If you know your tax rate... it should be adding 1/3 of the amount you withdrew to your taxable income and applying the tax accordingly. You can ball park it and see if it's close, or double... I have to do this tonight I haven't tried yet. i.e. you took out 10,000 and your in the 24% bracket, you would owe 2400, spread over three years it SHOULD be 800 each year... You can pay more, or re deposit some or all of the borrowed amount back in your acount to reduce it. Anyway that's my understanding and good enough for a sanity check. but not tax advice!
