I was single in 2016 and had a large unused loss carry forward. I married in 2017. Do I enter this amount on Form 1040, Line 21 as in the past? Utilization of the LCF will result in a negative AGI for us when filing jointly.
You will keep the Long-Term Capital loss carryforward from when you were single and carry it the joint return.
It does not, however, go on line 21.
You need to go to income area,
then to investments
right after the stock, Mutual Funds, Bonds, Other you will see Capital Loss Carryover.
You will enter the Capital Loss carryover from the 2016 return as a positive number and then
It will be applied against other gains and your loss used up each year if no other gains are limited to $3,000 per year.
