📐 How This Is Calculated

Actual Expense Method

Business Use % = Home Office Sq Ft ÷ Total Home Sq Ft
Deductible Amount = Total Home Expenses × Business Use %

Some expenses (like a direct office repair) are 100% deductible. Others (heat, rent, insurance) are pro-rated by the business use percentage.

Simplified Method (IRS Rev. Proc. 2013-13)

Deduction = min(Office Sq Ft, 300) × $5
Maximum deduction = $1,500 (300 sq ft × $5)

The simplified method caps at 300 sq ft and $1,500/year. No depreciation. No record-keeping of home expenses needed. Introduced in 2013 for simplicity.

Which Method to Choose?

  • If your office is small (<200 sq ft) and home expenses are high → Actual usually wins
  • If your office is exactly 300 sq ft and home is modest → Simplified caps at same $1,500
  • If you don't want to track home expenses → Simplified, always
  • If you own (not rent) and want depreciation → Actual, but watch recapture on home sale

Depreciation Warning

If you use actual method and claim depreciation, you'll owe "depreciation recapture tax" when you sell your home (even if you exclude the gain). Many homeowners skip depreciation for this reason.
