Taking a Home Office Deduction: A Great Tax Reduction Idea, If Done Right!

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? You must first pass these tests.

  1. 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.
  2. 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.
  3. 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.
  4. Principal place of business 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
