Owe the IRS but Can't Pay? What Happens and What to Do

You filed, or you are about to file, and the number at the bottom is more than you have. Maybe a side job did not withhold tax. Maybe a retirement withdrawal came with a bigger bill than you expected. Whatever the reason, you are not the first person in this spot, and the IRS has standard ways to handle it.

The worst thing you can do is nothing. The second worst is to skip filing because you cannot pay. This guide explains what happens when a balance goes unpaid and the practical steps that keep the problem from growing.

First, file your return anyway

Not filing and not paying are two separate problems with two separate penalties, and the filing penalty is much bigger.

• Failure to file: Internal Revenue Code section 6651(a)(1) adds 5% of the unpaid tax for each month the return is late, up to 25%.
• Failure to pay: section 6651(a)(2) adds 0.5% per month of the unpaid tax, up to 25%.

So a return filed on time with no payment costs far less than a late return with no payment. Filing also matters for later: you generally must have filed all required returns before the IRS will approve a payment plan (Internal Revenue Manual, IRM 5.14.1.4.2). If you have older years that were never filed, read why to file before you ask for a payment plan.

What happens when a tax balance goes unpaid

The IRS does not seize property the day after the due date. Collection follows a series of notices and legal steps. Here is the general shape of it.

Penalties and interest keep growing

Interest runs on the unpaid balance. The underpayment rate under section 6621 is 7% for October 1 through December 31, 2026 (Revenue Ruling 2026-15). It is compounded daily under section 6622, and the rate resets every quarter. The failure-to-pay penalty adds up month by month on top of that. Both keep accruing until the balance is paid, even while you are on a payment plan (IRM 5.14.1.1.1).

The penalty rate can double

Under section 6651(d), the failure-to-pay rate rises from 0.5% to 1% per month beginning 10 days after the IRS sends a notice of intent to levy under section 6331(d). The CP504 notice is that notice. Waiting until that letter arrives costs you money.

Liens and levies

If the balance stays unpaid, the IRS can file a Notice of Federal Tax Lien, a public notice of its claim against your property. Its general filing guideline is an unpaid balance of $10,000 or more (IRM 5.12.2.6). See how payment plans interact with tax liens.

The IRS can also levy, which means legally take, wages, bank accounts and other property after the required notices. That is the step most people fear, and it is the one a payment plan request can hold off.

How asking for a plan protects you

Section 6331(k)(2) bars the IRS from levying while an installment agreement request is pending, for 30 days after a rejection (and during an appeal filed within those 30 days), while the agreement is in effect, and for 30 days after a termination (and during an appeal). The protection starts when you ask, not when the plan is approved. That is why asking early matters.

Your options, from simplest to most involved

1. Pay in full now, if you can. Borrowing from a lower-cost source can make sense when it costs less than IRS interest and penalties. Do the math before you decide.
2. Short-term payment plan. If you can pay everything within 180 days, the IRS can give you that time with no setup fee (IRM 5.19.1.6.3). See IRS short-term payment plans.
3. Simple Payment Plan. If you owe $50,000 or less in combined tax, penalties and interest, you can usually get a monthly plan without filling out a financial statement (IRM 5.14.5.2). This used to be called a streamlined installment agreement. See Simple Payment Plans.
4. Guaranteed installment agreement. If your income tax owed is $10,000 or less and you meet the other conditions in section 6159(c), the IRS must accept your plan. See guaranteed installment agreements.
5. Larger plans. Over $50,000, the IRS may ask for financial information and closer review. See how larger payment plans work.
6. Partial payment plan. If you can pay something each month but not enough to finish before the collection deadline, a partial payment installment agreement may fit (IRM 5.14.2). See partial payment installment agreements.
7. Currently not collectible status. If paying anything would leave you unable to cover reasonable basic living expenses, the IRS can treat the account as a hardship (IRM 5.16.1.2.9). See currently not collectible status.
8. Offer in compromise. In some cases the IRS will settle for less than the full amount under section 7122. See offer in compromise or payment plan.

What to do this week

1. File every return that is due, even if you cannot pay with it.
2. Pay what you can now. Every dollar paid today stops interest and penalties on that dollar.
3. Find out your total balance, including penalties and interest. Your most recent notice lists it, or you can call the number on the notice and ask for a current payoff figure.
4. Pick the plan that fits and ask for it. Many plans can be set up online. See how to apply for an IRS payment plan.
5. Fix the cause going forward. Adjust withholding or start estimated payments. You must stay current on new taxes to qualify for a plan and to keep it (IRM 5.14.1.4.2; IRM 5.14.11.3).
6. Open every IRS letter. Some carry deadlines that protect important rights.

What it will cost

Payment plans have setup fees that depend on how you apply and whether you pay by direct debit. Applying online with direct debit costs $29 under the fee schedule effective July 5, 2026 (IRM 5.14.1.2). Short-term plans have no fee. Fees can change, so confirm on IRS.gov. Details are in what an IRS payment plan costs.
