If you landed in the US in the last year, this filing season is the first time you will interact directly with the IRS instead of hearing about it secondhand. The rules are not intuitive if you grew up filing taxes somewhere else. Nothing here is a substitute for a licensed preparer, but you should walk into that conversation already understanding the shape of your return.
Most new H-1B consultants share the same three questions: am I a resident or non-resident for tax purposes, what do I do with a W-2 versus a 1099, and what deduction actually applies to me. Get those three sorted and the rest of the return is mechanical.
Resident or Non-Resident? Why It Changes Everything
The IRS does not care about your visa category directly. It cares about a residency test applied every year, independent of immigration status. You can be on H-1B and still file as a non-resident alien in your first partial year, or you can be a resident alien for tax purposes almost immediately, depending on how many days you were physically present in the US.
This distinction matters because it determines which form you file (Form 1040 for residents, Form 1040-NR for non-residents), whether you can claim the standard deduction, and how your worldwide income is treated. Residents are taxed on worldwide income. Non-residents are generally taxed only on US-source income.
The Substantial Presence Test, Step by Step
This is the calculation that decides your status. It is called the Substantial Presence Test (SPT), and it is arithmetic, not opinion.
- Count the days you were physically present in the US during the current tax year. You need at least 31.
- Add: all days in the current year, plus one-third of the days in the prior year, plus one-sixth of the days in the year before that.
- If that weighted total is 183 or more, you are a resident alien for tax purposes for the current year.
Unlike F-1 students, H-1B holders are not exempt individuals under this test. Your days start counting from day one of physical presence. Most people who arrived on H-1B mid-year and stayed through year-end will cross 183 quickly and qualify as residents for that year, sometimes even under the First-Year Choice election if they arrive late in the year. If your arrival was very recent and you have not yet hit 183 weighted days, you may need to file as a dual-status alien for your first year, which is a specific, more complex return. This is exactly the kind of edge case where a CPA earns their fee.
W-2 vs 1099: Reading Your Income Documents
How you were paid changes what shows up in your mailbox in January.
| Document | Who receives it | What it means for you |
|---|---|---|
| Form W-2 | Employees, including most consultants placed through a staffing firm | Taxes already withheld: federal income tax, Social Security, Medicare. You reconcile, you do not calculate from scratch. |
| Form 1099-NEC | Independent contractors, corp-to-corp arrangements | No withholding. You are responsible for estimated quarterly taxes and self-employment tax on Schedule SE. |
| Form 1042-S | Non-resident aliens with certain treaty-exempt or reportable income | Often paired with Form 1040-NR filings; less common once you are a resident alien. |
One nuance specific to H-1B: unlike F-1 students on OPT, H-1B wages are always subject to Social Security and Medicare (FICA) withholding, regardless of residency status. If your employer did not withhold FICA on a W-2, that is worth raising with HR immediately, not in April.
The Standard Deduction and What You Can Actually Claim
Once you file as a resident alien, you become eligible for the standard deduction, the same as any US citizen. For the 2025 tax year (the return most newcomers reading this in 2026 will file), the standard deduction is projected at $15,000 for single filers and $30,000 for married filing jointly, per IRS inflation adjustments. Confirm the exact figure on IRS.gov before filing, since amounts are finalized annually.
Non-resident aliens filing Form 1040-NR generally cannot claim the standard deduction, with narrow exceptions under certain tax treaties (notably for some students and business apprentices from India under specific treaty language). This is another reason getting your residency status right at the start matters more than any other single decision on the return.
Do not assume deductions or credits you used at home apply here. Foreign tax credits, education credits, and dependent rules all have US-specific eligibility tests.
A Practical Filing Checklist
- Confirm your residency status using the Substantial Presence Test before choosing a form
- Gather all W-2s and/or 1099s from every employer or client you worked with during the year
- Have your Social Security Number or ITIN, and your visa entry/exit dates, ready
- Check whether your home country has a tax treaty with the US that affects specific income types
- Decide between standard deduction and itemizing, if you are eligible for either
- File by the deadline, typically April 15, or request an automatic extension using Form 4868
- Keep copies of everything for at least three years
None of this is tax advice. Every situation involving cross-border income, treaty benefits, or dual-status filings is different, and the cost of a mistake on your first US return, an amended filing, a missed treaty benefit, an incorrect residency claim, is almost always higher than the cost of an hour with a CPA or enrolled agent who handles international filers regularly.
