A tax citation letter is not an official IRS term. It’s shorthand people use for the notices and letters the IRS sends when something on your account needs attention. The IRS itself labels these documents as notices (codes starting with “CP”) or letters (codes starting with “LTR”), and the code appears in the upper-right corner of the page.1Internal Revenue Service. Understanding Your IRS Notice or Letter Find that code first. It tells you exactly what the IRS wants, how urgent it is, and what your options are.
Confirm the Letter Actually Came From the IRS
Fake IRS notices are common, and a convincing one can pull your Social Security number and bank details straight out of you. Before you respond to anything, check it against the IRS’s own rules for how it contacts people.
- The IRS never starts contact by email, text, or social media. If that’s how you first heard from “the IRS,” it isn’t the IRS.
- The IRS never demands payment in gift cards, prepaid debit cards, or cryptocurrency. Neither does any private collection agency working on its behalf.
- The IRS doesn’t leave threatening, pre-recorded voicemails. Threats of immediate arrest are a scam.
To verify a paper letter, log into your IRS Online Account at irs.gov. Anything genuine the IRS has sent you will show up there. You can also call the IRS using the number listed on irs.gov and compare it to the number on your letter.2Internal Revenue Service. Ways to Tell if the IRS Is Reaching Out or if It’s a Scammer If a private collection agency contacted you, confirm the Taxpayer Authentication Number on its notice matches the one on the CP40 the IRS should have sent you first.
Identify Which Notice You Actually Have
The IRS sends dozens of different notices. A handful cover most of what taxpayers see, and the differences matter — some ask for money, some propose changes to your return, and some are the last warning before the IRS starts seizing property.
CP14, Balance Due
The first notice the IRS usually sends when you filed a return but didn’t pay in full. It shows what you owe, including penalties and interest already added. It isn’t a dispute. The IRS agrees with your return and wants the money.
CP501, Reminder of Unpaid Balance
A follow-up on an unpaid balance. If you already paid and the payment crossed in the mail, call the number on the notice. If you still owe and ignore this one, the IRS can file a Notice of Federal Tax Lien against your property.3Internal Revenue Service. Understanding Your CP501 Notice
CP2000, Income Discrepancy
This arrives when the income you reported doesn’t match what employers, banks, or other payers reported about you. It is not an audit. It’s a proposed adjustment, which could raise your tax, lower it, or wash out.4Internal Revenue Service. Understanding Your CP2000 Series Notice Sometimes the IRS is right because you forgot a 1099. Sometimes a third-party form was wrong. Either way, respond.
CP3219N, Notice of Deficiency (the 90-Day Letter)
The notice with real teeth. You have 90 days from the date on the notice (150 days if you’re outside the country) to file a petition with the U.S. Tax Court if you disagree with the proposed tax. Disputed amounts of $50,000 or less per tax year qualify for the Tax Court’s simplified procedures, which are more manageable without a lawyer.5Internal Revenue Service. Understanding Your CP3219N Notice Miss the 90 days and you lose the right to challenge the assessment in Tax Court before paying it.
LTR 1058, Final Notice of Intent to Levy
The IRS is telling you it’s about to start seizing property. Wages, bank accounts, retirement funds, and Social Security benefits are all on the table. The letter also warns that the IRS can file a federal tax lien and, under the FAST Act, ask the State Department to deny or revoke your passport.6Internal Revenue Service. Understanding Your LT11 Notice or Letter 1058 If you’ve reached this stage, act now: pay, arrange a payment plan, or request a Collection Due Process hearing.
What to Do Once You’ve Read It
Read the entire letter before you do anything. IRS notices are specific. They name the tax year, the exact dollar amount at issue, and a deadline for your response. That deadline is the thing that matters most. Missing it can cost you appeal rights, add penalties, or push the case into collections.
Then gather your records. If the notice involves income you didn’t report, pull the W-2 or 1099. If it questions a deduction, find the receipts or bank statements. If it says you didn’t file a return, locate proof that you did. Having documents in hand before you call or write saves hours.
If you agree and owe money, pay what you can by the deadline. Pay online at irs.gov/payments, mail a check in the envelope the IRS sent, or set up a payment plan. If you disagree, respond in writing with an explanation and supporting documents. Use certified mail with return receipt, or the online portal if the notice lists one. Keep copies of everything you send.
For anything beyond a routine balance-due notice — a large CP2000 adjustment, a Notice of Deficiency, a levy letter — think about hiring a tax attorney, enrolled agent, or CPA who handles IRS disputes. They catch mistakes you’d miss and know how to frame a response the IRS will take seriously.
If You Cannot Pay the Full Amount
Owing the IRS is stressful. Ignoring the bill is still worse than any alternative, because every month adds a failure-to-pay charge of 0.5% of the unpaid tax (capped at 25%) on top of interest that compounds daily, and if you also didn’t file on time the failure-to-file penalty runs at 5% per month up to 25%.7Office of the Law Revision Counsel. 26 US Code 6651 – Failure to File Tax Return or to Pay Tax The IRS offers several formal ways to handle a balance you can’t clear at once.
Installment Agreements
Pay the balance in monthly installments. If you owe $50,000 or less in combined tax, penalties, and interest, and have filed all required returns, you can apply online through the IRS Online Payment Agreement tool. Above $50,000, you’ll need to submit Form 9465 with a financial disclosure.
If you owe $10,000 or less excluding penalties and interest, have filed returns for the past five years, and haven’t had a recent installment agreement, the IRS is required to approve your request as long as you can pay within 36 months. Low-income taxpayers earning below 250% of the federal poverty level can apply for reduced or waived setup fees.
Offer in Compromise
An offer in compromise lets you settle for less than you owe. The IRS considers one when there’s a genuine dispute about whether you owe the tax, when your assets and income are too low to ever pay in full, or when collecting the full balance would create an unfair economic hardship.8Internal Revenue Service. Topic No. 204, Offers in Compromise
The IRS generally won’t accept an OIC if you could pay through an installment agreement instead. You must have filed all required returns, made estimated payments for the current year, and received a bill for at least one of the debts included in the offer. The IRS evaluates your “reasonable collection potential” (assets plus expected future income minus basic living expenses) and typically won’t take less than that.8Internal Revenue Service. Topic No. 204, Offers in Compromise
Currently Not Collectible Status
If paying anything would leave you unable to cover basic living expenses, ask the IRS to mark your account currently not collectible. This stops active collection, including wage levies and bank seizures. You’ll typically submit Form 433-F with financial documentation.
Currently not collectible is not forgiveness. Interest and penalties keep running, the IRS can still file a lien, and the agency will periodically recheck your finances. The upside: the 10-year collection clock keeps ticking, so if the IRS still can’t collect when that statute expires, the debt goes away.
Your Right to Appeal
You can challenge almost any IRS action before it becomes final. For most proposed adjustments, including exam results and proposed deficiencies, the IRS sends a “30-day letter” giving you 30 days to file a written protest with the IRS Independent Office of Appeals.9Internal Revenue Service. Preparing a Request for Appeals Some letters give 60 days, and Letter 692 (consideration of additional findings) gives only 15. Always use the deadline printed on your letter.10Internal Revenue Service. Letters and Notices Offering an Appeal Opportunity
Appeals is a separate office from the division that examined your return, and it exists to resolve disputes without court. If Appeals doesn’t produce an agreement and you’ve received a formal Notice of Deficiency, your next step is a Tax Court petition. For collection actions like liens and levies, you can request a Collection Due Process hearing, which also goes through Appeals.
What Happens If You Ignore the Letter
The IRS doesn’t forget. Each unanswered notice triggers the next one in an escalating sequence, and eventually the agency stops asking and starts taking.
Liens and Levies
A federal tax lien is a legal claim on everything you own, including property you acquire after it’s filed. Tax liens no longer appear on credit reports, but the filing is public record. That still makes it harder to sell property, refinance a mortgage, or get new credit.
A levy is the actual seizure. The IRS can take wages, bank accounts, retirement accounts, Social Security benefits, rental income, and accounts receivable. It generally issues a levy only after assessing the tax, sending you a bill, waiting for you to not pay, and then sending a final notice giving you 30 days’ warning.11Internal Revenue Service. What Is a Levy?
Passport Denial or Revocation
If your total tax debt including penalties and interest exceeds $66,000, the IRS can certify you to the State Department as having “seriously delinquent tax debt.” That certification can get your passport application denied or your existing passport revoked. The $66,000 threshold is adjusted annually for inflation.12Internal Revenue Service. Revocation or Denial of Passport in Cases of Certain Unpaid Taxes
The IRS won’t certify you if you have an approved installment agreement, a pending or accepted offer in compromise, currently not collectible status due to hardship, a pending Collection Due Process hearing request, or tax-related identity theft on record. Taxpayers in a designated combat zone are also exempt.12Internal Revenue Service. Revocation or Denial of Passport in Cases of Certain Unpaid Taxes
How Long the IRS Has to Act
Two separate clocks govern how long the agency can pursue you.
The IRS generally has three years from the date you filed a return to assess additional tax on it. File early and the clock starts on the filing deadline, not your submission date. There’s no time limit at all if you filed a fraudulent return or never filed one.13Office of the Law Revision Counsel. 26 US Code 6501 – Limitations on Assessment and Collection
Once tax is assessed, the IRS has 10 years to collect. This is the Collection Statute Expiration Date. After 10 years the debt expires.14Internal Revenue Service. Time IRS Can Collect Tax
Several common actions pause that 10-year clock. Requesting an installment agreement suspends it while the IRS reviews. Filing for bankruptcy suspends it for the case plus six months. Submitting an offer in compromise suspends it while the offer is pending. Requesting a Collection Due Process hearing suspends it until the hearing concludes.14Internal Revenue Service. Time IRS Can Collect Tax Each of these moves is often worth making anyway. Just know that each one extends the window the IRS has to collect from you.
