If you did not work and earn money in the United States in 2023, you only need to submit Form 8843. This form is mandatory for all international students, even if you did not work at all.
If you did work and earn money in the United States in 2023, you will need to submit Form 8843 and 1040NR. Instructions for the 1040NR can be found at https://www.irs.gov/pub/irs-pdf/i1040nr.pdf.
You may also need to submit Form 540NR for your California State Taxes. Your employer should supply you with the required W-2 forms that you will need to complete the tax forms. If you have not received any forms, please contact your employer.
You may come from a country that has a tax treaty with the US, you may check that at https://www.irs.gov/individuals/international-taxpayers/tax-treaties.
Some international students may receive this form from your health insurance company to help you prepare your taxes. The health
insurance company is trying to let the IRS know that you are covered, but they can only do this if they know your social security number
(SSN). However, as an international student, you likely do not have a SSN.
In this case, you have two options:
1) Disregard and form and do not do anything
OR
2) Reply back to the health insurance company to let them know you do not have a SSN to eliminate future correspondence for this matter.
If you DO have a social security number, then you probably did not receive this form.
If you did however, complete the form as necessary so they know your social security number and can therefore tell the IRS about your health insurance coverage for tax purposes.
