About the Home Office Deduction

Tax clients ask me all the time about taking a home office deduction. That topic has come up even more often since COVID-19 has so many people working at home. However, everyone with an office at home isn’t eligible for a home office deduction, even if she or he owns a business. Lots of rules apply. It can be pretty confusing. 

So, let’s “un-confuse” the topic:

  1. Who is eligible for a home office deduction?

Only individuals who own a business are eligible for the deduction. Yes, some employees used to be eligible under special circumstances, but those rules changed at the end of 2017. Now, only business owners who use space in her or his home exclusively and regularly to substantially conduct business operations can consider taking a home office deduction. No non-business activity can be conducted in a home office. That means no personal items in the home office, even clothes in the closet.

  1. What home expenses can be deducted?

Deductible home office expenses are either direct or indirect, based on the expense type and business percentage of the home used for business. The most common method used to calculate the business percentage is dividing the square footage used exclusively for business by total square footage. Shared spaces, like hallways, cannot be included in office space.  

  • Direct Expenses: Expenses that benefit only the home area that is exclusively used for business, such as painting or repairs in the home office, are direct expenses that are fully deductible.
  • Indirect Expenses: Expenses for keeping up and running the entire home, such as the mortgage interest, real estate taxes, insurance, utilities, and general repairs are deductible based on the business use percentage, described above.

Expenses to maintain the non-living home space, such as lawn care, are not deductible. For business owners who don’t want to hassle with tracking all the various home office expenses, the IRS has a Simplified Option that allows a standard deduction of $5 per square foot, limited to 300 square feet.  

Eligibility for a home office deduction is determined by a lot of rules that can be confusing. We address the basics here, but there’s more to it. Details and examples are on the IRS website at https://www.irs.gov/businesses/small-businesses-self-employed/home-office-deduction.
