Where to pay your TEP bill
Tucson Electric Power gives you four main ways to pay: online through their website, by phone, by mail, or in person at a payment location. The fastest and most convenient route for most people is online at tep.com, where you can pay immediately using a bank account or debit card with no fee.
If you prefer to speak with someone, you can call TEP's payment line at 1-877-832-2383 to pay by phone using a debit card or bank account. Phone payments go through right away. You can also mail a check or money order to the address printed on your bill — allow 7 to 10 business days for mail to arrive and post.
For in-person payment, TEP has payment drop boxes and customer service locations in Tucson. Check tep.com for the nearest location and its hours, as these vary by site. Some locations accept cash, checks, and card payments, while others may be drop-box only.
Key Takeaways
- Online payment at tep.com is free, immediate, and available 24/7 — the fastest way to pay if you have your account number and a debit card or bank account.
- Phone payment through 1-877-832-2383 also has no fee and processes the same day, but requires speaking with a representative during business hours.
- Mail payments take 7 to 10 business days to reach TEP and post to your account, so send them well before your due date to avoid a late fee.
- TEP does not charge a fee for any standard payment method — avoid third-party payment websites that advertise convenience fees, as those are not TEP's official channels.
Setting up automatic payments
If you want to stop thinking about your bill each month, TEP offers automatic payment through their website. You can set it to pay your full balance on a date you choose each month, or you can pay a fixed amount if your bill varies.
To enroll, log into your account at tep.com, go to the billing section, and select the automatic payment option. You will need a bank account or debit card on file. You can change or cancel automatic payments anytime through your account, and TEP will send you a confirmation email each time a payment is scheduled.
Automatic payment does not lock you into a contract — you remain free to adjust your payment method or amount whenever you need to.
What to do if you cannot pay on time
If you know your payment will be late, contact TEP before your due date. Calling 1-877-832-2383 or visiting tep.com to message your account representative can sometimes buy you a few extra days without a late fee, depending on your account history and the reason for the delay.
TEP also offers a budget billing plan that spreads your annual costs into equal monthly payments, which can make it easier to budget if your bill swings between seasons. You can ask about this when you call, or look for it in your account settings online.
If you are struggling with the cost of electricity, TEP runs a Low Income Assistance Program that may help with bill payment. Contact TEP directly or reach out to Community Services for the Homeless, which administers the program locally, to learn whether you may be may be able to access based on your household income.
Reading your TEP bill before you pay
Before you pay, take 30 seconds to check three things on your bill: the account number (to make sure it is yours), the amount due, and the due date. Your account number appears at the top of the bill and is what you will need if you pay online or by phone.
The amount due is the total you owe for that billing period. If you have a balance from a previous month, it will be added to your current charges. The due date is printed clearly — paying after this date triggers a late fee, usually around 1.5% of your balance.
If the bill looks wrong — if your usage spiked suddenly or the charges do not match what you expected — contact TEP before you pay. They can explain the charges or investigate a possible meter problem. Paying first and disputing later is slower.
Avoiding payment scams and fraud
TEP will never call you asking for payment information or threatening to shut off your power immediately. If someone calls claiming to be from TEP and demanding payment right now, hang up and call TEP directly at 1-877-832-2383 to verify whether you actually owe money.
Pay only through the official channels listed above: tep.com, the phone number above, mail to the address on your bill, or an official TEP payment location. Do not use third-party payment apps or websites that claim to pay TEP bills unless you initiated the search yourself and confirmed the site is legitimate — scammers create fake payment sites that look like the real thing.
If you receive a bill that looks suspicious or an email asking you to click a link and log in, forward it to TEP's fraud team or call them directly. Never click a link in an unsolicited email, even if it looks official.
Paying a past-due bill
If your bill is already past due, you can still pay online, by phone, or by mail using the same methods above. A late fee will have been added to your balance, but paying now stops additional fees from accumulating.
If your account is significantly past due, TEP may have scheduled a service disconnection. Paying the full past-due amount, including late fees, usually stops the disconnection, but you should call 1-877-832-2383 to confirm your account status and the exact amount needed to prevent shutoff. Timing matters — once a disconnection notice is issued, you have a limited window to pay before service is cut.
If you cannot pay the full past-due amount at once, ask TEP about a payment arrangement. They may allow you to split the past-due balance into smaller payments over a few weeks while you continue paying current bills on time.
Getting a receipt and keeping records
When you pay online, TEP sends you a confirmation email immediately with your payment details and confirmation number. Keep this email as your receipt. If you pay by phone, ask for a confirmation number before you hang up and write it down.
For mail payments, keep a copy of the check or money order and the envelope you sent it in. If you pay in person, ask for a written receipt on the spot.
These records matter if there is ever a dispute about whether a payment posted to your account. If you pay and the amount does not show up within a few business days, you will have proof of when and how much you sent.
Frequently Asked Questions
Is there a fee to pay my TEP bill online?
No. TEP does not charge a fee for online payment through tep.com, phone payment, mail, or in-person payment at an official location. If a website claims to be TEP but charges a convenience fee, it is not an official TEP channel.
Can I pay my bill with a credit card?
TEP accepts debit cards and bank account payments online and by phone, but not credit cards directly. Some credit card companies allow you to set up a bill payment from your card to TEP's mailing address, but that goes through your bank, not TEP, and may take longer.
What happens if I pay after the due date?
A late fee of approximately 1.5% of your balance is added to your next bill. If you are more than 30 days late, TEP may issue a disconnection notice. Paying as soon as you realize you are late stops additional fees from piling up.
How long does it take for an online payment to show up on my account?
Online payments through tep.com usually post within one business day. You will see a confirmation immediately after you submit the payment, and the amount will appear in your account balance shortly after.
Can I change my payment due date?
TEP typically assigns your due date based on when your meter is read, but you can contact them at 1-877-832-2383 to ask about changing it. If you set up automatic payments, you choose the date each month, so you have full control over when money leaves your account.
