Cloud-based applications, extensive communication channels, and other new technologies make it easier to run your business out of your home. If you qualify, many home business expenses are deductible. Think you might qualify?

Trade or Business Use Test

To qualify for business use of your home you must use part of your home for a qualified trade or business. This profit seeking activity must not be a hobby in the eyes of the IRS.

Exclusive Use Test

You must use part of your home exclusively for your business activity. Blending personal use within the same space as your business activity can disallow the business use of home deductions, however, there does not need to be a permanent barrier between this space and the rest of the house.

Regular Use Test

In addition to having a qualified business activity in an exclusive area of your home, you must also use it regularly for your business activity. The IRS applies judgment in this area to determine the facts and circumstances around what it deems to be regular use.

Primary Place of Use Test

To deduct your home office expenses, the home location must also be your principal place of business. That does not mean there cannot be other business locations, just that your home office must be your primary location. You might also have multiple business activities. In this case, you could meet the test for one of your businesses to qualify to take the deductions. With multiple locations, the considering factors are:

  • The relative importance of the activities performed at each location
  • The amount of time spent at each location
  • The primary place used exclusively and regularly for administrative or management activities
  • Whether there are other fixed locations for business use

Types of Deductible Expenses

This chart from the IRS gives some direction on the types of expenses that are deductible. As always, proper substantiation is required to take the deduction, so keep all receipts and statements in an organized fashion.

Expense Description Deductibility
Direct Expenses only for the business part of your home (Examples: Painting or repairs only in the area used for business) Deductible in full. (Exception: May be only partially deductible in a daycare facility)
Indirect Expenses for keeping up and running your entire home(Examples: Insurance, utilities, and general repairs) Deductible based on the percentage of your home used for business.*
Unrelated Expenses only for the parts of your home not used for business(Examples: Lawn care or painting a room not used for business) Not Deductible
* Subject to the deduction limit
