Five Rules That Determine Your Home Office Deduction
Satisfy these first, then choose between the two methods.
02
Principal Place of Business
Your home office must be your principal place of business, or where you regularly meet clients, or where you conduct substantial administrative or management activities.
03
Simplified Method ($5/sq ft)
Deduct $5 per square foot up to 300 sq ft ($1,500 cap). No Form 8829, no depreciation, no need to track individual expenses. Available regardless of business income.
04
Regular Method (Actual Expenses)
Allocate actual home expenses (mortgage interest, property tax, utilities, maintenance, depreciation) based on the business-use percentage. Requires Form 8829.
05
Deduction Cannot Exceed Business Income
Under the regular method, the home office deduction cannot create or increase a net operating loss. Carry forward unused deductions to future years.

How to Claim the Home Office Deduction in 2026
Six steps from eligibility check to filing.
- Confirm eligibility. Verify your space meets the exclusive-and-regular-use test and is your principal place of business.
- Measure your space. Record the square footage of your home office and your full home to calculate the business-use percentage.
- Pick a method. Use our comparison calculator to see whether simplified ($5/sq ft) or regular (actual expenses) gives a larger deduction.
- If using simplified. Multiply sq ft by $5 (max $1,500). Report the amount directly on Schedule C, line 30. No additional forms needed.
- If using regular. Complete Form 8829 with your actual home expenses and business-use percentage. Transfer the deductible amount to Schedule C.
- Retain records. Keep a floor plan, expense receipts, and a contemporaneous log of business use. Store for at least 3 years.
Quick decision guide: If your home office is 300 sq ft or larger and you have a mortgage, the regular method usually wins. For smaller spaces or renters, the simplified method is almost always the better choice. Run both numbers with our free calculator.
Six Home Office Deduction Mistakes to Avoid
These are the errors the IRS looks for most often.
1. Failing the exclusive-use test
If your office doubles as a guest room, storage, or family space, the IRS will disallow the entire deduction. Dedicate the space 100% to business.
2. Using the simplified method when regular yields more
High-income contractors with large homes and mortgages often leave thousands on the table by defaulting to the $1,500 cap. Always compare.
3. Forgetting to include depreciation
Under the regular method, you can depreciate the business portion of your home. This is often the single largest deduction component.
4. Not keeping a floor plan
The IRS may ask for a floor plan showing which space is used for business. A simple sketch with square dimensions is sufficient.
5. Deducting lawn care and personal repairs
Only expenses that benefit the business portion are deductible. General lawn care or personal kitchen upgrades don't qualify.
6. Switching methods year-to-year without records
You can switch methods annually, but if you use the regular method in any year, you must recapture depreciation when you sell your home. Document your choice each year.

Yes. The home office deduction remains fully available for self-employed workers and 1099 contractors in 2026. Employees (W-2) can no longer claim this deduction following the 2017 TCJA, but self-employed individuals retain it.
The simplified method lets you deduct $5 per square foot of your home office, up to 300 square feet ($1,500 maximum). No Form 8829 is required, and you don't need to calculate actual expenses.
To claim the deduction, your home office must be used exclusively and regularly for business. This means the space cannot be used for personal activities. A guest bedroom that doubles as an office fails the exclusive-use test.
The simplified method is free math and guarantees a $1,500 deduction. Use the regular method when your actual home office expenses (mortgage interest, utilities, depreciation) multiplied by your business-use percentage exceed $1,500.
Divide the square footage of your home office by the total square footage of your home. For example: 200 sq ft office / 2,000 sq ft home = 10% business use. Apply this percentage to all home expenses.
Yes, but the home office deduction cannot create or increase a business loss for the regular method. The simplified method has no such restriction and can be used even if your business shows a net loss for the year.
