> If your capital losses exceed your capital gains, the amount of the excess loss that you can claim on line 13 of Form 1040 to lower your income is the lesser of $3,000, ($1,500 if you are married filing separately) or your total net loss shown on line 16 of the Form 1040, Schedule D (PDF), Capital Gains and Losses. If your net capital loss is more than this limit, you can carry the loss forward to later years.

The losses that people like Donald Trump can carry forward are not capital losses, which is what we are talking about in this thread, and which apply to the situation pcardh0 described in his comment.

If your net capital loss is more than this limit, you can carry the loss forward to later years. You may use the Capital Loss Carryover Worksheet found in Publication 550, Investment Income and Expenses, or in the Form 1040, Schedule D Instructions (PDF), to figure the amount you can carry forward.

The 3000 is the deductible limit per year based on a loss, this isn't the limit to carry over.
