Which Year Does This Income Tax Calculator Cover?

The calculator above is set for FY 2026-27, which is Tax Year 2026-27 under the Income-tax Act, 2025. It compares the old and new regimes for that tax year using the slabs shown on this page, including the 4% health and education cess. Use the sections below if you are looking for an earlier year, and always apply the slabs and rules that were in force for that particular tax year rather than the current year’s figures.

Income Tax Calculator FY 2024-25

FY 2024-25 was an earlier income year under the previous framework, assessed in the following assessment year. If you need an estimate for FY 2024-25, confirm the slabs, deductions and rebate rules that applied to that year before using any figure, because they differ from the FY 2026-27 settings used by the calculator above.

Income Tax Calculator FY 2025-26

FY 2025-26 is the income year immediately before the calculator’s current FY 2026-27 setting. For FY 2025-26, again check the slabs and deduction rules in force for that tax year, and do not simply carry over the FY 2026-27 slabs, standard deduction or rebate shown above.

Income Tax Calculator AY 2024-25 (Historical Note)

AY 2024-25 is a historical label from the Income-tax Act, 1961 framework: it was the assessment year for income earned in FY 2023-24. Under the Income-tax Act, 2025, the old terms ‘previous year’ and ‘assessment year’ are replaced by the single concept of ‘tax year’, so for current calculations use the tax year in which the income was earned.
