Some people are investing in their retirement without even realizing it.
If you have a traditional job, you pay 6.2% of your salary per year in Social Security taxes. That number is then matched by your employer.
But there's a cap on how much money people are expected to contribute every year.
In 2021, you will pay Social Security taxes on all of your income up to $142,800. That is a $5,100 increase from the 2020 wage-based cap.
