An “ACT City of Mesa” charge on your bank or card statement is a payment to the City of Mesa, Arizona, almost always for municipal utility service. Mesa runs its own electric, natural gas, water, wastewater, and solid waste utilities, and it bills them together, so a single line on your statement can cover several services at once. The same descriptor can also appear for other city payments, such as a building permit or a municipal court fine.
Why the City Itself Is Billing You
Most Arizona cities leave utilities to private companies. Mesa doesn’t. The city provides electricity to roughly 19,000 homes and businesses in an approximately 5.5-square-mile area that includes downtown (Salt River Project serves the rest). It also delivers natural gas across a 90-square-mile territory inside city limits, with service extending into parts of the Salt River Pima–Maricopa Indian Community, Apache Junction, Gilbert, and Chandler, plus a separate 240-square-mile “Magma” territory in Maricopa and Pinal counties. Water, wastewater, and trash collection are provided citywide.
Because so many services come from the same provider, Mesa consolidates them onto one monthly bill. That single payment is what shows up on your statement.
What’s Usually in the Charge
A residential Mesa utility bill combines service charges and usage-based rates for each utility you receive. On the electric side, the city charges a monthly system service charge of $20.50, plus usage rates that shift by season: summer rates (May through October) run roughly $0.053 per kilowatt-hour for the first 1,200 kWh, and winter rates (November through April) start around $0.045 per kWh for the first 800 kWh. An Electric Energy Supply Cost Adjustment Factor is added to cover purchased-power costs, along with proportional taxes and governmental fees.
Water, wastewater, gas, and solid waste each carry their own service charges and tiered usage rates set by city council resolution. After rate increases that took effect in early 2025, a typical residential bill for water, wastewater, and solid waste combined was projected at about $105.81 per month.
If You Paid by Card, Expect a 2.37% Surcharge
When the charge is on a credit or debit card, it usually includes a 2.37 percent processing fee added on top of the bill. Mesa began assessing this fee in March 2018 to cover card transaction costs; a third-party processor collects it, and the money doesn’t go to the city. The surcharge applies to Visa, Mastercard, and Discover. Mesa stopped accepting American Express when the fee was introduced.
To avoid the fee, you can pay from a checking or savings account (ACH/bank draft), or by check, cash, or money order. A debit card doesn’t get you around it.
Other City Payments That Look the Same
Not every City of Mesa charge is a utility bill. The city collects money across many departments, and several of them run through the same payment system:
- Development services fees, including building permits, plan review, and construction inspections. The 2.37 percent card surcharge applies here too.
- Mesa Municipal Court obligations, including fines, restitution, and incarceration fees. A $70 default fee may also be assessed for failure to appear in a civil traffic case or failure to pay a court-ordered amount, though magistrates can waive it in the interest of justice.
- Falcon Field Airport fees, which process through the same system and carry the card surcharge.
- Class registrations, facility rentals, and other service fees from parks, recreation, and other city departments.
How To Verify or Dispute It
Start at home. Check whether anyone in your household has a Mesa utility account or recently paid for a city service such as a permit, a court fine, or a recreation program. Recurring utility autopay is the single most common source of an unexpected charge.
For billing questions, Mesa’s Office of Management and Budget can be reached at 480-644-5799, and the city’s utility portal at mesaaz.gov lets you view account details and payment history. If you confirm the charge is unauthorized, contact your card issuer to open a dispute in the usual way.
