IRS Updates 2026 Form 1042-S Instructions: What Non-U.S. Recipients and U.S. Businesses Should Know

The IRS has updated its Form 1042-S information page and identified a September 14, 2026 change to the box 13 references in the instructions for the 2026 form. The current 2026 Form 1042-S was created on September 4, 2026. [1] [2]
The practical answer is straightforward: if a U.S. business, partnership, platform, financial institution, or other withholding agent makes certain reportable U.S.-source payments to a foreign person, the payer may need to use the current Form 1042-S and instructions. A foreign recipient should review the form carefully, confirm the income and withholding information, and determine whether a U.S. return such as Form 1040-NR or Form 1120-F may be required. The form itself does not issue an ITIN, create an EIN, determine immigration status, or automatically resolve the recipient’s filing obligation.
This update is especially relevant to non-U.S. founders, foreign investors, international contractors, foreign corporations, U.S. LLCs making payments abroad, and professionals responsible for withholding and information reporting.
What is Form 1042-S?
Form 1042-S is used to report certain U.S.-source income paid to foreign persons and amounts withheld from that income. The IRS also identifies specified federal procurement payments made to foreign persons that are subject to withholding under Internal Revenue Code section 5000C, as well as certain distributions of effectively connected income by a publicly traded partnership or nominee. [1]
The form is an information return. It generally tells the recipient and the IRS what was reported, the category of income, the gross amount, and the amount of federal tax withheld. It is not the same as a tax return, and receiving one does not by itself determine the final tax due.
| Document | General purpose | What it does not do |
|---|---|---|
| Form 1042-S | Reports certain U.S.-source income paid to foreign persons and withholding | It is not an ITIN application or a final tax assessment |
| Form W-8 series | Documents a foreign person’s status and, where applicable, treaty or chapter status for withholding | It does not itself create an ITIN or EIN |
| Form 1040-NR | Individual U.S. nonresident income tax return | It is not required in every case merely because a Form 1042-S exists |
| Form 1120-F | U.S. income tax return for a foreign corporation | It does not replace information reporting by a withholding agent |
| Form 1042 | Annual withholding tax return filed by a withholding agent | It is not the recipient’s individual tax return |
| ITIN | IRS-issued individual tax-processing number for an eligible person who cannot obtain an SSN | It does not authorize work or guarantee a refund |
| EIN | IRS-issued federal business tax identifier | It does not establish immigration status or automatically determine tax classification |
What changed in September 2026?
The IRS’s “About Form 1042-S” page lists a recent development dated September 14, 2026: changes to the box 13 references in the instructions for the 2026 Form 1042-S. The IRS page was last reviewed or updated on September 15, 2026. [1]
The change is technical, but technical changes matter because Form 1042-S contains multiple recipient-identification and status fields. The 2026 form includes fields for the recipient’s U.S. taxpayer identification number, foreign tax identification number, country code, global intermediary identification number where applicable, status codes, exemption codes, and account information. [2]
A payer should not reuse an older form or rely on an outdated copy of the instructions. A recipient should compare the form with the payment records and withholding documentation received from the payer.
Who may receive Form 1042-S?
A foreign individual may receive Form 1042-S for certain U.S.-source income. A foreign corporation, partnership, trust, or other foreign entity may also be involved in a payment that requires reporting. The exact reporting treatment depends on the type of income, the recipient’s status, the payer’s role, applicable withholding rules, documentation, and any treaty position.
Common situations can include interest, dividends, royalties, certain scholarship or fellowship payments, certain nonemployee compensation or other income categories, and other payments identified in the current Form 1042-S instructions. The presence of an international payment alone does not answer whether Form 1042-S is required.
For a U.S. LLC or corporation, the key question is often whether the business is acting as a withholding agent or making a payment subject to reporting. A business should not assume that an LLC formation document or EIN alone resolves the withholding analysis.
How should a foreign recipient read the 2026 form?
Check the payer and withholding agent
Boxes identifying the withholding agent and payer should be reviewed first. The 2026 form includes information such as the withholding agent’s EIN, legal name, address, country information, and status codes. The recipient should confirm that the payer and withholding agent match the underlying transaction.
Check the income code and gross amount
The income code and gross income amount help identify what the payer reported. The recipient should compare the reported amount with statements, contracts, account records, payment-platform reports, partnership information, or other documentation.
Check the tax withheld
The federal tax withheld and related credit fields should be reconciled with the amount actually withheld. An error can affect a later U.S. tax return, treaty claim, refund request, or tax-account record.
Check the identification fields
The form includes a field for the recipient’s U.S. TIN, if any, and a separate field for a foreign tax identification number where applicable. A U.S. TIN may be an SSN, ITIN, or another applicable taxpayer identification number. An EIN identifies a business and should not be used as though it were the recipient’s individual ITIN.
Check the country and status codes
Country codes, chapter 3 and chapter 4 status codes, exemption codes, and other fields can affect how the payment was reported. A recipient who believes a code is wrong should contact the payer or withholding agent promptly and keep written records of the correction request.
Does receiving Form 1042-S mean that a tax return is required?
Not automatically. The 2026 Form 1042-S itself states that, generally, a nonresident alien individual, nonresident alien fiduciary, or foreign corporation with U.S. income may have a U.S. filing obligation, including where income is effectively connected with a U.S. trade or business. It also describes circumstances in which a return may generally not be required when the person was not engaged in a U.S. trade or business and the U.S. tax liability was fully satisfied by withholding at source. [2]
The outcome depends on the recipient’s facts, income type, U.S. business activity, withholding, treaty position, and other applicable rules. A recipient should not treat the form as a universal filing instruction or as proof that no filing is needed.
An individual who must file may generally use Form 1040-NR, while a foreign corporation may generally use Form 1120-F. The correct return and reporting treatment should be determined from the current IRS instructions and, when necessary, professional tax advice.
What is the relationship between Form 1042-S and an ITIN?
An ITIN is an IRS-issued individual tax-processing number for an eligible person who cannot obtain an SSN. Form 1042-S may include the recipient’s U.S. TIN if the recipient has one, but Form 1042-S does not apply for an ITIN and does not replace Form W-7.
A foreign individual may need an ITIN for a U.S. federal tax return or another IRS-recognized purpose. The person must have a valid reason and submit the required documentation through the applicable process. An ITIN does not prove employment authorization, immigration status, or eligibility for a bank account.
A withholding agent should use the identification information supplied through the appropriate documentation and follow the current Form 1042-S instructions. A payer should not invent, substitute, or casually reuse a taxpayer number simply to complete a form.
What is the relationship between Form 1042-S and an EIN?
An EIN identifies a business for federal tax administration. The 2026 Form 1042-S includes the withholding agent’s EIN and may include other entity-identification fields, but an EIN does not determine whether a payment is reportable, whether withholding applies, or whether the recipient has a U.S. tax filing obligation.
For an international founder operating a U.S. LLC, the EIN can be important for business administration, banking, payroll, and federal tax filings. However, the business must still analyze its payments to foreign persons, documentation, withholding responsibilities, and information-return obligations.
What should U.S. LLCs and other businesses do now?
Use the current IRS materials
Businesses responsible for Form 1042-S reporting should download the current 2026 form and instructions from the IRS page rather than using an old internal template. The IRS specifically identifies the September 14 changes to the box 13 references.
Review foreign-payee documentation
A business should maintain the relevant W-8 documentation, payment records, treaty claims where applicable, tax-status information, and supporting contracts. The business should know which payments were made, to whom, under what classification, and whether tax was withheld.
Reconcile forms before furnishing them
Before providing Form 1042-S to a recipient or transmitting information to the IRS, reconcile the payee name, country, tax identification number, income code, gross amount, withholding amount, and status or exemption codes. A correction may be more efficient before a recipient files a return or requests a refund.
Keep a calendar
The IRS third-quarter tax calendar lists September 15, 2026 as a date for a withholding agent to file a calendar-year Form 1042 if a six-month extension was timely requested. It also lists deadlines for certain partnerships to file Forms 8804 and 8805 when an extension was timely requested. [3]
Those dates do not replace the current instructions for a specific filing. A business should confirm the deadline that applies to its tax year, filing status, extension, and form.
What should a foreign recipient do after receiving an incorrect form?
The recipient should first compare the form with payment statements and identify the exact discrepancy. The recipient should then contact the payer or withholding agent in writing, explain the requested correction, and retain the communication and supporting documents.
If the issue affects a tax return, withholding credit, treaty claim, or refund, the recipient should consider obtaining professional advice before filing. Filing a return with an incorrect information form can create avoidable delays, but a recipient should not ignore a filing deadline while waiting indefinitely for a corrected form.
The appropriate response depends on the type of error. A name or address issue may be different from an incorrect income code, missing TIN, wrong withholding amount, or incorrect chapter status.
How ITIN.com fits into this process
ITIN.com helps eligible clients prepare and coordinate ITIN and EIN services, LLC formation, and banking-assistance preparation. ITIN.com does not issue ITINs or EINs, decide whether Form 1042-S is required, determine a recipient’s tax liability, or guarantee a refund or bank-account approval.
The IRS issues ITINs and EINs. States form LLCs. Withholding agents prepare and file applicable information returns. Banks independently decide whether to approve accounts. A client with a Form 1042-S question may need a tax professional or CPA to assess the payment and filing consequences.
Bottom line
The IRS has updated its Form 1042-S materials for 2026, including a September 14 change to box 13 references in the instructions. Foreign recipients and U.S. businesses should use the current form, reconcile the identification and withholding fields, and distinguish Form 1042-S from Form 1040-NR, Form 1120-F, ITIN, EIN, and Form 1042.
For international founders and U.S. LLC owners, the main practical lesson is that a business tax ID and an individual tax-processing number serve different functions. Accurate information reporting requires current IRS instructions, consistent documentation, and a careful review of the specific payment.

Form 1042-S reporting and filing obligations depend on the payment, recipient, payer, documentation, withholding, and applicable law. Consult a qualified tax professional for advice on a specific situation.
