Understanding Federal and State Tax Forms

Why so many forms exist in the first place

Every U.S. tax return is built from a small stack of documents, and each one answers a different question for the tax authorities. Some forms report income you earned, some report tax already withheld from your paycheck, and some simply confirm your presence in the country during the year. For someone filing for the first time, the sheer number of acronyms can feel overwhelming, but each form has one narrow job.

International students usually deal with a smaller, more predictable set of forms than the general population, because scholarship money, wages, and treaty benefits are reported in specific, standardized ways. Learning the purpose of each document before you start typing numbers into a return removes most of the guesswork. This is also where software such as Sprintax becomes useful: it asks about your situation first and only then tells you which forms apply to you, rather than expecting you to already know.

Form W-2: wages and withholding from an employer

A W-2 is issued by any employer that paid you wages during the calendar year, whether that was on-campus work, an internship, or off-campus employment authorized under your visa category. It reports your total wages and the federal, state, and sometimes local income tax that was withheld from each paycheck. Employers must send this form by the end of January for the prior tax year.

If you worked more than one job, expect a separate W-2 from each employer. The withholding amounts shown on this form are compared against what you actually owe once your full return is calculated, which is why a return can result in a refund, a balance due, or neither.

Form 1042-S: scholarships, fellowships, and treaty-covered income

Form 1042-S is specific to nonresident taxpayers and reports income that is often taxed differently than ordinary wages, including scholarships, fellowship grants, and income covered by a tax treaty between the United States and another country. Unlike a W-2, a 1042-S can arrive later in the tax season, sometimes into March, because the university or institution issuing it has different filing deadlines.

Many students overlook this form simply because it looks unfamiliar next to a W-2, or because they assume scholarship money isn't taxable. Depending on how the funds were used, some or all of it may need to be reported. This is one area where a structured walkthrough, rather than a blank form, genuinely helps.

Form 8843: a statement, not a tax return

Form 8843 is unusual because it does not report income at all. It is a statement filed by nonresident students and scholars to explain their exempt days of presence in the United States for residency-counting purposes. Even a student with zero U.S. income in a given year is generally still expected to file this form if they were present in the country under an F, J, M, or Q visa category.

Because no income figures are involved, people sometimes assume Form 8843 is optional or unimportant. It is neither. It is the document that supports your claim to nonresident status, and skipping it can create confusion in future years if your residency timeline is ever questioned.

State tax forms: a separate layer on top of the federal return

Federal forms are only half the picture. Most states that collect income tax require their own return, using figures carried over from the federal forms but applying separate rules, rates, and thresholds. Some states have no income tax at all, which simplifies things considerably for students living there. Others require a return even if only a small amount of income was earned within the state.

State rules do not always mirror federal treaty positions, so a scholarship that is exempt federally might still be partially taxable at the state level, or vice versa. This is one of the more common points of confusion, and it is exactly the kind of variation a guided tool is built to sort through, form by form.
