What Happens If You Ignore an IRS Notice?

It’s tempting to set an unopened IRS letter aside and deal with it later.

Later gets busy. Later turns into next month. And before you know it, that first notice has multiplied into something much harder to manage.

The good news: the IRS doesn’t jump straight from a polite letter to seizing your bank account. It’s a process, with clear stages, and at nearly every stage you still have options.

Here’s what that escalation actually looks like, and where you can step in to stop it.

Stage One: The Notice

This is where it starts, and it’s the easiest place to fix a problem. A balance due notice (often a CP14) states what you owe and why.

At this point, interest and a failure-to-pay penalty are already accruing, but the amount is usually manageable and your options are wide open. You can pay it, dispute it if you think it’s wrong, or set up a payment plan.

How to stop it here: Respond by the date on the notice. If you agree with the balance, pay it or request an installment agreement. If you don’t agree, follow the instructions for disputing it and include documentation.

This is the cheapest, least stressful exit ramp in the entire process.

Stage Two: Follow-Up Notices

If the first notice goes unanswered, the IRS doesn’t just repeat itself. Each subsequent notice (CP501, CP503, CP504) escalates in tone and consequence.

By the time you reach a CP504, the letter will explicitly warn that the IRS intends to levy your state tax refund and may pursue other assets. This is also typically the point where a Notice of Intent to Levy becomes part of the conversation, which starts a 30-day countdown with legal weight behind it.

How to stop it here: The math hasn’t gotten any harder yet, only the warnings have gotten louder. Reach out to the IRS or your CPA now. Installment agreements, penalty abatement for reasonable cause, and offers in compromise are all still on the table.

The longer this stage stretches out, the fewer options are available.

Stage Three: The Federal Tax Lien

If a balance still isn’t resolved, the IRS can file a Notice of Federal Tax Lien. This is a legal claim against your property, which is public record and will show up in title searches and, in many cases, credit reports and background checks. It attaches to everything you own or acquire while it’s in place, including real estate, vehicles, and financial assets.

A lien doesn’t take anything from you directly, but it makes selling, refinancing, or borrowing against those assets significantly harder.

How to stop it here: Paying the balance in full releases the lien. If full payment isn’t realistic, an installment agreement, an offer in compromise, or a hardship status can sometimes get a lien withdrawn or subordinated.

This is more complicated territory, and it’s a good place to bring in a CPA who deals with IRS collections regularly.

Stage Four: The Levy

A levy is different from a lien. Where a lien is a claim, a levy is action. This is the IRS actually taking property or funds: garnishing wages, emptying a bank account, or seizing other assets.

Before this happens, you’ll receive a Final Notice of Intent to Levy, which gives you 30 days to respond and, critically, the right to request a Collection Due Process hearing. That hearing pauses the levy while it’s being reviewed, which is one of the most useful tools available at this stage.

How to stop it here: Once a levy notice arrives, time matters more than anything else.

Requesting a Collection Due Process hearing, entering an installment agreement, or demonstrating financial hardship (Currently Not Collectible status) can all halt collection.

Waiting past the 30-day window narrows your options considerably.

The Common Thread

At every one of these stages, the IRS is required to tell you what’s happening and give you a window to act. The system is designed to be escalating, not surprising.

What changes as you move through the stages isn’t whether you can fix it, it’s how much harder and more expensive fixing it becomes, and how much of the decision-making power stays in your hands versus theirs.

If you’re staring at a notice right now, wherever it falls in this process, the best move is the same one: don’t wait for the next letter to figure out what it means. At Smith Patrick CPAs, we help clients navigate IRS notices at every stage, from a first balance due letter to active collections.
