F-1 OPT students with a U.S. LLC: tax rules

F-1 students on OPT can operate a business through an LLC, but the work must be directly related to the student's major field of study. This means a computer science graduate could run a web development LLC, but not an unrelated catering business. The LLC activities must constitute legitimate employment in the student's field, and the student must work at least 20 hours per week in activities related to their major.

USCIS permits self-employment during OPT as long as you can demonstrate that the work is related to your field of study. You must register the business and obtain proper business licenses. You should report your self-employment to your school's Designated School Official (DSO) and update your SEVIS record. The DSO will need to verify that your self-employment meets the OPT requirements.

F-1 students are generally considered nonresident aliens for tax purposes during their first five calendar years in the U.S. This is because F-1 visa holders are exempt individuals under the substantial presence test for up to five years. As a nonresident alien, you would file Form 1040-NR instead of Form 1040. However, if you have been in the U.S. for more than five years, you may become a resident alien for tax purposes.

F-1 students who are nonresident aliens are exempt from FICA taxes (Social Security and Medicare) on wages earned from employment. However, LLC self-employment income presents a more complex situation. The FICA exemption for F-1 students applies to services performed as an employee, not to self-employment income. Self-employment tax is governed by different provisions, and nonresident aliens are generally not subject to self-employment tax on U.S.-sourced income. Consult a tax professional to determine your specific obligations.

As a nonresident alien F-1 student, report your LLC income on Form 1040-NR. If the LLC is a single-member disregarded entity, the income flows through to your personal return. You must also file Form 8843 to claim your exempt individual status. If you have a tax treaty between your home country and the U.S., you may be eligible for reduced tax rates or exemptions on certain income. File Form 8833 to claim treaty benefits.

Keep thorough records demonstrating the connection between your LLC work and your field of study. Report your self-employment to your DSO immediately. File all required tax forms on time. Maintain a clear separation between your OPT employment and any unpermitted activities. If your OPT expires, you must cease LLC operations unless you obtain a different work authorization.
