What Happens When Unpaid Taxes Go to Collections?

When federal taxes go unpaid and the account moves into collections, the IRS starts a structured process: a series of written notices, a growing balance from penalties and interest, and eventually enforcement actions like liens, levies, and, in some cases, assignment to a private collection agency. You have time to act between each stage, and every resolution option available to you works better the earlier you use it.

The Notice Sequence That Starts It All

Within 60 days of assessing a tax you haven’t paid, the IRS is required to send you a written notice stating the amount owed and demanding payment.¹ The first letter is usually a CP14, which shows the total balance including penalties and interest already added.² Pay by the date on that notice and no further interest is added.

Ignore it, and follow-up notices arrive at roughly five-week intervals. The CP501 is a first reminder.³ The CP503 is a second reminder that warns of more penalties and interest if you don’t respond.⁴

The one you cannot ignore is the CP504, titled “Notice of Intent to Seize Your Property.” It gives you 30 days to pay, arrange a payment plan, or request a hearing before the IRS can levy your state tax refund and move toward taking other assets. When those 30 days pass, the agency has legal authority to start seizing property.

How the Balance Grows While You Wait

Two charges run at the same time on an unpaid tax balance, and interest applies to the penalties themselves. That compounding is why balances grow faster than people expect.

The failure-to-pay penalty is 0.5% of the unpaid tax for each month or partial month it remains outstanding, capped at 25% of the original amount owed. If the IRS issues a notice of intent to levy and you still haven’t paid after 10 days, the rate doubles to 1% per month. Setting up an installment agreement cuts the rate to 0.25% per month while the agreement is active.⁵

Interest is set quarterly at the federal short-term rate plus three percentage points. The rate was 7% for the first quarter of 2026⁶ and dropped to 6% for the second quarter.⁷ It compounds daily. Paying any amount now, even a partial one, slows the growth.

Federal Tax Liens

A federal tax lien is the government’s legal claim against your property. It arises automatically once the IRS assesses the tax, sends a demand for payment, and you don’t pay.⁸ It attaches to everything you own and anything you acquire afterward, including real estate, vehicles, and financial accounts.

A lien is not a seizure. It establishes the government’s priority ahead of other creditors. In practice, it can appear on your credit report, block a sale or refinance of property, and complicate business dealings. The lien remains until you pay the debt in full, the collection deadline expires, or you settle with the IRS.

Levies, Wage Garnishment, and What’s Protected

A levy is the actual seizure. Ignore the IRS long enough and the agency can take money from your bank accounts, garnish your wages, or seize physical property such as vehicles or equipment and sell it at auction.⁹ A wage levy is continuous: it keeps pulling from each paycheck until the debt is paid or the levy is released.

Before levying, the IRS must send a written notice at least 30 days in advance describing the proposed seizure and your right to a hearing.¹⁰ That 30-day window is your last clean opportunity to request a Collection Due Process hearing, arrange a payment plan, or otherwise resolve the debt.

Federal law shields certain property from levy. For 2026, the protected categories and dollar limits include:¹¹

Household goods and personal effects up to $11,980 in value¹²
Tools of your trade or profession up to $5,990 in value¹²
Unemployment and workers’ compensation benefits, fully exempt
Certain pension and disability payments, including Social Security disability, service-connected VA disability, and Railroad Retirement benefits
Any income needed to comply with a court-ordered child support obligation
Your primary residence, which can only be seized if the tax debt exceeds $5,000 and a judge approves the seizure
A minimum amount of wages: the IRS must leave you enough weekly income to cover your standard deduction and dependent allowances (roughly $310 per week in 2026 for a single filer with no dependents)

When a Private Collection Agency Takes Over

Federal law requires the IRS to assign certain inactive tax debts to private collection agencies.¹³ An account typically gets assigned after the IRS has run through its notice cycle and either can’t reach you or lacks the staff to keep working the case.

These contractors operate under tight limits. They can contact you, request payment, and offer installment agreements covering the full balance for up to seven years.¹³ They cannot seize assets, garnish wages, or issue a legal summons. A caller claiming to represent the IRS who threatens any of that is running a scam.

Not every account is eligible. The Taxpayer First Act bars the IRS from assigning debts belonging to taxpayers with adjusted gross income at or below 200% of the federal poverty level. Taxpayers receiving Social Security disability benefits and those in designated disaster areas are also protected from assignment.

Before any private agency contacts you, the IRS sends a written Notice CP40 to your last known address confirming the transfer to a specific collector. The agency then sends its own follow-up letter. Legitimate correspondence includes a unique taxpayer authentication number you can use to verify the caller. Payments always go to the U.S. Treasury; a request to pay by wire transfer, gift card, or cryptocurrency is fraud.¹⁴

The 10-Year Collection Deadline

The IRS has 10 years from the date a tax is assessed to collect the balance. That deadline is the Collection Statute Expiration Date, or CSED.¹⁵ Once it passes, the debt is legally uncollectible.

The clock does not always run continuously. Several events pause it and extend how long the IRS has to collect:¹⁶

Bankruptcy pauses the clock while the case is pending and adds six months after it concludes.
A pending offer in compromise appeal pauses the clock.
A Collection Due Process hearing suspends the collection period until the determination becomes final, including any court appeals.
An appeal of a rejected or terminated installment agreement pauses the clock while the appeal is open.

People sometimes outsmart themselves here. Filing for bankruptcy or requesting a CDP hearing buys time up front but extends the IRS’s collection window on the back end. If you are close to the 10-year mark, any of these actions can add months or years. A tax professional can calculate your actual CSED before you take a step that resets it.

Options for Resolving the Debt

Every option below is better than letting the balance grow while the IRS escalates.

Installment Agreements

An installment agreement lets you pay the full balance over time in monthly payments. Setup fees depend on how you apply and how you pay:

Online application with direct debit: $31
Online application with other payment methods: $149
Paper or phone application with direct debit: $107
Paper or phone application with other payment methods: $225
Low-income taxpayers (income at or below 250% of the poverty line): $43

Interest and the failure-to-pay penalty continue to accrue during the agreement, but the penalty rate drops from 0.5% to 0.25% per month while the plan is active.5 If your account has been assigned to a private collector, that agency can offer installment agreements running up to seven years.¹³

Offer in Compromise

An offer in compromise lets you settle for less than the full amount if the IRS agrees you can’t realistically pay it all. The application fee is $205, and you’ll typically need to include an initial payment with the offer.¹⁷ Low-income taxpayers who meet the certification guidelines are exempt from both. The IRS weighs your income, expenses, assets, and ability to pay. Most offers are rejected, so this is not a shortcut. It is genuinely for people who cannot pay.

Currently Not Collectible Status

If paying anything toward the debt would prevent you from covering basic living expenses like housing, food, and utilities, you can ask the IRS to place your account in Currently Not Collectible (CNC) status.¹⁸ CNC is not forgiveness. The debt still exists, interest and penalties keep accruing, and the IRS can still file a lien. But active collection stops, including levies and phone calls. The IRS reviews CNC accounts periodically and can reactivate collection if your finances improve. If the CSED expires while you’re in CNC status, the debt goes away.

Appealing a Lien or Levy

You can push back on collection actions through two different processes.

Collection Due Process Hearing

After the IRS files a federal tax lien or sends a final notice of intent to levy, you have 30 days to request a Collection Due Process hearing using Form 12153.¹⁰ A timely request stops the IRS from levying while the hearing is pending.¹⁹ In the hearing you can propose alternatives such as an installment agreement or offer in compromise, challenge whether the IRS followed proper procedures, and in some cases dispute the underlying tax liability. If you disagree with the outcome, you can take the case to the U.S. Tax Court. Miss the 30-day window and you can still request an “equivalent hearing,” but you lose the right to go to court and the IRS does not have to stop collection while it’s pending.

Collection Appeals Program

The Collection Appeals Program (CAP) is faster and more informal. File Form 9423 and an Appeals officer reviews whether the IRS’s proposed lien, levy, or seizure was appropriate.²⁰ The trade-off for speed: CAP decisions are final, with no right to judicial review, and you can’t use CAP to propose alternative collection options the way a CDP hearing allows. CAP fits when you need a quick decision and are confident the action itself was improper. For most people, the CDP hearing is the stronger tool.
