The IRS can legally seize your property to satisfy your tax debt. They following three conditions must be met before the IRS can proceed with a levy:
If you do not pay your taxes or set up a collection alternative, the IRS may levy your paycheck, bank accounts, retirement accounts, or any property being held by third parties. They may also seize and sell any property that you own, including your home.
Most levies only attach to your rights to assets that exist when the levy is served. The exception to this is a wage garnishment which will not end until the debt is paid in full, the levy is released (usually because you have set up a collection alternative), have filed a bankruptcy petition, or the Statute of Limitations on collections has expired.
