You do not pay taxes on a loan. Money you borrow — whether a mortgage, auto loan, student loan, credit card balance, personal loan, or business line of credit — is not treated as income, because the cash coming in is matched by an obligation to pay it back. No lender issues a 1099 for loan proceeds, and no line on your tax return asks you to report them. The tax picture only changes if the debt is later forgiven, if you borrowed under unusual terms, or if you tapped certain accounts to get the money.
Why Borrowed Money Is Not Taxed
The federal definition of gross income is broad, covering income “from whatever source derived.”1Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined Even so, a loan doesn’t fit. When a lender deposits $50,000 in your account, your assets rise by $50,000 and your liabilities rise by the same amount. Your net worth hasn’t changed, so there’s nothing for the IRS to tax. This is why lenders don’t report loan disbursements to the IRS and why you never see borrowed funds on your return. As long as the debt stays outstanding or gets paid off on schedule, the whole transaction is invisible for income tax purposes.
When Canceled or Forgiven Debt Becomes Taxable
The tax-free treatment ends the moment you stop owing the money without paying it back. Federal law lists “income from discharge of indebtedness” as a category of gross income.1Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined The reasoning is direct: if you borrowed $15,000 on a credit card and the issuer settles for $5,000, you kept $10,000 worth of value you’ll never repay. That $10,000 is taxed like ordinary wages.
When a lender cancels $600 or more of your debt, it files Form 1099-C with the IRS and sends you a copy showing the amount discharged and the date.2Internal Revenue Service. About Form 1099-C, Cancellation of Debt You report that amount as income at your ordinary rate. Cancellation can happen through a negotiated settlement, a lender writing off an old balance, a foreclosure where the sale price falls short of the mortgage, or a loan forgiveness program. The trigger is the same in every case: the obligation to repay disappears.
Do not ignore a 1099-C. The IRS already has its copy, and an unreported amount will almost always produce a notice. An accuracy-related penalty of 20% of the underpayment can apply on top of the tax itself.3Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments
Exclusions That Can Wipe Out the Tax on Canceled Debt
Not every discharge produces a tax bill. Federal law carves out several situations where some or all of the forgiven amount stays out of income.4Office of the Law Revision Counsel. 26 USC 108 – Income From Discharge of Indebtedness To claim any of them, you file Form 982 with your return.5Internal Revenue Service. About Form 982, Reduction of Tax Attributes Due to Discharge of Indebtedness
Debt discharged in a Title 11 bankruptcy case is fully excluded from income. This is the broadest exclusion and takes priority over the others.
Insolvency is the exclusion most consumers rely on. If your total liabilities exceed the fair market value of your total assets immediately before the discharge, you’re insolvent, and you can exclude canceled debt up to the amount of that insolvency. If you owe $120,000 and own assets worth $100,000, you’re insolvent by $20,000 and can exclude up to $20,000 of the canceled amount.4Office of the Law Revision Counsel. 26 USC 108 – Income From Discharge of Indebtedness
One exclusion many homeowners depended on is gone. The qualified principal residence indebtedness exclusion, which shielded forgiven mortgage debt on a primary home, expired for discharges occurring after December 31, 2025.6Internal Revenue Service. Publication 4681, Canceled Debts, Foreclosures, Repossessions, and Abandonments Starting in 2026, forgiven mortgage debt from a short sale or loan modification is taxable unless bankruptcy or insolvency applies.
Each exclusion carries a trade-off: the excluded amount generally reduces other tax attributes you’d otherwise carry forward, such as net operating losses, capital loss carryovers, or the cost basis in your property.7Internal Revenue Service. Instructions for Form 982 The tax isn’t erased so much as deferred.
Loan Interest and Tax Deductions
The principal is tax-neutral, but the interest you pay follows its own rules. For individuals, the default rule is that personal interest is not deductible.8Office of the Law Revision Counsel. 26 USC 163 – Interest Credit card interest, auto loan interest, and interest on personal lines of credit all come out of after-tax dollars with no relief.
Two exceptions matter for most people. If you itemize, you can deduct interest on up to $750,000 of mortgage debt used to buy, build, or substantially improve your primary or secondary home, or $375,000 if married filing separately.8Office of the Law Revision Counsel. 26 USC 163 – Interest Loans taken out before December 15, 2017 still fall under the older $1,000,000 cap. Home equity debt used for anything other than improving the home doesn’t qualify.
You can also deduct up to $2,500 per year in interest on qualified education loans without itemizing.9Office of the Law Revision Counsel. 26 USC 221 – Interest on Education Loans For 2026, the deduction phases out between $85,000 and $100,000 of modified adjusted gross income for single filers, and between $175,000 and $205,000 for joint filers.
Business interest is generally deductible as a business expense, but larger businesses face a cap: the deduction can’t exceed 30% of adjusted taxable income plus any business interest income received. Small businesses averaging $30 million or less in gross receipts over the prior three years are generally exempt.10Internal Revenue Service.

Family Loans and the Applicable Federal Rate
A common place where the “loans aren’t taxed” assumption breaks down is family lending. If you lend money to a relative at zero interest or below the Applicable Federal Rate (AFR) the IRS publishes each month, the loan is a below-market loan.11Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates The gap between what you charged and what the AFR called for is “forgone interest,” and the IRS treats it as if the lender gifted that amount to the borrower, who then paid it back as interest. The lender reports that phantom interest as income.
As of early 2026, the short-term AFR sits around 3.6%, the mid-term rate near 3.9%, and the long-term rate near 4.7%, with the applicable rate depending on the loan’s duration.12Internal Revenue Service. Revenue Ruling 2026-6, Applicable Federal Rates for March 2026 If the forgone interest exceeds the $19,000 annual gift tax exclusion per recipient, the lender also needs to file Form 709.13Internal Revenue Service. Frequently Asked Questions on Gift Taxes
Smaller loans get some relief. If the total outstanding balance between two individuals stays at or below $10,000, the below-market rules don’t apply, provided the loan isn’t used to buy income-producing assets.11Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates Between $10,000 and $100,000, imputed interest is capped at the borrower’s net investment income for the year, which often means no tax if the borrower holds few investments. Above $100,000, the full AFR applies with no cap.
Put the terms in writing. A promissory note that specifies the principal, an interest rate at or above the AFR, a repayment schedule, and a maturity date keeps the transaction from being reclassified as a gift.
Life Insurance Policy Loans
Borrowing against the cash value of a permanent life insurance policy is not a taxable event. The loan uses the policy’s cash value as collateral, there’s no credit check, and there’s no mandatory repayment schedule.
The tax hits when the policy ends. If you surrender the policy or it lapses — often because unpaid interest consumes the remaining cash value — the IRS treats the outstanding loan balance plus anything you received as a distribution. Amounts exceeding your cost basis (generally the premiums you’ve paid, less any tax-free distributions or dividends) are taxable, and you’ll get a Form 1099-R showing the amount.14Internal Revenue Service. For Senior Taxpayers 1 A policy with $200,000 in cash value against $80,000 in premiums could generate $120,000 of taxable income if it lapses with a large loan against it. Keep the loan well below the policy’s cash surrender value.
Loans From a 401(k) or Other Retirement Plan
Many 401(k), 403(b), and some 457 plans let participants borrow from their own vested balance. The maximum is the lesser of $50,000 or 50% of your vested balance, though individual plans may set lower limits.15Internal Revenue Service. Retirement Topics – Plan Loans Follow the rules and the money comes out tax-free. You repay it with interest into your own account.
The rules are strict. Payments must be made at least quarterly, and the loan has to be fully repaid within five years unless it was used to buy your primary residence.15Internal Revenue Service. Retirement Topics – Plan Loans Fall behind and the outstanding balance becomes a “deemed distribution,” reported on Form 1099-R and added to your taxable income.16Internal Revenue Service. Instructions for Forms 1099-R and 5498 If you’re under 59½, an additional 10% early distribution tax applies.17Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
Leaving your job with an outstanding plan loan creates a related problem. The unpaid balance becomes a “plan loan offset,” which is essentially a forced distribution. You can avoid the tax by rolling that amount into an IRA, but the deadline depends on why the offset happened. If it came from leaving the job or the plan terminating, you have until your tax filing due date, including extensions, for that year. If the offset came from simply missing payments, you have only 60 days.18Internal Revenue Service. Plan Loan Offsets Miss the window and the full amount is taxable, and potentially hit with the early distribution penalty on top.
