Did you know?
When you check your paycheck deductions, you probably won't see a line for "Social Security taxes."
Instead, you may see a deduction for "OASDI," which is short for "Old Age, Survivors, and Disability Insurance." That's Social Security.
You may also see a separate deduction for Medicare. Social Security and Medicare together make up your FICA (Federal Insurance Contributions Act) deductions.
Some local and state government agencies, public schools, and companies located outside of the United States, for example, may not withhold Social Security taxes and may offer their employees a pension plan instead.
If you work or have worked for an employer that offers a pension plan instead of withholding Social Security taxes (called a noncovered pension), you should be aware of 2 provisions that could reduce Social Security payments.
