Eligibility to opt out of Social Security is narrow and set by federal statute. You may qualify only if you fall into one of a few specific categories: members of certain long-established religious sects that oppose insurance, ordained ministers and Christian Science practitioners who object on religious grounds, foreign students and scholars on specific nonimmigrant visas, some state and local government employees whose employers provide a qualifying pension instead, students working for the school they attend, and workers whose situations are governed by an international totalization agreement. Everyone else pays in, with no form, election, or legal argument that changes that.
The Default Rule for Almost Every Worker
If you earn wages, your employer withholds 6.2% for Social Security and 1.45% for Medicare, and matches those amounts. For 2026, the Social Security portion applies to the first $184,500 of earnings. Self-employed workers pay both sides, a combined 15.3%, and can deduct the employer-equivalent half when calculating adjusted gross income.1Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
There is no general checkbox, waiver, or procedure for stepping out of the system. The exemptions below are the entire list, and each one has strict eligibility rules the IRS and Social Security Administration enforce.
Members of Qualifying Religious Sects
Members of recognized religious sects that oppose all forms of public and private insurance can apply for a full exemption from both Social Security and Medicare taxes. The Amish and Old Order Mennonites are the groups most commonly associated with this provision, though other sects may qualify.2Social Security Administration. Are Members of Religious Groups Exempt From Paying Social Security Taxes?
To qualify, you must be conscientiously opposed to accepting benefits from any public or private insurance system covering death, disability, retirement, or medical care. Your religious group must have existed continuously since at least December 31, 1950, and must make reasonable provision for its dependent members. And you must never have received or been entitled to any Social Security or Medicare benefits.
You apply on Form 4029, which goes to the Social Security Administration’s Religious Exemption Unit rather than directly to the IRS. Both agencies must jointly approve it.3Internal Revenue Service. Form 4029 – Application for Exemption From Social Security and Medicare Taxes and Waiver of Benefits You still need a Social Security number to file. Since 2004, SSA has returned any application without one. If you have a religious objection to holding an SSN, you can request that a number be assigned solely for Form 4029 processing and ask that no card be issued.4Social Security Administration. POMS RM 10225.035 – SSNs for the Amish and Mennonites (and Other Religious Exempt Communities)
The exemption lasts as long as you remain a member and continue following the group’s teachings. If you leave or stop meeting the requirements, you must notify the IRS within 60 days. The waiver of benefits is irrevocable for the period it was in effect: you cannot go back and claim credit for those earnings later.
Ministers, Religious Order Members, and Christian Science Practitioners
Ordained, commissioned, or licensed ministers, members of religious orders who have not taken a vow of poverty, and Christian Science practitioners can apply to exempt their ministerial earnings from self-employment tax. The statutory basis is 26 U.S.C. ยง 1402(e), which requires you to certify that you are conscientiously opposed to accepting public insurance benefits on religious grounds.5Office of the Law Revision Counsel. 26 USC 1402 – Definitions
This exemption works differently from the Form 4029 version in three ways that matter. It covers only ministerial earnings, so any secular side income remains fully taxable.6Internal Revenue Service. Form 4361 You must inform the church or religious order that ordained you that you oppose public insurance. And once the IRS approves your Form 4361, the decision is permanent. You can never reverse it.
The filing deadline is tight. Form 4361 is due by the due date (including extensions) of your tax return for the second year in which you had at least $400 of net self-employment earnings from ministerial services. Miss that window and the option is gone.7Internal Revenue Service.

Nonresident Aliens on Certain Visas
Foreign students, scholars, researchers, professors, and trainees temporarily in the United States on F-1, J-1, M-1, or Q-1 visas are exempt from Social Security and Medicare taxes on wages earned while they hold nonresident alien status. The work must be authorized by U.S. Citizenship and Immigration Services and must connect to the purpose for which the visa was issued.8Internal Revenue Service. Aliens Employed in the U.S. – Social Security Taxes
The exemption ends in several situations. Foreign students on F-1, J-1, or M-1 visas who have been in the U.S. for five or more calendar years generally become resident aliens under the tax code and lose it. It also does not extend to spouses and children on F-2, J-2, or M-2 dependent status, or to employment outside the scope of the original visa.9Internal Revenue Service.

State and Local Government Employees With a Qualifying Pension
Not every state or local government employee is covered by Social Security. Federal law lets a public employer exclude workers if they participate in a retirement system that provides benefits at least as generous as Social Security would.10Social Security Administration. How State and Local Government Employees Are Covered by Social Security and Medicare
This is not something you elect as an individual. The decision belongs to the government employer and depends on whether it has a qualifying pension plan or a voluntary coverage agreement under Section 218 of the Social Security Act. If neither exists, Social Security coverage has been mandatory since July 1991 under the Omnibus Budget Reconciliation Act of 1990.11Social Security Administration. Pensions for State and Local Government Workers Not Covered by Social Security – Do Benefits Meet Federal Standards?
Students Working for Their School
If you are enrolled at a school, college, or university and you work for that same institution, your wages are generally exempt from Social Security and Medicare taxes. There is no form to file. Your employer simply does not withhold FICA.12Internal Revenue Service. Student Exception to FICA Tax
The condition is that the employment has to be incidental to your education, not the reverse. Working full-time for the school while taking a single evening class likely will not qualify. And if you work for an outside employer, even one physically located on campus, the exemption does not apply.
Workers Covered by an International Totalization Agreement
The United States has bilateral Social Security agreements, called totalization agreements, with roughly 30 countries. They exist to prevent workers from paying into two systems at once.13Social Security Administration. Totalization Agreements
The basic rule: if your employer sends you to an agreement country for five years or less, you stay in the U.S. system and are exempt from that country’s social security taxes. If the assignment runs longer than five years, you switch to the foreign country’s system and stop paying U.S. Social Security taxes. Self-employed workers follow parallel rules based on where they would normally owe.
To document that you belong to a foreign system and are exempt from U.S. FICA, you obtain a Certificate of Coverage from the foreign country’s social security agency and present it to your U.S. employer.14Internal Revenue Service. Totalization Agreements
What You Give Up by Opting Out
Every exemption comes with a matching loss of benefits. You do not keep the tax savings and still collect retirement, disability, or survivor benefits later. The trade-off is absolute for the earnings the exemption covers.
Social Security retirement benefits require at least 40 work credits, roughly ten years of covered employment. If your exempt years leave you short, you will not qualify for a retirement benefit at all. Disability insurance has its own recent-work-credit requirements that vary by age. Ministers with an approved Form 4361 are the mildest case: because the exemption only strips out ministerial earnings, any secular job still builds credits, and a minister who works enough covered years can qualify on that record.15Social Security Administration. POMS RM 04907.001 – Processing IRS Form 4361
For Form 4029 filers, the waiver reaches spousal and survivor benefits that would otherwise be paid on the exempt worker’s record. SSA policy does allow benefits to a spouse or surviving spouse who has their own approved exemption, minimal or no earnings on their own record, and a cessation event such as leaving the religious group.16Social Security Administration. POMS GN 01802.274 – Filing Dates, Effective Dates and Termination of Exemption
Medicare is where the cost hits hardest. Form 4029 filers waive rights under both Title II and Title XVIII of the Social Security Act, which means no premium-free Medicare Part A at 65.3Internal Revenue Service. Form 4029 – Application for Exemption From Social Security and Medicare Taxes and Waiver of Benefits If the exemption later ends and you want Medicare but lack enough credits, you have to buy into Part A. For 2026, that costs $565 per month with fewer than 30 quarters of coverage, or $311 per month with 30 to 39 quarters.17Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
What Happens If You Try to Opt Out Without Qualifying
Every few years, a tax scheme circulates online claiming that ordinary workers can escape Social Security by filing certain forms or making constitutional arguments. The IRS has explicitly identified the claim that wages are excluded from Social Security taxes if you waive the right to benefits as a frivolous position.18Internal Revenue Service. Notice 2008-14 – Frivolous Positions
The penalties stack. There is a $5,000 frivolous return penalty for filing a return based on a position the IRS has identified as frivolous. There is an accuracy-related penalty of 20% of the underpayment if the IRS finds negligence or disregard of the rules. The Tax Court can impose up to $25,000 for bringing a frivolous case.19Internal Revenue Service. The Truth About Frivolous Tax Arguments – Section III Willfully filing false information to avoid withholding can bring criminal charges: up to one year in prison and a $100,000 fine, rising to five years and $250,000 if the case is charged as tax evasion.
No court has accepted the argument that an individual worker can unilaterally opt out of Social Security. If a promoter is selling that strategy, they are selling a penalty.
