WAC 192-320-040
When will the department recalculate
employer tax rates? (RCW 50.29.080.) (1) The department may,
at its discretion, recalculate the tax rate for any employer
if it determines, within three years of the July 1 computation
date, that the rate as originally computed was erroneous.
(2) Except as provided in subsection (1) of this section,
an employer must submit a written request for rate review or
recalculation before the department will recalculate a rate.
This does not apply if the department determines that the
department's error caused an incorrect tax rate.
(3) The department will not recalculate a tax rate at the
request of the employer more than once in a calendar year.
