Home Office Deduction Calculator
Enter your office dimensions and home expenses to see your exact IRS deduction — simplified method ($5/sq ft) or regular method (actual expenses). Includes estimated federal + self-employment tax savings.
Office Space
Business-use percentage: 12.5%
The office must be used regularly and exclusively for business. A spare room you also use as a guest bedroom does not qualify.
The home office deduction cannot exceed your net business profit for the year.
Method Comparison
IRS Requirements
- 01Exclusive use — the space must be used solely for business, not mixed with personal activities.
- 02Regular use — you must use it consistently throughout the year, not just occasionally.
- 03Principal place of business — your home must be your main business location, or where you meet clients regularly.
- 04Self-employed only — W-2 employees cannot deduct home office expenses (post-2018 TCJA).
Based on IRS Publication 587 (2024). Tax rules change; consult a CPA before filing. The regular method calculation excludes depreciation recapture and carryforward rules.
