If you work from home, you may be able to deduct a portion of your home expenses against your business income.
How it works:
Calculate the percentage of your home used exclusively for business.
(Most common method: business area ÷ total home area)
Apply that percentage to your eligible home expenses:
— Rent (if renting) or mortgage interest (not principal)
— Utilities
— Internet (business portion)
— Home insurance (business portion)
— Property tax (business portion)
— Repairs and maintenance
Important rules:
— The space must be used regularly and exclusively for business
— You cannot create or increase a business loss with home office expenses (for employees — business owners have different rules)
— Keep records of your home costs and the calculation method
The home office deduction is often underused — and sometimes overclaimed. Get the calculation right once, and apply it consistently.
