Income Tax Calendar For FY 2026-27:Tracking income tax deadlines in FY 2026-27 is more than just remembering when to file your ITR. The new financial year brings a detailed schedule of TDS deposits, advance tax instalments, compliance filings, and reporting requirements that taxpayers must follow closely to avoid penalties and interest charges.
Here is a simplified, month-wise breakdown of the most important income tax deadlines you need to remember this year.
April To June: Financial Year Begins With Key Compliance Tasks
The financial year opens with multiple reporting and documentation requirements. By April 14, taxpayers must ensure TDS certificates are issued for transactions such as property purchases, rent payments, contractor fees, and virtual digital assets.
By April 30, non-government deductors are required to deposit TDS and TCS collected in March. Individuals eligible for lower or zero TDS can submit Form 15G or 15H. Pension fund investment intimation also falls within this timeline.
May continues with routine compliance. TDS and TCS for April must be deposited by May 7, while employers must issue Form 16 and Form 16A by mid-May. High-value financial transactions must be reported through Form 61A by May 31, along with other disclosures, including Form 61B and Form 10BD.
June introduces the first advance tax deadline. Taxpayers with a liability exceeding Rs 10,000 must pay 15 per cent of their estimated tax by June 15, along with ongoing TDS compliance.
