Frequently Asked Questions

What is a Property Tax Audit?

Business Personal Property is subject to Audits by an Auditor-Appraiser from the County Assessor's Office. The Personal Property statements filed each year are audited for correctness, and if there are differences in the audit value from the assessed value, those changes are made to the property tax assessments for the person or entity audited.  The audit may result in an increase  or decrease in property taxes.  When there are increases a revised tax bill is the result, when there is a decrease a refund of excess property taxes paid may be made to the taxpayer.
