How to Use Your Garage as Part of Your Home Office Expense

How to Use Your Garage as Part of Your Home Office Expense

For many home-based business owners, the garage can be more than just a place to park your car or store holiday decor. If you areusing your garage for business purposes—whether it’s as an office, workshop, or for inventory storage—it can be included as part of your business use of home deduction. This tax-saving opportunity allows you to deduct a portion of your home expenses related to the business use of your garage.

Here’s how to make your garage work for you and lower your taxable income in the process.


Qualifying Your Garage for the Deduction

IRS Requirements for Deducting the Business Use of Your Garage:

You must demonstrate that the garage is necessary for your business operations, not just a convenience.

Examples of Qualifying Uses:

  • Inventory Storage: Shelving or bins to store products you sell online.
  • Workshop: Space for crafting, manufacturing, or repairing items for your business.
  • Office Area: A dedicated desk or workstation in the garage.

How to Calculate the Deduction

The IRS allows you to deduct a percentage of your home expenses based on the portion of your home used for business. To include your garage:

Example:

  • Garage Size: 400 sq. ft.
  • House Size (exc. garage): 1,600 sq. ft.
  • Total Home Size for deduction: 2,000 sq. ft.
  • Business Use Percentage: 400 ÷ 2,000 = 20%

This means you can deduct 20% of eligible home expenses.


Eligible Expenses You Can Deduct

Once you’ve calculated the business use percentage, you can apply it to the following expenses:

Example:

  • Annual Home Expenses: $24,000 (rent, utilities, taxes, etc.)
  • Business Use Percentage: 20%
  • Deduction: $24,000 x 20% = $4,800

Special Considerations for Garages

1. Dual-Purpose Garages

If your garage is used for both business and personal purposes (e.g., storing inventory and parking your car), you’ll need to allocate the space used for business.

Example:

  • Garage Size: 400 sq. ft.
  • Business Area: 200 sq. ft. (50% of the garage)
  • Total Home Size including garage: 2,000 sq. ft.
  • Business Use Percentage: 200 ÷ 2,000 = 10%

2. Improvements for Business Use

If you make upgrades to your garage specifically for your business—like installing shelves for inventory or adding insulation for a workshop—those costs may be fully deductible.

3. Documentation is Key

To claim the deduction, you’ll need to keep detailed records, including:

  • Photos of your garage setup
  • Floor plans showing the business area
  • Receipts for expenses and improvements
