IRS Publication 515 – IRS Forms, Instructions, Pubs 2026 – In the complex world of international taxation, understanding U.S. tax obligations for foreign income recipients is crucial for compliance. IRS Publication 515, officially titled “Withholding of Tax on Nonresident Aliens and Foreign Entities,” serves as an essential resource for withholding agents handling payments to foreign persons. This guide, updated for the 2025 tax year, outlines rules under Chapters 3 and 4 of the Internal Revenue Code, including sections 1441–1443 for general income tax withholding and 1471–1474 for FATCA (Foreign Account Tax Compliance Act) requirements. Whether you’re a business owner, payroll manager, or financial institution, mastering these guidelines helps avoid penalties and ensures accurate tax reporting.
This article breaks down the key elements of IRS Publication 515, including who must withhold, income types, rates, exemptions, treaties, and reporting. We’ll draw from the latest official IRS sources to provide accurate, up-to-date information as of 2026.
What Is IRS Publication 515?
IRS Publication 515 is a detailed manual designed for withholding agents—individuals or entities responsible for deducting and remitting U.S. taxes on payments made to non-U.S. residents. It covers withholding on U.S.-source income paid to nonresident aliens, foreign corporations, partnerships, trusts, estates, governments, and international organizations.
The publication addresses both Chapter 3 withholding (on fixed or determinable annual or periodical income, or FDAP) and Chapter 4 FATCA withholding (on withholdable payments to foreign financial institutions and entities). It also includes rules for withholding on dispositions of U.S. real property interests (USRPI) under section 1445 and partnership income under section 1446. For the 2025 edition, it incorporates updates like e-filing requirements and treaty suspensions, making it vital for global transactions.
Who Must Withhold Tax Under IRS Publication 515?
Withholding agents are broadly defined as any U.S. or foreign person with control, receipt, custody, disposal, or payment authority over income subject to withholding. This includes individuals, corporations, partnerships, trusts, nominees, foreign intermediaries, U.S. branches of foreign banks, qualified intermediaries (QIs), withholding foreign partnerships (WPs), and withholding foreign trusts (WTs).
Agents are personally liable for the tax withheld, even if the payee isn’t ultimately liable. Withholding occurs at the time of payment on the gross amount, with a minimum 30% rate if the exact amount is unknown (but not exceeding 30%). Special entities like QIs, WPs, and WTs can assume primary withholding responsibilities under IRS agreements. No withholding is required on payments to U.S. persons, and employers handle wages for nonresident aliens separately.
Types of Income Subject to Withholding
Publication 515 categorizes income into several types, primarily focusing on U.S.-source income. Here’s a breakdown of key categories:
| Income Category | Examples | Key Notes |
|---|---|---|
| FDAP Income (Chapter 3) | Dividends, interest (excluding portfolio or bank deposit interest not effectively connected), royalties, rents, pensions, annuities, scholarships, grants, prizes, awards, REMIC excess inclusions, estate/trust/partnership distributable net income, compensation for personal services, gambling winnings, transportation income, original issue discount, alimony (if treaty applies post-2018), insurance proceeds (excluding surrenders), software licenses. | Subject to 30% default withholding unless exempt; includes dividend equivalents and contingent intellectual property payments. |
| Effectively Connected Income (ECTI/ECI) | Wages from U.S. services, U.S. trade or business income (e.g., real property if elected), partnership allocations. | Withheld by partnerships at 37% for noncorporate partners or 21% for corporate; exempt from Chapter 3/4 if documented on Form W-8ECI and includible in gross income. |
| USRPI-Related (Section 1445) | Gains from real property dispositions, USRPHC interests, certain PTP or trust interests. | Includes distributions treated as gains. |
| Partnership-Related (Section 1446) | ECTI allocations to foreign partners, PTP distributions or transfers. | 10% on PTP transfers unless exceptions apply. |
| Withholdable Payments (Chapter 4) | U.S.-source FDAP to foreign entities (e.g., dividends, substitute dividends). | Excludes short-term or grandfathered obligations; targets noncompliant FFIs. |
| Other Income | Wages (graduated rates if Form W-4 filed), racing purses (unless ECI), nonbusiness gambling winnings. | FICA/FUTA exemptions for F, J, M, Q visa holders on related activities. |
Exemptions apply to items like qualified scholarships for degree candidates or per diem for training.

Exemptions from Withholding Tax
Withholding isn’t required if proper documentation is provided, such as Form W-8 series (e.g., W-8BEN for individuals, W-8BEN-E for entities, W-8ECI for ECI). Key exemptions include:
- Portfolio interest in registered form (foreign-targeted, no 10% U.S. owners).
- Bank deposit interest not effectively connected.
- Short-term OID, nonbusiness gambling winnings, qualified scholarships, annuities (if 90%+ from U.S. employers or treaty residents).
- Income from active foreign businesses, foreign employers, or time-limited services (≤90 days/$3K).
- Payments to foreign governments, tax-exempt organizations, or visa holders for related activities.
- Chapter 4 exemptions for participating FFIs or exempt owners.
For USRPI/PTP, exemptions apply with certifications like non-foreign status or low ownership thresholds.
Tax Treaties and Reduced Withholding Rates
U.S. tax treaties can reduce or eliminate withholding on items like FDAP, services, pensions, scholarships, and gambling. To claim benefits, payees must be treaty country residents, beneficial owners, and meet limitation on benefits tests. Documentation via W-8BEN/W-8BEN-E or Form 8233 is required.
Recent changes include partial suspensions of treaties with Belarus (December 2024–December 2026) and Russia (August 2024 ongoing), and termination of the 1979 Hungary treaty (effective January 2024 for withholding). Always check IRS treaty tables for specifics.
Reporting and Filing Requirements
Withholding agents must report via:
- Form 1042-S: For Chapter 3/4 payments, including income codes (e.g., 1 for interest, 6 for dividends).
- Form 1042: Annual return, e-filed if threshold met (reduced to 10 returns starting 2024).
- Other forms: 1099 series, W-2, 941, 8804/8805 for partnerships, 8288 for USRPI.
