Treasury Bills Income Tax 2026 – Interest Income Guide for Investors

What Happened?

The Reserve Bank of India has announced a fresh auction of Government of India Treasury Bills on November 18, 2026 (Wednesday), with settlement on November 19, 2026 (Thursday). The auction includes three categories: 91-day bills (₹8,000 crore), 182-day bills (₹8,000 crore), and 364-day bills (₹7,000 crore), totaling ₹23,000 crore. Individual retail investors can now participate directly through the Retail Direct portal and competitive bidding on the Reserve Bank's E-Kuber system. This is significant for taxpayers as Treasury Bill interest income has distinct income tax treatment under the new Income Tax Act 2025.

Background & Legal Context

Treasury Bills are short-term debt instruments issued by the Government of India. They are issued at a discount and mature at face value—the difference constitutes interest income. From an income tax perspective, this interest income is fully taxable under the Income Tax Act, 2025.

Key Tax Provisions:

• Income Classification: Interest earned on Treasury Bills is classified as "Income from Other Sources" under Section 56 of the Income Tax Act, 2025. The discount (difference between face value and purchase price) is treated as interest income.
• Tax Deducted at Source (TDS): Under Section 194A of the Income Tax Act, 2025, banks and financial institutions must deduct TDS at 10% (basic rate) on interest income, including Treasury Bill interest. However, if you provide a valid PAN and your total income does not exceed the basic exemption limit, you may claim exemption from TDS by submitting Form 15G or 15H.
• Applicable for AY 2026-27: Interest received on Treasury Bills purchased in November 2026 (and maturing later) will be taxable in the Assessment Year 2026-27 and subsequent years, depending on maturity date.
• Corporate vs. Individual Taxpayers: Individual investors get the same TDS rate (10%), but corporate entities may have different TDS rates. All must report the gross interest in their income tax returns, claiming credit for TDS paid.

What Does This Mean for You?

For Individual Retail Investors:

If you participate in this Treasury Bill auction as a retail investor (maximum allocation: 5% of notified amount, which is ₹1,150 crore), here's what you must know:

• Interest Income is Fully Taxable: When your 91-day, 182-day, or 364-day Treasury Bill matures, the interest earned (discount) becomes taxable income. There is no exemption for government securities interest—this was clarified under the Income Tax Act 2025.
• TDS Will Be Deducted: The bank or depository participating in the auction will deduct TDS at 10% on the interest component. For example, if you earn ₹10,000 as interest, ₹1,000 will be deducted as TDS. You will receive ₹9,000, and ₹1,000 becomes a credit in your tax return.
• Claim Exemption if Eligible: If your total annual income is below ₹2,50,000 (basic exemption limit for AY 2026-27), you can submit Form 15G to avoid TDS deduction. Similarly, if you're a senior citizen with income below ₹3,00,000, Form 15H applies. You must submit this form before receiving the interest payment.
• Mandatory Reporting: Even if TDS is deducted, you must report the gross interest income in your Income Tax Return (ITR) for the relevant Assessment Year. Failure to report can trigger scrutiny under Section 142(1) of the Income Tax Act, 2025.
• No Tax-Free Status: Unlike certain government schemes (e.g., Senior Citizen Savings Scheme with partial exemption), Treasury Bill interest has no tax exemption. It is fully taxable at your applicable slab rate.

For Senior Citizens and Pensioners:

Treasury Bills are popular among retirees as a safe investment. However, the interest is taxable, and you cannot claim any special exemption. If your total income (including Treasury Bill interest) exceeds ₹3,00,000, you must file an ITR. The TDS mechanism ensures you pay tax gradually, but you remain liable for the full amount.

For Non-Resident Indians (NRIs):

NRI investors in Treasury Bills face different TDS treatment. Section 194A applies with a TDS rate of 10% for NRIs as well, but they have separate return filing obligations under Section 139 of the Income Tax Act, 2025.

What Should You Do Now?

Before Bidding:

• Understand Your Tax Bracket: Calculate your expected annual income for AY 2026-27. If you're below the basic exemption limit, prepare to file Form 15G/15H with your bank or depository to avoid TDS.
• Assess Your Investment Goal: Treasury Bills offer certainty but taxable returns. Compare the post-tax return with other investment options (e.g., tax-saving fixed deposits under Section 80C, or tax-free bonds).
• Check PAN Status: Ensure your PAN is active and linked with your bank account. The Reserve Bank requires valid PAN for bidding. Without PAN, you cannot participate, and TDS cannot be processed.

During and After Bidding:

• Bid Through Retail Direct Portal: Use the official Retail Direct portal for seamless bidding. Keep records of your bid confirmation, purchase price, and allotment details.
• Maintain Documentation: File and preserve all documents: auction notice, allotment letter, TDS certificates (Form 16A equivalent), and maturity proceeds receipt. These are required for ITR filing.
• Plan for Interest Receipt: When Treasury Bills mature, interest will be credited directly to your bank account. Ensure your bank has your latest TDS declaration (Form 15G/15H) on file if you claimed exemption.
• File Your ITR on Time: Report the gross interest income in your ITR for the relevant Assessment Year. Claim TDS as a credit against your tax liability. Late filing may attract penalties under Section 271F of the Income Tax Act, 2025.

For Compliance:

• Keep Transaction Records: Maintain bank statements, allotment confirmations, and maturity advices for 5-6 years for possible income tax scrutiny.
• Report to Multiple Sources: If you hold Treasury Bills across multiple banks, ensure each institution has your accurate TDS details to avoid over-deduction or mismatch.
• Monitor TDS Certificates: Obtain TDS certificates from each source and reconcile with your bank records. Mismatches must be corrected before ITR filing.

Key Takeaways

• Treasury Bill interest is fully taxable: There is no exemption under the Income Tax Act, 2025. All interest earned is classified as "Income from Other Sources" and subject to your applicable tax slab.
• TDS at 10% is mandatory: Unless you file Form 15G/15H (if income is below basic exemption limit), TDS of 10% will be deducted on interest. The TDS amount becomes a credit in your ITR.
• Mandatory ITR filing: Even if TDS is deducted, you must report gross interest in your ITR for the relevant Assessment Year to avoid penalties and scrutiny.
• PAN is essential: You must have an active PAN to bid in this auction. Without PAN, bidding and TDS processing are not possible.
• Post-tax returns matter: Calculate your post-tax return before investing. Compare with other options to ensure Treasury Bills align with your financial goals and tax position.
