Cross-Border Tax Planning
US-India Strategies

Why Cross-Border Tax Planning Matters

NRIs and Indian nationals working in the US face a unique challenge: two countries, two tax systems, and a web of rules that interact in complex ways. Without proactive planning, you can end up paying significantly more tax than required— or worse, face penalties for non-compliance with reporting requirements you didn't know existed.

Cross-border tax planning is not just about filing returns correctly. It's about making strategic decisions throughout the year — when to exercise stock options, how much to contribute to retirement accounts, whether to use the Foreign Tax Credit or FEIE, and how to structure your finances before a major life event like returning to India.

This guide covers the key planning areas where informed decisions make the biggest difference. For filing mechanics and compliance requirements, see our companion guide: NRI US Tax Filing Complete Guide.

RSU & ESOP Taxation

Stock compensation is the single largest source of tax complexity for NRIs in tech and finance. Understanding how RSUs and stock options are taxed — especially across borders — is critical.

RSUs (Restricted Stock Units)

RSUs are taxed in two events:

1. At vesting — the fair market value (FMV) of the shares on the vesting date is reported as ordinary income on your W-2. Your employer withholds income tax, Social Security, and Medicare.
2. At sale — the difference between the sale price and the FMV at vesting is a capital gain or loss. If held more than one year after vesting, it qualifies for long-term capital gains rates (0/15/20%).

Stock Options (ISO vs NQSO)

Non-Qualified Stock Options (NQSOs) are taxed as ordinary income at exercise (spread between exercise price and FMV). Incentive Stock Options (ISOs) have no regular tax at exercise, but the spread is an AMT preference item — meaning you may owe Alternative Minimum Tax. ISOs get favorable long-term capital gains treatment if you hold the shares for at least 1 year after exercise and 2 years after grant.

Cross-Border RSU Allocation

If you move between the US and India during a vesting period, the RSU income is allocated between the two countries based on the number of days worked in each during the vesting period. For example, if your RSU has a 4-year vesting schedule and you spend 3 years in the US and 1 year in India, approximately 75% of the vesting income is US-source and 25% is India-source. Both countries will want to tax their portion, and you claim a Foreign Tax Credit to avoid double taxation.

Retirement Accounts: 401(k) & IRA

US retirement accounts are one of the most powerful tax planning tools available to NRIs. However, the cross-border implications require careful consideration, especially if you plan to return to India.

401(k) Contributions

For 2025, you can contribute up to $23,500 ($31,000 if age 50+) to a Traditional 401(k), reducing your taxable income dollar-for-dollar. Employer matches are free money — always contribute at least enough to capture the full match. NRIs on H-1B, L-1, and other work visas are fully eligible to participate.

Traditional vs Roth 401(k)

IRA Options

Individual Retirement Accounts offer additional tax-advantaged savings. For 2025, you can contribute up to $7,000 ($8,000 if 50+). Traditional IRA contributions may be tax-deductible depending on your income and whether you have a workplace plan. Roth IRA contributions are not deductible but offer tax-free growth and withdrawals.

What Happens When You Leave the US?

Your 401(k) and IRA remain intact — you do not have to cash them out. Options include leaving the 401(k) with your employer, rolling it to an IRA, or taking a distribution (subject to tax and potential penalties). Under DTAA Article 20, pension distributions to an India-resident are generally taxable only in India, with credit for any US withholding.

See our detailed guides: 401(k) & IRA Guide for NRIs and Roth IRA for NRIs.

Roth IRA: Strategic Considerations

The Roth IRA is uniquely attractive — and uniquely complicated — for NRIs. Tax-free growth and withdrawals in the US make it a powerful wealth-building tool, but the cross-border implications require careful strategy.

Eligibility & Income Limits (2025)

Direct Roth IRA contributions phase out between $150,000-$165,000 (single) and $236,000-$246,000 (married filing jointly). If your income exceeds these limits, you can use the backdoor Roth strategy: contribute to a non-deductible Traditional IRA, then immediately convert it to a Roth. This is legal and widely used, though the pro-rata rule applies if you have existing pre-tax IRA balances.

The India DTAA Problem

Planning strategies:

• If staying in the US long-term: Maximize Roth contributions. Tax-free compounding over decades is extremely powerful.
• If returning to India within 5-10 years: Consider withdrawing or converting to Traditional IRA before becoming an India resident. Alternatively, keep the Roth but invest in growth stocks (no dividends) to minimize annual taxable events in India.
• Roth conversion ladder: If you have a low-income year (sabbatical, between jobs), convert Traditional IRA/401(k) balances to Roth at a low tax rate. Each conversion starts a new 5-year clock for penalty-free withdrawal.

Foreign Earned Income Exclusion (FEIE)

The FEIE allows US citizens and resident aliens with a tax home in a foreign country to exclude up to $130,000 (2025) of foreign earned income from US taxation. It is claimed on Form 2555.

Qualifying Tests

You must meet one of two tests:

1. Bona Fide Residence Test — you must be a bona fide resident of a foreign country for an uninterrupted period that includes a full tax year. Short trips back to the US don't break this, but you must demonstrate genuine residence (housing, family, community ties).
2. Physical Presence Test — you must be physically present in a foreign country for at least 330 full days during any 12-month period. Days spent in transit over international waters count, but days in the US do not.

FEIE vs Foreign Tax Credit: Which Is Better?

You cannot use both FEIE and FTC on the same income. The choice depends on the tax rate of the country you live in:

For full details, read Foreign Earned Income Exclusion (FEIE) Guide.

Foreign Tax Credit (Form 1116)

The Foreign Tax Credit is the primary mechanism the US provides to prevent double taxation. For most NRIs with Indian income, the FTC is more beneficial than the FEIE.

How It Works

You claim a dollar-for-dollar credit on your US return for income taxes paid to a foreign country. The credit is limited to the US tax attributable to foreign-source income — you cannot use foreign taxes to offset US tax on US-source income. The FTC is calculated separately for each category of income: general, passive, and certain others.

Common FTC Scenarios for NRIs

• Indian rental income — TDS deducted by your tenant (or advance tax paid) is creditable via Form 1116.
• NRO account interest — Indian TDS on NRO interest (typically 30%) can be credited against US tax on the same interest.
• Indian capital gains — Short-term and long-term capital gains tax paid in India is creditable, though the FTC limitation may cap the credit if Indian rates exceed US rates on that income.
• Salary taxed in both countries — If RSU or employment income is allocated between US and India, taxes paid to India on the Indian portion are creditable.

Carryover Rules

If your foreign taxes paid exceed the FTC limitation in a given year, the excess can be carried back 1 year or carried forward up to 10 years. This is common for NRIs in high-tax situations (e.g., Indian short-term capital gains taxed at 15% in India when the US rate on the same income might be lower after deductions).

Dual-Status Filing

If you change your tax residency status during the year — arriving in the US on an H-1B mid-year or departing permanently — you may need to file as a dual-status alien.

How It Works

In a dual-status year, you are taxed as a non-resident alien for the part of the year before your residency start date (US-source income only), and as a resident alien for the remainder (worldwide income). You file Form 1040 for the full year and attach a statement showing the Form 1040-NR computation for the non-resident period.

Key Limitations

• You cannot claim the standard deduction in a dual-status year.
• You cannot file jointly with your spouse (unless you make the first-year choice election).
• You cannot claim the Earned Income Tax Credit.

First-Year Choice Election (IRC 6013(g))

If you are married to a US citizen or resident alien, you can elect to be treated as a resident alien for the entire year. This allows joint filing and the standard deduction, but it also means your worldwide income for the full year is taxable in the US. This election is beneficial if the tax savings from joint filing and the standard deduction outweigh the tax on additional worldwide income.

Returning to India: Tax Exit Planning

The year you leave the US permanently is one of the most tax-sensitive events in an NRI's financial life. Proper exit planning can save tens of thousands of dollars.

Pre-Departure Checklist

Ongoing US Obligations After Departure

Your US tax filing obligation depends on your status:

• Green Card holders: You remain a US tax resident until you formally abandon your Green Card (Form I-407) or it expires. You must continue filing US returns on worldwide income.
• H-1B / L-1 visa holders: Once you leave the US and fail the Substantial Presence Test, you become a non-resident alien. You only file on US-source income (if any) going forward.
• FBAR: Filing obligation continues as long as you are a US person with foreign accounts above $10,000. H-1B holders who depart are no longer US persons; Green Card holders still are until abandonment.
