Where to pay your Tucson utility bill
Tucson Electric Power (TEP) and Tucson Water accept payments through several channels, and the fastest route depends on whether you want to pay right now or set up automatic payments. You can pay online at the TEP website without creating an account, pay by phone, mail a check, or drop a payment at a TEP office or authorized payment location.
The TEP website (tep.com) lets you pay a single bill immediately using a debit or credit card, or set up a bank account for automatic monthly withdrawals. Phone payments go through TEP's automated system at 1-877-832-2383, and you'll need your account number and a payment method ready. If you prefer in-person payment, TEP has offices in Tucson where you can pay by cash, check, or card, and some grocery stores and payment centers accept TEP payments as well.
Mailing a check takes longer — typically 7 to 10 business days to reach TEP and post to your account — so use this method only if your bill is not due soon. Write your account number on the check and mail it to the address shown on your bill.
Key Takeaways

- Automatic payments from your bank account eliminate the need to remember due dates and reduce the risk of late fees.
- TEP offices and authorized payment locations accept cash, check, and card payments in person during business hours.

Setting up automatic payments to avoid late fees
Automatic payments remove the guesswork and protect you from missing a due date. TEP calls this Budget Billing with AutoPay, and it withdraws the same amount from your bank account on the same day each month. You set it up on the TEP website or by calling 1-877-832-2383, and you'll need your bank account number and routing number ready.
The amount TEP withdraws is based on your average usage over the past 12 months, so your payment stays roughly the same even as your actual bill fluctuates with the seasons. This makes budgeting easier, but it also means you may owe money or receive a credit when TEP recalculates your average each year. You can cancel AutoPay at any time through your online account or by calling TEP.
If you don't want a fixed payment amount, you can still set up automatic payments for your actual bill each month. TEP will charge whatever you owe on your due date, so your payment changes with your usage. This option also prevents late fees and requires the same setup process.
Understanding your due date and late payment penalties
Your bill due date appears on the front of your bill statement, usually 18 to 21 days after the bill is mailed. If you pay after that date, TEP adds a late payment charge of 1.5% of the unpaid balance. The charge compounds monthly, so a bill that stays unpaid for several months will accumulate significant fees on top of the original amount owed.
If your payment is more than 30 days late, TEP may disconnect your service without further notice. You'll have to pay the full overdue balance plus a reconnection fee to restore power or gas. If you know you can't pay by the due date, contact TEP before the deadline — they have hardship programs and payment plans for customers facing temporary financial difficulty.
TEP's Customer Assistance Program offers extended payment plans and bill discounts for low-income households. You can ask about this program when you call to discuss a late or unpaid bill, and TEP will explain what documents you need to show.
Paying a bill online without an account
You don't need to create a TEP online account to pay a single bill. Go to tep.com, click "Pay My Bill," and enter your account number and the amount you want to pay. You'll be asked for a payment method — debit card, credit card, or bank account — and the payment processes immediately.
Online payments are free when you pay from a bank account, but TEP charges a fee if you use a debit or credit card. The fee varies depending on the card type and is shown before you confirm the payment, so you can decide whether to proceed or use a different method. The payment posts to your account within one business day.
If you don't have your account number handy, you can look it up on tep.com using your service address and phone number. This takes a few extra minutes but avoids a trip to find your bill.
What to do if you can't pay your full bill
If you're short on money before your due date, contact TEP at 1-877-832-2383 and ask about a payment arrangement. TEP can split your bill into smaller payments spread across several weeks or months, and you won't face disconnection as long as you stick to the agreed schedule. You'll need to make the first payment when you set up the arrangement.
TEP also offers the Lifeline Program for customers age 65 or older, disabled, or receiving certain government benefits. This program reduces your monthly bill by a fixed percentage and is separate from the Customer Assistance Program. You can ask about both when you call, and TEP will tell you which one you may be able to use.
If you've already missed a payment and received a disconnection notice, you have until the date on the notice to pay or set up an arrangement. Paying any amount, even partial, before that date can delay disconnection and give you time to arrange a plan with TEP.
Paying in person at TEP offices and authorized locations
TEP has several payment centers across Tucson where you can walk in and pay by cash, check, or card during business hours. The main office is at 220 West 6th Street in downtown Tucson, and there are smaller payment locations in other neighborhoods. Hours vary by location, so check tep.com for the office nearest you and confirm it's open before you go.
Some grocery stores, pharmacies, and check-cashing services in Tucson also accept TEP payments. These authorized payment locations charge a small fee — usually $1 to $3 — on top of your bill amount. The fee goes to the payment location, not to TEP, but it's worth it if you don't have a bank account or prefer to pay in cash.
In-person payments at a TEP office are free and post to your account the same day. Payments at authorized locations may take one business day to post. If your bill is due the next day, pay at a TEP office to make sure it reaches your account in time.
Handling billing disputes and incorrect charges
If your bill looks wrong — an unusually high charge, a duplicate fee, or a charge you don't recognize — contact TEP before you pay. Call 1-877-832-2383 and ask to speak with a billing representative. Have your bill in front of you and be ready to describe the charge that seems incorrect.
TEP will investigate the charge and either correct it or explain why it's accurate. If you disagree with the explanation, you can file a formal dispute. TEP will then freeze the disputed amount while they investigate further, though you still need to pay the rest of your bill to avoid late fees. The investigation usually takes 30 to 45 days.
If TEP made an error, they'll issue a credit to your account. If the charge was correct, you'll owe the disputed amount plus any late fees that accumulated while it was frozen. Disputing a charge doesn't stop disconnection, so keep paying the undisputed portion of your bill on time.
Frequently Asked Questions
Can I pay my TEP bill with a credit card without a fee?
No. TEP charges a fee for credit card payments, but not for debit card payments or bank account transfers. The fee is shown on the payment screen before you confirm, so you can choose a different payment method if you want to avoid it.
What happens if I pay late but before disconnection?
You'll owe a late payment charge of 1.5% of the unpaid balance, but your service will stay on. If you pay after the disconnection date on your notice, TEP will shut off your service and you'll need to pay a reconnection fee to turn it back on.
How do I know if I'm on a payment plan with TEP?
TEP will send you a written agreement when you set up a payment arrangement. Keep this document and follow the payment schedule exactly. If you miss a payment on the plan, contact TEP immediately to avoid disconnection.
Can I change my due date to match my payday?
TEP doesn't let you change your due date, but you can set up automatic payments for any day of the month. Contact TEP at 1-877-832-2383 to choose a payment date that works with your income schedule.
What if I'm on a fixed income and can't afford my bill?
TEP's Lifeline Program and Customer Assistance Program both reduce bills for low-income households. Call 1-877-832-2383 and ask which program you may be able to use. You'll need to provide proof of income and household size.
