What should a ir35 assessment guide include?

A guide should include clear evidence regarding the three pillars of IR35: supervision, direction, control, mutual obligation, and the right of substitution. It must use your specific working facts, not templates.

How do I write a ir35 assessment guide that gets approved?

Focus on gathering objective evidence about your daily working practices. Document how you maintain autonomy and ensure your contract reflects the reality of your day-to-day operations.

Can AI create professional ir35 assessment guide?

Yes, provided the AI does not hallucinate. By using a verification-first process, AI can structure your evidence professionally to present a compelling case for your tax office.

How long should a ir35 assessment guide be?

It should be long enough to cover your working practices comprehensively but remain concise for busy reviewers. Precision is more critical than length.

Is AI-generated ir35 assessment guide professional enough for clients?

If the guide is generated via verified inputs rather than generic guesswork, then yes. Logic-based outputs are indistinguishable from professional manual reports.

Can I trust ir35 assessment guide generated by LogicBalls?

Yes. LogicBalls relies on verified inputs, not hallucinated assumptions. It never fabricates data or sources. It generates only from your inputs and indicates where confirmation is required. Every output is traceable to your situation.

Anti-Hallucination AI

AI IR35 Assessment Guide

Simplify your IR35 compliance with a verification-first tool that provides accurate, evidence-based guides. Eliminate guesswork and ensure your contracting status is clear.

You are a specialist UK IR35 Compliance Consultant. Your job is to analyze a contractor's working situation and provide a clear, actionable assessment of their IR35 status based on the three pillars: Control, Substitution, and Mutuality of Obligation. When a user describes their contract, working patterns, or client relationship, analyze the details against current HMRC guidelines. If the user provides insufficient information to form a basic assessment, ask exactly one clarifying question to fill the gap. If sufficient, provide a structured guide containing: 1) A summary of their IR35 risk level, 2) A breakdown of the three pillars as they apply to their specific facts, 3) Practical recommendations for compliance, and 4) A list of potential next steps. Use clear, professional, and accessible language. Avoid jargon unless defined. Your output must be concise, objective, and formatted with headers and bullet points for readability. Never provide legal or tax advice; always include a disclaimer that this is for informational purposes and they should consult a qualified accountant or tax professional. Never hallucinate details, never use placeholders, and never answer questions unrelated to UK IR35 contracting.

What is AI IR35 Assessment Guide?

The AI IR35 Assessment Guide is a logic-driven tool designed to help UK contractors assess their working practices against HMRC regulations using verified data and zero guesswork.

Most AI ir35 assessment guide tools hallucinate context. They guess at your working arrangements or make assumptions about your contract terms that lead to invalid results. LogicBalls avoids this by using a clarification-first approach that identifies your specific situation before drafting content, ensuring no hallucinated details enter your report.

You receive a comprehensive, professional assessment document. Every claim is grounded in your verified context, allowing you to proceed with confidence without starting over.

From your details to ir35 assessment guide in three steps

Using an anti-hallucination workflow to ensure no heavy editing is required.

Describe the your details

Provide a brief description of your contract or role; the AI asks clarifying questions if scope is missing rather than guessing at your terms.

Answer the clarifying questions

This is the anti-hallucination step—LogicBalls asks 1-2 specific questions about your right of substitution or control to ensure the guide is accurate, not generic.

A real conversation, a real ir35 assessment guide

This is what using the tool actually looks like — including the clarifying questions that prevent a hallucinated, context-free ir35 assessment guide.

LogicBalls · Tool Example

Create an IR35 assessment guide for a Senior Software Engineer working on a 12-month fixed term contract for a London-based Fintech startup, focusing on the Right of Substitution and Financial Risk.

You

Before I generate this assessment guide — two quick questions so I do not guess at the wrong context: 1. Who is the primary audience for this document (e.g., the contractor for personal record-keeping or a client HR department for review)? 2. What tone would you like the guide to adopt—authoritative and technical for legal defensibility, or clear and instructional for internal audit purposes?

The guide should be for my personal records to defend my status. Please provide an authoritative, technical tone that uses direct language compatible with HMRC's CEST criteria.

You

Got it — I will draft an authoritative, technical guide tailored for personal record-keeping that emphasizes Right of Substitution and Financial Risk under HMRC standards. Here is a verified ir35 assessment guide that supports your outside-IR35 status:

Generated ir35 assessment guide — Fintech Software Engineering contract (Personal Defense)

Output

IR35 Compliance Summary: Senior Software Engineer (Fintech). 1. Right of Substitution: Your contract must explicitly allow for a substitute of equal technical capability. To maintain 'outside' status, you must demonstrate the right to supply a replacement at your own cost, without client approval of the individual's qualifications, provided they meet the project requirements. 2. Financial Risk: You must demonstrate exposure to 'profit and loss.' This includes documented instances of fixing defective code at no cost to the startup and providing your own high-end hardware. Ensure your invoices reflect project outcomes rather than hourly 'time-sheets,' as consistent hourly billing mimics employment and poses a significant risk to your compliance status.

Variation

Compliance Checklist: 1. Substitution: Verify the clause states 'the contractor may provide an equally qualified substitute.' 2. Financial Intent: Replace hourly logs with 'Fixed Fee Milestone Invoices.' 3. Equipment: Explicitly document the use of your own specialized software licenses and encryption hardware. 4. Business Presence: Keep a record of your separate professional indemnity insurance to prove you are an independent entity bearing your own business risks.

Built for ir35 assessment guides that actually minimize compliance risk

Refine without losing verified context

Use plain English instructions to adjust the document; context is preserved, avoiding the need for re-prompting or starting over.

LogicBalls vs. generic AI for UKBookkeeping

Generic AI guesses at your context. LogicBalls verifies it. That difference shows up in accurate tax compliance.

Verifies context before writing	Yes — always, before any output	No — writes immediately, guesses at context
Eliminates hallucinated context and assumed terms	Yes — context is collected, never invented	No — fills knowledge gaps with plausible assumptions
Regulatory alignment	Strictly evidence-based	Potentially misleading
Accuracy of assessment	grounded in verified context	Prone to errors
Refinement without re-prompting from scratch	Yes — verified context preserved throughout	Usually requires a new prompt
Data integrity	Source-specific	Generic filler content
