Home Office Deduction: What Qualifies and How to Claim It

If you are self-employed or run a small business from home, the home office deduction can help reduce your taxable income. But the IRS has strict rules—and misunderstanding them can lead to mistakes or even audits. Following is information regarding what qualifies, how to calculate the deduction, and how to stay compliant.

What Is the Home Office Deduction?

The home office deduction allows qualifying taxpayers to deduct certain expenses related to the part of their home used exclusively and regularly for business.

It is especially useful for self-employed individuals, such as independent contractors and small business owners. Unfortunately, W-2 employees working from home (even full-time remote workers) are not eligible for this deduction, even if their employer does not provide office space.

What Qualifies as a Home Office?

To claim the deduction, your home office space must meet two key criteria:

1. Regular and Exclusive Use

The area must be used only for business and on a regular basis, such as a separate room converted to an office.

2. Principal Place of Business

Your home must be the main location where you conduct business. Conducting business includes meeting clients, doing administrative or management tasks, and performing core work functions.

If you have another regular place of business, your home office must be essential to your operations.

How to Calculate the Deduction

There are two methods for calculating the deduction:

1. Simplified Method

This method allows for deducting $5 per square foot, up to 300 square feet, for a maximum deduction of $1,500.

The benefit of the simplified method is there is no need to keep detailed records of home expenses. The drawback is that tax savings could be left on the table.

2. Actual Expense Method

Use of this method allows you to deduct both direct expenses and indirect expenses. Direct expenses are those specific to the home office (e.g., repairs and improvements made to the office area). Indirect expenses represent a percentage of actual expenses based on the area of your home used for business. This percentage is calculated by dividing the square footage of the area of your home used for business by the total square footage of your home. For example, if your home office is 200 sq. ft. and your home is 2,000 sq. ft., you can deduct 10% of qualifying expenses.

Qualifying expenses can include:

o Mortgage interest or rent
o Utilities
o Homeowners/renters insurance
o Property taxes
o Repairs/maintenance (specifically related to the office area)

What Records Should You Keep?

If you use the actual expense method, you should keep the following documentation:

• Utility bills
• Rent/mortgage statements
• Insurance documents
• Maintenance receipts
• A sketch or floor plan of your home office area

The IRS recommends maintaining records for at least three years.

Common Mistakes to Avoid

• Claiming a space not used exclusively for business
• Employees (not self-employed) trying to deduct home office
• Including personal expenses
• Overestimating square footage

Final Thoughts

The home office deduction can be a valuable tax break if you qualify and use it correctly. You should choose the calculation method that benefits you most, and you should keep supporting records if you use the actual expense method.
