Okay, this table from the BEA seems to be their source. (1102.5 ÷ 12026 ≅ 9.2%) This document from the BEA defines "Personal Current Taxes" as:

Quote:
[T]axes that are paid by households [including] Federal and state income taxes and state and local taxes on property other than homes, motor vehicle license payments, and other personal license payments. State and local prop­erty taxes on homes are excluded from this measure because they are treated as taxes on production.

It does exclude some taxes, but it still seems quite wrong to me.
