What utilities are deductible
Any utility expense paid by the landlord for a rental property is a deductible operating expense on Schedule E: electricity, natural gas, water, sewer, trash collection, and internet or cable if included in the lease. The deduction is in the year you pay the bill (cash method).
The most common scenarios where the landlord pays utilities: multi-family buildings where utilities are shared or centrally metered; short-term rentals (Airbnb/VRBO) where utilities are included in the nightly rate; rent-inclusive arrangements where utilities are bundled in one monthly payment; and commercial properties with certain lease structures.
Utility bills are easily documented — keep monthly statements or include them in a per-property expense log. If you pay online, bank records plus the utility account statements are sufficient.
Tenant reimbursements: income and deduction net to zero
If your lease requires tenants to reimburse you for utilities, those reimbursements are rental income when received. You then deduct the actual utility costs you paid. Net taxable income is zero on this round-trip — the reimbursement income equals the expense deduction.
Do not skip reporting the reimbursements as income just because the net effect is zero. Your Schedule E should show both the income and the expense. Under-reporting income (even when offset by an equal deduction) creates a discrepancy with any 1099 forms the tenant may issue and increases audit risk.
Allocation for mixed personal and rental use
If you use a property for both rental and personal use (vacation home), utility expenses must be allocated. The rental portion is deductible; the personal portion is not.
Allocation method: rental days ÷ total days of use (not vacant days). If you rented 90 days and personally used 30 days, your rental-use percentage is 75%, and you deduct 75% of utilities.
For a building where you live in one unit and rent another: allocate utilities by unit. If separately metered, each unit's utility bill is attributable to that unit directly. If not separately metered, allocate by square footage or unit count.
Utilities during vacancy and before the property is placed in service
Once a property is placed in service — available and being held out for rent — utility costs remain deductible even during a vacancy between tenants. A vacant rental is still an operating rental as long as you are genuinely trying to rent it, so the power and water bills you pay to keep it show-ready and maintained continue to be Schedule E expenses.
The line is different before the property is placed in service. Utilities paid while you are still renovating a property that has never been available for rent are generally treated as startup or pre-operational costs, capitalized rather than deducted as current operating expenses. The moment the unit is ready and advertised, the meter starts running on deductible operating costs.
Practical takeaway: keep the utilities on and document your rental-marketing efforts during vacancies so the ongoing deductions are clearly tied to an active rental activity, not a property held off the market or under a gut renovation.
RUBS, submetering, and billing tenants for utilities
Larger landlords often recover utility costs through a ratio utility billing system (RUBS) or submeters rather than paying and absorbing them. The tax treatment follows the cash: whatever the tenant pays you toward utilities is rental income when received, and the utility bills you actually pay to the provider are deductible expenses. Both sides belong on Schedule E even though a full pass-through nets close to zero.
Submetering — installing individual meters so each unit's actual usage is billed — does not change the income/expense reporting when the landlord holds the master account and rebills tenants; it just makes the allocation precise. If instead each unit is on its own utility-company account in the tenant's name, the landlord neither reports the payments as income nor deducts them, because they were never the landlord's expense.
One nuance: money a tenant pays you that is labeled a utility charge but is really additional rent (a flat monthly "utility fee" unrelated to actual usage) is simply rental income, and you deduct whatever utilities you in fact pay.
A worked example: a triplex on one water meter
You own a triplex on a single master water and sewer account and pay the bills yourself: $3,600 for the year. The three units are similar in size, so you allocate by unit count — but you occupy one unit as your home. Two-thirds of the property is rental, so $2,400 of the water and sewer cost is deductible on Schedule E and $1,200 (your personal unit) is nondeductible.
Now suppose your leases require each renting tenant to pay a flat $40 per month toward water. That is $960 of rental income for the year ($40 × 2 units × 12 months), reported on Schedule E as rents or as other income, and you still deduct the $2,400 of rental-share water cost. The net effect is $960 of income against $2,400 of expense, leaving a $1,440 net deduction for the rental portion — plus your own $1,200 share remains a nondeductible personal cost.
Common mistakes with rental utility deductions
Omitting reimbursements from income. Netting utilities silently — deducting the bill but not reporting the tenant's reimbursement — understates gross income and creates a mismatch if the tenant or a platform reports the payment. Show both the income and the expense.
Deducting a personal share. In a duplex or house hack, only the rental-use portion of a shared meter is deductible. Allocate by square footage or unit count and keep the method consistent year to year.
Deducting tenant-paid utilities. If the account is in the tenant's name and they pay the provider directly, it is not your expense and cannot be deducted.
Capitalizing utility infrastructure as an operating cost. The monthly bill is an expense, but installing a new service line, a submetering system, or upgrading the electrical service is a capital improvement that is depreciated, not deducted in full in the year paid.
Short-term rentals: utilities as a core operating cost
For short-term rentals (Airbnb, VRBO, and similar), the landlord almost always pays every utility because guests stay for days, not months. Electricity, gas, water, sewer, trash, internet, and streaming services bundled into the nightly rate are all deductible operating costs of the rental activity. On a heavily used short-term rental these bills are a large line item, so track them carefully.
Two wrinkles apply more often to short-term rentals than to long-term ones. First, if you also use the property personally (a beach house you rent part of the year), you must allocate utilities between rental and personal days, and the vacation-home rules under Section 280A can limit deductions when personal use is significant. Second, short-term rentals reported on Schedule C (when substantial services are provided) versus Schedule E follow the same utility-deduction logic, but the surrounding rules differ — confirm which schedule your activity belongs on.
Where a property is a dedicated short-term rental with no personal use, 100% of utilities are deductible with no allocation, the same as any other full-time rental.
Which schedule and line: reporting utilities correctly
For a typical rental, utilities are reported on Schedule E, line 17 (Utilities). Group electricity, gas, water, sewer, and trash there. Internet and cable provided to tenants can go on the utilities line or another appropriate expense line, as long as you are consistent from year to year.
Keep the reporting clean: report gross rents and any utility reimbursements as income, and the full utility bills you paid as expenses, rather than reporting a netted figure. Consistent, line-by-line reporting makes your return easier to defend and avoids the mismatches that draw questions — especially when a tenant, property manager, or platform issues a Form 1099 that reflects gross amounts.
If you own multiple properties, track utilities per property. Schedule E has separate columns for each property, and lumping utilities across properties makes it impossible to show the correct per-property net income the form requires.
Frequently asked questions
Can I deduct utilities I pay on a tenant's behalf?
Yes. Utilities you pay for a rental property are operating expenses deductible on Schedule E, whether or not the lease calls for tenants to reimburse them.
What if tenants pay utilities directly to the utility company?
If tenants pay utilities directly, those costs are not your expense and you cannot deduct them. You also don't report them as income.
How do I deduct utilities for a duplex where I live in one unit?
Deduct only the rented unit's utilities. If utilities are on one meter, allocate by square footage or unit count between the two units.
Can I deduct utilities while the property is vacant between tenants?
Yes, as long as the property is placed in service and genuinely held out for rent. Utilities paid during a normal vacancy remain deductible operating expenses. Utilities paid before a property is ever available for rent — during an initial renovation — are startup costs, not current deductions.
Is internet or Wi-Fi I provide to tenants deductible?
Yes. If your lease includes internet or cable and you pay for it, it is a deductible utility-type operating expense on Schedule E. For a mixed-use property, allocate the cost to the rental-use portion.
If I charge tenants a flat monthly utility fee, is it taxable?
Yes. A flat utility fee or a RUBS charge you collect is rental income when received. You separately deduct the utilities you actually pay to the provider. Report both — do not net them silently.
Which line of Schedule E do rental utilities go on?
Utilities are reported on Schedule E, line 17. Group electricity, gas, water, sewer, and trash there, and track them separately for each property using the form's per-property columns. Report gross rents and any utility reimbursements as income rather than netting them against the expense.
Are utilities on a short-term rental deductible?
Yes. On an Airbnb or VRBO the landlord typically pays every utility, and those costs — electricity, gas, water, sewer, trash, and internet — are deductible operating expenses. If you also use the property personally, allocate utilities between rental and personal days under the vacation-home rules; a dedicated short-term rental deducts 100%.
