Terms of Service

Effective date: July 18, 2026

These Terms of Service (“Terms”) govern your access to and use of TaxNexus (the “Service”), operated by Consult Solutions, an Oakland, California company (“TaxNexus”, “we”, “us”). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. What TaxNexus is (and is not)

TaxNexus is compliance monitoring software. It helps e-commerce sellers track their sales activity against California tax nexus thresholds — including the California Department of Tax and Fee Administration (CDTFA) economic nexus threshold for sales and use tax and the Franchise Tax Board (FTB) “doing business” thresholds for franchise and income tax — and flags potential physical-presence nexus, such as inventory stored in California fulfillment centers.

TaxNexus provides informational tools only and does not constitute tax, legal, or financial advice. Users should consult a qualified tax professional for their specific filing obligations. Outputs from the Service — including nexus risk assessments, penalty estimates, filing checklists, and chatbot responses — are estimates generated by software based on the data you provide and publicly available threshold information. They may be incomplete, out of date, or inapplicable to your specific circumstances.

Use of the Service does not create an accountant-client, attorney-client, or any other professional relationship. You should consult a qualified tax professional before making decisions about registration, filing, or payment of any tax.

2. Eligibility and accounts

You must be at least 18 years old and able to form a binding contract to use the Service. You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. You agree to provide accurate account information and to keep it current.

3. Subscriptions, trials, and billing

The Service is offered as a subscription with the plans and pricing listed at taxnexusapp.com/pricing.

Free trial. New accounts may receive a 14-day free trial. No payment method is required to start a trial. At the end of the trial, continued access requires an active paid subscription.
Billing. Subscriptions are billed in advance on a recurring monthly basis and renew automatically until cancelled. Depending on your location, payment is processed by Stripe or by Lemon Squeezy acting as merchant of record. Where Lemon Squeezy is the merchant of record, your purchase is also subject to Lemon Squeezy’s terms of sale. Prices shown in-app are indicative; the exact amount and currency are confirmed at checkout.
Cancellation. You may cancel at any time from your account settings. Cancellation takes effect at the end of the current billing period, and you retain access until then.
Price changes. We may change subscription pricing with at least 30 days’ notice. Changes apply at your next renewal.
Refunds. Refunds are governed by our Refund Policy.

4. Your data and responsibilities

The accuracy of the Service’s outputs depends on the accuracy and completeness of the sales, inventory, and business data you provide or connect. You are solely responsible for:

the accuracy of the data you supply;
verifying any output before relying on it;
your own tax registration, collection, filing, and payment obligations; and
compliance with applicable laws in your use of the Service.

5. Acceptable use

You agree not to: (a) use the Service for any unlawful purpose; (b) attempt to gain unauthorized access to the Service or its systems; (c) reverse engineer, scrape, or copy the Service except as permitted by law; (d) resell or sublicense the Service without our written consent; (e) interfere with the operation or security of the Service; or (f) use the Service to develop a competing product.

6. Intellectual property

The Service, including its software, design, content, and trademarks, is owned by Consult Solutions and protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for your internal business purposes during your subscription. You retain all rights to the data you submit; you grant us a limited license to process that data solely to provide and improve the Service.

7. Third-party services

The Service integrates with or relies on third-party services (for example, payment processors, hosting providers, email delivery, and AI model providers used to power in-app assistance). We are not responsible for third-party services, and your use of them may be subject to their own terms.

8. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE. WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT ANY NEXUS ASSESSMENT, THRESHOLD CALCULATION, PENALTY ESTIMATE, OR OTHER OUTPUT IS ACCURATE, COMPLETE, OR CURRENT, OR THAT USE OF THE SERVICE WILL SATISFY ANY TAX OBLIGATION.

Tax laws and thresholds change. Indexed thresholds are updated by government agencies on their own schedules, and there may be delays before such changes are reflected in the Service.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, CONSULT SOLUTIONS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY TAXES, PENALTIES, INTEREST, OR ASSESSMENTS IMPOSED BY ANY TAX AUTHORITY, OR FOR LOST PROFITS, REVENUE, OR DATA, ARISING FROM OR RELATED TO YOUR USE OF THE SERVICE. OUR TOTAL AGGREGATE LIABILITY FOR ANY CLAIM ARISING OUT OF THESE TERMS OR THE SERVICE WILL NOT EXCEED THE AMOUNTS YOU PAID US FOR THE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM.

Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

10. Indemnification

You agree to indemnify and hold harmless Consult Solutions from claims, damages, and expenses (including reasonable attorneys’ fees) arising from your data, your use of the Service, or your violation of these Terms.

11. Termination

We may suspend or terminate your access to the Service for violation of these Terms or for non-payment. You may stop using the Service and cancel your subscription at any time. Sections that by their nature should survive termination (including Sections 6, 8, 9, and 10) will survive.

12. Changes to these Terms

We may update these Terms from time to time. If changes are material, we will provide notice (for example, by email or in-app notice) at least 14 days before they take effect. Continued use of the Service after the effective date constitutes acceptance.

13. Governing law and disputes

These Terms are governed by the laws of the State of California, without regard to conflict-of-law principles. Any dispute will be resolved in the state or federal courts located in Alameda County, California, and you consent to their jurisdiction.
