Selling an Indian mutual fund while you are a US taxpayer? See the US tax under the PFIC rules, lot by lot: the gain in dollars, the tax for each year you held, the IRS interest charge and the effective rate. Import your CAS or type in your purchases.
For US citizens, green card holders and US tax residents (most H-1B workers), using section 1291 with no election. Everything runs in your browser. For education only, not tax advice.

How this is worked out. Each purchase's gain in dollars is spread evenly over the days you held it. This year's share is ordinary income at your bracket. Each earlier year's share is taxed at that year's top rate (37% since 2018), plus IRS interest compounded daily from that year's due date to this year's. Rupees are converted at the Federal Reserve's rate on each purchase and sale date.
Section 1291 (excess distribution) treatment, with units matched first-in, first-out. Exchange rates: Federal Reserve H.10 daily rates; a day without a rate takes the previous business day's. IRS interest after the last published quarter, October to December 2026, assumes the rate stays at 7%. Distributions from dividend (IDCW) plans, the mark-to-market election and Indian tax credits are explained below but not computed here.
Not a capital gain
Under section 1291 the gain is spread over every day you held the units. The share for earlier years is taxed at the top rate, 37%, plus interest.
Rupee gains become dollar gains
Cost at the rate on the purchase date, proceeds at the rate on the sale date. A weaker rupee can turn a 60% rupee gain into about 33% in dollars.
Each purchase stands alone
Every SIP instalment is its own lot with its own holding period. Units are sold oldest first, and a losing lot does not offset a winning one.
Form 8621 for every fund
In a year you sell, each fund needs its own Form 8621, however small. Your funds also count toward FBAR and Form 8938.
Frequently asked questions
Are Indian mutual funds PFICs?
Yes. US tax practice treats an Indian mutual fund as a foreign corporation, and almost all of its income and assets are passive, so every Indian fund, equity, debt, hybrid or index, is a passive foreign investment company (PFIC) for a US taxpayer. That includes citizens, green card holders and residents under the substantial presence test, which covers most H-1B workers.
How is the US tax worked out when I sell?
Unless you made an election, section 1291 applies. Your dollar gain on each purchase is spread evenly over every day you held it. The part that falls in the year of sale is ordinary income at your normal rate. Each earlier year's part is taxed at the highest rate for that year, 37% since 2018, and an interest charge is added as if that tax had been paid late, at the IRS underpayment rate compounded daily from that year's due date.
Why is the tax so much higher than on a US fund?
Three things stack up. There is no 15% or 20% long-term capital gains rate, most of the gain is taxed at 37% whatever your bracket, and the interest charge grows the longer you held. A fund held for five years can lose 40% or more of its dollar gain to US tax, against 15% for a US fund.
Is the gain worked out in rupees or dollars?
Dollars. The cost of each purchase is converted at the exchange rate on the day you bought, and the sale at the rate on the day you sold. A falling rupee shrinks the dollar gain: a fund up 60% in rupees while the rupee went from 73 to 88 to the dollar is up only about 33% in dollars. This calculator uses the Federal Reserve's daily rate; any consistent, reasonable source is generally accepted.
What happens to a loss?
Section 1291 applies only to gains. Each purchase is worked out on its own, and the Form 8621 instructions say a loss does not reduce the gain subject to section 1291, so a losing purchase does not offset a winning one. The loss itself is generally a capital loss under the normal rules, which you report on Form 8949.
I bought units before I moved to the US. Do those years count?
The holding period still starts on the day you bought; there is no fresh start when you arrive. But the IRS's 1992 proposed regulations say a fund is not a PFIC for you on the days before you became a US person. Those days' share of the gain is ordinary income in the year of sale, with no 37% tax and no interest, and the year you arrived splits by day. Those regulations were never finalized, and the law read strictly counts every day. Enter the date you became a US person to see both.
Does switching plans or moving back to India count as selling?
A switch from one scheme or plan to another, including regular to direct, is a sale and a new purchase, so section 1291 applies to any gain. Gifting units also counts as a disposition. The 1992 proposed regulations would also treat ceasing to be a US person, for example moving back to India, as selling on your last day as a US person.
Do I have to file Form 8621 every year?
You file one Form 8621 for each fund in any year you sell units at a gain or receive an excess distribution, whatever the amount. In other years, a fund with no election can be left off if all your PFICs together are worth $25,000 or less on 31 December ($50,000 on a joint return). Missing a required Form 8621 keeps your whole return open to IRS assessment until it is filed. The funds still count toward FBAR and Form 8938.
What about the mark-to-market and QEF elections?
Indian fund houses do not issue the PFIC annual information statement a qualified electing fund (QEF) election needs, so QEF is effectively unavailable. Mark-to-market is generally considered available for open-ended schemes, which are redeemable at a published net asset value, though no ruling confirms it. You then pay ordinary income tax each year on the rise in value, with no interest charge, and can deduct a fall up to earlier inclusions. Elected after the first year, the gain to date still goes through section 1291 that year. This calculator does not compute it.
Does the Indian tax I paid reduce the US tax?
Not the PFIC tax and interest. Indian tax on a redemption gain cannot reduce the deferred tax for earlier years; that relief applies only to tax on distributions. It can be claimed as a foreign tax credit on Form 1116 in the year of sale, but the gain is usually US-source, so the credit is often limited unless the India-US treaty's resourcing rule is used. This calculator shows the US tax before any credit.
Is my CAS uploaded anywhere?
No. The PDF is opened and read in your browser, and your purchases never leave your device. Use the detailed CAS from CAMS or KFintech, which lists each transaction; the summary CAS has balances only.

Disclaimer: This calculator is for educational purposes only and does not constitute tax advice. It applies section 1291 with no election, ignores foreign tax credits and distributions from dividend (IDCW) plans, and uses the top rate for each prior year. PFIC reporting is complex; speak to a qualified tax professional before filing.
