June 2026 is not just another month on the tax calendar. For salaried employees, investors, deductors, stock market intermediaries, trusts, Alternative Investment Funds and reporting entities, it brings a long list of income tax deadlines that can directly affect return filing, TDS credit matching, refund processing and compliance records.
The timing is especially important because the Income Tax Department has already enabled return filing utilities for AY 2026-27, while employees are expected to receive key salary tax documents this month. Anyone planning to file an income tax return should use June to collect documents, verify tax credits and correct mismatches before submitting the return.
Form 16 and TDS certificates make June 15 a key date
For most salaried taxpayers, June 15, 2026 is the first major date to track. Employers are required to issue Form 16 for FY 2025-26, showing salary paid, exemptions, deductions considered by the employer and tax deducted at source. This certificate is one of the most important documents for filing ITR accurately.
Taxpayers should not treat Form 16 as a formality. The TDS amount shown in Form 16 should be checked against Form 26AS and the Annual Information Statement. If there is a mismatch in salary income, tax deduction, interest income, dividend entries or other reported transactions, it is better to get it corrected before filing instead of responding to a tax notice later.
The same date is also important for Form 16A, the quarterly TDS certificate for non-salary payments for the quarter ended March 31, 2026. This matters for taxpayers who received income such as interest, commission, rent, professional fees or other payments where TDS was deducted.
Businesses, funds and trusts also face June 15 reporting requirements. These include Form 12BA for salary perquisites and forms such as 64A, 64D and 64E for business trusts, Alternative Investment Funds and securitisation trusts. The official tax calendar can be checked on the Income Tax Department tax calendar.
June 7, June 29 and June 30 deadlines taxpayers should track
The month begins with a market-linked compliance deadline. By June 7, 2026, Securities Transaction Tax and Commodities Transaction Tax collected for May 2026 must be deposited. While this mainly applies to collecting entities and intermediaries, investors should still keep their transaction statements ready because these records often become relevant while reporting capital gains in ITR.
Another deadline falls on June 29, 2026. Form 3CEK must be furnished by eligible investment funds, while Form 49D applies to Indian concerns required to provide information and documents under Section 285A. These are not routine filings for every taxpayer, but they matter for specified investment and cross-border reporting structures.
The heaviest compliance load arrives on June 30, 2026. Recognised stock exchanges and mutual funds must file annual returns related to securities transaction tax for FY 2025-26. Entities dealing with taxable commodities transactions must also complete the annual commodities transaction tax return.
Several other forms are due on the same day, including Form 10-IJ, Form 10-IL, Form 26QAA, Form 3AF, Form 64B, Form 64C and Form 64F. These cover accountant certificates, quarterly non-deduction reporting by banking companies, preliminary expenses statements, and income distribution statements for business trusts, AIFs and securitisation trusts.
For individual taxpayers, June should be used as a preparation month rather than a last-minute filing rush. Salaried employees should collect Form 16, investors should download capital gains statements, and taxpayers with bank interest, dividend income, property income or foreign assets should cross-check all entries with AIS and Form 26AS.
This is particularly important for taxpayers filing ITR-2 for AY 2026-27. Individuals with capital gains, more than one house property, foreign assets, foreign income, agricultural income above â‚ą5,000, lottery winnings, unlisted equity shares, NRI/RNOR status, company directorship or income above â‚ą50 lakh may need a more detailed return than ITR-1.

The practical message for June is simple: do not wait until the return filing deadline to review tax records. A few checks this month can help avoid wrong TDS claims, missed income reporting, incorrect capital gains entries and refund delays. With multiple due dates packed into June 2026, taxpayers and reporting entities should keep documents ready, reconcile data early and file only after verifying the numbers carefully.
