Legislative leaders in California, big box stores, and Amazon have reached an agreement to delay internet  tax collection until September 2012. There is no word on whether Governor Jerry Brown will support the plan and no mention of whether the 7,000 distribution center jobs Amazon previously offered the state is part of the package.   Amazon did agree to  stop supporting a repeal referendum and will join other retailers in pushing Congress to enact an internet sales tax law applying to all 50 states and the District of Columbia.  In a landmark 1992 ruling governing collection of sales taxes by remote sellers (they were mail-order firms then), the U.S. Supreme practically begged Congress to resolve the mess by enacting national standards.  But Congress never acted,  and given how quickly legislation gets through Congress these days, that’s not likely to happen any time soon.   Nonetheless, Amazon promises to start collecting the tax in September 2012 if Congress fails to act. It will be interesting to see whether that really happens.
