Get your taxes done using TurboTax

@TurboLover2 If your underpayment was less than $1000, you do not need the form. If the total tax you paid through estimated payments plus federal withholding for the year is at least 100% of last year's total tax or 90% of this year's total tax (line 63, Form 1040) then the form is not required to be filed.
