Home > Guides > Property tax appeals
File a written appeal with your local assessment office or review board before the deadline on your assessment notice: state your property details, the assessed value you dispute, the value you believe is correct, and your evidence, usually comparable recent sales of similar homes. Deadlines are short and strict, often just weeks after the notice arrives.
This is general information, not legal advice.
Assessment appeal windows are short: often 30 to 45 days from the date on the assessment notice, and missing the window usually means waiting until the next assessment cycle, a full year away. The notice itself tells you where to file and by when; read it the day it arrives. Some jurisdictions offer an informal review first, a phone call or letter to the assessor's office, before the formal board appeal. Take the informal step when it exists: assessors correct clear errors without a hearing, and it costs you nothing.
| Include | Details |
|---|---|
| Property identification | Address and parcel or roll number from your assessment notice |
| The disputed value | The assessed value you are challenging, quoted from the notice |
| Your proposed value | The market value you believe is correct, with reasoning |
| Comparable sales | Recent sales of similar nearby homes, with addresses and sale prices |
| Property condition notes | Defects the assessor missed: dated systems, damage, anything lowering value |
| Your contact info | So the board can schedule you or request more evidence |
The core argument is about value, not taxes: you are telling the board your home is worth less than the assessment says, not that your tax bill feels too high. Comparable sales ("comps") are the standard evidence: recent sales of similar homes in your neighborhood, close in size, age, and condition. Three to five strong comps beat ten weak ones. Your own recent purchase price is powerful evidence if you bought within the last year or two. Photos of defects the assessor never saw, an outdated kitchen, a failing roof, help too.
One technical point that trips people up: many jurisdictions assess at a fraction of market value (an assessment ratio), so compare your assessment against the same fraction of the comps' sale prices, not the full prices. And check the property record card for errors first: wrong square footage, a phantom extra bathroom, or a misclassified lot can win the appeal on their own.
Most formal appeals end at a review board hearing, which is less intimidating than it sounds: you present your comps and evidence, the assessor presents theirs, and the board decides. Bring copies of everything for the board members, keep your presentation factual and brief, and stick to value. If the board rules against you, many jurisdictions allow a further appeal to a state board or tax court, with its own deadline. Win or lose, keep the decision letter: it sets the baseline for your next assessment.
Yes. Describe the appeal to your AI assistant, approve the exact quoted price, and it is printed and mailed to the assessment office or review board. Use the registered option (US Certified Mail or Canada Registered Mail) so you have dated proof of filing: with appeal windows measured in weeks, proof of when you filed can matter as much as what you filed. Mail it with days to spare, not hours.
