What to gather for your Kings County appeal
- Your parcel number and assessment notice, with the tax year and assessed value you are disputing.
- Recent sales of similar properties in Kings County near the relevant valuation date. Explain differences in size, location and condition.
- Photos, repair estimates or corrected property records that support your opinion of value.
- A copy of everything you submit and confirmation that the county received your application.
For a regular decline-in-value appeal, focus on market value as of January 1. A lower asking price or an online estimate alone does not establish what the county should assess. Savings depend on the approved value reduction and your property's tax rates.
