NRO fixed deposits, unlike tax-saver FDs, generally allow premature withdrawal — a genuinely common move when an NRI needs the rupee funds sooner than planned, or wants to react to a rate change. But breaking the deposit early sets off two separate adjustments that are easy to underestimate: the bank recalculates the interest you actually earn, and a penalty is deducted from it — and because TDS was already withheld from the higher, originally-contracted interest amount, that withholding now needs to be reconciled against a lower final figure.
How the interest recalculation and penalty work
On premature closure, banks generally don't pay out interest at the rate you locked in when you opened the deposit. Instead, interest is recalculated at whatever rate the bank was offering, at the time of booking, for the tenure the deposit actually ran — a shorter, often lower-rate bracket — and a penalty is then deducted on top, commonly cited in the 0.5%-1% range. The exact figure, and any amount-based exemptions from it, vary by bank, so confirm your bank's specific policy before assuming a number.
Minimum holding periods before any withdrawal is permitted at all also vary; some sources describe a very short minimum (on the order of days) for NRO deposits specifically — well short of the one-year minimum tenure, and outright forfeiture of interest for withdrawal before that year, that applies to NRE deposits. Because NRO and NRE premature-withdrawal rules genuinely differ and get conflated in casual conversation, don't assume your NRO FD follows an NRE-style forfeiture rule.
What happens to the TDS already deducted
This is the part that catches people out. NRO interest is subject to TDS at the time of credit or payment, whichever is earlier — commonly on a quarterly cycle for FDs held long enough to span multiple quarters — so by the time you close the deposit early, TDS has typically already been deducted, and deposited with the government, on interest calculated at the original, higher contracted rate for those already-completed quarters. Once the deposit closes early and total interest is recalculated downward, the TDS already paid over for earlier quarters can end up higher than the final, lower interest figure would justify.
How individual banks true this up in practice isn't something with a single consistent answer — some descriptions suggest the bank adjusts the final interest payout and TDS certificate to reflect the recalculated interest, but where TDS for earlier quarters has already been deposited under a return that's already been filed, a bank generally has no mechanism to claw it back from that filing. Treat this as a genuine open question to raise with your specific bank at closure, not something to assume works one way or the other.
Regardless of how the bank's internal accounting nets out, the backstop is the same one that applies to any excess NRO TDS generally: if TDS actually deducted across the deposit's life exceeds your real tax liability on the recalculated interest, the difference is recoverable by filing an Indian income tax return for that year and claiming a refund. Confirm the Form 16A the bank issues after closure reflects the recalculated interest — that's the figure your return should report, not the higher, originally-projected amount.
Before you break the FD
Worth confirming with the bank ahead of time: the exact penalty rate for your tenure/amount slab, whether a minimum holding period must be crossed before withdrawal is allowed at all, and how the bank will handle the TDS-versus-recalculated-interest gap on your certificate. None of this changes the basic math — recalculated interest, minus penalty, minus TDS on what's actually paid — but the mechanics vary enough between banks that a quick check before initiating closure can save a confusing reconciliation later.
