A practical, research-backed guide for NRIs in the US comparing the 401(k) and India's National Pension System (NPS) — covering eligibility, tax implications, FBAR rules, DTAA benefits, and who should invest in what.
You've been maxing out your 401(k) every year, watching your retirement corpus grow in USD. Then someone in your WhatsApp group says: "Yaar, open an NPS account too — double benefit!"
Should you? The honest answer is: it depends on where you plan to spend your retirement years. For NRIs living in the US, the 401(k)-vs-NPS question has a clear answer in most cases — but there are important exceptions. Here is everything you need to know before making that call.
What Is a 401(k)?
A 401(k) is an employer-sponsored retirement savings plan in the United States. You contribute a portion of your pre-tax salary, your employer often matches a percentage of that contribution, and the entire corpus grows tax-deferred until you withdraw it in retirement.
Key 401(k) facts for 2025/2026:
- Annual contribution limit: $23,500 (under 50)
- Catch-up contributions (age 50+): An additional $7,500 = $31,000 total
- Super catch-up (age 60-63): An additional $11,250 = $34,750 total
- Employer match: Typically 3–6% of salary — this is essentially free money
- Tax treatment: Pre-tax contributions reduce your US taxable income today; withdrawals in retirement are taxed as ordinary income
- Early withdrawal penalty: 10% penalty + income tax if you withdraw before age 59½
- Investment options: US mutual funds, ETFs, index funds, bonds

What Is NPS?
India's National Pension System (NPS) is a government-backed retirement savings scheme regulated by the Pension Fund Regulatory and Development Authority (PFRDA). Originally launched for government employees in 2004, it opened to all Indian citizens — including NRIs — in later years.
NPS has two account tiers:
- Tier I (Pension Account): Mandatory for NPS. Locked until age 60, with limited partial withdrawals allowed.
- Tier II (Investment Account): Voluntary savings account with no lock-in. NRIs are not eligible for Tier II.
Key NPS facts for 2026:
- Minimum annual contribution: ₹1,000 (Tier I)
- Returns: 9–15% historically, depending on fund choice and asset allocation
- Investment options: Equity (E), Corporate bonds (C), Government securities (G), and Alternative assets (A)
- Tax deduction in India: Up to ₹1.5 lakh under Section 80CCD(1) and an additional ₹50,000 under Section 80CCD(1B)
- At maturity (age 60): Up to 60% as a tax-free lump sum in India; at least 20% must purchase an annuity (pension income, taxable in India); remaining 20% can now also be withdrawn as lump sum per the late 2025 PFRDA amendment
- Big 2025 update: PFRDA removed the requirement to visit India to open an NPS account — full digital onboarding is now available from anywhere in the world

Can NRIs in the US Legally Invest in NPS?
Yes — NRIs, OCIs (Overseas Citizens of India), and PIOs can all invest in NPS, subject to the following conditions:
- Age: You must be between 18 and 70 years old.
- KYC compliance: PAN card and OCI/passport documents are required.
- Bank account: Contributions must come from an NRO account, not directly from a US bank account. You cannot fund NPS from overseas income directly under FEMA rules.
- Tax deduction eligibility: The Section 80CCD deductions are only useful if you have taxable income in India. If your only income is US-sourced, these deductions give you no benefit.
As of December 2025, PFRDA allows 100% digital KYC — Indian passport holders and OCI card holders can complete the entire account-opening process online without visiting India. Address proof can include an overseas residence permit, work permit, or foreign driving license, attested by the Indian Embassy or a local notary.
How Is NPS Taxed in the US?
This is where things get complicated for NRIs in the US — and where many make costly mistakes.
The core problem: NPS is not a "qualified retirement plan" under US tax law. The IRS does not recognise NPS the way it recognises a 401(k), IRA, or even a foreign pension from certain DTAA countries.
Here is what that means practically:
During Accumulation
- In India, NPS contributions and growth enjoy Exempt-Exempt-Exempt (EEE) treatment.
- In the US, that EEE treatment does not apply. NPS investment gains may be taxable in the US in the year they are earned, not just at withdrawal. This is a significant hidden cost.
At Withdrawal
- Lump sum (60% of corpus): Tax-free in India. But the IRS may treat this as ordinary income in the US. There is no US exemption that mirrors India's 60% lump-sum rule.
- Annuity income: Taxable as income in India (TDS at 31.2% for NRIs by default). The same pension income is also reportable in the US.
DTAA Relief
India and the US have a Double Tax Avoidance Agreement. Under Article 20/21 of the India-US DTAA, pension and annuity income is generally taxable in the country of residence (USA). To claim this:
- You need a Tax Residency Certificate (TRC) from the US IRS
- Submit Form 10F to the Indian deductor before payouts begin
- File Indian tax returns to claim refunds on excess TDS
The DTAA can significantly reduce double taxation on annuity income — but it requires proactive paperwork, not just goodwill.

Do NRIs Need to Report NPS Under FBAR or FATCA?
This is the question most NRI investors ignore — and it can result in steep penalties.
FBAR (FinCEN Form 114)
US persons must file an FBAR if the aggregate value of all foreign financial accounts exceeds $10,000 at any point during the year. Whether NPS constitutes a "financial account" under FBAR is a gray area in tax law. Many tax advisors take the conservative position that NPS should be reported to avoid penalties.
The penalty for wilful non-disclosure: up to 50% of the account balance per year or $100,000, whichever is greater.
FATCA (Form 8938)
Under FATCA, US taxpayers must report specified foreign financial assets on Form 8938 when total value exceeds:
- $50,000 (single filer, year-end) or $75,000 (single filer, at any point in the year)
- $100,000 (married filing jointly, year-end)
NPS, as an Indian financial asset, likely falls within the FATCA reporting scope.
Bottom line: If you hold an NPS account as a US resident, discuss FBAR and FATCA disclosure obligations with a cross-border tax advisor. The risk of non-disclosure far outweighs the cost of professional advice.

Which Gives Better Returns: 401(k) or NPS?
On paper, NPS historical returns of 9–15% look attractive. But the comparison is more nuanced:
401(k) Returns
- Invested in US equity markets (S&P 500 index funds typically)
- Historical average: ~10–11% annually (long-term S&P 500 average)
- Returns are in USD — the world's reserve currency
- Employer match immediately boosts effective returns by 3–6%
NPS Returns
- Equity-heavy NPS funds have historically returned 9–15%
- Returns are in INR — which has historically depreciated ~3–4% annually against the USD
- Real USD-adjusted return: Subtract INR depreciation from NPS returns, and the effective USD yield narrows considerably
- No employer match
Example: An NPS equity fund earning 12% in INR, after a 3.5% annual INR depreciation, translates to roughly 8–8.5% in USD terms. A 401(k) in an S&P 500 index fund with employer match can easily outperform this.
The 401(k) wins on risk-adjusted USD returns for NRIs staying in the US.
Should You Invest in NPS If You Plan to Stay in the US?
Verdict: Prioritise your 401(k). NPS adds complexity without proportionate benefit.
Here is why:
- Your retirement expenses will be in USD, not INR
- NPS's India tax deductions are useless if you have no Indian taxable income
- US tax treatment of NPS growth and withdrawals is unfavourable
- FBAR/FATCA compliance adds annual reporting burden
- INR depreciation erodes real USD returns over a 20-30 year horizon
- Your entire financial life is US-anchored; a separate Indian retirement account creates currency and administrative risk
What to do instead:
- Max out your 401(k) — especially up to the full employer match
- Contribute to a Roth IRA ($7,000/year if eligible; $8,000 if 50+)
- Open a Health Savings Account (HSA) if you have a high-deductible health plan
- Invest in taxable brokerage accounts for additional savings
Should You Invest in NPS If You Plan to Return to India?
Verdict: Yes — NPS makes sense as a supplemental India retirement corpus.
If you are planning to move back to India in 10-15 years, NPS serves a meaningful purpose:
- You will have INR expenses in retirement — an INR corpus is actually an asset, not a liability
- NPS gives you tax-deferred growth in India's equity and bond markets
- The 60% tax-free lump sum at maturity is a genuine benefit if you are an Indian resident at withdrawal
- India's equity markets are in a long-term structural growth phase
- NPS is government-regulated, low-cost (fund management fees as low as 0.09%), and portable
Strategy for return-planners:
- Keep funding your 401(k) — at minimum up to employer match
- Open NPS with a moderate contribution (₹5,000-₹10,000/month via NRO account)
- Choose an aggressive Tier I allocation (75% equity via Auto or Active choice) when young
- Plan your NPS exit to coincide with your return to India — your RNOR (Resident but Not Ordinarily Resident) window gives you a tax-efficient exit opportunity
Can You Invest in Both?
Yes, and for many NRIs with a clear India return plan, a both-and strategy makes sense — not either-or.
Suggested allocation framework:
| Profile | 401(k) Priority | NPS Priority |
|---|---|---|
| Long-term US settler | High | Low / Skip |
| Planning return in 5-10 years | High | Moderate |
| Planning return in 10+ years | High | Low-Moderate |
| Already contributing from pre-NRI days | High | Maintain, don't add aggressively |
The key is to never let NPS become a drain on funds you should be putting into your 401(k) — especially if your employer offers matching.
Never leave employer match on the table. That is a 50-100% instant return on your contribution that no Indian pension scheme can replicate.
The Bottom Line
For most NRIs in the US, the 401(k) wins — and it is not close. Employer matching, US tax deductions, clean IRS compliance, and USD-denominated growth make it the superior retirement vehicle for anyone whose life is anchored in America.
NPS is a useful tool with one specific use case: building a retirement corpus in India if you genuinely plan to return. It is low-cost, government-backed, and gives you a real INR asset. But for NRIs who are US-long-term or unsure about their return plans, the FBAR complexity, absence of US tax benefits, and currency risk make NPS a hard sell as a primary retirement strategy.
Start here:
- Max out your 401(k) up to the employer match — every year, without exception
- If you plan to return to India, add NPS as a supplemental contribution via your NRO account
- Consult a cross-border tax advisor for FBAR/FATCA compliance before opening NPS
Your retirement is too important to wing it across two tax systems.
