A physician can arrive in the United States on an H-1B visa, begin work at a hospital within days and receive a regular paycheck with taxes already withheld. That does not necessarily make physician H1B taxes straightforward. Your immigration status, tax residency, work locations, prior U.S. visits and compensation structure can all affect what return you file and what records you need.
For many physicians, the first filing season is where small setup issues become larger questions. A payroll department may withhold federal and state income taxes correctly based on the information it has, but it cannot determine every residency election, treaty position or state filing obligation for you. Addressing those questions before filing helps create a more accurate return and a clearer plan for the year ahead.
Why Physician H1B Taxes Start With Tax Residency
An H-1B visa authorizes employment. It does not, by itself, determine whether you are a resident or nonresident for federal income tax purposes. The Internal Revenue Service generally applies the substantial presence test, which considers days physically present in the United States during the current year and the two prior calendar years.
For an H-1B physician, days spent in the United States usually count toward this test. This differs from certain situations involving F or J visa holders, whose days may be excluded for a limited period under separate rules. A physician who previously trained in the United States, changed visa classifications or made multiple visits should review the full travel history rather than assume the first H-1B payroll date controls the answer.
If you meet the substantial presence test, you will generally file as a U.S. tax resident. That normally means reporting worldwide income, including certain foreign bank interest, foreign investment income or compensation earned before arriving in the United States. If you do not meet the test, you may generally file as a nonresident and report income connected to U.S. sources. Your first year can be more complicated because dual-status filing rules may apply when you are a nonresident for part of the year and a resident for another part.
The distinction matters beyond the form used. Filing status choices, available deductions, reporting of foreign income and certain information-reporting requirements can differ significantly between resident, nonresident and dual-status returns. A tax review should begin with entry and exit dates, not just the Form W-2.
Payroll Withholding Is a Starting Point, Not the Final Result
Most employed physicians receive Form W-2 wages from a hospital, health system, university or medical group. The form reports wages and payroll withholding, including federal income tax, state income tax where applicable, Social Security tax and Medicare tax. Those amounts are central to the return, but they do not establish the final tax due or refund.
H-1B employees are generally subject to Social Security and Medicare withholding. Do not assume that a payroll tax exception available to some students, trainees or scholars applies to an H-1B physician. If a payroll record appears incorrect, raise the question with the employer promptly. The employer may need to correct its records and issue an updated wage statement.
Physicians should also identify compensation that does not appear on their primary W-2. Common examples include moonlighting income, consulting work permitted under the applicable employment arrangement, speaking fees, signing or relocation payments and payments made after a job change. A payment reported on Form 1099 may require a different tax analysis than regular wages, particularly if self-employment tax or quarterly estimated tax payments are involved.
Employee business expenses are another frequent source of confusion. Licensing fees, professional dues, required uniforms, conferences and board-related costs may be personally paid, but federal deductibility for unreimbursed employee expenses is limited under current law. Some states follow different rules. Before assuming an expense will reduce taxes, separate what was reimbursed by the employer from what was paid personally and determine whether it is deductible on the relevant return.
First-Year Filing and Treaty Questions
A physician moving to the United States may have income from more than one country during the transition year. That can include wages earned before relocation, interest from foreign accounts, rental income or a payment from a prior employer. The question is not simply where the funds were deposited. Tax treatment often depends on when the income was earned, your tax residency at that time and the rules applicable to the type of income.
Tax treaty provisions can also be relevant, but a treaty benefit is not automatic because someone holds a passport from a treaty country. Eligibility can depend on residency, the type of income, the length and purpose of the U.S. stay and the specific language of the treaty. A claim that reduces withholding may still need to be supported on a U.S. tax return. In some cases, applying a treaty position can affect other filing requirements.
For the 2025 tax year, most individual federal income tax returns were due April 15, 2026. A filing extension can provide additional time to submit the return, but it does not extend the time to pay tax due. Physicians with a first-year residency change, foreign income or a treaty question benefit from organizing the analysis well before the filing deadline rather than relying on a last-minute extension.
If foreign financial accounts or assets are involved, additional reporting may be required depending on the facts and applicable thresholds. These forms can carry separate deadlines and reporting rules. Keep account statements, ownership records and year-end balances available so a qualified tax professional can determine whether a filing obligation exists.
State Taxes Follow Where You Work and Live
A physician may live in one state, work in another and receive income from multiple facilities. This is especially common for physicians who relocate midyear, work across state lines or cover shifts at different hospitals. State tax obligations are based on each state’s residency and sourcing rules, which do not always match federal treatment.
A move can create part-year resident returns in two states. Temporary assignments may create a nonresident filing requirement in the work state. Local taxes can also apply in some jurisdictions. Payroll withholding in one state does not eliminate the need to examine whether another state return is required.
Maintain a practical record of your home address changes, work locations, dates worked in each state and state tax withheld from every Form W-2 or Form 1099. This documentation helps support the allocation of income and reduces the risk of overlooking a state filing.
A Practical Recordkeeping System for H-1B Physicians
The strongest tax preparation process is built throughout the year. Keep a secure file with your visa documents, passport entry history, travel calendar, employment agreements, pay statements and year-end tax forms. If you have changed employers or immigration classifications, preserve those dates as well.
For income outside your primary position, retain contracts, invoices, payment records and expense documentation. For a relocation year, keep records of your former and current addresses, foreign income received after arrival and any tax paid to another country. If an employer offers a reimbursement program, save both the expense receipt and the reimbursement confirmation so the records tell the full story.
It is also useful to review your withholding after a major change, such as a spouse beginning U.S. employment, a move to another state or new independent contractor income. The goal is not to force a particular refund or balance due. It is to have payroll withholding and estimated payments reflect your current facts as closely as practical.
When a Tax Review Can Help
A physician’s tax situation deserves closer review when the first U.S. filing year includes a residency change, foreign income, treaty considerations, multiple states or compensation beyond a single W-2. These issues are manageable when they are organized early, but they can be difficult to reconstruct from incomplete records after year-end.
