Social Security Tax Wage Base Jumps Nearly 9% for 2023

Many people don't realize that the Social Security tax that's withheld from each paycheck stops once your income exceeds a certain amount known as the "Social Security wage base." For instance, the Social Security wage base for 2022 is $147,000. So, if your income exceeds that amount this year, you don't pay the Social Security payroll tax on anything above $147,000. (Note: Social Security taxes are also known as Old-Age, Survivors, and Disability Insurance taxes, or OASDI taxes.)

This can be a significant tax cut for people earning more than the wage base. The tax rate for an employee's portion of the Social Security tax is 6.2%, so that's a pretty good savings for higher-income workers. (Your employer also pays 6.2% on any taxable wages, and you pay the full 12.4% if you're self-employed…although self-employed people can deduct part of that amount). For example, an employee with an annual salary $10,000 above the wage base saves $620, a worker with wages $30,000 over the base gets a $1,860 tax break, wages exceeding the base by $50,000 results in a $3,100 tax cut, and so on and so on. The more you make in excess of the wage base, the more money you save on Social Security taxes.

However, the Social Security wage base goes up each year that the national average wage index (opens in new tab) increases. When that happens – which is almost every year – more income is subject to the Social Security tax. Over the past five years, the wage base has gone up an average of $3,960 per year. But the wage base is going from $147,000 in 2022 to $160,200 in 2023. That's a year-over-year increase of $13,200 – the largest ever (just under a 9% increase) by a wide margin.

As a result, the maximum Social Security tax possible jumps from $9,114 to $9,932. So, for people making over $160,200 in 2023, they will be paying $818 more in Social Security taxes next year than they would have paid if the wage base remained at $147,000 ($573 more if the wage base grew at the average rate over the past five years). That's a significant increase by historical standards.

Of course, people earning under $160,200 in 2023 will have to pay Social Security taxes on all of their wages. Plus, if you make between $147,000 and $160,200 in 2023, you may be paying Social Security taxes on all your income for the first time (or the first time in a while).

Exemptions From Social Security Taxes

Some people aren't required to pay Social Security taxes. For instance, exemptions from Social Security taxes may be available if certain requirements are met for:

• Ministers and church employees;
• Members of certain religious groups (e.g., the Amish and Mennonites) who waive their rights to all Social Security benefits;
• Students employed by their school;
• Foreign students temporarily in the U.S. under certain types of visas;
• Minors employed in a family business;
• Non-citizens working for a foreign government in the U.S.; and
• Self-employed people with less than $400 of self-employment income.

Other exemptions may also apply.

Other Taxes Withheld From Your Paycheck

Take a look at your most recent pay stub. You'll notice that there are other taxes withheld from your paycheck other than the Social Security tax. For example, federal income tax is withheld from your pay, because Uncle Sam like to get his cut a little bit at a time (the amount is based on what you reported to your employer on Form W-4). State income taxes will also be withheld, unless you live in a state without an income tax.

You also have a Medicare tax taken out of your wages. This tax is equal to 1.45% of your pay. Unlike the Social Security tax, there is no cap on wages to which the Medicare tax applies. So, even if you earn more than $160,200 in 2023, you'll pay the 1.45% Medicare tax on all your wages. In fact, if you make too much money, you have to pay even more in Medicare taxes. That's because workers must also pay an additional 0.9% Medicare surtax on wages (and self-employment income) over $200,000 for singles and $250,000 for married couples filing a joint tax return ($125,000 for a married person filing a separate return).

(Note: Together, Social Security taxes and Medicare taxes are also known as Federal Insurance Contributions Act taxes, or FICA taxes.)
