IRS CIO: Centralized Insolvency Operation, Claims, Discharge

The IRS Centralized Insolvency Operation, known as the CIO, is the single Philadelphia office that handles federal tax matters in nearly every bankruptcy case. If you’ve filed, or your attorney or trustee is dealing with the IRS on your case, this is the unit on the other end. Its general phone line is 800-973-0424, and payments and correspondence go to P.O. Box 7317, Philadelphia, PA 19101-7317.¹

What the CIO Handles Once You File

The bankruptcy court’s electronic notice system alerts the CIO the moment a petition is filed. From there, CIO staff take over the government’s role as a creditor: they review your tax account, calculate what you owe with penalties and interest, file the government’s formal proof of claim, flag your account so IRS collection systems stop, coordinate with the trustee on payments, respond to court orders, and handle lien releases after the case closes.

The point of centralization is that you, your attorney, or the trustee route almost everything through one unit rather than chasing local IRS offices. That should mean faster and more consistent answers, but it also means the CIO is a single choke point, and getting your file matched to the right notice matters.

What Stops and What Doesn’t Stop

Filing the petition triggers the automatic stay under federal law. New levies, wage garnishments, and property seizures all have to stop while the case is open.² CIO employees flag your account in IRS systems so automated collection halts. A willful violation of the stay entitles you to actual damages, including attorney fees, and in some cases punitive damages.³

What the stay doesn’t do is freeze every IRS interaction. The agency can still:

Audit your returns and determine your correct liability.
Issue a notice of tax deficiency if an audit turns up more tax due.
Demand any returns you haven’t filed.
Assess a tax and send a notice demanding payment. Any resulting lien generally won’t attach to estate property unless the debt is nondischargeable.⁴

So the IRS can figure out what you owe and tell you about it. It generally can’t take your money or property to collect while the stay is in effect.

The Proof of Claim

Once the CIO confirms your filing, it calculates your total tax debt and files a proof of claim with the bankruptcy court. This is the government’s formal statement of what the estate owes.⁵ The government has 180 days after the order for relief to file, longer than private creditors get.⁶

The CIO sorts each tax debt into one of three categories, and the category decides when and whether you pay:

Secured claims are backed by a federal tax lien on property you own. The secured portion equals the value of the property the lien attaches to; any excess is treated as unsecured.⁷
Priority unsecured claims must be paid in full through the plan even without a lien. These include income taxes due within three years before filing and taxes assessed within 240 days before filing.⁸
General unsecured claims are older tax debts that don’t qualify for priority. They’re treated like credit card debt and may receive partial payment, or nothing.

Classification is where most of the money moves. A tax debt tagged priority has to be paid in full under a Chapter 13 plan. The same debt tagged general unsecured might be discharged entirely.

If the CIO’s Numbers Look Wrong

The IRS doesn’t always get it right. Penalties may sit on the wrong balance, interest may have compounded through a period you already paid, or a dischargeable debt may be listed as priority. Once filed, the proof of claim is treated as valid unless someone objects.

You or your attorney file the objection with the bankruptcy court and serve it on the IRS at least 30 days before the hearing. Because the IRS is a federal agency, service has to follow the special procedures for government entities.⁹ The bankruptcy court has broad authority to determine the amount or legality of any tax, even one the IRS has already assessed.¹⁰ It’s one of the few places outside the Tax Court where you can push back on the IRS’s numbers, and catching an error early can save thousands over the life of a repayment plan.

Which Tax Debts Actually Go Away

Not every tax debt survives bankruptcy, and not every one can be wiped out. For income taxes, all of the following have to be true for the debt to be dischargeable:

The return was due, including extensions, more than three years before you filed the petition.⁸
If you filed the return late, you filed it at least two years before the petition date.¹¹
The IRS assessed the tax more than 240 days before you filed. A pending offer in compromise and certain other events can extend that window.⁸
You actually filed a return. Taxes for which no return was ever filed can’t be discharged.
There was no fraud or willful evasion. A fraudulent return or a deliberate dodge stays with you regardless of timing.¹¹

Some categories are never dischargeable. Withholding and trust fund taxes that you collected from employees but didn’t pay over survive any chapter, and so do taxes that come due after you file.¹²

Returns You Still Have to File

Bankruptcy doesn’t pause your obligation to file returns or pay current taxes. This is where cases collapse most often, and the CIO watches compliance closely.

Under Chapter 13, you have to submit all federal tax returns for taxable periods ending in the four years before your petition, and they have to be filed before the first meeting of creditors.¹³ Miss that and you can lose plan confirmation or the whole case.

Throughout the case, whatever chapter you filed under, keep filing returns on time and paying new taxes as they come due. Falling behind on post-petition taxes is one of the most common reasons cases get dismissed.¹⁴ And because post-petition tax debts can’t be discharged, a dismissed case leaves you owing both the new taxes and whatever was left of the old ones.

If you have unfiled returns, the CIO can’t prepare an accurate proof of claim and may estimate your liability, which almost always runs higher than what a properly filed return would show. Getting returns in before or right after your petition is one of the highest-value moves you can make.

Liens That Outlive the Discharge

A discharge eliminates your personal obligation to pay certain tax debts, but it does not automatically remove a federal tax lien that was recorded against your property before the case was filed. The discharge works as an injunction against collecting from you personally; a lien that already attached to specific property can still ride along on that property.¹⁵

The IRS can still enforce that lien against the property itself, and it will show up in any title search if you try to sell or refinance.¹⁶ To clear the title, you’ll need to work with the CIO. Send a copy of your final discharge order and any court orders addressing the lien. The CIO reviews whether the underlying debt was discharged or whether the lien remains enforceable, and files a certificate of release with the local recording office if appropriate. This part rarely happens on its own, so plan to start it yourself.

Reaching the CIO

The CIO’s general phone line is 800-973-0424. Chapter 7 and Chapter 13 payments go to P.O. Box 7317, Philadelphia, PA 19101-7317. Physical mail can also go to 2970 Market Street, Philadelphia, PA 19104-5016, directed to the Payment Team at Mail Stop 5-Q30-133.¹

A separate fax line, 844-250-2035, is reserved for prompt determination and prompt refund packages only. Sending anything else there risks delay.¹⁷ Electronic filing through the court’s system generally updates IRS records faster than mailing paper.

Before you call, have your bankruptcy case number, the chapter, the petition date, and your Social Security number or EIN in front of you. If you previously requested a collection due process hearing using Form 12153, say so, because it affects how the CIO handles your account.¹⁸
