INS/MED usually indicates an employee contribution towards medical cover. It is different from Medicare payroll tax. Family coverage, arrears and mid-period changes can make the deduction differ from an earlier statement.

How to read this entry

Use the meaning Medical insurance deduction alongside the column heading. An earnings amount, an employee deduction and an employer-cost memo can have different effects even when their labels look similar.

Example on a pay statement

A $180 monthly employee premium split between two semimonthly checks is $90 per check. A catch-up deduction may temporarily increase this amount after late enrolment.

Examples illustrate the checking method. They are not a personal tax calculation or a promise of a particular benefit.

What to check with payroll

Compare the coverage tier, effective date and employer premium schedule with the current and YTD deductions.
