December creeps up fast. By now, your employer should be preparing your W-2 (the form showing how much you earned and what taxes were withheld), and you’re probably wondering: what else do I need to gather before tax season? If you’re a J-1 visa holder who worked in the U.S., you have a specific set of documents the IRS expects to see — and gathering them now, rather than scrambling in March, means a smooth filing and faster refund. This checklist walks you through every document you need, why you need it, and when it arrives.

What documents do J-1 tax filers actually need to gather by year-end?

The core documents you’ll need are: a W-2 from your U.S. employer, your paystubs (especially the final one), Form 8843 (if you’re a nonresident alien), proof of your J-1 status, and any receipts for deductions or credits you plan to claim. Not every J-1 needs every document — the exact list depends on your visa category, how long you’ve been in the U.S., and whether you qualify for certain exemptions. The good news is that most of these items are issued automatically or already in your possession.

It depends on your J-1 category and how long you’ve been here

First, you need to know your residency status for tax purposes. That status is determined by the IRS Substantial Presence Test, combined with your J-1 visa category. If you’re in the “student” category J-1, you can exclude your U.S. presence from the test for up to 5 calendar years; if you’re in a “teacher or trainee” category (interns, trainees, specialists, camp counselors, etc.), you can exclude only 2 of the last 6 calendar years, extendable to 4 in some cases. Once that exclusion window closes and you meet the Substantial Presence Test, you become a resident alien for tax purposes and must file Form 1040 instead of Form 1040-NR. According to the IRS, “J-1 aliens who are U.S. resident aliens for the entire taxable year must report their entire worldwide income on Form 1040, U.S. Individual Income Tax Return, in the same manner as if they were U.S. citizens.” Check the Substantial Presence Test tool to confirm your own status before you start gathering documents.

This matters because nonresident aliens and resident aliens file different forms, claim different deductions, and may qualify for different exemptions. A J-1 student in their first year typically files Form 1040-NR and includes Form 8843. A J-1 who has been here seven years and is now a resident alien files Form 1040, just like a U.S. citizen, and does not file Form 8843.

Your checklist: documents to gather right now

1. W-2 from your employer

Your employer must send you a copy of your W-2 by January 31, 2027 for the 2026 tax year. This form reports your wages, federal income tax withheld, and FICA (Social Security and Medicare) withholding. Keep it safe — you’ll need the exact figures to file. If you worked for more than one employer, you’ll receive one W-2 from each.

2. Final paystub from 2026

Don’t wait for the W-2. Grab your last paystub of the year now. It shows year-to-date totals and is useful for double-checking your W-2 when it arrives. If there’s a discrepancy, you’ll want to catch it early.

3. Form 8843 (if you’re a nonresident alien)

If you’re claiming an exemption from the Substantial Presence Test (because you’re a student or teacher/trainee within the exclusion window), you must file Form 8843 with your federal tax return. Your J-1 program sponsor or school should provide you with the dates you need to complete it. If you became a resident alien partway through 2026, you may need both Form 8843 (for the nonresident portion) and Form 1040 (for the resident portion) — your tax software or a preparer can help split the year correctly.

4. Proof of J-1 status

Keep a copy of your current DS-2019 (or equivalent J-1 documentation from your program sponsor). You don’t file it with the IRS, but it’s your proof of visa category and dates of program participation. If the IRS has questions about your residency or exemption claim, you’ll want this on hand.

5. FICA exemption letter (if applicable)

Many J-1 visa holders are exempt from paying Social Security and Medicare tax (FICA). If you hold that exemption and your employer withheld FICA anyway, you’ll need a copy of the exemption letter from your program sponsor to file Form 843 (a claim for refund of those taxes). Gather this now so you know whether you’re eligible to claim back FICA withholding.

6. Records of any side income or scholarships

If you received a scholarship, grant, or prize during 2026, or earned income outside your main W-2 (for example, tutoring or freelance work), gather those records now. U.S. tax law treats scholarship income and other earnings differently for nonresident and resident aliens, so documentation helps you file correctly.

7. Deduction or credit receipts (if you plan to itemize)

If you made large medical, charitable, or education expenses during 2026, keep receipts. Most J-1 nonresident aliens take the standard deduction and don’t itemize, but it’s worth knowing your options. Resident aliens may benefit from itemizing in some cases.

Where most J-1 filers go wrong at year-end

Misconception #1: “My employer will handle Form 8843 for me.” They won’t. Your employer issues the W-2; your school or J-1 sponsor provides the J-1 dates and program info you need to complete Form 8843. You have to file it with your federal return if you claim a nonresident exemption. Missing this form can void your exemption and create a tax compliance issue.

Misconception #2: “If FICA was withheld, it’s correct.” Many J-1 visa holders should not pay FICA at all. If your employer withheld it without confirming your exemption status, you may be owed a refund. Don’t assume it was right — check your exemption letter and compare it to your W-2 now, while there’s time to resolve it before you file.

Misconception #3: “I can file using general tax software built for U.S. residents.” A general-purpose consumer tax tool built for U.S. residents may not be designed for nonresident alien filing. It won’t prompt you for Form 8843, FICA exemption status, or treaty benefits specific to your home country. Using the wrong tool can lead to errors in residency classification or missed deductions. For J-1 tax refunds and reliable filing, use a platform built for your situation.

Frequently Asked Questions

When does my employer send my W-2?

By law, your employer must send you a copy of your W-2 by January 31 of the year following the tax year. For 2026 income, that’s January 31, 2027. They also file a copy with the Social Security Administration. If you don’t receive it by early February, contact your employer’s HR or payroll department right away.

Do I need to file Form 8843 even if I didn’t work the full year?

If you’re a nonresident alien (which includes most J-1 students and trainees in their first two years), you must file Form 8843 for any calendar year in which you were in J-1 status, even if you only worked part of the year. The form certifies your exemption from the Substantial Presence Test, and leaving it off your return can jeopardize that exemption.

What if I worked for two employers in 2026?

You’ll receive a W-2 from each employer. Report all of them on your tax return. The total income from both W-2s gets added together, and the total withholding from both is also reported. The IRS will see all of them — they’re matched to you by your Social Security number — so make sure you include every W-2 you received.

Should I wait for my W-2 before I start gathering other documents?

No. Start gathering everything else now — your paystubs, DS-2019, FICA exemption letter, receipts, and any proof of other income. When your W-2 arrives in late January, you’ll have everything else ready, and you can begin filing immediately instead of hunting for documents.

What happens if I lost my DS-2019 or can’t find my exemption letter?

Contact your J-1 program sponsor or school immediately. They can issue a replacement DS-2019 or a new exemption letter, but it takes time. Getting these documents sorted in December is much easier than chasing them down in February when you’re already trying to file. Most sponsors can provide duplicates quickly if you ask well before year-end.

Year-end is the right time to get organized. Gathering your W-2, paystubs, Form 8843 docs, FICA exemption letter, and DS-2019 now means you won’t scramble in March.
