What Is IR35?

IR35 is a set of tax rules designed to stop contractors working like employees but paying less tax through a limited company.
If HMRC decides you’re “inside IR35,” you could:

Pay more in tax and National Insurance

Face backdated tax bills
Lose the ability to take income as dividends
Buzz helps you understand where you stand — and how to protect your income.

Inside or Outside IR35?

Buzz doesn’t give legal status determinations — but we help you understand the key tests:

Control: Do you decide how, when, and where you work?

Substitution: Can you send someone else to do the work?

Mutuality of Obligation: Are you required to accept work? Are they required to give it?

We’ll show you what to watch for and what to flag with your client or legal advisor.

What If You’re Inside IR35?

If your contract is inside IR35:

You may be taxed as if you’re employed

Your client or agency might deduct PAYE at source
You may still run your limited company — but with less flexibility
Buzz helps you stay compliant, plan your income, and keep your books clean either way.
