Quick answer
The home office deduction has two methods. The simplified method gives $5 per square foot for up to 300 square feet (a $1,500 maximum). The regular method deducts your business-use percentage of actual home costs, such as rent, utilities and insurance, on Form 8829.
Enter your numbers below to see which method deducts more. Example: a 150 sq ft office in a 1,200 sq ft apartment with $21,000 of yearly costs gives $750 with the simplified method but $2,625 with the regular method.

Do you qualify?
To claim a home office as a freelancer, the space must be used:
- Regularly and exclusively for business. A desk in the corner of the guest room counts only if that area is used for nothing else.
- As your principal place of business, or a place where you meet clients, or a separate structure used for business.
W-2 employees cannot claim this deduction on their federal return. Full rules in our home office deduction guide.
Simplified vs regular method
- Simplified: multiply the office square footage (up to 300) by $5. No depreciation, no Form 8829 calculations, and you can still deduct all mortgage interest and property tax as itemized deductions.
- Regular: office square feet divided by total home square feet gives your business-use percentage. Apply it to rent or mortgage interest, property tax, utilities, insurance, repairs and depreciation.
The regular method usually wins for renters in expensive areas and for larger offices. The simplified method wins when costs are low or you want less paperwork. You can switch methods from year to year.
Worked example
Ana rents a 1,200 sq ft apartment and uses a 150 sq ft room only as her design studio.
- Business-use percentage: 150 / 1,200 = 12.5%
- Yearly costs: $18,000 rent + $2,400 utilities + $600 renter’s insurance = $21,000
- Regular method: $21,000 x 12.5% = $2,625
- Simplified method: 150 x $5 = $750
The regular method gives Ana $1,875 more in deductions. Her internet and phone are separate: see deducting phone and internet.
Frequently asked questions
Can the deduction create a loss?
No. Both methods are limited to the gross income from your business minus other expenses. With the regular method, the unused amount carries forward to next year.
Does depreciation matter if I own my home?
Yes. Homeowners using the regular method must claim depreciation on the office part of the home, which can be recaptured and taxed when you sell. Ask a tax professional before you sell.
What if I moved or started mid-year?
Count only the months the office was used for business. The calculator prorates both methods by the months you choose.
Where do I report it?
On Schedule C, line 30. With the regular method you also file Form 8829. See how to fill out Schedule C and the full self-employed deductions list.
