Terms and Conditions

The terms that govern your use of aihtax

Last updated: 25 September 2026

These Terms and Conditions ("Terms") govern your access to and use of the aihtax website and services (the "Service"). By creating an account, accepting an invite, or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Who we are

aihtax provides UK bookkeeping and Making Tax Digital (MTD) software tooling, provided by Sebastian Toke-Nichols, trading as aihtax. References to "we", "us", or "our" mean aihtax. Contact us via the support details provided in the product or at onboarding.

2. The Service

The Service helps you organise bookkeeping records, process receipts and bank data, and prepare or submit information related to HMRC MTD workflows you choose to run. Features may change over time. We may update, suspend, or withdraw parts of the Service for maintenance, security, or operational reasons.

3. Accounts and eligibility

  • You must be at least 18 and able to form a binding contract under UK law
  • You must provide accurate registration details and keep them up to date
  • You are responsible for safeguarding login credentials and any devices you use
  • If you use the Service on behalf of a business or client, you confirm you are authorised to do so

4. Your responsibilities

  • Use the Service only for lawful UK bookkeeping and tax preparation purposes
  • Ensure you are authorised to upload and process documents and bank data
  • Review all figures, categorisations, and outputs before any HMRC submission — filings remain your responsibility
  • Do not share accounts unless the product's multi-user features permit it

5. No tax or legal advice

aihtax is software tooling, not a substitute for a qualified accountant, tax adviser, or solicitor. We do not provide tax, legal, or financial advice. HMRC connections depend on your credentials and HMRC availability. You remain responsible for the accuracy, timing, and compliance of any return or update you submit.

6. Acceptable use

You must not:

  • Probe, access, or interfere with other customers' data or accounts
  • Abuse APIs, attempt unauthorised access, or upload malware
  • Reverse engineer the Service for competitive purposes
  • Use the Service for unlawful, fraudulent, or harmful activity
  • Introduce third-party confidential data without a lawful basis

We may suspend or terminate access, or remove content, where we reasonably believe these Terms have been breached or the platform or other users are at risk.

7. Fees and plans

Some features may be free; others may require a paid plan. Where fees apply, prices, billing periods, and renewal terms will be shown before you purchase. Unless stated otherwise, fees are in GBP and exclusive of VAT. Failure to pay may result in suspension of paid features.

8. Intellectual property

We (and our licensors) own the Service, software, branding, and related intellectual property. You retain ownership of content you upload. You grant us a limited licence to host, process, and display that content solely to provide the Service to you.

9. Data and privacy

How we process personal data is described in our Privacy Policy and Cookie Notice. You must comply with applicable data protection law for any personal data you upload.

10. Availability and changes

We aim to keep the Service available but do not guarantee uninterrupted or error-free operation. We may modify these Terms from time to time. Material changes will be notified in the product or by email where practicable. Continued use after changes take effect constitutes acceptance of the updated Terms.

11. Liability

The Service is provided on an "as is" and "as available" basis to the extent permitted by law. We are not liable for lost profits, filing penalties, tax assessments, or indirect or consequential loss arising from use of the Service. Nothing in these Terms excludes or limits liability that cannot be excluded under UK law (including for death or personal injury caused by negligence, or for fraud).

12. Termination

You may stop using the Service and request account closure at any time. We may suspend or end access if you breach these Terms, fail to pay applicable fees, or if we discontinue the Service. On termination we may delete or export your data in line with the Privacy Notice and any applicable retention rules.

13. Governing law

These Terms are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction, except that consumers may also bring claims in their local UK courts where the law allows.

14. Contact

Questions about these Terms can be raised through the support channel provided in the product or at onboarding. Questions about your personal data go to [email protected]. Security problems go to [email protected] rather than support — see /.well-known/security.txt.
