I did think the letter sounded ok for the most part, Val... although the bit about "not sure how to be do the sharing" sounded a little... stand offish...
OTOH, take note in what 25 said re: a pro...
I seem to be fine, but apparently my W is being audited from last year's filing... according to her, the audit request sounded more like an accusation of fraud... yikes!
I appear to be all good on that end... no nasty letters from revenue services...
Anyhow, the "splitting" year might be best handled by a real pro... take the loses where ever they may be for the year and the filing...
