In Beaver County PA, its $20.00 for a 3 year county tax certification.  Municipal and school fees vary from free to $30.00 for the information.  When taxes become delinquent and are turned into the Tax Claim bureau, the info on the computer is free but you have to pay have for a copy or to have the info certified.  Without the cert, they only give you status on the current tax year.  No dates, amounts etc.  The information is always free to the property owner.
