Taxation of Interest on Bonds and Debentures in India

Updated 11 October 2026 · Fact-checked

Interest on bonds, debentures, government securities and bank deposits is taxed as income from other sources at your slab rate. It is taxed on an accrual or receipt basis, depending on your method of accounting. Payers may deduct TDS under section 193 or 194A. TDS is only an advance payment, not the final tax.

Understand Taxation of Interest on Bonds and Debentures

Every rupee of interest you earn from a bond, debenture, government security or bank deposit is income. Under the Income-tax Act, 1961, interest on securities is normally taxed under the head Income from Other Sources. The exception is when the holding is a business activity, which is rare for retail clients.

The tax rate is your slab rate. There is no special low rate for resident individuals. A client in the 30% slab pays 30% on the interest, plus surcharge if applicable and 4% health and education cess. This is why interest from debt often feels heavy for high-income clients, and why tax-free bonds are attractive to them.

Timing matters. Interest can be taxed when it accrues (mercantile method) or when it is received (cash method), depending on the method the taxpayer regularly follows. For a cumulative deposit or bond that pays everything at maturity, the exam often expects you to spread the interest year by year as it accrues. Interest is not left untaxed until maturity.

Tax can also be cut at source. TDS on interest on securities falls under section 193. TDS on interest other than interest on securities, such as bank deposits, falls under section 194A. The usual resident rate is 10%, with thresholds and exemptions that change over time. Many listed securities held in demat form are paid without TDS. TDS is credited against your final tax, so you still report the full interest in your return.

As an adviser, you compare the post-tax yield of products. Always convert a pre-tax rate into a post-tax rate using the client's slab before you recommend anything.

Key formulas to remember

Head of income: Interest on bonds, debentures, G-secs, deposits → Income from Other Sources (section 56); Unless the holding is part of a business, in which case it is business income.
Tax on interest: Tax = Interest × slab rate × (1 + 4% cess); Add surcharge first if the client's income crosses the surcharge limits. Use only the slab rate when the question ignores cess.
Post-tax yield: Post-tax yield = Pre-tax yield × (1 − tax rate); Use the effective rate including cess for a precise comparison.
TDS on interest on securities: Section 193: TDS at 10% for residents, subject to exemptions and thresholds; Many listed securities held in demat form and most government securities are paid without TDS. Check the workbook for current limits.
TDS on other interest: Section 194A: interest other than interest on securities, e.g. bank deposits, TDS at 10% above the prescribed threshold; The threshold differs for senior citizens and has been revised from time to time. Verify the current figure.
Accrual of cumulative interest: Interest for year n = Opening balance of year n × rate (annual compounding); Each year's interest is taxable in that year on accrual basis, even if paid at maturity.
TDS is not final tax: Tax payable = Total tax on income − TDS credit; The full interest is always reported in the return.

How to solve Taxation of Interest on Bonds and Debentures questions

Use this order for any question on tax on interest from debt instruments.

1Identify the instrument: corporate bond or debenture, government security, bank deposit or tax-free bond. Tax-free bond interest is exempt.
2Identify the taxpayer: resident or non-resident, and individual or company. Note the slab rate given.
3Decide the head. Treat the interest as income from other sources unless the question says it is business income.
4Decide the year of taxation. Use the accrual method for cumulative interest and the method stated in the question.
5Compute the gross interest for that year. Use the period actually held and the correct principal.
6Apply the slab rate and cess as the question directs. Do not add surcharge unless it is given.
7Check TDS. Identify the section (193 or 194A) and whether the threshold or exemption applies. Treat TDS as a credit, not the final tax.
8Compute the post-tax yield if the question asks for it, then check which option matches your figures.

Quickest way: Rate, head, timing, TDS in four checks

When to use it: Use it when you have under a minute per MCQ and the options differ in tax amount or in who bears TDS.

Say the head first: other sources, taxed at slab rate.
Multiply interest by the slab rate. Add 4% of that tax if cess is mentioned.
If the interest is cumulative, take only the portion accrued in the year asked.
Eliminate any option that treats TDS as the final tax, or that exempts ordinary taxable interest.

Common mistakes in Taxation of Interest on Bonds and Debentures

Treating interest on bonds as capital gains.
Students link bonds with capital gains because of selling at a profit.
Fix: Separate the two. Periodic coupon or interest is other sources. Gain or loss on sale before maturity is capital gains.
Taxing cumulative interest only at maturity.
Cash is received only at maturity, so it feels like the income arises then.
Fix: Allocate interest to each year as it accrues, using the compounding method given.
Assuming TDS ends the client's tax liability.
The payer has already deducted tax, so it looks settled.
Fix: TDS is only a credit. Compare it with the tax at the client's slab and pay or claim the difference.
Mixing section 193 and section 194A.
Both deal with TDS on interest and both use similar rates.
Fix: Remember: 193 is interest on securities (bonds, debentures, G-secs). 194A is other interest, such as bank deposits.
Ignoring cess in a post-tax comparison.
Students stop at the slab rate.
Fix: If the question mentions cess, multiply the tax by 1.04. Check whether surcharge is given.
Taxing tax-free bond interest.
All bond interest is assumed taxable.
Fix: Interest on notified tax-free bonds is exempt. Check the instrument name before you compute anything.

Worked examples

Example 1

A resident individual in the 30% slab earns ₹80,000 as interest on listed corporate debentures in a year. Ignoring surcharge, what is the tax on this interest including 4% cess?

Show the solution

Head: income from other sources, taxed at slab rate.
Tax at 30% = ₹80,000 × 30% = ₹24,000.
Cess at 4% = ₹24,000 × 4% = ₹960.
Total tax = ₹24,000 + ₹960 = ₹24,960.

Answer: ₹24,960

Example 2

Rohit invests ₹5,00,000 in a cumulative deposit giving 8% a year, compounded annually, for 3 years. He follows the accrual method. How much interest is taxable in the second year? Options: (a) ₹40,000 (b) ₹43,200 (c) ₹46,656 (d) ₹1,29,856

Show the solution

Year 1 interest = ₹5,00,000 × 8% = ₹40,000. Balance becomes ₹5,40,000.
Year 2 interest = ₹5,40,000 × 8% = ₹43,200. Balance becomes ₹5,83,200.
Year 3 interest = ₹5,83,200 × 8% = ₹46,656.
Total interest is ₹1,29,856, but only year 2's accrual is taxed in year 2.
Option (b) matches. Option (a) is year 1, option (c) is year 3, and option (d) is the total.

Answer: (b) ₹43,200

Exam tips

Check whether the question says the interest is accrued or received. It decides the year of tax.
Match each TDS section with its instrument: 193 for securities, 194A for deposits and other interest.
Read whether cess and surcharge are included. Compute only what the question asks.
Watch for tax-free bonds in the options. Their interest is exempt, so any taxable answer is wrong.
Use the percentage of marks lost on a wrong answer. On a 2-mark caselet question, skip it if you are unsure.

Taxation of Interest on Bonds and Debentures: frequently asked questions

Under which head is interest on bonds and debentures taxed?

It is normally taxed under income from other sources. If the holding is part of a business, it is business income. Gains from selling the bond are capital gains, not interest.

What is the difference between TDS under section 193 and 194A?

Section 193 applies to interest on securities, such as debentures and government bonds. Section 194A applies to other interest, such as bank deposits. Both are advance tax and the thresholds and exemptions can change, so check the current workbook.

Is interest on bonds taxed when it is received or when it accrues?

It depends on the taxpayer's regular method of accounting, cash or mercantile. For cumulative deposits or bonds, exam questions usually expect year-by-year accrual taxation. Interest is not deferred until maturity.

Is the tax finished once TDS is deducted?

No. TDS is only a credit against your final tax. You must report the full interest in your return and pay any shortfall, or claim a refund if TDS exceeds your tax.
