Taxation Calculators

Compare old vs. new tax regimes, work out GST, TDS and capital gains, with every calculation naming the exact section it's based on.

8 calculators

Indian tax rules change with nearly every Budget, and the same rupee can be taxed differently depending on which regime, section, or holding period applies to it. These calculators walk through the exact math: regime slabs, GST rate tiers, TDS thresholds, capital gains holding periods, so you can see which number actually applies to you, not just a rough estimate.

How to think about tax calculators

A few principles worth knowing before you run the numbers.

1Start with the regime comparison

Most salaried taxpayers should run the Income Tax Calculator under both the old and new regime before filing. The right answer depends entirely on how many deductions you actually claim, not a blanket rule either way.

2Holding period decides your capital gains rate

The same equity or property gain is taxed completely differently depending on whether you held it for a few months or a few years. Check the Capital Gains Tax Calculator's holding-period cutoffs before assuming a rate applies to you.

3TDS isn't your final tax bill

Tax deducted at source is a credit against your final liability, not the liability itself. The TDS Calculator and Income Tax Calculator work together to show whether you'd owe more or get a refund at filing time.

4Presumptive schemes trade bookkeeping for a fixed rate

Freelancers and small businesses can skip detailed books of account under Section 44AD/44ADA by declaring a fixed percentage of turnover as profit. It's worth comparing against your actual margins before opting in, since declaring less can trigger an audit.

Frequently asked questions

Straight answers to the questions we hear most about Taxation calculators.

Which tax regime should I choose?
The new regime usually wins if you claim few deductions, thanks to its higher Section 87A rebate and lower slab rates. The old regime can still come out ahead if your 80C, HRA, and other deductions add up to a large amount. The Income Tax Calculator compares both using your actual numbers.
Is GST relevant to my personal tax filing?
No, GST is a separate consumption tax on goods and services, entirely independent of your income tax return. The GST Calculator is useful for pricing and invoicing, not for filing your own income tax.
What's the difference between TDS and income tax?
TDS is tax withheld at the source of a payment (salary, interest, contract income) and deposited with the government on your behalf. It's a prepayment, credited against your final income tax liability when you file, not a separate tax.
How is capital gains tax different from regular income tax?
Capital gains, meaning profit from selling equity, property, or other assets, are taxed under their own rules (Sections 111A/112A/112), with rates and exemptions that depend on the asset type and how long you held it, separate from your regular salary-slab taxation.
Do I need to pay advance tax?
If your total tax liability for the year exceeds ₹10,000 after TDS, yes, in quarterly instalments rather than one lump sum at filing time. The Advance Tax Calculator lays out the schedule and the interest penalty for missing an instalment.
What is presumptive taxation and who can use it?
Sections 44AD (small businesses) and 44ADA (specified professionals like doctors, lawyers, and consultants) let eligible taxpayers below a turnover ceiling declare a fixed percentage of turnover as taxable profit, skipping detailed books and an audit. See the Presumptive Taxation Calculator for the exact ceilings and rates.
