Interest on payments after the due date is 1.5 percent per month
on unpaid taxes. Interest is not calculated on accrued interest,
penalties or legal costs - only on tax due. Interest is assessed if the
payment is even one day late.
If all money owed or reports required are not received
by the Employment Department prior to September 1, of each year, an additional penalty of 1 percent of the previous year’s taxable payroll will be assessed.
Funds received from an employer apply first to legal
costs (including the service of warrants incurred in collecting the
debt), then to penalties assessed, then to interest assessed, and lastly
to unpaid tax assessed.
