ITR 2026 Deadlines You Can’t Miss: Important Dates, Penalties, and Rules Simplified

With the income tax return (ITR) season approaching, taxpayers are being reminded to circle crucial filing dates to avoid penalties and ensure compliance. According to Deloitte India, the due dates for filing returns for the assessment year 2026‑27 vary by category.

For salaried individuals and pensioners filing ITR‑1 or ITR‑2, the deadline is July 31, 2026. Business and professional taxpayers not requiring audit, as well as partners of firms or LLPs not subject to audit, must file by August 31, 2026. Tax audit cases and partners of audited firms or LLPs have until October 31, 2026 to submit their returns.

Belated returns can be filed until December 31, 2026, with penalties of up to ₹5,000 for late filing. Taxpayers with income below ₹5 lakh face a reduced late‑fee of ₹1,000. Importantly, the old tax regime becomes unavailable after the due date, and the last date to revise returns is March 31, 2027.

Timely filing helps avoid last‑minute technical glitches and ensures smooth processing of refunds. With digital platforms simplifying compliance, taxpayers are encouraged to prepare documentation early and to verify Form 26AS and AIS details before submission.

ITR‑1, also called Sahaj, is designed for individuals with straightforward income sources. It applies to residents whose annual income does not exceed ₹50 lakh, and who earn mainly from salary or pension, one house property, and interest or dividends. Agricultural income is permitted up to ₹5,000.

This form cannot be used if the taxpayer has capital gains, foreign assets or income, more than one house property, or if they are a company director or hold unlisted equity shares.

ITR‑2, on the other hand, is meant for individuals and Hindu Undivided Families (HUFs) with more complex financial situations but without business or professional income. It covers all the income types allowed under ITR‑1, and additionally includes multiple house properties, capital gains from shares, mutual funds or property sales, foreign income or assets, agricultural income above ₹5,000, and winnings from lotteries or gambling.

Filing ITR‑2 is mandatory for non‑resident Indians, company directors, and those holding unlisted equity shares. Taxpayers engaged in business or professional activities must instead use ITR‑3 or ITR‑4.

ITR‑3 and ITR‑4 are both meant for individuals and Hindu Undivided Families (HUFs) who earn income from a business or profession. The difference lies in how your income is reported.

• ITR‑4 is for those who choose the presumptive taxation scheme under Sections 44AD, 44ADA, or 44AE. This scheme allows small businesses and professionals to declare income at a fixed percentage of turnover, without keeping detailed books of accounts.
• ITR‑3 is for taxpayers whose business or profession requires maintaining full books of accounts and, in many cases, undergoing a tax audit.
