Payment date vs. payment amount
Your payment date and your payment amount are different things. Your date usually follows the schedule rules; your amount can change for several reasons.
Common reasons
Deductions like Medicare premiums or changes in withholding can affect the net amount deposited.
SSA notices typically explain adjustments.
- Medicare premiums or adjustments
- Withholding changes
- Other administrative adjustments
What to do
If your amount changed unexpectedly, start by checking your SSA notice or your my Social Security account for a message.
