We assist the public by:

- Researching property sales for taxpayers evaluating their assessments;
- Guiding taxpayers doing independent research;

What can’t the Tax Advisor Office do?
We cannot reduce your assessed value, lower your tax bill, or change your property characteristics. However, we can advise you on the procedures to accomplish a change; what information is relevant and where to find it; who to talk to and how to most effectively present your case.
