Debt conversion works by replacing an outstanding liability with a different financial instrument, most often the debtor’s own stock or a restructured debt agreement. On the debtor’s books, the old liability comes off at its carrying amount and the new instrument goes on at fair value, with the difference recognized as a gain or loss. For tax purposes, the debtor is treated as if it paid the creditor cash equal to the fair market value of what it issued, which can generate cancellation-of-debt income when that value falls short of the debt. The creditor has its own separate taxable event: gain or loss measured against its basis in the debt. Both sides need to work through the numbers before signing anything, because the accounting result and the tax result rarely match.
The Three Forms Debt Conversion Takes
Debt-to-equity is the classic case. The creditor surrenders its right to repayment and receives ownership shares instead. It shows up most often in corporate restructurings and bankruptcy, where the debtor lacks cash and equity is the next-best outcome the creditor can get.
Debt-to-debt swaps one instrument for another with different terms. A company might exchange a high-interest senior note for a lower-interest bond with a longer maturity or different collateral. This looks like ordinary refinancing, but the tax code can treat it as an exchange when the terms shift enough to be “significant.” More on that at the end.
Convertible securities are built with the conversion option at issuance. The holder decides whether and when to convert bonds or preferred stock into common stock under pre-set terms, which sets them apart from negotiated swaps. FASB’s ASU 2020-06, effective for all entities for fiscal years beginning after December 15, 2023, simplified the accounting for these instruments by eliminating the beneficial conversion feature and cash conversion models. 1Financial Accounting Standards Board. FASB Staff Issuance – Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity Under the current framework, most convertible debt sits on the balance sheet as a single liability rather than split between debt and equity components, which raises reported debt balances and lowers reported interest expense compared to the older approach.
Steps in a Debt-to-Equity Conversion
Every conversion begins with a written agreement identifying the debt being extinguished, the class and quantity of shares being issued, and the effective date. The pivotal number is the fair market value of the equity. For public companies, that’s the market price of the stock on the conversion date. Private companies generally need an independent appraisal running roughly $1,500 to $10,000 depending on complexity. Without a defensible valuation, existing shareholders, tax authorities, and regulators can challenge the transaction.
The conversion ratio follows from the valuation. Divide the face amount of the debt by the agreed per-share price. A $1,000,000 obligation converted at $10 per share produces 100,000 new shares, and every one of those shares dilutes existing owners. The dilution is worst in distressed situations, where the debt is large and the share price is low.
The board must authorize the share issuance by resolution. If the conversion would create more shares than the charter permits, the charter has to be amended first, which usually calls for a shareholder vote. Companies listed on the NYSE or Nasdaq face a further hurdle: exchange rules generally require shareholder approval before a company issues shares equal to 20% or more of its outstanding common stock, a threshold a sizeable conversion can easily cross. Public companies also have to file Form 8-K within four business days to disclose the unregistered sale of equity securities under Item 3.02. 2U.S. Securities and Exchange Commission. Form 8-K
How the Debtor Books It Under GAAP
The framework for when a liability qualifies as extinguished appears in ASC 405-20, and the measurement and reporting rules sit in ASC 470-50. Three things have to happen: the liability comes off, the new equity goes on, and any difference flows through the income statement.
A liability is extinguished when the debtor pays the creditor and is relieved of the obligation, or when the debtor is legally released from being the primary obligor. Payment can be cash, other financial assets, goods, services, or equity. Once the conditions are met, the entire carrying amount of the debt comes off the balance sheet, including principal, any unamortized premium or discount, and accrued but unpaid interest.
The new shares are recorded at fair value on the conversion date. Total fair value is split between the par value account and additional paid-in capital. When the equity’s fair value isn’t readily determinable, which is common for private companies or distressed issuers with illiquid stock, the fair value of the extinguished debt is used as the measurement basis instead.
If the fair value of the equity issued differs from the carrying amount of the debt removed, the company recognizes a gain or loss. Equity worth less than the debt produces a gain; equity worth more produces a loss. ASC 470-50-40-2 requires that gain or loss to appear as a separate item on the income statement, though companies have some flexibility: it can sit on its own line or fall within interest expense with the components disclosed in the footnotes.
Transaction costs branch two ways. Fees exchanged directly between the debtor and creditor adjust the carrying amount of the debt. Third-party costs, such as legal and advisory fees, work differently. Because debt-to-equity swaps are almost always accounted for as extinguishments (the terms are substantially different from the original), third-party costs reduce the net carrying amount of the debt and effectively raise future interest expense instead of hitting the income statement immediately.
Tax Consequences for the Debtor
The federal tax code treats a debt-to-equity conversion as if the debtor paid cash equal to the fair market value of the stock it issued. IRC Section 108(e)(8) states that when a corporation transfers stock to satisfy debt, the debt is treated as satisfied with money equal to the stock’s fair market value. 3Office of the Law Revision Counsel. 26 USC 108 – Income from Discharge of Indebtedness If the stock’s FMV is less than the debt outstanding, the shortfall becomes cancellation-of-debt income, taxable as ordinary income under Section 61. 4eCFR. 26 CFR 1.61-12 – Income from Discharge of Indebtedness
This is a paper gain with a real tax bill. The company received no cash, but a corporation reports the income on Form 1120, and at the current 21% corporate rate a $10 million gap between stock FMV and debt produces a $2.1 million liability the company has to fund from somewhere else.
Exclusions Under Section 108(a)
Two exclusions matter most in restructuring situations. If the conversion happens while the company is under the jurisdiction of a Title 11 bankruptcy court, all COD income is excluded from gross income. Outside bankruptcy, a company can exclude COD income to the extent it is insolvent immediately before the conversion, meaning its liabilities exceed the fair market value of its assets. The insolvency exclusion is capped at the amount of the insolvency: if the company is insolvent by $5 million and realizes $8 million in COD income, $5 million is excluded and the remaining $3 million is taxable. 3Office of the Law Revision Counsel. 26 USC 108 – Income from Discharge of Indebtedness
Attribute Reduction Under Section 108(b)
These exclusions defer tax rather than erase it. In exchange for excluding COD income, the debtor reduces its tax attributes, generally dollar-for-dollar, in the order set by IRC Section 108(b): 3Office of the Law Revision Counsel. 26 USC 108 – Income from Discharge of Indebtedness
- Net operating losses, current-year and carryovers, reduced dollar for dollar.
- General business credits, reduced at 33⅓ cents per dollar of excluded income.
- Minimum tax credits, reduced at 33⅓ cents per dollar.
- Capital loss carryovers, reduced dollar for dollar.
- Property basis, reduced so that future asset sales throw off larger taxable gains.
- Passive activity loss carryovers, reduced dollar for dollar; passive credit carryovers at 33⅓ cents per dollar.
- Foreign tax credit carryovers, reduced at 33⅓ cents per dollar.
The reductions apply after the current year’s tax is calculated, so the excluded income doesn’t affect that year’s return directly. But lost NOLs mean less ability to offset future income, and reduced asset basis means bigger gains when those assets sell. The downstream effect on the tax model should be mapped out before the exclusion is treated as a win.
Section 382 and Future NOLs
Even NOLs that survive the attribute reduction process can be effectively frozen by a second rule. Under IRC Section 382, an “ownership change” occurs when one or more 5-percent shareholders increase their collective ownership by more than 50 percentage points over a three-year testing period. 5Office of the Law Revision Counsel. 26 USC 382 – Limitation on Net Operating Loss Carryforwards and Certain Built-in Losses Following Ownership Change A large conversion that hands creditors a majority stake will almost certainly cross that line.
After an ownership change, the annual use of pre-change NOLs is capped at the value of the company immediately before the change multiplied by the IRS long-term tax-exempt rate. For ownership changes occurring in early 2026, that rate is 3.58%. 6Internal Revenue Service. Rev. Rul. 2026-6 A $50 million company could therefore use only about $1.79 million of pre-change NOLs per year, regardless of taxable income. For companies with large loss carryforwards, the cap can render most of those losses practically worthless.
Bankruptcy conversions get a carve-out. Under Section 382(l)(5), the annual limitation doesn’t apply if the loss corporation is in a Title 11 case and its pre-change shareholders and creditors end up owning at least 50% of the reorganized company’s stock. The carve-out has a price: pre-change losses must be reduced by the interest deductions taken on the converted debt during the three years before the ownership change, and if a second ownership change occurs within two years, the Section 382 limitation drops to zero. 5Office of the Law Revision Counsel. 26 USC 382 – Limitation on Net Operating Loss Carryforwards and Certain Built-in Losses Following Ownership Change
Tax Consequences for the Creditor
The creditor’s side is analyzed independently. Exchanging debt for stock is a taxable event: the creditor is treated as having sold the debt for the fair market value of the stock received, with gain or loss equal to the difference between that FMV and the creditor’s adjusted basis in the debt. A creditor holding a $1 million bond at face-value basis who receives stock worth $600,000 recognizes a $400,000 loss.
Character depends on whether the debt was a capital asset in the creditor’s hands, which for most investors and funds it will be. The creditor’s basis in the new stock equals its fair market value on the conversion date, and that becomes the starting point for any future sale. Individual creditors report the transaction on Form 8949 and Schedule D. 7Internal Revenue Service. Instructions for Form 8949 Whether the debtor recognizes COD income, claims an exclusion, or reduces attributes has no bearing on the creditor’s calculation. Each side stands on its own.
Two Traps in Adjacent Transactions
Related-Party Debt Acquisitions
A company can’t sidestep COD income by having a related entity buy the debt at a discount on the open market and then retire or convert it. IRC Section 108(e)(4) treats the debtor as if it directly satisfied the debt for the price the related party paid, so the discount becomes COD income to the debtor.
The reach of “related party” is wide. IRC Section 267(b) covers, among others, an individual and a corporation where the individual owns more than 50% of the stock, two corporations in the same controlled group, partnerships and corporations with more than 50% common ownership, and various trust-fiduciary-beneficiary combinations. 8Office of the Law Revision Counsel. 26 USC 267 – Losses, Expenses, and Interest with Respect to Transactions Between Related Taxpayers Constructive ownership rules pull in stock held by controlled entities on a proportional basis and treat an individual as owning stock held by siblings, spouse, ancestors, and lineal descendants.
Significant Modifications of Existing Debt
Not every change to a loan agreement triggers a tax event, but Treasury Regulation 1.1001-3 treats a “significant modification” as an exchange of the old instrument for a new one, with both sides recognizing gain or loss as if a sale had happened. 9eCFR. 26 CFR 1.1001-3 – Modifications of Debt Instruments The rule applies whether the parties issue a new instrument, amend the existing one, or accomplish the change through third-party transactions. A modification is significant when the resulting terms differ materially in kind or extent from the original: common triggers include changes to the interest rate, maturity, principal amount, or the addition of a conversion feature.
The trap sits in debt-to-debt restructurings that look like routine refinancings. A company that extends maturity and lowers the rate on a note may not realize it has just triggered a deemed exchange, potentially generating COD income when the issue price of the “new” instrument is less than the adjusted issue price of the old one. A modification that doesn’t cross the significance threshold is treated as a continuation of the existing debt with no immediate tax consequence.
