When you invest in bonds, you can earn income from two main sources. The first is interest income, which you receive periodically from the bond issuer. The second is capital gains, which may arise if you sell the bond in the secondary market before its maturity.

Under the Income Tax Act, 1961, both these types of income are taxable and create different filing requirements. To remain compliant with tax rules and avoid penalties or notices, it is important to understand these obligations. 

This article explains five major tax filing requirements related to bond investments that you should be aware of for FY 2025–26 (AY 2026–27).

Want to Remain Tax Compliant? 5 Tax Filing Requirements You Must Complete for FY 25-26

As an investor, the first step toward tax compliance is assessing which tax regime works better for you. Under the Income Tax Act, 1961, taxpayers can choose between the old tax regime and the new tax regime. 

To make the right selection, you may:

• Calculate your total tax liability under both regimes 
• Select the one that results in lower tax outgo

Once the suitable regime is selected, you may complete the following five tax filing requirements for FY 2025–26:

1. Reporting Interest Earned from Bonds

Under the Income Tax Act, 1961, income must be reported under five different heads:

• Income from Salary
• Income from House Property
• Profits and Gains from Business or Profession (PGBP)
• Capital Gains
• Income from Other Sources

Now, the coupon interest you receive from bonds must be reported under the head “Income from Other Sources.” For tax purposes, this interest income is treated similarly to interest earned from bank fixed deposits. 100% of the interest amount is:

• Added to your total taxable income 
• Taxed according to your applicable income tax slab rate

Additionally, the income must be reported when it becomes due or on an “accrual basis”. For example:

• Suppose you purchased a bond that pays ₹10,000 as annual interest every March. 
• Assume that the interest for FY 2025–26 becomes due on March 31, 2026.
• Now, it must be reported as income for FY 2025–26 even if the payment is credited to your account in April 2026. 

2. Reporting Capital Gains if Bonds are Sold Before Maturity

If you sell a bond in the secondary market before its maturity date, the difference between the selling price and your purchase price is treated as capital gain or capital loss. This amount must be reported separately under the head “Capital Gains.”

The tax treatment depends on:

• Was the bond listed or unlisted?
• How long did you hold it before selling?

Firstly, let’s check out the latest bond taxation rules related to “listed bonds” (after considering the amendments introduced in the Union Budget 2025):

Holding Period	Type of Capital Gain	Tax Treatment
Less than 12 months	Short-Term Capital Gain (STCG)	Taxed at the investor’s applicable income tax slab rate
12 months or more	Long-Term Capital Gain (LTCG)	Taxed at 12.5% without indexation

Whereas, if we talk about the tax treatment for “unlisted bonds”, as per Section 50AA, any unlisted bond that is transferred, matured, or redeemed on or after July 23, 2024, will always be treated as STCG (regardless of how long the bond was held). Thus, the profit will be taxed at the taxpayer’s applicable income tax slab rate.

3. Proper TDS Reporting + Raising Claims

Under Section 193, the issuer may deduct TDS at 10% on the interest income before paying it to the investor. When filing your ITR, you must verify that this deducted tax is correctly reflected in Form 26AS and the Annual Information Statement (AIS) available on the Income Tax Department portal. 

Let’s check out some actions you may take:

Filing Requirements	What You Should Do
Check Tax Records	Verify that the TDS deducted on your interest income from bonds appears in both Form 26AS and AIS. Note that any mismatch between the TDS records and your reported income may increase the risk of scrutiny or tax notices.
Match the Income	If you are filing your return online on the Income Tax Department portal, the system usually “prefills” certain income details automatically. Review these prefilled figures and make sure they correctly reflect the actual interest income earned from bonds (on an accrual basis) during the financial year.
Claim the Credit	Claim the deducted TDS while filing your ITR. Failure to do so may lead to an unnecessarily higher income tax liability.

4. Choose the Correct ITR Form

While filing your income tax return, you must select the correct ITR form (available from ITR-1 to ITR-7) and submit it before the prescribed due date. It is highly important because filing under the wrong form may lead to:

• Processing delays
• Defective return notices
• The need to revise the return later.

So, which ITR form may be used by the bond investors? You may consider the following: 

When You Can Use ITR-1	When You Should Use ITR-2
You can file ITR-1 (Sahaj) if you only have interest income and there are no capital gains from selling bonds, subject to other conditions.	If you sold bonds before maturity and earned capital gains, you cannot use ITR-1.  In such cases, you must file ITR-2, subject to conditions. This ITR form allows taxpayers to report both STCG and LTCG.

However, realize that both ITR 1 and ITR 2 cannot be used if you have income from a business or profession that is taxable under “Profits and Gains of Business or Profession (PGBP).” In such cases, ITR-3 or ITR-4 may apply, subject to conditions:

Situation	ITR Form
Business or professional income under “normal taxation.”	ITR-3
Business income under the “presumptive taxation” scheme (subject to eligibility limits).	ITR-4

5. Disclosure of Foreign Bond Investments in ITR

If any Resident and Ordinary Resident (ROR) investor holds foreign bond investments (such as US Treasury bonds or foreign corporate bonds), these holdings must be disclosed in:

• Schedule FA (Foreign Assets) 
• Schedule FSI (Foreign Source Income). 

Let’s check out the various filing requirements in this segment:

Schedule in ITR	What It Is Used For	What You Must Report
Schedule FA	It is a section in ITR-2 and ITR-3 where ROR taxpayers disclose foreign assets.	Details of foreign assets such as bank accounts, stocks, bonds, and immovable property held outside India during the calendar year (Jan 1 to Dec 31).
Schedule FSI	It is used to report income earned outside India	Income such as foreign interest, dividends, or capital gains from overseas investments.

Additionally, if taxes have already been paid in another country on the same income, such taxpayers may claim relief under the Double Taxation Avoidance Agreement (DTAA). This relief is claimed in Schedule TR (Tax Relief) in the ITR.

In Summary, Bond Investors Must Correctly Report Income, Verify TDS, and Select the Right ITR Form in 2026

Now you are aware of the several tax filing requirements that apply when you invest in bonds. By meeting these obligations, you remain compliant and reduce the risk of attracting notices or scrutiny from the Income Tax Department. 

If we revise, the five tax filing requirements you must satisfy for FY 2025–26 (AY 2026–27) are:

• Report bond coupon interest under “Income from Other Sources.”
• Disclose capital gains from selling bonds before maturity.
• Verify TDS records and claim the correct credit in ITR.
• Choose the correct ITR form based on your income sources.
• Disclose foreign bond holdings in Schedule FA and FSI, if applicable.
