Automated Lien System (ALS) Database Listing

 

A standard listing of business liens extracted quarterly from the IRS Automated Lien System database is available in pipe-delimited text format on compact disc (CD).

The database from which this information was extracted doesn't represent the legal filings of notices of federal tax liens. The data, therefore, may be incomplete and, in some instances, inaccurate. For official purposes, confirm all data with the right local filing jurisdictions.

Each lien record in the extracted file contains multiple fields, including:

  • Lien ID Number
  • TP ID Number
  • TP Name and Address
  • Lien Status
