Government Securities Conversion 2026: Tax Treatment & Investor Guide

What Happened?

The Government of India, through the Reserve Bank of India (RBI), has announced a large-scale conversion/switch auction of government securities aggregating ₹25,000 crore (face value) on November 16, 2026. This auction allows market participants to exchange their existing government securities (source securities) maturing between 2027-2029 for longer-dated destination securities maturing between 2034-2062. The switch is designed to help investors manage their portfolio maturity profiles while the government manages its debt structure.

The auction operates on a multiple-price basis through the RBI's e-Kuber platform, with bids accepted between 10:30 AM and 11:30 AM on November 16, 2026. Settlement will occur on November 17, 2026 (T+1 basis). Six source securities with varying maturity dates are being switched into six destination securities with longer tenures.

Background & Legal Context

Income Tax Treatment Under Income Tax Act 2025

Government securities transactions are governed by specific provisions of the Income Tax Act 2025. Key sections affecting this switch/conversion are:

• Section 47 (Income Tax Act 2025): Certain transactions in securities are exempted from capital gains tax. Government securities transactions, when held as investments, generally fall under this exemption category, meaning conversion typically does not trigger taxable capital gains for individual investors.
• Section 194LA (Interest on Government Securities): Interest income earned on government securities is taxed as income from other sources. During the switch, accrued interest calculations become critical for tax purposes.
• Section 56 (Income from Other Sources): Any gains arising from the switch that do not qualify for exemption under Section 47 would be taxable under this section as income from other sources.

Accrued Interest Treatment

The operational guidelines explicitly address net accrued interest settlement. When you switch securities, the accrued interest on source securities (from last coupon date to settlement date) is credited to you, while accrued interest on destination securities (from settlement date to next coupon date) is debited. This net settlement is crucial for tax accounting:

• Accrued interest received is treated as income from securities held as investment
• This interest income is subject to income tax at your applicable slab rate (AY 2026-27 onwards)
• If you are below the taxable income threshold, you may not owe tax, but reporting is mandatory

Fund Settlement and Cash Consideration

The guidelines provide for cash settlement due to rounding-off of destination security face value. When the destination security face value is rounded down to the nearest ₹10,000 multiple, the odd amount is bought back at the quoted price. The illustration shows how ₹6,290 of odd amount securities becomes ₹6,240 cash consideration. This cash component, though small, is technically a sale transaction and should be reported in your ITR if applicable.

What Does This Mean for You?

For Individual Investors

If you hold any of the six source securities (7.38% GS 2027, 8.26% GS 2027, 7.37% GS 2028, 7.26% GS 2029, 7.10% GS 2029, or 7.04% GS 2029) and participate in this switch auction, the following tax implications apply:

• No Capital Gains Tax: The conversion of one government security into another typically does not trigger capital gains tax because Section 47 of the Income Tax Act 2025 exempts such transactions.
• Accrued Interest is Taxable Income: However, the net accrued interest you receive as part of the settlement is taxable income in the year of receipt. For AY 2026-27, any net accrued interest received during FY 2026-27 must be included in your total income.
• Interest Income Deduction Eligibility: If you are a senior citizen (age 60+), you may be eligible for deduction under Section 80TTB (now under the new Income Tax Act 2025 structure), which provides relief on interest income from certain securities.
• ITR Filing Requirement: Even if your total income is below the taxable threshold, you must report government securities transactions if you want to carry forward losses or maintain clarity in your records.

For Institutional Investors (Mutual Funds, Insurance Companies, Banks)

Institutional participants face more complex considerations:

• Portfolio Rebalancing: Switch transactions allow portfolio rebalancing without triggering capital gains, important for fund performance tracking.
• Marked-to-Market (MTM) Accounting: For category I Alternative Investment Funds and certain institutional investors, MTM gains/losses on securities held may already be taxed. The switch does not change this treatment.
• Cash Consideration Treatment: The cash received for odd amounts should be segregated and documented separately as it represents a partial sale.

Documentation and Reporting

Under the Income Tax Act 2025, you must maintain proper records of:

• Bid amount and prices quoted in the switch auction
• Allocation details received from RBI
• Net accrued interest component settled
• Cash consideration for odd amounts, if any
• Settlement date and securities received (ISIN numbers)

These records become essential if the Income Tax Department questions your calculations during assessment or scrutiny in AY 2026-27 or later years.

What Should You Do Now?

Step 1: Verify Your Holdings

Check your demat account and government securities holdings to confirm if you hold any of the six source securities eligible for this switch. Minimum bid size is ₹10,000.

Step 2: Understand Your Tax Status

Determine your income tax slab for FY 2026-27 (AY 2026-27). If you are:

• Below taxable income threshold: Accrued interest may still be taxable on receipt
• Senior citizen: Check Section 80TTB benefits
• Institutional investor: Confirm your fund's valuation methodology (MTM vs. non-MTM)

Step 3: Plan Your Switch Strategy

Decide which source-destination security pair suits your portfolio needs. The switch does not trigger tax, but the interest component will. Ensure the destination security's maturity aligns with your investment horizon.

Step 4: Execute on e-Kuber

On November 16, 2026, between 10:30 AM and 11:30 AM, submit your bid through the e-Kuber Switch Transaction module with:

• Face value of source security you want to sell
• Price equal to FBIL closing price of previous working day
• Choice of destination security and your bid price

Step 5: Document for Tax Records

Once allocation is confirmed on November 16, 2026, and settlement occurs on November 17, 2026, immediately download and save:

• Auction bid confirmation from e-Kuber
• Allotment advice
• Settlement statement showing accrued interest and cash consideration

Step 6: Report in ITR

When filing your ITR for AY 2026-27 (by July 31, 2027), report the accrued interest income under "Income from Other Sources" (Schedule OS if applicable under the new Income Tax Act 2025 structure). Attach supporting documentation.

Key Takeaways

• No Capital Gains Tax: Conversion of government securities under Section 47, Income Tax Act 2025 is exempt from capital gains tax for individual investors holding securities as investments.
• Accrued Interest is Taxable: Net accrued interest received during switch settlement is taxable income in the year of receipt and must be reported in ITR for AY 2026-27.
• Cash Consideration Reporting: Small cash amounts received for rounding-off of destination security face value are technically taxable and should be documented separately.
• Institutional Investors Exempt from Capital Gains on Section 47 Transactions: Mutual funds, insurance companies, and banks also benefit from the exemption, though MTM provisions may apply separately.
• Documentation is Critical: Maintain complete records of bid details, allocation advice, and settlement statements for 6 years as per Income Tax Act 2025 record retention requirements. Non-compliance can lead to scrutiny assessments under Section 142(1) during AY 2026-27 or later.
