The Home Office Deduction, Explained (Without the Audit Anxiety)
The home office deduction is one of the most misunderstood — and most avoided — write-offs for the self-employed. Used correctly, it's completely legitimate.
Who actually qualifies
To claim the deduction, you must use part of your home regularly and exclusively for business, and it must be your principal place of business.
'Exclusively' is the word that trips people up. The spare room that doubles as a guest room usually doesn't qualify, but a dedicated office you use only for work does.
Two ways to calculate it
The simplified method deducts $5 per square foot, up to 300 square feet — a maximum of $1,500. It's quick and requires almost no records.
The regular method deducts the actual percentage of home expenses tied to your office's share of the home: rent or mortgage interest, utilities, insurance, and depreciation. It takes more record-keeping but often produces a larger deduction.
Employees generally can't claim it
Since the 2018 tax law changes, W-2 employees can no longer deduct a home office — even when they work remotely full-time. This deduction is for the self-employed, independent contractors, and business owners.
It's not a red flag when done right
The home office deduction earned its scary reputation decades ago. Today it's routine when you meet the rules and keep reasonable records.
