About the Canceled Debt Tax Calculator
When a lender forgives or settles a debt for less than you owe, the IRS generally treats the canceled amount as income — and lenders must file Form 1099-C for canceled debt of $600 or more. This canceled debt tax calculator estimates how much of that amount is actually taxable after the insolvency exclusion, and roughly how much tax it adds.
Under IRS Publication 4681 you were insolvent to the extent your total liabilities exceeded the fair market value of all your assets immediately before the cancellation. You can exclude canceled debt from income up to that insolvency amount. Assets include everything you own, even retirement accounts and pension interests that creditors cannot reach. Debt discharged in a Title 11 bankruptcy case is excluded entirely.
Use it after a debt settlement, credit card charge-off, repossession shortfall or similar cancellation to see whether to expect a tax bill. The tax estimate applies your marginal rates to the taxable amount, which is an approximation; claim the exclusion on Form 982 and see a tax professional for complex cases such as mortgage debt or business property. Rules reflect IRS Publication 4681 for 2025 returns and the April 2025 Form 1099-C instructions, which still apply to 2026 cancellations.
With the default inputs, the taxable canceled debt is $5,000.00. Change any value above to recalculate instantly.
How to use the canceled debt tax calculator
- 1Enter the canceled debt amount from Form 1099-C.
- 2Total all your debts as of the day before the cancellation, including the canceled one.
- 3Total the fair market value of everything you owned that day, including retirement accounts.
- 4Tick the bankruptcy box if the debt was discharged in a bankruptcy case.
- 5Pick your marginal federal rate and state rate to estimate the tax owed.
Formula and method
IRS Publication 4681 says you are insolvent to the extent your total liabilities exceed the fair market value of your total assets immediately before the debt is canceled. You may exclude canceled debt from income only up to that amount, so the excluded part is the smaller of the canceled debt and the insolvency amount; the rest is ordinary income. Debt canceled in a Title 11 bankruptcy case is excluded in full.
The tax estimate multiplies the taxable amount by your federal marginal rate and state rate. That is a reasonable approximation when the extra income stays within one bracket; a large cancellation can push part of it into a higher bracket, and other exclusions (such as certain student loan or farm debt rules) are not modeled.
- Liabilities
- All debts immediately before the cancellation, including the canceled debt
- Assets
- Fair market value of everything you own, including retirement accounts
- Canceled
- Amount of debt forgiven (Form 1099-C box 2)
Worked examples
$15,000 settled, insolvent by $10,000
Liabilities of $60,000 against $50,000 of assets mean you were insolvent by $10,000. That much of the $15,000 canceled debt is excluded, leaving $5,000 taxable. At 22% federal and 5% state, that adds about $1,350 of tax.
Deeply insolvent — the IRS example
With $15,000 of liabilities and $7,000 of assets you were insolvent by $8,000. Because that exceeds the $5,000 canceled, the whole amount is excluded — the same result as the example in IRS Publication 4681.
Solvent homeowner with a settled card
Home equity and retirement savings push assets $90,000 above liabilities, so there is no insolvency exclusion. The full $8,000 is taxable; at a 24% bracket in a no-income-tax state that is about $1,920.
Frequently asked questions
Is forgiven debt taxable?+
Generally yes. The IRS treats canceled debt as ordinary income unless an exclusion applies, such as insolvency, a Title 11 bankruptcy discharge, or specific rules for certain farm, business real property and student loan debt.
How do I prove I was insolvent?+
List every liability and the fair market value of every asset as of the moment before the cancellation — IRS Publication 4681 includes an insolvency worksheet for this. Keep statements and valuations with your records in case the IRS asks.
Do retirement accounts count as assets for insolvency?+
Yes. Publication 4681 says assets include exempt assets beyond the reach of creditors, specifically including pension plan interests and retirement accounts. That often reduces or eliminates the insolvency amount.
What if I did not receive a 1099-C?+
Canceled debt is still income even without the form. Lenders only have to file Form 1099-C when $600 or more is canceled, so smaller amounts or missing forms do not change whether the income must be reported.
Is forgiven mortgage debt on my main home still excluded?+
The qualified principal residence indebtedness exclusion covered debt discharged before January 1, 2026 (or under a written agreement made before then). For later cancellations you generally need another exclusion, such as insolvency or bankruptcy, to keep forgiven mortgage debt out of income.
Which form do I use to claim the insolvency exclusion?+
File Form 982, Reduction of Tax Attributes Due to Discharge of Indebtedness, with your tax return. Check the insolvency box and enter the excluded amount; the exclusion also reduces tax attributes like net operating losses and asset basis.
