How much taxes would be taken out of a 1000 lottery win in Wisconsin?

Gambling or lottery winnings are taxed like any other income.

How much you pay ultimately depends on your own tax situation and personal tax rate. That all depends on things like your other earnings (or losses), marital status, number of dependents, types of expenses and deductions, where you live, etc. The income is like any other "ordinary" income. The withholding (like from a payroll, as an estimate of the tax) required at the casino or lottery agent is normally a minimum of 20%, but can depend again on your situation too.
