Experience Rating
PURPOSE: This rule prescribes conditions under which a calculated
experience tax rate is permissible, cut-off date for adjustments in
prior reports and conditions for accepting voluntary contributions.
This rule implements sections 288.090, 288.113 and 288.125,
RSMo. This rule was previously known as regulation no. 11.
(1) An employer shall be eligible for experience rating for a
calendar year in the event that—
(A) S/he was an employer on or before the first day of
the twelve (12)-month period immediately preceding the
calculation date for that year; and
(B) There was no period of eight (8) or more consecutive
calendar quarters, in the first eleven (11) of the last thirteen (13)
calendar quarters immediately preceding the calculation date
for that year, in which no wages for employment were paid by
that employer.
(2) A reasonable time after June 30 for a cut-off date for rate
calculation purposes is established as the period ending
with the date on which contribution and wage reports and
contributions for the second calendar quarter of any year
are delinquent as provided in section 288.090, RSMo. All
contributions received by the division by that date shall
be considered as contributions paid and credited within
the time required and those contributions shall be used in
the calculation of the employer’s contribution rate for the
following calendar year. Any adjustment of contributions or
wages in respect to periods prior to July 1 of any year which
are approved on or before the cut-off date shall be used in the
calculation of contribution rates for the succeeding calendar
years. All benefits paid prior to the July 1 calculation date shall
be charged against the employer’s account and used in the
calculation of contribution rates applicable to the succeeding
calendar year.
(3) Voluntary payments shall be transmitted by an employer
to the division with a signed written statement identifying
the amount as a voluntary payment. No voluntary payment
will be accepted from an employer who is not eligible for an
experience rating.
(4) A written determination showing contributions credited,
benefits charged and the contribution rate for a calendar year
shall be mailed to each employer as soon as practical after the
July 1 calculation date.
