Short answer
Depends. Utilities may be tax deductible when they’re paid for business premises, or when you allocate a portion of utilities to a qualifying home office (subject to current rules).
Personal utilities are not deductible by themselves.
Who this typically applies to
- Business owners paying utilities for a commercial space (office, shop, studio, warehouse)
- Self-employed / freelancers with a qualifying home office who allocate utilities
- Contractors running a business from home and claiming a home office share
Employees working from home may be limited depending on current rules and reimbursements.
When utilities are more likely deductible
- Utilities paid for a separate business location used for business operations
- You have a qualifying home office and allocate a reasonable portion (often by square footage)
- The utility costs are ordinary and necessary for operating the business
- You keep bills, payment proof, and documentation supporting the allocation method
When utilities are not deductible (or risky)
- Utilities for personal living expenses (no business allocation)
- Claiming a share without a clearly defined business space
- Using the “home office” area heavily for personal purposes (mixed-use without support)
- Double-counting utilities that were reimbursed by an employer or client
Example: allocating utilities for a home office
If you have a qualifying home office, you may allocate utilities using a reasonable method (often based on square footage).
Example
- Monthly utilities (electric/gas/water): $300
- Home size: 1,200 sq ft
- Dedicated office: 120 sq ft (10%)
- Potential utilities share: $30/month (subject to current rules)
Keep your method consistent and document the business use of the space.
What records to keep
- Utility bills (electric, gas, water, etc.) and proof of payment
- Home office documentation (photos/notes, square footage calculation, business-use explanation)
- A brief note explaining your allocation method (and why it’s reasonable)
