Tax appeals · Updated July 2026
Are your property taxes too high?
Everyone feels like their property taxes are too high. The useful question is narrower: is your bill too high relative to the rules — because the county says your home is worth more than it actually is? That’s the part you can fight, and the part that pays you back every year when you win.
Your tax bill is two numbers multiplied together: a tax rate you mostly can’t contest, and an assessed value you absolutely can. This guide is about telling those apart, spotting a genuine over-assessment, and deciding whether it’s worth acting on.
Rate problems vs. value problems
Tax rates are set by budgets — school districts, municipalities, counties voting to spend. If rates rose, your remedy is the ballot box, not an appeal. Appeals exist for the other half of the equation: the assessed value, the county’s claim about what your home is worth.
This distinction explains the most common appeal disappointment: homeowners whose values are accurate but whose rates jumped. Before investing any effort, check which number actually moved on your bill. If your assessment jumped while the market around you cooled or stayed flat, you’re in appeal territory.
The three signs of an over-assessment
First: the implied market value test. Work out what market value your assessment claims (divide by your state’s assessment ratio if it uses one — the notice usually shows it). If that number is clearly above what your home would sell for, the assessment is wrong on its face.
Second: the record-card test. Pull your property record from the assessor’s website and check the facts — square footage, bedroom and bath counts, lot size, garage, condition rating. Mass-appraisal models are only as good as these inputs, and errors here are both common and the easiest wins.
Third: the neighbor test. Similar homes on your street with meaningfully lower assessments suggest yours drifted. Equity arguments alone rarely win, but they’re a strong signal that the value evidence will be on your side.
- Implied market value above realistic sale price → value case
- Wrong square footage, bed/bath count, or condition on the record card → correction case
- Similar neighbors assessed meaningfully lower → worth checking the comps
What actually changes the number
Assessors and review boards are numbers people drowning in cases. What moves them is the same evidence they’d produce themselves if they had time: recent sales of comparable homes, adjusted for the differences, supporting a specific value as of the assessment date. That is, precisely, what a licensed appraisal contains.
What doesn’t move them: your tax bill’s size, your fixed income, Zillow screenshots, or listings that never sold. Boards can’t act on hardship — they can only act on value. Bringing the right kind of evidence is most of the battle.
The math of whether it’s worth it
A successful appeal saves you the tax on the removed value — every year the correction stands. Estimate it: (over-assessment amount) × (your effective tax rate). A home over-assessed by a meaningful margin in a high-rate state can recover the cost of professional evidence within the first year, then keep saving.
And if the numbers aren’t on your side, the honest move is to know that before you spend anything. That’s exactly what our five-dollar savings check is for: your actual assessment against real comparable sales, with a straight answer either way.
Questions people ask
One of two reasons: your tax rate rose (a budget decision you can’t appeal) or your assessed value rose (a value claim you can). Compare this year’s notice to last year’s to see which moved — reassessment years often produce sharp value jumps.
It’s rare but theoretically possible in some jurisdictions if the evidence shows you’re under-assessed. It’s one more reason to check the numbers before filing — an honest pre-check tells you whether you have a case at all.
For a residential appeal, generally no — the boards are built for homeowners. What you need is credible evidence of market value. Attorneys become relevant in court-level appeals or complex commercial cases.
