For nonresidents, the difference between active vs. passive income tax in the United States comes down to two very different regimes: money you earn from working or running a business here is taxed at the same graduated rates U.S. citizens pay, while investment income from U.S. sources is generally hit with a flat 30% tax on the gross amount, with no deductions. Getting the classification right can save you thousands of dollars, and for visa holders, it can also keep you out of immigration trouble.
What Counts as Active Income
The IRS calls active earnings “effectively connected income,” or ECI. Income qualifies as ECI when it is connected with carrying on a trade or business inside the United States.1Office of the Law Revision Counsel. 26 U.S.C. 864 – Definitions and Special Rules That covers wages, self-employment profits, and business revenue. What matters is where you perform the work, not where your employer sits or where the paycheck lands. A nonresident performing services on U.S. soil for a foreign company still generates ECI.
Real estate is where classifications shift most often. Passively collecting rent through a management company looks like investment income. Once you start making management decisions, negotiating leases, or directing repairs yourself, the IRS views you as running a business, and the rental income converts to ECI.2Internal Revenue Service. Income From Sources Within the US and ECI
One useful safe harbor: if your only U.S. business activity is trading stocks, securities, or commodities through a U.S.-based broker, the IRS does not treat you as engaged in a U.S. trade or business. Your trading profits stay outside ECI regardless of volume.3Internal Revenue Service. Effectively Connected Income (ECI)
What Counts as Passive Income
Passive U.S.-source income falls under a category the tax code calls “fixed, determinable, annual, or periodical” income, shortened to FDAP. Dividends, interest, rent, royalties, annuities, and similar recurring payments from U.S. sources all sit here.4Office of the Law Revision Counsel. 26 U.S.C. 1441 – Withholding of Tax on Nonresident Aliens The defining feature is that the money comes to you as a return on capital, not from personal effort.
Bank deposit interest technically fits the FDAP framework but is generally exempt from tax for nonresidents. The other common examples include dividends from U.S. corporations, royalties on intellectual property used in the U.S., and annuity payments.
The Rate Difference and What You Can Deduct
ECI is taxed at the same graduated rates that apply to U.S. citizens and residents.5Office of the Law Revision Counsel. 26 U.S.C. 871 – Tax on Nonresident Alien Individuals For the 2026 tax year, single filers face these brackets:6Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- 10% on income up to $12,400
- 12% from $12,401 to $50,400
- 22% from $50,401 to $105,700
- 24% from $105,701 to $201,775
- 32% from $201,776 to $256,225
- 35% from $256,226 to $640,600
- 37% on income over $640,600
Nonresidents can claim itemized deductions against ECI, including state and local income taxes, charitable contributions to U.S.-based organizations, and business expenses.7eCFR. 26 CFR 1.873-1 – Deductions Allowed Nonresident Alien Individuals But you generally cannot claim the standard deduction; you have to itemize.8Internal Revenue Service. Nonresident – Figuring Your Tax A narrow exception exists for students and business apprentices from India under the U.S.-India tax treaty.
Timing carries a hard edge. If you fail to file a return within 16 months of the original due date, the IRS can deny all your deductions and credits, leaving you taxed on gross income with no offsets.9Internal Revenue Service. Taxation of Nonresident Aliens
FDAP is taxed at a flat 30% of the gross amount, with no deductions.10Office of the Law Revision Counsel. 26 U.S.C. 871 – Tax on Nonresident Alien Individuals If you receive $10,000 in U.S.-source dividends, the tax is $3,000, full stop. You cannot subtract expenses or management fees. The payer or withholding agent usually deducts the 30% before the money reaches you, so collection happens at the source.
The Section 871(d) Election on Rental Property
Nonresidents who own U.S. rental property face the single biggest planning choice in this area. By default, rent from a purely passive investment is FDAP, taxed at 30% on gross rent. The tax code lets you elect to treat that rental income as ECI instead.11Office of the Law Revision Counsel. 26 U.S. Code 871 – Tax on Nonresident Alien Individuals
The math usually favors the election. Say you collect $50,000 in annual rent but carry $35,000 in mortgage interest, property taxes, depreciation, and maintenance. Under the default, you owe 30% of $50,000, or $15,000. With the election, you pay graduated rates on the $15,000 net profit, and the tax bill drops under $2,000.
The election stays in effect for all future years unless you get IRS permission to revoke it. If you do revoke, you cannot make the election again for at least five years.11Office of the Law Revision Counsel. 26 U.S. Code 871 – Tax on Nonresident Alien Individuals You make the election by filing Form 1040-NR and reporting the rental income as ECI with the associated deductions.12Internal Revenue Service. Nonresident Aliens – Real Property Located in the U.S. The same 16-month filing window applies.
Treaty Rates and the Portfolio Interest Exemption
Tax treaties between the U.S. and other countries often cut the 30% FDAP rate substantially. A treaty might reduce withholding on dividends to 15%, lower the tax on royalties, or eliminate the tax on interest entirely. To claim the reduced rate, you provide your withholding agent with Form W-8BEN before payment is made.13Internal Revenue Service. About Form W-8 BEN The form certifies your foreign status and identifies the treaty provision you are relying on.14Internal Revenue Service. Form W-8BEN – Certificate of Foreign Status Without it, the payer withholds the full 30%.
The portfolio interest exemption goes further, letting nonresidents receive certain interest payments completely tax-free. The debt has to be in registered form, and you must give the payer a Form W-8BEN certifying you are not a U.S. person. Several things disqualify you: owning 10% or more of the voting power of the corporation paying the interest, owning 10% or more of a partnership’s capital or profits, contingent interest that depends on the debtor’s profits or property values, and bank loans made in the ordinary course of the bank’s lending business.15Internal Revenue Service. Portfolio Debt Exemption – Requirements and Exceptions
Selling U.S. Real Estate: FIRPTA
Selling U.S. real estate as a nonresident triggers a separate withholding regime that catches many foreign sellers off guard. Under FIRPTA, the buyer must withhold 15% of the total sale price and send it to the IRS at closing.16Office of the Law Revision Counsel. 26 U.S.C. 1445 – Withholding of Tax on Dispositions of United States Real Property Interests Note that this is 15% of the gross sale price, not 15% of your profit, so the withholding can easily exceed your actual tax bill.
A reduced rate of 10% applies when the buyer plans to use the property as a personal residence and the sale price is $1,000,000 or less.16Office of the Law Revision Counsel. 26 U.S.C. 1445 – Withholding of Tax on Dispositions of United States Real Property Interests If the sale price is $300,000 or less and the buyer will use it as a residence, withholding may be waived entirely. You can also apply for an IRS withholding certificate to reduce the amount withheld to your estimated actual tax, but the application has to be filed before closing to be useful. Any overwithholding is refundable when you file your return, but the cash is tied up until then.
Where Tax Classification Becomes a Visa Problem
The tax classification of your income and its immigration consequences are separate questions that overlap in ways that can hurt. Federal regulations require that nonimmigrants may only work if their visa classification specifically authorizes employment, or if they have received separate permission. Unauthorized employment is a failure to maintain status and can lead to removal.17eCFR. 8 CFR 214.1 – Requirements for Admission, Extension, and Maintenance of Status
Passive investment income is not employment. You can receive dividends, interest, or hands-off rent on any visa status without needing work authorization. USCIS treats these as returns on capital. The problem starts when a passive investment turns active.
Consider an F-1 student who owns a U.S. rental property. Collecting rent through a property manager is fine. If the same student begins interviewing tenants, coordinating repairs, and negotiating leases, those activities look like employment. Whether you pay yourself is not the test. Immigration law focuses on the activity itself, not on compensation. Managing operations, hiring workers, and directing employees can each amount to unauthorized work regardless of whether money changes hands.
Owning shares in a U.S. company is also different from working for it. A B-1 visitor can enter to secure funding, negotiate contracts, or attend business meetings related to opening a venture, but cannot actually operate it or work for it once it exists.18U.S. Citizenship and Immigration Services. Options for Alien Entrepreneurs to Work in the United States The line between ownership and hands-on work varies by visa category, and crossing it can lead to denial of future applications.
FICA Exemption for Student Visa Holders
Nonresident aliens on F-1, J-1, or M-1 student visas who have been in the U.S. for fewer than five calendar years are generally exempt from Social Security and Medicare taxes on their wages. The work must be authorized by USCIS and connected to the purpose of the visa, such as on-campus employment, approved off-campus work, or practical training.19Internal Revenue Service. Foreign Student Liability for Social Security and Medicare Taxes
The exemption does not extend to dependents on F-2, J-2, or M-2 visas. It also ends if you switch to a status that does not qualify, or if you become a resident alien by meeting the substantial presence test. A separate exemption covers any student employed by the school where they are enrolled at least half-time, regardless of citizenship, but only for work at that specific institution.19Internal Revenue Service. Foreign Student Liability for Social Security and Medicare Taxes
If your employer mistakenly withholds these taxes when you qualify for the exemption, ask the employer to correct it first. If the employer will not or cannot adjust the overcollection, you can file Form 843 with the IRS to claim a refund. You need a copy of your W-2 and a statement from the employer explaining whether any reimbursement was already made.20Internal Revenue Service. Instructions for Form 843
Filing: Forms, Deadlines, and IDs
Nonresidents report U.S.-source income on Form 1040-NR. ECI goes on the main body of the form with any applicable deductions. FDAP income that is not connected to a U.S. business goes on Schedule NEC, which calculates the flat 30% tax or reduced treaty rate on each type of passive income.21Internal Revenue Service. Instructions for Form 1040-NR
If you received wages with U.S. income tax withheld, your return is due April 15 following the close of the tax year. If you did not receive wages subject to withholding and have no U.S. office or place of business, the deadline extends to June 15.9Internal Revenue Service. Taxation of Nonresident Aliens21Internal Revenue Service. Instructions for Form 1040-NR Missing those dates triggers a failure-to-file penalty of 5% of the unpaid tax per month, capped at 25%.22Internal Revenue Service. Failure to File Penalty The IRS waives it only for reasonable cause.
Filing federally may not be the end of it. Most states that levy an income tax also require nonresidents to file a state return if they earned income within the state’s borders. Rules vary widely: some states require a return after even a single day of work, others use day or income thresholds, and nine states have no individual income tax on wages at all. Income in multiple states can mean returns in each one.
If you are not eligible for a Social Security number but need to file or claim treaty benefits, you must apply for an Individual Taxpayer Identification Number using Form W-7. A current passport is the simplest path because it is the only document that can stand alone. Without a passport, you need at least two forms of identification from the IRS’s list of acceptable documents. The application is submitted with your tax return or when you need the ITIN to claim a treaty exemption.23Internal Revenue Service. Instructions for Form W-7
Confirm You Are Actually a Nonresident First
None of this applies unless you are actually a nonresident alien for tax purposes. The IRS treats you as a nonresident if you are not a U.S. citizen and you fail both the green card test and the substantial presence test.24Office of the Law Revision Counsel. 26 U.S.C. 7701 – Definitions The green card test is simple: if you are a lawful permanent resident at any point during the year, you are a resident for tax purposes. The substantial presence test counts your days in the U.S. across a three-year period using a weighted formula. Meet either, and you are taxed as a resident, and the ECI/FDAP split does not shape your return.
Certain visa holders are exempt from the substantial presence test for a period. F-1 and J-1 students generally do not count their first five calendar years of U.S. presence toward it, which keeps them in nonresident status longer and affects both their income tax treatment and their FICA obligations. If your status is unclear, sort the residency question first, because every other rule here depends on the answer.
