You must report any profit or loss from your business to the Internal Revenue Service (IRS) as well as to your state taxing authority. To file your taxes, download the necessary forms and instructions from the IRS website. Then figure out if you qualify to take a business deduction for your home office. Because the tax code is complicated, you are advised to seek out the help of an accountant if you have any questions or problems.

Calculating Your Home Office Deduction

  1. You cannot take a home office deduction simply because you work in your home. Instead, you must meet other criteria. Read IRS publication 587 to check if you qualify. [11] Generally, the following must be true to qualify:
    • You must use the home office regularly and exclusively for business. For example, your kitchen table wouldn’t qualify as a “home office” because you also eat in the kitchen. However, if you use an extra room as your office, then you can typically take a home office deduction. [12]
    • The home office must be your principal place of business. This means that you use the home office “substantially” and “regularly” as your base of operations.
  2. There are two different ways to calculate the home office deduction. You can calculate using the “simplified” method or by calculating “actual expenses” (which his also called the “regular” method).
    • Under the simplified method, you multiply the square feet used by $5. You can only claim up to 300 square feet. [13] Accordingly, if your home office is 200 square feet, then you can claim $1,000 as a deduction.
    • Under the regular (“actual expenses”) method, you can deduct mortgage interest, insurance, repairs, utilities, and depreciation. Generally, the amount you can claim will be based on the percentage of your home devoted to the business. [14]
  3. Complete this form if you are using the “actual expenses” method for calculating your home office deduction. You can download the form and instructions from the IRS website. [15] The form will ask for the following information: [16]
    • area of home used for business
    • total area of home
    • mortgage interest
    • real estate taxes
    • insurance
    • rent
    • repairs and maintenance
    • utilities
    • depreciation of your home
