The Most Overlooked Tax Deductions (2024)

Note that the TCJAdid away with the personal exemption, so you should factor that into your calculations.

The law also eliminated or changed the rules for a number of tax deductions that you were able to take in 2017. On the other hand, the TCJA doesn't limit overall itemized deductions according to your adjusted gross income (AGI), which is at least one positive change for itemizers.

If the total amount of your itemized deductions fallsbelow the amounts listed above, you’re better off taking the standard deduction. If not, read on to learn about the most overlooked itemized deductions and how they can help you save even more.

Tax Deductions for Homeowners

Owning a home can give you hefty tax write-offs each year. Here's a summary:

• Mortgage Interest: If you bought your home before Dec. 16, 2017, you can deduct mortgage interest payments on up to $1 million in loans used to buy, build, or improve your first or second home. If you purchased the home after Dec. 15, 2017, you can deduct mortgage interest on the first $750,000 of the loan. The $1 million limit is scheduled to return in 2025.
• Points: Lenders may charge points in exchange for providing a better interest rate. One point is equal to 1% of the total amount you mortgage. You can deduct points associated with a home purchase mortgage. In general, you can't deduct the full amount of points in the year you pay them. Instead, you typically deduct them over the life of the loan.
• Property Taxes: One of the most significant changes the TCJA made was to limit deductions for property taxes and other state and local taxes (SALT). For tax years 2018 through 2025, you can take a combined total deduction of $10,000 ($5,000 for married couples filing separately) for state and local income, sales, and property taxes.
• Home Office Deduction: If you use part of your home exclusively for business purposes—and your home is the principal place of your business—you may be able to deduct a percentage of home costs related to your work.
• Selling Costs: If you sell your home, you can lower your taxable capital gain by the amount of your selling costs—including real estate agent commissions, title insurance, legal fees, advertising costs, administrative costs, escrow fees, and inspection fees. Also, keep in mind that if you sell your home for a profit, you can exclude up to $250,000 of capital gains from your income, or up to $500,000 if you're married filing jointly.

Vehicle Sales Tax Deduction

You pay a sales tax on your car when you buy it. Some states continue to tax you each year simply for the privilege of using a car on public highways. Most states also send out a notice to demand their tax payment to register your car each year. You may be able to add that cost to your deductions for personal property taxes in April.

If your state calculates a percentage of the vehicle registration based on the value of your car, you can deduct that percentage as part of your personal property taxes. The percentage of the vehicle registration based on the weight of your car is not tax-deductible.

For example, in New Hampshire, a portion of car registration is deductible (the municipal portion which is calculated based on value) and a portion is not deductible (the state portion which is based on weight).

The same goes for an RV or boat. Check the registration paperwork to see if you are paying property taxes on those, too, and keep in mind the $10,000 cap on total SALT taxes.

Tax Deductions for Charitable Donations

You donated your skinny jeans and wagon-wheel coffee table to Goodwill, which, in turn, reduces your taxes by increasing your charitable deductions.The IRS requires that you provide “a qualified appraisal of the item or group of items” if you claim a deduction of more than $5,000 per item (or a group of similar items).

For items such as electronics, appliances, and furniture, you may need to pay a professional to assess the value of your donation.

For tax years 2023 and 2024, you're no longer able to deduct up to $300 ($600 if you're married and filing jointly) in cash donations made to qualifying charities, even if you take the standard deduction. This is called an above-the-line deduction. This was a 2021-only benefit that no longer applies.

If you itemize, you can usually write off up to 20% to 60% of your adjusted gross income (AGI) for charitable contributions. The amount varies depending on the type of contribution and the type of charity.

Tax Deductions for Volunteers

If you volunteer and use your own money to travel to your favorite charity, you can add those expenses to your charitable deductions (but not the value of your time or service).

The primary purpose of the trip must be for charity, with no substantial element of a vacation. According to the IRS, to qualify, you must be "on duty in a genuine and substantial sense throughout the trip."

No matter what type of transportation you use, you'll need good records of your charitable activities. Keep receipts for public transportation or mileage logs for your car (for which you can charge the standard $0.14 per mile rate for charitable organizations), as well as receipts for parking and tolls.

Tax Deductions for Medical Expenses

The IRS allows a deduction for medical expenses—but only for the portion of expenses that exceed 7.5% of your AGI. So, for example, if your AGI is $50,000, you can only deduct the portion of your medical expenses over $3,750.

If your insurance company has reimbursed you for any part of your expenses, that amount cannot be deducted. If it reimburses you in a future tax year for any portion of expenses claimed in the current year, you will need to add the reimbursem*nt (up to the amount you took as a deduction) as income in the future year.

Long-Term Care Insurance

A portion of the money you pay for long-term care insurance can also minimize your tax burden. Long-term care insurance is a deductible medical expense, and the IRS lets you deduct an increasing portion of your premium as you get older, but only if the insurance is not subsidized by your employer or your spouse’s employer.

Travel for Medical Care

You can deduct transportation and travel costs related to medical care, which means you can write off bus, car expenses (at the standard mileage rate for medical purposes of $0.22 per mile for 2023 and $0.21 per mile for 2024), tolls, parking, and lodging (but not meals)—as long as the total exceeds the 7.5% limit. Keep in mind that you can only deduct up to $50 per person per night of lodging (you can include lodging for a person traveling with you).

Other Medical Costs

Furthermore, you can deduct any additional co-payments, prescription drug costs, and lab fees as part of your medical expenses if the total exceeds the 7.5% limit. The IRS allows you to factor in common fees and services if they are not fully covered by your insurance plans, such as therapy and nursing services. In fact, the IRS’s definition of medical expenses is fairly broad and can include things like acupuncture and smoking cessation programs.

Other Tax Deductions

The TCJA rules eliminated most deductions that previously fell under the category of “miscellaneous itemized deductions.”

Many of these deductions were subject to a 2%-of-AGI threshold, meaning you could only deduct the amount that exceeded 2% of your AGI. Under the TCJA, the 2%-of-AGI threshold no longer applies. However, you can no longer deduct the following:

• Unreimbursed job expenses, such as work-related travel and union dues
• Unreimbursed moving expenses, if you had to move in order to take a new job (exception: active-duty military moving because of military orders)
• Most investment expenses, including advisory and management fees
• Tax preparation fees (except for fees to prepare Schedules C, E, or F, which are deductible business expenses)
• Fees to contest an IRS ruling
• Hobby expenses
• Personal casualty or theft losses, except in federally designated disaster areas

Here's what you can stilldeduct:

• Gambling losses up to your winnings
• Interest on the money you borrow to buy an investment
• Casualty and theft losses on income-producing property
• Federal estate tax on income from certain inherited items, such as IRAs and retirement benefits
• Impairment-related work expenses for people with disabilities
• Student loan interest (limited to the lesser of $2,500 or total interest you paid in the year)

The Bottom Line

Taxpayers can take advantage of valuable deductions available to them if they decide to itemize. Hold on to receipts for services and keep a file throughout the year so that you have a record of even the smallest expenses that you incur for business, charity, and your health. As those expenses add up, they may ultimately lower your tax bill.
