January is a useful time to compare a new paystub with the final full paycheck of the prior year. A change in net pay should be traced before the budget absorbs it.
Separate gross from net
A raise can be offset by higher benefit premiums, retirement contributions, or withholding.
Check year-to-date resets
Annual counters return to zero, while some wage bases and deductions follow their own limits.
Fix errors early
An incorrect election or withholding amount becomes harder to unwind after many pay periods.
