About these terms

These terms apply when you access or use TaxQuay, operated by Sichys Ventures Ltd, registration number 15372522, with its registered address at 146, Third Avenue, Dagenham RM10 9BB. If you use TaxQuay for an organisation, you confirm that you have authority to accept these terms for it.

Sandbox notice: TaxQuay has not yet completed HMRC’s recognition process. The current service is for sandbox testing and must not be relied on to file a live production VAT return.

Accounts and access

You must provide accurate information, protect your credentials, use two-factor authentication where appropriate and notify us promptly about suspected unauthorised access. Organisation owners are responsible for invitations, role assignments and removing access that is no longer needed.

Your responsibilities

You remain responsible for your accounting records, VAT treatment, return figures, deadlines, client authority and all information submitted to HMRC. You must review every return and make the applicable legal declaration before submission. TaxQuay is software and does not provide tax, accounting or legal advice.

You must not misuse the service, interfere with its security, attempt to access another customer’s information, upload malicious content, reverse engineer protected components, or use TaxQuay for unlawful or fraudulent activity.

HMRC connections and submissions

You authorise TaxQuay to communicate with HMRC only when you complete HMRC’s own OAuth authorisation process. We do not store your Government Gateway password. HMRC controls its services, obligation dates, acceptance decisions, payment records and API availability.

An agent must hold the appropriate authority and obtain client approval before submitting a return. A submission receipt records the API response but does not remove the user’s responsibility for the return.

Corrections and records

Submitted VAT returns cannot simply be overwritten. TaxQuay may provide workflow assistance based on published HMRC correction routes, but users must determine the correct treatment and seek professional advice where appropriate. Users are responsible for retaining records for the legally required period.

Availability and changes

We aim to provide a reliable service but cannot guarantee uninterrupted availability, including where HMRC or infrastructure services are unavailable. We may make changes needed for security, law, HMRC API specifications or product improvement. Material changes to these terms will be communicated appropriately.

Data and intellectual property

You retain rights in data you upload. You give us permission to process it only as needed to provide, secure and improve the service and comply with law. TaxQuay’s software, content, design and branding remain protected by applicable intellectual-property rights.

Liability

Nothing in these terms excludes liability that cannot legally be excluded. Subject to that, the final commercial terms will specify appropriate limitations for loss arising from inaccurate customer data, missed deadlines, tax decisions, third-party services and indirect losses. These limitations will be completed and legally reviewed before paid production service begins.

Ending use of TaxQuay

You may stop using the service and request account closure. We may suspend access where reasonably necessary for security, suspected misuse, legal compliance or material breach. Data export, retention and deletion will follow the privacy policy and applicable law.

Governing law

Unless your final service agreement states otherwise, these terms are governed by the laws of England and Wales and disputes are subject to the courts of England and Wales.
