<<I just started investing because of the Motley Fool. Now I would like a simple short primer on the tax implications of these trades I a making. ie: how to keep track of the numbers, what to with them and when. Thanks>>

Well, there is really no one "simple, short" primer regarding tax and investing issues. But a few things that you might want to consider:

1. Check with your local bookstore (or cyber bookstore Amazon.com)in order to check out books on the subject. Other than a few primers on investing in general, and a section on taxes, I don't know of anything specifically that you'll find. You can certainly pick up a tax guide (written by Lasser, Andersen, H&R Block, etc.)and review a number of differenct tax issues (and simply focus on the investing issues), but that may be a little bit more than you really want.

2. Check out IRS Publications 17 and/or 550. Publication 17 is an overview of ALL tax issues. Pub 550 deals specifically with investment issues. Neither is short or particularily simple. And they will not reference the new tax law changes yet (check out Taxes Frequently Asked Questions for additional information on the new tax law), but you will get a basic foundation.

You can order the IRS Pubs by calling IRS at 1-800-TAX FORM, or you can visit the IRS web site by pointing your web browser to: http://www.irs.ustreas.gov

Hope this helps...
