Disclaimer

1. What TaxPilot Is

TaxPilot is a Chrome extension that provides AI-powered assistance for completing UK Self Assessment tax returns. Responses are grounded in official HMRC guidance documents and designed to help you understand your return in plain English.

TaxPilot is a technology product, not a regulated financial or tax adviser. It is developed and operated by Phil Vamplew (trading as TaxPilot), an individual not registered with ICAEW, CIOT, ATT, or any other UK professional tax body.

2. Not Tax or Financial Advice

TaxPilot's AI responses are informational only. They reflect general interpretations of HMRC guidance and may not account for your specific circumstances, including but not limited to:

• Complex employment arrangements or multiple income streams
• Non-domicile or non-residence tax positions
• Trusts, estates, or inheritance tax matters
• Business profits, partnerships, or self-employment edge cases
• Share scheme interactions with other reliefs
• Prior tax years, enquiries, or HMRC disputes

3. Your Responsibility

You remain solely responsible for the accuracy and completeness of your Self Assessment return. Submitting incorrect or incomplete information to HMRC may result in penalties, interest charges, or further investigation — regardless of whether you used TaxPilot.

Before submitting your return, you should:

• Review all figures independently against your source documents (P60, P45, payslips, bank statements)
• Verify any relief or deduction you intend to claim with HMRC's own guidance or a qualified adviser
• Consult a qualified accountant if your affairs are complex or if you are unsure about any entry

4. No Liability

To the fullest extent permitted by applicable law, TaxPilot and its operators accept no liability for any loss, penalty, interest charge, or other consequence arising from reliance on information provided by the TaxPilot extension or website. This includes errors in AI-generated guidance, incorrect auto-fill suggestions, or misinterpretations of HMRC rules.

Auto-fill suggestions made by TaxPilot must be reviewed and confirmed by you before they are submitted to HMRC. The "Undo" feature is provided precisely for this reason.

5. AI Limitations

TaxPilot uses Google Gemini, a large language model. Like all AI systems, it can make mistakes, misinterpret questions, or provide outdated information if HMRC rules have changed. The system prompt and grounding documents are updated regularly, but there may be a lag between HMRC policy changes and updates to TaxPilot's guidance.

Always cross-reference important guidance against HMRC's official website.

6. Changes to this Disclaimer

We may update this disclaimer from time to time. The date below reflects the last revision. Continued use of TaxPilot after any update constitutes acceptance of the revised disclaimer.
