Tax appeals
Assessed Value vs. Market Value
The value used for taxation can differ from a market-value opinion. A difference alone does not prove an error or establish grounds for an appeal.

Start by identifying each figure on your notice and the date it describes. Ask the assessor to explain the calculation before comparing it with a sale price or estimate.
Read the labels carefully
Your notice may distinguish estimated market value, assessed value and taxable value. Ratios, exemptions, caps and other local rules can affect how those figures relate. Do not apply another state’s ratio to your property.
Compare like with like
Use the relevant valuation date and property interest. A current listing price, a neighbor’s taxable value and a historical appraisal may answer different questions. Check recorded property characteristics before drawing a conclusion.
Investigate a possible error
Gather the notice, property record and documents that support your concern. Ask which correction or appeal process fits the issue and what evidence it accepts. An appraisal may help with a valuation question but is not always required.
Estimate savings cautiously
A change in assessed value does not translate into a universal savings formula. Ask how rates, exemptions and other components affect the tax year at issue. Future bills may change independently of an appeal outcome.
Questions people ask
Does a lower neighbor assessment prove mine is wrong?
No. Compare the relevant value, property facts and applicable rules. Ask whether an equity or valuation argument is available in your jurisdiction.
What evidence should I use?
Follow the reviewing authority’s instructions. Dated property records, relevant sales or an appraisal may be useful depending on the issue; none guarantees acceptance.
