Capabilities

Tools 5

answer_property_tax_question

Use this for any general property tax question that is not about one specific address: "how do I appeal my property tax assessment", "does a deck raise property taxes", "does finishing a basement or a kitchen remodel increase property taxes", how assessments and exemptions work, what evidence wins an appeal. Applies to any US state. Returns sourced answers from Grove Hopper county and state guides and research posts, with links, and points the person to the free check for their own address. Optionally pass a state and county to prefer local guide answers. Do not use when the person gives an address and wants it checked (use check_property_tax_assessment). Read-only.

Discovered
calculate_property_tax

Use this when someone wants to estimate a property tax bill ("how much is my property tax"), see what a home improvement would add ("does a deck raise property taxes, and by how much"), or see what a successful appeal would save per year. Works for any US address, county or state. Give the assessed value from the tax bill or notice, or a street address and the assessed value is looked up. For the tax rate give any one of: the current annual tax bill, a rate in percent, a millage rate, or just the state and county (or an address) and the typical local effective rate is used and labeled as an estimate. Scenarios: estimate_bill, improvement (add improvementCost or addedAssessedValue), appeal (add newAssessedValue or reductionPercent). The formula and rate source are shown. Read-only.

Discovered
check_property_tax_assessment

Use this when someone asks "is my property tax too high", "is my home over-assessed", "what is my home assessed at", or wants to know if they can appeal the property tax assessment on a specific US address. Works for any US address. Takes a full street address, confirms the property and county, and returns the assessed value with its tax year and source link (read from the official county record where we connect to it directly, otherwise found by a live search of county and public record pages, and it says which), an estimated annual tax bill with the rate used, what a 10% lower value would save, the appeal deadline with days left, who hears the appeal and how to file, and a result card with a button to the free Grove Hopper report (comparable sales and assessments, strongest appeal angle, unclaimed exemptions). Can take up to about 25 seconds for addresses that need the live search. Do not use for general questions with no address (use answer_property_tax_question) or for non-US properties. Read-only; nothing is filed or submitted.

Discovered
find_property_tax_exemptions

Use this when someone asks about "property tax exemptions for seniors", veteran or disabled-veteran property tax exemptions, disability exemptions, a homestead exemption, or a senior property tax freeze. Works for any US state and county. Takes a state, optionally a county, and the situation (senior, veteran, disabled, homestead). Returns each program with what it does, who qualifies, how and by when to apply, and source links, from Grove Hopper county research, our 50-state roundups and a live search of official pages where needed. Do not use for appealing an assessment (use get_property_tax_appeal_deadline). Can take up to about 25 seconds when the live search is needed. Read-only.

Discovered
get_property_tax_appeal_deadline

Use this when someone asks for the "property tax appeal deadline", "when is the last day to appeal my property tax assessment", or where and how to file a property tax appeal. Works for any US address or county. Give a street address, or a county and state. Returns the exact deadline date with days left, the board or office that hears the appeal, the filing method, form and steps, and source links. Where a county sets deadlines per township or town (for example in Illinois, New York, New Jersey, Massachusetts and Michigan), a street address returns the date for that parcel's township or town. Where the deadline runs from the date on the assessment notice (for example in Texas, Florida, Georgia and Washington), it returns the rule and computes the exact day when given the notice date. Can take up to about 25 seconds for counties that need the live search. Do not use for exemption applications (use find_property_tax_exemptions). Read-only.
