Tax Year labels vs assessment year on older forms

Same period, two naming habits

FinanceChacha copy for the current rules uses Tax Year 2026-27 (also written as FY 2026-27). Older forms, habits, and search queries still say assessment year 2027-28 for the year when that income is assessed. They point at the same span: 1 April 2026 to 31 March 2027.

If a portal asks for AY and our page says Tax Year, translate—do not assume they are different Budgets.

Why the dual label exists on this site

People still search with AY wording. Guides and the income-tax calculator mention both so the FY label in new law talk does not orphan older paperwork. When you enter numbers, what matters is that salary, HRA, and deductions belong to that financial year—not which synonym the dropdown uses.

Practical check before you file

Match Form 16’s year, AIS period, and the regime you chose for that year. If you switched jobs mid-year, both employers still sit inside the same FY/AY pair. Use the calculator for a planning compare, then file with the labels the utility expects.
