What Is FDAP Income and How Is It Taxed?
FDAP stands for Fixed, Determinable, Annual, or Periodical income. It is the IRS category for U.S.-source passive income paid to nonresident aliens and other foreign persons. FDAP income is taxed at a flat 30% rate on the gross amount, with no deductions allowed, unless a tax treaty reduces the rate.
According to the IRS, common types of FDAP income include interest, dividends, rents, royalties, compensation for personal services, annuities, and certain pension payments from U.S. sources.
Understanding FDAP matters because the tax is withheld at the source before you receive the payment. If you’re a nonresident alien earning any type of U.S.-source income, or a U.S. business paying a foreign person, the FDAP rules determine how much is withheld and whether you can reduce that amount.
Not Sure If Your Income Is FDAP?
Here’s how FDAP income works, what it includes, how it differs from effectively connected income (ECI), and how tax treaties can lower your rate.
How Is FDAP Income Taxed?
FDAP income is taxed differently from the income of U.S. citizens and residents. The key differences:
| Feature | FDAP Income | Effectively Connected Income (ECI) |
|---|---|---|
| Tax rate | Flat 30% (or lower treaty rate) | Graduated rates (10% to 37%) |
| Taxed on | Gross income (no deductions) | Net income (deductions allowed) |
| Who it applies to | Nonresident aliens with U.S.-source passive income | Nonresident aliens with U.S. trade or business income |
| Withholding | Withheld at source by the payer | May be withheld; reported on Form 1040-NR |
| Reported on | Schedule NEC (Form 1040-NR) | Page 1 of Form 1040-NR |
| Can claim standard deduction? | No | Limited (generally no, but certain itemized deductions allowed) |
The 30% rate applies to the gross amount. This means if you receive $10,000 in U.S. dividends as a nonresident alien, the withholding agent deducts $3,000 and sends it to the IRS. You receive $7,000. You cannot deduct any expenses against this income to reduce the amount subject to tax.
The same income can potentially be classified as either FDAP or ECI depending on whether it’s connected to a U.S. trade or business. The classification matters enormously because ECI allows deductions and is taxed at graduated rates, while FDAP is taxed on the full gross amount at a flat rate.
What Types of Income Qualify as FDAP?
FDAP is a broad category. The IRS defines it as income that is “fixed” (paid in known amounts), “determinable” (there is a basis for calculating the amount), “annual” or “periodical” (paid from time to time, though it doesn’t have to be regular). It can be paid in a series of payments or as a lump sum.
Common FDAP Income Types
| Income Type | Example | Notes |
|---|---|---|
| Dividends | Dividends from U.S. corporations | One of the most common FDAP categories |
| Interest | Interest from U.S. bank accounts, bonds, or notes | Portfolio interest on registered bonds may be exempt |
| Rent | Rental income from U.S. real estate | Can elect to treat as ECI instead (see below) |
| Royalties | Payments for use of U.S. intellectual property, copyrights, patents | Common for foreign licensors |
| Compensation | Fees for personal services performed in the U.S. | If not connected to a U.S. trade or business |
| Pensions and annuities | U.S. pension distributions, annuity payments | Treaty rates often apply |
| Social Security | U.S. Social Security benefits | 85% of the benefit is FDAP; some treaties exempt this |
| Scholarships and fellowships | Amounts paid to NRA students beyond tuition | Tuition payments are generally exempt |
| Insurance proceeds | Life insurance proceeds above policy cost | Specific rules apply |
| Partnership distributions | FDAP income distributed from a U.S. partnership to a foreign partner | Withholding required |
| Estate/trust distributions | FDAP income distributed to NRA beneficiaries | Withholding required |
What Is NOT FDAP Income?
Certain types of income are specifically excluded from FDAP treatment:
- Capital gains of nonresident aliens present in the U.S. for fewer than 183 days (generally not taxable)
- Portfolio interest on registered obligations (exempt from withholding under IRC 871(h))
- Bank deposit interest from U.S. banks (generally exempt for NRAs)
- Gains from the sale of U.S. real property (taxed under FIRPTA rules as ECI, not FDAP)
- Income effectively connected with a U.S. trade or business (taxed as ECI at graduated rates)
FDAP vs. ECI: Why the Distinction Matters
The distinction between FDAP and effectively connected income (ECI) is among the most consequential in international tax. Getting it wrong can mean overpaying by thousands of dollars or facing compliance penalties.
When FDAP Classification Costs You More
Scenario: You’re a nonresident alien who earns $50,000 in U.S. rental income and has $20,000 in deductible expenses (mortgage interest, property taxes, repairs, depreciation).
If treated as FDAP:
- Tax = 30% of $50,000 gross = $15,000
- No deductions allowed
If you elect ECI treatment (Net Income Election):
- Taxable income = $50,000 minus $20,000 expenses = $30,000
- Tax at graduated rates = approximately $3,400
- Savings: $11,600
This is why the Net Income Election under IRC Section 871(d) is so important for nonresident aliens with U.S. rental property. By electing to treat rental income as ECI, you can deduct expenses and pay tax on net income at graduated rates instead of 30% on gross rent.

How Tax Treaties Reduce FDAP Rates
The 30% flat rate is the default, but the United States has income tax treaties with more than 60 countries that can reduce or eliminate withholding on specific types of FDAP income. Treaty rates vary by country and by income type.
Common Treaty Rate Reductions
| Income Type | Default Rate | Common Treaty Rates |
|---|---|---|
| Dividends | 30% | 15% (most treaties); 5% for substantial shareholders; 0% (some treaties) |
| Interest | 30% | 0-15% (varies widely by treaty) |
| Royalties | 30% | 0-10% (many treaties reduce to 0%) |
| Pensions | 30% | 0-15% (some treaties exempt entirely) |
| Social Security | 30% (on 85%) | 0% (exempt under many treaties, including Canada, UK, Germany) |
How to Claim a Treaty Rate
To claim a reduced rate, you must provide the U.S. payer (the withholding agent) with a completed Form W-8BEN before the payment is made. This form certifies that you are a foreign person and identifies the treaty country and article you’re claiming.
Without a valid W-8BEN on file, the payer must withhold at the full 30% rate. Recovering overwithheld amounts after the fact requires filing Form 1040-NR and claiming a refund, which can take months.
W-8BEN forms expire after three calendar years. If your form expires and you don’t submit a new one, the withholding agent must revert to the 30% default rate on your next payment. Set a reminder to renew.
How FDAP Withholding Works
The U.S. payer (called the “withholding agent”) is legally responsible for withholding the correct amount of tax from FDAP payments to foreign persons and remitting it to the IRS.
The Withholding Process
- Foreign person provides Form W-8BEN (or W-8BEN-E for entities) to the payer
- Payer determines the correct withholding rate (30% or treaty rate)
- Payer withholds tax from the gross payment at the time of payment
- Payer remits withheld tax to the IRS using Form 1042
- Payer reports the payment and withholding on Form 1042-S, which is sent to the foreign person
The withholding agent faces liability if they fail to withhold correctly. If no W-8 form is on file, the payer must withhold at 30% regardless of any applicable treaty.
Reporting FDAP on Your Tax Return
If you’re a nonresident alien who received FDAP income, you report it on Schedule NEC (Tax on Income Not Effectively Connected With a U.S. Trade or Business), which is part of Form 1040-NR.
If tax was overwithheld (for example, the payer withheld 30% but a treaty entitles you to 15%), you can claim a refund by filing Form 1040-NR and attaching the Form 1042-S you received from the payer.
Special FDAP Rules for Expats and Dual-Status Filers
U.S. Citizens and Residents: FDAP Doesn’t Apply to You
If you are a U.S. citizen or resident alien (including Green Card holders), the FDAP rules do not apply to your income. You are taxed on worldwide income at graduated rates, and you can claim deductions and credits. FDAP withholding is a concept for nonresident aliens.
However, FDAP becomes relevant if:
- You’re transitioning residency status. During a dual-status year (the year you move to or from the U.S.), income earned during your nonresident period may be subject to FDAP treatment.
- You’re a U.S. business paying foreign contractors or investors. You may be the withholding agent responsible for withholding on FDAP payments to foreign persons.
- You’ve renounced citizenship or abandoned your Green Card. After expatriation, your U.S.-source income shifts to FDAP/ECI treatment.
The Net Income Election for Rental Property
Nonresident aliens who own U.S. rental property should strongly consider the Net Income Election under IRC 871(d). Without this election, rental income is FDAP, taxed at 30% on gross rent with no deductions. With the election, rental income is treated as ECI, allowing you to deduct expenses and depreciation and pay tax at graduated rates on net income.
The election is made by attaching a statement to your Form 1040-NR. Once made, it applies to all future years unless the IRS approves revocation.
Frequently Asked Questions
FDAP stands for Fixed, Determinable, Annual, or Periodical income. It’s the IRS category for U.S.-source passive income paid to nonresident aliens and other foreign persons, typically taxed at a flat 30% rate on the gross amount.
No. FDAP is a nonresident alien tax concept. U.S. citizens and resident aliens are taxed on worldwide income at graduated rates regardless of where they live. FDAP rules apply only to foreign persons receiving U.S.-source income.
No. FDAP income is taxed on the gross amount with no deductions. This is the key difference from effectively connected income (ECI), which is deductible and taxed on net income. For rental income, the Net Income Election can convert FDAP to ECI treatment.
Submit a completed Form W-8BEN to the U.S. payer before the payment is made. The form identifies your treaty country and the specific treaty article that entitles you to a reduced rate. Without a valid W-8BEN, the payer must withhold at the 30% rate.
File Form 1040-NR at the end of the tax year and claim the overwithholding as a refund. Attach the Form 1042-S you received from the payer as proof of the amount withheld.
By default, yes. U.S. rental income paid to a nonresident alien is FDAP and is taxed at 30% on gross rent. However, you can make the Net Income Election (IRC 871(d)) to treat it as effectively connected income instead, which allows deductions and graduated tax rates. This election almost always results in significantly lower taxes.
Generally, no. Capital gains of nonresident aliens who are present in the U.S. for fewer than 183 days during the tax year are not subject to U.S. tax. However, gains from the sale of U.S. real property interests are taxed under FIRPTA as effectively connected income, and capital gains of NRAs present in the U.S. for 183 days or more may be taxed at 30%.
