Quick Answer – Which Tax Regime Is Better for AY 2026–27?

Why You Must Compare Old vs New Tax Regime Before Filing ITR
Choosing between the old vs new tax regime is not just a formality — it directly impacts your final tax liability. Many taxpayers assume the new regime is always better due to lower tax rates, but in reality, the correct choice depends on your income structure, deductions, and investments.
Under the old regime, taxpayers can claim deductions like Section 80C, 80D, HRA, and home loan interest, which can significantly reduce taxable income. On the other hand, the new regime offers lower slab rates but removes most deductions, making it beneficial only when deductions are minimal.
This is why using an old vs new tax regime calculator AY 2026–27 is essential. It helps you compare both regimes side-by-side and ensures that you don’t end up paying higher tax due to wrong selection.
