Appeal Your Assessment — The Property-Tax Challenge Kit

1 Your property

Start with what the town claims, and what you think it's really worth. The name/address fields only fill your appeal letter — nothing leaves your browser.

Your name For the appeal letter only

Property address For the appeal letter only

Assessed value The number on your tax bill

Tax rate — $ per $1,000 On your tax bill (e.g. 22.50 ≈ 2.25%)

Target assessment ratio % Most towns: 100. Some counties publish a common-level ratio — use yours.

Your market-value estimate What would it sell for tomorrow? Be honest, not hopeful.

Your living area (sq ft)

Parcel / block-lot Optional — for the letter

2 Your comps

Appeals are won on comparable sales — recent sales of similar homes nearby. Adjust each comp: was it nicer than yours? Knock the price down. Worse? Push it up. Newer sales count more.

3 The verdict

Comp-adjusted value × your assessment ratio = what your assessment should be. The gap is what you're being overcharged on.

The method behind it

Assessments are mass appraisals. Your town didn't tour your kitchen — it ran a model. Models get stale, especially after renovations change a neighborhood or a reval is years overdue.
Appeals are won on comps. The comparable-sales approach is what assessors and boards respect: recent arm's-length sales of similar homes, adjusted for condition and size. That's the grid above.
Newer comps weigh more. A sale from last month beats one from last year — the weighting is automatic.
The ratio is the law. Some jurisdictions assess at 100% of market value; others publish a common-level ratio. Your appeal asks: is my assessment fairly proportioned to market value?
Deadlines are everything. File late and you're done. Calendar yours now.
