Answers to Common Questions
What is the notice telling me?
This notice is telling you that we intend to issue a levy against certain property or rights to property because you still have a balance due on one of your tax accounts. You must pay this amount immediately to avoid this. It is also telling you that we will begin searching for other assets on which to issue a levy. We may also file a Federal Tax Lien, if we have not already done so.
What do I have to do?
Pay the amount due shown on the notice. Mail us your payment in the envelope we sent you. Include the bottom part of the notice to make sure we correctly credit your account.
If you can't pay the whole amount now, call us at the number printed at the top of the notice to see if you qualify for an installment agreement.
How much time do I have?
You should pay your balance due by the due date shown on your notice.
What happens if I don't pay or contact the IRS?
If you don't pay the amount due, we may send you a notice giving you a right to a hearing before the IRS Office of Appeals if you have not already received such a notice. We may then seize ("levy") your property or rights to property. Property includes:
- Wages, real estate commissions, and other income
- Bank accounts
- Business assets
- Personal assets (including your car and home)
- Social Security benefits
This is your notice of intent to levy as required by Internal Revenue Code section 6331(d).
If you don't pay the amount due or call us to make payment arrangements, we can file a Notice of Federal Tax Lien on your property at any time, if we haven’t already done so.
If the lien is in place, you may find it difficult to sell or borrow against your property. The tax lien would also appear on your credit report ― which may harm your credit rating ― and your creditors would also be publicly notified that the IRS has priority to seize your property.
Who should I contact?
If you have any questions about the notice, call us at the number printed at the top of the notice. A customer service representative will assist you.
What if I don't agree or have already taken corrective action?
If you do not agree with this notice, contact us immediately at the number printed at the top of the notice. We will do our best to help you. If you have already paid this liability or arranged to pay it with an installment agreement, you should still call us at the number printed at the top of the notice to make sure your account reflects this.
