How a Seven-Figure IRS Assessment Ends in Currently Not Collectible Status

When a taxpayer stops filing, the IRS builds returns of its own, assesses tax on them, and starts collecting. The number that process produces is almost always worse than a real return would have produced, and by the time most people open the notice the assessment is already on the books.

This is how one of those cases was worked: a seven-figure assessment against a business owner from Alabama, built entirely from substitute returns, resolved through Currently Not Collectible status rather than a payment plan or a settlement offer.

The situation

The client was a business owner from Alabama working in the contracting trades. He had not filed personal returns for many years across multiple tax periods. The IRS did what it does when returns stop arriving but income documents keep coming: it prepared substitute returns and assessed tax on them. The resulting liability ran into seven figures.

By the time the case came in, the assessments were final, the notices had gone out, and the account was moving toward enforced collection.

Why a substitute-return assessment is more serious than it looks

The IRS is candid about what a substitute return is. In its own words, “if you fail to file, we may file a substitute return for you” — and that return “might not give you credit for deductions and exemptions you may be entitled to receive.” For a self-employed contractor, that is the whole problem. Gross receipts reported on 1099s become income. Materials, subcontractor payments, vehicle costs, insurance and every other cost of doing the work do not become deductions, because nobody claimed them.

So the assessment is not a measure of what was owed. It measures what third parties reported, taxed as though it were profit. Across several years, with failure-to-file and failure-to-pay penalties and accrued interest on top, a modest contracting business produces a liability that looks nothing like the business behind it.

Two consequences follow. First, the balance is collectible — a substitute-return assessment is a real assessment, and the IRS can levy on it. Second, the clock has already started. Under IRC § 6502, the IRS generally has ten years from the date of assessment to collect. The Internal Revenue Manual states the rule plainly: “the length of the period for collection after assessment of a tax liability is 10 years.” Each year’s assessment carries its own Collection Statute Expiration Date, or CSED.

The options, and why this route

Three routes are normally on the table.

Filing original returns to replace the substitutes. The IRS invites this: “If the IRS files a substitute return, it is still in your best interest to file your own tax return to take advantage of any exemptions, credits and deductions you are entitled to receive. The IRS will generally adjust your account to reflect the correct figures.” Where records survive, this is the first thing to do, because it attacks the number itself rather than the collection of it.

An installment agreement. Workable when the balance bears some relationship to what the taxpayer can pay. Against a seven-figure substitute-return assessment and a small contracting income, it does not.

Currently Not Collectible status. This is the route the case took. CNC does not reduce the assessment and does not settle anything. What it does is stop active collection while the taxpayer cannot pay — and, critically, it is not one of the events that suspends the collection statute. The ten-year clock on each assessment keeps running in the background.

How Currently Not Collectible status actually works

Step one: get into filing compliance

The IRS will not place an account into a collection alternative while returns are missing. Delinquent returns come first, which in a substitute-return case means preparing original returns for the open years and submitting them against the existing assessments. Where records support it, this step alone can move the balance before any collection argument is made.

Step two: build the collection information statement

CNC is a financial determination, and the IRS makes it from a collection information statement. Depending on the taxpayer, that is Form 433-F, Form 433-A (wage earners and self-employed individuals), or Form 433-B (businesses). The IRS notes it “may also request documents verifying income, expenses, bank accounts, and assets.” Expect to produce bank statements, pay records, and proof of every expense claimed.

This part is won or lost on preparation. Unsupported expense figures get reduced, and a reduced expense figure produces an ability to pay the taxpayer does not have.

Step three: the hardship test against the financial standards

The IRS measures the statement against its Collection Financial Standards, which it describes as tools “used to help determine a taxpayer’s ability to pay a delinquent tax liability” by setting allowable living expenses at what is “necessary to provide for a taxpayer’s (and his or her family’s) health and welfare and/or production of income.” The standards cover four areas: national standards for food, clothing and personal care; national standards for out-of-pocket health care; local standards for housing and utilities, which vary by county; and local standards for transportation.

Allowable expenses are subtracted from income. If what remains cannot service the debt without leaving the taxpayer unable to meet basic living expenses, the account qualifies for a temporary delay in collection.

Step four: understand exactly what CNC does and does not do

The IRS is direct about the limits. On CNC accounts it has “temporarily suspended most collection activities” — but “you still owe the full amount of your tax debt. It is not forgiven or cancelled.” Two further points matter and are frequently missed:

• “Penalties and interest continue to accrue until you pay your balance in full.” The balance grows while the account sits in status.
• “We may file a Notice of Federal Tax Lien to protect the government’s interest in your property.” CNC stops levies and garnishment; it does not stop a lien.

Step five: the collection statute keeps running

This is the mechanism that carried the case. IRC § 6503 and the Internal Revenue Manual list the events that suspend or extend the collection period: bankruptcy, litigation, a pending offer in compromise, a timely Collection Due Process hearing request, certain installment agreement periods, a continuous absence from the United States of at least six months, and combat zone service. Currently Not Collectible status is not on that list.

That asymmetry is the point. An offer in compromise suspends the clock “while the offer is pending with the IRS,” plus the appeal window; a CDP request suspends it until the determination becomes final. CNC does neither. Collection pauses; the statute does not.

Step six: stay in status

CNC is not permanent and is not left alone. The IRS says it “may review your financial situation later” and “may resume collection if your ability to pay improves.” Income above a threshold set when the account is closed into status triggers a review, which can pull the account back into active collection.

So representation on a CNC case is not a one-time filing. It means holding the status through each review with current documentation, keeping later years filed and current so a new balance does not reopen the file, and tracking each year’s CSED so the endpoint is known rather than hoped for.

What changed for the client

The account went into Currently Not Collectible status and stayed there. Active collection stopped. The oldest substitute-return assessments reached their collection statute expiration dates while the account sat in status, and the liability attached to those years came off the books. What remained was small enough to address through an ordinary installment agreement.

CNC status does not guarantee that a liability expires; it creates the conditions under which the statute can run while collection is paused. Whether any account qualifies, how long it holds, and what remains depend entirely on the taxpayer’s facts and the IRS’s determination.

If you are in a similar position, start here

1. Pull your account transcripts. They show what was assessed, for which years, and on what date. The assessment date sets each year’s CSED.
2. Find out whether the assessments are substitute returns. If they are, filing original returns for those years may reduce the balance before any collection argument is needed.
3. Do not ignore a Notice of Deficiency. If you receive a CP3219N, the IRS gives you “90 days to file your past due tax return or file a petition in Tax Court.” That window does not reopen.
4. Assemble your financials first. Income, living expenses, assets and the documentation behind each. Whether the conversation ends in an installment agreement, an offer, or CNC, it starts with the same statement.
5. Get representation before enforced collection starts. Options are wider before a levy than after one.
