The legislative change adding the "Experience History Factor" into the tax rate calculation formula will apply to the 3rd and 4th Quarter rate for 2016. Rates for these two quarters will be recalculated in November 2016, and your account will be properly credited if there is any amount over paid for the 3rd Quarter. You can request a refund or apply it as a credit to future quarters. The changes set forth in HB 283 do not have an impact on 2016 Quarter 1 or Quarter 2 payments.
