Tax Tips for Foreigners Working in the U.S

The tax system in the U.S. keeps changing and is very complex. Most of the U.S. citizens find it difficult to understand their tax obligations, and foreign residents residing in the U.S. end up being more confused. It's common to have doubts like Do I need to pay U.S. income tax obligations or which which taxes am I required to pay to pay.

Everyone needs to understand their tax obligations to ensure compliance with U.S. laws. Although tax laws keep on changing, there are a few aspects that remain the same. Whether you are in the U.S. on a temporary visa or going to get permanent residency, it's important to stay aware of the basic rules to protect your hard-earned money. Keep reading further to know five essential tax tips for foreign workers in the U.S. to file their returns confidently and stay fully compliant with the IRS.

Key Takeaways
  • Your tax obligations depend entirely on whether the IRS classifies you as a resident or nonresident alien.
  • You will be considered a U.S. tax resident if you hold a green card or meet the substantial presence test.
  • The U.S. tax year follows the calendar year, with a strict filing and payment deadline of the 15th of April.
  • Before filing, you must secure a Social Security Number (SSN) or an Individual Taxpayer Identification Number (ITIN) via Form W-7.
  • You must file Form 1040-NR even if you have zero tax liability or low earnings, as it helps claim withheld refunds and comply with U.S. tax laws.
  • Non-resident students on F-1, J-1, M-1, or Q-1 visas are generally exempt from paying Social Security and Medicare taxes.

File a U.S. Income Tax Return as a Non-Resident Alien Living and Working in the US

Non-resident aliens must file an annual U.S. income tax return if they live, work, or conduct a business in the US. It includes non-resident aliens as students living in the US on an F visa, a J visa, an M visa, or a Q visa.

However, not every nonresident alien will fulfill the residency requirements that require you to file a U.S. income tax return. You will be considered a resident in the U.S. if you:

  • Hold a green card, or
  • Meet the substantial presence test.

To fulfill the substantial presence test, you must have been in the U.S. for at least 31 days of the current year. It also requires that you have spent 183 days in the US out of the previous 3-year period.

Moreover, the tax year for the US aligns with the calendar year. It means the taxable year starts on the 1st of January and ends on the 31st of December. You can file your U.S. tax return either online or mail your paper return, which is Form 1040-NR, to the Internal Revenue Service (IRS).

The deadline to file the U.S. income tax return is the 15th of April each year. So, you must ensure you file your return by this date and, if you have any outstanding tax liability, pay it off by this date. In case you fail to file by the due date, it will attract penalties and interest.

Get a Tax ID Number Before Filing a U.S. Income Tax Return

Before filing a U.S. income tax return, you must ensure that you have a government-issued tax ID. It can be a Social Security Number (SSN) or an Individual Taxpayer Identification Number (TIN). Fill out Form W-7, attach it to Form 1040-NR, and send the completed forms to the W-7 center.

Also, ensure you submit all the required documents as well. Include either original copies or certified copies issued to you by the relevant agency. You can even submit notarized copies if you are the spouse of an active member of the U.S. Armed Forces.

File a U.S. Income Tax Return Even with No Tax Liability

You might assume that you don't need to file a U.S. tax return if you have low earnings or haven't lived in the country long enough to gain residency status. You could be right. However, filing a tax return is still recommended because U.S. employers usually withhold taxes.

Not filing a U.S. income tax return as a non-resident could mean leaving your refunds with the U.S. government. So, it is advised to file your return even if you don't owe any taxes.

Additionally, to ensure compliance with the terms of your U.S. visa, you must file the return. The terms require you to adhere to all U.S. laws. So, you must comply with the immigration rules and USCIS tax return requirements if you want to update your visa terms or wish to apply for permanent residency.

Lower Your Taxes as a Non-U.S. Resident by Claiming the Benefits of Tax Treaties

The United States has tax agreements with several countries, which helps you prevents double taxation on the same income. You can claim the benefits of this provision if you are a researcher, student, trainee, or teacher in the US on a temporary visa.

However, you cannot reduce your tax liability using the tax treaty if you are considered a resident of the U.S. Check IRS publication 901 if you think you are eligible to claim the benefits of a tax treaty between the US and your home country. This will help you check whether there is an active tax treaty that you can use to save money on your U.S return.

You May Have to Pay Social Security and Medicare Taxes

This requirement depends on your residency status and the category of your visa. So, you may have to pay U.S. Medicare and Social Security taxes (FICA) if you are a U.S. resident or you are on an F-2 visa or an M-2 visa. Conversely, you don't need to pay Medicare and Social Security taxes if you are a non-U.S. resident on an F-1 visa, a J-1 visa, a Q-1 visa, or an M-1 visa.

However, these are not the fixed rules, and there are exceptions. If you are a student and you work at the same school where you study, you are exempt from paying FICA taxes. Additionally, you may also need to contribute to the Social Security program of your home country. However, in this case, you can claim relief through a Totalization Agreement between your home country and the United States.
