As new foreign workers in the US on visa sponsorship, taxes can be a handful. The confusion is always present for a newbie. Imagine that you are a new hire in the US, and upon getting your paycheck, you discover that it is short of your expectations.
Before you send that email to HR, know that the deduction is legal and not the fault of the employer. If you’re in search of clarification and want to get the latest and most accurate information about tax forms, deductions, and refund steps if you have overpaid, this article is for you.
You should be clueless in 2026, even when the system seems to tilt you towards that direction. The first step is to know your tax status.
Are you a resident or non-resident foreigner?
This is a critical determinant. Your Visa type doesn’t hold much substance now.
As a foreigner, you should consider the Substantial Presence Test and see if it applies to you. As a tip, know that your status CAN change at any time, and when it does, the taxation applied doesn’t remain the same. That is the mistake most people make. What exactly is the Substantial Presence Test?
According to the Internal Revenue Service (IRS) guide on physical presence rules and calculations, the Substantial Presence Test is used to decide if a non-U.S. citizen or non-permanent resident can be considered a U.S. resident for the sake of federal income tax. Those who meet the requirements are taxed on their worldwide income, requiring them in most cases to file standard resident tax returns.
The requirement to be met is in two sections generally known as the “183-Day Formula”.
- During the recent tax year, the foreigner must be physically present in the United States for a minimum of 31 days.
- The individual(s) must have spent a minimum of 183 days spread over 3 years. How is this determined?
- All the days the foreigner lived in the U.S. in the current calendar year + a third of the days they lived in the U.S. the previous year + a sixth of the days they lived in the second year must give at least 183 days.
Are there exceptions to this rule? Absolutely!
In some cases, a medical emergency causes these foreigners to remain in the U.S. against their will. Those periods are not counted. Foreigners with the A, G, F, J, M, or Q visa types are also excluded. The rule is never fixed.
Some individuals automatically exempt from this rule are F-1 and J-1 students. For their first five years, they are not under the taxation rule. On the other hand, H-1B, L-1, O-1, and TN workers are automatically considered residents once they pass the 183-Day rule.
The next step after knowing your status is filling the required forms. Let’s dive into the forms one at a time. This article walks you through the questions, “Which forms do I fill”? and “What are the steps in filling them?”
Internal Revenue Service Forms — A Comprehensive Review
Below are forms you may be required to complete upon your arrival as foreign workers on U.S. visa sponsorship.
- FORM W-4: This is the Employee’s Withholding Certificate. Remember the scenario painted at the start of this article? This is where this form is applicable. The IRS authorises the employer on how much federal income tax to deduct from your paycheck. You are mandated to fill this form and submit to the employer.
Before you complete this form, you can look out for details like your personal information (name, address and Social Security number), filing status (single, married, or Head of household), signature and date. Failure to complete this part would make the form invalid. Other sections are not mandatory but help to make sure that the taxation is accurately applied. They apply to:
- Foreigners with multiple jobs or whose spouse also works.
- Foreigners with dependents under 17 years of age and with credits.
- Foreigners with other sources of income (interest, dividends, or retirement), special deductions and withholdings at the end of the paycheck.
- FORM W-2: This form is known as the Wage and Tax Statement. How is it used? The IRS receives this form to ascertain the wages an employee receives at the end of the year, as well as how much tax is applicable or should be deducted from their paycheck. It usually arrives at the end of January. Let’s go into detail.
The W-2 form must be completed by employees who earn over $600 at the end of the tax year and have income, Social Security, or medicare tax deducted.
The form must be filed with the Social Security Administration (SSA) by January 31 each year to ensure that the employees file their federal and state income tax returns on time.
What are details to look out for? As Foreign Workers on U.S. visa sponsorship, you and your employer would have to fill in your personal details (name, address, SSN, and Employer Identification Number). See here to learn how to read the boxes (1-20), including the taxpayer information.
- FORM 1040 or FORM 1040-NR: Form 1040 applies to U.S. residents, green card holders, or foreign nationals. It is called “the U.S. Individual Income Tax Return”. If you are a U.S. citizen who meets the substantial presence test, you have to fill out this form. Form 1040-NR, known as the U.S. Nonresident Alien Income Tax Return, applies to Foreign Workers on U.S. visa sponsorship who earned U.S.-sourced income like wages, scholarships or fellowships. They cannot be categorised as tax residents.
While your income earned outside of the United States is NOT calculated, the downside is that you cannot file as Head of Household or Married Filing Jointly.
At this point, let us look at the next form. If you want the complete details on Foreign Workers on US Visa Sponsorship 2026, continue reading to the end.
- FORM 8843: This is the Statement for Exempt Individuals and Individuals With a Medical Condition. This form is not considered a tax return but a statement used in line with the substantial presence test mentioned earlier. It applies to individuals schooling in the U.S. or those with a medical condition. Here’s the point people overlook: You are expected to fill out the form even if you are not earning in the U.S. Of course, it is for tax purposes, but even dependents and underage children MUST file the form.
- FORM 8833: Foreigners use Form 8833 to lay a treaty claim. In simple terms, it provides the Internal Revenue Service a legal basis to reduce your U.S. tax liability. How does this work? If you’re a dual resident who resides interchangeably in the U.S. and another country, you can claim a specific country’s residency under a tax treaty.
Trust me, nobody wants to be taxed twice! Speaking of treaties, let’s have a look at them briefly. This is the part most people overlook and lose a lot of money.
Tax Treaties: A Keen Look
Tax treaties are called double taxation agreements (DTAs). They are some form of agreement between two countries (in this case, the U.S. and the foreigner’s country of origin). Their sole aim is to ensure that the taxpayer isn’t taxed twice or doesn’t pay taxation at all. As Foreign Workers on U.S. visa sponsorship, you are granted a credit or exempted from taxation in the U.S. entirely if your income is taxed in both countries.
If you’re sponsored in the U.S., we have discussed what the first tax season actually looks like. Below is a concluding look at applicable deductions and how to successfully get a refund.
Tax Deductions. Yes or No?
If you’re currently a US resident, a standard tax deduction is guaranteed. For Foreign Workers on US Visa Sponsorship, it is unlikely. I know this is not the kind of news you want to hear, but there are other deductions you can receive aside from the treaties mentioned above. Well, just look at two common ones.
- Relocation expenses: There is no specific rule guiding this. It is based on a formal agreement between the employer and employee. Do not expect your employer to automatically reimburse you. It’s a good idea to ask your employer how they intend to report the reimbursement on Form W-2.
- School Credits: If you’re a student in the U.S. and are paying qualified tuition, you are eligible for education credits such as the American Opportunity Credit or the Lifetime Learning Credit.
Final Tips for Foreign Workers on US Visa Sponsorship 2026
The moment you get your paycheck, always try to ascertain if your employer is holding back your due wages. The W-4 form comes in handy when filing for such errors. Follow the tips below in addition.
- Ensure that you file the form that matches your status.

- As you draw nearer to the end of the month, that is, before your next paycheck, check the W-4 form, comparing it to what your tax status looks like.
