One timing point first. The 2026 filing season covers 2025 tax-year returns, so you use the 2025 form and instructions. A tax-year 2026 return is filed in 2027, and final instructions for it aren't out yet. Always check line references against the current IRS instructions before you file.
This guide walks through the decision path: confirm nonresident status, find your filing trigger, classify income, complete the schedules, apply any U.S.-Australia treaty position and meet the deadline.
Key Takeaways
- Filing depends on U.S. tax status, income type, withholding and treaty positions, not nationality.
- Effectively connected income and FDAP income follow different reporting and tax rules.
- Schedule OI, 8843, 8833 and W-7 apply only to specific circumstances.
- Australian, U.S. state and federal 1040-NR obligations are three separate questions.
What Is Form 1040-NR and Who Must File It?
Form 1040-NR reports income taxable under the nonresident rules. Form 1040 generally covers U.S. citizens and resident aliens, who report worldwide income.
Nonresidents can't use married filing jointly or head of household status, and different deduction and schedule rules apply.
Who generally has a filing obligation
Under the 2025 IRS instructions, the main triggers are:
- U.S. trade or business: you generally file even with no business income, no U.S.-source income, or income exempt under a treaty.
- U.S.-source income not fully taxed by withholding: for example, under-withheld income that is not effectively connected with a U.S. trade or business (non-ECI).
- Taxable scholarships or fellowships: net of any treaty exemption.
- Rental income: especially if you make a section 871(d) election to treat it as effectively connected income (ECI).
- Refund or treaty claims: recovering over-withheld tax, or establishing a treaty exemption for contractors.
Withholding isn't a universal exemption. If tax withheld fully satisfies your liability on non-ECI, that particular trigger disappears. Other triggers remain.
Certain temporarily present F, J, M and Q students with no income subject to section 871 tax do not need to file, though Form 8843 may still be required.
How to determine whether you are a nonresident alien
You are a U.S. resident if you meet either test in Publication 519:
- Green card test: lawful permanent resident status at any time during the calendar year.
- Substantial presence test: at least 31 days in the current year, plus 183 weighted days: all current-year days, one-third of prior-year days and one-sixth of second-prior-year days.
For 2025, count 2025, 2024 and 2023. The IRS example: 120 days in each year gives 120 + 40 + 20 = 180 weighted days, so you do not meet the test.
Other points to check:
- Exempt individuals: qualifying F, J, M and Q holders can exclude days. "Exempt" refers to day counting, not income-tax exemption.
- Closer connection: fewer than 183 actual U.S. days, a foreign tax home and closer foreign ties. Claim it on Form 8840.
- Dual-status years: you are a resident for part of the year and a nonresident for the rest.
An Australian tax resident can still be a U.S. nonresident alien. Australian residence alone doesn't meet the U.S. tests.
How to Complete the 2026 Form 1040-NR
Start with the main return
The form moves through identity details, filing status, income, adjustments, tax, withholding and payments, then refund or balance due. Use the current IRS form for exact line numbers.
Two points matter most:
- ECI wages from a W-2 go on line 1a. Treaty-exempt wages are excluded from that line.
- Worldwide income is not reported the way it is on Form 1040. You report only U.S.-taxable income, classified as ECI or non-ECI.
Form 1042-S withholding is claimed on 2025 line 25g. FIRPTA withholding shown on Form 8288-A goes on line 25f.
Complete the required and situation-specific schedules
- Schedule OI: Attach to every 1040-NR. Covers residency, days present, visa status and treaty information.
- Schedule NEC: Report tax on non-ECI, including relevant non-ECI capital gains.
- Schedule A (Form 1040-NR): Claim nonresident itemized deductions. Do not substitute the resident Schedule A.
- Schedule D or Form 4797: Report ECI capital gains and losses, and attach to the return.
Related forms that depend on your facts
| Form | When it applies |
|---|---|
| 8843 | Explains excluded days for exempt individuals; can be filed alone if no return is due |
| 8833 | Discloses treaty-based positions; mandatory for dual-resident tie-breaker claims |
| 8840 | Closer connection claim |
| Section 871(d) election | A statement, not a numbered form, identifying properties, dates and income |
| W-7 | ITIN application, generally submitted with the return |
How Income, Deductions and Tax Treaties Work
Effectively connected income versus FDAP income
ECI is U.S.-source income connected with a U.S. trade or business. You deduct allowable expenses, then pay graduated rates. It is reported on the main return and applicable schedules.
FDAP income includes interest, dividends, rent and royalties. Non-ECI generally faces a flat 30% on gross income, with no associated deductions. A treaty or statutory exemption may reduce that rate. Report it on Schedule NEC. FDAP can sometimes be reclassified as ECI.
Common income situations
- Services and wages: Source follows where the work is physically performed, not where the payer or contract sits. A U.S. client paying for work done from Australia does not make that income U.S.-source.
- Mixed U.S. and foreign work: employees generally allocate by workdays.
- U.S. real estate: FIRPTA withholding is generally 15% of the amount realised, not of the gain. The buyer files Forms 8288 and 8288-A.
- Dividends and interest: often non-ECI. Statutory bank-deposit and portfolio-interest exemptions may apply without a treaty.
Federal income tax is separate from immigration, payroll and state-tax questions.
Deductions, credits and the U.S.-Australia treaty
The standard deduction is generally unavailable to nonresidents. The India treaty exception for students and apprentices doesn't extend to Australians. Itemize on Schedule A (Form 1040-NR) instead, and expect limited credits.
The 1982 U.S.-Australia treaty, amended by a 2001 protocol, sets these ceilings:
- Dividends: generally 15%
- Interest: generally 10%
- Royalties: 5%
- Students: Article 20 can exempt qualifying outside-source maintenance and education payments, but not U.S. wages or grants
For dual residents, Article 4(2) applies a tie-breaker: permanent home, then habitual abode, then closer personal and economic relations. This claim requires Form 1040-NR with Form 8833.
Which certificate you give a payer matters:
- W-8BEN: non-service income.
- Form 8233: treaty-exempt personal services.
Treaty claims need supporting facts and documents.
How to File Form 1040-NR in 2026
Prepare the return and supporting documents
Work in this order:
- Confirm your tax status.
- Identify your filing trigger.
- Collect income statements.
- Classify ECI and FDAP income.
- Complete the schedules.
- Review treaty claims.
- Reconcile withholding and estimated payments.
Gather these documents where they apply:
- Forms W-2, 1042-S, 1099 and K-1
- FIRPTA documents
- Passport and visa records, plus entry and exit dates
- Prior U.S. returns and treaty paperwork
- Payment records and your SSN or ITIN
Choose e-file or paper filing and meet the deadline
Individual 1040-NR e-filing is available, but dual-status and fiscal-year returns are excluded. PDF attachments are generally supported. A return can't be e-filed using an ITIN in the calendar year it was assigned.
Paper addresses from the 2025 instructions:
- No payment: Department of the Treasury, Internal Revenue Service, Austin, TX 73301-0215, USA
- With payment: Internal Revenue Service, P.O. Box 1303, Charlotte, NC 28201-1303, USA
- New ITIN with W-7: Internal Revenue Service, ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342, USA
2025 returns (filed in 2026):
| Situation | Due date | With Form 4868 |
|---|---|---|
| Employee wages subject to U.S. withholding | 15 April 2026 | 15 October 2026 |
| No such wages | 15 June 2026 | 15 December 2026 |
For tax-year 2026 returns filed in 2027, confirm dates once the final instructions are released. An extension to file isn't an extension to pay, so interest and penalties can run from the original date. Late filing generally costs 5% per month up to 25%, per IRS Form 4868. State returns are separate.

Frequently Asked Questions
Who needs to file 1040NR?
Nonresident aliens with a U.S. trade or business, U.S.-source income not fully satisfied by withholding, taxable scholarships, or a refund or treaty claim generally file. Check the current instructions for less common triggers.
What is the difference between Form 1040 and Form 1040-NR?
Residency decides it. Form 1040 covers residents on worldwide income. Form 1040-NR covers nonresidents on U.S.-taxable income, with no joint filing, limited deductions, and Schedules OI and NEC.
Do Australian residents with U.S. income need to file Form 1040-NR?
Not by residence alone. The answer turns on U.S. tax status, income type and source, withholding, treaty claims and other triggers. Treaty exemption doesn't always remove the filing duty.
Can I claim benefits under the U.S.-Australia tax treaty on Form 1040-NR?
Yes, if you meet the specific article's conditions. You may need Form W-8BEN or 8233 for the payer, or Form 8833 and Schedule OI disclosures on the return.
Can I e-file Form 1040-NR from Australia?
Often yes, since the instructions accommodate foreign addresses. Dual-status, fiscal-year and new-ITIN returns must be paper-filed.
What if I do not have an SSN or ITIN?
File Form W-7 with your return, plus original or certified identity and foreign-status documents. A passport is generally the only stand-alone document. Don't use W-7 if you already hold or are eligible for an SSN.
