No, salaries are based a pre-tax basis. In other words you’re told you’ll make $120,000 per year, that amount is before taxes.
But companies also pay taxes before even paying you. So they’ll pay 140k to pay you 120k which you’ll earn 100k (along those lines)
They pay tax after paying you.
Payroll is an expense that gets deducted from revenue before calculating taxes.
They pay employer contributions/insurance/deductions but you pay the tax on it. It’s to avoid double taxing that money (corp pays tax and you pay tax).
Edit for replies: yes, they pay payroll tax but that is based on payroll, and is a percentage of payroll. The other replies were referring to bottom line tax and revenue/profit. Maybe I should have been clearer but I was trying to keep it easy and not muddy the waters.
