Featured Snippet: What are the new student loan rules for 2026?
2026 Student Loan Changes
- Two Repayment Plans:Standard (10-25 years) and Repayment Assistance Plan (RAP), an income-driven plan
- Grad PLUS Elimination:Grad PLUS loans are eliminated for new borrowers as of July 1, 2026
- Borrowing Caps:Graduate students: $20,500/year unsubsidized. Professional degrees: $50,000/year
- Taxable Forgiveness:Loan forgiveness after January 1, 2026, is considered taxable income at the federal level
- Interest Subsidy:Under RAP, unpaid monthly interest is waived if minimum payment is met, preventing balance growth
These changes apply to new loans taken out after July 1, 2026. Existing borrowers may be grandfathered into previous plans.
Understanding the Repayment Assistance Plan (RAP)
RAP Payment Calculation
- Formula:Monthly Payment = (AGI ร Payment Rate / 12) - (Dependents ร $50)
- Payment Rate:Between 1% and 10% of Adjusted Gross Income (AGI)
- Dependent Deduction:$50 per dependent child, reducing your payment
- Minimum Payment:$10/month, even if the calculation results in a lower amount
- Example:AGI of $50,000, 5% rate, 2 dependents: ($50,000 ร 0.05 / 12) - (2 ร $50) = $108.33/month
The $10 minimum ensures all borrowers make some progress, while the dependent deduction helps families with children.
Interest Subsidy and Balance Protection
- Interest Waiver:If your RAP payment is less than your monthly interest, the unpaid interest is waived
- Balance Protection:This prevents your loan balance from growing, unlike previous income-driven plans
- Example:If your payment is $10 but interest is $200, the government pays $190/month in interest subsidy
- Benefit:Your balance stays stable or decreases, even with low payments
This interest subsidy is a significant improvement over previous income-driven plans where unpaid interest was capitalized, causing balances to balloon.
Standard Repayment Plan 2026
Standard Plan Terms and Calculation
- Term Length:10 to 25 years, depending on loan balance
- Extended Term:Loans over $25,000 can extend up to 25 years
- Payment Formula:Payment = P ร [r(1 + r)^n] / [(1 + r)^n - 1]where P = principal, r = monthly rate, n = number of payments
- Advantage:Fixed payments, predictable payoff date, no forgiveness tax
- Disadvantage:Higher monthly payments than income-driven plans
The Standard plan is best for borrowers who can afford higher payments and want to pay off their loans faster without relying on forgiveness.
2026 Tax Treatment of Loan Forgiveness
Taxable Forgiveness Returns
- Taxable Date:Forgiveness granted after January 1, 2026, is taxable
- Tax Calculation:Tax Liability = Forgiven Amount ร Marginal Tax Rate
- Example:$50,000 forgiven at 22% tax rate = $11,000 in taxes
- Planning:Set aside funds for the tax bill, or consider paying off loans before forgiveness to avoid taxes
- Impact:The "tax bomb" significantly reduces the benefit of forgiveness for many borrowers
This is a major change from the temporary tax-free forgiveness period. Plan ahead for the tax liability on any forgiven amount.
2026 Borrowing Limits and Grad PLUS Elimination
New Borrowing Caps
- Graduate Students:$20,500/year in unsubsidized Direct Loans (down from unlimited Grad PLUS)
- Professional Degrees:$50,000/year for medical, law, and other professional programs
- Undergraduate Rates:2025-2026 fixed rate: 6.39% for Direct Subsidized and Unsubsidized Loans
- Impact:Students may need to rely more on private loans or reduce borrowing
These caps apply only to new loans taken out after July 1, 2026. Existing borrowers are not affected.
