The forms, in plain English

Form 1040-NR

The US tax return for nonresident aliens. Wages, taxable scholarships, and business income connected to the US go here, at the same graduated rates residents pay. If you had US income and you are a nonresident, this is your return, not Form 1040.

Form 8843

A one page statement for exempt individuals. Every F, J, M and Q holder files it every year they are in the US, even with no income, and so does each dependent on F-2, J-2, M-2 or Q-2. Filed alone, it mails to a different IRS address than a return with a payment.

Form 1042-S

Issued by your university for treaty-exempt pay, scholarships, and other payments to foreign students. The income code and exemption code on this form decide how the money is taxed. Keep every copy: different income can mean several 1042-S forms in one year.

Schedule NEC and Schedule OI

Schedule NEC taxes US income that is not connected to a job or business (dividends, some interest, rents, royalties) at a flat 30 percent or a lower treaty rate. Schedule OI reports your visa, your countries, your treaty claims, and your days in the US. We fill OI from your residency answers, so you never answer twice.

Form 8833

The disclosure form for a treaty position that overrides the tax code. Many student treaty claims are exempt from it, but some are not, and missing it when it is required can mean a penalty. We check, and we include it when your claim needs it.

Forms 843 and 8316 (FICA refund)

If your employer withheld Social Security and Medicare tax while you were FICA exempt on an F or J visa, you ask the employer first. If they will not refund it, these two forms claim it back from the IRS. We prepare the whole package.

Deadlines that apply to you

Your caseDue date for tax year 2025
You had US wages with tax withheldApril 15, 2026
No wages with withholding, or 8843 onlyJune 15, 2026
Extension filed on time (Form 4868)October 15, 2026 to file, not to pay

Dates follow the IRS calendar and can shift for weekends and federal holidays. My1040NR shows your personal deadline on your dashboard, with the reason.

Can I get an extension to October 15?

For a real tax return, yes. For Form 8843 by itself, no. The difference matters:

Your situationExtension?
You file Form 1040-NR (you had U.S. income)Yes. File Form 4868 by your original deadline and the IRS automatically gives you 6 more months. If your deadline was April 15, 2026 (wages with U.S. withholding), you get until October 15, 2026. If your deadline was June 15, 2026 (no wages subject to withholding), Form 4868 filed by June 15 gives you until December 15, 2026: check the box on Form 4868 for a nonresident alien who did not receive wages subject to withholding. No reason is needed and nobody has to approve it.
You file only Form 8843 (no income)No extension exists. Form 4868 extends tax returns, and Form 8843 by itself is not a tax return. It is due June 15, 2026. If you attach your 8843 to a 1040-NR, the return's extension covers it.
You owe taxAn extension moves the filing deadline, never the payment deadline. Pay what you owe by your original deadline or interest and a late payment penalty keep running.
You missed the 8843 deadlineFile it as soon as you can anyway. Late is far better than never, but know the rule: if Form 8843 is not filed on time, the IRS can refuse to let you exclude your student days when your residency is counted, unless you can show clear and convincing evidence the days should be excluded.

Page 1 of your PDF is a mailing slip

Your PDF does not start with a tax form. It starts with a mailing slip made from your own answers. At the top, your name and return address (the sender). In the middle, in the largest type on the page, the one IRS address that matches your exact case, with a plain sentence saying why that address: a 1040-NR with no payment goes to a different place than a 1040-NR with a check inside, and an 8843 filed alone goes to a different place again. Under that, a tick-box list of everything in your envelope and a "before you seal it" checklist (signed, dated, copies kept, attachments in). At the bottom, inside a dashed cut line, the same addresses as a label you can cut out and tape to the envelope. See a sample mailing slip (PDF, fictional data).

How you get these forms from us: answer the questions in one session, download one PDF with every form filled in, print it, sign it, and mail it. We prepare PDFs only. We do not transmit or file anything for you, and we save nothing after your session ends.
