The IRS (irs.gov) generally sends letters regarding specific issues like tax return errors, identity verification, or account balance updates. In the case of unpaid taxes, the IRS typically sends five notices for individuals (four for businesses) over several months before taking collection actions like levies.
We may send you a notice or letter if: You have a balance due. Your refund has changed. We have a question about your return.
The good news is that normally the IRS sends you five letters (five for individuals and four for businesses) before actually seizing your assets. These notices are about five weeks apart so that you have at least four or five months to prepare for the final notice.
The IRS issues different types of letters—known by codes like CP2000, CP504, and Letter 1058—to communicate specific tax issues. These can involve underreported income, missed payments, audit requests, or enforcement actions like liens and levies. If you've received a notice, don't ignore it.
Most IRS letters and notices are about federal tax returns or tax accounts. Each notice deals with a specific issue and includes any steps the taxpayer needs to take. A notice may reference changes to a taxpayer's account, taxes owed, a payment request or a specific issue on a tax return.
One-time forgiveness, officially known as First-Time Penalty Abatement (FTA), is an IRS program that allows qualified taxpayers to have certain penalties removed from their tax accounts.
Here's what happens if you ignore the notice:
The IRS will make changes to your return (like adding income or removing deductions and/or credits). The IRS will propose taxes and possibly penalties, and you'll get a “90-day letter” (also known as a statutory notice of deficiency).
The IRS mails letters or notices to taxpayers for a variety of reasons including:
Notice of Tax Due and Demand for Payment, Notice CP14, Balance Due $5 or More, No Math Error, is the first and most common notice sent to taxpayers.
An IRS audit letter typically contains the taxpayer's name, tax ID number, contact information, and a request for additional documentation to support claims on the tax return. It may also include the name of the IRS officer handling the case and invite the taxpayer to a meeting.
The IRS escalates its collection efforts when the amount owed exceeds $25,000, which can result in severe penalties such as asset seizure, bank levy, wage garnishment, and even passport revocation. If you're unsure how much you owe, you can find more information and guidance here.
The IRS is a government agency and the audit letter is sent by certified mail.
The IRS waits to record most tax liens until after it has sent all five notices in the collection notice stream and hasn't received payment. You'll want to avoid a Notice of Federal Tax Lien. Liens can affect your ability to attract new business clients, secure and maintain credit, and obtain employment.
You know the IRS might be investigating you through official mail (first contact), phone calls (often with automated messages to IRS.gov), or in-person visits, but signs of a criminal probe include contact with IRS Criminal Investigation (CI) agents, subpoenas to you or your bank, questions to your accountant/bank, unusual account activity (freezing/refusing transactions), or agents suddenly going silent after an audit. Key indicators are official IRS letters, contact from CI special agents, third-party inquiries, and formal summonses for records, signaling serious scrutiny beyond a simple audit.
You can find digital copies of most IRS notices in your online account, under the 'Notices and Letters' section.
Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
You receive a notice or letter from the IRS about a balance due on your account, missing returns, a lien, or a levy. There are several collection alternatives available to you to resolve these issues.
The IRS sends letters now (typically early in the year or year-round) for various reasons, including matching tax return info to third-party data (like W-2s/1099s), questioning discrepancies, requesting identity verification, notifying of account changes, asking for payments on balances due, or informing you about a return processing delay or change to your return, so you should always open and read IRS mail carefully, as it requires action or provides important info about your taxes, often concerning a discrepancy.
Check which tax year the notice is for and follow the instructions provided; you usually have 30 days to respond. Compare the IRS adjustments to your records and tax return. If you agree with the notice, indicate that on the response form and send a check or money order for any additional taxes due.
What happens if you ignore it: After the deadline passes, the IRS can levy bank accounts, garnish wages, and seize property without further notice. You lose critical appeal rights that would have stopped these actions.
Remember, you will be contacted initially by mail. The IRS will provide all contact information and instructions in the letter you receive. If we conduct your audit by mail, our letter will request additional information about certain items shown on the tax return such as income, expenses, and itemized deductions.
You can get in trouble immediately for not filing taxes if you owe money, facing failure-to-file penalties (5% monthly, up to 25%) plus interest, but there's no set time limit; the IRS can pursue unfiled returns indefinitely, with the statute of limitations only starting once you file, potentially leading to Substitute for Returns (SFRs), liens, levies, and even criminal charges in severe cases of willful evasion, so filing voluntarily, even late, is crucial to stop penalties from escalating and to claim refunds.
