Good day
Someone could help me to see how the tax is calculated wage because I have an agreement with my worker who will win an amount after taxes but I need to see the percentages of taxes, etcetc medicare for them is the amount

Thank you for attention to my own greetings

Can you explain this further. There are tax tables that are used to calculate withholding. If you are doing your own payroll, you should have a copy of those tables. If you have a service doing your payroll, then ask them.
