Business utilities are the recurring services a company pays to keep its workspace running: electricity, natural gas, water and sewer, internet, phone, and waste collection. They show up as operating expenses on your books, and under Section 162 of the Internal Revenue Code they are generally deductible as ordinary and necessary business expenses.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses What you actually pay, and whether you or your landlord writes the check, depends on your lease, your industry, and whether you operate from a commercial space or your home.
What Counts as a Business Utility
The category covers the services a workspace can’t function without. Electricity and gas power lighting, computers, refrigeration, manufacturing equipment, and climate control. Water and sewer handle restrooms, kitchens, fire suppression, and landscaping. Internet and phone carry payments, communications, and cloud applications. Waste collection removes trash and recyclables on a scheduled route. Anything else you might loosely call a “utility bill” that isn’t one of these tends to fall outside the category as the tax code and most leases use it.
Electricity and Gas Costs Look Different for Businesses
Commercial electricity bills are not just bigger residential bills. Along with a per-kilowatt-hour charge for the energy you actually consume, most commercial accounts carry a demand charge. Your provider measures the highest amount of power your building draws during any 15-minute window in the billing cycle, and that peak sets the demand charge for the month. A restaurant that fires up every oven, fryer, and cooler at 5 p.m. will see a higher demand charge than one that staggers equipment startup. Managing that peak is one of the easiest ways to cut an electric bill without reducing total consumption.
Natural gas billing is simpler, typically metered in therms or cubic feet. Businesses that rely on gas for heating, cooking, or industrial processes see seasonal swings, with winter months driving the largest bills.
Water, Sewer, and Waste Pickup
Water is metered by volume, usually in gallons or hundred-cubic-foot increments. Sewer charges often ride alongside the water bill, calculated as a percentage of metered water use on the assumption that most water entering the building eventually leaves through the drain. High-water businesses like laundromats, breweries, and car washes should ask whether their provider offers tiered rates or a separate irrigation meter, which can shave sewer charges off water that never reaches the sewer.
Commercial waste collection is priced by container size and pickup frequency. A small retail shop with one bin emptied weekly pays far less than a restaurant filling a large dumpster five days a week. Costs vary widely by region, but most businesses should plan to budget several hundred dollars a month for standard service.
Internet and Phone Service
Commercial internet plans differ from residential service in ways that matter for how you work. Business contracts typically offer symmetrical upload and download speeds, which counts if you regularly move large files, host video calls, or run a server on site. They also include service level agreements guaranteeing a specific uptime percentage, with credits or penalties if the provider falls short.
Where an outage means lost revenue, a secondary connection through a different provider or technology type acts as a safety net. A common setup pairs a primary fiber connection with a cellular backup on LTE or 5G. Dual-WAN or SD-WAN routers switch automatically when the primary link drops, keeping point-of-sale systems and cloud applications running.
Landline service and business cellular plans round out this category. Many companies have shifted to internet-based voice systems, but the principle is the same: phone service is a utility cost tied to daily operations.
Hazardous and Universal Waste Are Not Covered by Trash Pickup
Standard waste hauling handles ordinary trash and recycling. It does not handle hazardous waste, and treating it as if it does creates serious legal exposure. The Resource Conservation and Recovery Act sets federal rules for how hazardous materials must be tracked, stored, transported, and destroyed, and it requires generators to secure a tracking number, label waste properly, and send it to a licensed treatment, storage, or disposal facility.2Cornell Law School. Resource Conservation and Recovery Act (RCRA)3eCFR. 40 CFR Part 261 – Identification and Listing of Hazardous Waste4Office of the Law Revision Counsel. 42 US Code 6928 – Federal Enforcement5eCFR. 40 CFR 19.4 – Statutory Civil Monetary Penalties
Even businesses that don’t consider themselves hazardous waste generators often handle items federal regulations classify as “universal waste”: batteries, fluorescent lamps and bulbs, certain pesticides, and mercury-containing equipment. These cannot go in the regular dumpster. Batteries showing leakage must be placed in closed, structurally sound containers. Fluorescent lamps must be stored in packaging designed to prevent breakage, and any broken lamp must be cleaned up immediately and sealed in a container.6eCFR. Part 273 – Standards for Universal Waste Management
Who Pays: Utilities Under Different Commercial Leases
If you rent your space, the lease type decides whose desk the utility bills land on. Sort this out before signing, because the difference can add thousands of dollars a year to your real occupancy cost.
Under a full-service gross lease, the landlord pays all operating expenses, including utilities. You pay one flat rent and electricity, water, gas, and trash are baked in. Simple, but you have less incentive to conserve because you never see the bills.
Under a triple net lease, you pay base rent plus your share of property taxes, insurance, and operating costs. Utilities fall to the tenant. You either set up accounts directly with the provider or reimburse the landlord based on metered usage.
Under a modified gross lease, landlord and tenant split operating expenses in some negotiated combination. Utilities for your individual space typically go to you; shared building costs like common-area lighting or HVAC may be built into rent.
In multi-tenant buildings where units aren’t separately metered, landlords sometimes use submeters to allocate utility costs. State laws generally require that tenants pay no more than the actual per-unit cost the landlord pays and prohibit landlords from profiting on the pass-through. If your lease uses submetered billing, you’re entitled to enough information to verify the charges.
Deducting Business Utilities on Your Taxes
Electricity, gas, water, sewer, internet, phone, and waste collection paid for a business location all qualify as ordinary and necessary business expenses under Section 162, and you deduct the full amount on your business return for the year you pay them.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses
Businesses that invest in energy-efficient building systems can also claim a deduction under Section 179D. Qualifying upgrades to interior lighting, HVAC, hot water systems, or the building envelope that achieve at least 25% energy savings are eligible. The deduction ranges from $0.58 to $5.81 per square foot depending on the level of energy savings and whether the project meets prevailing wage and apprenticeship requirements. There’s a hard deadline: under the One Big Beautiful Bill Act enacted in July 2025, Section 179D does not apply to property where construction begins after June 30, 2026.7Department of Energy. 179D Energy Efficient Commercial Buildings Tax Deduction
Utilities When You Work From Home
When you run a business from your home, a portion of your residential utility bills becomes deductible. The IRS allows you to deduct the business percentage of expenses like electricity, gas, trash removal, and cleaning services.8Internal Revenue Service. Publication 587 (2025), Business Use of Your Home Two rules control whether and how much you can claim.
Exclusive and Regular Use
You must use a specific area of your home exclusively and regularly for business. The spare bedroom you converted into an office cannot double as a guest room on weekends. The space doesn’t need a permanent wall, but it does need to be identifiable and used only for work. Occasional or incidental use doesn’t count.8Internal Revenue Service. Publication 587 (2025), Business Use of Your Home Exceptions exist for inventory storage and daycare facilities, but most home-based owners have to satisfy both tests.
Regular Method vs. Simplified Method
Once you qualify, you have two ways to calculate the deduction. Under the regular method, you measure the square footage of your office and divide by the total square footage of your home. That percentage applies to your utility bills. If your office is 15% of your home, you deduct 15% of electricity, gas, water, and internet costs. You have to track actual expenses and keep records of every bill.8Internal Revenue Service. Publication 587 (2025), Business Use of Your Home
Under the simplified method, the IRS gives you a flat $5 per square foot of home office space, up to 300 square feet. That caps the deduction at $1,500 a year. You skip the recordkeeping, but you also cannot deduct actual utility costs separately.9Internal Revenue Service. Simplified Option for Home Office Deduction
The regular method usually produces a larger deduction if your utility costs are high or your office is larger than 300 square feet. The simplified method works well for small home offices where the recordkeeping isn’t worth the marginal benefit. Homeowners’ association fees, if you pay them, can also be partially deducted under the regular method using the same business-use percentage. A dedicated business phone or internet line used 100% for work can be deducted in full, without a percentage calculation.
Opening a Commercial Utility Account
Setting up commercial service takes more time and paperwork than residential signup. Providers typically want your business registration documents, a federal tax ID number, and proof of your right to occupy the property, whether a lease or a deed.
Most commercial providers require a security deposit before activating service. The amount is usually based on an estimate of your first few months of usage, and providers often hold it for two to three years before returning it, assuming you keep a good payment record. Businesses without established credit may face larger deposits.
For new construction or major renovations, connecting to the electric grid involves several phases: gathering technical details about your power needs, engineering design, permitting, and finally construction and installation. The whole process can take several months. Water and gas connections follow a similar sequence. Coordinating all three utilities early in a construction project prevents delays at the end, when you’re ready to open the doors.
