5 Reasons to Avoid Using AI for Tax Advice

For restaurant and café owners, the rise of AI in tax advice and self-assessment may look like a tempting shortcut. In fact, according to a recent survey by Taxfix, 59% of UK taxpayers say they will use AI tools to help them complete their self-assessment ahead of the 31 January deadline.


The appeal is obvious: speed, simplicity, and the promise of cutting out the middleman. But that convenience often comes at the expense of accuracy and context. That leads us to why you should not rely on it for full tax advice, especially in the kinds of complex, hospitality-based scenarios we commonly deal with.


Why you should avoid relying solely on AI for tax advice


1. Tax is inherently complex and context-dependent


The food service industry has its own unique tax challenges. From variable staff hours and tronc systems to stock management and supplier contracts, every business operates differently. A generic AI tool may provide plausible general statements, but it cannot dig into your specific setup, identify allowable reliefs, or spot risks that come with running a restaurant.


2. AI can hallucinate or misapply rules


AI tools generate answers based on pattern-matching, not always on verified and current UK tax law. There are documented cases where AI has “invented” legal cases or misquoted legislation. What looks coherent on screen may nonetheless be incorrect or misleading, putting you at risk of errors, missed opportunities, or unnecessary penalties.


3. AI advice tends to be generic, not bespoke


AI tools are designed for standardised tasks such as explaining tax forms or listing allowable expenses. But for hospitality businesses, the detail matters. How do you treat staff meals? How should tips and service charges be recorded? What about VAT on takeaway food? A human adviser can ask the right questions and apply the correct tax treatment for your specific setup. AI simply cannot replicate that level of tailored understanding.


4. Regulatory and compliance risk remains high


Mistakes in tax returns expose you to HMRC queries, fines, and reputational damage. AI lacks accountability and can overlook critical details such as VAT thresholds, capital allowances, or the treatment of seasonal staff. Relying solely on AI increases your exposure, which is why professional oversight remains essential.


5. The value of human oversight and advice adds much more


Beyond filing, a qualified accountant brings insight that AI cannot.


  • Strategic planning, such as how to structure your business, manage cash flow, and claim available reliefs.

  • Sector-specific knowledge, including hospitality VAT rules, payroll, and stock management.

  • Building long-term relationships, understanding your business over time, and offering proactive advice rather than reactive responses.

  • Risk management experience, knowing what HMRC tends to look for in the hospitality sector and helping you stay compliant.


What should you do as a restaurant owner?


Here is a practical framework you can adopt now:


  • Use AI tools only for simple or administrative tasks, such as collecting invoices, tracking deadlines, or summarising basic information.

  • Do not treat AI output as professional advice. Always ask your accountant to review anything AI produces before you act on it.

  • Discuss your setup with your adviser before using AI, so they can flag areas that need bespoke tax guidance such as staff tips, VAT on takeaway sales, or capital investment in kitchen equipment.

  • Keep accurate records of sales, wages, and supplier costs. A human accountant can turn that information into meaningful tax planning, whereas AI cannot reliably interpret irregular or industry-specific items.

  • After filing, review your performance with your accountant. Use AI for data management or reminders, but let your adviser provide the insight and context.

In summary


AI is a powerful tool and increasingly part of how people approach tax. It is fast and convenient, but hospitality tax is rarely straightforward. That is where a human tax adviser adds real value.
