A lien is different from a levy. A levy takes your property or assets, where a lien secures the government’s interest in your property.
A federal tax lien is a legal claim to your property (such as real property, securities and vehicles), including property that you acquire after the lien arises.
If the IRS files a lien against your business, it attaches to all business property and to all rights to business property, including accounts receivable.
A lien is just one of the collection procedures the IRS may use if you file or pay your taxes late. Publication 594, The IRS Collection Process, helps you understand the entire IRS collection process.
