Get your taxes done using TurboTax

I appreciate all the great advice here, but I am reading that if you have W4 wage income or IRA distributions, you are allowed to have tax year liability withheld from those sources in a single payment as late as Dec 31 and it's deemed as though it was spread out over the year (Ref IRC Section 6654(g)(1)).

 

I have found this information on several  tax planning websites and they all agree.
