Residency & Filing Status 2026

Strong Financial Factors in 2026

The Social Security and Medicare transition: FICA Transition.

The loss of the FICA exemption is the most short-term paycheck shock that professionals who have an F-1 (Student) or J-1 (Scholar) visa change into an H-1B will experience in 2026.

The Price: 7.65% (6.2% in the case of Social Security and 1.45% in the case of Medicare) of gross income will be removed at once.2 In the year 2026, the wage base maximum of Social Security is raised to 184, 500.3
The Trigger: Liability will be incurred upon your change in status to that of H-1B, although you may remain a Non-Resident of the federal income tax.

The Global Income vs. the one sourced in the U.S

After the Substantial Presence Test, once in 2026 the IRS considers you a U.S. person and taxed you as one.4

The Obligation: You should tax all your worldwide income including rental income in your home country along with the bank interest in foreign country and stock dividends.
FBAR & FATCA: When the total amount of your overseas accounts (including bank accounts) reaches or surpasses 10,000 dollars at any moment in 2026, you will have to submit an FBAR (Finance Form 114).5- IF your foreign assets are more than 50,000 dollars, you also need to file an FBAR (Form 8938 (FATCA)).

Totalization Agreements- Tax Treaties

To avoid the phenomenon of same taxation, the U.S. is a signatory to numerous treaties with various countries (e.g. India, UK, Canada).7

Treaty Benefits: You can have the ability to exempt part of your earnings or to make a so-called Standard Deduction equal to it even in the NRA status.
Action Needed: These benefits do not come automatically.8 You will have to claim them manually with Form 8833 or Form 8233.

Refund spoken and Compliance Warning

Non-Resident Deductions: By filing as an NRA (Form 1040-NR), you do not usually qualify to claim the Standard Deduction, and that is why you tend to be taxed more than the residents who earn the same income.
Filing Deadline: The tax due date is April 15, 2027. By the beginning of February, make sure you have your W-2 or 1042-S.
State & Local Differences: Texas and Florida do not collect any income tax; meanwhile, California and New York are free to impose an extra 8 percent to 13 percent of your income.

FAQs

I moved to the U.S. in October of 2026. Do I file as a resident?

Likely not. As you would not satisfy the 183-day rule on being a 2026 resident, you would either file as a Non-Resident Alien or a Dual-Status taxpayer in case you make the First-Year Election.

Yes. Most foreign banks today under FATCA file account balances of U.S. tax residents with the IRS.

Do I have a right to claim my spouse as a dependent?

You can not usually claim a spouse as a dependent in 2026 but with you both being a Resident to tax purposes then you can file a Joint Return and, in most cases, this will mean a much lower tax bracket.
