US Tax Filing for Non-Residents: Form 1040-NR, IRS Compliance — Complete Guide

The United States is unusual among major economies in that it taxes non-residents on their U.S.-source income — regardless of where those individuals or companies are based. If you are a French resident, an international entrepreneur, or a foreign company with U.S. investments, you may have IRS filing obligations that you are unaware of.

This applies to:

• French and European investors earning dividends from U.S. stocks
• Non-residents who own rental properties in the United States
• Foreign professionals receiving fees or compensation from U.S. companies
• Foreign partners in U.S. partnerships or LLCs
• Anyone who sold U.S. real estate (FIRPTA)

This comprehensive guide by Hayot-expertise.fr — specialists in French-American cross-border taxation — explains who must file, which forms to use, how the France-US tax treaty protects you, and how to recover taxes that were withheld in excess.

The Two-Test Framework#

For U.S. federal income tax purposes, you are a Non-Resident Alien (NRA) if you do not satisfy either of the following:

Test 1 — Green Card Test: You hold a U.S. Permanent Resident Card (Green Card). If you do, you are taxed as a U.S. resident on your worldwide income.

Test 2 — Substantial Presence Test: You are considered a U.S. resident for tax purposes if you were physically present in the U.S. for:

• At least 31 days during the current calendar year, AND
• At least 183 days over the current year and the two preceding years, using the weighted formula: 100% of current year days + 33% of prior year days + 16.7% of the year before that

If you fail both tests, you are a Non-Resident Alien and are subject to U.S. tax only on your U.S.-source income — not your worldwide income.

Common situation: A French resident who visits the U.S. for 2 weeks per year and owns U.S. shares and a Florida condo is almost certainly a Non-Resident Alien. They are subject to U.S. tax on U.S. dividends and U.S. rental income, but not on their French salary or French investment income.

Income Overview by Category#

Effectively Connected Income (ECI) vs. Fixed/Determinable/Annual/Periodical (FDAP)#

U.S. tax law distinguishes two categories of NRA income:

• FDAP income (dividends, rents, royalties, interest): generally subject to flat 30% withholding at source (or reduced treaty rate). No deductions allowed — taxed on gross amount
• ECI income (actively connected business income): taxed at the same progressive rates as U.S. residents (10%–37%), but deductions are allowed — taxed on net income

This distinction is critical: if you own U.S. rental property and elect to treat it as a business (Section 871(d) election), your rental income becomes ECI — meaning you can deduct mortgage interest, property taxes, depreciation, and management fees before calculating tax. The savings can be substantial.

The Convention Between the United States of America and the French Republic for the Avoidance of Double Taxation (signed 1994, amended 2009) is one of the most comprehensive bilateral tax treaties in existence. It protects French residents from being double-taxed on their U.S.-source income.

Key provisions:

To benefit from treaty rates, you must certify your French residency to your U.S. payer (typically via Form W-8BEN). If your payer withheld at the standard 30% rate despite your French residency, you are entitled to a refund — claimed via Form 1040-NR.

What Is Form 1040-NR?#

The Form 1040-NR (U.S. Nonresident Alien Income Tax Return) is the U.S. federal tax return for non-residents. It is the equivalent of the regular Form 1040 used by U.S. residents and citizens, adapted for non-residents taxable only on U.S.-source income.

Filing a 1040-NR allows you to:

• Declare your U.S.-source income by category
• Claim treaty rate reductions (e.g., reduce withholding from 30% to 15%)
• Elect net income taxation for rental income (avoiding the default 30% gross withholding)
• Claim deductions on ECI income (mortgage interest, depreciation, professional expenses)
• Recover excess withholding if your payer withheld more than you actually owe
• Obtain an IRS refund where applicable

Key Sections of Form 1040-NR#

Page 1 — Identification and filing status: Your name, address, ITIN or SSN, country of residence, and foreign tax identification number.

Schedule NEC (Non-ECI Income): This is where you report FDAP income (dividends, rents subject to gross withholding) and claim treaty rate reductions. Each income item is reported alongside the applicable treaty article.

Schedule 1 (ECI Income): Business income, rental income under the net election, and other effectively connected income. Standard deductions apply.

Tax credits: You can claim a Foreign Tax Credit for French taxes paid on income also taxed by France, avoiding double taxation.

Who Needs an ITIN to File?#

To file a 1040-NR, you need a U.S. tax identification number. If you are not eligible for a Social Security Number (SSN), you need an ITIN (Individual Taxpayer Identification Number). This is a 9-digit number issued by the IRS specifically to non-residents with U.S. tax obligations. See our separate guide on obtaining an ITIN.

FBAR (Foreign Bank Account Report — FinCEN Form 114)#

The FBAR applies to US persons (citizens, Green Card holders, or those who pass the Substantial Presence Test) with foreign bank accounts that collectively exceeded $10,000 at any point during the year. Penalties for non-filing can reach $10,000 per account per year for non-willful violations, and up to $100,000 per account for willful violations.

For true Non-Resident Aliens, the FBAR generally does not apply. However, if your residency status is uncertain — for example, if you have spent significant time in the U.S. — a careful analysis is essential before concluding you are exempt.

FATCA (Foreign Account Tax Compliance Act)#

FATCA requires foreign financial institutions (including French banks) to report to the IRS accounts held by U.S. persons. If you hold U.S. citizenship or have previously resided in the U.S., your French bank may ask you to complete a Form W-9 to certify your U.S. person status. This is a FATCA compliance procedure.

FIRPTA: Withholding on U.S. Real Estate Sales#

When a non-resident sells U.S. real estate, the buyer is legally required to withhold 15% of the gross sale price and remit it to the IRS (Foreign Investment in Real Property Tax Act — FIRPTA). This is a withholding mechanism, not a final tax.

You then file a 1040-NR to calculate your actual capital gains tax on the net profit. If the 15% withholding exceeds your actual tax, you receive the difference as a refund. FIRPTA withholding can be reduced or eliminated through an IRS withholding certificate if you can demonstrate the actual tax will be lower.

Important: NRAs living outside the U.S. automatically receive a 2-month extension (April 15 → June 15) without needing to request it. However, if you owe tax, interest accrues from April 15 — so paying early reduces your interest cost even if you file later.

Late penalties:

• Late filing: 5% of unpaid tax per month (maximum 25%)
• Late payment: 0.5% per month (maximum 25%)
• Missed FBAR (non-willful): up to $10,000 per account
• Missed FBAR (willful): up to $100,000 or 50% of account balance

Case Study 1: French Investor Recovering Excess U.S. Dividend Withholding#

Situation: Sophie, a French tax resident, holds a $200,000 U.S. stock portfolio (Apple, Microsoft, Coca-Cola) generating $6,000 in annual dividends. Her French broker applies 30% U.S. withholding by default.

Problem: The France-USA treaty caps withholding at 15%. At 30%, she is overpaying: $1,800 withheld vs. $900 owed. The $900 excess is refundable by the IRS.

Solution:

1. Obtain an ITIN (since she has no SSN)
2. File Form 1040-NR claiming the 15% treaty rate on dividends
3. IRS issues a refund of $900
4. For future years: submit Form W-8BEN to the U.S. payer to enforce treaty rate at source

Lesson: Filing a 1040-NR is not only a compliance requirement — it is often a tax recovery tool.

Case Study 2: Non-Resident Owner of a Miami Rental Property — Net Income Election#

Situation: Pierre, based in Lyon, owns a Miami condominium rented long-term for $24,000 gross annual rent. His actual expenses (mortgage interest, HOA fees, property management, property tax, depreciation) total $18,000.

Option A — Default 30% gross withholding (no 1040-NR): $24,000 × 30% = $7,200 U.S. tax

Option B — Net income election + 1040-NR: ($24,000 – $18,000) × 10% progressive rate = $600 U.S. tax

Annual tax saved by filing Form 1040-NR: $6,600

This election under IRC Section 871(d) must be made by filing a 1040-NR. It cannot be claimed retroactively beyond the standard 3-year refund window.

1. Determine your NRA status — confirm you fail both the Green Card Test and the Substantial Presence Test
2. Obtain an ITIN (Form W-7) if you lack a Social Security Number
3. Collect U.S. source documents: Form 1042-S (withholding statements), rental income records, sale/closing statements, Schedule K-1 from any U.S. partnership
4. Elect net income treatment for rental income if advantageous (Section 871(d))
5. Prepare and file Form 1040-NR with all applicable schedules and treaty claims
6. Submit Form W-8BEN to your U.S. payers to enforce treaty rates going forward
7. Verify FBAR and FATCA obligations if your residency status is at all ambiguous
