Form 1042: The complete guide to IRS withholding tax returns for foreign persons (2026)
Form 1042 is the annual US tax return filed by withholding agents to report tax withheld on US-source income paid to foreign persons, including nonresident aliens, foreign corporations, and foreign partnerships.
Withholding agents file Form 1042 with the IRS to reconcile all payments of FDAP income made to foreign persons during the calendar year and the tax withheld on those payments. The return covers obligations under both chapter 3 and chapter 4 – FATCA – of the Internal Revenue Code.
The 1042 form is separate from Form 1042-S, which goes to each individual payee. All 1042 form tax obligations fall on the withholding agent, not the foreign payee.
If your organization makes even a single payment of FDAP income to a foreign person, you may qualify as a withholding agent and should assess your filing obligations.
Form 1042 is one of several international withholding forms that withholding agents may need to file alongside Forms W-8BEN, 1042-S, and 1042-T. This guide covers who must file, what income triggers the requirement, due dates for tax year 2025, withholding rates, and how to avoid the most common compliance mistakes.
What is Form 1042? The complete guide for withholding agents
IRS Form 1042 is the Annual Withholding Tax Return for US Source Income of Foreign Persons. Withholding agents use it to report the total amount of US-source FDAP income paid to foreign persons during the calendar year and the tax withheld on those payments.
The 1042 tax form applies to payments made under two separate frameworks.
Chapter 3 of the Internal Revenue Code governs withholding on payments to nonresident aliens and foreign entities. Chapter 4 – the FATCA framework – governs withholding on payments to non-participating foreign financial institutions and recalcitrant account holders.
Form 1042 is not the same as an income tax return filed by the payee. It is the withholding agent’s reconciliation of all amounts withheld and deposited during the year.
The payee receives Form 1042-S – a separate statement showing the income paid and tax withheld on their share.
A withholding agent can be any person or entity – a corporation, partnership, trust, individual, or institution – that controls, receives, or pays US-source income to a foreign person.
Who must file Form 1042? Understanding withholding agent responsibilities
Any person or entity – including individuals, corporations, trusts, and partnerships – that has control over or custody of income paid to a foreign person is considered a withholding agent and may be required to file Form 1042.
The Form 1042 filing requirements apply broadly. You do not need to be a financial institution or a large corporation to qualify.
Common categories of withholding agents:
- US corporations paying dividends to foreign shareholders
- Universities and schools paying scholarships or fellowships to international students
- Partnerships distributing income to foreign partners
- Employers paying wages or compensation to nonresident alien employees
- Qualified intermediaries acting on behalf of foreign payees
- US branches of foreign banks processing US-source payments
- Individuals paying rent, royalties, or other FDAP income to a foreign person
Even with zero withholding, tax form 1042 may still be required. The obligation to file is triggered by the payment, not by the amount of tax withheld.
What payments require a 1042? FDAP income explained
Form 1042 is required whenever a withholding agent pays Fixed, Determinable, Annual, or Periodical income – such as dividends, interest, rents, royalties, salaries, wages, premiums, annuities, or compensation – to a foreign person.
FDAP income is imposed under IRC Section 871(a) for nonresident alien individuals and Section 881(a) for foreign corporations, with the withholding obligation on that income arising under Sections 1441 and 1442.
Common FDAP payment categories:
- Dividends – from US corporations to foreign shareholders
- Interest – from US bank accounts, bonds, or debt instruments paid to foreign persons
- Rents – paid to foreign property owners for US real estate
- Royalties – for use of US intellectual property, patents, or copyrights
- Salaries, wages, and compensation – paid to nonresident alien employees for services performed in the US
- Scholarships and fellowships – the taxable portion paid to nonresident alien students
- Annuities and pensions – paid to foreign recipients from US sources
- Premiums – including insurance premiums paid to foreign insurers
Form 1042 vs Form 1042-S vs Form 1042-T: Key differences
While Form 1042 is the withholding agent’s annual tax return, Form 1042-S is the individual income statement given to each foreign payee – similar to how Form W-2 relates to Form 941.
| Form | Purpose | Who receives it |
|---|---|---|
| Form 1042 | Annual withholding tax return – reconciles total income paid, tax withheld, and deposits made | Filed with the IRS by the withholding agent |
| Form 1042-S | Payee-level information return showing income paid and tax withheld for each foreign recipient | Sent to each foreign payee and filed with the IRS |
| Form 1042-T | Transmittal form used when submitting paper copies of Form 1042-S to the IRS | Filed with the IRS as a cover sheet for paper 1042-S submissions |
The totals on Form 1042 must reconcile exactly with the aggregate of all Form 1042-S statements issued for the same tax year. A mismatch between the two triggers IRS notices and potential penalties.
Form 1042-S serves a similar function to a W-2 or 1099 – it tells the payee what was paid and what was withheld so they can file their own US tax return, typically Form 1040-NR.
Form 1042 due date and filing deadlines for tax year 2025
For tax year 2025, Form 1042 is generally due on March 15 of the following year – or the next business day when that date falls on a weekend or holiday. March 15, 2026 falls on a Sunday, so the due date is March 16, 2026.
| Milestone | Date |
|---|---|
| Form 1042 annual return due | March 16, 2026 |
| Form 1042-S due to recipients | March 16, 2026 |
| Form 1042-S due to IRS | March 16, 2026 |
| Extension via Form 7004 | 6-month extension available |
The 1042 due date is separate from the deposit schedule. Withholding agents must deposit withheld taxes throughout the year via EFTPS – the Electronic Federal Tax Payment System.
The frequency of deposits depends on the total amount withheld. Missing a deposit deadline during the year can trigger penalties even if the annual Form 1042 is filed on time.
Standard withholding rates under chapter 3 and chapter 4 – FATCA
The default withholding rate on US-source FDAP income paid to foreign persons is 30% under chapter 3, but treaty rates – often 0%, 5%, 10%, or 15% – can significantly reduce this burden.
1042 withholding operates under two parallel frameworks:
- Chapter 3 – applies to payments of FDAP income to nonresident aliens, foreign corporations, and other foreign persons. The standard rate is 30% unless a tax treaty or statutory exemption reduces it
- Chapter 4 – FATCA – applies at 30% on withholdable payments to non-participating foreign financial institutions and recalcitrant account holders. Chapter 4 withholding addresses FATCA compliance at the institutional level
Both Chapter 3 and Chapter 4 amounts are reconciled on the withholding tax Form 1042 at year-end. Each payment is categorized by income code, and the applicable withholding rate is recorded on the corresponding Form 1042-S.
How tax treaties reduce Form 1042 withholding obligations
A valid US income tax treaty can reduce or eliminate the 30% default withholding rate on specific income types – but the withholding agent must receive a properly completed Form W-8BEN or W-8BEN-E from the foreign payee before applying any reduced rate.
Treaty benefits are claimed by the foreign beneficial owner on the appropriate W-8 form. The withholding agent then reports the treaty-reduced rate on Form 1042-S using the applicable income code and exemption code.
Form 1042 withholding at a treaty-reduced rate shifts the documentation burden to the withholding agent. If the IRS audits the return and the agent cannot produce a valid, signed W-8 form supporting the reduced rate, the agent is liable for the difference between the treaty rate and the full 30%.
Common treaty-reduced rates include 0% on certain types of interest, 5%–15% on dividends depending on ownership percentage, and reduced rates on royalties and pensions.
Each treaty is different, and the correct rate depends on the specific article, the income type, and the payee’s treaty country and residence status.
E-filing requirements for Form 1042: What changed
Under current IRS rules, Form 1042 must be filed electronically through the IRS Modernized e-File (MeF) system if the withholding agent is a financial institution, is a partnership with more than 100 partners, or meets the aggregate 10-return e-filing threshold across all information return types. Any one of these three conditions triggers the requirement.
The e-filing mandate was established under regulations implementing the Taxpayer First Act.
Form 1042 filing must be done electronically if the withholding agent meets the aggregate 10-return threshold:
1. Count all information returns filed across all form types – not just Form 1042-S – to determine whether you meet the 10-return threshold
2. Withholding agents below the threshold may still file on paper, unless they are a financial institution or a partnership with more than 100 partners
3. Form 1042 and Form 1042-S are governed by the same e-filing triggers: financial institution status, a partnership with more than 100 partners, or filing 10 or more information returns of any type in the calendar year. Because the 10-return count is based on your total information returns – not a separate count for each form – meeting that threshold requires e-filing both Form 1042 and Form 1042-S for the same year.
4. Electronic filing of Form 1042 is submitted through the IRS Modernized e-File (MeF) system, using an IRS-approved MeF software provider. This is a separate system from FIRE, which handles Form 1042-S and Form 1099-series filings.
5. Financial institutions and partnerships with more than 100 partners must e-file Form 1042 regardless of how many information returns they file in total
If you file Form 1042 on paper when e-filing is required, the IRS may assess a penalty for failure to file in the required format.
How to complete Form 1042: Section-by-section overview
The core of Form 1042 is a line-by-line reconciliation of income paid, tax withheld at the applicable Chapter 3 or Chapter 4 rate, and deposits already remitted to the IRS throughout the year.
The IRS Form 1042 instructions walk through five major sections:
- Withholding agent identification and type – name, EIN, address, and entity classification of the filer
- Summary of US-source income subject to withholding – broken down by income code, with each code carrying its own withholding rate
- Total tax withheld and deposits made via EFTPS – the aggregate of all deposits made during the year
- Reconciliation – amounts withheld must match amounts deposited plus any balance due or overpayment
- Signature and certification – the withholding agent or authorized representative signs under penalties of perjury
Amounts reported on Form 1042 must reconcile exactly with the aggregate of all Form 1042-S statements issued for the same tax year. Any discrepancy will generate an IRS notice.
Where to file Form 1042: Paper returns are mailed to the Ogden Service Center. Electronic returns are submitted through the Modernized e-File (MeF) system. The mailing address and e-filing portal are listed in the current year’s Form 1042 instructions.
Reconcile Form 1042 totals with your aggregate Form 1042-S amounts before filing. The IRS cross-checks these automatically, and any mismatch generates a notice.
Scholarship and fellowship withholding: Form 1042 for universities and schools
US universities and educational institutions must file Form 1042 when they pay scholarships, fellowships, grants, or tuition waivers to nonresident alien students – even if the amount is partially or fully exempt under a tax treaty.
The taxable portion of a scholarship – amounts covering non-qualified expenses such as room and board – is subject to withholding.
For nonresident alien students on F, J, M, or Q visas, the withholding rate on the taxable portion is 14%, not the standard 30%.
Amounts that cover qualified tuition and related expenses are generally not subject to withholding. The distinction between qualified and non-qualified expenses determines the taxable amount.
The institution must obtain Form W-8BEN from each foreign student to document their nonresident alien status and any applicable treaty claim. Without it, the full withholding rate applies.
Penalties for failure to file or withhold on Form 1042
A withholding agent who fails to withhold the required tax is personally liable for the full amount of tax that should have been withheld, plus applicable interest and penalties – regardless of whether the foreign payee ultimately pays the tax.
Penalties apply across several categories of late or incorrect 1042 filings:
- Failure to file Form 1042 on time – penalties under IRC section 6651 apply, calculated as a percentage of the unpaid tax for each month the return is late
- Failure to deposit withheld taxes via EFTPS on schedule – separate deposit penalties apply even if the annual return is filed on time
- Failure to withhold the correct amount – the withholding agent owes the full under-withheld tax plus interest, regardless of whether the payee reports and pays
- Failure to furnish Form 1042-S to payees – information return penalties apply for each statement not provided by the due date
1042 filing requirements extend beyond the annual return. The withholding agent’s obligation includes timely deposits, accurate Form 1042-S statements, and correct application of withholding rates throughout the year.
How to request an extension for Form 1042
Filing Form 7004 by the Form 1042 due date automatically extends the filing deadline by 6 months, but withheld taxes must still be deposited on time regardless of any extension.
Steps to request an extension for 1042:
- File Form 7004 by the original due date of Form 1042 – March 16, 2026 for tax year 2025
- The extension grants an additional 6 months to file the return – extending the deadline to September 16, 2026.
- An extension to file does not extend the time to deposit withheld taxes – all EFTPS deposits must still be made on their regular schedule
A separate extension form – Form 8809 – is used to request an additional 30 days to file Form 1042-S with the IRS. To request more time to furnish Form 1042-S copies to recipients, use Form 15397, Application for Extension of Time to Furnish Recipient Statements. Form 7004, Form 8809, and Form 15397 serve different purposes and must be filed independently.
Form 1042 for nonresident alien real property income and FIRPTA
When a US buyer or other withholding agent pays proceeds from the sale of US real property to a foreign person, FIRPTA withholding obligations arise – and these amounts are reported on Form 8288, not Form 1042. Rental income paid to foreign property owners, however, is reported on Form 1042.
Ongoing rental income paid to a nonresident alien landlord is FDAP income subject to 30% withholding under chapter 3. That withholding is reported on Form 1042 and Form 1042-S.
A sale of US real property by a foreign person triggers FIRPTA withholding, which uses a separate reporting path through Form 8288.
The IRS is actively auditing withholding agents and property managers who fail to withhold on rental payments to nonresident alien property owners, making correct Form 1042 reporting on these payments especially important.
Withholding agents handling either rental payments or property sales to foreign persons should confirm which form applies before remitting tax.
Common Form 1042 mistakes and how to avoid them
One of the most costly Form 1042 mistakes is applying a treaty-reduced withholding rate without first obtaining a valid, signed Form W-8BEN or W-8BEN-E from the foreign payee.
Most frequent errors:
- Applying a reduced treaty rate without a valid W-8 form on file – the withholding agent becomes liable for the difference
- Using the wrong income code or exemption code on Form 1042-S – this creates mismatches with the IRS and can trigger audit exposure
- Not reconciling Form 1042 totals with aggregate Form 1042-S amounts – the IRS cross-checks these automatically
- Missing EFTPS deposit deadlines during the year – deposit penalties are separate from filing penalties
- Failing to file Form 1042 because no tax was withheld – the return may still be required if FDAP payments were made to foreign persons
Form 1042 for foreign nationals receiving US-source income
Foreign nationals receiving US-source income – including dividends from US stocks, royalties from US intellectual property, or wages from a US employer – will typically receive a Form 1042-S from their withholding agent, which they use to prepare their own US nonresident tax return on Form 1040-NR.
The foreign recipient is not responsible for filing Form 1042. That is the withholding agent’s obligation. The payee’s responsibility is to report the income on their own return and reconcile any over-withholding to claim a refund.
If you are a J-1 visa holder or other foreign national who received a Form 1042-S showing tax withheld, file Form 1040-NR to report the income.
If too much tax was withheld – for example, at 30% when a treaty entitled you to 15% – filing the return is how you claim the refund.
FAQ
Form 1042 is the Annual Withholding Tax Return for US Source Income of Foreign Persons. Withholding agents file it with the IRS to report the total US-source FDAP income paid to foreign persons during the calendar year and the tax withheld on those payments under Chapter 3 and Chapter 4.
For tax year 2025, the due date is March 16, 2026 – the next business day after March 15, which falls on a Sunday. A 6-month extension is available by filing Form 7004 by the original due date.
The extension applies to the return only, not to deposit obligations.
Form 1042 is the withholding agent’s annual tax return filed with the IRS. Form 1042-S is the payee-level information return sent to each foreign recipient.
Form 1042 reconciles all payments and deposits for the year. Form 1042-S shows each payee what income was paid and what tax was withheld on their share.
The withholding agent is personally liable for the full amount of tax that should have been withheld, plus interest and applicable penalties. This liability exists regardless of whether the foreign payee ultimately reports and pays the tax on their own return.
No. A valid, signed Form W-8BEN or W-8BEN-E must be on file before the withholding agent applies any treaty-reduced rate. Without proper documentation, the default 30% rate applies.
If the IRS audits and the agent cannot produce the W-8 form, the agent owes the difference.
In many cases, yes. If FDAP income was paid to a foreign person during the year, Form 1042 may be required even if the withholding rate was 0% under a treaty or statutory exemption. The obligation is triggered by the payment, not by the amount of tax.
A 1042 exchange allows certain shareholders to defer capital gains when they sell qualified securities to an Employee Stock Ownership Plan and reinvest in qualified replacement property under Internal Revenue Code Section 1042.
This is a completely different provision from Form 1042 withholding and has no connection to the withholding tax return for foreign persons.
No. CP2100 and CP2100A notices apply to the Form 1099 series and Form W-2G, and address backup withholding on those forms. They are not issued for Form 1042-S. If the IRS identifies a name or TIN mismatch on a Form 1042-S, the withholding agent instead needs to correct the underlying documentation (such as an updated Form W-8) and file a corrected Form 1042-S.
