Take-Home Pay
(After Tax) · 2022 estimate
Of the $140,365 Mark Cossarin earned in 2022, roughly $96,009 would remain after income tax, CPP and EI, an all-in deduction rate of about 31.6%. That is about 5% more than the $134,210 paid in 2021. Records under this name have appeared on the Sunshine List 16 years in all, first in 2007. Pension contributions — likely OTPP for teachers or OMERS in the School Boards sector — would typically trim another 7–10% off that figure.
