Who pays for student loan forgiveness comes down to two parties: the federal government, which owns roughly $1.7 trillion in loans across 42.8 million borrowers and absorbs the unpaid balance when a loan is discharged, and, starting in 2026, borrowers themselves, who now owe federal income tax on amounts forgiven through income-driven repayment. Taxpayers carry the larger share because the government funds itself through tax revenue and borrowing, and every forgiven dollar is a dollar it expected to collect and won’t.
The Government Writes Off Its Own Asset
Most federal student loans are funded directly by the U.S. government through the William D. Ford Federal Direct Loan Program, established under the Higher Education Act of 1965. The Department of Education originates the loans, sets the terms, and collects the payments. Private servicers handle billing, but the government owns the debt. So when forgiveness happens, no private creditor takes a loss. The government is canceling money owed to itself.
On the federal books, student loans sit as assets because they represent a legal right to future payments. When the Department of Education approves a discharge, it removes that asset. The U.S. Treasury records the loss. No check goes to a bank; the government simply accepts that money it lent will not come back. Large forgiveness actions generate headlines about hundreds of billions in costs because those figures represent the present value of cash the government will never collect.
The legal authority behind this sits in 20 U.S.C. § 1082(a)(6), which lets the Secretary of Education enforce, pay, compromise, waive, or release any claim the government holds on a student loan. That language is what allows forgiveness programs to operate without Congress voting on each discharge.
Why Taxpayers End Up Carrying It
The federal government funds its operations mostly through individual income taxes, payroll taxes, and borrowing. When a loan is forgiven, expected revenue drops, but other spending obligations do not. The gap fills the same way any budget shortfall does: tax revenue from the general public, or additional federal borrowing that adds to the national debt.
Nobody receives an itemized bill for student loan forgiveness. The cost is diffuse, spread across the whole federal budget. But the arithmetic is straightforward. Every dollar a forgiven borrower no longer sends to the Department of Education is a dollar the government has to collect from someone else or borrow. With a $1.7 trillion federal loan portfolio, even modest forgiveness percentages translate into large sums.
What Borrowers Now Pay Starting in 2026
Under the tax code, canceled debt generally counts as income. The IRS treats “income from discharge of indebtedness” as part of gross income, so a forgiven student loan balance can raise your taxable income for the year the debt is wiped out.
The American Rescue Plan Act of 2021 temporarily excluded most student loan forgiveness from federal income tax, but that provision covered only loans forgiven between January 1, 2022, and December 31, 2025. It has expired. If your federal student loans are forgiven under an income-driven repayment plan in 2026 or later, the forgiven amount is treated as taxable income at your ordinary income tax rate. You will receive a Form 1099-C from your loan servicer the following January or February, and you must report the canceled amount on your tax return for the year it was forgiven.
The practical impact can be severe. A borrower who has $80,000 forgiven after 20 years on an income-driven plan could see their taxable income spike dramatically for that single year, potentially pushing them into a higher tax bracket. The IRS Taxpayer Advocate Service advises borrowers expecting forgiveness to plan ahead by increasing withholdings, making estimated quarterly payments, or building savings for the anticipated tax bill.
Which Forgiveness Programs Stay Tax-Free
Not every discharge triggers a tax bill. Under 26 U.S.C. § 108(f), loan discharges tied to working in certain professions for qualifying employers stay excluded from gross income. In practice, that covers forgiveness offered as a reward for public service rather than as a fallback after decades of low payments.
- Public Service Loan Forgiveness remains tax-free because the discharge is conditioned on full-time work for a qualifying government or nonprofit employer, and it wipes remaining balances after 120 qualifying monthly payments.
- Teacher Loan Forgiveness stays tax-free for eligible teachers who serve five consecutive years in low-income schools.
- Discharges for death or total and permanent disability are tax-free regardless of employment history.
Income-driven repayment forgiveness does not qualify for this exclusion because it is not tied to the borrower’s profession or employer. That distinction is what creates the so-called “IDR tax bomb,” where borrowers who have made affordable payments for two decades receive a large, unexpected tax liability in the year their remaining balance is canceled.
The Insolvency Exception
If your total liabilities exceed the fair market value of your total assets at the time your loan is forgiven, you may qualify for the insolvency exclusion. You can exclude forgiven debt from taxable income up to the amount by which you are insolvent. If you owe $150,000 across all debts but your assets are worth $100,000, you are insolvent by $50,000 and can exclude up to that amount from income.
To claim the exclusion, you file IRS Form 982 (Reduction of Tax Attributes Due to Discharge of Indebtedness) with your tax return. The IRS recommends keeping detailed financial records documenting your assets and liabilities at the time of discharge. Many long-term IDR borrowers whose balances ballooned through capitalized interest may qualify, since their liabilities often dwarf their assets by the time forgiveness arrives.
State Taxes Are a Separate Question
State tax treatment of forgiven student loans varies. Some states automatically follow the federal tax code, so debt that is taxable federally is also taxable at the state level. Others have passed their own exclusions. A few states have no income tax at all. Because state legislatures can change conformity rules at any time, the only reliable way to know your exposure is to check your state’s current tax code or consult a tax professional in the year your loans are forgiven.
A borrower with $40,000 in forgiven debt living in a state with a 5% income tax rate and no exclusion would owe $2,000 in state taxes on top of any federal liability. Combined, the total out-of-pocket cost of “free” forgiveness can run into the thousands. Borrowers approaching IDR forgiveness should account for both federal and state exposure well before the forgiveness date.
The Split by Forgiveness Pathway
Who pays how much depends on how the loan gets forgiven. For PSLF recipients, the federal government (and by extension, taxpayers) picks up the entire tab. The borrower pays nothing in taxes, and whatever balance remains after ten years of qualifying payments is written off. For income-driven repayment forgiveness in 2026 and beyond, the cost is split: taxpayers lose the forgiven principal and decades of expected interest, while the borrower faces an immediate tax bill on the canceled amount. Borrowers who qualify for the insolvency exception shift that tax cost back onto the government as uncollected revenue.
The scale tips further toward taxpayers when you consider that many borrowers on income-driven plans pay less than the accruing interest for years, meaning the balance that eventually gets forgiven can be larger than the original loan. The government lent the money, watched it grow through capitalized interest, and then wrote off the entire inflated balance. The borrower, meanwhile, may have paid thousands over two decades without reducing the principal at all. That gap between what was collected and what was forgiven is the real cost of these programs, and it lands on the federal balance sheet.
