.

Security & trust

Bank-grade by default, Indian by residency.

Your financial data is some of the most sensitive you hold. We treat it that way — encrypted end to end, audited on every action, and never used to train third-party models.

Encryption in transit (TLS 1.3) and at rest (AES-256)
Role-based access control & SSO for teams
