When Medical Expenses are — and aren’t — Tax Deductible

If you had significant medical expenses last year, you may be wondering what you can deduct on your 2025 income tax return. Income-based thresholds and other rules can make it hard to claim the medical expense deduction. At the same time, more types of expenses may be eligible than you might expect.

Limits on the deduction

Medical expenses are deductible only if they weren’t reimbursable by insurance or paid via tax-advantaged accounts (such as Flexible Spending Accounts or Health Savings Accounts). In addition, they’re deductible only to the extent that, in aggregate, they exceed 7.5% of your adjusted gross income (AGI).

For example, if your 2025 AGI was $100,000, your eligible medical expenses during the year would have to total more than $7,500 for you to claim the deduction — and only the amount in excess of that floor would be deductible. If you had $10,000 in eligible expenses, your potential deduction would be $2,500.

In addition, medical expenses are deductible only if you itemize deductions. For itemizing to be beneficial, your itemized deductions must exceed your standard deduction. Due to changes under the Tax Cuts and Jobs Act that were made permanent […]

Review Your Business Expenses Before Year End

Now is a good time to review your business’s expenses for deductibility. Accelerating deductible expenses into this year generally will reduce 2025 taxes and might even provide permanent tax savings. Also consider the impact of the One Big Beautiful Bill Act (OBBBA). It makes permanent or revises some Tax Cuts and Jobs Act (TCJA) provisions that reduced or eliminated certain deductions.

“Ordinary and necessary” business expenses

There’s no master list of deductible business expenses in the Internal Revenue Code (IRC). Although some deductions are expressly authorized or excluded, most are governed by the general rule of IRC Section 162, which permits businesses to deduct their “ordinary and necessary” expenses.

An ordinary expense is one that is common and accepted in your industry. A necessary expense is one that is helpful and appropriate for your business. (It doesn’t have to be indispensable.) Even if an expense is ordinary and necessary, it may not be deductible if the IRS considers it lavish or extravagant.

OBBBA and TCJA changes

Here are some types of business expenses whose deductibility is affected by OBBBA or TCJA provisions:

Entertainment. The TCJA eliminated most deductions for entertainment expenses beginning in 2018. However, entertainment expenses […]

Startup Costs and Taxes: What You Need to Know Before Filing

The U.S. Census Bureau reports there were nearly 447,000 new business applications in May of 2025. The bureau measures this by tracking the number of businesses applying for an Employer Identification Number.

If you’re one of the entrepreneurs, you may not know that many of the expenses incurred by start-ups can’t currently be deducted on your tax return. You should be aware that the way you handle some of your initial expenses can make a large difference in your federal tax bill.

How to treat expenses for tax purposes

If you’re starting or planning to launch a new business, here are three rules to keep in mind:

Start-up costs include those incurred or paid while creating an active trade or business or investigating the creation or acquisition of one.
Under the tax code, taxpayers can elect to deduct up to $5,000 of business start-up costs and $5,000 of organizational costs in the year the business begins. As you know, $5,000 doesn’t go very far these days! And the $5,000 deduction is reduced dollar-for-dollar by the amount your total start-up or organizational costs exceed $50,000. Any remaining costs must be amortized over 180 months […]

Pay Attention to the Tax Rules if You Turn a Hobby into a Business

Many people dream of turning a hobby into a regular business. Perhaps you enjoy boating and would like to open a charter fishing business. Or maybe you’d like to turn your sewing or photography skills into an income-producing business.

You probably won’t have any tax headaches if your new business is profitable over a certain period of time. But what if the new enterprise consistently generates losses (your deductions exceed income) and you claim them on your tax return? You can generally deduct losses for expenses incurred in a bona fide business. However, the IRS may step in and say the venture is a hobby — an activity not engaged in for profit — rather than a business. Then you’ll be unable to deduct losses.

By contrast, if the new enterprise isn’t affected by the hobby loss rules, all otherwise allowable expenses are deductible, generally on Schedule C, even if they exceed income from the enterprise.

Important: Before 2018, deductible hobby expenses could be claimed as miscellaneous itemized deductions subject to a 2%-of-AGI “floor.” However, because miscellaneous deductions aren’t allowed from 2018 through 2025, deductible hobby expenses are effectively wiped out from 2018 through 2025.

What Types of Expenses Can’t Be Written Off By Your Business?

If you read the Internal Revenue Code (and you probably don’t want to!), you may be surprised to find that most business deductions aren’t specifically listed. For example, the tax law doesn’t explicitly state that you can deduct office supplies and certain other expenses. Some expenses are detailed in the tax code, but the general rule is contained in the first sentence of Section 162, which states you can write off “all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business.”

Basic definitions

In general, an expense is ordinary if it’s considered common or customary in the particular trade or business. For example, insurance premiums to protect a store would be an ordinary business expense in the retail industry.

A necessary expense is defined as one that’s helpful or appropriate. For example, let’s say a car dealership purchases an automated external defibrillator. It may not be necessary for the operation of the business, but it might be helpful and appropriate if an employee or customer suffers cardiac arrest.

It’s possible for an ordinary expense to be unnecessary — but, in order to be deductible, an expense […]
