Terms and Conditions

Last updated: March 2022


Taxes should be understandable to everyone! That’s why we at Taxfix developed our web and mobile based app (collectively, “Apps” and each, an “App“) – to help people do just that. The App allows users to understand, fill out and submit their tax returns in an easy, quick and user-friendly manner.

The following terms and conditions (these “Terms“) govern your access or use of the Apps, and any content, products and services made available by Taxfix Spain S.L. calle Goya 15, piso 6, 28001 Madrid, Spain (“Taxfix“, “we“, “us“, “our“) via either of the Apps or any websites and applications operated by third party cooperation partners (collectively, the “Services“) following your acceptance of these Terms.

Please read these Terms carefully. By accepting these Terms, you agree to be bound hereby. If you do not wish to accept these Terms, you should cease downloading, installing or using the Apps and our Services and/or uninstall the Apps immediately. The Terms will be at user’s disposal at any time to download and store.

Supplemental terms may apply to certain additional services, such as policies for a particular event, activity or campaign, and such supplemental terms will be disclosed to you in connection with the applicable Services. Supplemental terms are in addition to, and shall be deemed a part of, these Terms.

1 – Scope of Services

  1. The Services comprise web and mobile applications and related services, which enable users to prepare, file and submit their tax declarations through the App, as well as to make use of further offers in financial matters and with regard to their tax returns.
  2. Using the App, each user inputs certain relevant data needed to prepare his/her tax return for submission to the tax authorities. The user is asked to answer certain predetermined questions and to provide certain information including with respect to: title, name, marital status, employment, address, religious affiliation, occupation, employer, annual wage tax statement or most recent payroll slip, second household, responsible tax office, tax identification number, education and vocational training, expenses for work equipment, job applications, professional associations, income from capital assets (if a bank statement is available), income from any sale of commodities (excluding income from pension schemes), insurance schemes, health expenses, surviving dependency, disabilities, nursed persons, personal information of children living in the same household, parents or other persons, donations, church tax, household expenses, expenses from pension schemes, permanent expenses, alimony paid to third parties and loss carryforward, as applicable. The App uses the data that is inputted by the user to calculate the user’s tax burden and refund amount (if any). For information about how we process all this information we collect about you, please see our Privacy Policy.
  3. In order to calculate the user’s tax burden, Taxfix needs access to certain pre-fill information that is electronically reported to tax authorities (namely by your employer and the relevant social security office) and stored with them. You need to provide us with any of the means of authentication for the Tax Agency such as your ID number, the reference number of the Tax Agency, the corresponding box relating to the previous income tax return, the last four digits of your bank account’s IBAN or the Cl@ve Pin. You will grant an authorisation in favour of Taxfix to use the authentication method of your choice in order to  securely retrieve via the Tax Agency’s API your pre-fill information which is encrypted via in-transit encryption (SSL) by providing your tax reference number. Once we have received your pre-fill information from the Tax Agency’s API, this information is stored by Taxfix Germany GmbH in your Taxfix account on our servers in order to integrate, so that you can populate this data directly in your tax return.
  4. Following calculation of a user’s tax burden and refund amount, the user may elect to conclude a Service Agreement (as defined and further described in § 2 below) with us and thereby use our Services to generate his/her tax declaration for submission using the Tax Agency’s API. Please note that the preparation of the tax declaration takes place outside the App but uses the data collected in-app by the user. Where a user clicks “Submit to the tax office” in the App, such user authorizes, empowers and instructs Taxfix to submit his/her income tax declaration to the tax authorities via the Tax Agency’s API. To provide the Services, Taxfix adopts the figure of a “social collaborator” with the Tax Agency (Agencia Tributaria) in accordance with Article 92.3 of Law 58/2003, of 17 December, General Taxation (the Spanish General Taxation Act). This social collaborator status enables us to submit tax returns to the Spanish tax authorities on behalf of our users.
  5. Following finalization and submission of a user’s tax declaration, a copy of the submitted tax declaration is made available to the user for download in the App. We will send an email to the user confirming such submission.
  6. Please note that the App calculates a user’s tax burden based on the input of the user and current tax legislation. This allows the App to work out an expected refund or additionally owed tax amount, which, for the sake of clarity, is a non-binding calculation. This value may deviate from the actual refund or additionally owed tax amount, as these values are ultimately determined by the responsible tax office. Our Apps are programmed to calculate these values as accurately as possible. However, we do not warrant or make any representation or guarantee that the tax charge, refund or additional charge calculated by the App is accurate. Should there be any deviation from the final assessment of the tax authorities, we encourage our users to reach out to us at [email protected] and let us know, so that we can improve our Services.
  7. Notwithstanding anything stated in these Terms, please note that none of the Services include or constitute, nor does Taxfix claim to offer, tax advisory or consulting services. Taxfix limits its activities to those of a social collaborator with the Tax Agency. If you have any specific tax or legal questions, we recommend that you seek advice from a tax or legal advisor.
  8. Use of the App and other Services may be available through a mobile device, whose use may be subject to additional charges or fees imposed by third parties such as (for example) the telecommunications carrier you have engaged with. Each user is solely responsible for any such additional charges or fees and for the terms of any separate agreement with his/her mobile device and service provider.
  9. Please note that the Services are not available in the following regions of Spain: Basque Country, and Navarra.

2 – Formation of Service Agreement

  1. You engage our Services by downloading, accessing or using the App. After you have completed the question flow in the App to calculate either your tax refund or owed amount, you can elect to have Taxfix submit your tax declaration to the tax authorities on your behalf. You will be asked to enter your bank information (“Bank Details“) in order for the tax office to wire you your refund amount or to collect any owed amount, as applicable.
  2. For the submission of your tax declaration, we charge a one-time submission fee (the “Fee”) including statutory VAT. By clicking on “Pay now”, you (i) accept our offer to conclude a contract of service (a “Service Agreement”) pertaining to the submission of your tax declaration in accordance with these Terms and (ii) undertake to make the relevant payment in the amount of the Fee displayed via credit card. Payments are processed by Stripe Payments Europe (Stripe), our payment service provider.
  3. Your Service Agreement is with Taxfix.
  4. Your contract with us regarding your use and your access to the Apps in accordance with these Terms otherwise comes into effect upon your confirmation of these Terms.

  2. The right of withdrawal expires according to Article 103 of the Spanish Consumer Protection Laws also if Taxfix has completely rendered the service and has only started with the performance of the service after you have given your explicit consent and at the same time confirmed your knowledge that you lose your right of withdrawal when Taxfix has completely fulfilled the contract (e.g. if Taxfix has submitted your tax return to the Tax Agency).

10 – Miscellaneous Provisions

  1. Taxfix may amend these Terms, any policies or supplemental terms related to the Services (collectively, the “Provisions“) from time to time. Such amended Provisions will then apply to each agreement we conclude with you.
  2. If we wish to amend any Provisions of an ongoing agreement with you for the future, the following shall apply:
    1. Subject to subsections (b) and (c) below, we will inform you about the planned changes in the event of any material change to any Provision that detrimentally affects your rights under these Terms, before such change goes into effect. If you do not object within 6 weeks or, if after expiry of this period, you continue to access or use the Services, this shall constitute your consent to be bound by the Provisions, as amended. In our notice to you we will inform you of your right of cancellation, the deadline and the consequences of your silence.
    2. Subsection (a) shall not apply to amendments to either the subject matter of an agreement or any material obligation which would result in a material change to the contractual structure as a whole. In this case, we can make you an offer to continue a contract with our new provisions.
    3. We also reserve the right to adapt or modify any Provisions with effect for the future if: (i) the changes or modifications are solely beneficial to users; (ii) the changes or modifications are necessary to comply with applicable law, including but not limited to if the applicable law changes or to comply with a court judgment or order by a public authority; (iii) the changes or modifications have no material effect on the functionality of the Services or are of a purely technical or organizational nature; or (iv) we introduce new Services or performances which require a description in the Provisions, unless this would be detrimental to the ongoing contractual relationship (in the latter case, subsection (b) shall apply).

  4. Any terms that apply to a user’s access to and use of the App and any of the other Services that deviate from those provided herein are only valid where expressly agreed to in writing; individual agreements shall remain unaffected.
  5. A user is only entitled to set off and apply against our claims, such amounts owed by Taxfix arising from counterclaims that are undisputed or have been finally adjudicated by a court of competent jurisdiction.
  6. Should individual clauses of these Terms be or become invalid in whole or in part, these Terms shall otherwise remain valid. In the event of such invalidity, the invalid provision shall be replaced by the statutory provision, if any.
