Leveraged FCNR deposit: is the GIFT City loan interest deductible?

Yes, but only as investment interest: on a leveraged FCNR deposit, the GIFT City loan interest is an itemized deduction on Form 4952, capped at your net investment income. If you take the standard deduction, you get nothing for it, while the FCNR interest stays fully taxable. That gap decides whether the trade makes money.

How the US taxes each side of the trade

You borrowed from a GIFT City lender, added your own money, and placed a three to five year FCNR(B) deposit that the bank holds under lien as security. On your US return those are two separate items: interest you earn and interest you pay. They don't net against each other on their own.

The FCNR interest is taxed in full

As a US tax resident you report worldwide income, so every dollar of FCNR(B) interest goes on your return as ordinary interest, taxed at your marginal rate of up to 37%.

India exempts that interest for a non-resident under Section 10(15)(iv)(fa) of the Income-tax Act, 1961, carried into Schedule IV of the Income-tax Act, 2025 from tax year 2026-27. The bank deducts no TDS on it.

That exemption works against you here. With no Indian tax paid, there's no foreign tax credit to set against the US bill. It's the same position as holding an FCNR(B) deposit without a loan; the loan only adds a cost line.

The loan interest follows the money

Under the interest tracing rules in Treasury Regulation 1.163-8T, interest takes its character from what the borrowed money paid for. Loan proceeds that go straight into the FCNR deposit buy an asset that produces interest, so the GIFT City loan interest is investment interest under IRC Section 163(d).

India's exemption doesn't change that. Section 265 blocks the deduction for interest on loans used to buy tax-exempt bonds, but only where the US itself exempts the income, and FCNR interest is taxable in the US.

When the GIFT City loan interest is deductible on a leveraged FCNR deposit

Investment interest isn't an above-the-line deduction. Three conditions decide whether any of it reaches your return:

• You itemize. It goes on Schedule A, so it only helps if your itemized total beats the 2026 standard deduction of $16,100 single or $32,200 married filing jointly.
• You paid it in the year. An individual on the cash method deducts interest when it's paid, not when it accrues.
• It fits under the cap. The deduction can't exceed your net investment income, which you work out on Form 4952.

Whatever the cap blocks isn't lost. Section 163(d)(2) carries disallowed investment interest forward to later years with no time limit, and you use it once your investment income catches up.

The FCNR interest itself counts as investment income, so in a normal year the cap rarely bites. Any amount you do deduct also reduces net investment income for the 3.8% net investment income tax, if your income is high enough to owe it.

What the spread looks like after tax

Worked example: Arjun and Neha

They're US tax residents filing jointly in the 32% federal bracket. They put in $50,000 and borrowed $450,000 from a GIFT City lender for a $500,000 FCNR(B) deposit. Assume the deposit pays 6.5% and the loan costs 6.0%.

• FCNR interest: $500,000 x 6.5% = $32,500
• Loan interest: $450,000 x 6.0% = $27,000
• Pre-tax spread: $5,500, or 11% on their $50,000
• Federal tax on $32,500 at 32%, with no deduction: $10,400

What they keep depends entirely on whether that $27,000 is deductible, which depends on their other itemized deductions.

The middle row is the easiest to misread. Without the loan, that couple would take the $32,200 standard deduction anyway, so only the $14,800 by which their itemized total clears it does any work.

I'd want anyone considering this structure to see the after-tax row, not the 11%. On the standard deduction, Arjun and Neha would need roughly 7.9% on the deposit just to break even, above the rates banks offered during the RBI's 2026 swap window. State income tax on the FCNR interest widens the gap further.

The timing trap when interest rolls up to maturity

Many of these structures settle the loan from the deposit at maturity, so you pay nothing out of pocket along the way. That convenience can put the income and the deduction in different tax years.

For a deposit with a term over one year, IRS Publication 550 treats the interest as original issue discount. You include part of it in income each year, even if the bank pays it all at maturity.

If the loan interest is capitalised and settled only at the end, it's deductible only in that final year.

The result is three or four years of fully taxed FCNR interest with no deduction. Then comes one large deduction that the net investment income cap mostly blocks, because the earlier years' deposit interest has already been counted. The excess carries forward, but you need future investment income to use it.

Before your first return, check three things in the paperwork:

• Whether the loan interest is paid monthly or quarterly, or added to the loan balance.
• Whether the FCNR(B) deposit pays out interest or reinvests it to maturity.
• Whether the borrower on the loan matches the depositor on the FCNR, especially on joint accounts.

A payout deposit that services the loan each quarter avoids the trap, since income and deduction then land in the same year.

Who this applies to

The question only matters if the US taxes your worldwide income:

• US citizens and green card holders, wherever they live.
• Resident aliens under the substantial presence test, which covers most H-1B and L-1 holders.
• The US-resident part of a dual-status year when you move.

If you've moved back to India and are now a nonresident alien for US purposes, FCNR interest is foreign-source income outside US tax, so there's nothing to deduct against. The same is true for an NRI in Dubai or Singapore with no US status at all.

What to do before you file your 2026 return

The RBI's swap facility let banks swap fresh three to five year FCNR(B) dollars into rupees with the RBI, and that deposit window closed on 30 September 2026. If you placed one of these, your 2026 return is the first to show it.

1. Pull the loan agreement and the deposit advice, and note when each one pays interest.
2. Add up your other itemized deductions to see whether you'll clear $16,100 or $32,200.
3. Report the full FCNR interest on Schedule B, and include the deposit at its gross value when you report Indian deposits on FBAR and Form 8938. The loan doesn't reduce it.
4. If you itemize, complete Form 4952 and keep the GIFT City statements showing interest actually paid, because the tracing rules put the burden on you to show where the money went.

The judgment call worth paying for is the multi-year view: whether carried-forward interest will ever be usable given your other investment income, and how a move to India mid-tenure changes the picture.

Rebuild the table above with your own deposit rate, loan rate and itemized deductions before you file your 2026 return. It takes ten minutes and tells you whether the spread survives tax.

If you're on the standard deduction, I'd treat this structure as costing money after tax, and weigh that before any renewal or rollover. If carryforwards or a move year complicate the answer, InvestMates can run the multi-year US and India projection with you.
