How to use this guide Start with the notice you actually received. The notice number, date, balance, deadline, tax period, and telephone number on your letter matter more than a general sequence printed anywhere else. Not every taxpayer receives every notice, and notices do not always arrive in the same order. Use the date and phone number on your notice when you respond. You can also view notices in an IRS Online Account. For official background, see Publication 594, Publication 1, and Publication 1660.
First steps for almost every balance-due notice Open the notice, confirm the tax year and amount, and save a copy. If you agree with the balance and can pay it, pay by the date shown. If you cannot pay in full, look at a payment plan and contact the IRS promptly. If you disagree, call the number on the notice and be ready to explain why. Do not ignore the letter. Interest and, where applicable, penalties can continue while a balance remains unpaid. A timely response also gives you a chance to address an error or discuss payment before collection becomes more serious.
CP14 — balance due on unpaid taxes What it is CP14 says the IRS believes you owe money on unpaid taxes. It is a balance-due notice, not a levy notice.
What the IRS says it means The IRS asks you to pay the amount by the due date on the notice. If the full amount is paid by that date, interest does not apply. Interest accrues on an unpaid amount after that date. A late-payment penalty may apply if you cannot pay the full balance.
What to do Pay by the listed due date if you can. If you cannot, contact the IRS by that payment due date or apply online for a payment plan. If the balance is wrong, contact the IRS using the number on the notice.
What may come next if you do not respond The IRS may continue its collection notices. Read each new letter for its own deadline and options.
CP501 — reminder that a balance remains What it is CP501 is a reminder that you owe a balance. It is sent because the IRS has not received payment or a response to an earlier notice.

What the IRS says it means The balance is still open. Interest accrues, additional penalties may apply, and a Failure to Pay penalty may apply. If you do not pay, arrange payment, or contact the IRS, it can file a Notice of Federal Tax Lien.
What to do Pay by the due date, make a payment plan, or call if you disagree. Follow the notice instructions if you want to request an appeal under the Collection Appeals Program (CAP) before collection action.
What may come next if you do not respond The IRS may file a Notice of Federal Tax Lien and continue collection. Ask about possible penalty removal by the notice due date.
CP503 — second reminder What it is CP503 is a second reminder that you still owe a balance. The IRS sends it when it has not received payment or a response to earlier notice or notices.
What the IRS says it means The account remains unpaid. The IRS says it may file a Notice of Federal Tax Lien if it has not already done so.
What to do Pay by the due date, apply online for a payment plan, mail an installment agreement request, or call if you disagree. A CAP appeal may be available; follow the instructions in your notice.
What may come next if you do not respond A Notice of Federal Tax Lien may be filed. A further collection notice may also follow, with different consequences and rights.
CP504 — notice of intent to levy What it is CP504 is a final reminder concerning an unpaid balance and a Notice of Intent to Levy under IRC 6331(d). The IRS says it will begin searching for other assets on which to issue a levy. It may also file a Notice of Federal Tax Lien if it has not already done so.

What the IRS says it means This notice can lead to a levy of your state tax refund if the amount due is not received within 30 days from the date of the notice. The IRS may also serve a Disqualified Employment Tax Levy or a Federal Contractor Levy in the situations described in Publication 594. For most other levies—such as wages, bank accounts, business assets, personal assets, or Social Security benefits—the IRS generally still sends a later notice that gives you the opportunity to request a Collection Due Process (CDP) hearing, unless you already received one. That later notice may be LT11, Letter 1058, or CP90. CP504 alone does not mean your paycheck will be taken in 30 days.
What to do Pay immediately if you can. If you cannot, pay what you can and contact the IRS at the number on the notice, or apply online for a payment plan. Follow the notice instructions if you want to request a CAP appeal before collection action. Respond now; do not wait for a later letter.
What may come next if you do not respond The IRS can levy a state tax refund after the stated 30-day period. If a balance remains, it may send a notice giving the right to a hearing before the IRS Independent Office of Appeals, unless you have already received that notice. After the required notice process, other property may be subject to levy.
LT11 or Letter 1058 — levy notice with CDP hearing rights What it is LT11 and Letter 1058 accompany the right to request a Collection Due Process hearing. They are serious collection notices and should be read with the deadline printed on the notice.
What the IRS says it means The IRS identifies property that may be levied for unpaid taxes, including wages and other income, bank accounts, business assets, personal assets such as a car or home, Alaska Permanent Fund Dividends, state tax refunds, and Social Security benefits.
What to do Use the deadline on the notice. You may pay, pursue a payment arrangement, or request a CDP hearing with Form 12153. Read Publications 594 and 1660 before choosing how to respond.
What may come next if you do not respond After the notice process, the IRS may levy property or rights to property. The exact next step depends on the notice and account, so use the letter's date and instructions.

CP90 — intent to levy and CDP hearing rights What it is CP90 says that the IRS intends to levy certain assets for unpaid taxes and is informing you of your right to a Collection Due Process hearing.
What the IRS says it means A CDP hearing is an opportunity to appeal the intent to levy and address other issues with your tax situation.
What to do Pay what you owe, request a payment plan, or request a CDP hearing using Form 12153. Use the deadline shown on CP90.
What may come next if you do not respond The IRS may move forward with levy action after the applicable notice process. Do not assume that an earlier balance-due notice preserves the options or deadline in CP90.
Letter 3172 — federal tax lien filing and CDP rights What it is Letter 3172 is the Notice of Federal Tax Lien Filing and Your Right to a Hearing Under IRC 6320. It tells you that the IRS has filed a Notice of Federal Tax Lien (NFTL); Form 668(Y)(c) is enclosed.
What the IRS says it means A lien is a legal claim against property to secure payment of a tax debt. The federal tax lien generally attaches to property you own now and property you acquire while the lien remains in effect. The NFTL is a public record. The Taxpayer Advocate Service says NFTLs no longer appear on credit reports, but a potential creditor may still find one through other resources, including public records. Penalties and interest may continue to increase.
What to do Pay or make payment arrangements. If you want a CDP hearing, request it with Form 12153 by the deadline in the letter. If you miss that deadline, you may be able to request an Equivalent Hearing within one year of the notice date, but you generally will not be able to petition the U.S. Tax Court if you disagree with the Appeals decision. Form 9423, Collection Appeal Request, may also be available.
What may come next if you do not respond The public lien filing remains part of the collection picture while the debt is unresolved. The Taxpayer Advocate Service lists three release events: the balance is paid in full, the IRS's time to collect expires, or the IRS accepts an offer in compromise. For an accepted offer, Form 656 says the lien for the periods in the offer

will generally be released within 45 days after the final offer payment is received and verified. Under the conditions stated in the sample letter, the IRS will issue Form 668(Z), Certificate of Release of Federal Tax Lien, within 30 days after full payment of the debt, including penalties and interest. A seriously delinquent tax debt may affect the ability to obtain or keep a U.S. passport if the IRS certifies the debt. Review the letter and IRS.gov for current information.
CP523 — installment agreement default or intent notice What it is CP523 tells you the IRS intends to terminate your installment agreement and seize your assets because the agreement is in default. The notice states the reason.
What the IRS says it means If you take no action, the IRS will terminate the agreement and begin collection action, which can include filing a federal tax lien or levying your wages or bank accounts.
What to do Make your payment before the termination date on the notice. Contact the IRS at the number on the notice as soon as possible, and no later than 30 days from the notice date, to see whether the agreement can be reinstated. You may have to pay a reinstatement fee or pay any new tax in full. If you disagree with the termination, you can appeal and request a hearing with the IRS Independent Office of Appeals. To help avoid default, pay at least the minimum monthly payment when due; file required returns on time; pay new taxes in full and on time; and contact the IRS to change an existing agreement if you cannot do so.
What may come next if you do not respond There may be a reinstatement fee if a plan goes into default. Penalties and interest continue until the balance is paid in full. Future refunds are applied to the tax debt, and you should continue scheduled payments even when a refund is applied. See the notice and the official CP523 page for the account-specific next step.
If you cannot pay in full Payment plans An IRS payment plan may let you pay over time. A short-term plan is for payment in 180 days or less and has a $0 setup fee, though penalties and interest can continue until paid in full. Individuals who owe less than $100,000 in combined tax, penalties, and interest may qualify to apply online for a short-term plan. For long-term installment agreements, the following published setup fees were current on IRS.gov as of November 14, 2026. Fees and rules can change, so confirm them at IRS.gov before applying.

For qualifying low-income individuals, the direct-debit setup fee is waived. For a non-direct-debit plan, the low-income fee is $43 and may be reimbursed if conditions are met. Card payments carry separate processor fees. Form 13844 can be used to request low-income status if the IRS system does not identify you as lowincome. The IRS describes Simple Payment Plans as long-term plans for qualified taxpayers that do not require a collection information statement, lien determination, or trust fund recovery penalty determination. Individuals may qualify at $50,000 or less in assessed tax, penalties, and interest if all required returns have been filed. The IRS says more than 90% of individual taxpayers will qualify for a Simple Payment Plan; that is an IRS statement, not a promise for any particular account. Pay each required amount when due, file future returns on time, and pay future taxes in full and on time. The IRS says it generally will not take enforced collection actions while a payment plan is being considered. When an installment agreement is requested, with certain exceptions, the IRS is generally prohibited from levying while the request is pending; its time to collect is suspended or prolonged during that period. A payment plan does not necessarily prevent a lien.
Currently Not Collectible status If you cannot pay because of financial hardship, the IRS may temporarily delay collection and place an account in Currently Not Collectible (CNC) status. It may ask for financial information and documents about income, monthly living expenses, bank accounts, property, and other assets, including Forms 433-F, 433-A, or 433-B. CNC does not forgive or cancel the balance. Most collection activities are temporarily suspended, but penalties and interest continue. The IRS may later review your finances, resume collection if your ability to pay improves, file an NFTL, or apply a federal refund to the debt. To request CNC, call the number on your bill or notice or 800-829-1040.
Offer in compromise An offer in compromise (OIC) is a way to settle tax debt for less than the full amount if you qualify. The application fee is $205 plus a first or initial payment, unless an exception applies. Low-income individuals do not pay the fee or initial payment while the IRS considers the offer. There is no application fee for an offer based on doubt as to liability. The IRS recommends its OIC pre-qualifier and an Individual Online Account eligibility check. An offer is not right for every taxpayer, and qualification is not guaranteed.

Lien versus levy A lien is a legal claim against property to secure payment of a tax debt. A levy is the legal seizure of property to satisfy that debt. A Notice of Federal Tax Lien is a public record and may affect credit or a sale of property. An IRS levy is not a public record.
