How to appeal your property tax assessment (and win)
The short answer
Property tax appeals win surprisingly often — typically 30–60% of filed appeals get a reduction, because assessments are mass-produced and wrong in your favor-by-default only for the county. Pull your property record card, fix factual errors (square footage, bedroom count, condition), and build a comp set of 3–5 similar homes that sold or are assessed below yours. Start with the informal review; most wins happen there.
Why assessments are beatable
Assessors value thousands of homes with models, not walkthroughs. The result: your record card has your square footage from a 1998 addition that does not exist, your condition graded "good" while the 1978 kitchen says otherwise, and your value computed from a neighborhood average that ignores the busy road behind your fence. Mass appraisal is approximation — and an appeal with specific evidence beats the approximation most of the time.
Step 1: Fix the record card
Pull your property record card from the county assessor's site and check every field: living area, lot size, bedroom/bathroom count, garage, basement finish, condition grade, year built. Every error in your favor costs you money every year — a 200 sq ft phantom is worth real tax dollars annually. Factual corrections are the easiest win in the system: no hearing, just documentation (photos, measurements, the listing when you bought).
Step 2: Build the comp packet
Two kinds of comparables, 3–5 of each: homes SIMILAR to yours that SOLD recently below your assessed value (market evidence), and similar homes ASSESSED below yours (equity evidence — the "my neighbor with the same house pays less" argument, which is legally potent in most states). Screenshot the assessor's own records for the equity comps. Adjust for differences honestly — a comp with a pool you lack needs an adjustment or an explanation.
Step 3: Informal review first, formal hearing if needed
Most jurisdictions offer an informal review with the assessor's office before any formal board hearing — and it is where most reductions happen, because appraisers settle good evidence fast. Bring the record-card corrections and the comp packet, be pleasant, and ask for a specific number justified by the comps. If the informal review stalls, file the formal appeal before the deadline (typically 30–90 days after the assessment notice — miss it and you wait a year). The hearing is 10 minutes of the same evidence in front of a board; homeowners with packets win regularly.

Start freeQuestions people actually ask
- How much can a property tax appeal save?
- A successful appeal typically cuts the assessment 5–15% — worth hundreds to a couple thousand dollars per year, and the reduction usually carries forward to future years until a reassessment. An afternoon of paperwork for a recurring annual saving is among the best hourly rates in personal finance.
- Will appealing trigger a higher assessment or a re-inspection?
- Almost never — appeals that fail simply leave the assessment unchanged, and retaliatory re-inspections are both rare and often restricted. The real risk is only the filing deadline: miss it and the number locks for the year. There is no downside to a well-prepared appeal.
- Should I hire a property tax appeal service?
- For most homes, no — the process is genuinely one afternoon of DIY work, and services take 30–50% of first-year savings. They earn their cut on high-value homes, commercial property, or complex cases where the evidence work is real. Try the informal review yourself first; if it fails on a big number, bring in help for the formal round.
- My home's value dropped this year. Why did my taxes go up?
- Assessments lag the market and are often capped or phased (your assessed value can rise while market value falls, up to the cap). That gap is itself appeal evidence: recent comparable sales below your assessment are the strongest argument there is. Also check exemptions — homestead, senior, veteran, disability — which many owners never claim and which apply regardless of any appeal.
