Your Bank Loves You. Your Tax Bill Proves It.
TL;DR
Indian banks welcome NRI deposits but rarely explain the tax traps. Here are 7 mistakes that quietly cost NRIs thousands every year.

Mistake 1: Not converting your savings account to NRO/NRE
The moment you leave India for employment and become an NRI, you're required to convert your resident savings account to NRO. Most people don't. The bank doesn't chase you because they don't want to lose the deposit.
Why it matters: If the bank later discovers you're an NRI operating a resident account, they'll reclassify it, deduct TDS retroactively at 30% on all interest earned, and you'll have a compliance headache.
Fix: Convert proactively. Open NRE for foreign earnings (tax-free interest), NRO for Indian income. It takes one branch visit or an online request.
Retroactive 30% TDS on every rupee of past interest
Bank discovers you're an NRI on a resident account to reclassification + 30% TDS recalculated on all interest earned during your NRI years. Years of small FD interest can add up to a five-figure surprise.
Mistake 2: Keeping all your FDs in NRO instead of NRE
NRO FD interest is taxed at 30% TDS (or DTAA rate if you've claimed it). NRE FD interest is completely tax-free in India. Zero TDS.
If you have foreign earnings that you're parking in Indian FDs, put them in NRE, not NRO. The interest rate is the same. The tax treatment is night and day.
NRO is for money earned IN India, rent, dividends, maturity proceeds. You can't avoid NRO for those. But fresh deposits from your salary abroad? NRE, always.

Mistake 3: Not claiming DTAA on NRO interest
Even for the money that's stuck in NRO, you don't have to accept 30% TDS. Your DTAA treaty likely caps it at 10-15%. But the bank won't apply this automatically.
You need to submit your TRC and Form 10F to the bank's NRI cell. Not the branch manager, the NRI compliance desk. If they still deduct at 30%, file your ITR claiming the treaty rate and get the excess back as a refund.
This is the single most common mistake Gulf NRIs make. The average UAE NRI loses ₹18,000/year on NRO FD interest alone because nobody told them about DTAA.

Default 30% TDS vs the 12.5% UAE treaty rate is a 17.5% gap on every rupee of NRO interest. Per the prose above, recoverable for the current year via ITR and up to 5 past Assessment Years via Section 119(2)(b) condonation.
Mistakes 4-7: The rest of the list
Mistake 4. Not tracking TDS across multiple banks: If you have FDs in SBI, HDFC, and ICICI, each deducts TDS separately. Your 26AS shows all of it, but many NRIs only check one bank's statement. Download 26AS and see the full picture.
Mistake 5. Ignoring NRO savings account interest: Yes, even the 3-4% on your NRO savings account faces 30% TDS. Small amounts, but they add up over years. DTAA applies to this too.
Mistake 6. Not updating KYC after changing countries: If you moved from UAE to Singapore, your DTAA rates might change. Update your bank's KYC with your new address and residency proof. Old TRC from UAE won't work for Singapore rates.
Mistake 7. Not filing ITR because “no taxable income”: Even if your total Indian income is below the taxable threshold, TDS has already been deducted. The only way to get it back is filing an ITR. No filing = money gone forever.
Four quieter mistakes, each costing real money
Less obvious than the first three, but the same pattern: small amounts compounding into real money over the years.
Only checking one bank's statement
FDs in SBI + HDFC + ICICI each deduct TDS separately. 26AS is the only place you see all of them at once. Most NRIs check one bank and miss the rest.
Ignoring NRO savings interest
Even the 3-4% on your NRO savings balance faces 30% TDS. Tiny per month, real over years. DTAA caps this too, most NRIs never claim it.
Stale KYC after a country move
Moved UAE to Singapore? Your old UAE TRC won't unlock the India-Singapore treaty rates. Update KYC + TRC at the new country before the next interest credit.
Skipping the ITR because income looks small
Below the threshold doesn't mean below the refund. TDS was already deducted at source. No ITR = money stays with the government forever.

The exceptions that change the answer
Where the general rule stops applying to you
Every rule below has a carve-out, a cut-off date or a condition that flips the answer. These are the ones that decide real cases.
TDS on NRO account interest
Right now: 30% plus surcharge and cess
Where it works differently
- A valid TRC and Form 10F (Form 41 from 1 Apr 2026) are furnished
- The treaty rate applies, commonly 10-15% under Article 11.
- s.90(2) gives the more beneficial of treaty or Act.
- No PAN is furnished
- s.206AA imposes at least 20%, but Rule 37BC allows escape by furnishing name, address, TIN and TRC. Courts have also held s.206AA cannot override a treaty rate.
- Rule 37BC + settled case law.
- Claiming the treaty rate at source
- The s.115A(5) filing exemption is lost, so an Indian return becomes necessary.
- That exemption requires TDS at not less than the s.115A rate.
- The account is NRE or FCNR instead
- Interest is exempt and no TDS applies, while the holder is a FEMA non-resident.
- s.10(4)(ii) and s.10(15)(iv)(fa).
Commonly got wrong
- NRO interest TDS is 30%. Incomplete. Surcharge and 4% cess sit on top, so the effective rate is higher.30% plus surcharge and cess, around 31.2% at the base level.
- You can file Form 15G/15H to stop NRO TDS. Those are resident-only declarations. An NRI filing one makes a false declaration.Use Form 13 (Form 128 from 1 April 2026), or claim the treaty rate with a TRC.
