Working from home comes with a valuable tax benefit: the home office deduction. If you use part of your home exclusively and regularly for business, you may be able to deduct a portion of your housing costs. The question is which method to use — the simplified method or the regular (actual expense) method. Each has real tradeoffs worth understanding.
Who Qualifies for the Home Office Deduction?
To claim any home office deduction, you must meet two IRS requirements:
- Exclusive use: The space must be used only for business — not a guest room that doubles as your office.
- Regular use: You must use it consistently, not just occasionally.
Self-employed people and sole proprietors can deduct home office costs on Schedule C. W-2 employees cannot claim this deduction since the Tax Cuts and Jobs Act of 2017 suspended it through 2025.
The Simplified Method
The simplified method lets you deduct $5 per square foot of your home office space, up to a maximum of 300 square feet — so the maximum deduction is $1,500 per year.
Example: If your home office is 200 square feet, your deduction is 200 × $5 = $1,000.
Pros of the Simplified Method:
- No depreciation to calculate or recapture when you sell your home
- Much easier recordkeeping — just measure the space
- No proration of actual home costs needed
Cons of the Simplified Method:
- Maximum deduction of $1,500 regardless of actual costs
- May significantly understate your real deduction if you have high housing costs
The Regular (Actual Expense) Method
The regular method calculates the actual percentage of your home used for business and applies that percentage to your real housing costs.
The percentage is typically: Office square footage ÷ Total home square footage
Deductible expenses include:
- Rent (if you rent) or mortgage interest (if you own)
- Homeowners or renters insurance
- Utilities (electricity, gas, internet)
- Home repairs and maintenance (that affect the whole home)
- Depreciation (if you own your home)
Example: Your home is 2,000 sq ft, your office is 300 sq ft (15%), and your annual home costs total $24,000. Your deduction is 15% × $24,000 = $3,600.
Pros of the Regular Method:
- Often produces a much larger deduction for people with high housing costs
- Captures real costs including depreciation
Cons of the Regular Method:
- Requires detailed recordkeeping of all home expenses
- Depreciation creates potential “recapture” tax when you sell your home
- More complex to calculate (usually requires IRS Form 8829)
Depreciation Recapture: The Hidden Cost
When you use the regular method and claim depreciation on your home, the IRS requires you to “recapture” that depreciation when you sell the home — meaning you’ll pay tax on it at a rate up to 25%. This doesn’t make the regular method wrong, but it’s a factor to discuss with your accountant, especially if you own your home.
The simplified method avoids this entirely — no depreciation means no recapture.
Which Method Should You Choose?
Here’s a straightforward way to decide:
- If your home office is small (under 200 sq ft) and you have low housing costs: the simplified method may be close enough — and far simpler.
- If you have high rent or mortgage, utilities, and a larger office space: the regular method likely wins by a significant margin.
- If you own your home: weigh the depreciation recapture risk against the larger current deduction.
You can switch between methods year to year — there’s no requirement to use the same method each year. However, if you use the simplified method one year, you cannot carry forward any deduction that was limited due to your business income that year.
The Income Limitation Rule
With either method, your home office deduction cannot exceed your net business income for the year. If your business only earned $800 but your home office deduction calculates to $2,000, you can only deduct $800 — and with the regular method, you can carry the remaining $1,200 forward to next year. With the simplified method, you lose any unused portion.
Bottom Line
For most self-employed people in higher-cost housing markets, the regular method produces a much larger deduction — often 2–3 times what the simplified method would yield. If you rent and don’t have depreciation concerns, the regular method is usually worth doing. If you own your home and want simplicity, the simplified method eliminates depreciation complications.
Take 15 minutes to calculate both numbers before filing. The difference is commonly $1,000–$3,000 per year.
