Home Office Deductions: How to Claim for Maximum Impact

This article has been reviewed by tax expert Erica Gellerman, CPA.

Today there are lots of ways to make money working from home. Many small business owners operate out of their home and increasing numbers of workers are opting to freelance full-time, and others choose to take jobs that allow them to work remotely, rather than commute into an office every day. Even employers that operate office space are more amenable to letting their employees work from home from time to time. All of which is to say that working from home—and claiming a home office deduction—is more common now than it ever has been before.

Can You Claim Home Office Deductions?

Before we dive into how to claim home office deductions, the first business accounting question to ask yourself is: “Can I claim a home office deduction?” When it comes to this tax deduction, the IRS can be pretty strict on who qualifies. So to avoid an audit and get the most out of the home office deduction, let’s review what it takes to qualify:

Exclusive and Regular Use

In order to be eligible for a home office deduction, the space you’re using for your business must only be used for your business. This can be the hardest qualifier to meet, and the IRS is pretty serious about it.

Say you use a separate room or multiple rooms in your house as your office for 40 hours of the work week. If you only use that part of your house for business, you’re in the clear. But if your significant other comes into the space to use your desk for a few hours out of that week, your exclusivity eligibility goes out the door.

While the IRS can be very strict when it comes to this eligibility requirement, they do use a common rule of thumb: You’ll generally meet the exclusivity requirement if personal activities take place in your home office just as much as they would in a regular, communal office. This means that the occasional personal phone call in your business’s home office is fine.

If you meet the exclusivity requirement, odds are you’ll meet the regularity home office deduction requirement for your business taxes. There is no specific rule set to how regularly you use the space, but if you use the space at least a few hours a day, you’ll probably be fine. If you’re really not in space that much each week, you probably won’t qualify.

There are two exceptions to the exclusivity rule. The first exception is if you run a daycare or elderly care center in your home. For example, if, as part of your business, you have children in your home from 8 a.m. to 4 p.m. every day, but make use of the space for personal activities from 4 p.m. on, you can still claim a home office deduction (granted you’ve met your state’s licensing requirements). The second exception is for business owners who dedicate a portion of their home to store their business’s inventory or products.

Principal Place of Business

The next requirement for a home office deduction is pretty simple. While your home office doesn’t have to be the only place you do business, it does have to be your principal place of business, aka the primary place you do business—meaning you bill customers, perform regular administrative tasks, or keep books in your home office. This also could mean that your home office is where you regularly meet clients and customers.

How to Claim Home Office Deductions

There are two ways to claim home office deductions: The simplified square foot calculation or the actual expense deduction.

Here’s what you need to know about both:

The Simplified Method

The simplified method lives up to its name. All you have to do is multiply the square footage of your home office by $5. The catch is that the maximum amount you can write off is $1,500. If you’re just starting out or using your office for a side hustle, this might be the right method for you.

The Regular Method Using Form 8829

If your home office expenses are more than $1,500, you’ll want to use Form 8829. To apply this method, calculate percentages of the various expenses you want to claim. This is likely a better option for more mature or complex home businesses.

As part of this process, expenses are classified as direct or indirect. Direct expenses are the expenses that are clearly and definitively tied to the space that you use as a home office. Examples include completed painting projects or renovations that were exclusively done for your home office. You may claim 100% of direct expenses.

Indirect expenses are costs related to the home or property that houses your home office. These include things like utilities and mortgage or rent payments. You may only claim a percentage of indirect expenses, which is the total square footage of your home divided by the square footage of your home office.

One limit to the regular method is that you can’t claim more on a home business tax deduction than you earned while working in your home office. Your claim must be proportional to the time you spend working in your home office.

Which Is Better—the Simplified or Regular Method?

It depends. Factors to take into consideration include:

  • The Size of Your Home Office: If your office is 300 square feet or less, the simplified method is likely best. But if you’ve got a bigger office, you could get a larger deduction using the regular method. Know that there’s no limit to the size of home office using Form 8829.
  • Mortgage and Rental Rates: If you live in an area where the cost of rent or homeownership is traditionally high, you might be able to get a larger deduction using the regular method.
  • Home Depreciation: For the simplified method, you can’t deduct depreciation. Real estate taxes and the interest on your mortgage can be claimed using Schedule A. If your home has depreciated, you may want to consider using Form 8829. And if you ever sell your home at a profit, this deduction will be taken into consideration in calculating your resulting tax liabilities.
  • Record Keeping: If this isn’t your forté, the simplified method is for you. The regular method requires that you keep detailed records of each expense. (Even if you don’t send the receipts in with your filing, you need to keep them on hand for a few years, just in case.)
  • How Much you Like Filling out Forms. The form for the simplified method has six lines within a Schedule C. Compare that to that Form 8829, which has 43 lines to complete. When you use Form 8829, it must accompany your Schedule C when you complete your filing.

How to Claim Home Business Deductions: The Definitive Solution

The best way to know which method to use is to run the numbers. Add up your home office expenses. If they’re more than $1,500, consider using the regular method. If not, use the simplified method.

As your business grows and your calculations become more complicated, tools like QuickBooks, QuickBooks Online, or QuickBooks Self-Employed can help you streamline your financial processes (and record keeping). If you’re not one for mainstream solutions, there are also many other tools available like Xero or Sage, for example.

Finding yourself a trusted accountant or bookkeeper can also be invaluable. As many firms switch to the cloud, they can suggest a primary small business accounting software and a range of key apps for functions like time tracking, data entry, payables and receivables, and payroll.

The better your tools and processes, the more you’ll be able to maximize your deductions.

Home Office Deductions for Employees

If your employer allows you to work from home or you’re a remote worker, you can no longer use the home office deduction. Employees who worked remotely used to be able to take home office deductions, but the Tax Cuts and Jobs Act eliminated this deduction for tax years 2018 – 2025.

Home Office Deductions: Other Points to Keep in Mind

In all of this, it’s important to note how the IRS defines a home office. The two key concepts are regular and exclusive use. Regular means that you must routinely use this portion of your home for business. Exclusivity is a bit less tangible. In essence, it implies that the area where you work must be identifiable as a space used exclusively for business.[1]

A home office doesn’t have to be a room within your home. It can also be a garage or outbuilding like a studio or shed.

Home Office Deductions: FAQs

Need to know more about claiming home office deductions? Here are some frequently asked questions about this small business tax deduction.

1. Am I Locked in Once I Pick a Method?

No, you are not. You may use either method in a given filing year. If the simplified works better one year, use it. If regular works better the next, it’s your call. The only restriction is that you can’t use both methods in the same filing year. It has to be one or the other.

2. Am I More Likely to Get Audited When I Claim a Home Office Deduction?

The risk is likely no larger than for any other type of deduction you claim. Studies have shown that there’s no conclusive evidence of a greater risk. But, if you do a quick search, you see a lot of concerning headlines. In the end, if you’ve been honest (which you absolutely should be) and kept good records, you don’t have much to fear from an IRS audit anyhow.

3. What If I Don’t Fit the Textbook Definition of Home Office?

On a general level, caregiving is a yes and rental or hospitality use is a no. If you run licensed home daycare or provide elder care, you may take the home office deduction using either method.

On the other hand, any expenses related to any space in your home that you use as a hotel, motel, inn, or similar business do not fall under the home office deduction.
