-7- Because petitioners failed to prove they reasonably relied on a competent tax professional, and because they failed to assert any other basis for relief, we hold that petitioners failed to prove that they had reasonable cause within the meaning of section 6664(c). Therefore, we find petitioners are liable for accuracy-related penalties under section 6662(a) for the years at issue. In reaching our holdings, we have considered all arguments made, and, to the extent not mentioned, we conclude that they are moot, irrelevant, or without merit. To reflect the foregoing, Decision will be entered under Rule 155 in docket No. 24184-05. Decisions will be entered for petitioners in docket Nos. 24183-05 and 24185-05.Page: Previous 1 2 3 4 5 6 7Last modified: November 10, 2007
