The Home Office Deduction: Who Qualifies and How to Maximize It

The home office deduction is one of the most valuable — and most misunderstood — deductions for remote workers and small business owners.

The home office deduction is one of the most valuable write-offs available to self-employed individuals and small business owners — and one of the most misunderstood. Here's what actually qualifies and how to calculate it correctly.

The Two Requirements

To claim the home office deduction, your workspace must meet two tests: it must be used regularly (not just occasionally) and exclusively for business. A dedicated office room qualifies. A kitchen table where you also eat dinner does not. A guest room with a desk in the corner does not.

Who Can Claim It

Self-employed individuals, freelancers, and small business owners can claim the home office deduction on Schedule C. W-2 employees — even those who work from home full-time — cannot claim this deduction under current tax law (the Tax Cuts and Jobs Act eliminated the employee home office deduction through 2025, and it has not been restored).

Two Calculation Methods

The simplified method allows you to deduct $5 per square foot of your home office, up to 300 square feet, for a maximum deduction of $1,500. It's easy but often leaves money on the table.

The regular method calculates the percentage of your home used for business (office square footage divided by total home square footage) and applies that percentage to actual home expenses: rent or mortgage interest, utilities, homeowner's or renter's insurance, and repairs. This method typically produces a larger deduction.

What You Can Deduct

Under the regular method, deductible expenses include rent (renters) or mortgage interest and depreciation (homeowners), utilities, internet, homeowner's insurance, and repairs or maintenance that benefit the whole home. Expenses that benefit only the office — like painting just that room — are 100% deductible.

The Depreciation Trap for Homeowners

Homeowners who claim depreciation on their home office may face depreciation recapture when they sell the home. This is manageable with proper planning but worth understanding before you claim it. Talk to a tax professional before using the regular method if you own your home.

Documentation

Measure your office space and keep records of your home expenses. If you're ever audited, you'll need to demonstrate that the space is dedicated exclusively to business. Photos of your workspace can be helpful documentation.
