ebo's misguided. i've been doing one ling accounting with robert green for 6 years. you think the irs wants to see 500,000 and $2 billion of sales. my 1099's reached 2800 pagfes before. one line is the most accurate accounting one earth. all you do is take your balance jan1st and take your balance dec 31st. so lets say your balance jan 1st in matd account is 50k and dec 31st its 70k so you made 20k. now add in all your withdrawels out of account lets say its 40k so now you have 20k plus 40k thats 60k. next subtract all interest and dividends so lets says thats 1k now you're at 59k. next add back margin interest which is deducted from account so thats another 500 so you're at $59,500. l;ets say your total sales are 1,000,000. that means your total cost is $940,500. so on sch d its total sales of $1,000,000 - total cost of $940,500 which equals a gain of $$59,500 on sch d. now its true the irs could ask for all your trades but highly douubtful so to be safe elect mark to market. man back int he 90's i'd spend 5 days doing my sch d and it wasn't near as accurate as thius. your total sales will alwsy be the same as the irs's. you work backwards on this from total sales on back so your sales are always the same as irs's. mtm aqccounting is not subject to the wash rule and its all one line accounting
