Old vs new regime with age-aware slabs, surcharge, and cess.

Calculator outputs are planning estimates. Final tax depends on complete return data, eligible credits, and official updates by the tax authorities. India calculations follow the current government-notified baseline (new-regime slabs announced in Budget 2025), and US federal values follow IRS published 2025 thresholds with the 2025 OBBB-adjusted standard deduction.

How to Use the India Calculator (FY 2025-26 / AY 2026-27)

  1. Choose FY 2025-26 (AY 2026-27) and select your preferred regime option.
  2. Select your age bracket if you want old-regime precision for senior/super-senior exemption limits.
  3. Enter gross annual salary before exemptions. Add exempt allowance adjustments separately where relevant.
  4. Add other income and deduction estimates such as savings deductions, insurance, and eligible exemptions.
  5. Click Calculate Tax and compare old vs new regime output before filing.

New-regime rebate can reduce tax to zero up to eligible limits. Special-rate income may be excluded from rebate treatment.

How to Use the USA Calculator

  1. Select filing status first because it changes bracket thresholds and standard deduction.
  2. Enter gross annual income in USD and update above-the-line adjustments where applicable.
  3. Add pre-tax contributions and optional itemized deduction values if they exceed the standard deduction.
  4. Provide federal withholding already paid so refund or additional due can be estimated.
  5. Review the bracket breakdown and effective tax rate to plan payments before final return filing.

This page focuses on federal estimate logic. State taxes, credits, AMT, and special cases should be reviewed during return preparation.
