Tax & Money Lab — Calculate, Compare & Decide
India's practical tax and financial decision engine.
The Lab is where this site's interactive tools live: calculators, comparisons and simulators for Indian income tax, salary and CTC, NRI status and personal finance. Each one is built by a Chartered Accountant, shows the arithmetic and the section it rests on, and runs in your browser — no sign-up, and nothing you type is stored.

The rooms
Seven rooms: live tools today, and what is still being built.
Live tools open directly. Where a room is still growing, the card says what is coming and links to what already helps.
Live
Compare & Decide
Side-by-side decisions with the arithmetic shown: which regime, which structure, which route. The Tax Decision Engine will live here.
Growing
Scenario Simulators
Change one input and watch the year play out: a raise, a move abroad, a property sale, a change of regime. Tax-impact and financial scenario tools are planned here.

Source-Grounded Tax Copilot
Ask in plain words. Get the rule, the section, the source and the arithmetic.
Every legal statement it makes carries its section and an official source, and it will not guess: a question outside what has been written into it gets a plain refusal, not an invented answer. Nothing you type leaves your browser.
Questions it can answer today — tap one:
How the Lab works
Every tool answers three questions before it gives you a number.
- What does the law say?The rate, the threshold and the section are named on the page, and every threshold sits in one editable block in the tool's code, so a Budget change is a one-line update.
- What did you assume?Defaults are labelled as defaults — what the law requires, what an employer decides, what the tool assumed — so you can see where your answer would differ.
- Can you take it with you?Each calculation can be shared as a link that restores your inputs, or downloaded as a PDF with the working and the charts on it.
