The erroneous collection described in paragraph “b” does not continue for more than thirty days after the effective date of the rate change. 3. The relief from the obligation to collect sales or use taxes described in subsection 2 shall not apply if a seller fraudulently fails to collect tax at the new rate or if a seller has solicited purchasers on the basis of the rate in effect immediately prior to the rate change. 2003 Acts, 1st Ex, ch 2, §139, 205; 2010 Acts, ch 1145, §11, 17 Referred to in §99G.30A, 423.57, 423B.6, 423C.4
