Income Tax Refund: What It Is, Who Gets It, How It’s Calculated, and What Happens If It’s Delayed or Denied
By the FinanceChecks.com Editorial Team | Published October 1, 2026 | Last reviewed October 1, 2026 | 9-minute read
Every tax season, lakhs of Indians file their returns and then settle into the same quiet waiting game, refreshing the income tax portal every few days to see if the refund has landed. Most people understand the basic idea, you overpaid, now you get money back, but far fewer understand why the amount comes out the way it does, what the department legally owes you if it takes too long, or what to actually do when a refund status turns into “failed” or “adjusted” instead of “credited.”
This guide walks through all of it: what a tax refund actually is, who qualifies, exactly how it’s calculated, and the real steps to take when it’s delayed or denied.
Quick Answer
A tax refund is the excess tax you’ve already paid, through TDS, advance tax, or self-assessment tax, being returned to you after your actual tax liability for the year is calculated and found to be lower. Anyone who has paid more tax than they owe, whether salaried, self-employed, or a business, is entitled to claim it by filing an income tax return. The refund amount is simply the difference between tax already paid and tax actually due, computed automatically when your return is processed under Section 143(1). If the refund is delayed beyond the statutory timeline, you’re entitled to simple interest under Section 244A, generally 0.5% per month, calculated from April 1 of the assessment year if you filed on time. A refund can be denied or reduced if the department adjusts it against an outstanding tax demand from an earlier year under Section 245, or it can simply fail to reach you due to incorrect or unvalidated bank details, both of which have specific fixes.
About This Guide
This guide was compiled by the FinanceChecks.com editorial team using the Income Tax Act, 1961, specifically Sections 237, 244A and 245, along with guidance from the Income Tax Department’s e-filing portal and published analysis from tax advisory sources on refund processing and delay resolution. Refund processing timelines and bank validation requirements are procedural and can shift from year to year, so we recommend checking your specific return’s status directly on the e-filing portal for the most current information on your case.
What Is a Tax Refund, Exactly?
A tax refund isn’t a bonus or a gift from the government, it’s simply your own money coming back to you. Through the year, tax gets deducted from your income in advance, via TDS on your salary, interest, or other payments, or through advance tax instalments you pay yourself if you’re self-employed or have significant non-salary income. At the end of the financial year, when you file your income tax return, your actual tax liability is calculated based on your real total income, deductions and exemptions. If the tax already collected from you turns out to be more than what you actually owed, the excess is refunded.
This is why refunds are common among salaried employees in particular. Employers often deduct TDS based on conservative estimates or without accounting for every deduction you’re eligible for, such as investments under Section 80C, health insurance premiums, or home loan interest, so the actual liability calculated at filing time frequently comes in lower than what was already deducted.
Who Is Eligible for a Tax Refund?
Anyone who has paid more tax than their actual liability for a financial year can claim a refund, regardless of whether they’re a salaried individual, a freelancer, a business owner, a Hindu Undivided Family, or a company. The eligibility isn’t about income level or category, it’s purely about the gap between tax paid and tax owed. Common situations that create this gap include excess TDS deducted by an employer or bank, advance tax paid based on an estimate that turned out higher than actual income, tax paid on income that later qualified for an exemption or deduction not accounted for earlier, and tax deducted at source on fixed deposit interest or other income even though your total taxable income falls below the taxable threshold.
The refund itself is only processed if you file an income tax return for that year and specifically claim it, it is not issued automatically without a filed and verified return.
How Is the Refund Amount Actually Calculated?
The calculation itself is straightforward in principle, even though the underlying numbers can get detailed.
Step 1: Total tax paid. This includes TDS deducted on your behalf (reflected in Form 26AS and your Annual Information Statement), any TCS collected, and advance tax or self-assessment tax you’ve paid directly.
Step 2: Actual tax liability. This is calculated on your total taxable income for the year, after applying all eligible deductions and exemptions, using the tax slab rates applicable under whichever tax regime you’ve chosen.
Step 3: The difference. If tax paid exceeds tax liability, the excess is your refund. If tax liability exceeds tax paid, you owe additional tax instead.
The Income Tax Department’s Centralized Processing Centre (CPC) runs this calculation automatically once your return is filed and e-verified, and issues what’s called an intimation under Section 143(1), a summary showing exactly how your refund (or demand) was arrived at, including any adjustments the department made to the figures you originally reported.
What Happens If Your Refund Is Delayed?
This is where many taxpayers don’t realise they have a legal entitlement, not just a reasonable expectation. Under Section 244A of the Income Tax Act, the department is required to pay you simple interest if your refund is delayed, and this isn’t discretionary, it’s a statutory right.
The standard rate is 0.5% per month, or part of a month, which works out to 6% annually. If you filed your return by the due date, this interest is calculated from April 1 of the relevant assessment year until the date the refund is actually granted. If you filed late, interest generally runs from the date of filing instead. A few conditions apply: interest is only payable if the refund amount exceeds 10% of your total tax liability as determined, and if a delay is specifically attributable to you, say, you were slow to respond to a department query, that period gets excluded from the interest calculation.
There’s a notable boost available too. If your refund arises from an appellate order, such as a decision in your favour from the CIT(Appeals) or an Income Tax Appellate Tribunal, and the department doesn’t pay it within three months of the order, you’re entitled to an additional 3% per annum on top of the standard rate.
One detail that catches people off guard at filing time the following year: this interest is itself taxable, reportable as “Income from Other Sources” in the year you actually receive it.
| Scenario | Interest Rate | Period Covered |
|---|---|---|
| Return filed on time, refund from TDS/advance tax | 0.5% per month (6% p.a.) | From April 1 of the assessment year to the date of refund |
| Return filed late | 0.5% per month (6% p.a.) | From the date of filing to the date of refund |
| Refund less than 10% of total tax determined | No interest payable | Not applicable |
| Refund arising from an appellate order, paid late | Additional 3% per annum on top of the standard rate | From one month after the order until payment |
| Delay caused by the taxpayer (e.g., slow response to a query) | That period excluded from interest calculation | Only the department-caused delay counts |

What Happens If Your Refund Is Denied or Reduced?
A refund doesn’t always arrive in full, or at all, and there are two genuinely different reasons this happens, each with its own fix.
It can be adjusted against an old outstanding demand. Under Section 245 of the Income Tax Act, if you have a pending tax demand from an earlier assessment year, the department can set off your current refund against it, either partially or in full. Before doing this, the department is required to send you an intimation proposing the adjustment, and you generally have 30 days to respond, either agreeing with the demand, disputing it with supporting reasons, or paying the amount separately to protect your current refund. If you don’t respond within the window, the adjustment can proceed anyway, so this notice is not one to ignore.
It can simply fail to reach you. This is a logistics problem rather than a legal one. Common causes include an incorrect bank account number or IFSC code entered in the return, a bank account that hasn’t been pre-validated on the e-filing portal, a mismatch between the name on your PAN and the name on your bank account, or a dormant or closed bank account. When this happens, your refund status typically shows as “Refund Failure” rather than “Refund Issued,” and the fix is to correct and pre-validate your bank details on the portal, then submit a specific “Refund Reissue Request.”
| What You See on the Portal | What It Means | What To Do |
|---|---|---|
| Refund Issued | Refund has been sent to your bank account | Check your bank statement; allow a few days for crediting |
| Refund Failure | Refund could not be credited (bank account issue) | Correct and pre-validate your bank account, then submit a Refund Reissue Request |
| Refund Adjusted | Current refund set off against an old outstanding demand | Review the Section 245 notice; respond within 30 days if you wish to dispute it |
| Demand Determined | The department has calculated a higher tax liability than you reported | Review your intimation under Section 143(1); file a rectification if you believe it’s incorrect |
| Under Processing | Return is still being processed by CPC | Wait; check again after a reasonable interval, typically a few weeks |
What to Actually Do, Step by Step
If it’s simply taking a while, first check your return’s processing status on the e-filing portal rather than assuming the worst. Refunds are typically credited within a few weeks of the Section 143(1) intimation being issued, and a short wait within that window is completely normal, not a sign of a problem.
If the status shows “Refund Failure,” log into the e-filing portal, go to the bank account section, correct any errors in the account number or IFSC code, and ensure the account is pre-validated and has ECS enabled. Once that’s done, submit a Refund Reissue Request through the portal’s service request section.
If the status shows “Refund Adjusted” and you’ve received a Section 245 notice, read it carefully to understand which earlier year’s demand is being set off. If you believe that old demand was incorrect or has already been resolved, respond to the notice with your reasons and any supporting documents rather than letting the adjustment go through by default. If the demand is genuinely valid, you can choose to accept the adjustment or pay it separately if you’d rather preserve the current year’s refund in full.
If your refund seems unreasonably delayed well beyond the usual processing window, and no clear status explains why, you can raise a grievance through the e-filing portal’s grievance redressal mechanism, which creates a formal, trackable request for the department to look into your case specifically.
Common Mistakes Taxpayers Make
A frequent mistake is not pre-validating the bank account before filing, which is one of the single most common and entirely avoidable causes of a refund failure. Another is ignoring a Section 245 notice simply because it looks like routine department correspondence, when failing to respond within the 30-day window can mean the adjustment proceeds even if you had a valid dispute. People also often assume any delay automatically means something is wrong, when processing within the normal window is routine, and checking the portal status is far more useful than guessing. Finally, many taxpayers forget to report Section 244A interest as income in the following year’s return, since it’s easy to overlook a relatively small interest credit buried in the refund amount, but it is taxable and expected to be reported.
My Take
What’s worth understanding here is that a tax refund delay isn’t something you simply have to accept and wait out indefinitely. The law builds in real compensation for delays attributable to the department, and real, fixable processes for the two most common reasons a refund doesn’t show up, a bank account issue or an old demand adjustment. Neither of these requires a tax professional to resolve in most cases, they require checking the actual status on the portal rather than guessing, and acting within the response windows the law gives you.
The habit worth building, long before refund season arrives, is simple: keep your bank account pre-validated on the e-filing portal year-round, and don’t let an old tax demand sit unresolved, since it has a way of resurfacing exactly when you’re expecting money back rather than owing it.
