Don't Start an Indian SIP Before You Understand PFIC

1. What PFIC is, and why it matters

PFIC stands for Passive Foreign Investment Company. It is a US tax classification for certain foreign companies and investment vehicles. Under US rules, a foreign corporation can generally be a PFIC if it meets either of two tests: the 75% income test (75% or more of its gross income is from passive sources) or the 50% asset test (50% or more of its assets produce, or are held to produce, passive income).

You do not need to memorise the tests. What matters for an NRI is understanding whether you are likely to encounter a PFIC at all — and for a US taxpayer buying Indian pooled investments, the answer is frequently yes.

2. The two groups it catches

This is not only an issue for people currently living in the US. It becomes an important issue after you move back to India. There is a second group that often gets completely overlooked: US-born kids who move to India with their parents. If your child is a US citizen, their US tax status does not disappear because they now live in India — and an Indian mutual fund bought in the child's name can be a PFIC for the child.

3. The SIP trap: New Jersey to Hyderabad

Say you move from New Jersey to Hyderabad. You become an Indian resident, but you still have a US tax filing obligation because you are a US citizen or a green-card holder. You go to an Indian bank or investment platform and say you want to start a £50,000 SIP every month. You pick a few popular Indian mutual funds. Nothing unusual from an Indian lens.

From a US tax lens, an India-domiciled mutual fund can generally be a PFIC. Suddenly what looked like a simple SIP has created a completely different US tax reporting and filing issue. This is probably one of the biggest PFIC traps for NRIs returning to India.

And it is not limited to one type of fund. You need to look at the structure of the investment: Indian equity mutual funds, debt mutual funds, certain ETFs, commodity or gold funds, other pooled foreign investment vehicles, and even some insurance-linked or investment products can create separate US tax complications.

4. Indian stocks vs mutual funds — domicile decides

A foreign company is not automatically a PFIC just because it is foreign. Suppose instead of a mutual fund you directly buy shares of an Indian operating company — say Infosys or HDFC Bank. That is generally not a PFIC, because the test depends on the company's income and assets, not its nationality. A common rule of thumb: foreign individual stocks are usually not PFIC, while foreign mutual funds often are.

The distinction that matters even more is where the fund is domiciled versus what it invests in. You want exposure to Indian stocks — you have two ways to get it. You can buy an India-domiciled mutual fund, or you can buy a US-domiciled ETF that invests in Indian companies. These two can have very different US tax consequences, because from a US tax perspective the domicile and legal structure of the investment matter.

So when someone says "I want Indian exposure", that is not enough information. The next question is always: how are you going to get that exposure?

5. The Section 1291 tax trap

People are scared of PFIC because the US does not necessarily treat the investment like your normal stock investment. Under the default PFIC rules (Section 1291), certain gains can be subjected to what is known as the excess-distribution regime — and this is where it gets ugly.

Imagine you invested £10 lakhs in an Indian mutual fund. Several years later it is worth £20 lakhs. You naturally think, "I have a gain of £10 lakhs, so I will pay capital gains on that £10 lakhs." PFIC taxation can be much more complicated. Certain gains can be allocated across different holding periods, potentially resulting in ordinary income treatment for part of the gain plus an interest charge (a deferred-tax interest penalty). The result can be a tax calculation dramatically different from what you expected.

That is one of the biggest reasons people say PFIC is something you plan before you invest, not after you sell.

6. Reporting: Form 8621

There is a reporting requirement many people don't know about: PFIC investments generally require IRS Form 8621. If you have accumulated multiple mutual funds over several years, this becomes a significant compliance exercise.

Imagine five mutual funds, monthly SIPs, multiple purchases, dividends and redemptions — now imagine doing that year after year while trying to figure out the US tax treatment. PFIC is not a simple question of how much tax you will pay. It is also a compliance and record-keeping issue.

7. US-born kids moving to India

This is where parents returning to India need to pay attention. You move back with your family; your kids were born in the US and are US citizens. You open an investment in India for them — maybe £10,000 or £20,000 a month in a mutual fund for their future. If that child is a US citizen, their US tax status does not disappear because they live in India. If you buy an India-domiciled mutual fund in the child's name, you may have created a PFIC issue for your child.

And here is the part many parents don't realise: the problem can follow the child for years. They may be 8 today, but by the time they reach 18 or 21, the investment can have a substantial value and a long history of transactions. What looked like a simple investment made for your child can turn into a complex US tax and reporting issue later.

8. Investments you already own

Now flip it around. Maybe you already had investments in India before moving to the US — say £20 lakhs sitting in Indian mutual funds. You move to America and become a US tax resident, even if you are not a US citizen or green-card holder. What happens now?

This is where you need to look at the history of the investment: when did you buy it, what was your tax status at the time, what happened while you were a US taxpayer, did you have any distributions, have you redeemed anything, and what reporting was required? Do not assume that because you bought it before moving to the US, PFIC rules do not apply. The analysis can be more complicated, and this is exactly the situation where you want someone who understands both US and Indian taxation to look at the actual investment history.

9. Plan before the move, not after you land

When you are planning to return, don't wait until you land in India to think about PFIC. Let's say you're moving in 2027. You already have a US portfolio and you know you will need Indian investments after you move. Now is the time to ask: what will my US tax status be after I move? Am I a US citizen, a green-card holder, or going to be a US tax resident? Am I going to give up my US status? These questions can dramatically change the analysis.

Technically there are two other ways PFICs can be taxed: the QEF (Qualified Electing Fund) election and mark-to-market. These can produce different outcomes. But here is the practical point: you can't simply say "I'm going to choose QEF and that solves the problem." The investment needs to provide the information required to make that election, and many foreign funds don't provide the US tax information. Mark-to-market has its own eligibility requirements. That is another reason choosing the investment first and figuring out the US tax treatment later is a bad strategy.

10. The six questions to ask before investing

If you are a US taxpayer living in India, living in the US, or planning to move back, ask these questions before buying any Indian investment:

When you live in the US you think about investments through a US tax lens; when you move to India you naturally switch to an Indian tax lens. But if you are still a US taxpayer, you have to think through both lenses at once. An investment that looks completely normal in India can have a very different US tax treatment. And this applies not just to you — it can apply to your spouse and to US-citizen children growing up in India.

11. TL;DR

An India-domiciled mutual fund SIP can be a US Passive Foreign Investment Company. If you are still a US taxpayer — including US-born kids living in India — US rules may tax it under the Section 1291 excess-distribution regime (ordinary income plus an interest charge) and require Form 8621. Foreign individual stocks are usually not PFIC, and US-domiciled ETFs are not the same as India-domiciled funds. Elections like QEF and mark-to-market depend on the fund providing data, which many funds don't. And investments you bought before moving to the US can still become a problem. Don't open the SIP first and call the CPA later. Understand your tax status, understand the investment, and decide where and how you want to invest before you move.
