Unlike the Senate measure, the tax hike would not be retroactive to Jan. 1 but instead would begin with the Saturday start of the budget year. That change, sought by Republicans, was designed to avoid having people pay even more in income taxes the rest of the year to catch up for the past six months. Also out is an expansion of sales taxes to some services. The tax hike would be permanent, against Rauner's desire to make it temporary to match a temporary property tax freeze he is seeking.
