How this tax calculator works
The calculator applies slab-based tax to your taxable income, then adds 4% health and education cess. The new regime estimate uses AY 2026-27 slab bands for individuals as published by the Income Tax Department.
Formula used
Tax is calculated slab by slab. Each tax rate is applied only to the income portion that falls inside that slab. Total tax = tax before cess x 1.04.
Old regime vs new regime
The old regime generally allows more deductions and exemptions. The new regime generally has lower slab rates with fewer deductions. Which is better depends on your income structure and eligible deductions.
Important note
Use this for education and planning only. Final tax depends on your residential status, income type, deductions, rebate, surcharge, relief and current law.
