You can change Social Security tax withholding through your employer's payroll system, but not directly with Social Security itself
Social Security tax withholding — the 6.2% that comes out of your paycheck — is controlled by your employer, not by Social Security Administration. If you want to change how much is withheld, you work with your employer's payroll department or HR system, not with SSA. Many employers now let you make this change through an online employee portal, but the process and availability depend entirely on your employer's setup.
The confusion happens because Social Security tax is different from federal income tax withholding. You can adjust federal income tax withholding by filing Form W-4 with your employer, and that form can often be submitted online. Social Security tax withholding, by contrast, is calculated automatically based on your wages and your Social Security number — there is no form to file and no way to reduce it below the standard 6.2% rate unless you fall into a specific category.
Key Takeaways
- Social Security tax withholding is set by law at 6.2% of your gross wages and cannot be lowered unless you are a member of certain religious groups or work for a nonprofit that has a religious exemption.
- You cannot change Social Security withholding through the Social Security Administration website or by calling them — the change must happen through your employer.
- Some employers offer online payroll portals where you can update tax information, but this typically affects federal income tax withholding, not Social Security tax.
- If you believe you are being over-withheld or under-withheld on Social Security tax, contact your employer's payroll or HR department to review your W-4 and earnings record.
Why you cannot lower Social Security tax withholding
The 6.2% Social Security tax rate is set by federal law and applies to all wages up to an annual cap. For 2024, that cap is $168,600 — meaning once your wages reach that amount in a calendar year, no more Social Security tax is withheld for the rest of that year. This is different from Medicare tax, which has no wage cap and continues at 1.45% on all earnings.
Because the rate and cap are fixed by law, there is no mechanism to reduce your Social Security withholding the way you can reduce federal income tax withholding. The only exceptions are narrow: members of certain religious groups (primarily Amish and Mennonite communities) who have filed Form 4029 with the IRS, and employees of nonprofit organizations that have received a group exemption from Social Security tax. If neither applies to you, the 6.2% will be withheld on all wages below the annual cap.
How to check if your employer offers online payroll changes
Many employers use online payroll systems — such as ADP, Gusto, Workday, or their own internal portal — where employees can view pay stubs, update direct deposit, and change tax withholding. If your employer offers this, you typically log in with your employee credentials and look for a section labeled "Tax Withholding," "W-4," or "Payroll Settings."
If you have access to an online portal, you will usually see your current federal income tax withholding and can adjust it by updating your W-4 information. However, the Social Security tax line will show only the standard 6.2% rate with no option to change it — this is correct and expected. If you want to verify that the right amount is being withheld, you can check your pay stub to confirm the Social Security tax is 6.2% of your gross wages (up to the annual cap).
If your employer does not offer an online portal, or if you cannot find the payroll section, contact your HR or payroll department directly. They can tell you whether changes can be made online and walk you through the process.
What to do if you think your Social Security withholding is wrong
If you notice that Social Security tax is not being withheld, or if it stopped before you reached the annual wage cap, contact your employer's payroll department first. The most common reason for missing withholding is that your Social Security number was entered incorrectly in the payroll system, or that you have multiple jobs and your employer is not aware of your other income.
If you have multiple jobs in the same year, each employer withholds 6.2% on all your wages at that job, regardless of what you earn elsewhere. This can result in over-withholding if your combined wages exceed the annual cap. You cannot prevent this by changing withholding — instead, you claim a credit for the excess when you file your tax return. The IRS Form 1040 instructions explain how to calculate and claim this credit.
If your payroll department says the withholding is correct but you still believe there is an error, you can review your Social Security earnings record by creating an account at ssa.gov. Your earnings record shows what Social Security has recorded for each year of your work history. If the record is wrong, you can file a correction request with Social Security, though this process typically takes several weeks.
The difference between Social Security withholding and federal income tax withholding
Federal income tax withholding is flexible — you can adjust it up or down by changing your W-4 form, and you can do this as often as your life circumstances change. Social Security tax withholding is fixed by law and has no flexibility for most workers. This is why you may see an option to change one but not the other in your employer's payroll system.
If you are self-employed, you pay both the employee and employer portions of Social Security tax (12.4% total) through quarterly estimated tax payments or when you file your annual return. You cannot reduce this amount either, though you can deduct half of your self-employment tax when calculating your adjusted gross income.
What happens if you change jobs mid-year
When you start a new job, your new employer will begin withholding Social Security tax at 6.2% on all your wages at that job. If your combined wages from both jobs exceed the annual cap, you will over-pay Social Security tax for the year. This is not a permanent loss — you claim the excess as a credit on your tax return when you file.
To avoid confusion, make sure your new employer has your correct Social Security number and that you have completed a new W-4 form (which affects federal income tax withholding, not Social Security tax). Some employers ask for this during onboarding; others require you to submit it through their payroll portal.
Frequently Asked Questions
Can I stop Social Security tax from being withheld from my paycheck?
No, unless you are a member of a may have access to religious group or work for a nonprofit with a group exemption. For all other workers, the 6.2% withholding is required by law and cannot be stopped or reduced. If you believe you should not be paying Social Security tax, contact your employer's payroll department or the IRS to discuss your specific situation.
Is there a Social Security website where I can change my withholding?
No. Social Security Administration does not manage tax withholding — your employer does. You cannot make changes through ssa.gov. Log into your employer's payroll portal if one is available, or contact your HR or payroll department to request a change to your W-4 or other tax information.
What if I owe Social Security tax because I did not have enough withheld?
This is rare, because Social Security tax is withheld automatically at a fixed rate. If it happened, you would owe the amount when you file your tax return. To prevent this in future years, make sure your employer has your correct Social Security number and that you report all jobs to each employer so they understand your total income.
Can I change my Social Security withholding if I have two jobs?
No, but you can adjust your federal income tax withholding on your W-4 to account for multiple jobs. Social Security tax will be withheld at 6.2% by each employer on all wages at that job. If your combined income exceeds the annual cap, you will over-pay Social Security tax and can claim the excess as a credit when you file your return.
