For almost every worker in the United States, there is no way to opt out of the OASDI tax. The 6.2% Social Security payroll tax (12.4% for the self-employed) is mandatory under federal law, and no line on any tax form lets an ordinary employee or contractor decline it.1Social Security Administration. What Are FICA and SECA Taxes? A handful of narrow exemptions exist for specific religious groups, certain clergy, some nonresident workers on temporary visas, some state and local government employees, and a few family and student situations. Each of them requires you to meet strict criteria, and most require you to permanently give up your right to Social Security benefits in exchange.
Why the Default Is Mandatory
The Federal Insurance Contributions Act requires employers to withhold Social Security and Medicare taxes from wages and match the employee’s share. Self-employed workers pay the equivalent amount themselves through the Self-Employment Contributions Act.1Social Security Administration. What Are FICA and SECA Taxes? Congress built the system to depend on broad participation: current workers fund current retirees, so individuals cannot leave at will.
The tax also builds your own record. In 2026 you earn one Social Security credit for every $1,890 in covered earnings, up to four credits a year, and you need 40 credits (about 10 years of work) to qualify for retirement benefits.2Social Security Administration. Social Security Credits and Benefit Eligibility The exemptions below don’t just save you the tax. They trade away benefit eligibility, and most of them do it irreversibly.
Religious Group Exemption: Form 4029
Members of certain religious communities can apply for a complete exemption from both Social Security and Medicare taxes using IRS Form 4029. To qualify, the religious group must have existed continuously since December 31, 1950, must have a practice of providing a reasonable standard of living for its dependent members, and must be conscientiously opposed to all public and private insurance, including Social Security, Medicare, and private life or disability coverage.3Internal Revenue Service. Form 4029, Application for Exemption From Social Security and Medicare Taxes and Waiver of Benefits
In practice, this exemption applies almost exclusively to Old Order Amish and certain Mennonite communities. A personal objection to government programs is not enough. The opposition has to come from the established teachings of a recognized religious group, and both the IRS and the Commissioner of Social Security must approve the application.4Internal Revenue Service. Publication 517 (2025), Social Security and Other Information for Members of the Clergy and Religious Workers
Approval is permanent. You waive all rights to Social Security retirement and disability benefits and to Medicare coverage, not just on future earnings but on wages and self-employment income you earned before the exemption too. Anyone who has already received Social Security benefits would need to repay them before applying.3Internal Revenue Service. Form 4029, Application for Exemption From Social Security and Medicare Taxes and Waiver of Benefits
Clergy Exemption: Form 4361
Ordained ministers, members of religious orders who have not taken a vow of poverty, and Christian Science practitioners can apply on Form 4361 for an exemption from the self-employment tax on their ministerial earnings. This one is individual rather than group-based, but it still requires a genuine religious or conscientious objection to accepting public insurance benefits, not a preference to invest the money elsewhere.5Internal Revenue Service. About Form 4361, Application for Exemption From Self-Employment Tax for Use by Ministers, Members of Religious Orders and Christian Science Practitioners
The deadline is unforgiving. Form 4361 must be filed by the due date, including extensions, of the tax return for the second year in which you had at least $400 of net self-employment earnings from ministerial services. The two years do not have to be consecutive. Miss that window and the exemption is gone; there is no late-filing option.4Internal Revenue Service. Publication 517 (2025), Social Security and Other Information for Members of the Clergy and Religious Workers
Approved ministers must inform the body that ordained, commissioned, or licensed them. The exemption is irrevocable once granted, so you cannot later choose to buy back in and start building credits. Anyone who previously filed Form 2031 to revoke an earlier exemption is permanently barred from reapplying.6Internal Revenue Service. Form 4361, Application for Exemption From Self-Employment Tax for Use by Ministers, Members of Religious Orders and Christian Science Practitioners
Nonresident Aliens on Temporary Visas
Foreign nationals working temporarily in the U.S. are exempt from OASDI tax while they remain nonresident aliens and their work fits the purpose of their visa. Students on F-1, J-1, or M-1 visas are exempt for their first five calendar years in the country as long as their employment is authorized and connected to their studies, such as on-campus work or practical training.7Internal Revenue Service. Foreign Student Liability for Social Security and Medicare Taxes
Scholars, professors, researchers, au pairs, and other non-student workers on J-1 or Q-1 visas are exempt for two calendar years, provided they stay nonresident aliens and their work stays within what the visa allows.8Internal Revenue Service. Alien Liability for Social Security and Medicare Taxes of Foreign Teachers, Foreign Researchers and Other Foreign Professionals Once someone becomes a resident alien under the IRS residency rules, these exemptions end even if the visa is still valid.
Detached Workers Under a Totalization Agreement
The United States has bilateral Social Security agreements with 30 countries, including Canada, the United Kingdom, Germany, Japan, and Australia.9Social Security Administration. Country List 3, International Programs These totalization agreements keep you from being taxed by both systems on the same earnings. The general rule is that you pay Social Security taxes only in the country where you are actually working.
Under the “detached worker” rule, if a U.S. employer temporarily sends you to work in one of these 30 countries for five years or less, you stay in the U.S. system and are exempt from paying into the foreign country’s program. You will need a certificate of coverage from the Social Security Administration to show the foreign tax authority.10Social Security Administration. U.S. International Social Security Agreements Self-employed workers in some agreement countries follow a different allocation, typically based on country of residence.
Some State and Local Government Positions
Not every public-sector worker pays OASDI. State and local government employees may be exempt if their positions are covered by a qualifying public retirement system that substitutes for Social Security.11Social Security Administration. How State and Local Government Employees Are Covered by Social Security and Medicare This affects many teachers, police officers, and firefighters, especially in states with large standalone pension systems.
Coverage depends on whether the state has a Section 218 agreement with the Social Security Administration. These agreements attach to positions, not people, so if your position is covered you pay the tax regardless of personal preference. Employees hired since July 1991 who are not in a qualifying retirement system and are not covered by a Section 218 agreement are generally required to pay OASDI tax.12Internal Revenue Service. State and Local Government Employees Social Security and Medicare Coverage This is not something you elect. It depends on the job.
Students Working for Their School
If you are enrolled and regularly attending classes at a school, college, or university, wages you earn from that same institution may be exempt from OASDI tax. The test is whether the job is secondary to your education. You must be at least a half-time student, and the exemption is lost if you qualify as a “professional employee,” meaning you are eligible for benefits like vacation, sick leave, retirement plan contributions, or reduced tuition beyond what teaching and research assistants receive.13Internal Revenue Service. Student FICA Exception
Full-time employees do not qualify regardless of enrollment. Under IRS rules, a normal work schedule of 40 hours or more per week makes you a full-time employee whose services are not secondary to a course of study.14eCFR. 26 CFR 31.3121(b)(10)-2 – Services Performed by Certain Students in the Employ of a School, College, or University The exception also does not reach work at an unrelated employer, even if you are a student somewhere else.
Children Working in a Parent’s Business
Wages paid to your child working in your sole proprietorship, or in a partnership where both partners are the child’s parents, are exempt from OASDI tax until the child turns 18. For domestic work in your private home, the exemption runs until age 21. If the business is a corporation, or a partnership that includes anyone other than both parents, the exemption does not apply and the child’s wages are subject to full FICA taxes regardless of age.15Internal Revenue Service.

What You Give Up
The religious exemptions on Forms 4029 and 4361 are the two routes that a U.S. citizen can actively apply for, and both are irrevocable once granted. You cannot change your mind later and buy your way back into Social Security to earn credits.3Internal Revenue Service. Form 4029, Application for Exemption From Social Security and Medicare Taxes and Waiver of Benefits6Internal Revenue Service. Form 4361, Application for Exemption From Self-Employment Tax for Use by Ministers, Members of Religious Orders and Christian Science Practitioners The Form 4029 exemption also waives Medicare, so approved members pay their own medical costs without the coverage most Americans rely on in retirement. This is not a tax-planning move; it is a religious decision with financial consequences that last for life.
Things That Look Like Opting Out but Are Not
If you worked for two or more employers in 2026 and your combined wages exceeded the $184,500 wage base, each employer may have withheld the full 6.2% independently, so more OASDI tax came out of your paychecks than you actually owed. You can claim the overpayment as a credit on your Form 1040.16Internal Revenue Service. Topic No. 608, Excess Social Security and RRTA Tax Withheld This is not an exemption. It is a refund of tax you already paid twice.
There is also a small threshold for household employees. If you hire someone to work in your home, OASDI applies once you pay that worker $3,000 or more in cash wages during 2026; below that, neither side owes Social Security or Medicare tax on the wages.17Internal Revenue Service. Publication 926 (2026), Household Employer’s Tax Guide Cross the line and the full obligation applies.
If You Stop Paying Without Qualifying
The IRS treats unpaid payroll taxes as trust-fund money and pursues them aggressively. Employers who miss deposits face failure-to-deposit penalties that start at 2% for deposits one to five days late and climb to 15% after the IRS demands payment, with interest accruing on top.18Internal Revenue Service. Failure to Deposit Penalty If the IRS finds the underpayment was fraudulent, such as deliberately misclassifying employees as contractors to avoid payroll taxes, the penalty is 75% of the underpaid amount, and the taxpayer has to prove which portion was not fraudulent.19Office of the Law Revision Counsel. 26 U.S. Code 6663 – Imposition of Fraud Penalty For a self-employed worker, simply omitting the tax from a return produces the same result: back taxes, penalties, interest, and, at the far end, fraud exposure. There is no informal way to opt out.
