    Rendition Penalty

    For business personal property tax accounts, the law requires that a 10 percent rendition penalty be assessed and collected where the owner fails to render values on a timely basis. 

    If you have any questions about this penalty, please contact the Tarrant Appraisal District  (TAD) at 817-284-0024.

    TAD is also responsible for questions concerning value, owner name, owner address or exemptions.

    Additional Collection Penalty

    On February 1, current year taxes become delinquent and will incur penalty and interest according to the schedule below unless the first half payment was paid by the November 30 due date. 

    An additional collection penalty may be charged on accounts that are delinquent on April 1 for personal property or July 1 for real property.  Mineral accounts are considered real property. 

    The collection penalty will be 15 percent or 20 percent of the total taxes, penalties and interest due, depending on your taxing jurisdiction. 

    After July, interest continues to accrue at 1 percent per month. 

    Taxes not paid by January 31 will increase as follows:
