The money to fund Social Security doesn’t just come out of thin air. Rather, the program gets the bulk of its funding from payroll taxes.

As you work and earn money, you pay a portion of that into Social Security. If you pay enough Social Security tax in your lifetime, you’re then eligible for benefits once you get older.

But you won’t necessarily be taxed on your entire salary for Social Security purposes. Each year, the Social Security Administration (SSA) establishes a wage cap that determines how much income is taxed to fund future benefits.

In 2024, workers are required to pay Social Security taxes on earnings of up to $168,600. But in 2025, the Social Security wage cap is rising. And that means that higher earners will have to pony up even more.

Prepare to pay more if you earn a large salary

On October 10, the SSA announced a number of big Social Security changes, including a 2.5% cost-of-living adjustment and an increased earnings-test limit. The SSA also announced that 2025’s wage cap is rising to $176,100. This means that higher earners will have an additional $7,500 of wages subject to Social Security taxes.

But if you fall into that category, that doesn’t mean you’re handing an extra $7,500 over to the SSA. The Social Security tax rate is 12.4%, and if you work for an employer, you split that obligation evenly. So in reality, based on the new wage cap, you’re looking at paying an extra $465 into Social Security in 2025 compared to 2024, and so is your employer.

Meanwhile, your total Social Security tax bill maxes out at $21,836.40 for 2025. Of that, you’re on the hook for half if you’re a salaried employee, which means you’re paying $10,918.20.

Why it pays to take 2025’s Social Security wage cap in stride

You may not love the idea of having to pay more money into Social Security. But you should also know that some lawmakers have proposed raising the wage cap by far more than $7,500, or even eliminating it altogether so that earners pay into the program on all of their income, regardless of what that amounts to. In that context, having to fork over an additional $465 doesn’t sound so bad.

And even if you’re self-employed and don’t have an employer to split that tab with, you’re talking about an extra $930 in 2025 compared to the current year. With careful tax planning, you can find a way to make that work.

Remember, too, that while you may not love the idea of having to pay more into Social Security, it’s taxes like yours that are helping to keep the program alive so that when it’s your turn to collect benefits, they’ll be there for you. And also, the more you earn and pay into Social Security, the higher a monthly benefit you stand to receive in retirement.

This doesn’t mean that you’ll get every dollar you pay in Social Security taxes back in the form of benefits. But the formula used to calculate retirement benefits is based on lifetime earnings. So in a roundabout way, consider your higher Social Security tax bill in 2025 a contribution to your future financial wellbeing.
