“I did not have to pay taxes last year” and “It did not affect the amount of taxes
I paid” doesn’t fully describe your details. To be safe, you should file an
amended return for 2016. Even when no tax is owed, some of you capital loss
carry forward will be “consumed” on each year’s return. To accurately calculate
the carry forward to 2017, you should prepare an amended return (even if you don’t
actually file it) or consult a tax pro
to accurately calculate the carry forward and determine if you must amend.
