Many taxpayers are relieved when their income tax refund finally reaches their bank account, especially after long delays. In several cases, refunds are credited along with an additional interest amount. This often raises an important question: Is income tax refund interest taxable? The answer is clear and often misunderstood—yes, it is taxable.
Understanding how income tax refund interest is taxed can help taxpayers avoid errors while filing their next income tax return and prevent unnecessary notices later.

Why Interest Is Paid on Income Tax Refunds
Interest on income tax refunds is paid when excess tax paid by a taxpayer is returned after processing delays. This interest compensates for the time the government retained the excess amount. However, interest is not automatic in every situation and depends on filing timelines and processing conditions.
The interest is calculated at a fixed rate and credited along with the refund amount. Although it feels like compensation, it is still treated as income under tax law.
Is Income Tax Refund Interest Taxable?
Yes, income tax refund interest is taxable. The interest received on an income tax refund must be declared as taxable income. It is not tax-free and does not enjoy any exemption, regardless of the amount received.
This interest income is taxable under the head “income from other sources.” It is added to the taxpayer’s total income and taxed according to the applicable income tax slab rate.
If the refund interest relates to a previous financial year but is received in the current year, it must be taxed in the year of receipt, not the year to which the refund relates.
Which Financial Year Should Refund Interest Be Reported In?
Income tax refund interest is taxed in the financial year in which it is received. For example, if refund interest related to FY 2024-25 is credited during FY 2025-26, it must be reported while filing the return for FY 2025-26.
Many taxpayers mistakenly ignore this income, assuming tax has already been adjusted. However, refund interest is credited without tax deduction at source, making self-declaration mandatory.
How Is Interest on Income Tax Refund Calculated?
Interest on income tax refunds is calculated at 0.5% per month, which equals 6% annually. The interest period usually starts from the date of filing the return or payment of tax, whichever is later, and ends on the date the refund is issued.
However, interest is not paid for delays caused by the taxpayer, such as late filing or incorrect information. Additionally, if the refund amount is small compared to total tax payable, interest may not be applicable.
Tax Treatment Under Income From Other Sources
Under income tax provisions, any income not falling under salary, business, capital gains, or house property is classified as income from other sources. Interest on income tax refunds falls squarely under this category.
No deductions are allowed against this income. The full interest amount must be added to total income and taxed at slab rates applicable to the taxpayer.
Common Mistakes Taxpayers Should Avoid
Many taxpayers forget to report income tax refund interest while filing returns. Others assume it is exempt or already adjusted. These mistakes can lead to mismatches in income reporting and future tax notices.
Always check the refund details carefully and include the interest component while calculating total income.
Income tax refund interest may feel like a bonus, but it is fully taxable. Proper reporting ensures compliance and avoids future penalties. Understanding how refund interest is taxed allows taxpayers to plan better and file accurate returns every year.
