# Appeal a property tax assessment

## When to use

Homeowners who think their assessed value is too high and want a clear checklist before the deadline. This is not legal or tax advice. Check dates and forms with your local assessor or board. Do not paste your parcel or account numbers into a chatbot.

## Steps

1. Find your assessment notice and write down the assessed value and the date the notice was issued. Deadlines are counted from local rules, so check the date with your local assessor or appeal board.
2. Look up who takes appeals where you live: your local assessor and an appeal board, which may be called a board of review or a board of equalization. This page cannot know your state.
3. Check the deadline with that office. As examples only, Washington's Department of Revenue says it is the later of July 1 of the assessment year or 30 days after the Change of Value Notice, with some counties allowing 60. Illinois tells owners to ask the county board of review for deadlines and forms, and says it is generally too late once you get the tax bill.
4. Pick your reason. As an example, Illinois lists four: the assessor's market value is higher than actual market value, the assessment ratio is higher than the local median, the assessment uses inaccurate facts such as a wrong measurement, or the assessment is higher than similar neighboring properties.
5. Gather evidence. Illinois lists the property record card, photos, records for similar nearby properties, your purchase documents, an appraisal, and recent comparable sales.
6. Ask the assessor to review it first. Washington says many disagreements settle at that level, but you still need to file on time to keep your appeal rights.
7. Ask the chat to draft the written appeal from your facts. File it on your area's official form. Washington says a letter or phone call is not accepted in place of the form.

## Prompt

Fill the [BRACKETED] parts with the user, then follow this prompt:

```
Help me prepare a property tax assessment appeal. This is not legal or tax advice. I will check every deadline and form with my local office.

I will not paste my parcel number, account numbers or SSN.

My state and county: [state, county]
Assessed value on my notice: [amount]
Date the notice was issued: [date]
Why I think it is too high: [reason]
My evidence: [comparable sales, purchase price and date, errors in the record, photos]

1. Make a checklist with the deadline questions I must confirm with my local office.
2. Sort my evidence into the four reasons: value above market, ratio above local median, wrong facts, higher than similar neighbors.
3. Draft a short written appeal using only my facts.

Show me the checklist first. Do not guess deadlines, forms or my state's rules. Ask me. I file it myself.
```

## Guardrails

- Draft first and show the user. Never send, post, pay, book, cancel or delete without the user's explicit approval of that exact action.
- Use only facts the user gives you or that you can cite. If something is missing, ask instead of guessing.

## Common snags

- Waiting for the tax bill. Illinois says it is generally too late to appeal that year's assessment by then.
- Skipping the form. Washington says a letter or phone call is not a substitute for the appeal form.
- Assuming your state works like another. Deadlines, boards and forms differ by place, so confirm with your own office.
