Terms of Service

Last updated November 10, 2026

These terms are an agreement between you and Tide Software Inc., a Delaware corporation based in California ("we", "us"), for TideTax at tidetax.com. The general terms on tidesoftwareinc.com say our products may have their own terms: these are TideTax's, and for TideTax they control where the two differ. By using TideTax you agree to them and to our Privacy Policy.

What TideTax is

TideTax is software. It reads the tax documents you give it, calculates your federal and California returns, and fills in the forms. It is not tax, legal or financial advice, and we are not your accountant or lawyer. Using TideTax doesn't create a professional relationship with us.

Your return is yours to check

Review everything before you file it. You decide what to file and you're responsible for it being complete and correct, including anything TideTax read from your documents. We tell you when a return is outside what TideTax handles, but we can't promise to catch every situation.

CPA review

If you ask for CPA review, a licensed CPA (not us) reviews and files your return and is its preparer of record. Their work is governed by their engagement terms with you. We share your return and documents with the CPA to do this. The price ($99 today) is shown before you ask.

AI assistants you connect

You can connect an AI assistant of your choice to your account. It acts for you. You're responsible for what you approve and for what it does with that access, including the answers and changes it makes. We don't control the assistant or what its provider does with your information. Before you file, you confirm anything it set or changed. Signing, paying and filing happen only on TideTax.

Your account

You must be 18 or older and use your own email. Keep access to it secure: anyone who can read your email can sign in as you. Give us accurate information, and only upload documents you have the right to share.

Your information

Your documents and data stay yours. You let us store and process them to run TideTax for you and to improve it, as the Privacy Policy describes. We don't sell them.

Fair use

Don't misuse TideTax: no breaking or probing its security, overloading it, scraping it, copying or reverse engineering it, or using it for anything illegal or for someone else without their permission.

Price

Preparing your return and downloading your federal and California PDFs are free today. Anything paid shows its price before you buy. We may change prices for future purchases.

Changes

We may change TideTax, or these terms. If we change the terms in a way that matters, we'll ask you to accept them the next time you sign in. You can stop using TideTax at any time and delete your account on the Account page. We may suspend accounts that break these terms.

No warranty

TIDETAX IS PROVIDED "AS IS" AND "AS AVAILABLE". TO THE FULLEST EXTENT THE LAW ALLOWS, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY AND NON-INFRINGEMENT. WE DON'T PROMISE THAT TIDETAX WILL BE ERROR-FREE OR UNINTERRUPTED.

Limit of liability

TO THE FULLEST EXTENT THE LAW ALLOWS, WE ARE NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, TAXES, PENALTIES OR INTEREST, ARISING FROM TIDETAX. OUR TOTAL LIABILITY FOR ANY CLAIM IS LIMITED TO THE FEES YOU PAID US FOR TIDETAX IN THE 12 MONTHS BEFORE THE CLAIM. Some places don't allow these limits, so they may not all apply to you.

Disputes

If you have a problem, email us at privacy@tidetax.com first; most things get fixed that way. If we can't resolve it within 30 days, you and we agree to settle any dispute about TideTax by binding individual arbitration under the American Arbitration Association's Consumer Arbitration Rules, instead of in court. Either of us may instead bring an individual claim in small claims court.

You and we each give up the right to a jury trial and to bring or join a class or representative action. If this class-action waiver is found unenforceable for a claim, that claim goes to court, not to class arbitration. Nothing here waives a right to seek public injunctive relief that the law doesn't allow to be waived; such a claim is decided in court after any arbitration. You can opt out of arbitration by emailing privacy@tidetax.com within 30 days of first accepting these terms.

Law

Delaware law governs these terms, and the Federal Arbitration Act governs the arbitration agreement. You keep any protections the consumer laws where you live give you that can't be waived. Claims not arbitrated go to the state or federal courts in Delaware, unless the law where you live lets you sue at home.

California users

You can reach the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs in writing at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by phone at (800) 952-5210.
