When you owe advance tax as an NRI, and the interest that follows

You assumed TDS covered everything, and now there is a tax shortfall with interest piling on it that you did not see coming.

As an NRI you are used to TDS being deducted on your Indian income, and it is easy to assume that settles the tax. Sometimes it does not: a buyer under-deducted on a property or share sale, or your rental income had less tax withheld than you actually owe. The gap is advance tax, payable in instalments through the year, and if it is not paid the department adds interest, sometimes a surprising amount, on top of the tax. There is a helpful rule for one-off gains, and a trap that the rule does not cover.

The short answer

If your Indian tax after TDS is ₹10,000 or more in the year, you owe advance tax, payable in instalments (15% by 15 June, 45% by 15 September, 75% by 15 December, 100% by 15 March), and shortfalls carry interest at 1% a month. For a one-off capital gain that arises late in the year, a special rule spares you the instalment-shortfall interest (Section 234C) provided you pay the tax on that gain in the instalment after it arose, or by 31 March. But that relief is only from 234C; if your total advance tax still falls short of 90% of what you owe, the separate Section 234B interest from 1 April of the assessment year still runs. This is the common trap when a buyer under-deducts TDS on a sale.

When advance tax applies, and the instalments

Advance tax is due when your Indian tax liability, after the TDS already deducted, comes to ₹10,000 or more in the financial year (Section 208). It is paid in four instalments through the year: 15% by 15 June, 45% by 15 September, 75% by 15 December and the whole by 15 March, each figure being the cumulative amount that should have been paid by that date.

For most NRIs, TDS handles the tax on routine income, so advance tax does not arise. It bites when TDS falls short: a buyer who under-deducted on a sale, rental income with too little withheld, or a gain no one deducted on at all. When the withheld tax does not reach your real liability, the balance is advance tax, and paying it on the instalment dates is what avoids the interest below.

The relief for a late one-off gain

There is a fair rule for income you could not have predicted. Under the proviso to Section 234C, where you fell short on the earlier instalments because of a capital gain, or certain other one-off income like a large dividend, that arose only later in the year, you are not charged the 234C instalment-shortfall interest on those earlier instalments, provided you pay the full tax on that gain in the instalment falling due after it arose, or, if no instalment is left, by 31 March.

So an NRI who sells a property in February and pays the tax on the gain by 15 March, or 31 March, is not penalised under 234C for not having paid it in the June or September instalments, because the gain had not yet happened then. This is genuine relief, and it means a late-year sale does not automatically carry instalment interest.

The trap: 234C relief does not cover 234B

Here is the part that catches people. The 234C relief above deals only with the instalment-shortfall interest. It does not touch Section 234B, which is a separate charge: if the total advance tax you paid during the year is less than 90% of your finally assessed tax, interest at 1% a month runs from 1 April of the assessment year until you pay, regardless of the 234C relief.

So on that February property sale, if the buyer under-deducted and you did not pay the balance as advance tax by year end, you can still face 234B interest even though 234C was waived. The two are independent, and this is exactly the common NRI trap: assuming TDS covered a sale, discovering it did not, and finding interest has been accruing. A practising CA computes the real liability, times the advance-tax payment to use the 234C relief, and minimises the 234B exposure.

What's involved

What the CA actually does

  1. 1

    We work out the real shortfall

    We compute your actual Indian tax against the TDS already deducted, so you know whether advance tax is due and how much.

  2. 2

    We time the payment for the 234C relief

    Where a capital gain arose late in the year, we pay the tax on it in the right instalment or by 31 March, so the 234C instalment interest is waived.

  3. 3

    We minimise the 234B exposure

    Because 234B is separate and runs from 1 April, we get the balance paid promptly to stop that interest growing, and factor it into the return.

  4. 4

    We reconcile it in the return

    We carry the advance tax and TDS into your return so the final liability, and any interest, is correctly computed and no surprise demand follows.

What to have ready

Documents you'll typically need

  • Details of the income where TDS fell short (sale, rent)
  • The TDS actually deducted, from Form 26AS
  • The dates the income arose, for the 234C timing
  • Your PAN and residency details

Your destination country can change the details

Requirements differ from one consulate, university and visa route to the next, how recent the figures must be, how long funds must have been held, and which certificates are mandatory. We assemble the documents around the exact checklist you're applying under.

Frequently asked questions

Common questions

TDS often falls short of the real liability, for example when a buyer under-deducts on a sale or rental TDS is light. If your tax after TDS is ₹10,000 or more, the balance is advance tax, payable in instalments through the year, and shortfalls carry interest.

Not under Section 234C, if you pay the tax on that gain in the instalment after it arose or by 31 March. The 234C proviso relieves the instalment interest on a capital gain you could not have estimated earlier. But this relief is only from 234C.

No. Section 234B is separate: if your total advance tax is below 90% of the tax due, interest runs from 1 April of the assessment year regardless of the 234C relief. So a late sale where the balance was not paid can still attract 234B interest. The two are independent.

Compute the real liability, pay the tax on a late gain by 31 March to get the 234C relief, and pay any balance promptly to limit 234B. A CA times the payments and reconciles it all in the return.

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.

Advance tax threshold and instalments

Right now: Rs 10,000 of net tax liability triggers advance tax; 15% by 15 Jun, 45% by 15 Sep, 75% by 15 Dec, 100% by 15 Mar

Where it works differently

The liability arises from a capital gain late in the year
The s.234C proviso computes the instalment from the quarter the gain arose, so a March property sale does not attract interest for the earlier quarters.
Proviso to s.234C. Frequently missed, and it can save real money on an NRI property sale.
The taxpayer is a resident senior citizen with no business income
Advance tax does not apply at all.
s.207(2) is resident-only relief, so a non-resident retiree gets no such exemption.
TDS already covers the liability
No advance tax is due. For most NRIs, s.195 withholding on the gross amount over-covers it.
Advance tax is on the net liability after TDS credit.

Commonly got wrong

  • An NRI selling property must pay advance tax across all four quarters. The s.234C proviso starts the clock at the quarter the gain arose, and s.195 TDS usually already exceeds the liability.Advance tax on a capital gain is computed from the quarter the gain arose, and the section 195 TDS already deducted counts against it.
  • Retired NRIs are exempt from advance tax. The senior-citizen exemption in s.207(2) is resident-only.The senior-citizen advance-tax exemption applies to residents only.

TDS rate when buying property from an NRI

Right now: 12.5% plus surcharge and cess on LTCG

Where it works differently

The gain is short-term
TDS is at the applicable slab rate, effectively 30% plus surcharge and cess for most NRI sellers.
s.195 requires deduction at 'rates in force' for the actual character of the income.
No lower-deduction certificate is obtained
TDS applies to the ENTIRE SALE CONSIDERATION, not to the gain.
s.195 operates on the sum paid unless the AO determines otherwise. This is the whole commercial case for Form 13 / Form 128.
There are joint NRI sellers
TDS is deducted separately against each seller's PAN in their ownership proportion.
Rule 37BA. Deducting entirely against one PAN strands the other's credit.
The buyer deducts 1% under s.194-IA
Wrong section. The buyer becomes an assessee-in-default under s.201 for the shortfall plus 1% per month interest and penalty under s.271C.
s.194-IA applies only where the seller is a RESIDENT.

Commonly got wrong

  • TDS on property purchase is 1% over Rs 50 lakh. That is s.194-IA, for RESIDENT sellers only. For a non-resident seller it is s.195 at the full capital-gains rate, with no threshold.1% applies only if the seller is a resident. NRI seller means s.195 at 12.5% plus surcharge and cess on the whole consideration unless a certificate is obtained.
  • The buyer files Form 26QB. 26QB (now Form 141) is for s.194-IA. An NRI-seller purchase needs a TAN and Form 27Q (now Form 144).Buying from an NRI, you need a TAN, you deduct under section 195, and you file Form 27Q (Form 144 from 1 April 2026). Form 26QB is only for resident sellers.

TDS on rent paid to an NRI landlord

Right now: 30% plus surcharge and cess under s.195

Where it works differently

The tenant applies s.194-I (10%) or s.194-IB (5%)
Wrong section. Both are resident-payee provisions; rent to a non-resident falls under s.195.
The tenant becomes an assessee-in-default under s.201 for the shortfall.
There is no threshold
s.195 has no minimum. Even Rs 8,000 a month of rent attracts deduction.
Unlike 194-I (Rs 2.4 lakh) and 194-IB (Rs 50,000 a month).
The landlord obtains a Form 13 certificate
The AO can certify a much lower rate reflecting the 30% standard deduction and interest, often into single digits.
s.197. This is the standard fix for NRI landlords.
The tenant is an individual with no TAN
They must still obtain a TAN to deduct under s.195. This is the practical reason NRI landlords lose tenants.
s.203A.

Commonly got wrong

  • Tenants deduct 10% TDS on rent under s.194-I. That applies to resident landlords. For an NRI landlord the section is 195 at 30% plus surcharge and cess.If your landlord is an NRI you deduct under section 195 at 30% plus surcharge and cess, you need a TAN, and there is no minimum threshold. The landlord can lower it with a Form 13 certificate.
