If you're an H1B visa holder in the U.S., understanding your tax obligations is critical. You’re taxed like a U.S. citizen, which means paying federal, state, local, and FICA taxes (Social Security and Medicare). Your tax residency status - resident alien or nonresident alien - determines whether you’re taxed on worldwide income or just U.S. income. Most H1B workers qualify as resident aliens under the Substantial Presence Test.

Key points to know:

• Federal Income Tax: Progressive rates from 10% to 37%. Your employer withholds taxes based on your W-4 form.
• FICA Taxes: 7.65% of your wages; matched by your employer.
• State and Local Taxes: Vary by state; some states like Texas and Florida have no income tax.
• Deductions and Credits: Resident aliens can claim the standard deduction ($15,750 for single filers in 2025) and other tax breaks.
• Tax Treaties: May reduce taxes or exempt FICA contributions for workers from certain countries.
• Filing Deadlines: Federal taxes are due April 15, with extensions available until October 15.

Non-compliance can lead to penalties, IRS audits, or visa issues. Filing accurately and on time is essential, and hiring a tax professional can help with complex situations, such as dual-status filing or claiming treaty benefits.

H-1B Visa Tax Rules: Resident vs Non-Resident | Full Breakdown

How to Determine Your Tax Residency Status

Your tax residency status dictates whether you owe taxes only on your U.S. income or on everything you earn worldwide. The IRS uses your physical presence in the U.S. to determine this status. Most H1B workers are considered resident aliens for tax purposes, even though they are classified as "nonimmigrants" under immigration law. Let’s break down the differences between resident and nonresident alien status.

Resident Alien vs. Nonresident Alien

If you're classified as a resident alien, you’ll need to report your worldwide income on Form 1040 - the same form used by U.S. citizens. This status allows you to claim the standard deduction ($14,600 for single filers in 2024) and most tax credits.

On the other hand, nonresident aliens are only taxed on income earned within the U.S. They file Form 1040-NR and have far fewer deduction options. However, both resident and nonresident aliens are subject to FICA taxes. Understanding your status helps clarify your filing obligations and the deductions available to you.

"A resident alien must pay tax on their income in the same way a US citizen does. You will be required to report your worldwide income, both from within the US and abroad." - Nita Nicole Upadhye, US Immigration Attorney

The Substantial Presence Test

The Substantial Presence Test (SPT) determines your tax residency based on the number of days you’ve been in the U.S. over a three-year period. You qualify as a resident alien under this test if you were present in the U.S. for:

• At least 31 days during the current year, and
• A total of 183 days over the past three years, calculated as:
  • All days in the current year
  • 1/3 of the days in the first preceding year
  • 1/6 of the days in the second preceding year

For example, let’s say you spent 210 days in the U.S. in 2020, 300 days in 2019, and 90 days in 2018. Your calculation would look like this:
210 + 100 (1/3 of 300) + 15 (1/6 of 90) = 325 days. Since 325 exceeds 183, you’d be considered a resident alien for 2020.

Unlike individuals on F-1 or J-1 visas, H1B workers don’t qualify for exemptions - every day in the U.S. counts. It’s crucial to keep an accurate record of your entry and exit dates to avoid any surprises. If you meet the SPT but were in the U.S. for fewer than 183 days in the current year, you might still qualify for the closer connection exception. By filing Form 8840, you can demonstrate stronger ties to your home country, which could impact your tax obligations. These details are essential for determining the correct tax forms to file and deductions you can claim.

Federal Income Tax Requirements

Once you've established your tax residency, it's time to understand your federal income tax responsibilities. As an H1B visa holder, you'll pay the same federal income tax rates as U.S. citizens. However, the forms you file and the deductions you can claim depend on whether you're classified as a resident or nonresident alien. While your employer withholds federal income tax from each paycheck based on the details you provide on Form W-4, it's ultimately your responsibility to ensure the correct amount is withheld and to file the appropriate tax return by the deadline.

H1B workers generally face an effective tax rate ranging from 20% to 35%. The U.S. tax system is progressive, meaning your income is taxed in portions across different brackets. For example, if you're a single filer earning $80,000, your income will be taxed at 10%, 12%, and 22% rates incrementally. This means only the portion of your income that falls into a specific bracket is taxed at that rate. You won't pay 22% on your entire income - just on the amount that fits into that bracket.

To stay compliant, it's important to review the 2025 tax brackets and the required forms.

2025 Federal Tax Brackets and Rates

Knowing where your income fits within the federal tax brackets can help you estimate your tax liability and plan effectively. The IRS adjusts these brackets annually to account for inflation. Below are the federal income tax rates for 2025, which you'll report in 2026:

Tax Rate	Single Filers	Married Filing Jointly	Head of Household
10%	$0 – $11,925	$0 – $23,850	$0 – $17,000
12%	$11,926 – $48,475	$23,851 – $96,950	$17,001 – $64,850
22%	$48,476 – $103,350	$96,951 – $206,700	$64,851 – $103,350
24%	$103,351 – $197,300	$206,701 – $394,600	$103,351 – $197,300
32%	$197,301 – $250,525	$394,601 – $501,050	$197,301 – $250,500
35%	$250,526 – $626,350	$501,051 – $751,600	$250,501 – $626,350
37%	$626,351 or more	$751,601 or more	$626,351 or more

For instance, if you're an H1B worker earning $120,000 as a software engineer, you'll fall into the 24% marginal tax bracket as a single filer. However, your effective tax rate - the average rate you pay across all brackets - will likely be much lower, around 18–20% for federal income tax alone, before factoring in FICA, state, and local taxes.

Once you've determined your tax bracket, the next step is understanding the necessary tax forms.

Required Tax Forms

The forms you need to file depend on your tax residency status and when you complete them. Start with Form W-4, which helps set your federal withholding. If you're a resident alien, you'll use Form 1040 to file your taxes, while nonresident aliens must file using Form 1040-NR.

Resident aliens are required to report their worldwide income on Form 1040, which includes any earnings from their home country. Nonresident aliens, however, only need to report U.S.-sourced income on Form 1040-NR.

"Nonresident aliens are generally subject to U.S. income tax only on their U.S. source income." - IRS

If you're claiming benefits under a tax treaty between the U.S. and your home country, you may need to file Form 8833 to document your treaty-based return position. Additionally, if you're claiming treaty exemptions on personal services income, you should submit Form 8233 to your employer to reduce withholding at the source.

Filing the correct forms is crucial to avoid unnecessary complications with the IRS or potential visa issues.

FICA and Other Federal Taxes

H1B workers, like other employees in the U.S., are subject to more than just federal income tax. Additional mandatory withholdings fund vital social programs, and these deductions are taken from every paycheck. Unlike some other visa categories, H1B holders are not exempt from these obligations.

Social Security and Medicare Taxes

If you're on an H1B visa, FICA (Federal Insurance Contributions Act) taxes are unavoidable. Every paycheck sees 7.65% of your gross wages deducted: 6.2% goes toward Social Security, while 1.45% funds Medicare. Your employer matches this amount, effectively doubling the total contribution to 15.3% of your wages.

"An H1-B alien who is paid wages in exchange for personal services performed within the United States is liable for U.S. Social Security and Medicare taxes on such wages, regardless of whether he or she is a U.S. resident alien or nonresident alien." - IRS

This rule applies whether you're considered a resident or nonresident alien for tax purposes. Unlike F-1 students or J-1 scholars, who may qualify for temporary FICA exemptions, H1B workers contribute from the very beginning. It's a good idea to regularly check your pay stubs to ensure accurate deductions and avoid compliance issues.

There is, however, a key exception: if your home country has a Totalization Agreement with the U.S., you might be exempt from FICA taxes. Countries like India, the United Kingdom, Germany, and South Korea have these agreements to prevent double taxation on social security. To claim this exemption, you'll need a Certificate of Coverage from your home country's social security agency, which you must provide to your U.S. employer.

Additional Federal Taxes

Beyond FICA, H1B workers are also impacted by other federal taxes. For example, the Federal Unemployment Tax Act (FUTA) applies, but this tax is entirely paid by your employer, so you won't see it as a deduction on your paycheck. FUTA helps fund state unemployment programs and workforce agencies.

If you earn non-wage income, such as interest, dividends, or royalties, the tax rules depend on your residency status. Nonresident aliens face a 30% withholding on this type of income, known as FDAP (Fixed, Determinable, Annual, or Periodical) income, unless a tax treaty between the U.S. and your home country specifies a reduced rate. Resident aliens, on the other hand, must provide their SSN or ITIN to avoid a 28% backup withholding on these earnings.

Tax Type	Employee Rate	Employer Rate	Notes
Social Security	6.2%	6.2%	Mandatory withholding on wages
Medicare	1.45%	1.45%	Mandatory withholding on wages
FUTA	0%	Paid by Employer	Federal Unemployment Tax
FDAP (Nonresidents)	30%	N/A	Non-wage income unless treaty applies
Backup Withholding (Residents)	28%	N/A	Applied if TIN not provided

To avoid unnecessary backup withholding, always provide your SSN or ITIN to institutions like banks or brokerages that pay you interest or dividends. This simple step ensures you keep more of your earnings throughout the year.

State and Local Tax Rules

Once you’ve got a handle on your federal tax obligations, it’s time to dive into how state and local tax rules can impact your overall liability. Federal taxes are just the start - state and local taxes can vary significantly depending on where you live and work. Your state of residence determines whether you’ll owe additional income tax, and in some cases, even your city might tack on extra taxes.

State income tax rates generally range from 0% to 10% of your gross income, with local city taxes adding another 1% to 4% in some areas. Your employer uses the address listed on your Form W-4 to withhold these taxes, so it’s important to keep that information up-to-date. If you move between states during the year, you’ll likely need to file as a part-year resident in both states. Understanding these rules is key to managing your overall tax situation.

States With No Income Tax

If you’re an H1B worker living in Alaska, Florida, Nevada, South Dakota, Texas, Washington, or Wyoming, you’re in luck - these states don’t impose personal income tax on wages. That means you’ll only deal with federal income tax and FICA contributions, with no state-level withholding appearing on your paycheck.

Two other states - New Hampshire and Tennessee - don’t tax wages but do tax income from interest and dividends. For most H1B workers who earn primarily through employment, these states function similarly to the seven no-tax states.

However, living in a no-tax state doesn’t mean you’re off the hook entirely. You’ll still owe full federal taxes and FICA contributions, and any applicable local income taxes will still apply. That said, skipping state income tax can save higher earners thousands of dollars each year.

State Tax Filing Requirements

Most states require H1B workers to file a state tax return by April 15, which aligns with the federal deadline. For example, for the 2025 tax year, your state return will be due by April 15, 2026. If you need more time, filing Form 4868 for a federal extension typically extends your state deadline to October 15, though this depends on the state.

"In such a situation [living in one state and working in another], you may need to file tax returns in both states, and you will usually pay the higher of the two states' taxes." - Sprintax

Things get trickier if you live in one state and work in another. For example, if you live in New Jersey but work in New York, you’ll usually file as a resident in your home state and as a nonresident in your work state. Many states offer tax credits to avoid double taxation, and some have reciprocity agreements that allow you to file only in your state of residence.

It’s also worth noting that your state residency status for tax purposes may differ from your federal "resident alien" classification. Since each state has its own residency rules, make sure you understand the specific requirements where you live. Your W-2 form (Boxes 15-20) will show state and local tax withholdings, making it easy to confirm what’s been deducted throughout the year.

Finally, keeping organized records of your state and local tax returns is essential - not just for IRS compliance, but also for immigration purposes. USCIS may review these documents during H1B renewals or green card applications, so having everything in order protects both your financial and immigration status.

Tax Deductions and Credits Available to H1B Workers

Filing your taxes accurately is one thing, but knowing how to claim deductions and treaty benefits can make a huge difference in how much you owe. Whether you’re classified as a resident alien or a nonresident alien for tax purposes will largely determine what breaks you can take advantage of. Resident aliens typically enjoy the same tax benefits as U.S. citizens, while nonresident aliens face stricter limitations.

For 2025, the standard deduction is set at $15,750 for single filers and $31,500 for married couples filing jointly. Resident aliens can claim this deduction automatically. On the other hand, nonresident aliens filing Form 1040-NR generally can’t claim the standard deduction and must itemize instead. However, itemizing usually doesn’t provide much benefit to H1B workers unless they have significant qualifying expenses.

Reducing Your Adjusted Gross Income (AGI)

Beyond the standard deduction, there are "above-the-line" deductions that can lower your Adjusted Gross Income (AGI) directly. These include:

• Student loan interest: Deduct up to $2,500 if your modified AGI is under $85,000 (for single filers).
• Traditional IRA contributions: Deduct up to $7,000, or $8,000 if you’re 50 or older.
• Health Savings Account (HSA) contributions: Deduct up to $4,300 for individuals or $8,550 for families, provided you have a high-deductible health plan.

These contributions reduce your taxable income dollar-for-dollar, making them highly effective for lowering your tax bill.

In 2025, there are also temporary deductions you can claim, such as:

• Car loan interest: Up to $10,000, but only for vehicles assembled in the U.S.
• Tips: Deduct up to $25,000.
• Overtime pay: Deduct up to $12,500, with these benefits phasing out for incomes above $150,000.

Additionally, the State and Local Tax (SALT) deduction cap has been raised from $10,000 to $40,000 for taxpayers earning under $500,000, which is especially helpful for those in high-tax states.

Standard Deductions and Itemizing

The standard deduction is the go-to tax break for most H1B workers. For 2025, single filers can claim $15,750, while married couples filing jointly can claim $31,500 - no receipts or proof of expenses needed.

If your qualifying itemized deductions exceed the standard deduction, you can choose to itemize instead. Common itemized deductions include:

• Mortgage interest
• State and local taxes (up to $40,000 if your income is under $500,000)
• Charitable contributions
• Medical expenses exceeding 7.5% of your AGI

However, unless you own property or have substantial medical expenses, the standard deduction usually offers more savings.

One important note: H1B workers can no longer deduct moving expenses for job relocations. This deduction is now limited to active-duty military members moving due to a permanent change of station.

Deduction Type	2025 Limit (Single)	Eligibility Notes
Standard Deduction	$15,750	Resident aliens only
Student Loan Interest	$2,500	Phase-out starts at $85,000 MAGI
SALT Deduction	$40,000	For income under $500,000
IRA Contribution	$7,000	$8,000 if age 50+
HSA Contribution	$4,300	Requires high-deductible health plan
Car Loan Interest	$10,000	U.S.-assembled vehicles only

Tax Treaties and Benefits

Tax treaties can offer additional ways to reduce your tax burden. If your home country has a tax treaty with the U.S., you might qualify for reduced tax rates or exemptions on certain types of income. These treaties aim to prevent double taxation, which is especially helpful for H1B workers classified as nonresident aliens or those with income from their home country.

Key income types covered by treaties include:

• Wages (personal services income)
• Interest
• Dividends
• Royalties

For example, nonresident aliens from treaty countries may qualify for exemptions or reduced withholding rates. To claim these benefits on wages, submit Form 8233 to your employer before payments are made. For other income types like interest or dividends, use Form W-8BEN. If you didn’t file these forms during the year, you can still claim treaty benefits when filing your annual return using Form 1040-NR.

Another treaty-related perk is Totalization Agreements, which can exempt you from paying U.S. Social Security and Medicare (FICA) taxes if you’re covered by your home country’s social security system. Countries with these agreements include Germany, India, Japan, South Korea, and the United Kingdom. To claim this exemption, secure a "Certificate of Coverage" from your home country’s social security agency and provide it to your employer.

For resident aliens, tax treaty benefits are more limited due to the "saving clause" present in most treaties. This clause allows the U.S. to tax its residents as if the treaty didn’t exist. However, there are exceptions. For instance, residents of Canada, Mexico, and South Korea, as well as certain students or business apprentices from India, may still qualify for the Child Tax Credit even as resident aliens.

If you’re relying on treaty provisions to reduce or eliminate U.S. taxes, you may need to disclose this to the IRS using Form 8833. This is especially important if you’re taking a position that overrides general tax laws. Failure to file this form when required can result in penalties, so consulting a tax professional is a smart move if you’re unsure about your situation.

Tax Filing Deadlines and Extensions

Federal Tax Deadlines

If you're an H1B worker, your federal tax return is due by April 15 each year. For the 2025 tax year, this means filing by April 15, 2026. Employers are required to provide your Form W-2 by January 31.

Need more time? You can file Form 4868 by April 15 to request an extension, giving you until October 15, 2026, to submit your return. However, keep in mind that this extension only applies to filing - not payment. Any taxes owed must still be paid by April 15 to avoid extra costs. Late payments incur daily compounded interest (typically around 7%-8%) and a 0.5% monthly penalty, capped at 25%. If you file more than 60 days late, the penalty jumps to the greater of $510 or 100% of the unpaid tax. To avoid these headaches, the IRS suggests e-filing, which is faster and provides instant confirmation that your return was received.

"Non-compliance with tax laws can lead to legal issues and jeopardize your visa status." - VisaVerge

State and Local Deadlines

After handling your federal taxes, don’t overlook state and local deadlines, as they can vary widely. While some states align with the federal April 15 deadline, others set their own timelines. For instance, Virginia requires filing by May 1, while states like California, New Jersey, and Illinois automatically extend their deadlines to match the federal October 15 date if you’ve filed for a federal extension.

However, not all states are this straightforward. States such as New York, Massachusetts, and Pennsylvania may require you to file a separate extension form by April 15, even if you’ve already filed for a federal extension. If you’re lucky enough to live in states like Alaska, Florida, Nevada, South Dakota, Texas, Washington, or Wyoming, you can skip this step entirely - these states don’t have income tax.

To avoid surprises, always check your state’s tax authority website for the latest details.

Here’s a quick overview of key deadlines:

Jurisdiction	2026 Filing Deadline	Extension Deadline
Federal (IRS)	April 15, 2026	October 15, 2026 (Form 4868)
Virginia	May 1, 2026	November 1, 2026
New York	April 15, 2026	October 15, 2026 (state request required)
Texas/Florida/Washington	No state income tax	N/A

Staying on top of these deadlines is critical for avoiding penalties and maintaining compliance, especially as an H1B worker. A little preparation can go a long way in ensuring smooth tax management.

How to Stay Tax Compliant as an H1B Worker

When to Hire a Tax Professional

Navigating U.S. tax laws as an H1B worker can get tricky, especially when dealing with residency changes, foreign assets, or multi-state employment. While some workers handle their own taxes, certain situations call for professional help.

For example, transitioning from F-1 or OPT status to H1B mid-year creates a dual-status tax year. This means you might need to file as both a nonresident and resident alien in the same year - a situation most tax software can’t handle. In such cases, platforms like Sprintax or a tax professional familiar with split-year returns can be invaluable.

If you have foreign income or assets, things get even more complicated. Owning rental property abroad, holding foreign bank accounts exceeding $10,000, or earning dividends from overseas investments means additional reporting requirements. Resident aliens must include these on their U.S. tax returns and may need to file FinCEN Form 114 (FBAR). Missing these filings can result in serious penalties - a risk a tax expert can help you avoid.

"I go to an accountant to file taxes – it costs ~$200 but it's peace of mind they will do everything correctly given the complexities." - H1B Worker

Tax treaties are another area where professional guidance can save you time and money. If your home country has a tax treaty with the U.S., you might qualify for reduced withholding or exemptions. However, claiming these benefits often requires filing Form 8833, which can be challenging without expert support. Similarly, if you’ve worked in multiple states, you may need to file additional returns.

Hiring a tax professional typically costs about $200. Immigration attorney Nita Nicole Upadhye advises, "If you are in doubt, it is recommended to seek guidance from specialists US tax advisers." This is especially important because non-compliance with tax laws could jeopardize your visa status.

Accurate tax filings not only protect your financial stability but also ensure your visa remains secure - both of which are crucial for a smooth job search and career progression.

Using scale.jobs for Job Search and Financial Planning

For H1B workers, maintaining stable employment is just as important as staying compliant with tax laws. That’s where scale.jobs can make a difference.

Your salary has a direct impact on your tax bracket, and with upcoming policy changes favoring higher-paid candidates, landing a role with Wage Level II or III can improve your chances during visa allocation. Scale.jobs offers a free salary predictor tool to estimate compensation for specific roles, helping you evaluate job offers and understand how they might affect your federal tax bracket (typically between 20% and 35%). This insight can also help you adjust your Form W-4 withholding to avoid underpayment penalties.

Additionally, scale.jobs keeps track of employment dates and U.S. presence - critical for meeting the Substantial Presence Test (183 days over three years), which determines your tax residency status.

Unlike automated job bots that often get flagged by applicant tracking systems, scale.jobs combines human-assisted application services with ATS-optimized resume builders. This approach results in callback rates between 25% and 47%, compared to the 2% average of AI-only tools, and boasts a 93% job placement rate within three months. Reliable job placement is essential for meeting both tax obligations and visa requirements.

Scale.jobs offers three service tiers:

• Free tools: Includes a job board, application tracker, and resume builder.
• AI Assistant Pro: Available for $9/month (introductory offer).
• Human Assistant services: Starts at $199 for 250 applications and includes real-time WhatsApp updates, proof-of-work screenshots, and a transparent flat-fee model.

Final Thoughts

Navigating the tax landscape as an H1B worker is not just a routine task - it's a critical part of safeguarding your financial well-being and maintaining your visa status. As outlined earlier, understanding whether you're classified as a resident or nonresident alien is key. This distinction determines if you're taxed on your worldwide income or only on U.S. earnings, which can have a significant impact on your overall tax liability. Mistakes in filing can lead to hefty penalties, so accuracy is non-negotiable.

Let’s talk numbers. Federal tax rates range from 10% to 37%, and when you add FICA taxes (7.65%), most H1B workers find themselves paying between 25% and 35% of their income in taxes. State and local taxes often add to this burden. However, taking advantage of deductions, like the $15,000 standard deduction for single filers, can lead to substantial savings.

"Non-compliance with tax laws can lead to legal issues and jeopardize your visa status." – VisaVerge

If you have foreign accounts exceeding $10,000, you’re required to report them to avoid penalties. Additionally, dual-status filing during transition years can be complex and often falls outside the capabilities of most tax software, making professional advice invaluable.

A quick recap: Use the 183-day Substantial Presence Test to monitor your U.S. residency status, keep detailed records of all income sources, and update your W-4 whenever your circumstances change. When things get tricky, consider spending around $200 on a qualified tax professional - it’s a small price to pay for avoiding costly mistakes. Staying on top of your tax obligations not only secures your H1B visa but also sets a solid foundation for advancing your career in the U.S. Proactive and timely tax compliance is the key to long-term success.

FAQs

What is the Substantial Presence Test, and how does it impact my taxes as an H1B worker?

The Substantial Presence Test helps determine if you're classified as a U.S. resident for tax purposes. To meet this test, you must be physically present in the U.S. for at least 31 days during the current year and 183 days over the past three years. Here's how the calculation works: count all the days you were present this year, add one-third of the days from the previous year, and one-sixth of the days from two years ago. If the total reaches 183 days or more, you're considered a resident alien for tax purposes.

As a resident alien, you're required to report your worldwide income and follow U.S. tax laws, including meeting filing deadlines. If you don't meet the Substantial Presence Test, you're classified as a nonresident alien, which means you're only taxed on income earned in the U.S. or tied to U.S. sources.

How do tax treaties benefit H1B visa holders?

Tax treaties play a crucial role for H1B visa holders by addressing the issue of double taxation. These agreements are designed to prevent individuals from being taxed on the same income in both the U.S. and their home country. By doing so, they can reduce or even eliminate withholding taxes, making it easier to comply with tax requirements. Additionally, tax treaties offer clear guidelines, helping ensure fair treatment and minimizing financial stress for those working abroad.

Do I need to file taxes in more than one state?

If you earned income in more than one state during the year, you might need to file taxes in multiple states. Generally, if you worked or received income in a state other than your home state, you’ll be required to file either a non-resident or part-year resident tax return for that state.

Tax laws and income thresholds vary by state, so it’s crucial to understand the specific requirements for each state where you earned income. The good news? Many home states provide tax credits to help reduce the impact of being taxed twice on the same income.
