Home office deduction allows self-employed individuals and qualifying employees to deduct expenses for the business use of their home.

Deduction = Office Area (sq ft) x $5 per sq ft
- Maximum: 300 sq ft ($1,500 max deduction)
- No depreciation calculation needed
- Cannot deduct actual expenses separately
Metric note: Convert m² to sq ft by multiplying by 10.764.
Deduction = Office Area (m²) x 10.764 x $5
Regular Method:
Business Use % = Office Area / Total Home Area x 100
Deduction = Total Home Expenses x Business Use %
Deductible home expenses (regular method):
- Mortgage interest or rent
