About Taxzentic
Practical tax calculators and reference tools for Indian businesses, taxpayers, and professionals.
Our Mission
Taxzentic provides online tools and educational references to help people work through common tax and compliance calculations. Most tools can be used without creating an account. Results depend on the information and assumptions entered, and should be checked against current official requirements.
India's GST system, while transformative, can be complex. With multiple tax slabs, thousands of HSN/SAC codes, and strict GSTIN format requirements, even experienced professionals sometimes need a quick reference. We built these tools to be that reference.
Our Editorial & Verification Process
Meet our Editorial & Research Team →We research our tools and educational pages using primary government materials where relevant. The method, scope, and references vary by page; pages with a dated legal review show that date alongside their sources.
We use CBIC notifications, GST Council materials, legislation, and official portal guidance when reviewing applicable rates, thresholds, and rules. Check each page's references for its scope.
We use official legislation, notifications, circulars, and department guidance as primary references where applicable. A source citation does not mean that a tool determines your legal position.
We review content when changes or reader reports come to our attention. A review date is shown only where one has been recorded for that page.
What We Offer
The site includes a growing set of GST, income-tax, and business compliance tools, from basic calculations to reference and reconciliation utilities.

The site is designed to adapt to phone, tablet, and desktop screens.
We aim for readable interfaces, keyboard support, and clear labels, and welcome reports about barriers.
