Yes, you do. Whenever you work in a job that is covered by Social Security, your employer must deduct your Social Security and Medicare taxes from your salary and must pay the equal employer's share of the taxes. This is true, regardless of your age. Your earnings will be reported to SSA every year just like any other worker's earnings.
If you are self-employed while getting benefits and your net profit from your business is more than $400, that, too, is covered by Social Security and Medicare. You must report those earnings and pay the Social Security and Medicare taxes when you file your personal income tax return for the year.
Earnings after retirement may help increase the amount of your benefits. Each year we review the records for all Social Security recipients who work. If your latest year of earnings turns out to be one of your highest years, we refigure your benefit and pay you any increase due.
