My research has uncovered TWO WAYS TO MOTIVATE THE IRS TO RELEASE THEIR LIENS
(Little utilized statutory method to motivate the IRS to release their notices of lien without doing a remove lien suit)

ONE:

If the IRS has placed a tax lien on your property you can make an administrative demand that the IRS release the lien on the basis that the liability is:
“LEGALLY UNENFORCEABLE”

TWO:

If there are IRS tax liens on your property you can make an administrative demand that the IRS withdraw those liens on the basis that federal tax lien was not filed:
IN ACCORDANCE WITH
“ADMINISTRATIVE PROCEDURES”

PACKAGE INCLUDES:

The package includes:

· Current statutes & regulations entitling you to the withdrawal of federal tax liens including regulations setting forth mailing deadlines for notices of IRS tax liens
· Internal Revenue Manual provisions on the processing of registered mail for notices of IRS tax liens
· The Treasury Inspector General Audit report showing 95% of property liens are procedurally defective
· A sample demand letter to withdraw a property lien because of a procedural defect
· A FOIA asking for the Postal Form the IRS is to maintain for federal tax liens
· A Case discussing IRS registered mail process
· A Supreme Court decision-IRS must follow procedure laid out by law
· A Supreme Court decision saying that deadlines set by Congress respecting IRS tax lien notices must be kept
· Area Director addresses to send your tax lien removal demand letter to
· Technical Service addresses to send your tax liens demand letter to
