Get your taxes done using TurboTax

...exactly......let the software do the calculation, since there's a lot of "stuff" remaining to be accounted for.

 

BUT #`1...if you are playing with the Notice 703 on your own, then yes, any excess investment losses not yet accounted for, up to 3000 max,  can be subtracted from line C.

 

But #2..but ..but, this assumes you have any unused excess losses remaining to subtract.  i.e., you may have investment gains this year that will be used first to offset any losses you had this year ( or carried over from last year ).....your losses need to be subtracted from those gains first.  Particularly for year-end Mutual Fund distributions, I have at least one that doesn't report long-term gain distributions until 2 days before the end of the year.  Those all figure into line C too, so any guesstimates you make on your own now, using Notice 703, are just that, just crude guesstimates.
