Where to pay your Tucson utility bill
Tucson Water and Tucson Electric Power (TEP) are both city-owned utilities, and both let you pay online through the City of Tucson's website. You can also pay by phone, mail, or in person at a payment center. The fastest route is the online portal at tucsonaz.gov, where you can set up a one-time payment or enroll in automatic monthly payments.
If you receive bills from both utilities — water and electric — you'll log in once and see both accounts in the same place. This matters because many households in Tucson use both services, and paying them together saves time.
Key Takeaways
- Tucson Water and TEP both use the same online payment portal at tucsonaz.gov, accessible 24 hours a day.
- You can pay with a debit card, credit card, or bank account, though credit card payments may include a processing fee.
- Setting up automatic monthly payments prevents late fees and takes about five minutes to complete.
- If you cannot pay your full bill, contact the utility directly about budget billing or payment plans before your account falls behind.
- Payment centers and phone lines are available if you prefer not to pay online, though online is fastest.
Logging in and making a one-time payment online
Go to tucsonaz.gov and look for the "Pay My Bill" or "Utility Payments" link on the homepage. You'll need your account number, which appears on your paper bill or in any email the utility sends you. If you don't have your account number, you can search by your service address instead.
Once you're logged in, you'll see your current balance, due date, and payment history. Select the amount you want to pay — you can pay the full balance, a partial amount, or a specific dollar figure. Choose your payment method: debit card, credit card, or bank account. Debit and bank account payments are free; credit card payments typically include a small processing fee (usually 2 to 3 percent).
After you submit payment, you'll receive a confirmation number on screen and by email. Keep this number for your records. The payment usually posts to your account within one business day for bank transfers and the same day for card payments.
Setting up automatic monthly payments
Automatic payments mean your bill gets paid on the same day each month without you having to log in. This is the easiest way to avoid late fees and service disconnection. From the same payment portal, look for "Enroll in Auto Pay" or "Set Up Recurring Payment."
You'll choose a payment date (usually between the 1st and the 28th of the month), your payment method, and the amount. You can set it to pay your full bill each month or a fixed dollar amount if you're on a payment plan. You can change or cancel automatic payments anytime through the same portal.
Paying by phone or mail if you don't use the website
If you prefer not to pay online, Tucson Water and TEP both accept phone payments. Call the utility directly — the number is on your bill. Have your account number and payment method ready. Phone payments are processed the same day and cost the same as online payments (free for bank accounts, a fee for credit cards).
You can also mail a check or money order to the address on your bill. Include your account number on the check. Mail payments take 7 to 10 days to reach the utility and post to your account, so mail early if your due date is coming up.
Payment centers are open during business hours at several locations around Tucson. You can pay in person with cash, check, or card. The utility's website lists current payment center addresses and hours.
What to do if you can't pay your full bill
If you're short on money before your due date, contact Tucson Water or TEP before your account becomes past due. Both utilities offer budget billing, which spreads your annual costs into equal monthly payments so bills don't spike in summer or winter. This doesn't reduce what you owe, but it makes the bill more predictable.
Both utilities also offer payment plans for customers who have fallen behind. You'll work out a schedule to pay your arrears (what you already owe) plus your current bill over several months. The utility won't disconnect your service while you're on an active payment plan, as long as you make the agreed payments on time.
If you're struggling with energy costs because of income, ask about low-income programs. Tucson Water and TEP both have programs that may reduce your bill or help you catch up on arrears. The utility can tell you what you need to bring to apply.
Understanding your bill and due date
Your Tucson utility bill shows your current charges, any balance from the previous month, and your due date. The due date is usually 20 days after the bill is mailed. If you pay after the due date, a late fee is added to your next bill.
Your bill also shows your usage for the month — kilowatt-hours for electric, gallons for water — and the rate you're charged per unit. Rates vary by season for electric (summer rates are higher) and by how much water you use (higher usage costs more per gallon). Understanding these details helps you spot billing errors and see where you can cut costs.
Setting up account alerts and managing your account online
Once you're logged into the portal, you can set up email or text alerts for when your bill is ready, when it's due, and when a payment is processed. These alerts help you stay on top of due dates and catch problems early.
You can also view your payment history, see past bills, and update your contact information in the same portal. If you move or change your phone number, update it there so the utility can reach you if there's a problem with your account.
Frequently Asked Questions
What if I don't have an account number?
You can search for your account using your service address instead of your account number. The portal will pull up all accounts at that address. If you still can't find it, call the utility directly — they can look it up by your name and address.
Can I pay someone else's bill online?
You can pay another person's bill if you have their account number and know their service address. However, you won't see their account details or payment history — you'll only be able to make a payment. If you need ongoing access to manage someone else's account, they'll need to add you as an authorized user through the utility directly.
What happens if I pay late?
A late fee is added to your next bill if you pay after the due date. If your account stays past due for 30 days, the utility may send a disconnection notice. If you receive a notice, contact the utility immediately — they may pause the disconnection if you're working on a payment plan or have a hardship.
Is there a fee for paying with a credit card?
Yes, credit card payments usually include a processing fee of 2 to 3 percent of the payment amount. Debit card and bank account payments are free. If the fee is a concern, use a debit card or bank account instead.
Can I change my automatic payment date or amount?
Yes. Log back into the portal, find your automatic payment setup, and edit the date or amount. Changes take effect on your next scheduled payment. You can also cancel automatic payments anytime through the same portal.
