Underpayment/Late Fees
Pursuant to Wis. Stats. §§ 76.64 and 601.93 (2), insurers must make quarterly payments of their estimated premium taxes. If there is no amount due for a given quarter (such as due to a prior year overpayment), then no action is required.
If any insurer fails to make quarterly payments of at least one-fourth of the lesser of (a) the total premium tax for the previous calendar year OR (b) 80% of the actual tax for the current year, in the event of a deficiency the insurer shall be liable for interest in the amount of one and one-half percent of the amount due and unpaid for each month or part of a month that the amount is due.
Example: A company paid $10,000 in taxes incurred in the past calendar year and assumes that it will incur $15,000 in taxes in the current year in the State of Wisconsin. Under this assumption, the company must remit quarterly payments of no less than $2,500 each quarter to avoid additional interest. If the company will incur $8,000 in taxes (instead of $15,000), then each quarterly payment must be no less than $1,600 (one-fourth of 80% of $8,000) to avoid additional interest.
For negligent failure to file or pay, add $500 or 5% of amount due per month or fraction of a month during which the failure continues, up to 25% of the amount due, whichever is larger.
