What is the Home Office Deduction!? 

Did you know that as a small business owner if you use a portion of your home for your workspace you can get a deduction? This has to be a desgintated area! So this does not mean you can say, “I work from my kitchen table… so I’m going to write off the kitchen space.” I’m saying there needs to be a specific space…  with a desk… you get it! 

There are two different ways to do this.

  1. Simplified deduction ($5 x sq ft) maxes out at 300 sq (or $1500)

  2. Regular deduction - Many times you can almost always get more savings with the regular deduction, but it requires you track a lot more information, so many people choose to now track this. With this calculator, you can easily put all the information in one place!

So what can you deduct for your Home Office Space??

  • If you own your home - your mortgage interest & taxes (not the full mortgage payments)

  • If you rent - your rent payment

  • Utilities, Insurance, Internet, etc! 

You then take the percentage of your home office square footage of your entire home!! (don’t worry, the calculator will do this math for you!)
