By clicking “ACCEPT” (or otherwise accessing or using the Software or Services), you indicate that you have read, fully understood, and agree to be bound by the terms of this Agreement. If you do not agree to the terms of this Agreement, you are not granted any rights whatsoever in the InterSearch Tax Solutions, Inc. software (the “Software”), and you may not access or use the Software or any services provided by InterSearch Tax Solutions, Inc. (the “Services”). In this Agreement, “InterSearch Tax Solutions, Inc.”, “TaxExtension.org”, “us”, “we”, and “our” refer to InterSearch Tax Solutions, Inc. d/b/a TaxExtension.org. “You”, “your”, and “user” refer to the person using the Software or Services.
InterSearch Tax Solutions, Inc. grants you a limited, revocable, non-exclusive, non-transferable license to use the Software solely to: (a) prepare an application for an extension of time to file your United States federal tax return on either IRS Form 4868 or IRS Form 7004; and (b) as part of proper registration and payment, electronically file that application with the Internal Revenue Service (“IRS”), including payment to the IRS, via e-file and e-Pay, where available.
TaxExtension.org is an Authorized IRS e-file Provider, which means we have completed the IRS approval process that allows us to electronically transmit certain tax forms to the IRS on behalf of taxpayers. Our participation in IRS e-file does not mean the IRS endorses TaxExtension.org or our Services.
You are not licensed or permitted under this Agreement to do any of the following:
You agree to indemnify and defend InterSearch Tax Solutions, Inc. against any claims or lawsuits, including attorneys’ fees, that arise from or result from your use of the Software on a professional or commercial basis in violation of this Agreement. The term “Software” includes any programs, tools, internet-based services, components, and any updates (for example, maintenance, service information, help content, bug fixes, or maintenance releases, etc.) that we provide or make available to you.
The Software is licensed, not sold. InterSearch Tax Solutions, Inc. reserves all rights not expressly granted to you in this Agreement. The Software is protected by copyright, trade secret, and other intellectual property laws. InterSearch Tax Solutions, Inc. owns title, copyright, and other intellectual property rights in the Software.

By creating a TaxExtension.org account, you consent to receive electronic communications from TaxExtension.org (e.g., SMS or text messaging, telephone, via email, or by posting notices on our Services). These communications may include notices about your account (e.g., authentication, payment authorizations, password changes, and other transactional information) or legal notices and are part of your relationship with us. You agree that any notices, agreements, disclosures, or other communications that we send to you electronically will satisfy any legal communication requirements, including, but not limited to, that such communications be in writing.
If you request a login code by text message, we will send a one-time passcode to authenticate access to your account. These messages are transactional and are sent only when you request them (or as necessary to support account security). Message and data rates may apply.
TaxExtension.org may use your mobile number to provide text message alerts for product information, tips or promotions, or other marketing activities, if you expressly consent. By providing your mobile phone number and opting in where required, you expressly consent to receive automated marketing text messages from us to the mobile phone number provided. Message and data rates may apply; please check the rates of your mobile carrier.
You can opt out of further text marketing communications by texting STOP in response to a marketing text. After you send STOP, we will send an SMS message to confirm that you have been unsubscribed. After this, you will no longer receive marketing SMS messages from us, unless you sign up again. For assistance, reply HELP or email: [email protected]. Carriers are not liable for delayed or undelivered messages. Message frequency varies. As always, message and data rates may apply for any messages sent to you from us and to us from you. If you have questions about your text plan or data plan, contact your wireless provider. If you have any questions regarding privacy, please refer to our Privacy Policy.
If you choose to file your federal tax return extension application electronically, your information will be converted to and stored in a standardized format, and then transmitted to the IRS. You are responsible for verifying the status of your tax return extension application to confirm that it has been received and accepted by the IRS and, if necessary, for filing it manually in the event that the IRS rejects your electronically filed tax return extension application for any reason. You agree to review your tax return extension application for indications of obvious errors before electronically filing or mailing it. We may, but are not obligated to, store and maintain information that you provide. We are not required or obligated to provide you with copies of this information. If you require a copy of your tax return extension application, you must contact the IRS. The IRS requires InterSearch Tax Solutions, Inc. to provide certain information in connection with the electronic filing of your tax return extension application, including the Internet Protocol (“IP”) information of the computer from which the application originated and whether the email address of the person electronically filing the application has been collected. By using the Services to prepare and submit your tax return extension application, you consent to the disclosure to the IRS of all information relating to your use of the Software and Services as required for e-file processing. Completion and submission may vary due to technical problems with our systems or where you have not provided all necessary information requested by us or required to submit your tax return extension application. For these or other reasons, we may not be able to submit your tax return extension application in a timely manner, or at all. We reserve the right to refuse to make the Software available to you or to provide the Services to you for any reason in our discretion and, in such instances, will refund any fees for the applicable Services paid by you to us (subject to the Refund Policy below).

You hereby grant InterSearch Tax Solutions, Inc. a perpetual, worldwide, fully transferable, irrevocable, royalty-free license to use, reproduce, modify, create derivative works from, distribute and display the Feedback in any manner for any purpose.

InterSearch Tax Solutions, Inc. and its personnel and affiliates are not accountants or tax advisors and are not providing any tax advice or guidance.

To facilitate Third-Party Services, we may be required to obtain your explicit consent for disclosure and/or use of information you provided to us. By accepting applicable agreements/consents, you authorize us to use and disclose your contact information (including name and address) for the purpose of making the Third-Party Services you choose available to you.

You are responsible for the use of the Software under your user ID. We will not disclose your password if you lose or forget it. If you have not electronically filed or printed your tax return extension application, you must create credentials in order to access your application data at a later date.

(a) Tax Extension Services. Once we have electronically transmitted your tax extension to the IRS, we are under no obligation to issue you a refund. However, if your extension is rejected by the IRS, you can correct and retransmit your extension an unlimited number of times at no additional cost, provided it’s the same IRS extension form and taxpayer or business entity we originally transmitted for you. If the IRS rejects your initial tax extension filing as being too late because they are no longer accepting tax extension applications for that year, we will issue you a full refund upon request. (b) Tax Preparation Services. Fees collected at the time of your tax extension filing to either reserve a tax professional to prepare and file your tax return at a discounted rate OR as payment for returns that will be self-prepared by you are non-refundable once your extension is transmitted to the IRS. However, those fees are credited to the final cost of your tax preparation services provided that the return is filed prior to the final IRS filing deadline for that return type, typically September 15th for most business returns and October 15th for individual returns.
