Social Security has rules about how much money you can earn while receiving benefits. These limits change each year and work differently depending on whether you're receiving SSDI, SSI, or both. Understanding Substantial Gainful Activity (SGA)—the income threshold Social Security uses to measure work—helps you know when your benefits might be affected or when you need to report earnings to Social Security.
The articles here explain how Social Security counts your income, what the current year's earnings limits are, how work incentives can let you earn more without losing benefits, and what happens when your income crosses these thresholds. You'll also learn how to report earnings correctly and what to do if your benefits change because of work.
