Take-Home Pay
(After Tax) · 2025 estimate

Of the $157,711 Jan Kowalczyk earned in 2025, roughly $108,129 would remain after income tax, CPP and EI, an all-in deduction rate of about 31.4%. It is up about 37% on the $115,419 paid in 2024. Records under this name have appeared on the Sunshine List 17 years in all, first in 2008. Pension contributions — likely PSPP or OPTrust in the Government of Ontario – Ministries sector — would typically trim another 7–10% off that figure.
