About TaxByAddress

Property tax is the largest housing cost most people never price before they buy.

Rates change at county lines, school district boundaries and special district edges, and the seller's current bill tells a buyer little because assessment caps reset on sale. The information exists, spread across Census tables, state statutes and 3,000 county assessor websites. TaxByAddress puts it on one page per county, in the same format everywhere, and adds an estimator that applies it to a home value.

Who it is for

Buyers comparing neighbourhoods, owners checking whether their assessment is out of line, and anyone who needs the due date or the appeal deadline without digging through a county portal.

Who runs TaxByAddress

TaxByAddress is built and maintained by Abdul Sethi, a developer. The county figures come from a data pipeline that pulls the Census Bureau's American Community Survey for every US county. A state's pages go live only after its assessment rules, exemptions, due dates and appeal deadlines have been checked on that state's own revenue department website, and every page lists the sources behind it.

Independence and advertising

TaxByAddress is independently operated and funded by display advertising and, where marked, referrals to property tax appeal services. Advertising never influences the figures we publish. We are not tax advisers and do not give individual tax advice.
