Direct answer: report bank interest under the rules for your tax jurisdiction and tax year. There is no universal line, exemption or form. Canada generally treats bank interest as investment income and directs individuals to line 12100; India requires the interest to be disclosed in the eligible income-tax return and any tax deducted at source (TDS) claimed separately; Singapore exempts interest from deposits with approved Singapore banks but requires taxable interest from other sources under Other Income.
This guide covers those three official examples. Confirm your residence, the return year, the account or deposit type, ownership, and the authority’s current instructions before filing. A rule described for Canada, India or Singapore must not be carried across to another country.

Start with the five facts that determine the entry
Before opening a return, identify the facts that control whether the interest is taxable and where it belongs. The same bank statement can produce different answers for two taxpayers in different jurisdictions or years.

If you file in more than one country, each return needs its own analysis.
- Tax year: write down the year covered by the return and the period in which the bank paid, credited or accrued the interest. A calendar-year rule cannot be assumed for a financial-year return.
- Source and account type: separate an ordinary savings account, fixed or term deposit, certificate of deposit, GIC, foreign account and any interest reported by a broker or other institution. Exemptions can depend on the bank’s approval status or the product.
- Ownership: for a joint account, determine each person’s economic contribution rather than automatically assigning the entire statement amount to one owner.
- Tax already withheld: keep the gross interest and the tax deducted as separate figures. Withholding may create a credit, but it does not usually remove the obligation to disclose the income.
Gather the bank certificate or annual statement, transaction history showing payment or credit dates, ownership and contribution records for joint accounts, and any withholding certificate or tax-credit statement. Keep the documents for the retention period required by your authority.

How the three jurisdictions differ
| Jurisdiction | Tax treatment in the cited guidance | Return location or form issue | Timing and records point |
|---|---|---|---|
| Canada | Interest and other investment income form part of total income and must be reported. | Individuals report the result on line 12100. A T5 may not be issued when total investment income is under $50, but the interest remains reportable. | Report bank interest paid or credited in 2025 on the 2025 return. Compound GIC interest is reported for each complete investment year. |
| India | Interest is generally disclosed as income from other sources when the taxpayer is required to file; the correct return depends on eligibility. | For assessment year 2026-27 (financial year 2025-26), ITR-1 may cover certain resident individuals with total income up to ₹50 lakh, subject to all conditions. ITR-2 and ITR-3 apply in other circumstances. | Disclose the income even when a bank deducted TDS. Claim the TDS credit separately and reconcile AIS or pre-filled data with the bank’s certificate. |
| Singapore | Interest from deposits with approved Singapore banks is non-taxable. Interest from non-approved banks and other specified taxable sources must be declared. | Declare the full taxable amount under Other Income. Non-taxable approved-bank interest need not be declared. | Confirm the bank’s approval status and the source of the interest before deciding whether an entry is required. |
Canada: report interest on line 12100
What counts and what happens if there is no T5
Canada Revenue Agency guidance states that interest and other investment income form part of total income and must be reported on the return. For bank accounts, report interest paid or credited in 2025 on the 2025 return, even if the bank did not send a T5 slip. The CRA notes that a T5 may not be issued when total investment income is under $50. That $50 figure concerns slip issuance; it is not a tax-free threshold.
Use the bank’s annual statement and account history to determine the amount. If the statement and a T5 differ, do not silently choose the more convenient number. Check whether one document covers a different period, includes a correction, or reports a different account, then retain the explanation with your records.
Enter the amount on the applicable line
The CRA directs individual filers to line 12100, Interest and other investment income. Do not substitute a guessed generic “interest” line from an older return or another country’s form. The line number is tied to the Canadian return and year being filed.

Compound GIC and term-deposit interest
Interest can be earned and reinvested before it is paid to you. For a compound GIC or term deposit, the CRA says to report interest earned during each complete investment year even when no annual payment or slip is received. The relevant event is the completed investment period, not simply the day cash reaches your chequing account.

For example, an investment that began on July 1, 2024 has a first complete investment year ending June 30, 2025. Interest for that period belongs on the 2025 return. Interest earned from July 2025 through June 30, 2026 belongs on the 2026 return. Use the institution’s accrual or maturity statement to divide the amount by the correct periods.
Joint accounts: allocate by contribution
For a joint bank account, the CRA generally expects each person to report a share based on that person’s contribution to the funds. A 50/50 split is appropriate only when the underlying contributions support it. If one holder supplied all or most of the money, preserve deposit records and allocate the interest consistently with those contributions.
Do not use the names printed on the account as the sole test of ownership. Save the opening deposit records, transfers and any written agreement that explains the beneficial ownership. Apply the same approach in later years unless the contributions change.
Foreign interest and currency conversion
Report foreign interest in Canadian dollars. CRA guidance generally points to the Bank of Canada exchange rate in effect when the amount arises. Keep the foreign-currency statement, the rate used and the conversion calculation so another person can reproduce the Canadian-dollar figure.
Do not subtract foreign tax from the interest reported as income. A foreign tax credit may be available in the relevant circumstances, but that is a separate calculation from reporting the gross foreign interest. The availability and amount of any credit depend on the taxpayer’s complete Canadian return and the foreign tax documentation.
Canada filing checklist
- Collect every 2025 bank statement, T5 and GIC or term-deposit certificate.
- List interest paid or credited, including amounts for which no T5 was issued.
- Split compound deposits by each complete investment year.
- Allocate joint-account interest according to contributions.
- Convert foreign interest to Canadian dollars using the applicable Bank of Canada rate when the amount arose.
- Enter the resulting amounts on line 12100 and retain the supporting calculations.
India: choose the eligible return, disclose interest and claim TDS separately
Use the assessment-year and financial-year labels correctly
For assessment year 2026-27, covering financial year 2025-26, the Income Tax Department describes several individual return forms. Interest may be included as income from other sources, but the form depends on the taxpayer’s full circumstances rather than the interest amount alone.
| Form described by the Income Tax Department | Interest-reporting relevance | Eligibility points stated for AY 2026-27 |
|---|---|---|
| ITR-1 (Sahaj) | May include income from other sources such as interest. | For certain resident individuals with total income up to ₹50 lakh, subject to the form’s other conditions. |
| ITR-2 | Used when the individual or HUF has no income taxable under business or profession but does not fit ITR-1. | Form selection requires checking the complete income and circumstances. |
| ITR-3 | Used where business or professional income exists; interest must still be disclosed in the appropriate section. | Do not select ITR-1 solely because the interest is small if another eligibility condition directs you to ITR-3. |
The ITR-1 description also states separate limits of ₹1.25 lakh for the specified Section 112A long-term capital-gains condition and ₹5,000 for the agricultural-income condition. Those figures are form-eligibility conditions, not an exemption or reporting threshold for bank interest.
Report the gross income even when TDS was deducted
The Income Tax Department’s ITR-1 FAQ says that a taxpayer must disclose income on which a bank deducted tax at source and claim the TDS credit in the return. Treat these as two entries in your working papers: the interest income and the tax already withheld. Entering only the net amount would understate the income.
Reconcile the TDS figure with the bank’s certificate and the tax-credit information available through the department’s systems. If the credit does not match, contact the bank or follow the department’s correction process rather than changing the interest amount to force a match.
Use AIS and the interest certificate as a cross-check
The Statement of Financial Transactions (SFT) filing guide explains that banks and other specified reporting entities submit interest information for pre-filling. It also says that an interest certificate is provided to help account holders reconcile information displayed in the Annual Information Statement (AIS). This is a matching aid, not a guarantee that pre-filled data is complete or correct.
Compare each AIS entry with the bank statement, the account number or deposit reference, the period and the gross interest. Investigate duplicated entries, missing accounts and amounts assigned to the wrong financial year. Make the return reflect the supported figure and retain the reconciliation.
The SFT guide states that reporting entities must not subtract the ₹10,000 Section 80TTA deduction in their SFT interest reporting. Therefore, do not reduce the bank’s reported interest by ₹10,000 merely because that number appears in the SFT guidance. Any deduction must be considered separately under the rules and eligibility applicable to your return.

India filing checklist
- Confirm that you are filing for financial year 2025-26 and assessment year 2026-27, or identify the correct pair for another year.
- Collect bank interest certificates, statements and TDS certificates for every account or deposit.
- Review AIS and other pre-filled information against those records.
- Determine whether ITR-1, ITR-2 or ITR-3 fits your complete income and eligibility; do not decide from interest alone.
- Disclose the interest in the appropriate income section.
- Enter the TDS credit separately and resolve mismatches before submission.
Singapore: determine whether the bank and deposit are approved
Approved-bank deposits
Inland Revenue Authority of Singapore guidance says interest from deposits with approved banks in Singapore is non-taxable. That interest need not be declared in the income tax return. The exemption depends on the deposit being with an approved Singapore bank, so keep evidence of the institution and account type.

Interest from deposits with non-approved banks and other specified sources is taxable. IRAS instructs taxpayers to declare the full taxable amount under Other Income. Do not enter only the amount left after a bank charge or withholding unless the applicable instructions specifically require a different computation.
“You must declare the full amount of your taxable interest under ‘Other Income’ in your Income Tax Return.”

Singapore decision steps
- Identify the account or deposit that generated the interest.
- Confirm whether the bank is an approved bank in Singapore for the relevant period.
- Separate approved-bank interest from interest from non-approved banks or other taxable sources.
- Leave qualifying non-taxable approved-bank interest out of the return.
- Declare the full taxable amount under Other Income and keep the statement supporting the calculation.

- Inventory the accounts: include savings, current, term, fixed, GIC, foreign and jointly held accounts, plus any deposit reported by another institution.
- Classify taxability: check whether the source is exempt, taxable or subject to a special rule. Singapore’s approved-bank exemption illustrates why the bank’s status matters.
- Determine the timing rule: use the authority’s required basis—paid, credited or accrued for the relevant period. Canada’s complete-investment-year rule for compound GICs is an example of accrual timing.
- Calculate the reportable amount: start from the supported gross figure, allocate joint ownership correctly and convert foreign currency as required.
- Find the official destination: use the current line, schedule, category or return form. Canada’s line 12100 and Singapore’s Other Income are jurisdiction-specific destinations.
- Separate withholding: record tax deducted as a credit or equivalent only where the authority permits it. India’s TDS process demonstrates why withholding and income disclosure are separate.
- Reconcile: compare slips, certificates, pre-filled data and statements. Correct omissions or duplicates before filing.
- Save the audit trail: retain statements, calculations, exchange-rate evidence, ownership records and correspondence about corrections.
Common mistakes and how to correct them
Assuming no slip means no reporting
A missing information slip can reflect a reporting threshold or an administrative omission. Canada’s guidance explicitly says interest remains reportable when a T5 is not issued for amounts under $50. Use the bank statement and the authority’s instructions instead of treating the missing slip as an exemption.

Reporting only the net amount after withholding
Withholding is tax paid in advance, not automatically a reduction of income. India’s FAQ requires disclosure of the interest and a separate TDS credit. Keep the gross and withheld figures distinct in every worksheet.
Using the wrong year for a deposit
Payment dates do not always determine the reporting year. Compound deposits may require allocation by completed investment year, as in the Canadian GIC example. Check the certificate’s accrual schedule before copying the maturity amount into one return.
Splitting a joint account 50/50 without evidence
Legal title and economic contribution can differ. For Canadian joint accounts, the CRA generally bases each person’s share on contributions. Gather deposit records and apply a supportable allocation rather than an automatic equal split.

For Canadian reporting, foreign interest is reported in Canadian dollars without subtracting foreign taxes. A possible foreign tax credit is considered separately. Do not assume another jurisdiction follows the Canadian treatment.
Accepting pre-filled data without reconciliation
India’s AIS and SFT data can help identify income, but the taxpayer remains responsible for a correct return. Compare every entry with bank records and investigate differences before filing.
Carrying an exemption across borders
Singapore’s approved-bank exemption does not establish a Canadian or Indian exemption. Start again with the rules of the return being filed and the source of the interest.
Records to keep
- Annual bank statements and interest certificates for each account or deposit.
- Information slips such as a Canadian T5 or Indian TDS certificate, when issued.
- Payment, credit or accrual dates, including maturity schedules for compound deposits.
- Deposit and transfer evidence showing contributions to joint accounts.
- Foreign-currency statements and the exchange-rate calculation used.
- Proof of withholding, tax-credit statements and correspondence correcting mismatches.
- For India, a copy or export of AIS data used in the reconciliation.
- For Singapore, evidence of the bank’s approval status and the classification of each interest source.
These records let you explain why the amount on the return differs from a statement total, a pre-filled figure or a later maturity payment.
When to obtain jurisdiction-specific help
Use the authority’s current taxpayer guidance or a qualified adviser when residence spans countries, a deposit is jointly owned with a non-contributor, a foreign tax credit may apply, a business or professional activity affects India form eligibility, or a Singapore account’s approval status is unclear. The official examples here establish the reporting framework, but they do not determine your filing obligation, tax rate, deduction entitlement or refund.
