What is a "Tax Year"? The New Concept Replacing Previous & Assessment Year

Blog › Income Tax

For decades, Indian income tax used two overlapping terms — the Previous Year (when you earned) and the Assessment Year (the next year, when it was taxed). This confused millions. From FY 2026-27, the Income-tax Act, 2025 uses one term: the Tax Year.

Old vs new terminology

Concept	Old term	New term
The year you earn (1 Apr–31 Mar)	Previous Year 2026-27	Tax Year 2026-27
The year it's assessed/filed	Assessment Year 2027-28	(no separate term)

Why it matters: fewer mismatched year references = fewer errors when quoting a year in a return, notice reply or TDS statement.

🧮 Worked example

You earn freelance income between 1 April 2026 and 31 March 2027.

Old way: "Previous Year 2026-27, taxed in Assessment Year 2027-28." New way: "Tax Year 2026-27." Same income, same tax — one clear label.

👩‍💼 Expert view

When you receive any notice or Form 26AS/AIS after the switch, check whether it references a "Tax Year" or the old AY — mixing them up is the most common filing error we expect in the first year.
