- Q4 (prior FY) TDS returns & Form 16 issue
- GSTR-1 / GSTR-3B monthly filings
- ITR filing due (31 Jul, non-audit)
- Second advance-tax instalment (45% by 15 Sep)
- Q1 TDS return (Form 24Q/26Q)
- Tax-audit & report season begins
- Tax-audit ITR due (31 Oct)
- Third advance-tax instalment (75% by 15 Dec)
- Q2 TDS return; GST annual return prep
- Belated / revised return window
- Final advance-tax instalment (100% by 15 Mar)
- Year-end tax-saving investments (80C etc.)
- Q3 TDS return; books close on 31 Mar
- GST reconciliation before year end
How the finder works
Given just a month and a calendar year, the tool maps the date onto India's April–March financial year and then to the right quarter and assessment year.
Read the month
Months April (4) to December (12) belong to the FY that starts in the selected calendar year.
Roll back Jan–Mar
Months January (1) to March (3) belong to the FY that started the previous calendar year, so the start year is year − 1.
Label the FY
The FY label is start-year to the next year, e.g. 2026-27. The quarter is Q1 Apr–Jun, Q2 Jul–Sep, Q3 Oct–Dec, Q4 Jan–Mar.
Derive the AY
The assessment year is always the FY plus one — income of FY 2026-27 is assessed in AY 2027-28.
Key terms explained
Financial Year (FY)
The 12-month period the government uses for accounting and taxing income — 1 April to 31 March in India. Income you earn in this window is a single financial year, e.g. FY 2026-27.
Assessment Year (AY)
The year after the FY, when that income is assessed and the return is filed. It is always FY + 1 — income of FY 2026-27 is filed in AY 2027-28.
Calendar year vs FY
A calendar year is plain January–December. The FY is offset — so a date in Jan–Mar falls in a financial year that already began the previous calendar year (Q4). For example, March 2027 belongs to FY 2026-27.
Quarter & why April
Each FY splits into four quarters — Q1 Apr–Jun, Q2 Jul–Sep, Q3 Oct–Dec, Q4 Jan–Mar. India's April start dates to the colonial-era Government of India accounting cycle, and quarters drive GST, TDS and advance-tax deadlines.
Questions people ask
Short answers on Financial Year & Quarter Finder. Tap a question to open it.
01What is the Indian financial year?
It runs from 1 April to 31 March. So FY 2026-27 begins on 1 April 2026 and ends on 31 March 2027.
02What is the difference between financial year and assessment year?
The financial year is when you earn the income; the assessment year is the following year in which you file the return and the income is assessed. Income of FY 2026-27 is assessed in AY 2027-28.
03How are the quarters numbered?
Q1 is April to June, Q2 July to September, Q3 October to December and Q4 January to March. TDS returns, advance tax and GST quarterly filings all follow this numbering, not the calendar quarter.
04Why does the calendar quarter not match?
Many global systems use the calendar year, where Q1 is January to March. Indian statutory filings are based on the April-to-March year, so the same months carry different quarter numbers — a common source of confusion in reporting.
05Which year do I quote when paying tax?
Advance tax and self-assessment tax challans are tagged to the assessment year, while TDS challans are tagged to the financial year and quarter. Quoting the wrong year is one of the most common reasons a credit does not show in 26AS.
