Carryover tax losses from year to year

[Ritzcracker]

how may years can a tax loss be carried forward, since you can only deduct $3,000 per year. What if you had a $50,000 loss?

[fanfare]

You may carry it forward indefinitely. be sure to print and keep for your records your Capital Loss carryforward worksheet each year.

Hopefully in some near future year you will have a $50,000 profit and then it will be used up immediately. 

[Critter]

You carry it until you use it up or die ... which ever comes first.

You must also enter the prior year carryover each year on your return even if you didn't have any cap gains to report.

If you are using Deluxe or higher version of the software or system, TurboTax will automatically insert the then-current carry-forward into your next year's tax return.  However, as said, by fanfare, you should, indeed must, make sure to download and save a PDF copy of your entire - complete with all worksheets - return.  That PDF may well be useful to you not only in the next year but possibly in a year beynd that.
