I am doing my 2011 taxes in the USA. How can I use the 2010 Capital loss Carryover figues in 2011?

The carry-over loss from 2010 is FIRST used to offset any capital gains realized in 2011.

Once that offset is done, if there is still a carry-over loss, you can claim up to $3,000 (if SINGLE or Married Filing Jointly or Head of Household) of the loss against OTHER income (wages, salary, interest, rental income, etc).

If, after claiming the $3,000, there remains a loss carry-over, the remaining amount is carried forward to 2012.

This is the process until the loss is used up, or until you die.

I have clients who had losses from the .com stock bust who, every year, claim $3,000 in losses on their tax returns from those losses in 2000. At that rate, they will either die or be VERY old (say 103) before they use them all up, if they do not get back into the stock market and try to earn some money.
