GST law — Acts, Rules & Tools

GST law is an independent, offline reference for India's Goods and Services Tax.
It is NOT a government app — it is not affiliated with, endorsed by, or
associated with the Government of India, CBIC, GSTN, the GST Council or any
government body, and does not provide or facilitate any government service.
Official government sources are listed at the end of this description.

What it is: the bare Acts and Rules with the parts that actually make them
usable — amendment history, cross-references you can tap through, plain-English
notes, and the CBIC and GSTN material that sits alongside the statute. It is an
editorial study aid, not legal advice.

STATUTE
• CGST, IGST, UTGST and Compensation Cess Acts, plus the CGST and IGST Rules —
every section and rule, amended to date.
• Amendment history on each provision, with the wording before the change and
a "view as on any past date" mode.
• Tap any "section 16" / "rule 36" / defined term to read it in place, without
losing your spot.
• Schedules I–III and every statutory definition.

THE REST OF THE LAW
• Every CBIC circular and notification, full text.
• Every GSTN portal advisory, portal FAQ, and CBIC instruction.
• Landmark Supreme Court and High Court judgments, summarised from the orders,
by provision — with the citation and current standing.
• Landmark advance rulings (AAR / AAAR), by topic.
• Every GST Council meeting — what was announced vs what was actually notified.

TOOLS
• GST calculator, interest and late-fee, ITC reversal (Rule 42/43), refund,
appeal pre-deposit, value of supply, time and place of supply, rate-change
transition.
• GST rate finder and a 6/8-digit HSN & Customs Tariff browser with a
plain-language product classifier.
• Invoice Management System (IMS) guide — every action and its effect.
• Reverse-charge finder, blocked-credit checker, e-way-bill / e-invoice
applicability, thresholds & schemes.
• Guided pathways, document checklists, a compliance calendar, and a deadline
calculator.

BUILT FOR READING
• Works fully offline — the whole corpus is on your device.
• Light, dark, sepia and OLED themes; adjustable text size, spacing and
typeface; a distraction-free reading mode.
• Full-text search across everything, plus a find-in-document search inside any
circular or notification.
• No account, no sign-in. Every feature is unlocked. Reading screens are ad-free.

Content refreshes over the air as new notifications, circulars and advisories
are issued — no app update needed.
