HMRC's CEST Tool Gets It Wrong.
You Can't Afford To.
HMRC's Check Employment Status for Tax tool returns "unable to determine" in around 1 in 4 cases. It ignores case law. It's been defeated in multiple tribunals. Here's what you're relying on vs what you could use:
- 16 questions — surface-level assessment
- Zero case law — ignores tribunal decisions
- ~75% determinacy — 1 in 4 get no answer
- No explanation — just a result with no reasoning
- No next steps — leaves you on your own
- 15+ weighted questions across all three employment tests
- 30+ case law references — Atholl House, PGMOL, and more
- Clear risk rating — green, amber, or red with confidence level
- Detailed reasoning — which tests you pass or fail, and why
- Personalised next steps — insurance, umbrella, or specialist review

Built on Independence, Not Sales Targets
In a market where every provider has something to sell you, we built something different. We have no insurance product. No accounting service. No umbrella company. We have information to give you.
Case Law Grounded
Every assessment references specific tribunal decisions — Atholl House (2022), PGMOL (2023), Ready Mixed Concrete (1968). Not vague generalities. Not marketing speak. Actual case law that tribunals use.
Genuinely Independent
We don't sell insurance, accounting, or umbrella services. We recommend them. There's a difference. When the right answer is "you don't need this product," we'll tell you that.
Transparent About Money
We earn affiliate commissions when you follow our recommendations to insurers, accountants, or umbrella companies. That's how we keep everything free. We'll always tell you this, on every page.
Always Current
IR35 law changes. New tribunal decisions shift the landscape. Every piece of content carries a "last reviewed" date and updates within two weeks of any legislative change. You'll never rely on stale information.
Built for Contractors Like You
Whether you're new to contracting, affected by the April 2026 changes, or renewing a contract.

IR35 is confusing. We explain it in plain English, show you the financial impact, and help you make informed decisions from day one.
