Short answer
Yes, for business use. Utilities for a standalone business location are 100% deductible. Utilities for a home-based business are deductible based on your home office square footage percentage. Personal utilities without a business connection are not deductible.
Internet service follows slightly different rules — it uses a separate business-use percentage based on actual usage, not square footage. See the internet deductibility guide for details.

Who this typically applies to
- Small business owners paying utilities for a commercial office, studio, retail space, or workshop
- Freelancers and self-employed individuals with a qualifying home office who allocate a portion of home utilities to business use
- Contractors and tradespeople operating from a home office or business premises
Employees generally cannot deduct unreimbursed utility costs under current tax rules. These deductions apply to Schedule C filers and business returns.
When utilities are tax deductible
- Utilities paid for a standalone business location used exclusively for business — office, studio, workshop, commercial space
- You have a qualifying home office and can allocate a reasonable business-use percentage of home utilities
- The utility costs are ordinary and necessary for operating your business
- You pay for them yourself and are not reimbursed by an employer, client, or landlord
- You keep utility bills and documentation supporting your allocation method
When utilities are not deductible
- Utilities for purely personal living expenses with no business allocation
- Claiming a home office share without a qualifying dedicated workspace that meets the regular and exclusive use test
- Utilities that are reimbursed by an employer, client, or included in your rent
- Using the simplified home office method — utilities are included in the $5/sq ft rate and cannot be deducted separately
Which utilities are tax deductible?
| Utility type | Standalone business | Home office (actual method) | Schedule C line |
|---|---|---|---|
| Electricity | 100% deductible | Business % of annual bill | Line 25 / Form 8829 |
| Natural gas / heating oil | 100% deductible | Business % of annual bill | Line 25 / Form 8829 |
| Water and sewer | 100% deductible | Business % of annual bill | Line 25 / Form 8829 |
| Trash / recycling | 100% deductible | Business % — may qualify as indirect home office expense | Line 25 / Form 8829 |
| Internet service | 100% if business-only line | Separate business-use % based on actual usage — not square footage | Line 25 or Line 18 |
| Phone / landline | 100% if business-only line | Business-use % of shared line | Line 25 |
Simplified method users: If you use the simplified home office method ($5/sq ft), utilities are already included in that rate. You cannot deduct utilities separately on top of the simplified method deduction.
Standalone business premises: Full utility deduction
If you rent or own a business location used exclusively for business — a commercial office, studio, retail shop, warehouse, or workshop — 100% of the utility costs for that property are deductible as ordinary business expenses.
Utilities for standalone business premises
- Electricity, gas, water, and heat for the business location
- Internet and phone service at the business address
- Trash removal and other facility services
Report on Schedule C, Line 25 (Utilities).
If you own the building, utilities are still deductible as business expenses. If the building is also partially personal (e.g., a mixed-use property), allocate based on business-use percentage.
Home office utility allocation: How it works
For home-based businesses using the actual expense method for the home office deduction, utilities are deductible based on your home office business-use percentage.
How to calculate the deductible utility amount
- Step 1: Calculate your business-use percentage: office square footage ÷ total home square footage
- Step 2: Apply that percentage to each utility bill for the year
- Step 3: Report the results on Form 8829 as indirect home office expenses
- Step 4: The total flows to Schedule C, Line 30
Internet is calculated separately using a business-use percentage based on actual usage hours — not the home office square footage percentage. See the internet deductibility guide.
Where do utility expenses go on Schedule C?
| Situation | Where to report |
|---|---|
| Utilities for a standalone business location | Schedule C, Line 25 (Utilities) |
| Home office utilities (actual expense method) | Form 8829 (indirect expenses) → Schedule C, Line 30 |
| Internet — standalone business line | Schedule C, Line 25 (Utilities) |
| Internet — home office portion | Schedule C, Line 25 or Line 18 (separate from home office %) |
| Simplified home office method | Utilities not deducted separately — included in $5/sq ft rate on Line 30 |
Example: Home office utility deduction calculation
Example: Freelance graphic designer with home office
- Home size: 1,200 sq ft | Office: 150 sq ft | Business-use %: 12.5%
- Annual electricity: $1,800 × 12.5% = $225
- Annual gas/heat: $960 × 12.5% = $120
- Annual water: $480 × 12.5% = $60
- Internet (50% business use, separate calculation): $960 × 50% = $480
- Total deductible utilities: $885
Internet uses a 50% business-use estimate based on actual usage — not the 12.5% home office percentage. These are two separate calculations that both appear in the home office deduction, but internet has its own allocation logic. At a 22% tax rate, $885 in utility deductions saves approximately $195 in taxes.
What records to keep
- Annual utility bills or monthly statements for electricity, gas, water, and heat
- Proof of payment (bank statements or card records)
- Home office square footage calculation (office area and total home area)
- A note confirming the space meets the regular and exclusive use requirement
- Internet billing statements kept separately with your business-use percentage note
- Form 8829 from prior years if carrying forward unused home office deductions
