HMRC Audit & Sandbox Notice
This application is currently operating in a Sandbox / Pre-Production environment for testing and HMRC auditing purposes. While current testing infrastructure utilizes secure EEA-based cloud processing, upon receiving HMRC production credentials, our entire architecture will be migrated exclusively to a UK-based data center (e.g., AWS London) to permanently fulfill the UK-exclusive data processing clauses outlined below.
1. How Our Service Works
Invisible Accountant is a software application designed to assist UK sole traders with their tax obligations under the Making Tax Digital (MTD) initiative. By messaging our dedicated WhatsApp number with text or images of your business receipts, our AI engine extracts the financial data, categorizes it, and queues it for submission. Upon your explicit confirmation, we transmit this data to HM Revenue & Customs (HMRC) via their official APIs.
2. Our Responsibilities
We are responsible for maintaining the security, uptime, and strict data separation of your account. We commit to processing your data in accordance with our Privacy Policy and all applicable UK GDPR regulations. We will transmit your approved data to HMRC accurately as confirmed by you.
3. Your Responsibilities as a Customer
While our AI engine is designed to accurately extract data, you are ultimately responsible for the accuracy of your tax submissions and your overall tax liability. You must review and confirm the extracted vendor, amount, and category before authorizing us to submit the data to HMRC.
You agree not to use the service for fraudulent purposes or submit fabricated financial documents.
4. HMRC Interaction & OAuth Grant
To use our service, you must authorize Invisible Accountant to interact with HMRC on your behalf using an OAuth 2.0 grant. This authorization lasts for 18 months. You may revoke this access at any time via your HMRC Government Gateway portal or by terminating your account with us.
Note: Our software submits data to HMRC via their official APIs. We adhere strictly to HMRC Developer Hub guidelines. Use of our software does not constitute formal endorsement or "HMRC approval" of your tax affairs.
5. Security Reporting
We take the security of your financial data extremely seriously. If you identify a security vulnerability, suspect a breach, or require assistance, please contact us immediately at security@invisibleaccountant.co.uk. We have a dedicated process to report verified incidents to HMRC and the ICO within 72 hours.
