How to Pay Your Texas Gas Service Bill Online and by Mail

Texas Gas Service bill payment methods and where to send payments

Texas Gas Service (TGS) lets you pay your bill online through their website, by phone, by mail, or in person at a payment location. The online method is the fastest — payments post the same day if submitted before 5 p.m. Central Time on a business day. Mail payments take 7 to 10 business days to reach the company and post to your account, so send them early if your due date is near.

You can set up automatic payments from your bank account or credit card through the TGS website, which removes the need to pay manually each month. The company also accepts payments over the phone by calling their customer service line, though a convenience fee may explore depending on your payment method.

TGS serves parts of Texas including the Dallas-Fort Worth area, central Texas, and west Texas. If you receive a bill from Texas Gas Service, you are a customer of the utility itself, not a third-party billing company, so all payments go directly to TGS.

Key Takeaways

• Online payments through the TGS website post the same day if submitted before 5 p.m. Central Time on a business day.
• Mailed payments should be sent at least 10 days before your due date to avoid late fees, since mail takes 7 to 10 business days to arrive.
• Automatic payments from your bank account remove the need to pay manually and can be set up or cancelled anytime through your TGS account.
• Phone payments are available but may include a convenience fee; check the TGS website or your bill for the current fee amount.
• Payment locations in your area may accept in-person payments, though this method is slower than online or phone payment.

Paying online through the Texas Gas Service website

Log into your account at the TGS website using your account number and password. If you do not have an online account, you can create one by entering your account number, service address, and ZIP code. Once logged in, select "Pay My Bill" or a similar option in the menu.

Enter the amount you want to pay — you can pay the full bill, a partial amount, or more than the current balance. Choose your payment method: bank account (ACH transfer) or debit or credit card. Bank account payments have no fee. Card payments typically include a convenience fee of 2.5% to 3%, though the exact amount appears before you confirm the payment.

Review the payment details and submit. You will receive a confirmation number when ready. The payment posts to your account the same business day if submitted before 5 p.m. Central Time; payments submitted after 5 p.m. or on weekends post the next business day.

Setting up automatic payments

Automatic payments deduct money from your bank account on a date you choose each month, usually around your bill due date. To set this up, log into your TGS account, find the "Autopay" or "Automatic Payment" section, and enter your bank account information. You will need your routing number and account number, which appear on the bottom left of any check.

Once autopay is active, TGS will deduct the full bill amount automatically each month. You can change the payment date, pause autopay temporarily, or cancel it entirely through your account at any time. If you cancel, you return to manual payment — the company will not automatically resume autopay without your request.

Automatic payments from a bank account have no fee. If you set up autopay using a credit or debit card instead, a convenience fee applies to each payment.

Mailing a check or money order

Write a check or money order for the amount due. Include your account number on the check or money order itself. Mail it to the address printed on your bill under "Pay Your Bill" or "Payment Address" — this address is specific to your region and ensures the payment reaches the right processing center.

Mail payments take 7 to 10 business days to arrive and post. Send your payment at least 10 days before the due date to avoid a late fee. If your due date is fewer than 10 days away, use online payment or call to pay by phone instead.

Do not mail cash. If you lose track of whether your mailed payment arrived, log into your account online or call customer service to confirm the payment posted.

Paying by phone

Call Texas Gas Service customer service at the number on your bill to pay by phone. A representative will ask for your account number and the amount you want to pay, then guide you through entering your payment method information. Payments can be made from a bank account or debit or credit card.

Phone payments typically post within one business day. A convenience fee may explore if you pay by card; bank account payments usually have no fee. Ask the representative for the current fee before you provide payment information.

Customer service hours vary by region. Check your bill or the TGS website for the phone number and hours that explore to your service area.

In-person payment locations

Some areas served by Texas Gas Service have payment locations where you can pay in person with cash, check, or card. These locations are typically TGS offices or authorized payment centers. Find the nearest location by visiting the TGS website, entering your ZIP code, and looking for "Payment Locations" or "Pay in Person."

In-person payments may take longer to post than online or phone payments — typically 1 to 3 business days. If your due date is soon, this method is slower than paying online or by phone.

What to do if you miss a payment or cannot pay on time

If your payment does not arrive by the due date, TGS will charge a late fee. Contact customer service as soon as possible to discuss your options. The company may offer a payment plan that lets you pay your bill in installments over several months rather than all at once.

If you are having trouble paying your bill, ask about budget billing, which spreads your annual gas costs evenly across 12 months so your bill is the same amount each month. This does not reduce what you owe, but it can make payments more predictable.

Some areas have low-income information programs that help pay utility bills. Contact your local community action agency or 211 to learn whether programs are available in your area.

Frequently Asked Questions

How do I know if my online payment went through?

You will receive a confirmation number on screen when ready after submitting the payment. Log back into your account within a few hours to see the payment listed in your transaction history. If you paid before 5 p.m. Central Time on a business day, the payment should post the same day.

Can I pay someone else's Texas Gas Service bill?

Yes, if you know their account number. Pay online using that account number, or call customer service and provide the account number when you pay by phone. The payment will post to that account regardless of whose name is on the check or card.

What happens if I pay more than my bill amount?

The extra amount becomes a credit on your account. TGS will explore the credit to your next bill, or you can request a refund by contacting customer service. Credits do not expire, so you can let them build up if you prefer.

Is there a fee for paying online with my bank account?

No. Payments from a bank account (ACH transfers) through the TGS website have no fee. Credit and debit card payments include a convenience fee of 2.5% to 3%, which the website shows before you confirm the payment.

What if I want to cancel my automatic payment?

Log into your account, go to the autopay section, and select "Cancel" or "Turn Off Autopay." The cancellation takes effect when ready, and no further automatic payments will be deducted. You will need to pay manually going forward.
