Taxes are due in full December 20th; however, if at least one-half is paid, a grace period extending to June 20th is granted for the second installment. If the 20th falls on a weekend or legal holiday payments will be accepted as current the next business day.

If the first half is not paid on or before December 20th a one-time late charge of 2% on that half will be assessed. Interest begins to accrue on a daily basis beginning January 1st and is calculated based on 1% per month. If the second half is not paid on or before June 20th a one-time late charge of 2% on that half will be assessed. Interest accrues daily at a rate of 1% per month beginning January 1st on unpaid balances. Unpaid taxes on personal property and manufactured homes will be sent to the Sheriff’s Office on a “Warrant of Distraint”. Additional costs will be incurred and payment in full will be required. Therefore it is very important that the December and June payments be made on time.
