Terms of Service

Effective May 17, 2026

These Terms govern your use of the Atamatax tax-filing service at atamatax.com(the "Service") operated by Atamatax — raison individuelle, Suisse (registration pending CHF 100k revenue threshold). By creating an account or using the Service you agree to these Terms.

What we are (and what we are not)

Atamatax is a software preparer in the same category as TurboTax. Today we generate a draft PDF package from the inputs you provide and confirm: your figures mapped to each IRS form and line, with open items called out for review. Until our integrated e-file via an authorised IRS Electronic Return Originator (ERO) ships (target Q3 2026), you use that package to complete and submit the official forms by mail or IRS Free Fillable Forms. Once integrated e-file is live, we will transmit your return to the IRS Modernized e-File (MeF) system and FinCEN BSA through an authorised ERO partner.

Atamatax is not a CPA firm, a tax attorney, a financial advisor, or a registered investment adviser. We do not provide individualized tax, legal, or financial advice. For situations the Service cannot handle (entities, trusts, IRS examinations, etc.) we may refer you to a partner CPA but the retainer is between you and the CPA.

Eligibility & accuracy of inputs

You must be at least 18 years old and either a US citizen or US green-card holder. You are responsible for the accuracy and completeness of every number, election, and attestation you give us. The Service will sometimes auto-fill values (e.g. PFIC classification from ISIN, holdings from Plaid). Those auto-fills are suggestions derived from external data sources and you are responsible for reviewing and confirming them before you rely on the package or approve electronic transmission after that feature is live.

Plaid & brokerage data

You can authorize Atamatax to import your brokerage holdings and transactions through Plaid. By doing so you also agree to Plaid's End User Privacy Policy and Plaid's End User Terms. You can revoke that authorization at any time from your brokerage portal or by emailing us; revocation does not remove the data we already imported, only the future ability to refresh.

Payment

Atamatax is free until you generate your draft package. When you choose to generate it, you authorize a one-time charge in US dollars through Stripe (Simple $299, PFIC $499, Complex $799).

Until integrated e-file via an authorised IRS Electronic Return Originator (ERO) ships (target Q3 2026), we deliver a draft PDF package — your figures mapped to each IRS form and line — that you use to complete and submit the official forms by mail or IRS Free Fillable Forms. Charges are non-refundable once the package has been delivered to your account. If the delivered package contains a software defect that we cannot fix within fourteen (14) days of being notified in writing, we refund 100%. Once integrated e-file is live, the rejection / resubmission policy below applies: if the IRS rejects the return we resubmit at no cost; if the rejection is permanent and not curable through your inputs, we refund 100%.

No tax advice

The educational copy on Atamatax pages, including treaty desk summaries, PFIC method descriptions, and FAQ entries, is general information about US tax rules. It is not a substitute for advice from a licensed CPA, enrolled agent, or tax attorney. Tax rules change. We will update the Service in good faith but cannot guarantee continuous accuracy.

Disclaimer of warranties

The Service is provided "as is" without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the Service will be uninterrupted or error-free. You use the Service at your own risk.

Limitation of liability

To the maximum extent permitted by law, Atamatax — raison individuelle, Suisse (registration pending CHF 100k revenue threshold)'s total aggregate liability to you for any and all claims arising out of or relating to the Service is limited to the amount you actually paid us for the affected return, with an absolute cap of one thousand US dollars (US $1,000) regardless of cause of action, claim type, or number of incidents. We are not liable for indirect, incidental, consequential, special, exemplary, or punitive damages — including loss of profits, data, goodwill, or tax-position outcomes.

IRS penalties, interest, and assessments are your sole responsibility. The Service computes forms from inputs you provide and confirm; the underlying tax treatment is determined by the IRS and applicable law, not by us. We are not liable for penalties or interest assessed against you for any reason — including but not limited to under-reporting, misclassification of PFIC holdings, late filing, late payment, failure-to-file or failure-to-pay penalties (26 U.S.C. § 6651), FBAR penalties (31 U.S.C. § 5321), or FATCA penalties (26 U.S.C. § 6038D) — unless and only to the extent you prove the assessment resulted directly and exclusively from a software defect in a form we generated and that we failed to correct within fourteen (14) days of written notice. You acknowledge that this limitation is reasonable given the price point of the Service relative to the value of the filings it produces.

Indemnification

You agree to indemnify and hold Atamatax — raison individuelle, Suisse (registration pending CHF 100k revenue threshold), its officers, employees, and contractors harmless from any claim arising out of (a) inputs you provided that turned out to be false, (b) activity on your account by someone you authorized, or (c) your violation of these Terms or applicable law.

Account closure

You can close your account at any time by emailing support@atamatax.com from the address on file. We retain filed returns and related data for 7 years after the relevant tax year (IRS standard). Active credentials and tokens are revoked and deleted within 90 days of account closure.

We may suspend or terminate accounts that we reasonably believe to be fraudulent, are being used to file inaccurate returns, or breach these Terms.

Changes to these Terms

We may update these Terms. Material changes take effect 14 days after we email registered users about them. Continued use after that date is acceptance.

Governing law

These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws rules. Disputes shall be resolved exclusively in the state or federal courts located in New Castle County, Delaware, and you consent to that personal jurisdiction. Nothing in this section prevents either party from seeking injunctive relief in any court of competent jurisdiction.
