Frequently Asked Questions

Why should I protest my property taxes if I don’t know if I’m overpaying?

You should protest because you don’t know if you’re overpaying! Many homeowners don’t realize they have the right to protest, even if they are unsure if their home is overvalued. By protesting every year with TaxRanger.ai, you’ll know for sure.

What happens if I miss the protest deadline?

The deadline to file a protest is May 15, with no exceptions. If you miss filing, you must wait until the following year.

Does filing a protest really work?

Yes. There is no way to guarantee you will get a reduction from protesting, but you for sure won’t get one if you don’t try. Even small annual reductions compound over time, saving homeowners thousands over the years.

Can I protest if my home value didn’t increase?

Yes. If your property is unequally appraised compared to others, you may still qualify for a reduction.

Can the county increase my value if I protest?

No, the county cannot increase your value if you protest.
