NRO Account Interest TDS & Tax Guide 2026: DTAA, Refund & Filing

A Singapore-based client called me frustrated: “Bank ne mera poora FD interest khaali kar diya — ₹1.2 lakh aaya aur ₹36,000 TDS kat gaya.” I asked where he lived. Singapore. I said: “Under the India-Singapore DTAA you were entitled to 15% TDS — not 30%. And if your total India income is below ₹2.5 lakh — the entire ₹36,000 is refundable.” He was stunned. “Nobody told me.”

That is the NRO interest problem in one conversation. Banks deduct 30% TDS automatically — without checking DTAA entitlement, without checking whether the NRI’s total India income even crosses the basic exemption limit. The solution requires two documents submitted to the bank once a year, an annual ITR filing, and knowing one key fact: 30% TDS is not the final tax. This guide covers the complete picture.

💡 The Most Important Fact: 30% TDS deducted by the bank on NRO interest is NOT final tax. DTAA reduces it to 10–15% with two documents. If your total India income is below ₹2.5 lakh — actual tax is zero and the full TDS is refundable. Neither benefit arrives automatically — both require proactive action.

NRO vs NRE — The Tax Difference That Costs NRIs Lakhs

Account	Interest Taxability	TDS	On ₹20L FD at 7%
NRE Account	Completely tax-free	Zero TDS	₹1,40,000 interest — zero tax
NRO Account	Fully taxable	30% by bank (Section 195)	₹1,40,000 interest — ₹42,000 TDS deducted
FCNR Account	Completely tax-free	Zero TDS	Interest (in foreign currency) — zero tax

⚠️ Foreign Earnings in NRO = Avoidable Tax: Foreign salary or income deposited into NRO generates 30% TDS on interest. The same deposit in NRE generates zero TDS — interest is completely tax-free. If you are keeping foreign earnings in an NRO account instead of NRE or FCNR — you are paying tax that does not need to be paid. India income (rent, pension, dividend) must go to NRO — no choice. Foreign income has a choice — always choose NRE or FCNR.

NRO Interest TDS — Exactly What the Bank Deducts

Under Section 195 of the Income Tax Act (NRI payments) — banks deduct TDS on NRO interest at the applicable rate. The rate depends on whether DTAA documents have been submitted:

Situation	TDS Rate	Effective Rate (with 4% cess)
No DTAA documents — default	30%	~31.2%
Income ₹50L–₹1 crore — surcharge applies	30% + 10% surcharge	~34.32%
DTAA — USA, UK, Canada, Singapore, Australia	15%	~15.6%
DTAA — Germany, Netherlands, Japan	10%	~10.4%
UAE NRIs — limited DTAA benefit	30% (generally)	~31.2%

UAE NRIs — Special Situation: The UAE has no personal income tax. India-UAE DTAA provides limited interest rate benefit because the treaty mechanism works by reducing double taxation — but if UAE does not tax the income, there is limited treaty-based reduction of Indian TDS. UAE NRIs generally cannot reduce NRO TDS to 10–15% via DTAA the way USA/UK/Singapore NRIs can. However, if total India income is below ₹2.5L — ITR filing provides a full refund of the 30% TDS regardless of DTAA.

Actual Tax vs TDS — The Refund Opportunity

Bank deducts 30% TDS on NRO interest. But the actual income tax applicable depends on your total India income and applicable slab rates — which may be significantly lower. The difference is a refund, available only through ITR filing:

Total India Income	Actual Tax Rate	Tax on ₹1.5L NRO Interest	TDS Deducted	Refund
₹1.5L (only NRO interest)	0% (below ₹2.5L exemption)	₹0	₹45,000	₹45,000
₹3L (rent ₹1.5L + interest ₹1.5L)	5% on ₹50,000 above ₹2.5L	₹2,500	₹45,000	₹42,500
₹6L (various India income)	5% + 20%	Variable	₹45,000	Partial
₹15L+ (high India income)	30%	₹45,000	₹45,000	None

✅ Key Insight: An NRI with ONLY NRO FD interest of ₹1.5 lakh and no other India income — actual income tax liability is ZERO (below ₹2.5L basic exemption). But bank deducts ₹45,000 TDS. The entire ₹45,000 is refundable — but ONLY if an ITR is filed. Without filing, the refund is never processed. File every year where TDS has been deducted.

Two Real Examples With Complete Calculations

Example 1 — Singapore NRI: DTAA Reduces TDS by ₹21,000/Year

Priya, Singapore. NRO FD: ₹20 lakh at 7% = ₹1,40,000 annual interest.

Scenario	TDS Rate	TDS Amount	Net Interest Received
Without DTAA (default)	30%	₹42,000	₹98,000
With India-Singapore DTAA (15%)	15%	₹21,000	₹1,19,000
Annual saving (TRC + Form 10F submitted)		₹21,000 less TDS	₹21,000 more in hand

Over 5 years: ₹1,05,000 additional interest retained — from two documents submitted to bank once a year. Priya also files ITR to verify actual tax against the 15% TDS rate.

Example 2 — USA NRI: DTAA + ITR Refund Combined

Mr. Sharma, USA. NRO FD interest: ₹4,50,000. No other India income this year.

Step	Amount
NRO interest	₹4,50,000
Bank TDS (30% — no DTAA submitted)	₹1,35,000 deducted
India-USA DTAA applicable rate	15% = ₹67,500
Actual India slab rate tax on ₹4.5L	₹10,000 (5% on ₹2L above ₹2.5L exemption)
TDS deducted by bank	₹1,35,000
ITR refund (₹1,35,000 − ₹10,000)	₹1,25,000 refundable

Mr. Sharma did not submit TRC + Form 10F in time. Bank deducted ₹1,35,000. His actual tax: ₹10,000. ITR refund: ₹1,25,000. Without ITR filing — ₹1,25,000 stays with government permanently. Next year: submit TRC + Form 10F to bank in April → TDS drops to 15% (₹67,500) → ITR refund of ₹57,500 (₹67,500 − ₹10,000).

USA Return — Foreign Tax Credit: Mr. Sharma also reports this ₹4.5L interest in his US federal return (worldwide income). Tax in USA at 22% federal on $5,400 (approx) = approximately $1,188. Less: India tax credit (₹10,000 ≈ $120). Net USA tax: ~$1,068. No double taxation — the DTAA mechanism works as designed. He gets credit in USA for what he paid India. He uses IRS Form 1116 (Foreign Tax Credit) for this.

How to Get DTAA Benefit — Step by Step

1Get TRC in February/March
Apply to your country’s tax authority: IRS Form 6166 (USA, 4–6 weeks), HMRC Certificate (UK, 2–3 weeks), IRAS Certificate (Singapore, 1–2 weeks), CRA Letter (Canada, 2–4 weeks), ATO Certificate (Australia, 2–3 weeks). TRC must specify the relevant Indian financial year period. Renew every year — TRC is year-specific.
2File Form 10F Online
Login to incometax.gov.in → e-File → Income Tax Forms → Form 10F. Fill: country of residence, Tax ID number in that country, Indian PAN, period of NRI residence, address abroad. Upload TRC as attachment. Submit. Save the acknowledgment number. This is a mandatory additional declaration — TRC alone is insufficient.
3Submit Both Documents to EVERY Bank
Submit TRC + Form 10F acknowledgment to each bank where you have an NRO account — separately. This is a critical point: DTAA benefit does not automatically apply to all banks when submitted to one. Each bank must receive the documents independently. Typically submitted to the NRO account branch or via email to NRI banking desk. Request written confirmation of DTAA rate update.
4Verify Form 16A Each Quarter
Banks issue Form 16A (TDS certificate) quarterly. Verify that TDS is being deducted at the DTAA rate (15%), not at 30%. If Form 16A shows 30% TDS despite submitting documents — follow up with bank immediately. Correction is easier mid-year than at ITR filing time.
5File ITR — Declare Interest, Claim Refund
File ITR-2 by August 31 (Budget 2026 deadline). In Schedule OS — declare NRO interest as income from other sources. In Schedule TR — claim DTAA benefit (country, article number — typically Article 11 for interest). In Schedule TDS — TDS credit from Form 16A. Compute actual tax liability — excess TDS becomes refund. Pre-validate NRO account on portal for refund credit.

NRO FD vs NRO Savings vs NRO RD — TDS Differences

Account Type	Typical Interest Rate	TDS Rate	Strategy
NRO Savings Account	3–4% per annum	30% (Section 195)	Small amounts — file ITR to claim full refund if income below ₹2.5L
NRO Fixed Deposit	6.5–7.5% per annum	30% (reducible to 10–15% via DTAA)	Large deposits — submit TRC + Form 10F to bank in April every year
NRO Recurring Deposit	Similar to FD rate	30% (same reduction available)	Same DTAA process as FD

💡 Multiple NRO Accounts — Submit to Each Bank Separately: If you have NRO accounts at SBI, HDFC, and Axis Bank — TRC + Form 10F must be submitted to all three banks separately. Submitting at one bank does not automatically apply DTAA at the others. Each bank maintains its own TDS records. This is the most common reason NRIs find DTAA applied at one bank but 30% still deducted at another.

Section 80TTB — Does It Apply to NRIs?

⚠️ Section 80TTB Does NOT Apply to NRIs: Section 80TTB allows resident senior citizens (60+) to deduct up to ₹50,000 of bank interest income from taxable income. This deduction is NOT available to NRIs — regardless of age. Some NRI senior citizens expect this benefit and are surprised when it does not apply. The only benefits available to NRI interest income: the basic exemption limit (₹2.5L — no higher limit for NRI senior citizens unlike resident seniors), and DTAA rate reduction.

NRO Interest in Your Residence Country’s Tax Return

For NRIs in countries with worldwide income reporting (USA, UK, Canada, Australia) — NRO interest must be declared in the foreign country’s tax return as well. This is where DTAA’s double taxation protection operates:

USA: Report NRO interest as foreign interest income in federal return. Claim India TDS as Foreign Tax Credit using IRS Form 1116. Net: US tax on income minus credit for India tax already paid.
UK: Report in Self Assessment return. Claim Foreign Tax Credit for India TDS in the foreign income section.
Canada: Report in T1 return. Claim Foreign Tax Credit on Schedule T2209.
Australia: Report in ATO return. Claim Foreign Income Tax Offset for India TDS.
Non-disclosure consequences: Serious penalties in residence country for unreported foreign income. AEoI (Automatic Exchange of Information) agreements mean both countries now share financial account data — non-disclosure is increasingly detected automatically.

NRO to NRE Transfer and Foreign Repatriation

NRO to NRE Transfer

India-source income that has been received in NRO (after tax) can be transferred to NRE. Once in NRE — further interest is tax-free and the amount is freely repatriable.

Annual limit: $1 million per financial year
Require: Form 15CB (CA certificate that applicable taxes are paid) + Form 15CA (online self-declaration at incometax.gov.in)
CA involvement recommended for this step

NRO to Foreign Account (Repatriation)

Same $1 million annual limit applies
Form 15CA + Form 15CB required (same process)
Bank processes the foreign wire transfer after documents are submitted
For amounts above $1 million — RBI special permission required

⚠️ FEMA Violation Risk for Transfers Without 15CA/15CB: Repatriating money from NRO abroad without Form 15CA and 15CB (for amounts requiring these forms) is a FEMA violation — regardless of whether the money was legitimately earned in India and tax was properly paid. Always complete the Form 15CA/15CB process through a CA before any large NRO-to-foreign transfer.

Seven Common Mistakes NRIs Make with NRO Interest

Mistake 1 — Not submitting TRC + Form 10F to bank: The most common and most expensive. 30% TDS deducted when 15% was applicable. On ₹20L NRO deposit at 7% — ₹21,000 excess TDS annually. Over 5 years: ₹1.05 lakh. Submit both documents every April. Renew TRC annually.

Mistake 2 — Submitting documents to only one bank: Multiple NRO accounts across banks — DTAA submitted at the home bank, ignored at others. Each bank independently deducts TDS. Submit TRC + Form 10F at every NRO account bank, separately, every April.

Mistake 3 — Not filing ITR — treating TDS as final tax: Bank deducted 30% — treated as done. Actual India tax: 5% or zero (depending on total income). Refund of ₹40,000–₹1,25,000 goes unclaimed. File ITR every year where TDS has been deducted — regardless of whether you think income is “small.”

Mistake 4 — Keeping foreign salary in NRO: Foreign earnings deposited to NRO generate 30% TDS on interest. Same amount in NRE — zero TDS. The mandatory use of NRO is for India-source income only. Foreign earnings have a choice — always NRE or FCNR.

Mistake 5 — Not reporting NRO interest in residence country return: USA, UK, Canada, Australia — worldwide income reporting is mandatory. NRO interest must be declared. With DTAA Foreign Tax Credit — double taxation is avoided. Non-declaration is a serious offense in the residence country, now detectable through AEoI data sharing.

Mistake 6 — Transferring NRO funds abroad without Form 15CA/15CB: For qualifying transfers — Form 15CB (CA certificate) and Form 15CA (online declaration) are mandatory before the bank can process the foreign remittance. Transfers without these for amounts that require them are FEMA violations. Always go through a CA for repatriation above the exempted limits.

Mistake 7 — Not checking AIS before ITR filing: Bank reports all NRO interest payments to the Income Tax Department — which appears in the NRI’s AIS. If NRO interest in AIS is not declared in ITR — the system flags the mismatch and a notice follows. Always download AIS before filing, declare all income shown there, and raise feedback for any incorrect entries.

Frequently Asked Questions

Q1. I am in UAE — can I reduce NRO TDS via DTAA?
Generally limited for UAE NRIs. The UAE has no personal income tax. India-UAE DTAA has specific provisions, but the interest rate benefit available to US/UK/Singapore NRIs is not similarly available to UAE NRIs in most standard cases. However, if your total India income is below ₹2.5 lakh — file an ITR and claim a full refund of the 30% TDS. That route is available to all NRIs regardless of country of residence, as it is based on India’s domestic tax law, not DTAA.

Q2. Bank deducted 30% TDS without my consent — I had no TRC. What can I do?
You can still claim the DTAA benefit retrospectively at ITR filing time. Obtain your TRC now (even if after the financial year) and file Form 10F. In your ITR — declare the NRO interest in Schedule OS, claim DTAA rate in Schedule TR, and the difference between 30% TDS and the applicable DTAA rate (15%) becomes a refund. File before August 31 (Budget 2026 deadline). CA guidance recommended for Schedule TR.

Q3. Am I entitled to Section 80TTB deduction on NRO interest as a senior citizen NRI?
No. Section 80TTB (₹50,000 deduction on bank interest for senior citizens) applies exclusively to resident senior citizens — not to NRIs. NRI senior citizens get no special higher exemption limit (the basic limit is ₹2.5L for all NRIs) and no Section 80TTB deduction. The available benefits are: basic exemption limit, DTAA rate reduction, and ITR refund for income below the exemption limit.

Q4. NRO FD interest ₹96,000 per year from parents’ property rent deposited. Taxable?
Yes — India-sourced rental income credited to NRO is taxable in India. ₹96,000 is below the ₹2.5L basic exemption limit — so actual income tax is zero. However, bank may deduct TDS on the interest portion (not rent — if rent is credited directly and TDS is deducted at source by tenant). File ITR — declare the rent income (with 30% standard deduction allowed on rental income) and NRO interest — claim refund of any TDS deducted. Net tax likely zero.

Q5. Can NRO to NRE transfer be done without CA involvement?
Form 15CB (the CA certificate) is required for most qualifying transfers. Without a CA to sign Form 15CB — the bank will not process the NRO-to-NRE transfer (or foreign repatriation) for amounts that require it. Some small transfers below FEMA exemption limits may not need 15CB — but ₹10L+ transfers will generally require it. Engage a CA for this process — the Form 15CB is a statutory document only a CA can issue.

Conclusion

NRO account interest taxation has three layers of opportunity that most NRIs miss: first, DTAA reduces the TDS rate from 30% to 10–15% with two documents submitted to the bank every April; second, slab rate tax on total India income is often significantly lower than 30% — generating large ITR refunds; third, foreign earnings should never be in NRO when NRE or FCNR provides tax-free interest on the same deposit.

The Singapore NRI’s frustration at the start of this guide — “Bank ne mera poora interest khaali kar diya” — resolves with three actions: TRC + Form 10F to every NRO bank in April, ITR filed by August 31, and any foreign savings moved to NRE going forward. These three actions, done once a year, convert unnecessary tax loss into retained interest income every year for the duration of the NRI career.
