The Student Loan Interest Deduction in 2026: What Your Clients Can Still Claim

Yes, the student loan interest deduction is still here in 2026, and most clients who are repaying federal or private student loans can take it. It is worth up to $2,500 a year, it comes off income before adjusted gross income, and your client does not have to itemize to claim it. What changed for 2026 is small but real: the income limit for married couples moved up, so a few clients who phased out last year are back in range.

Here is what to keep at hand, and the one filing decision that quietly cancels the whole benefit.

The short version

The deduction lets a borrower subtract the interest they paid on a qualified education loan, up to $2,500, as an adjustment to income. Because it is an above-the-line adjustment, it lowers adjusted gross income directly. That matters twice. It cuts the tax bill, and a lower AGI can also lower an income-driven student loan payment down the road. The deduction shrinks as income rises and disappears entirely above a ceiling.

The 2026 numbers

For tax year 2026, per the IRS inflation adjustments in Revenue Procedure 2025-32, the deduction phases out over these modified adjusted gross income (MAGI) ranges:

Filing status	Phaseout begins (MAGI over)	Fully gone at (MAGI of)
Single, head of household, qualifying surviving spouse	$85,000	$100,000
Married filing jointly	$175,000	$205,000
Married filing separately	Not eligible at any income

Between the two numbers the deduction slides down on a scale. Below the start, the full $2,500 is available if the client actually paid that much in interest. The $2,500 cap is not indexed to inflation, so it stays flat while the income limits drift up each year. For 2026 the joint-filer range rose by $5,000 at both ends versus 2025, while the single-filer range held steady.

The filing-status trap worth flagging

Married filing separately cannot claim the deduction at all. Not a reduced amount. Zero.

That collides with a common student loan move. Borrowers on income-driven plans sometimes file separately so their payment is calculated on their own income instead of household income, which can lower the monthly bill. The same election erases the student loan interest deduction, and it usually costs the couple other tax benefits too.

So the real question is never “does filing separately lower the payment.” It is “does the payment savings beat the tax cost of filing separately, this year and every year until forgiveness.” That is a two-sided calculation, and it is exactly where a fast gut answer gets clients in trouble.

Who else cannot take it

A client claimed as a dependent on someone else’s return cannot take the deduction. This trips up families where a parent still claims a working adult child who is the one actually paying the loan.
The debt has to be a qualified education loan the client is legally obligated to repay. A parent paying a loan that is in the child’s name gets no deduction, and the child gets none either if the parent claims them as a dependent.

A newer angle: employer help is now permanent

One change from the 2025 tax law is worth putting in front of clients. Employers can pay up to $5,250 a year toward an employee’s student loans tax-free, and that benefit was set to expire for loan payments after 2025. The One Big Beautiful Bill Act made it permanent, and the $5,250 cap will be adjusted for inflation for years after 2026.

For advisors, that is a simple line to add to a client review: does your employer offer student loan repayment assistance, and are you using it. Tax-free employer dollars beat a deduction on interest the client paid out of pocket. Coordinate the two so the same dollar of interest is not counted for both.

Where this lands in a plan

Filing status is the thread that ties all of this together. It changes the interest deduction, it changes the income-driven payment, and it moves a stack of other credits. Advisors who model those effects together, instead of one at a time, hand clients an answer they can act on.

Finology Software puts the repayment math and the filing-status effect in one place, so you can show a client the monthly payment and the tax tradeoff of filing separately side by side, with numbers that hold up. That is the difference between “it depends” and a recommendation you can defend.
