The taxes at the end of the year all even out. The tax withheld each check treats that check like it is your annual income.Amen!!!!
I double my income on OT yet pay double the rate of a base check. It feels like highway robbery!
So if you make 1000/week that would be an income rate of 52,000/year and its taxed as such.
If you get a bunch of OT and make $2000 in a week, it will be taxed as if you make 104,000 year.
At the end of the year, when you do your taxes though you will only pay the tax on annual income.
