This question comes up in our community almost every single week.
“Should I invest in India or keep my money in the US? Where will I grow my wealth faster over 20 years?”
I used to think the answer was about returns. Which market goes up more.
After helping thousands of NRIs since 2017, and after fumbling through my own move back in 2017, I can tell you something that might surprise you.
For an NRI, returns are almost the least important part of this decision.
Let me explain why, and then I will give you a simple way to actually decide.
What you will learn here
- What the long-term return numbers really say (with data)
- Why those numbers are not the deciding factor for NRIs
- The PFIC trap that quietly eats US-based NRIs alive
- A US estate tax rule almost nobody warns you about
- How to actually choose, based on where your life is heading
- What changes if you are planning to move back to India
Let us start with the part everyone fixates on.
The returns: closer than you think
People imagine one market is a rocket and the other is a snail. The real data is far more boring, in a good way.
Here is roughly what the long-term numbers look like, based on data through early 2026.
| Period | India (Nifty) | US (S&P 500) |
|---|---|---|
| Last 20 years | ~11.5% a year | ~10.7% a year |
| Last 10 years | ~11.7% a year | ~14.8% a year |
| 30 years (in US dollars) | ~8.3% a year | ~8.3% a year |
Look at that bottom row.
Over 30 years, when you measure both in US dollars, India’s broader market and the S&P 500 land almost exactly on top of each other. The gap is a fraction of a percent.
In rupee terms, India often looks better. In dollar terms, the rupee falling against the dollar (historically around 3 to 4% a year) eats into India’s lead, and the two even out.
So please hear me on this.
Neither market is going to make you rich while the other makes you poor. Both have built serious wealth for patient long-term investors. The “winner” flips depending on which decade and which currency you pick.
That is exactly why returns should not be the thing you decide on. They are too close to call, and nobody can predict the next 20 years anyway.
So what should you decide on? Three things: the currency your goals are in, the tax you actually pay, and the paperwork headache you take on.
Decision 1: What currency are your future goals in?
This is the single most useful question, and most people skip it.
Your investments should roughly match the currency you will spend in.
If your big future expenses are in India:
A home in Bengaluru. Your kids studying in India. Retiring in India near your parents. Supporting family.
Then rupee assets make sense. You avoid the risk of saving in dollars and watching the rupee move against you right when you need to convert. Our cost of living India vs USA breakdown helps you size up what those Indian expenses actually look like.
If your big future expenses are in dollars:
US college for your kids. A life you might keep partly in America. The genuine possibility you stay abroad.
Then dollar assets make sense. Keeping your money in the currency you will spend protects your purchasing power.
When I was deciding, my honest answer was “my life is moving to India”. That clarity made the investment question much simpler than all the return charts ever did.
If you are genuinely unsure where you will end up, splitting across both is a perfectly reasonable answer. Many planners suggest keeping some meaningful slice abroad purely for currency diversification.
Decision 2: The tax reality (this is where it gets real)
Here is the part bankers and finfluencers gloss over.
“India gave higher returns” means nothing if your home country taxes those returns harder.
And for US-based NRIs especially, the tax structure quietly pushes you toward some choices and away from others.
Let me walk through the big ones.
The PFIC trap (US-based NRIs, please read this twice)
If you are a US person for tax purposes (citizen, green card holder, or US tax resident) and you buy Indian mutual funds, you have likely walked into something called PFIC.
The IRS treats most Indian mutual funds, index funds, ETFs, and ULIPs as Passive Foreign Investment Companies.
Under the default PFIC rules, your gains can be taxed at the highest ordinary income rates, plus interest charges for the years the money sat in the fund. Combined with Indian tax, the effective rate can climb past 50% in bad cases. You also have to file a separate Form 8621 for every single fund, every year, even if you made nothing.
Here is the cruel part. Reporting the dividend on your return does not satisfy the PFIC requirement. People think they are compliant when they are not.
The way out that most cross-border CPAs point to:
- Direct Indian stocks do not trigger PFIC. Individual shares are clean.
- US-domiciled India ETFs (the kind that trade on US exchanges) give you India exposure without the PFIC headache.
- GIFT City funds can sidestep PFIC too, though there is a catch I will mention below.
If you are sitting on Indian mutual funds and you are a US person, do not panic, but do get them reviewed properly. Our notes on capital gains for NRIs and disclosing foreign assets give you the lay of the land, and you will also want to understand FBAR reporting for your Indian accounts.
The US estate tax trap (almost nobody warns you)
This one genuinely shocks people.
If you are not a US citizen or US domiciliary, and you hold US-situated assets (like US stocks) above a fairly low threshold, your estate can face US estate tax of up to 40% on the amount over it.
The exemption for non-US-domiciled individuals is far smaller than the millions that US citizens get. Please treat this as a flag to verify with a cross-border advisor, not as exact numbers, because the thresholds and your domicile status need real analysis.
The point is simple. A US-based NRI loading up on US stocks needs to think about more than returns. There can be a serious estate-side cost that a resident American never has to think about.
The Gulf advantage
If you live in the UAE or another zero-tax country, you are in the best seat in the house.
Indian investments can be genuinely tax-light for you, because there is no second layer of home-country tax. GIFT City funds, NRE deposits, all of it works cleanly with no PFIC-style monster waiting.
For a US NRI, GIFT City is double-edged. Zero Indian tax sounds great, but it also means zero foreign tax credit to offset your US bill, so you pay full US tax anyway. For a UAE NRI, zero tax on both sides is just zero tax. Same product, very different outcome.
The double-tax safety net
Whatever you hold, the India-US tax treaty (DTAA) is what stops the same income being taxed fully in both countries. If India already took TDS, you can usually claim that as a credit against your US bill. Our DTAA explainer walks through how this actually works for folks in the US.
Decision 3: The paperwork you are signing up for
This is the quiet tax. The tax on your time and peace of mind.
Investing in India from abroad means TDS, Indian ITR filing, tracking holding periods under two different rule books, and reporting forms back home. Before you remit money in, it is also worth knowing about TCS on remittances so nothing surprises you.
Investing in the US is usually simpler from a reporting view if you live in the US, but adds the estate-tax angle and currency mismatch if your life is heading to India.
There is no zero-effort option here. Just pick the effort you would rather carry.
So, India or US? A simple way to decide
Forget the return charts for a minute. Run yourself through this.
- Where will I spend most of my money in the next 10 to 20 years? Match your currency to that.
- What does my country of residence do to these gains? US person plus Indian mutual funds is a red flag. Fix the vehicle, not just the country.
- How much paperwork am I willing to handle? Be honest with yourself.
- Am I diversified, or am I betting the house on one market because a chart looked exciting?
For a lot of our US-based members, the practical answer ends up being: keep a strong US base for US-currency goals, get India exposure through direct stocks or US-listed India funds rather than Indian mutual funds, and keep NRE deposits and rupee assets sized to your India goals.
For Gulf members, the answer often tilts more comfortably toward India, because the tax friction simply is not there.
There is no universal winner. There is only the right answer for your life. If you want a wider menu of what is actually available to you, our guide on best investment options for NRIs lays them out, including SIPs, fixed deposits, and real estate.
What changes if you are moving back to India?
A lot, and mostly in your favour, if you time it.
When you return, you usually get an RNOR window of about 2 to 3 years (Resident but Not Ordinarily Resident). During this time, your foreign income generally stays outside the Indian tax net. It is a soft landing before full residency kicks in.
This window is gold for restructuring your portfolio. It is often the cleanest time to sell US assets, move money, and reshape things before India starts taxing your global income. Please read our RNOR guide before you make any big moves, because the timing of your return date alone can change your tax for years.
A few things to map out before you land:
- Your US retirement accounts. The 401(k) and IRA treatment after you move is its own subject, so plan it early.
- Converting your accounts. Your NRE accounts get redesignated, and an RFC account is often where returning NRIs park foreign currency.
- A clear sequence for everything. Our return financial checklist keeps it from becoming chaos, and the wider moving back from the USA guide covers the rest.
Frequently asked questions
Has India or the US given better returns historically?
It depends entirely on the period and currency. In rupee terms India usually looks better. In dollar terms over very long stretches, the two are remarkably close. Over the last decade, US indices have edged ahead in dollar terms.
I am a US green card holder. Can I just buy Indian mutual funds?
You can, but you probably should not without advice. Most Indian mutual funds are PFICs under US law, which can mean punitive tax and a separate filing for each fund every year. Direct Indian stocks or US-listed India funds are usually cleaner.
Does rupee depreciation mean US investments are always better for NRIs?
No. A falling rupee raises the rupee value of your US assets, but it also reduces the dollar value of your India returns. The net effect depends on how the markets perform versus the currency. It is not a free win either way.
I live in Dubai. Is India a better bet for me than for a US-based NRI?
From a tax-friction standpoint, often yes. With no home-country tax layer, Indian investments and GIFT City products work much more cleanly for Gulf NRIs than for US ones.
Should I just split 50-50 between India and the US?
There is nothing wrong with splitting if you are genuinely unsure where your life will land. The exact ratio should follow your goals and currency needs, not a round number that feels balanced.
I am returning to India in two years. Where should I invest now?
Lean toward not creating new tax headaches just before a move, and protect your RNOR window. This is exactly the kind of thing worth talking through with someone who has done it, and ideally a cross-border tax advisor.
A final word from me
I know you came here hoping I would point at one market and say “this one wins”. I am not going to, because that would not be honest.
The returns are close enough that they are not your real decision.
Your real decision is about where your life is heading, what your home country does to your gains, and how much paperwork you want to carry. Get those three right and the India-versus-US question mostly answers itself.
And please do not make a big cross-border money decision alone in your head at midnight. Talk to people who have actually walked this path.
