Home Office Deduction

Average Value: $1,500 - $5,000+

The home office deduction allows self-employed individuals to deduct expenses for the business use of their home. Whether you work from a dedicated room or a specific area, you can potentially deduct rent, utilities, insurance, and more. Two methods exist: simplified ($5/sq ft, max $1,500) and actual expenses (proportional share of home costs).

Requirements

Space must be used regularly and exclusively for business
Must be your principal place of business OR used for client meetings
Only available for self-employed (not W-2 employees)
Calculate business-use percentage: office sq ft ÷ home sq ft

How to Claim

1Measure your dedicated workspace square footage

4Actual method: Gather rent/mortgage, utilities, insurance, repairs records

Frequently Asked Questions

Can my home office be in my living room?

Yes, if you have a dedicated space used exclusively for business. A desk area qualifies if it's only used for work, even if it's in a larger room.

What if I also work at client sites?

Your home office can still qualify as your principal place of business if you use it for admin tasks and have no other fixed location.
