What are the 10 most overlooked tax deductions?

From student loan interest to military moving expenses, claiming overlooked tax deductions can help you keep more money in your pocket, so it is worth checking whether you can deduct legal fees. But to take advantage of all the deductions you're entitled to claim, you have to know they exist. Knowledge is the key!

So, to help you identify tax deductions you may not have known about, here's our list of the 10 most overlooked tax deductions. Claim them if you deserve them, and cut your tax bill to the bone.

1. State sales taxes

This write-off makes the most sense for those who live in a state with no income tax. We’re lookin’ at you, Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. However, you must itemize to deduct state sales taxes (which means you can't claim the Standard Deduction).

Here’s why this is a factor. If you claim the deduction for state and local taxes (commonly referred to as the SALT Deduction), you must choose between deducting state and local income taxes or state and local sales taxes. For most residents of income-taxing states, deducting your state and local income taxes is usually the better deal. But if you live in one of the states without an income tax, deducting your sales tax is the way to go if you're claiming the SALT Deduction (assuming your state has a sales tax).

How do you claim the state sales tax deduction?

For those of you in an income-tax-free state, there are two ways to claim the sales tax deduction on your tax return. One, you can use the IRS tables provided for your state to determine what you can deduct. In addition, if you purchased a motor vehicle, boat, airplane, home, or did major home renovations, you may be able to add the state sales tax you paid on these big-ticket items to the amount shown in the IRS tables. Or two, you can keep track of all of the sales tax you actually paid throughout the year and use that.

How do you know how much you can deduct in sales tax?

If you're not using the actual sales taxes paid during the year to figure your sales tax deduction, TurboTax will help you calculate the deductible amount so you don't have to deal with the IRS tables (the IRS also has an online Sales Tax Calculator).

Keep in mind, the total of your itemized deduction for all of your state and local taxes is limited to $40,000 for the 2025 tax year (increasing to $40,400 for 2026), with reductions based on your income possible (but no lower than $10,000). This limit is scheduled to drop to $10,000 per year in 2029 (which was the limit before 2025).

2. Alimony paid to a former spouse

If you're paying alimony to an ex-spouse, you might be able to deduct those payments. The catch is that alimony is only deductible if it's paid under a divorce or separation agreement from before 2019. If it's paid according to a post-2018 agreement, the deduction isn't allowed.

You also can't deduct alimony paid under a pre-2019 divorce or separation agreement that's modified after 2018 to expressly state that the alimony isn't deductible or includible in your former spouse's taxable income.

3. Out-of-pocket charitable contributions

It’s hard to overlook the big charitable gifts you make during the year by check or payroll deduction. But many people don't realize they can also write off out-of-pocket costs incurred while doing good deeds.

If you itemize, ingredients for casseroles you regularly prepare for a qualified nonprofit organization’s soup kitchen, for example, or the cost of stamps you buy for your school’s fundraiser can count as a deductible charitable contribution. If you drove your car for a qualifying charity, remember to deduct 14 cents per mile. Many people may not know how do church donations affect taxes, and need to learn more about IRS rules for church donations.

4. Student loan interest paid by you or someone else

You can typically deduct student loan interest from your taxes, even if it was paid by someone else on your behalf. Up to $2,500 of interest can be deducted. The IRS treats payments made by someone else as if you received the money and paid the loan yourself, making you eligible for the deduction even if you did pay the money yourself. 

5. Moving expenses

If you’re an active duty military member who is relocating for a permanent assignment, you can deduct moving expenses from your taxes, as long as you don’t receive reimbursement from the government for the move.

Starting with the 2026 tax year, employees and new appointees of the intelligence community can also claim the moving expense deduction if they move because of a change in assignment that requires relocation. 

What can you deduct from your moving expenses?

Qualified moving expenses that can be deducted include:

• travel and lodging for you and your family
• moving household goods
• shipping vehicles and pets

If your relocation is permanent and ordered by the military, you also don’t pay taxes on any qualified moving expense reimbursements.

TurboTax Tip:

Tax credits, such as the Child and Dependent Care Credit and the Earned Income Credit, are even better than a tax deduction because they reduce your tax bill dollar for dollar.

6. Educator expenses

For the 2025 tax year, teachers, instructors, counselors, principals, and aides who worked in an elementary or secondary school (kindergarten through 12th grade) for at least 900 hours during the school year can claim an "above-the-line" deduction of up to $300 ($350 for 2026) of out-of-pocket costs for:

• professional development courses related to the curriculum or students you teach
• books, supplies, equipment, and other materials used in the classroom

This deduction is available to educators working in public, private, and religious schools. However, it doesn't apply to expenses for home schooling.

If both you and your spouse qualify and file a joint return for 2025, you each can deduct up to $300 of qualified expenses (for a total of up to $600). This amount increases to $350 and $700, respectively, for 2026.

Plus, starting with the 2026 tax year, qualified educators can an itemized deduction for certain unreimbursed expenses, such as books, supplies, and equipment. This deduction is similar to the existing "above-the-line" deduction for educator expenses, except:

• there are no dollar limits
• coaches and interscholastic sports administrators can claim it
• it can be claimed for non-athletic supplies for health or physical education classes
• items purchased by the teacher or other educator don’t have to be used in the classroom if they’re used as part of an instructional activity

7. Gambling losses

There might be a silver lining if you have some bad luck at the casino, betting on horses, or even playing the lottery – you might be able to deduct some of your gambling losses on your federal income tax return. However, you can't deduct more than your gambling winnings for the year.

Beginning in 2026, this deduction limit is changed to the smaller of:

• 90% of your gambling losses for the tax year
• your gambling winnings for the tax year

In addition, you can only deduct gambling losses if you claim itemized deductions on your return. If you take the Standard Deduction, you can't write off your gambling losses.

8. State income tax you paid last spring

Did you owe taxes on your state income tax return last year? Then remember to include that amount with your state income tax itemized deduction on this year’s return, along with state income taxes withheld from your paychecks or paid via quarterly estimated payments.

9. Refinancing mortgage points

When you buy a house, you can usually deduct the points you paid to secure your mortgage in a single year if you itemize. When you refinance a mortgage, however, you have to deduct the points over the life of the new loan. That means you can deduct 1/30th of the points a year if it’s a 30-year mortgage—that’s $33 a year for each $1,000 of points you paid. Doesn't seem like much, but why throw it away?

Also, in the year you pay off the loan—because you sell the house or refinance again—you get to deduct all the points not yet deducted, unless you refinance with the same lender.

10. Jury pay paid to employer

You can deduct jury fees that you turn over to your employer, so you aren’t taxed on income that simply passes through your hands. Some employers continue to pay your full salary while you serve on a jury, but require that you submit your jury pay to the company. Normally, those fees are considered taxable income, but by deducting the amount given to your employer, you avoid being taxed on money you don’t actually keep.
