@tpuckett - comes April 15th, the tax is the same.
your employer is required to use different withholding tables for base salary vs. commissions, but that will all settle up on April 15.
do not confuse 'withholdings' with 'tax liability'. Tax liability is the tax you owe the IRS (and State) and is calculated on your tax return. Withholdings 'pay down' the tax you owe owe against that tax liability and will result in either a refund or additional payment due.
