About TaxGamma
TaxGamma publishes GST rate references and calculators for India. The aim is narrow and deliberate: tell you the current rate for a specific thing, show the arithmetic, and get out of the way.
Why the site exists
The GST Council withdrew the 12% and 28% slabs on 22 September 2025, leaving 0%, 5%, 18% and 40%, plus the special 3% rate on gold and silver and a residual 12% on building bricks and earthen roofing tiles. It was the largest restructuring since GST launched in 2017, and it left a great deal of published material wrong. Rate pages that were accurate in August 2025 became misleading overnight, and many were never updated.
That is the gap this site is built for. Every rate here has been checked against the position after the September 2025 reform, and each page carries the date it was last verified so you can judge for yourself whether it is current.
How a rate page is made
Each page follows the same process, and it is worth being plain about what that involves.
- The rate and classification are researched against current sources, with preference given to CBIC notifications and practitioner commentary that cites a specific notification over general summaries.
- The page is written by the TaxGamma editorial team.
- It is reviewed by CA Amit Tripathi for technical accuracy before publication.
- Calculator logic and worked examples are checked arithmetically, not assumed.
- Where sources genuinely conflict, the page says so rather than picking one and projecting false confidence.
Current over comprehensive
A correct rate for thirty categories beats a stale rate for four hundred. We would rather cover less and keep it right.
The arithmetic is shown
Every rate page includes a worked example and a calculator, so you can check the number rather than trust it.
Conflicts are disclosed
Where reputable sources disagree, the page says so. Manufactured certainty is worse than an honest caveat.
Corrections are dated
When we get something wrong we fix it on the page and date the fix, rather than editing silently.
What this site is not
It is a reference, not an advisor. The pages describe published rates in general terms. They cannot know the facts of your transaction, and GST frequently turns on exactly those facts: whether a supply is composite or mixed, whether premises are specified, whether a contract is pure labour or a works contract. For anything with money attached, confirm the position with a professional who can see your paperwork.
Independence. TaxGamma does not accept payment for coverage, and no rate page is influenced by any commercial relationship. If that ever changes, it will be disclosed on the page it affects.
Who runs it
TaxGamma is an independent publisher based in New Delhi. It is not part of an accounting firm, a filing service or a software company, and it does not sell anything — which is deliberate, because it means no page here has a product to push behind it.
It started from a practical annoyance. After the September 2025 reforms, looking up a GST rate meant wading through pages that were confidently out of date, or that answered a different question than the one asked. The fix was not more content. It was fewer pages, each one checked against the notification it depends on, each one carrying the date it was last verified so you can decide how much to trust it.
The site is run by a small editorial team, with rate pages reviewed by a Chartered Accountant before publication. Our full process, including how we handle conflicting sources and corrections, is set out in the editorial policy.
