Log in to your TXU account to pay your bill
Go to txu.com and click the login button in the top right corner. Enter the email address or account number associated with your TXU account, then your password. If you have not created an online account yet, you will need to set one up first — click "Create Account" and follow the prompts to link your account using your service address and account number (both appear on your paper bill).
Once you are logged in, your dashboard shows your current balance, due date, and usage. To pay, click "Pay My Bill" or "Make a Payment" — the exact wording varies slightly depending on whether you have electric service, gas service, or both. You can pay the full amount due or a partial payment.
TXU accepts payment by bank account (ACH transfer), debit card, or credit card. Bank transfers usually process the same day if submitted before 5 p.m. Central Time on a business day. Card payments process immediately but may carry a small fee depending on your card type.
Key Takeaways
- Create your TXU online account at txu.com using your service address and account number from your bill if you do not already have one.
- Log in with your email address or account number and password to see your balance and due date.
- Pay by bank transfer (usually same-day), debit card, or credit card through the "Pay My Bill" button on your dashboard.
- Set up autopay in your account settings to have your bill paid automatically each month on a date you choose.
- If you forget your password, use the "Forgot Password" link on the login page to reset it by email.
Set up automatic payments to avoid late fees
Autopay removes the step of logging in each month. In your account settings, select "Autopay" or "Automatic Payments" and choose your payment method (bank account, debit card, or credit card). You can pick the date the payment should process each month — many customers choose a few days after payday to ensure funds are available.
You can change or cancel autopay anytime through your account settings. TXU will send you a confirmation email when autopay is set up and another email before each payment is processed, so you always know when money will leave your account.
What to do if you cannot remember your login details
Click "Forgot Password" on the TXU login page. Enter your email address or account number, and TXU will send a password reset link to the email on file. Follow the link and create a new password. The reset link expires after a set time, so complete the process soon after requesting it.
If you do not have access to the email address on your account, call TXU customer service at 1-888-TXU-CUST (1-888-898-2878). Have your account number and service address ready. A representative can verify your identity and help you regain access or update your email address.
Pay by phone or mail if you prefer not to use the website
You can pay over the phone by calling 1-888-898-2878. Have your account number ready and tell the representative your preferred payment method. Phone payments by bank account or debit card process the same day if called before 5 p.m. Central Time on a business day.
To pay by mail, write a check or money order payable to TXU Energy and include your account number on the check. Mail it to the address shown on your bill — this address changes based on your location within TXU's service area. Mail payments typically take 5 to 7 business days to post to your account, so send payment at least a week before your due date to avoid a late fee.
Understand your bill due date and late payment fees
Your due date appears on your bill and in your online account. Payment is considered on time if it is received by 5 p.m. Central Time on the due date. If you pay after that time, TXU may charge a late fee — the amount varies but is shown in your account terms.
If you are struggling to pay your full bill, contact TXU before the due date. TXU offers budget billing (which spreads your annual costs into equal monthly payments) and may have hardship programs depending on your location and circumstances. Calling ahead is better than paying late, because late payments can affect your credit and lead to service disconnection if bills remain unpaid.
Troubleshoot common login and payment problems
Account locked after multiple failed login attempts: TXU temporarily locks your account after several wrong password entries to protect your information. Wait 30 minutes and try again, or use "Forgot Password" to reset it immediately.
Payment shows as pending but not yet posted: Bank transfers and card payments can take 1 to 3 business days to appear on your account, depending on your bank and the payment method. Check your account again in a few days. If the payment still does not show after a week, contact TXU with your confirmation number.
Website is slow or will not load: Try clearing your browser's cache and cookies, then log in again. If the site remains slow, try a different browser or device. TXU occasionally performs maintenance during early morning hours — if you cannot access the site, try again later.
You see a charge you did not authorize: Log in and check your payment history to see the date and amount. If the charge is unfamiliar, call TXU immediately at 1-888-898-2878 with the transaction date. Do not ignore it — TXU can investigate and reverse unauthorized charges.
Frequently Asked Questions
Can I pay my TXU bill without creating an online account?
Yes. You can pay by phone at 1-888-898-2878, by mail using the payment coupon on your bill, or in person at a TXU payment location (check txu.com for locations near you). Creating an online account is optional but saves time if you pay regularly.
Does TXU charge a fee to pay my bill online?
Bank account (ACH) payments are free. Credit and debit card payments may carry a small fee — TXU shows the exact amount before you confirm payment. Paying by phone or mail is also free.
What happens if my payment fails?
TXU sends you an email notification if a payment fails. Log back in and try again with a different payment method, or call 1-888-898-2878 for help. A failed payment does not count as on-time, so resubmit as soon as possible to avoid late fees.
Can I see my payment history online?
Yes. Log in to your account and look for "Payment History" or "Transaction History" in the dashboard or account settings. You can see past payments, their dates, amounts, and status (posted, pending, or failed).
How do I change my due date?
Log in and look for "Billing" or "Account Settings." Many customers can change their due date directly in the online portal. If the option is not available, call 1-888-898-2878 and a representative can adjust it for you.
