Paying your Intermountain Gas bill online, by phone, or by mail
Intermountain Gas Company serves customers in Idaho and eastern Oregon. You can pay your bill through their website at intmountaingas.com, by phone at 1-800-543-0450, by mail, or in person at an authorized payment location. The method you choose depends on how quickly you need the payment to post and whether you want to set up automatic payments.
Most people pay online because it takes a few minutes and the payment posts within one to two business days. If you pay by phone, a representative will walk you through your account details and payment method. Mail payments take seven to ten business days to reach the company and post to your account, so send them early if you have a due date approaching.
Intermountain Gas does not charge a fee for paying online, by phone, or by mail. Some third-party payment processors may add a fee if you use their service instead of paying directly through the utility, so check before you confirm the transaction.

Paying online through your account
Log into your account on the Intermountain Gas website using your account number and password. If you do not have an online account, you can create one by entering your account number and the zip code associated with your service address. The website will send you a verification code by email or text.
Once you are logged in, select "Pay My Bill" and enter the amount you want to pay. You can pay the full balance, a partial amount, or set up a one-time automatic payment for future bills. The website accepts debit cards, credit cards, and bank account transfers. If you use a credit card, the payment posts immediately but may take an extra day to show on your bill.
After you submit payment, you will receive a confirmation number. Save this number in case you need to dispute the transaction or verify that the payment went through. Intermountain Gas will also send you an email confirmation.
Setting up automatic payments to avoid missed due dates
Automatic payments deduct money from your bank account on a date you choose, usually a few days before your bill is due. This prevents late fees and service disconnection if you forget to pay. You can set up automatic payments through your online account or by calling 1-800-543-0450.
To set up automatic payments online, log into your account, go to "Billing and Payments," and select "Autopay." Choose the bank account or card you want to use, the amount (full bill or a fixed amount), and the payment date. You can change or stop automatic payments at any time through your account settings.
If your bill amount changes month to month because of seasonal heating or cooling use, you can set automatic payments to deduct a fixed amount each month. This helps you budget, though you may owe a balance at the end of the year if your fixed payment is lower than your actual usage.
What happens if you miss a payment or pay late
If your payment does not arrive by the due date shown on your bill, Intermountain Gas will add a late fee to your next bill. The amount of the late fee varies by state and is shown in your service agreement. After a late payment, the company will send you a notice that your account is past due.
If you do not pay within the notice period (usually 10 to 20 days after the notice is sent), Intermountain Gas may disconnect your service. Before disconnection, the company must send you a final notice with a specific date. If you contact them before that date and make a payment or set up a payment plan, they will not disconnect you.
When your service is reconnected after a disconnection, you will owe a reconnection fee in addition to your unpaid balance. This fee varies but is typically between $50 and $150. Reconnection usually takes one to three business days after you pay.
Setting up a payment plan if you cannot pay in full
If you cannot pay your full bill by the due date, call Intermountain Gas at 1-800-543-0450 before your account becomes past due. A representative can discuss a payment plan that spreads your balance over several months. The company is more likely to work with you if you contact them before you miss a payment.
Payment plans typically require you to pay a portion of your current bill each month plus a portion of your past-due balance. The exact terms depend on how much you owe and your payment history. Once you agree to a plan, make sure you understand the payment dates and amounts so you do not miss a scheduled payment, which would end the plan.
If you are struggling with your bill because of a change in income or a medical emergency, ask the representative about any hardship programs or bill assistance resources in your area. Some community organizations and local government agencies offer help with utility bills.
Paying by phone or mail if you do not have internet access
To pay by phone, call 1-800-543-0450 and have your account number and payment method ready. A representative will confirm your account details, the amount you want to pay, and your card or bank account information. The payment posts within one to two business days.
To pay by mail, write a check or money order payable to Intermountain Gas Company and include your account number on the check. Mail it to the address shown on your bill. Do not send cash through the mail. Allow seven to ten business days for the payment to arrive and post to your account.
You can also pay in person at authorized payment locations in your area. Call 1-800-543-0450 to find the nearest location and confirm their hours. In-person payments usually post within one business day.
Understanding your bill and due date
Your Intermountain Gas bill shows your account number, service address, current charges, any past-due balance, and the due date. The due date is usually 20 to 25 days after the bill is mailed. If the due date falls on a weekend or holiday, the payment is considered on time if it arrives by the next business day.
Your bill includes the cost of natural gas used during the billing period, a customer charge (a fixed monthly fee), and any taxes or surcharges. During winter months, your bill may be higher because of increased heating use. Some customers choose budget billing, which spreads your annual costs evenly across all 12 months so your bill stays roughly the same each month.
If you think your bill is incorrect, contact Intermountain Gas within 30 days of receiving it. A representative can review your account and explain the charges. If there is a genuine error, the company will adjust your bill and may issue a credit.
Frequently Asked Questions
Can I pay my Intermountain Gas bill with a credit card online?

What should I do if my payment was rejected?
If your online payment was rejected, check that your card or bank account information is correct and that you have sufficient funds. Try again or call 1-800-543-0450 to pay by phone. If the problem continues, contact your bank to make sure there are no blocks on the transaction.
How long does it take for a mailed check to post?
Mailed payments typically take seven to ten business days to arrive and post to your account. If your due date is approaching, pay online or by phone instead to avoid a late fee. Always mail checks at least two weeks before the due date.
Can I change my due date?
Contact Intermountain Gas at 1-800-543-0450 to request a different due date. The company may be able to move your due date to align with when you receive income or prefer to pay bills. Changes usually take effect on your next billing cycle.
What happens if I overpay my bill?
If you pay more than you owe, the extra amount becomes a credit on your account and will be applied to your next bill. If you want a refund instead, contact Intermountain Gas and they can mail you a check or credit your account with the utility company.
