Take-Home Pay
(After Tax) · 2025 estimate
Of the $171,993 Mark Koczij earned in 2025, roughly $115,989 would remain after income tax, CPP and EI, an all-in deduction rate of about 32.6%. That is about 1% below the 2025 median of $172,928 for Secondary School Principal on the Sunshine List. That is about 19% more than the $145,032 paid in 2024. Most School Boards employees belong to OTPP for teachers or OMERS, so actual take-home is likely another 7–10% lower after pension contributions.
