Frequently asked questions
What does the old versus new regime comparison show?
It estimates income tax under both regimes using the income, deductions and tax-year options entered, then compares the estimated liability.
Which tax year should I select?
Select the year that applies to your income and filing. Tax slabs, deductions and other rules can change between years.
Should I choose a regime based only on this result?
Treat the result as an estimate. Eligibility, income types, rebates, surcharge, cess and deductions can affect the final calculation; verify current official rules before filing.
