For instance you make $1,000 in GOOG on Jan 10, 2005, then trade it, every day that year, up thru Dec 31st, 2005. You lost ..... $-35,000 net doing it.
Net loss is -$34,000 (+1000, -35000= -34,000). This is a wash sale, and the 34k loss is NOT allowable on THIS year's tax return, UNLESS you elected MTM in time for 2005.
It's a wash because it's a NET YEAR END loss....and you've traded it in the last 30 days.
Are you sure that's correct? There is a 30 day grace period, so if you DON"T trade GOOG in January of 2006 you can deduct all losses for 2005. If you trade GOOG before Jan 31 (let's say Jan20), the losses for 2005 will roll into to 2006 (ie you cannot take them in 2005) and used only to adjust the base cost of GOOG for the Jan20 trade.
So it's a simple issue to avoid. Just don't trade stocks you had total losses in in 2005 for the first 30 days of 2006.
