An interest certificate request letter is a short, formal letter asking your bank to issue a statement of interest earned on your deposits, or interest paid on your loan, for a stated period. The single most useful detail to include is the exact period you need, usually a full financial year such as 1 April 2026 to 31 March 2027, along with every account number the certificate should cover. With those in place, most banks can issue the certificate without back-and-forth.
Key takeaways
- Interest certificates come in two kinds: interest earned on deposits and interest paid on loans.
- You typically need them for your income-tax return, for claiming eligible loan-interest deductions, and for audits.
- Name the period, the account numbers and whether you need TDS details in the certificate.
- Banks often provide certificates through net banking too; the letter is for when you need a signed copy or a consolidated one.
- Check the certificate against your statements and your tax records when it arrives.
Deposit or loan: know which certificate you need
| Certificate type | What it shows | Typical use |
|---|---|---|
| Deposit interest certificate | Interest credited or accrued on savings, fixed and recurring deposits, and any tax deducted at source | Reporting interest income in your return; reconciling with tax records |
| Loan interest certificate | Interest and principal paid on a home, education, vehicle or business loan during the period | Claiming eligible deductions; business accounts |
| Provisional loan certificate | Expected interest and principal for the current year | Declaring investments to an employer during the year |
| Business account interest summary | Interest on overdraft, cash credit or term loans | Books of account and audit |
If you hold both deposits and loans with the same bank, ask for separate certificates. They serve different purposes and are easier to file separately.
When you are likely to need one
Most people ask for an interest certificate around tax time. Interest earned on deposits is income, and banks deduct TDS on it in many cases. A certificate showing interest and TDS for the year helps you report the income correctly and check that the tax deducted appears against your PAN.
Loan interest certificates matter if you are eligible for a deduction on home loan or education loan interest. Which deductions apply, and up to what limits, depends on current income-tax law and your circumstances, so ask your CA rather than relying on a certificate alone.
Businesses need interest summaries for their books and for audit. An auditor may also ask for a balance confirmation as at year-end, which is a separate letter but often requested at the same time.

Worked examples
Kiran Joshi, a freelance consultant in Nagpur, has a savings account and two fixed deposits with her bank. In April 2027 she downloads interest statements from net banking but finds they cover the accounts separately and do not show TDS clearly. She sends a one-page letter asking for a consolidated certificate for FY 2026–27 with interest and TDS for each account, and receives a signed PDF by email. Her CA uses it to reconcile her interest income with the tax deducted against her PAN.
Brightwater Analytics Pvt Ltd, a services exporter in Chennai, has a cash credit facility and a fixed deposit holding part of its export earnings. Its auditor asks for the year's interest figures. The finance manager writes on the company letterhead, signed by the director whose name is on the bank mandate, asking for an interest certificate for both accounts and a balance confirmation as at 31 March 2027. Both letters go together, and the bank responds with the two documents.
Checking the certificate when it arrives
Do not just file it. Spend five minutes checking:
- The period matches what you asked for.
- All the accounts you listed are included.
- Interest figures agree with your passbook or statements.
- TDS shown matches what your tax records show against your PAN.
- For loans, the property address and co-borrower names are correct.
If something is off, write back promptly with the specific discrepancy. Banks set their own processes and timelines for corrections, so ask your branch what it needs. For more letter formats, see our guide on how to write a formal letter to a bank manager.

Frequently asked questions
What is an interest certificate from a bank?
It is a statement issued by the bank showing the interest earned on your deposits, or the interest paid on your loan, over a specified period. Deposit certificates usually also show any tax deducted at source on that interest.
Can I download an interest certificate instead of writing a letter?
Many banks make interest certificates available through net banking or their app. A letter is useful when you need a signed copy, a consolidated certificate across several accounts, or details that the downloadable version does not show.
What period should I mention in the request?
Usually the financial year, for example 1 April 2026 to 31 March 2027, because that is what tax returns and audits use. For a provisional loan certificate, mention the current financial year and that you need projected figures.
Who can request an interest certificate for a company account?
An authorised signatory of the company, writing on the company letterhead. The signatory should be someone already registered with the bank for that account, so the request is accepted without extra verification.
Does an interest certificate show TDS?
Deposit interest certificates usually show TDS if any was deducted. If yours does not, ask the bank to include it, and cross-check the figure with the tax records available against your PAN.
Bottom line
A clear request that names the period and every account usually gets you the right certificate first time. Generate a ready letter with our free interest certificate request tool and check the certificate as soon as it arrives.
