Taxes become delinquent on the day after the listed due date on your tax bill. Delinquent taxes incur a penalty of 2 percent of the delinquent amount and incur interest continually at the annualized rate of 10 percent. Missoula County has the authority to collect delinquent taxes in a number of ways, including through a Writ of Execution, certain types of liens and through public auction for personal property. Delinquent real property taxes are a lien upon the real property. Each August, Missoula County sells those liens to private parties. A taxpayer generally has three years from the date the tax lien was attached to pay the delinquent taxes or risk losing the real property. In some cases the period is only two years. We strongly encourage taxpayers to make every effort to pay their taxes to avoid the harsh results that can come from delinquent collection procedures.
