Quick Answer
Home office depreciation lets you deduct your business percentage of your home's depreciation over 39 years (commercial) or 27.5 years (residential). For a $400,000 home with 10% business use, you can deduct approximately $1,455 annually, but must recapture this depreciation when you sell your home.

Understanding home office depreciation
Depreciation is often the largest single component of the actual expense home office deduction, but it's also the most complex. According to [IRS Publication 946](https://www.irs.gov/pub/irs-pdf/p946.pdf), you can depreciate the business portion of your home's adjusted basis over 39 years using the straight-line method.
Step 1: Calculate your home's depreciable basis
Your basis for depreciation is typically the lower of:
Example: $400,000 home calculation
Step 2: Apply depreciation schedule
Residential property used for business follows MACRS (Modified Accelerated Cost Recovery System):
Annual depreciation calculation:
$32,000 ÷ 39 years = $821 per year
Depreciation timing and methods
First-year partial depreciation: If you start using your home office mid-year, you can only claim a partial year's depreciation based on the month you started.
Key factors affecting your depreciation:
Depreciation recapture when you sell
This is where depreciation gets tricky. When you sell your home, you must "recapture" (pay tax on) the depreciation you claimed, even if you qualify for the $250,000/$500,000 home sale exclusion.
Example recapture calculation:
What you should do
Track your depreciation carefully each year and maintain detailed records of your home's basis, improvements, and business use percentage. Consider whether the annual tax savings justify the future recapture tax. Use our [deduction-finder](tool) to calculate your optimal depreciation strategy based on your specific situation.
Key takeaway: Home office depreciation typically provides $800-2,000 in annual deductions for most freelancers, but creates a 25% recapture tax on the total depreciation when you sell your home.

Best for freelancers who recently bought homes and are setting up home offices
Setting up depreciation for your new home office
As a new homeowner, you have a clean slate for establishing your depreciation basis and business use percentage. This is the optimal time to make strategic decisions about your home office setup.
Establishing your depreciable basis:
First-year considerations:
If you bought your home and started your business mid-year, you'll use the mid-month convention for depreciation. Starting your home office in July means you can claim 5.5 months of depreciation in year one.
Strategic timing for improvements:
Capital improvements made specifically for your home office (built-in desks, electrical upgrades, flooring) can be added to your depreciable basis rather than expensed immediately. This spreads the deduction over 39 years but may provide better overall tax benefits.
Example for $350,000 new home:
Document everything from day one – your future self will thank you when tax season arrives.
Key Takeaway: New homeowners can establish optimal depreciation basis by properly documenting purchase price, improvements, and business use from the start.

Best for consultants whose office space requirements change over time
Managing depreciation with changing business space
Consultants often need to adjust their home office space as their business grows or changes. This affects your depreciation calculations and requires careful record-keeping.
When business use percentage changes:
Example: Expanding office space
Converting non-business space:
If you convert a bedroom to office space, the depreciable basis for that space begins when you start using it for business, not when you bought the house. Use fair market value at conversion date if it's higher than your original cost basis.
Temporary vs. permanent changes:
Documentation requirements:
Consultants with evolving space needs should review their depreciation calculations annually and adjust for any permanent changes in business use percentage.
Key Takeaway: Consultants must recalculate depreciation whenever business use percentage changes permanently and maintain detailed documentation of space modifications.
