Questions about this calculator

What is the student loan tax bomb?

When a balance is forgiven at the end of a 20–30 year income-driven plan, the forgiven amount is generally taxed as ordinary income that year — a large one-time bill. PSLF forgiveness is the exception: it's tax-free, so it has no tax bomb.

How is the tax bomb estimated?

We add the forgiven balance on top of your other taxable income and compute the additional federal tax using 2025 brackets, then add your state rate. It's an estimate — your actual bracket, deductions, and state rules will differ, so confirm with a CPA.

Does PSLF have a tax bomb?

No. PSLF forgiveness is excluded from federal taxable income. The tax bomb only applies to long-term income-driven forgiveness (RAP, IBR, etc.), which is why pursuing PSLF when you qualify is so valuable.
