Tax-free Fixed Income Investments to maximize for Indians returning from USA
- 3 days ago

If you are an NRI planning to move back to India, the years around your return are a rare tax-planning window.
While you are still a non-resident and for the Resident but Not Ordinarily Resident (RNOR) period of up to three years after you land, your foreign income largely sits outside the Indian tax net.
Pair this window with US instruments that are themselves built to defer or avoid US tax, and you can earn solid dollar returns while paying tax in neither country.

This note covers three such instruments. From safest to riskiest: BOXX, FCNR(B) deposits, and STRC (plus two more low risk dollar options, US Treasuries and municipal bonds).
One principle to keep in mind “Tax free” is not the same as “risk free.” These three instruments sit at very different points on the risk scale. BOXX and FCNR are genuinely defensive while STRC is a high yield, higher risk instrument that happens to be tax efficient. Match each to the right sleeve of your portfolio, not just to its headline yield. |
Reyman Tip — The RNOR window can shelter far more than your defensive investments. It can also reset the cost base on your US shares and funds so years of capital gains escape Indian and US tax. See how here: US to India: huge tax savings on capital gains.
1. BOXX: Treasury like dollar returns, tax-deferred
BOXX (the Alpha Architect 1–3 Month Box ETF) invests in “box spreads” on S&P 500 Index options.
This is four legged option positions that lock in a fixed payoff at expiry, one to three months out.
The result behaves like a short-term Treasury bill: a known return with essentially no credit or market risk if held to maturity.
The fund has grown to roughly $11.4 billion in assets (May 2026) and has tracked T-bill like yields of around 4%.
The tax trick: BOXX is built to defer, not distribute. Instead of paying out taxable interest like a money market fund, it reinvests its income and flushes accumulated gains out through in kind redemptions.
You receive no taxable distributions, the fund’s NAV simply rises. You owe nothing until you sell and then it is taxed as a capital gain, not interest.
Why this matters for a returning NRI: because the gain is deferred, you choose the year you realise it.
Sell while you are still NRI or RNOR and the capital gain is foreign source income that India generally does not tax. If you have also exited US tax residency by then, a non resident alien typically pays no US tax on the sale of a US listed ETF either (unless present in the US 183+ days that year). Used well, the gain can escape tax on both sides.
The BOXX risk: reclassification BOXX’s benefit rests on its returns being treated as deferred capital gains. The IRS could treat box-spread returns as ordinary interest income. If reclassified, a US person would pay ordinary rates up to 37% (vs ~20% on long-term gains), a non-resident alien could face up to 30% US withholding on the interest, reduced to 15% under the US–India treaty with a Form W-8BEN. Realising inside the NRI/RNOR window is the best hedge against this. |
2. FCNR(B) — 6–7% in USD, tax free in India (potentially tax free worldwide)
The RBI recently opened a special foreign-currency swap window, absorbing banks’ hedging cost on fresh 3–5 year FCNR(B) deposits booked up to 30 September 2026 31 August 2026 (the window has been cut short by the RBI so move quickly on this).
USD FCNR rates jumped from 2.5–3.5% to 6% to over 7% — with no currency risk (you deposit dollars and are repaid in dollars) and interest that is tax free in India for non residents.
We covered this in depth in our dedicated article, FCNR Deposits Are Suddenly Paying 6–7%: What Every NRI Needs to Know (including the full bank by bank rate table and how FCNR compares with US HYSAs, CDs and Treasuries). The short version for this article:
Book before you land. You must be an NRI to open an FCNR deposit. Lock a five year tenure while still abroad to carry today’s elevated rate for years.
Tax-free through RNOR. FCNR (and RFC) interest is exempt under Section 10(15) while you are NRI and during your RNOR years after returning.
Time limited rates. The elevated pricing is tied to the RBI window closing 31 August 2026, the high rates are unlikely to last beyond it.
Reyman Tip — The play for FCNR is that once you become a Non Resident Alien, USA will not tax your FCNR interest. And India will not tax you during the Non Resident/ RNOR period. So you can earn dollar interest without paying taxes anywhere in the world.

3. STRC: 11.5% “return of capital” dividends, untaxed today
STRC is Strategy’s (formerly MicroStrategy) variable Rate Series A Perpetual Stretch Preferred Stock.
It is priced at a $100 stated value and the issuer adjusts the monthly dividend to keep the price hovering near $100. The annualised rate is 11.5%, paid in cash, a strikingly high dollar yield.
The tax feature is what puts it on this list. Strategy reports that it has no accumulated or current earnings & profits for US tax purposes, and does not expect to for the foreseeable future.
As a result, 100% of 2025 STRC distributions were treated as a non taxable return of capital (ROC) rather than dividend income.
ROC is treated as getting your own money back: it is not taxed as income, it simply reduces your cost basis, and only once basis hits zero does any excess become a capital gain.
Stacking the two jurisdictions for a returning NRI:
In the US: to the extent distributions are return of capital, there is no US income tax on them, and for a non resident alien, ROC is not US source dividend income subject to the 30% withholding that normally applies to dividends.
In India: during your NRI and RNOR years, foreign dividends (and foreign capital gains) are outside the Indian tax net so long as they are not received in or controlled from India. So the same income India would tax for an ordinary resident stays exempt while you are RNOR.
STRC is NOT a defensive, capital protected instrument Be clear-eyed: STRC is preferred equity of a company whose balance sheet is concentrated in Bitcoin. The 11.5% yield is high precisely because the risk is real. It depends on Strategy’s solvency and is exposed, indirectly, to Bitcoin’s volatility. The price targets ~$100 but is not guaranteed to hold it, dividends are variable and can be changed, and the ROC treatment lasts only while the company has no earnings & profits (if that changes, distributions could become taxable dividends). Treat STRC as a high yield, high risk satellite holding (never as the safe ballast of your portfolio). |
4. Two more clean options: US Treasuries and municipal bonds
US Treasuries (or T-bill ETFs like SGOV, BIL)
The genuinely risk free benchmark. Backed by the US government, currently yielding roughly 3.7% (short bills) to 4.5% (10-year). For a non resident alien, interest on US Treasuries is exempt from US tax under the portfolio interest rules (file a Form W-8BEN), and it is foreign income that India does not tax during your NRI/RNOR years.
The catch versus BOXX: Treasury interest is taxable to a US person, so the full “tax-free both sides” benefit only applies once you have become an NRA. Fully liquid, unlike FCNR.
US municipal bonds (or muni bond ETFs)
Municipal bond interest is exempt from US federal income tax for everyone (US persons and non resident aliens alike)
This is foreign income exempt in India during RNOR. That makes munis a clean “tax free in both countries” defensive holding even before you change residency.
The trade offs: yields are lower than Treasuries (because of the tax break), and you take interest rate and some credit risk. A simple national muni ETF spreads that risk.
Reyman Tip: BOXX, STRC, US Treasuries and muni bonds are all US situs assets which can expose a non-resident alien to US estate tax above just $60,000 on death. Plan the holding structure before you build large positions. See How to Plan for US Estate Taxes for Returning Indians.
