Big Misconceptions about Small Business and Taxes, by Chye-Ching Huang and James R. Horney, CBPP: Supporters of various tax benefits for high-income households often claim that failure to maintain them would have an undue effect on many small businesses.  ... 

This paper analyzes these claims.  It likely overestimates the number of small businesses adversely affected by changes to the top two marginal tax rates, the estate tax, and loopholes available to hedge-fund managers because it: (1) adopts an extremely generous definition of “small business” ... and (2) does not consider many valuable tax breaks that small businesses and small-business owners enjoy...  Yet it still finds that the claims typically made about small businesses and taxes are highly exaggerated, misleading, or false.
