About Us
TaxGTP was created by a team of accountants, business owners, technologists, and AI enthusiasts who all shared the same frustration:
Why does finding a tax answer sometimes take longer than solving the problem itself?
After years of watching professionals spend countless hours searching through manuals, guidance notes, legislation, bookmarks, PDFs, and websites, we believed there had to be a better way.
So we built one.
Our goal wasn’t to replace accountants. Quite the opposite.
We believe great accountants are more valuable than ever. The challenge is that too much of their time is spent searching for information rather than delivering advice.
TaxGTP was built to change that.
By combining HMRC knowledge with modern artificial intelligence, we created a tool designed to help professionals find answers faster, research more efficiently, and focus on what they do best: helping clients make better decisions.
We’re not a Silicon Valley startup chasing the latest trend.
We’re practical people who understand that accountants care about accuracy, reliability, evidence, and trust.
That’s why every part of TaxGTP is designed around a simple principle:
Give professionals the confidence to find the right answer, faster.
Because while tax legislation may never get simpler, finding the information shouldn’t have to be harder.

About TaxGTP
TaxGTP is the Accountants’ Guided Tax Partner.
Because life’s too short to spend three hours hunting through tax manuals for a paragraph you vaguely remember reading in 2019.
Built on HMRC knowledge and powered by artificial intelligence, TaxGTP helps accountants, tax advisers, bookkeepers, and financial professionals find answers faster, research with confidence, and spend less time searching.
Think of it as a tax assistant that never sleeps, never complains, never asks for annual leave, and can search through mountains of guidance in seconds.
TaxGTP is designed to support professional judgement, not replace it. It helps users navigate HMRC manuals, legislation, guidance, and technical tax topics more efficiently, so more time can be spent helping clients and less time can be spent playing “Where did HMRC hide that paragraph this time?”
Whether you’re dealing with VAT, Corporation Tax, Capital Gains Tax, Employment Taxes, Inheritance Tax, or one of those wonderfully obscure questions that arrives five minutes before a deadline, TaxGTP is there to help.
Saving time, reducing research headaches, and helping professionals get back to the work clients actually pay them for.
Built for accountants.

Features and Benefits
tax matters made simple
Automated tax‑scenario modelling
Upload a client’s financial data and let TaxGTP generate multiple tax‑planning scenarios (e.g., capital‑gains timing, R&D credit eligibility) in a single run, freeing up hours of manual spreadsheet work and delivering higher‑value advice.
Real‑time HMRC query engine
Instant, source‑referenced answers let you respond to client emails or phone calls within seconds, reducing waiting time and increasing perceived responsiveness during busy filing periods.
Batch document generation
Create HMRC letters, compliance reports and client summaries from templates in bulk; the system populates each document with the correct citations, ensuring consistency and cutting repetitive drafting time.
Integrated cross‑border and specialist‑tax modules
Built‑in support for EU VAT OSS, UK‑EU post‑Brexit rules, and complex statutory instruments means you can confidently advise on cross‑border transactions and niche regulations without needing external research tools.
Dynamic knowledge‑graph navigation
The system maps relationships between Legislation and HMRC guidance, allowing you to trace the impact of a rule change across multiple tax areas instantly. This depth of insight boosts client confidence and positions your practice as a trusted authority.
Custom Plugin Integration
The open‑source architecture lets you develop or install plugins that connect TaxGTP directly to popular accounting platforms (e.g., Akaunting, ERPNext, Odoo). This enables seamless data exchange, automated tax‑rule checks, and on‑the‑fly document generation within the tools your practice already uses, boosting efficiency and client service.
Frequently Asked Questions
Still have questions? we’ve got answers
Where does my client data go and who can see it?
All the data stays on the server you control – in a private cloud you own. Only the people you give permission to in your firm can access it. We never send your client information to any third‑party service.
Does the AI learn from my firm’s private documents?
No. TaxGTP uses an externally hosted, enterprise‑licensed diffusion LLM (dLLM) that runs in a secure, private cloud under our enterprise agreement. The model is accessed only for inference and does not retain or transmit any of your firm’s data. All queries are answered using the locally stored copies of HMRC manuals and UK primary legislation; no metadata, query terms, or document contents are sent outside your environment.
How does TaxGTP meet GDPR and UK data‑protection rules?
We encrypt data while it moves (TLS 1.3) and when it’s stored (AES‑256). Because the system runs locally, you retain full control over retention periods, can delete or export data whenever you need – covering the GDPR rights to access and to be forgotten.
Can I see a record of what the system has accessed or changed?
Yes. TaxGTP keeps detailed audit logs of every query, document retrieval, and output generation. You can review these logs at any time, filter by user or date, and export them for compliance reporting. The logs are stored locally and are subject to the same encryption and access‑control policies as all other data.
What prevents accidental data leaks when I generate letters or reports?
Because all HMRC manuals and UK legislation are stored locally within your TaxGTP instance, the system never performs external searches. All processing happens inside your own environment using the enterprise‑licensed dLLM that only accesses this local knowledge base. Consequently, any letters, reports or other outputs remain fully within TaxGTP and your infrastructure, with no data leaving the system.
