A Notice of Levy is another method the IRS may use to collect taxes that are not paid voluntarily. This means the IRS can legally confiscate money or assets to satisfy a tax debt. This could include a person's wages, bank accounts, Social Security benefits, and retirement income. If a tax liability remains unpaid, the IRS may also levy assets such as a car, boat, or real estate.

In addition, when a person has an outstanding tax liability, any future federal tax refunds that are due will be taken to offset by the amount owed. Any state income tax refunds due may also be levied, and the proceeds applied to the liability.

The law requires the IRS to notify a taxpayer in writing not more than 5 business days after the filing of a lien. The IRS may give this notice in person, leave it at the taxpayer's home or usual place of business, or send it by certified or registered mail to the last known address.
