Property data, United States
Federal Tax Lien Data
IRS federal tax liens combined with property tax liens and delinquency, with the taxpayer's phone, email and property where matched.
Federal tax lien filings from county recorders and the IRS, joined to property tax liens and delinquency rolls, then matched to the taxpayer's contact information and, where they own it, their property record. Delivered monthly with a DNC scrub option.
This is a well-worn file for tax resolution firms; ours differs in the property join and the phone quality, which we verify against carrier line-type data.

How it is built
Liens are collected from recorder indexes and normalized. Taxpayers are matched to our people graph on name and address; phones are verified for line type and scrubbed against federal and state DNC lists plus known TCPA litigators.
Questions we get
