Frequently Asked Questions

What is the difference between FY and AY in simple terms?

Financial Year (FY) is when you earn income, while Assessment Year (AY) is when you file taxes on that income. FY comes first, and AY follows immediately after. For income earned in FY 2025-26, you file returns in AY 2026-27.

As of December 2025, we are in Financial Year 2025-26, which started on April 1, 2025, and will end on March 31, 2026. The corresponding Assessment Year will be AY 2026-27.

No, you cannot file returns during the same Financial Year. You must wait until the Assessment Year begins. For FY 2025-26 income, filing opens on April 1, 2026 (start of AY 2026-27).

Selecting the wrong Assessment Year can cause your return to be rejected or create processing delays. Your TDS credits may not match, and refunds could get stuck. Always verify the AY matches your income year before submission.

You pay advance tax during the Financial Year when you’re earning the income. If your tax liability exceeds ₹10,000 in FY 2025-26, you must pay advance tax in quarterly installments during that same year.

India’s FY starts in April due to historical agricultural cycles and administrative convenience. This timing aligns with the harvest season and allows better budget planning by the government.

No, the previous year refers to the Financial Year when income was earned. Assessment Year is the following year when that income gets assessed. For tax purposes, “previous year” and “Financial Year” mean the same thing.

October 31, 2026. However, the government may extend these dates, so check official notifications.

No, FY and AY cannot overlap for tax filing purposes. They are consecutive 12-month periods. However, advance tax paid in FY gets adjusted against the final tax liability calculated in AY.

Simple rule: Add 1 to your income year. Income in FY 2025-26 means file in AY 2026-27. The Assessment Year is always one year ahead of the Financial Year.

Have you ever felt confused while filing tax returns about Financial Year and Assessment Year? Whether you’re submitting investment proofs at work or filing business taxes, these terms appear everywhere. Many taxpayers struggle to understand the difference between Financial Year (वित्तीय वर्ष) and Assessment Year (निर्धारण वर्ष).

This guide breaks down both concepts in simple terms. You’ll learn exactly when each year applies and why it matters for your taxes.

What is the Financial Year (FY)?

The Financial Year in India runs from April 1st to March 31st. This is when you earn your salary or run your business operations. For instance, FY 2025-2026 means the period starting April 1, 2025, and ending March 31, 2026.

Think of FY as your earning period. All income you receive during these 12 months gets recorded under this year. This applies to everyone – employees, businesses, freelancers, and trusts.

What is the Assessment Year (AY)?

Assessment Year follows right after the Financial Year. If you earned income in FY 2025-2026, the Assessment Year becomes AY 2026-2027. It starts on April 1, 2026, and ends on March 31, 2027.

During AY, the government reviews your previous year’s income. You file tax returns and clear any pending tax payments. Tax authorities also process refunds if you’ve paid extra taxes.

Key Differences Between Financial Year and Assessment Year

FY represents your income earning period. AY is when you report that income to tax authorities. For example, money earned in FY 2025-26 gets assessed in AY 2026-27.

The Financial Year tracks business transactions and salary credits. The Assessment Year handles tax filing, audits, and refund processing. Both years run for 12 months but serve different purposes.
