This checklist takes a homeowner or small commercial owner from the arrival of the assessment notice through the appeal, the exemption claim, and the delinquency process if it comes to that. The first phase is the calendar, because the appeal window is commonly thirty days and it is the only thing that cannot be recovered. Audit phases cover the property record card, the measurement, and the neighbors' assessments that are public record. Analysis phases build the adjusted comparables table and the sales ratio table that support the two independent grounds of appeal. Procedural phases work through the informal review, the local board hearing with a fifteen-minute script, the state tribunal, and the payment-under-protest rule that can dismiss an appeal. Exemption phases catalogue what to claim and how to claim it retroactively, including the tangled-title fix that restores eligibility. Delinquency phases set out the redemption deadline, the payment and deferral options, and the notice and surplus proceeds arguments available after a tax sale. A deadline table and fifteen ranked failure modes close the document.

Appealing a Property Tax Assessment and Claiming Exemptions: A Practical Checklist

Tax > Property Tax | Published 26 July 2024 - Updated 2 November 2025 | UpLaw - uplaw.us

If the assessment notice arrived recently, the deadline is probably about thirty days out. Do Phase 1 today. If taxes are already delinquent, go to Phase 10.

Use with Property Tax Assessment and Appeals: A Comprehensive Guide to Valuation, Exemptions, and Hearings and The Property Tax Appeal Toolkit.

Phase 1 — The calendar, today

☐ Find the appeal deadline on the notice. ⚠ Commonly ~30 days. Write it on a calendar in two places.

☐ Note the valuation date — commonly 1 January. ⭐ It fixes what evidence is relevant.

☐ Note the exemption application deadline, which is usually different.

☐ Ask the assessor's office three questions, today:

  • ☐ "Is there an informal review, and how do I request it?"
  • ☐ "Can the board increase my assessment on appeal?"
  • ☐ "Must I pay under protest to keep the appeal alive?"

☐ Photograph any condition problem now, and note whether it existed on the valuation date.

Phase 2 — The record card audit

☐ Obtain the property record card. It is a public record; most assessors post it online.

☐ Verify every line:

  • ☐ Gross living area ☐ Lot size ☐ Year built ☐ Style and stories
  • ☐ Bedrooms ☐ Full baths ☐ Half baths
  • ☐ Basement area and whether finished
  • ☐ Attic finish ☐ Garage: attached or detached, and size
  • ☐ Fireplaces ☐ Central air ☐ Porches, decks, patios
  • ☐ Outbuildings ☐ Pool ☐ Construction quality grade
  • ☐ Condition rating ☐ Effective age
  • ☐ Neighborhood code, and what else is in it
  • ☐ Sales history shown, and whether any transfer was non-arm's-length

☐ ⭐ Measure the house. Exterior measurement to the assessor's convention. Photograph the tape. A square-footage correction is the most common winning appeal in the country.

☐ Check the sketch against the actual footprint.

☐ Look for what does not exist — a demolished shed, an unbuilt addition, a permit pulled and never used.

Phase 3 — Build the comparables table

☐ Pull 3–5 comparables: same neighborhood code, similar size, age, style, condition; arm's-length sales within 12–24 months of the valuation date.

☐ ⚠ Exclude foreclosures, intrafamily transfers, estate liquidations, and post-renovation flips — unless you are arguing for inclusion and can say why.

☐ Adjust plainly, and state each amount: size · baths · basement finish · garage · condition · lot · location.

☐ Conclude with one number, and request it.

Subject A B C
Sale price —
Square feet
Size adjustment —
Baths / adjustment
Basement / adjustment
Garage / adjustment
Condition / adjustment
Adjusted value

Phase 4 — Build the uniformity table

⭐ The cheapest strong evidence in property tax practice, and it requires no expert.

☐ Pull the assessed values of comparable properties — public record. ☐ For those that sold recently, compute the ratio: assessed value ÷ sale price. ☐ Use at least five; ten is better. Use the median, not the mean. ☐ Compare the subject's ratio to the median. ☐ ⭐ If the jurisdiction publishes an equalization or sales ratio study, cite it — it is the assessor's own statement of the prevailing ratio. ☐ Ask whether a threshold deviation is required before relief is granted.

Property Sale price Sale date Assessed value Ratio
Median
Subject — —

☐ Authority: systematic disparity is a constitutional problem — Allegheny Pittsburgh Coal Co. v. County Commission of Webster County — subject to the limits of Nordlinger v. Hahn where the state has deliberately adopted an acquisition-value system.

Phase 5 — The exemptions

☐ Ask the assessor, in writing: "What exemptions am I eligible for, and can any be claimed retroactively?"

☐ Screen every one:

  • ☐ Homestead — owner-occupied primary residence. ⚠ Frequently must be applied for; not automatic on purchase
  • ☐ Senior exemption — age, sometimes income-tested
  • ☐ Senior assessment freeze — freezes the assessed value
  • ☐ Disability exemption
  • ☐ ⭐ Veteran exemption — enhanced or total at higher disability ratings; widely available and widely unclaimed
  • ☐ Surviving spouse — of a veteran or first responder
  • ☐ Agricultural, forestry, or conservation use valuation
  • ☐ Historic property abatement
  • ☐ Home improvement exemption — defers the increase from a renovation
  • ☐ Circuit breaker — relief keyed to tax as a share of income
  • ☐ Deferral — ⭐ converts an unpayable bill into a lien satisfied at sale

☐ ⚠ Exemptions lapse. Re-verify after a purchase, a refinance, a transfer into a trust or LLC, a marriage, a death, or a change in occupancy.

☐ Ask about portability — carrying a capped assessment to a new home.

☐ File the retroactive claim where the jurisdiction allows one to three years. ⭐ A veteran who never filed can sometimes recover several years with one form.

Phase 6 — Tangled title

⭐ A leading cause of lost exemptions and tax delinquency, and entirely fixable.

☐ The pattern: an owner died, the family stayed, no probate was opened, title remains in the decedent's name. ☐ The consequences: no homestead exemption · no access to repair grants or disaster aid · no sale or refinance · notices go to the decedent · drift into delinquency and a tax sale. ☐ The fixes: small-estate or summary probate · an affidavit of heirship where permitted · a determination of heirs · partition or buyout among heirs. ☐ ⭐ Legal aid does this work, and clearing title frequently restores several years of exemption eligibility at once.

Phase 7 — The informal review

☐ Request it immediately — it is free, fast, and where record-card errors get fixed in ten minutes.

☐ Bring: the corrected record card with errors circled · the measurement and photograph of the tape · photographs of condition problems · the comparables table · the ratio table.

☐ Ask the assessor directly: "What evidence would change this assessment?" Then supply it.

☐ ⚠ File the formal appeal before the deadline regardless of whether the informal review has concluded. The informal process does not extend the deadline.

Phase 8 — The board hearing

☐ File in writing by the deadline, with a specific requested value. ⚠ "It's too high" is not a request; "$286,000" is.

☐ Submit evidence in advance where the rules permit.

☐ The packet — and nothing more:

  • ☐ One summary page with the requested value and two or three reasons
  • ☐ The adjusted comparables table
  • ☐ The sales ratio table
  • ☐ Photographs — subject, comparables, and each condition problem
  • ☐ The record card with errors circled
  • ☐ Contractor estimates where condition is at issue

☐ ⚠ A thick packet reads as weakness. A clean two-page packet reads as preparation.

☐ The fifteen-minute script:

  1. ☐ State the ask. "I'm asking that the assessment be reduced from $340,000 to $286,000."
  2. ☐ Reason one, briefly. The record card error, with the measurement.
  3. ☐ Reason two. The uniformity ratio, with the table.
  4. ☐ Anticipate the answer. Address your own purchase price or any adverse fact directly.
  5. ☐ Close with the number again.

☐ ⛔ Do not argue the millage rate · the school budget · your household income · the percentage increase · the assessor's motives. None is within the board's authority.

☐ Ask at the close: "When will I receive the decision, and what is the deadline to appeal it?" Write down the answer.

Phase 9 — After the decision

☐ Calendar the next-level appeal deadline the day the decision arrives. ⚠ State board and tribunal deadlines are short and jurisdictional.

☐ Confirm whether the state-level proceeding builds a new record or reviews the old one.

☐ Consider an independent appraisal where the disputed amount is large.

☐ Judicial review is in state court. ⚠ 28 U.S.C. § 1341 bars federal district courts from restraining state tax collection where state remedies are adequate.

☐ Confirm the reduction was applied to the bill, not just to the assessment roll.

☐ ⭐ If you have a mortgage, send the corrected bill to the servicer and demand an escrow re-analysis in writing. It does not happen automatically — 12 U.S.C. § 2605, 12 U.S.C. § 2609, 12 CFR Part 1024.

☐ Check the annual escrow account statement for the projection, the cushion, and the shortage calculation. ⚠ Flood insurance requirements can also drive escrow — 42 U.S.C. § 4012a.

☐ Note the tax effects: state and local tax deduction subject to limitation — 26 U.S.C. § 164 · mortgage interest — 26 U.S.C. § 163 · gain exclusion on sale of a residence — 26 U.S.C. § 121.

Phase 10 — If the taxes are delinquent

☐ ⭐ Find the redemption deadline this week. Everything else is downstream of it.

☐ Ask about a payment plan. Most jurisdictions have one and few advertise it.

☐ Claim every exemption, including retroactively.

☐ Ask about a hardship deferral for elderly, disabled, or low-income owners.

☐ Check whether the assessment itself was wrong — an overassessment that produced the delinquency may be correctable.

☐ Notify the mortgage servicer. ⭐ They will usually advance the tax to protect their lien, and an advance to the loan balance beats losing the house.

☐ ⚠ Open mail from unfamiliar senders. Tax lien purchasers send the redemption notices.

☐ Understand the sequence: delinquency → a lien with priority over the mortgage → in some states a lien sale to an investor at a high statutory interest rate → a redemption period → a tax deed transferring title.

☐ Check notice sufficiency. Notice must be reasonably calculated to reach the owner — Mullane v. Central Hanover Bank & Trust Co.. ⭐ When certified mail is returned unclaimed, additional reasonable steps are required before the taking — Jones v. Flowers.

☐ ⭐ If property was already sold, ask about surplus proceeds. Retention of the amount above the debt is a taking requiring compensation — Tyler v. Hennepin County — with claims against local government under 42 U.S.C. § 1983, within the takings framework of Lingle v. Chevron U.S.A. and the public-use analysis of Kelo v. City of New London.

☐ If a foreclosure is also running, coordinate both — Defending a Residential Foreclosure: A Practical Checklist.

Phase 11 — Special situations

☐ Just bought? ⚠ Many jurisdictions reassess on transfer. Ask before closing what the assessment will be afterward.

☐ Renovating? A permit frequently triggers reassessment. Ask about a home improvement exemption, and note that ⭐ cost is not value.

☐ Rental or commercial? Use the income approach. ⭐ Vacancy, below-market leases, and obsolescence all argue value down, and assessors frequently value as if fully leased at market. Lease allocation of tax increases matters — Negotiating and Exiting a Commercial Lease: A Practical Checklist.

☐ Manufactured or mobile home? ⚠ Taxed as real or personal property depending on affixation and title. The classification changes the lien, the sale process, and the exemptions.

☐ Assessment pattern falls on a protected group? Fair housing law may reach it — 42 U.S.C. § 3604, 42 U.S.C. § 3605, with disparate impact under Texas Department of Housing and Community Affairs v. Inclusive Communities Project. See Documenting and Pursuing a Fair Housing Complaint: A Practical Checklist.

☐ Special assessments — sewer, sidewalk, lighting, improvement districts — are separate from ad valorem tax, with their own objection procedures. Read the bill line by line.

Who does what

The owner, the day the notice arrives. Read the deadline. Calendar it twice. The owner, that week. Pull the record card, measure the house, pull the neighbors' assessments. The assessor's office. The informal review — free, and frequently decisive. The board of review. Fifteen minutes, two grounds, one page. An appraiser. Only where the disputed amount is large. A contingency-fee appeal firm. Sensible for commercial; unnecessary for a measurement correction. Legal aid or a housing counseling agency. ⭐ Tangled title, exemption recovery, deferral applications, and tax-sale defense — which is how the problem actually presents. The mortgage servicer. The escrow re-analysis, after a win.

Failure modes, ranked

  1. Throwing away the notice.
  2. Missing the appeal deadline.
  3. Never pulling the property record card.
  4. Never measuring the house.
  5. Skipping the uniformity table — the cheapest strong evidence there is.
  6. Arguing the millage rate or the school budget to the board.
  7. Not requesting a specific number.
  8. Bringing a thick packet instead of two pages.
  9. Not asking whether the board can raise the assessment.
  10. Missing a payment-under-protest requirement and having the appeal dismissed.
  11. Never claiming the exemptions, or never asking about retroactivity.
  12. Leaving tangled title unfixed, losing the homestead exemption for years.
  13. Not sending a successful appeal to the mortgage servicer.
  14. ⚠ Not finding the redemption deadline when delinquent.
  15. ⭐ Assuming a completed tax sale is the end — Tyler v. Hennepin County may mean the surplus is still yours.

Appendix A — The two-hour appeal

For anyone who wants the whole thing on one page.

Minutes Task
0–5 Read the notice. Find the deadline. Calendar it twice
5–15 Call the assessor: informal review? can the board raise it? payment under protest?
15–35 Download the property record card. Check every line
35–50 Measure the house. Photograph the tape
50–70 Pull 5–10 neighbors' assessments from the public search
70–90 Pull recent sales for those properties; build the ratio table
90–105 Pull 3–5 comparable sales; build the adjusted table
105–115 Photograph condition problems; get one contractor estimate if needed
115–120 Write the one-page summary with a specific requested number

⭐ That is the entire appeal. Everything else in this checklist is refinement.

Appendix B — The one-page summary template

PROPERTY TAX APPEAL — [Parcel number] [Address] · Owner: [name] · Tax year: [year]

Current assessed value: $[__] Requested assessed value: $[__]

REASON 1 — The property record card overstates the improvements. The card shows [] square feet; the house measures [] (measurement and photograph attached, Exhibit 1). The card shows [a finished basement / a 2-car attached garage]; the property has [an unfinished basement / a detached 1-car garage] (Exhibit 2, photographs).

REASON 2 — The assessment is not uniform with comparable properties. Five comparable properties in the same neighborhood sold within the past 24 months. Their assessed-to-sale ratios are set out in Exhibit 3. The median is __%. The subject is assessed at __%. Applying the median ratio produces an assessed value of $[__].

REASON 3 — Condition. [The roof is at the end of its service life; estimate attached at $[] (Exhibit 4). This condition existed on the valuation date, as shown by the photograph dated [].]

THE ADJUSTED COMPARABLES indicate a market value of approximately $[__] (Exhibit 5).

REQUEST: Reduce the assessment to $[__].

[Name · address · telephone · email · date]

Appendix C — Five letters worth sending

☐ To the assessor, on receipt of the notice:

"Please send me the property record card for parcel [__], the neighborhood code and its boundaries, and the comparable sales relied upon in the current valuation. Please also advise whether an informal review is available and how to request one."

☐ On exemptions:

"Please advise what exemptions I may be eligible for on parcel [__], the application deadline for each, and whether any may be claimed retroactively. I am [an owner-occupant / age __ / a veteran with a __% service-connected disability rating / disabled]."

☐ To the board, filing the appeal:

"I appeal the assessment of parcel [] on two independent grounds: overvaluation and lack of uniformity with comparable properties. **I request that the assessed value be reduced to $[].** A two-page summary and exhibits are enclosed."

☐ To the mortgage servicer, after a win:

"The assessment on [address] was reduced effective [date]; the corrected bill is enclosed. I request a re-analysis of my escrow account and a revised monthly payment, together with a statement of any surplus, under 12 U.S.C. § 2605 and 12 CFR Part 1024."

☐ To the treasurer, if delinquent:

"I am the owner of parcel [__]. Please state the redemption deadline, the full amount required to redeem, and whether a payment plan or hardship deferral is available. I am also applying for [exemption], and request that any retroactive relief be applied to the delinquency."

Appendix D — The annual twenty minutes

☐ January. Photograph any condition problem as it exists on the valuation date. ☐ February. Re-verify every exemption on the bill; confirm none lapsed on a refinance, trust transfer, marriage, death, or occupancy change. ☐ Spring. ⭐ Open the notice the day it arrives. Decide within a week whether there is a case. ☐ Summer/fall. Check the bill: millage components, special assessments, exemption lines, and whether any appeal result was applied. ☐ Annually. Read the escrow statement; check the projection, cushion, and shortage math. ☐ ⚠ Any year the bill goes unpaid. Find the redemption deadline that week.

⭐ Twenty minutes a year, on a single house, over a decade, is worth more than most people's investment returns over the same period — using records they are already entitled to see, for free.
