Price before or after tax
In GST, select exclusive to add tax to a base price and inclusive to extract tax already included. Removing tax uses division by one plus the rate. The tool does not classify a product or identify its current rate.

Tax Calculators for GST, Salary Income and HRA
Choose the tax base before entering a rate. GST and Sales Tax work with a transaction price; Income Tax works with annual salary; HRA compares annual salary, rent and allowance amounts.

How to choose and compare
Annual salary and deductions
Income Tax shows a tax year 2026–27 salary estimate with old and new regime choices. It assumes a resident individual below 60 and omits surcharge and marginal relief. HRA is a separate exemption estimate; do not claim it automatically under every regime.
Verify before relying on an estimate
Check the effective rule date, eligibility and supporting documents. Do not enter the standard deduction again as an old-regime deduction: the salary tax calculator already subtracts it. A result is not a tax return or proof of exemption.
