Most people expect Social Security to change only when they get an official letter, but the first clue is often smaller: a deposit that’s lower than last month. That’s because several common “triggers” can reduce benefits through withholding, offsets, or suspensions that show up in your payment before you connect the dots. The paperwork may exist, but it may come from a different agency, arrive as a separate notice you miss, or look like a routine Medicare update instead of a benefit change. The safest approach is knowing the biggest tripwires and doing quick monthly checks so you catch problems early. Here are six that deserve a spot on your radar.
