Income-Driven Repayment Plans Compared: What Actually Works in 2026

Diagram showing how IDR payment is calculated as a percentage of discretionary income

More than 7.6 million people spent 2025 watching their student loan repayment plan collapse in slow motion. The SAVE plan — which the Biden administration launched in 2023 as the most affordable income-driven option ever — was blocked by the Eighth Circuit Court of Appeals, kept millions in interest-free limbo for over a year, then officially eliminated by court order on March 10, 2026. The One Big Beautiful Bill Act, signed on July 4, 2025, had already sealed the deal by statute months earlier.

If you were one of those borrowers, you're now choosing between options you probably haven't seriously evaluated since graduation.

Here's what exists in 2026, what's going away, what's coming, and how to pick one.

How IDR Payment Math Actually Works

Every income-driven repayment plan runs on the same engine: your monthly payment is a percentage of your discretionary income, not your total income. That distinction matters a lot.

Discretionary income = your Adjusted Gross Income (AGI) minus a protected floor tied to the federal poverty guideline for your family size. For a single person in 2026, that guideline is $15,650. Different plans protect different multiples:

IBR and PAYE protect 150% of the guideline — so the first $23,475 of income is completely shielded
ICR only protects 100%, leaving just $15,650 shielded
SAVE (now gone) protected 225%, shielding $35,213

At $50,000 AGI and single status, IBR treats $26,525 as your discretionary income. Ten percent of that is $2,652/year, or $221/month, regardless of whether you owe $30,000 or $250,000.

A doctor in residency earning $60,000 on $200,000 in medical school debt pays about $304/month under New IBR. Standard repayment on that balance runs closer to $2,100/month.

This is where IDR shows its teeth.

IBR: The Plan That Outlasted the Rest

IBR is now the anchor plan for most borrowers. SAVE is gone. PAYE and ICR sunset in 2028. RAP doesn't launch until July 2026. IBR is permanent, open to new enrollees, and the partial financial hardship requirement was removed in 2025 — you no longer need to prove your IBR payment is lower than your standard 10-year amount to qualify.

Two versions exist based on when you first borrowed:

New IBR (first loan on/after July 1, 2014):

10% of discretionary income
Forgiveness after 20 years
Payment capped at the standard 10-year amount

Old IBR (first loan before July 1, 2014):

15% of discretionary income
Forgiveness after 25 years
Same payment cap

The difference is significant. At $65,000 AGI, New IBR runs about $346/month. Old IBR on the same income: $519/month. Over 20 years, those extra $173/month add up to more than $41,500 before compounding. Not trivial.

If you have both pre-2014 and post-2014 loans (common with graduate school), each loan follows its own IBR version. You don't pick one rule for everything — the calculations run separately by disbursement date.

One lever most borrowers underuse: pre-tax retirement contributions reduce your AGI, which is exactly what IDR uses for the payment calculation. A borrower who maxes a 401(k) at $23,500 in 2026 doesn't just save for retirement — they cut their IDR payment for that year too. This isn't a loophole. It's the intended design.

PAYE and ICR: Sunset Plans Worth Understanding

PAYE (Pay As You Earn) works nearly identically to New IBR: 10% of discretionary income, 20-year forgiveness, same payment cap. The catch is eligibility. PAYE requires your first Direct loan disbursement after October 1, 2011, with no outstanding federal loans as of October 1, 2007. It also closed to new enrollees in 2023.

If you're already on PAYE, there's no urgent reason to switch before 2028. The terms track closely enough to New IBR that staying put is fine. Just plan for the transition when PAYE sunsets on July 1, 2028.

ICR (Income-Contingent Repayment) is the plan nobody wants to be on — except for one specific group. Its formula is the least favorable of any IDR option: 20% of discretionary income calculated against only 100% of the poverty line. At $40,000 AGI single, ICR payments run about $406/month. New IBR on the same income: $138/month. ICR's forgiveness timeline is 25 years.

The one group that genuinely needs ICR: Parent PLUS loan borrowers. Parent PLUS loans can only enter IDR through a specific path — consolidate into a Direct Consolidation Loan, then enroll in ICR. And there's a hard deadline that doesn't get enough attention: you must consolidate and enroll before July 1, 2026. After that date, Parent PLUS borrowers lose IDR access entirely under the new law.

If you have Parent PLUS loans, that deadline is the most urgent action item in this article.

RAP: The Replacement Plan Arriving July 2026

The Repayment Assistance Plan launches July 1, 2026 and becomes the only IDR option for new borrowers with first disbursements on or after that date. Existing borrowers can also switch to it voluntarily.

RAP departs from the legacy discretionary income model. Instead, payments are calculated as a tiered percentage of your total AGI:

Rates range from 1% to 10% based on income bracket
Minimum payment: $10/month
Forgiveness: 30 years

That 30-year forgiveness timeline is RAP's most significant drawback (at least for anyone already working toward 20-year IBR forgiveness). Switching from IBR to RAP to capture lower short-term payments could mean forfeiting years of progress toward an earlier forgiveness date.

RAP does offer one structural benefit: it waives any unpaid monthly interest. Your balance won't grow even if your payment doesn't cover full accrual. For borrowers anxious about balances spiraling upward despite making payments, that's meaningful.

For most existing borrowers already in repayment, RAP is probably not the right move. The 30-year forgiveness clock is a steep price for modest payment savings if you're already five or ten years into your IBR timeline.

The Forgiveness Tax You Weren't Planning For

This is the part most plan comparisons skip entirely. Non-PSLF loan forgiveness is now taxable income.

The American Rescue Plan Act temporarily made student loan forgiveness tax-free through December 31, 2025. That window closed without renewal. Starting in 2026, any amount forgiven under IBR, ICR, PAYE, or RAP after 20 to 30 years gets added to your gross income for that tax year — the same as if you'd earned it from a job.

Here's what that looks like in practice: if you're on New IBR for 20 years and your remaining balance at forgiveness is $90,000, the IRS treats that $90,000 as ordinary income. Combined with whatever you're earning at that point, you could easily owe $25,000 or more in federal taxes in a single year.

Tony Bartels, DVM, MBA at the Veterinary Information Network — who personally manages over $400,000 in veterinary school debt through federal IDR plans — has been writing about this for years. His recommendation: treat the future forgiveness tax as a known liability and start saving toward it now, even if forgiveness is a decade away. The earlier you start, the less it stings.

The one clean exception is PSLF. Forgiveness after 120 qualifying payments in public service employment remains permanently tax-free by law. That asymmetry — taxable IDR forgiveness versus tax-free PSLF — shifts the math significantly for anyone who qualifies.

How to Choose the Right Plan

Work through this in order.

Start with eligibility:

First loan disbursed on/after July 1, 2026? RAP is your only IDR option.
Parent PLUS loans? Consolidate and enroll in ICR before July 1, 2026.
Otherwise: New IBR is available, permanent, and likely your best choice.

Then factor in your goals:

Situation	Best Plan	Why
Pursuing PSLF	New IBR	Lowest payments toward tax-free forgiveness
High debt, income below $65K	New IBR	10% cap, 20-year forgiveness
Residency or training (income growing)	New IBR, reassess annually	Locks low payment during low-income years
Parent PLUS borrower	ICR (consolidate before July 2026)	Only available IDR option
Currently on PAYE	Stay until 2028	Terms nearly match New IBR
First loan before July 2014	Old IBR	Limited alternatives available
New borrower (loans from July 2026+)	RAP	No choice — only plan available

My take: for anyone with loans from 2014 or later who isn't on a PSLF track, New IBR is the strongest active plan. The forgiveness timeline is shorter than RAP, the payment percentage beats Old IBR and ICR, and it's permanent. If your employer qualifies for PSLF, that path is even better — the tax-free forgiveness after 120 payments removes the biggest long-term financial risk in the IDR system.

The Annual Recertification Trap

Every IDR plan requires annual income recertification. Miss the deadline and your payment reverts to the standard 10-year amount (which can be four to six times your current IDR payment) until you recertify again.

The good news: recertification is fast. Using the IRS Data Retrieval Tool at StudentAid.gov takes about 15 minutes if your taxes are filed. The problem is forgetting it exists.

Two rules worth following. Set a calendar reminder 60 days before your recertification deadline — servicer emails about this reliably end up in spam. And if your income drops at any point during the year, request early recertification immediately. You don't have to wait for the annual window. Lower income should mean a lower payment as fast as possible.

Bottom Line

The IDR landscape changed more in 2025 and 2026 than in the previous decade. Here's what matters now:

New IBR is the default choice for most existing borrowers with loans from July 2014 or later. It's permanent, accessible, and the terms are strong.
Parent PLUS borrowers face a July 1, 2026 hard deadline to consolidate and enroll in ICR — after that date, IDR access disappears for this loan type entirely.
Plan for the forgiveness tax event if you're not pursuing PSLF. Start saving toward it now rather than treating forgiven debt as free money.
RAP arrives July 2026 but its 30-year forgiveness timeline means most current borrowers should stay on IBR unless they have a specific reason to switch.
Recertify annually. Missing it is an expensive, entirely avoidable mistake.

Frequently Asked Questions

Can I still enroll in the SAVE plan?

No. The SAVE plan was officially eliminated by court order on March 10, 2026, and the One Big Beautiful Bill Act (signed July 4, 2025) eliminated it by statute. Borrowers previously in SAVE forbearance are being moved to other repayment plans. A December 2025 settlement between the Trump administration and the State of Missouri blocked all new enrollments and pending applications.

What happened to the interest that accumulated during SAVE forbearance?

Interest began accruing again for SAVE borrowers on August 1, 2025, after the Department of Education notified over 7.6 million borrowers that interest-free forbearance was ending. This accrual was not retroactive to the start of forbearance in July 2024, so borrowers don't owe interest for the earlier window. But any unpaid interest since August 2025 has been capitalizing onto principal balances.

Does IBR still require proof of financial hardship to enroll?

Not anymore. The partial financial hardship requirement was removed in 2025 under the One Big Beautiful Bill Act. Any borrower with eligible Direct loans can now enroll in IBR regardless of whether their IDR payment would be lower than their standard payment amount. This meaningfully expands access, particularly for higher earners who previously would have been locked out.

Is IDR a good strategy if I'm pursuing Public Service Loan Forgiveness?

Yes — and the combination specifically rewards using the lowest-payment IDR plan available. Under PSLF, you're targeting forgiveness after 120 qualifying payments (10 years), so minimizing what you pay during those years reduces your total out-of-pocket cost while still reaching tax-free forgiveness. New IBR typically produces the lowest qualifying monthly payment for eligible borrowers. The PSLF tracker at StudentAid.gov lets you monitor your qualifying payment count in real time.

Is the amount forgiven under IBR really counted as taxable income?

Yes, with one exception. Forgiveness under IBR, ICR, PAYE, and RAP is treated as ordinary taxable income starting in 2026, after the American Rescue Plan Act's temporary exemption expired on December 31, 2025. PSLF forgiveness remains permanently tax-free. If you're on a non-PSLF IDR path with a substantial balance, build the future tax event into your long-term plan — it's a real liability, not a hypothetical.

What's the fastest path to loan forgiveness under IDR right now?

With SAVE eliminated, the shortest forgiveness timeline available is 20 years under New IBR or PAYE. PSLF cuts that to 10 years for qualifying borrowers and remains tax-free. For anyone chasing the fastest possible forgiveness on a non-PSLF path, New IBR at the lowest possible payment is the most practical route available today — particularly for borrowers whose debt significantly exceeds their annual income.
