What to say if they say no

Say this

“I understand. Who else can approve this: a supervisor, or the retention or billing team?”
“Can you note on my account that I asked today, and send me your answer in writing?”
“Thanks for checking. If we can't fix it, my next step is to [escalate / file a complaint / switch].”

Then do this

Escalate to the next level (appeals board or state tax tribunal) before the deadline.
Check your eligibility for homestead or senior exemptions, which are separate from appeals.
File a formal assessment appeal before the deadline (see the property tax appeal guide).
Check whether you qualify for a homestead or senior exemption, which is separate.
Ask the assessor's office why you were denied and whether you can appeal.

What evidence helps a property tax appeal?

Factual errors in your property record (like wrong square footage) and recent sales of similar homes are the usual evidence. Many offices will correct a record error if you send supporting documents such as plans, a survey or an appraisal sketch.

Should I pay a property tax appeal service?

You don't have to. Appealing yourself is free. Contingency services typically charge a share of first-year savings (one major service lists 25%–35%). Separately, check homestead or senior exemptions, which are different from appeals.
