Can You Claim a Home Office Tax Deduction?

The home office tax deduction lets eligible taxpayers deduct certain home-related expenses tied to business use when they file their taxes. Whether you qualify depends on factors such as whether you are self-employed or work remotely, whether the area is used regularly and only for business, and several other IRS rules.

Intuit TurboTax explains the basics, along with IRS requirements, to help determine whether the home office deduction is available to you.

Are you remote or self-employed?

Remote workers generally cannot claim a tax write-off for a workspace at home simply because they work from home, whether by choice or necessity. Self-employed taxpayers, however, may be able to benefit from the home office deduction.

Before the Tax Cuts and Jobs Act changed the rules, employees who worked remotely could deduct unreimbursed job expenses, including qualifying home office costs. Those employee business deductions were suspended for several years and later permanently removed under the One Big Beautiful Bill, which ended the deduction for unreimbursed employee business expenses.

In other words, if you are an employee working from home for an employer rather than a business owner who is self-employed or an independent contractor, you do not qualify for the home office tax deduction.

What counts as a home office?

A home office must be either the main place where you conduct business or a location where you regularly meet with clients, patients or customers. To qualify, the space must be used exclusively for business. The area can be part of a house, apartment, mobile home, condominium, boat or another similar structure used on a regular basis for business.

An unattached structure on your property, such as a barn, studio, greenhouse or garage, can also qualify. In that situation, the structure does not need to be your principal place of business or a place where you meet clients or customers, but it still must be used regularly and exclusively for business.

Some uses of space inside the home, such as storage or a daycare arrangement, may also qualify for tax purposes.

The exclusive and regular use test

Exclusive use means the space is used only for business, all the time. Exceptions apply for storage of inventory or samples and for a home used as a daycare, but the regular-use requirement still applies in those cases.

To show how strict the rule is, the IRS gives an example of a home office used full time, 10 hours a day, seven days a week. If children use that office for homework, the exclusive-use requirement is broken and the deduction is lost.

Another example involves an attorney who uses a room for work but also as a family den. That shared use fails the exclusive test, so the room does not qualify for the deduction.

What qualifies as a business?

Whether your activity qualifies for the deduction depends on what you do in the home office and how regularly you do it. More substantial activity, including the time and effort involved and the income produced, makes it more likely you will meet the standard.

Profit is not the only factor, though earning money from the activity is required to claim the deduction.

For instance, if you use your living room only to manage your personal investment portfolio, you cannot claim a home office deduction because investing is not considered a business activity. On the other hand, taxpayers who use a home office solely to manage rental properties may qualify as property managers rather than investors.

What can you deduct?

Business-use deductions for your home may include the business portion of:

• Real estate taxes
• Mortgage interest
• Rent
• Casualty losses
• Utilities
• Insurance
• Depreciation
• Maintenance
• Repairs

In general, you cannot deduct expenses tied to parts of the home that are not used for business, such as lawn care or repairs made to a workout room.

How much can you deduct for a home office?

Calculating the deduction is often simpler than it sounds. Eligible taxpayers can choose between two methods to figure out the amount.

Actual expense method

Under the actual expense method, taxpayers must calculate the actual costs tied to the home office. This was the required method for tax years before the simplified option existed.

Using this approach, the deduction is based on the percentage of the home used exclusively for business. You determine how much of your home the office occupies and apply that share to qualifying expenses.

For example, if a room used for business is 200 square feet in a 2,000-square-foot house, the business-use percentage is 10%.

That means 10% of eligible expenses such as mortgage interest, depreciation and utilities may be deducted. If those expenses total $4,500, the deduction would be about $450.

Here is the basic math:

% business expenses x total expenses = home office expenses

0.10 x $4500 = $450

Simplified method

The simplified method reduces recordkeeping by letting qualified taxpayers multiply a set rate by the allowable square footage instead of calculating actual expenses.

This method uses a rate of $5 per square foot of home office space, up to 300 square feet, for a maximum deduction of $1,500.

For example, if you use 200 square feet for business, the simplified deduction would be $1,000.

Even though the simplified method may produce a larger deduction in this example, that is not always true. The result depends on your actual expenses and which costs apply to the part of the home used for business. Repairs made elsewhere in the house, for example, cannot be included.

Important considerations

No matter which method you use, you cannot claim business expenses beyond the gross income limit tied to the home office deduction.

It is also important to review whether your business use of the home still meets the rules each year. Depreciation can affect the calculation, so keeping detailed records matters because eligibility can change from one year to the next.
