House Bill 5

House Bill 5 becomes law!

Ohio’s municipal income tax system has long been an area of frustration and burden for Ohio's business community. House Bill 5, signed into law Dec. 19, 2014, is a great example of CPA leadership in action and demonstrates the power of a strong and unified voice for the profession.

Gov. Kasich signs House Bill 5 into law on Dec. 19, 2014 surrounded by OSCPA staff and other supporters.

OSCPA led these efforts, working with the Municipal Tax Reform Coalition, a partnership of 30+ organizations in Ohio driving reform of Ohio’s municipal income tax code. Together, they represent a large share of the business and individual taxpayers who are the lifeblood of Ohio’s economy.

Since 2014, OSCPA has continued to work for additional fixes to the most complicated municipal tax structure in the nation.
