Working From Home Has a Hidden Perk
If you work from home, you may be sitting on a tax deduction you’ve never claimed. The home office deduction lets eligible taxpayers reduce their taxable income based on the portion of their home used for work. It sounds simple enough, but the rules trip up a lot of people — and skipping it means leaving real money on the table.
Here’s what you actually need to know to claim it correctly.
Who Qualifies for the Home Office Deduction?
The IRS has two firm requirements. Your workspace must be used regularly and exclusively for business, and it must be your principal place of business.
That “exclusively” part matters more than most people realize. A spare bedroom where you also store holiday decorations or let guests sleep doesn’t qualify — even if you do most of your work there. The space needs to be dedicated. A true home office, a studio, a workshop: those work. A kitchen table where you sometimes answer emails does not.
One important caveat: this deduction is currently available only to self-employed individuals and business owners. Remote employees working for a company are not eligible under current tax law, a change that came into effect after the 2017 Tax Cuts and Jobs Act.
Two Ways to Calculate the Deduction
The Simplified Method
The IRS allows you to deduct $5 per square foot of your home office, up to a maximum of 300 square feet. That caps the deduction at $1,500 per year. It’s easy to calculate and requires almost no recordkeeping. If your office is 150 square feet, your deduction is $750. Done.
The Regular Method
This approach takes more work but often yields a larger deduction. You calculate what percentage of your home is used for business — say your office is 200 square feet in a 2,000 square foot home, that’s 10% — and then apply that percentage to your actual home expenses.
Those expenses can include:
- Mortgage interest or rent
- Homeowners or renters insurance
- Utilities like electricity and internet
- General home repairs and maintenance
- Depreciation (for homeowners)
If your total home expenses for the year come to $24,000, a 10% office share gives you a $2,400 deduction. That’s meaningfully more than the simplified method’s ceiling.
How to Actually Claim It
Self-employed individuals report the home office deduction on Form 8829, which feeds into Schedule C. If you’re using the simplified method, you can calculate it directly on Schedule C without filing Form 8829.
Keep documentation. If you’re using the regular method, hold onto utility bills, insurance statements, and mortgage records. The IRS can ask for them, and having a clear paper trail makes any review far less stressful.
A Few Things Worth Getting Right
Measure your office space accurately — it’s the foundation of either calculation method. If your home office also serves as your primary meeting place with clients, that strengthens your claim. And if you moved during the year, you can only count the months you were using that specific space for business.
The home office deduction isn’t complicated once you understand the ground rules. Run both calculations before you file. For many freelancers and small business owners, the regular method wins out — but the only way to know for sure is to do the math on your own numbers.
