Cancellation of Debt: How To Fight a 1099-C in Tax Court

A 1099-C landed and the IRS says you owe tax on a debt you never paid back. It doesn't have to. Insolvency and § 108 can take that bill to zero.

A Form 1099-C landed in your mailbox—or a CP2000 says you owe tax on cancelled debt—and it reads like a settled bill. The credit card company, the bank, or the mortgage lender wrote off what you owed, and now the IRS wants tax on money you never actually received. It feels backward, and it feels final.

It is neither. Here is the reassuring truth that runs through this whole article: a 1099-C does not automatically mean you owe the tax. Cancelled debt is income by default, but the law is full of exits—and the biggest one, insolvency, can reduce that income or zero it out completely. A great many consumer 1099-Cs end with no tax at all once you run the numbers. The catch is that none of it is automatic. You have to claim the exclusion on Form 982 and prove you qualify. A 1099-C is the start of the analysis, not the end of it.

This is the substantive merits guide to fighting cancellation-of-debt (COD) income under IRC § 108. It is a deep companion to Unreported Income Disputes in Tax Court, which owns the general 1099-matching machinery, the § 6201(d) information-return burden shift, and the broader unreported-income picture. This article does not re-teach those—it goes deep on COD specifically: the 1099-C box by box, the insolvency worksheet, the recourse-versus-nonrecourse foreclosure trap, the year-by-year currency on home and student-loan discharges, and the honest cost of claiming an exclusion.

The Default Rule: Cancelled Debt Is Income

Start with where the law starts. IRC § 61(a)(11) lists "income from discharge of indebtedness" as gross income. When a creditor releases you from a debt, you are richer than you were—you have money you would otherwise have had to hand over—and the Code treats that as an accession to wealth.

The idea is almost a century old. In United States v. Kirby Lumber Co., 284 U.S. 1 (1931), a company issued bonds at par and later bought some back for less than face value; the Supreme Court held the difference was taxable gain, because the company "made a clear gain" and "realized within the year an accession to income". Being freed from a debt for less than you owed is, in the eyes of the tax law, the same kind of gain.

One quick note on the citation, because old cases look different. The correct cite today is § 61(a)(11). Every COD case and regulation written before the 2017 Tax Cuts and Jobs Act says "§ 61(a)(12)"—and that was correct then. TCJA struck an earlier paragraph and renumbered the list, so the old (12) became today's (11). When you read an older opinion or even Treasury Regulation § 1.1001-2 still citing "(a)(12)," that is correct history for that text, not a mistake to copy. For anything you write now, the section is § 61(a)(11).

So § 61(a)(11) is the default. But it is only a default. § 108 is a long list of exits, and the rest of this guide is about finding yours.

What a Form 1099-C Actually Is—Box by Box

A creditor files Form 1099-C when an "identifiable event" tells the IRS a debt was cancelled (Reg. § 1.6050P-1). You typically receive your copy early in the year after the discharge—like a W-2, by late January or February—and a matching CP2000 notice, if one comes, usually lands a year or more after that. The form is not a tax bill and not a finding that you owe anything—it is an information return, and every box on it is something you can check and, where wrong, dispute.

Box 1 — Date of Identifiable Event. The date the creditor says the debt was cancelled. This sets the tax year. Verify it: a wrong year is a common and winnable issue (more below).
Box 2 — Amount of Debt Discharged. The cancelled amount. Per the IRS instructions, it cannot be greater than the total debt minus anything the lender received in a settlement, foreclosure sale, or short sale. Check Box 2 against your own records—it is frequently overstated by including fees or accrued interest, or by ignoring partial payments you made.
Box 3 — Interest Included in Box 2. Creditors are not required to fold interest into Box 2, but if they did, they must break it out here. This matters: an inflated Box 2 may be partly accrued interest. (And interest that would have been deductible if you had paid it is not COD income at all—see below.)
Box 4 — Debt Description. A plain label: "credit card," "student loan," "mortgage," and so on.
Box 5 — "Check Here if the Debtor Was Personally Liable." This is the recourse flag, and for anyone whose debt was secured by property it is the single most consequential box on the form. Checked means recourse (you were personally on the hook). Unchecked means nonrecourse. It controls the entire foreclosure analysis below.
Box 6 — Identifiable Event Code (A–H). The reason code (full list next).
Box 7 — Fair Market Value of Property. Used when a 1099-C accompanies a 1099-A for a foreclosure or repossession—generally the foreclosure bid price or appraised value. Box 7 against Box 2 is what splits a recourse foreclosure into its two pieces.

The Identifiable-Event Codes (Box 6)

Code	Event
A	Discharge in bankruptcy under Title 11
B	Cancellation that makes the debt unenforceable in a receivership, foreclosure, or similar proceeding
C	Statute of limitations expires—but only after your SOL defense is upheld in a final court judgment
D	Creditor elects foreclosure remedies that by law bar further collection
E	Cancellation that makes the debt unenforceable in a probate or similar proceeding
F	Agreement between creditor and debtor to cancel for less than full payment—short sales and negotiated settlements; the most common consumer code
G	Creditor's decision or defined policy to stop collection and cancel
H	Other actual discharge before an identifiable event

One trap worth flagging: many people assume an old, time-barred debt automatically produces a Code C 1099-C. It does not. The instructions are explicit that a lapsed statute of limitations is an identifiable event only once a court has upheld your SOL defense in a final judgment. The IRS's position is that a statute of limitations bars the remedy, not the debt—so a time-barred-but-never-adjudicated debt is not yet "discharged" for COD purposes. (For the limitations background generally, see Understanding IRS Statutes of Limitations.)

Two Things a 1099-C Does Not Prove

Courts have settled two points that matter enormously to anyone holding a 1099-C they think is wrong.

First, a 1099-C is not conclusive that the debt was discharged at all. A creditor's internal bookkeeping entry does not, by itself, create COD income. The Tax Court has repeatedly said the issuance of a 1099-C is an identifiable event but is not dispositive of an intent to cancel the debt—a proposition drawn from Owens v. Commissioner, T.C. Memo. 2002-253 and applied in Newman v. Commissioner, T.C. Memo. 2016-125 and Kleber v. Commissioner, T.C. Memo. 2011-233. A debt is genuinely discharged "the moment it becomes clear that the debt will never be repaid" (Cozzi v. Commissioner, 88 T.C. 435 (1987), at 445)—a facts-and-circumstances question, not a clerk's date. (Owens is a fee-recovery case in which the IRS had already conceded the underlying deficiency; cite it for this narrow "not dispositive" point only.)

Second, a 1099-C is not conclusive of the year. The year you realize COD income is a question of fact. If the real discharge happened earlier, the income belongs to that earlier year—which may now be closed by the assessment statute under IRC § 6501, barring the IRS from taxing it at all. In Kleber, a $263,587 1099-C issued for 2006 produced no 2006 income because the discharge had actually occurred years earlier, and the IRS could not prove otherwise. The taxpayers were represented and won outright. Use these cases as the authority you rely on—they establish the rule, even though they were not pro se cases.

A currency note that prevents a real mistake. You may read that going 36 months without a payment automatically triggers a 1099-C. That rule is gone. Treasury Decision 9793 (final regulations, November 2016) removed the 36-month nonpayment testing period as an identifiable event, effective for 1099-Cs filed after December 31, 2016, because it confused taxpayers into reporting income while the creditor was still trying to collect. Newman and Kleber both used the old 36-month presumption, but the broader principle they stand for—that a 1099-C is rebuttable on both fact and year of discharge—fully survives. Just do not tell yourself that 36 months of silence creates the income; it does not.

What you actually do about a wrong 1099-C. You do not have to get the creditor to issue a corrected form before you can dispute it—and most creditors will not bother. You report the correct figure on your return (or in your CP2000 response), keep the proof that supports it, and attach a short explanation of why the form is wrong—the right discharge year, the real Box 2 amount net of what the lender collected, or the interest that should have been broken out in Box 3. If the creditor will issue a corrected 1099-C, that helps; if not, your records and explanation carry the dispute. The IRS does not treat the form as the last word, and neither should you.

First Move: Verify the IRS's Numbers

Before you argue the law, pin down the facts on the form. Every step here is something you can do yourself.

Confirm the Box 1 year. If the debt actually became uncollectible in an earlier year, the income may belong to that year—possibly a closed one (Kleber; § 6501).
Confirm the Box 2 amount against your records. Subtract anything the lender actually collected, and check Box 3 for accrued interest padding the number.
Confirm the Box 5 recourse flag. Checked or unchecked changes the entire analysis for any debt secured by property.
Confirm Box 7 / 1099-A fair market value for foreclosure and repossession cases. On a recourse debt, the COD piece is only the slice of debt above FMV—not the whole balance.
Pull your IRS transcripts. Your Account Transcript and Wage & Income transcript show what the IRS received and whether the COD was actually assessed. See How To Get and Read Your IRS Transcripts, and How To Read IRS Transcript Codes to spot the assessment.
Build the Pub. 4681 insolvency worksheet dated to the moment immediately before the discharge, and recompute. That worksheet is the next section—and it is the heart of the case.

The Insolvency Exclusion: Your Best Defense

For most consumer 1099-Cs, insolvency is the workhorse. The principle in § 108(a)(1)(B): cancelled debt is excluded from income to the extent you were insolvent immediately before the discharge.

"Insolvent" has a precise meaning. Under § 108(d)(3), you are insolvent by the amount your total liabilities exceed the fair market value of your total assets, measured immediately before the cancellation. And the exclusion is capped at the amount of your insolvency under § 108(a)(3)—you cannot exclude more cancelled debt than the dollar amount by which you were underwater.

Put together, the mechanic is simple:

Insolvency amount = total liabilities − fair market value of total assets (immediately before the discharge; if zero or less, you are not insolvent).
Amount excluded = the lesser of (a) the debt cancelled or (b) your insolvency amount.
Any cancelled debt above your insolvency amount is taxable COD income.

The Pub. 4681 Insolvency Worksheet

The IRS gives you the exact tool to compute this: the Insolvency Worksheet on page 7 of Publication 4681. It is your evidence—build it, dated to the day before the discharge, with statements backing every line. The worksheet has two halves.

Liabilities immediately before the cancellation include credit card debt; mortgages (main, second, or investment property, including HELOCs); car and other vehicle loans; medical bills; student loans; accrued-but-unpaid mortgage interest, real-estate taxes, utilities, and childcare; income taxes still owed from prior years; judgments; business debts; margin and investment-purchase debt; and any other liabilities.

Fair market value of assets immediately before the cancellation includes cash and bank balances; real property; vehicles; computers; household goods and furnishings; tools; jewelry; clothing; books; stocks and bonds; collectibles; firearms and hobby equipment; interests in retirement accounts (IRA, 401(k)) and pension plans; education and life-insurance cash value; security deposits; partnership and business interests; and other investments.

Subtract total asset FMV from total liabilities. That is your insolvency amount.

Do Retirement and "Exempt" Assets Count? Mostly Yes—With One Real Limit

This is the subtlest part, and the rule has two layers.

The general rule: nearly everything counts, even assets your creditors can't reach. In Carlson v. Commissioner, 116 T.C. 87 (2001), the Tax Court held that assets exempt from creditors under state or federal law are still included in the § 108(d)(3) calculation. The reasoning is that an exempt asset can still give you "the ability to pay an immediate tax" on the cancelled debt, so it counts. That is why the Pub. 4681 worksheet lists retirement and pension interests as assets. (The Carlsons were represented, and their "exempt assets shouldn't count" argument was rejected—cite the case as authority, not as a pro se win.)

The limit: an asset you genuinely cannot turn into cash to pay the tax may be left out. In Schieber v. Commissioner, T.C. Memo. 2017-32, the taxpayers held a CalPERS defined-benefit pension that paid only a monthly stream—they could not convert it to a lump sum, sell it, assign it, or borrow against it. Applying Carlson's "ability to pay an immediate tax" test, the court held that pension was not an asset for insolvency, because it could not be used to pay the tax immediately. That let the Schiebers exclude $293,308 of $418,596 in cancelled principal. They were represented, and they won; the IRS even conceded the penalty.

So state it honestly to yourself: a liquid IRA you can withdraw from counts at full value. A locked, annuitized, non-assignable pension stream you cannot tap may not. Most readers have ordinary, accessible assets, so the general "everything counts" rule governs—but the Schieber refinement is real, and worth knowing if a pension is what stands between you and insolvency.

A Worked Insolvency Example

Numbers below are illustrative, not authority—but they show how the whole thing fits together.

Maria gets a 1099-C: Box 2 is $18,000 (a credit-card settlement, Code F), Box 5 checked (recourse, unsecured—no property, so no foreclosure piece). Immediately before the discharge, her picture looked like this:

Liabilities (before discharge)		Assets at FMV (before discharge)
Credit cards	$26,000	Bank accounts	$1,200
Car loan	$9,000	Car	$7,500
Past-due state tax	$3,000	Household goods	$2,000
Medical bills	$4,000	Clothing	$800
		Accessible IRA	$11,000
Total liabilities	$42,000	Total asset FMV	$22,500

Insolvency = $42,000 − $22,500 = $19,500. Because her insolvency ($19,500) is greater than the $18,000 cancelled, all $18,000 is excluded—Form 982, line 1b, with $18,000 on line 2. Maria has no NOLs or carryovers, so the only attribute she reduces is the basis of her property (more on that cost below), which is immaterial for her. Net tax on the 1099-C: $0.

Now the honest contrast. Suppose Maria's assets had been $30,000 instead, leaving her insolvent by only $12,000. She could exclude $12,000—but she would owe tax on the remaining $6,000 of cancelled debt. And on that taxable slice, the exposure is not just the income tax: the IRS can add the 20% accuracy penalty under § 6662, and interest runs from the original due date of the return, compounding the whole time. A $6,000 taxable amount at a 22% bracket is roughly $1,320 of tax, a possible $264 penalty, plus running interest. Insolvency is what stands between the full number and zero.

A note for married readers. Insolvency is measured for the person liable on the cancelled debt. If only one spouse was on the forgiven debt, that spouse's insolvency is what counts—you generally build the worksheet from that spouse's own separate assets and liabilities, plus their share of any jointly held items, not the whole household's combined balance sheet. (And if the debt was entirely your spouse's and you filed jointly, innocent spouse relief may be a separate path worth examining.)

Proving It Is Your Job

One sentence to carry with you: insolvency is an exclusion you have to prove. Once discharge in the year is established, the burden is on you to show you were insolvent and by how much—it is "a question of fact" (Newman). The encouraging part is how that case came out: the court accepted Newman's credible testimony about his assets and liabilities without exhaustive documentation, and let him exclude the full $7,875 because he was insolvent by $14,500. If your snapshot is a decade old and the statements are gone, that is meaningful precedent—but the safe approach is still to build the worksheet with every statement you can find.

The Other Exits—And the Two That Expire by Year

Insolvency is the most common exclusion, but § 108(a)(1) lists several, and a couple turn entirely on what year your debt was discharged. Find the discharge year first.

Bankruptcy (§ 108(a)(1)(A)). A discharge in a Title 11 bankruptcy case is excluded—and it trumps everything. Under § 108(a)(2), if the cancellation happened in bankruptcy, you use bankruptcy and the other exclusions do not apply. Form 982, line 1a.

Qualified principal residence indebtedness (QPRI)—a high-stakes, year-split item. § 108(a)(1)(E) excludes cancelled mortgage debt on your main home—but only for discharges before January 1, 2026, at a cap of $750,000 ($375,000 if married filing separately) under § 108(h)(2). Pub. 4681 (2025) states it plainly: QPRI cannot be excluded for discharges completed, or discharge agreements entered into, after December 31, 2025. So split your guidance by year:

A home-mortgage discharge in 2021–2025 can still use QPRI (Form 982, line 1e), subject to the $750,000 / $375,000 cap.
A discharge in 2026 or later generally cannot—absent further legislation, the QPRI reader falls back on insolvency or bankruptcy. QPRI has been extended many times since 2008, and could be again, so check current law before relying on either side of this line. But as of now it has not been extended, which makes insolvency the central defense for a 2026 home-loan discharge.

Student-loan discharge (§ 108(f))—also split by year. The broad 2021–2025 rule (from the American Rescue Plan) that excluded most student-loan cancellations for almost any reason has sunset. OBBBA (Pub. L. 119-21) rewrote § 108(f)(5) for discharges after December 31, 2025, leaving only death and total-and-permanent-disability discharges excluded (now permanent, and requiring the borrower's Social Security number on the return). So a loan discharged 2021–2025 for almost any reason was excluded; a loan discharged 2026 or later for a reason other than death or disability is taxable COD unless another § 108 exit—insolvency, again—applies. The longstanding rule for discharge tied to working in a qualifying profession (§ 108(f)(1)) survives regardless.

Farm and real-property-business debt. § 108(a)(1)(C) (qualified farm indebtedness) and § 108(a)(1)(D) (qualified real property business indebtedness) are narrower exclusions for active farmers and certain non-corporate business owners. They sit at the bottom of the ordering rules—insolvency applies before them.

The ordering, in short. Bankruptcy first. Then, for a home discharge that also qualifies as QPRI, QPRI applies by default—but you may elect into insolvency instead under § 108(a)(2)(C), which is often the better choice because insolvency usually costs you fewer tax attributes than QPRI's mandatory reduction of your home's basis. Then insolvency. Then farm and real-property-business debt. Which brings us to the cost of excluding at all.

Foreclosure and Repossession: Recourse vs. Nonrecourse

If your 1099-C arrived because the bank foreclosed on a house or repossessed a car, there is a two-step that trips up taxpayers, software, and even lenders—and it is driven entirely by Box 5. When property securing a debt is taken or surrendered, there can be two separate tax items: gain or loss on the disposition under § 1001, and COD income under § 61(a)(11). Which ones you get depends on whether the debt was recourse or nonrecourse.

Nonrecourse debt (Box 5 unchecked) → no COD income; it is all § 1001. Because you were never personally liable, the law treats the full outstanding debt as your amount realized on the disposition—even if the debt exceeds the property's value. There is no separate COD piece. The Supreme Court settled this in Commissioner v. Tufts, 461 U.S. 300 (1983): on disposition of property securing a nonrecourse debt that exceeds fair market value, "the fair market value of the property is irrelevant"—the full debt is the amount realized. Treasury Regulation § 1.1001-2, Example 7, runs the math: a nonrecourse note of $19,000 on property worth $15,000 with a basis of $16,500 yields an amount realized of $19,000 (not the $15,000 FMV) and a $2,500 gain. No COD income.

Recourse debt (Box 5 checked) → split into two pieces. Here the amount realized on the disposition is only the property's fair market value, and the excess of the cancelled debt over FMV is COD income. Treasury Regulation § 1.1001-2(a)(2) and its Example 8 spell it out: where an asset worth $6,000 secures a recourse debt of $7,500 that is discharged, the amount realized is $6,000, and there is "income from the discharge of indebtedness of $1,500 ($7,500 − $6,000)." The gain or loss is figured on the $6,000; the $1,500 is ordinary COD income—reachable by the § 108 exclusions, including insolvency. (The regulation still cites the old "61(a)(12)," correct for its vintage.)

One more shelter on a home. If the foreclosed property was your principal residence, the § 1001 gain piece may be sheltered by the § 121 home-sale exclusion ($250,000 single / $500,000 joint), while the COD piece is handled separately by § 108 (QPRI for a 2021–2025 discharge, insolvency or bankruptcy otherwise). Two different exclusions for two different slices of the same foreclosure. When you verify a foreclosure 1099-C, check Box 5 (recourse?), Box 2 (debt), and Box 7 or the 1099-A's FMV—the recourse COD piece is only the debt-over-FMV sliver, never the whole balance.

When There's No COD Income at All

Sometimes the right answer is not an exclusion but that there was never income to begin with.

Would-have-been-deductible debt (§ 108(e)(2)). You have no COD income to the extent paying the liability would have produced a deduction. The classic example is cancelled accrued business interest: forgiving it is not income because paying it would have been deductible. This is worth checking against any Box 3 interest tied to a deductible obligation.

Purchase-price reduction (§ 108(e)(5)). If a solvent buyer's seller-financed debt is reduced by the seller (outside bankruptcy or insolvency), it is treated as a purchase-price adjustment—it reduces your basis in what you bought, not your income. This comes up in owner-financed home, car, and business sales where the seller later knocks down the balance.

Genuinely disputed debt—the contested-liability doctrine. If the amount or enforceability of the debt was genuinely disputed in good faith, settling for less may produce no COD income: the settlement is treated as fixing the true amount of the debt, and the "discount" is disregarded. The leading case is Zarin v. Commissioner, 916 F.2d 110 (3d Cir. 1990), where a gambler's $3,435,000 in casino markers—unenforceable under state law—was settled for $500,000 with no COD income, on both the contested-liability theory and the § 108(d)(1) definition of "indebtedness." But do not oversell it: the Tenth Circuit pushed back in Preslar v. Commissioner, 167 F.3d 1323 (10th Cir. 1999), limiting the doctrine to debts that are genuinely unliquidated (disputed as to amount), not a fixed balance you simply did not want to pay. The honest framing: if you disputed the amount in good faith and then settled, argue no or reduced COD—but the law is split, and a clear, fixed balance will not qualify.

Gifts. A relative's genuine forgiveness of a loan, truly intended as a gift, is excluded from your income under § 102 (it is a gift-tax matter for the lender, not income to you). No 1099-C should issue for a true gift; if one did, the defense is donative intent.

The Cost of Excluding: Form 982 and Attribute Reduction

Excluding COD income is not free, and you should know the trade-off before you are surprised by it later. Under § 108(b), the bankruptcy and insolvency exclusions are essentially a deferral: in exchange for not taxing the income now, you reduce your tax attributes, which can mean a larger tax bill down the road.

The attributes are reduced in a fixed order under § 108(b)(2): net operating losses, then the general business credit, the minimum tax credit, capital-loss carryovers, the basis of your property (via § 1017), passive-activity loss and credit carryovers, and finally foreign-tax-credit carryovers. There is a § 108(b)(5) election to reduce the basis of depreciable property first. Reducing basis means a bigger gain when you eventually sell that property.

For most consumer readers, this cost is largely theoretical. A wage earner with a credit-card 1099-C, no NOLs, and no carryovers has little to reduce—so the insolvency exclusion is nearly free, as in Maria's example. But state the cost honestly: anyone with carryforwards loses them, and anyone excluding under QPRI must reduce the basis of their home (Form 982, line 10b), increasing the gain on a future sale—which is exactly why electing insolvency instead can be better when both apply.

However you exclude, you claim it on Form 982. Form 982 is the vehicle for every § 108 exclusion: you check the box in Part I for the exclusion you are using (1a bankruptcy, 1b insolvency, 1e QPRI, and so on), put the excluded amount on line 2, and report the attribute reduction in Part II. Attach it with your insolvency worksheet as backup. No Form 982 means no exclusion claimed—which is how a fully excludable 1099-C turns into a tax bill by default.

Where the Fight Happens, and Who Proves What

The most common entry point for a 1099-C is the CP2000—the IRS's automated under-reporter notice matching the 1099-C against your return. That is the cheapest place to win: respond with your § 108 analysis and a completed Form 982 before it ever becomes a deficiency. The general CP2000 mechanics live in How To Respond to a CP2000 Notice—this article does not repeat them. (If the COD instead surfaces inside a full examination, see How To Respond to an IRS Audit.)

The usual path from there:

CP2000 arrives. Respond with the § 108 analysis and Form 982. Most COD cases should end here.
If unresolved → Notice of Deficiency (the 90-day letter). See You Just Got a 90-Day Letter From the IRS.
Petition the Tax Court within 90 days (150 days if you are outside the US) under § 6213. The filing fee is $60, with a waiver available, and the deadline cannot be extended. See How To File Your Tax Court Petition. If the deficiency for the year is $50,000 or less, you can elect small-case ("S") procedure—see Small Case or Regular Case: Which Should You Choose.
Form 982 plus the insolvency worksheet is your response vehicle at every stage. Package it per How To Prepare Your Evidence for Tax Court.
If the 90 days lapse, audit reconsideration is the fallback—you can submit the worksheet and Form 982 then too.

Already filed and paid the tax on the 1099-C? This is common—tax software often adds Box 2 to your income automatically, and a lot of people report it without knowing § 108 existed. You are not stuck. File an amended return (Form 1040-X) with Form 982 attached, claiming the exclusion and the refund, generally within the § 6511 refund window (usually three years from filing or two years from payment). See How To File an Amended Return. For an insolvent taxpayer who overpaid, this is the difference between getting the money back and never knowing it was excludable.

Most cases never reach trial. Most (76%) of Tax Court cases close by formal settlement, more than 99% resolve without a trial, and a case typically takes 6-18 months. A clean Form 982 with a backed-up insolvency worksheet often resolves a COD case at IRS Counsel without ever seeing a courtroom.

Who proves what. Two layers, and keeping them straight matters. On the income side—whether and when the debt was discharged—the IRS's determination is presumed correct (Tax Court Rule 142(a); Welch v. Helvering, 290 U.S. 111 (1933)), so you generally carry the burden to show the 1099-C is wrong. But because a 1099-C is a third-party information return, § 6201(d) can shift the burden of production to the IRS when you raise a reasonable dispute and have fully cooperated—the detailed § 6201(d) playbook lives in the unreported-income article, so use it there. On the exclusion side—insolvency and the rest—the burden is always yours. That is why the worksheet, with backup, is the case.

The COD Income Is Real but You Can't Pay

Sometimes the numbers do not save you—you were not insolvent, the year is open, and the income is genuinely taxable. Conceding is not a catastrophe, and ignoring the notice is the one move that truly makes it worse. You have options.

Currently not collectible. An insolvent taxpayer is often a strong candidate for currently not collectible status—the same facts that prove insolvency frequently prove that paying anything would leave you unable to cover basic living expenses.
Installment agreement. Pay over time with an installment agreement.
Offer in compromise. If you qualify, an offer in compromise settles the debt for less than the full amount (acceptance rates run roughly 21%).
Penalty abatement. If you accept the tax but the 20% accuracy penalty seems unfair, penalty abatement is a separate ask worth making.

The overview of all of these is in How To Resolve Your IRS Tax Debt, and as backdrop the IRS has 10 years to collect from the date of assessment.

A consumer 1099-C deficiency is usually far under the $50,000 LITC dispute cap, and a taxpayer insolvent enough to use § 108 very often falls within the 250% of the poverty line income limit. Around 89% of petitioners represent themselves, and a documentary insolvency case suits it—but the win rate is higher for represented petitioners (about 12% pro se versus about 23% represented in the most recent NTA data), so free representation is worth pursuing. Contact a Low-Income Taxpayer Clinic the day you get the letter. For a large balance, multiple years, a foreclosure with both a gain piece and a COD piece, or other complexity, see When To Get Professional Help With Your Tax Dispute.

What To Do Now

If you have a 1099-C or a Notice of Deficiency taxing cancelled debt and the 90 days clock is running:

Calendar the deadline on the face of any Notice of Deficiency. It cannot be extended.
Find the discharge year first. It drives QPRI (gone after 2025) and student-loan eligibility, and it can move the income to a closed year.
Verify the form box by box—Box 1 year, Box 2 amount, Box 3 interest, Box 5 recourse, Box 7 FMV.
Pull your IRS account transcript to confirm what was actually assessed.
Build the Pub. 4681 insolvency worksheet as of the day before the discharge, with statements backing every line.
For a foreclosure, split it: § 1001 gain (possibly § 121-sheltered on a home) versus the recourse COD piece (debt over FMV).
Complete Form 982 to claim whatever exclusion applies, and attach the worksheet.
Decide whether to petition. A timely petition preserves your prepayment forum; filing is $60, with a waiver available, and most COD cases qualify as small cases.
If you missed the 90 days, consider audit reconsideration with the worksheet and Form 982 as the new information.
Consider an LITC—you may well qualify.
