Protect your contracts and reduce risks with professional IR35 reviews.
IR35 assessments help you understand your status, review key documents, and strengthen your IR35 position.
Find out if your contract and working practices place you inside or outside IR35. Reviews consider how you're paid, how much control the client has, whether you can send a substitute, and how integrated you are into the business.
Experts review your contract to spot IR35 red flags, like substitution clauses or control terms. The wording should reflect how you actually work, or it could be challenged. Contract review is crucial for avoiding IR35 complications because it helps make sure contracts accurately reflect the nature of the working relationship.
Answer a set of questions about how you deliver your work in real life. These insights help build evidence to support or challenge an IR35 determination.
After an IR35 status assessment, an SDS should be created, which details the determination and reasons. If you're unsure about the SDS or how IR35 applies, you can seek expert help to get support.
Some providers offer cover for legal defence and, in some cases, tax owed if HMRC deems you inside IR35. It’s peace of mind if you’re working outside IR35.
If HMRC opens an investigation, you can get expert help to defend your case. This is especially useful in complex contracts or high-value disputes.
Get practical training, guides, and checklists to help you understand the rules and reduce your IR35 risk before signing a contract.
Knowing if you’re inside or outside IR35 helps you optimise your income, stay compliant, and choose the right services for you.
Your questions about IR35 assessments, answered.
Yes. IR35 applies to each contract, not you as a person.
Your client or agency will deduct Income Tax and National Insurance before payment. You’ll get less take-home pay and can’t pay yourself via dividends.
No. When working through an umbrella company, you are considered an employee of that company, and all your income is subject to PAYE deductions for Income Tax and National Insurance. That means IR35 rules don’t apply to umbrella company workers.
Yes. Your IR35 status depends on the specific terms and working practices of each contract, not your job title or company.
Not always. While it's HMRC’s official tool, a professional review gives you stronger evidence.
Yes. Sometimes clients misjudge your contract or working practices and wrongly decide you’re inside IR35 when you should be outside (or vice versa). If you believe the decision is incorrect, you have the right to challenge the SDS. Your client should review it and respond.
HMRC may review your contract, working practices, and any assessments or SDS decisions. Having a professional assessment can help demonstrate you’ve taken “reasonable care”.
Yes. If you believe your client’s SDS is wrong, you can formally dispute it. They’re legally required to review and respond. Having a professional IR35 review strengthens your case.
Strong indicators include a well-drafted contract, clear independence from the client, the ability to substitute someone else, and financial risk. A professional review summarises this evidence in one place, which is useful if HMRC ever asks.
Yes. IR35 is contract-specific and can change depending on the project, client, or how you work day-to-day. If your circumstances change, you should get reassessed to avoid compliance issues or unexpected tax bills.
