With respect to the first quarter of calendar year 2011, each employer shall pay a surcharge equal to 0.5% of the total wages for insured work subject to the payment of contributions under Sections 234, 235, and 245. The surcharge established by this Section shall be due at the same time as contributions with respect to the first quarter of calendar year 2011 are due, as provided in Section 1400. Notwithstanding any other provision to the contrary, with respect to an employer whose contribution rate with respect to the first quarter of calendar year 2011, calculated without regard to this amendatory Act of the 97th General Assembly, would have exceeded 5.4% but for the 5.4% rate ceiling imposed pursuant to subsection A of Section 1506.3, the amount due from the employer with respect to that quarter and attributable to the surcharge established pursuant to this Section shall equal the amount, if any, by which the amount due and attributable to the 5.4% rate exceeds the amount that would have been due and attributable to the employer's rate determined pursuant to Sections 1500 and 1506.1. Payments received by the Department with respect to the first quarter of calendar year 2011 shall, to the extent they are insufficient to pay the total amount due under the Act with respect to the quarter, be first applied to satisfy the amount due with respect to that quarter and attributable to the surcharge established pursuant to this Section. All provisions of this Act applicable to the collection or refund of any contribution due under this Act shall be applicable to the collection or refund of amounts due pursuant to this Section. Interest shall accrue with respect to amounts due pursuant to this Section to the same extent and under the same terms and conditions as provided by Section 1401 with respect to contributions. The changes made to Section 235 by this amendatory Act of the 97th General Assembly are intended to offset the loss of revenue to the State's account in the unemployment trust fund with respect to the first quarter of calendar year 2011 as a result of this Section 1506.5 and the changes made to Section 1506.3 by this amendatory Act of the 97th General Assembly.
