- OASDI taxes fund Social Security.
- OASDI taxes get paid by two parties — the employee and the employer. Employees pay 6.2% of their wages, and their employer pays another 6.2%.
- Self-employed people must pay both parts for a total of 12.4%.
- The more OASDI taxes you pay, the higher your Social Security retirement benefits and your family’s survivors benefits will be.
- Even if you receive Social Security benefits, you still must pay OASDI taxes on all of your earned income.
What Are OASDI Taxes?
Old-Age, Survivors and Disability Insurance (OASDI) taxes are payroll taxes that fund the federal Social Security program. Employers, employees and people who are self-employed must pay these taxes each month or each quarter.
All collected OASDI taxes go into one of two trust funds. One is for retirement benefits. The second goes toward disability benefits. Some funds are then redistributed to people who currently draw Social Security benefits. The rest is invested with the goal of growing the funds for future claimants.OASDI Tax Rates

OASDI taxes only apply to earnings up to a certain threshold. For the 2023 tax year, that threshold is $160,200. All income above this amount is not subject to OASDI taxes.
The OASDI taxes you pay over your working life play a significant role in your retirement income. Understanding how the program works is a key component of smart retirement planning.OASDI is the part of Federal Insurance Contributions Act (FICA) taxes that pay for Social Security. Eighty-five percent of each OASDI tax dollar goes to benefits to current retirees and their families and to surviving spouses and children of workers who have died. Calculating OASDI taxes for self-employed workers can be difficult. It might be helpful to consult with an accountant. Paying OASDI taxes can also be burdensome. Paying on a monthly or quarterly basis might make more sense than paying a large annual bill.
How OASDI Taxes Impact Retirement Benefits
The amount you pay in OASDI taxes during your working life directly affects the monthly payments you’ll get in retirement benefits. The more you pay into the fund, the more you’ll receive.
The Social Security Administration uses a complex formula to determine your Social Security benefit amount based on your past wages. You can get a rough idea of how much you’ll receive by putting your earnings history into SSA’s online calculator. Higher earnings result in a higher full retirement age benefit.
The maximum full retirement age Social Security benefit for 2023 is $3,627. To receive this much, you will need to have met or surpassed the OASDI tax threshold in all 35 of your highest-earning years.
OASDI Taxes and Self-Employment
Because they act as their own employer, people who are self-employed pay both parts of the OASDI tax. This makes their OASDI tax rate 12.4%.
To offset this higher tax burden, self-employed individuals can claim the employer portion of their OASDI taxes as a business expense. This significantly reduces their taxable income for the year.
Some self-employed people don’t have OASDI taxes automatically withheld from their paychecks as people who work for someone else do. If you’re self-employed and you don’t use a payroll service, you’ll need to set this money aside yourself and remit it to the IRS.
OASDI Taxes and Working in Retirement
The IRS levies OASDI taxes on all paid work regardless of the worker’s age or whether they claimed any Social Security benefits. This means you’ll still owe OASDI taxes on your earned income if you worked after you’ve started collecting Social Security.
However, OASDI taxes don’t apply to unearned income. You won’t have to pay taxes on your Social Security income, income from private pensions, income from investments, or any other sources of passive income used to fund your retirement.
OASDI Taxes and Estate Planning
OASDI taxes can also factor into estate planning. You won’t pay OASDI taxes on your estate, but the amount you pay during your working life affects how much your family could receive in the form of Social Security survivors benefits after your death.
Social Security survivors benefits go to spouses, ex-spouses, dependent parents, minor children and disabled children of workers who have passed away.Details of benefits payouts include:
- Your spouse could receive up to 100% of your full retirement benefit if they claim survivors benefits when they reach full retirement age.
- Your children receive 75% of your full benefit if they’re under 18 years old or are disabled.
- Your dependent parents each receive 75% of your full benefit if both are still living. If one parent is still living, their payment rate is 82.5%.
