Most workers pay FICA, but some jobs and situations are carved out

Not everyone who works pays FICA taxes. The main exemptions are for certain religious groups, some government employees, and specific types of work. If you fall into one of these categories, you may not owe Social Security and Medicare taxes on your earnings — but the rules are narrow and the burden is usually on you to prove you may have access to.

The most common exemption is for members of certain religious communities that object to insurance on principle. The second-largest group is federal employees hired before 1984, who are covered by a different retirement system. Beyond that, exemptions exist for some state and local government workers, certain nonresident aliens, and a handful of other situations. Each has specific requirements and paperwork.

Key Takeaways

  • Members of recognized religious groups opposed to insurance can request FICA exemption by filing Form 4361 before age 18 and earning at least $400 that year.
  • Federal employees hired before 1984 are covered by the Civil Service Retirement System instead of Social Security and do not pay FICA on their federal salary.
  • Some state and local government workers do not pay FICA if they are covered by their employer's pension plan, though rules vary by state.
  • Nonresident aliens on certain visa types and some students on work-study do not pay Social Security tax, though Medicare tax rules differ.
  • If you claim an exemption you do not may have access to for, you remain liable for back taxes, penalties, and interest.

Religious group exemption: the most common route

Members of recognized religious sects, orders, or communities that object to accepting public insurance benefits can request exemption from FICA. The group must be recognized by the IRS as having this belief as a core tenet. The Amish, Mennonite, and some other Anabaptist communities are the largest groups using this exemption, but it is not limited to them.

To claim it, you file Form 4361 (Application for Exemption From Self-Employment Tax for Use by Members of Recognized Religious Sects) before you turn 18 and in the year you first have net earnings of $400 or more from self-employment. If you are an employee rather than self-employed, your employer must also agree not to withhold FICA. Once approved, the exemption is permanent — you do not renew it each year.

The IRS maintains a list of recognized groups. If your community is not on it, you can petition for recognition, but this is a separate process that takes time. Simply objecting to taxes on your own does not may have access to; the objection must be based on sincere religious belief shared by an organized group.

Federal employees hired before 1984

Federal civilian employees hired before January 1, 1984, are covered by the Civil Service Retirement System (CSRS) instead of Social Security. They do not pay FICA taxes on their federal salary. In exchange, they receive a pension calculated differently than Social Security benefits.

Federal employees hired on or after January 1, 1984, are covered by the Federal Employees Retirement System (FERS) and do pay FICA taxes like other workers. FERS employees also receive a pension, but it is smaller than CSRS and is meant to work alongside Social Security.

If you are a CSRS employee, your pay stub will show no Social Security or Medicare withholding on your federal salary. If you have other income outside federal employment, you may still owe FICA on that income. CSRS employees who work part-time or take a second job pay FICA on the non-federal earnings.

State and local government workers with pension plans

Some state and local government employees do not pay FICA if they are covered by their employer's pension plan. However, the rules vary significantly by state and by employer, and many government workers do pay FICA even though they also have a pension.

Generally, if your state or local employer has a may have access to pension plan and you are a member of it, you may be exempt from Social Security tax (the 6.2% portion of FICA). Medicare tax (the 1.45% portion) is usually still owed. Some states have negotiated different arrangements with the federal government, so you need to check with your employer's payroll office to know whether FICA is withheld from your check.

If you are unsure whether you pay FICA, look at your pay stub. If the lines for Social Security and Medicare withholding are blank or zero, you are not paying. If they show amounts, you are. Your employer's HR or payroll department can also tell you directly whether you are covered by FICA or by an alternative system.

Nonresident aliens and visa holders

Nonresident aliens on certain visa types do not pay Social Security tax, though the rules are complex and depend on the specific visa and the person's country of citizenship.

Students on F-1, J-1, M-1, or Q-1 visas are generally exempt from Social Security tax on wages earned in the United States, as long as they are not U.S. citizens or residents. However, they still pay Medicare tax. To claim the exemption, they must provide their employer with a completed Form W-4 and a statement of nonresident status.

Other visa holders — such as those on H-1B, L-1, or O-1 visas — typically do pay FICA taxes. The rules depend on whether the person is considered a U.S. resident for tax purposes, which is determined by the substantial presence test and other factors. If you are on a work visa and unsure whether you owe FICA, ask your employer's HR department or consult a tax professional familiar with immigration tax law.

Work-study students and certain other workers

Students employed through a federal work-study program are exempt from Social Security tax on those wages, but they still pay Medicare tax. Work-study is a federal financial aid program, and the exemption applies only to wages paid through the official work-study arrangement, not to other jobs the student may hold.

Certain other narrow categories also do not pay FICA: children under 18 working for a parent's sole proprietorship or partnership (though the parent must own the business outright), some employees of certain nonprofit organizations, and a few other situations. These exemptions are rare and have strict conditions.

If you think you might fall into one of these categories, check with your employer or a tax professional. The burden is on you to claim the exemption correctly, and claiming one you do not may have access to for can result in a bill for back taxes plus penalties and interest.

What happens if you claim an exemption you do not may have access to for

If you claim a FICA exemption — for example, by filing Form 4361 or by telling your employer you are exempt — and the IRS later determines you did not may have access to, you become liable for all the FICA taxes you should have paid, plus interest calculated from the date they were due. Penalties may also apply.

The IRS can audit your exemption claim years after you file it. If you are self-employed and claimed religious exemption, the IRS may ask for proof that you are a member of a recognized group and that the group's beliefs genuinely oppose insurance. If you cannot provide that proof, you owe the back taxes.

For this reason, do not claim an exemption unless you are certain you may have access to. If you are unsure, ask your employer's payroll department or speak with a tax professional before filing any exemption forms.

Frequently Asked Questions

Can I claim FICA exemption just because I do not believe in taxes?

No. Personal objection to taxes does not may have access to. The exemption is limited to members of recognized religious groups whose faith teaches opposition to insurance and public benefits. The IRS maintains a list of recognized groups, and your community must be on it or have petitioned for recognition.

If I am exempt from Social Security tax, am I also exempt from Medicare tax?

Not always. Religious group members and some government workers are exempt from Social Security tax but still pay Medicare tax. Nonresident students on certain visas are also exempt from Social Security but pay Medicare. The rules differ by category, so check the specific exemption that applies to you.

What if I was hired by a state agency but am not sure if I pay FICA?

Check your pay stub. If the Social Security and Medicare lines show zero or are blank, you do not pay FICA. If they show amounts withheld, you do. You can also ask your employer's payroll or HR office directly — they will know whether your position is covered by FICA or by an alternative retirement system.

Do I need to renew my FICA exemption every year?

No. Once your religious exemption is approved by the IRS, it is permanent. You do not file Form 4361 again. However, if your circumstances change — for example, if you leave the religious community — you may lose the exemption and become liable for FICA going forward.

Can I claim FICA exemption for some jobs but not others?

It depends on the type of exemption. Religious exemption applies to all your self-employment income once approved. For employees, if your main job is exempt (such as federal CSRS employment), you still pay FICA on other jobs. Check the rules for your specific situation.
