Taxing Johnny Football

Sports Illustrated looks at the tax implications of Johnny Manziel going to Cleveland - instead of staying in Texas.
Manziel can still avoid Ohio's income tax on most of his endorsement earnings simply by making sure that he remains a Texas resident. He's thus likely to keep his Texas residency and not avail himself of Ohio tax law unless it's absolutely necessary. A local trading card show or endorsement for a Cleveland car dealer would trigger Ohio tax law, but national endorsement deals would not. Expect Manziel to avoid spending 182 days in Ohio, as doing so would risk him being classified as a "full-year nonresident" under Ohio law and having higher taxes.
Maybe the NFL draft should be a Tea Party.
