Is your IR35 position as solid as you think?

Answer five quick questions and get a clear, personalised next step based on your contracting situation.

WHAT I DO

What I handle on your behalf

From your IR35 status assessment through to your annual limited company accounts and corporation tax return, I take care of the whole picture.

01

IR35 Status Review and Ongoing Guidance

I review your working arrangements against HMRC’s key IR35 tests: control, substitution, and mutuality of obligation. If your client sends you a Status Determination Statement, I go through it with you in plain English so you understand exactly where you stand. Getting this right at the start of a contract protects you from the kind of tax bill that arrives years later.

02

Limited Company Accounts and Corporation Tax

If you contract through a personal service company, your annual accounts and corporation tax return need to be filed accurately and on time. I handle both, personally. I also make sure your director salary and dividend structure is set up in a tax-efficient way that is defensible if HMRC looks at it.

03

Tax Planning and Take-Home Optimisation

IR35 directly affects how much you take home. If you are outside IR35, I help you structure your income so you keep more of what you earn within the rules. If you are inside, I explain exactly what that means for your pay and help you plan accordingly. No guesswork, just honest numbers.

Year-round, not just at year-end
WHY IT WORKS

Why contractors stay once they find me

Most contractors have had an accountant who was fine for self assessment but blank-faced when IR35 came up.

You speak to me, not a junior

There are no handoffs at Anchor Accounts and Books. I am the only person who works on your file, so when you have a question about your IR35 position or your accounts, you get an answer from someone who actually knows your situation. That matters when a contract renewal is on the table and you need clarity fast.

Fixed fees, no surprises

You know what you are paying before you start. I do not charge extra every time you send an email or pick up the phone with a question. For contractors who are already watching their take-home shrink inside IR35, that kind of cost certainty is not a small thing.

IR35 is something I actually deal with

A lot of accountants added an IR35 page last year. I have been working with limited company contractors for years, across private and public sector engagements. I use cloud accounting tools including QuickBooks, FreeAgent, Xero and Sage, so I can also set you up properly from the start rather than inheriting a mess.

FROM CLIENTS I WORK WITH

What contractors say

★★★★★

“I had just been handed an inside IR35 determination and had no idea what it meant for my tax. Luke explained it clearly, told me what I actually owed and what I did not, and sorted my limited company accounts at the same time. I wish I had found him sooner.”

★★★★★

“My previous accountant had no idea how to handle IR35. Luke reviewed my contracts, explained the status tests in plain English, and gave me confidence that I was outside IR35 and why. Fast responses every time I have a question.”

R.P.
Management Consultant, PSC Contractor
★★★★★

“Switching to Luke was easier than I expected. He took over my limited company accounts mid-year and sorted out the IR35 position I had been ignoring. Fixed fee, no fuss, and I actually understand what is happening with my tax for the first time.”

GETTING STARTED

How it works

Four straightforward steps, and you can have your IR35 position reviewed and your accounts in order without it taking over your week.

01

Book a free call

You book a free call through the contact page. We talk through your contracting situation, your current IR35 concerns, and what you need from an accountant. No obligation and no jargon.

02

I review your position

I look at your working arrangements, any Status Determination Statement your client has issued, and how your limited company is currently set up. I give you a clear picture of where you stand and what, if anything, needs to change.

03

We agree a fixed fee

Once I understand what you need, I confirm a fixed monthly fee. You know exactly what is included before you commit. If you are switching from another accountant, I handle the transfer directly.

04

I take care of the ongoing work

From that point, I handle your limited company accounts, corporation tax, self assessment, and any IR35 questions that come up during the year. You contact me directly and I respond the same day.

COMMON QUESTIONS

Common questions

If you are outside IR35, you contract through your limited company and can take income as a mix of salary and dividends, which is generally more tax-efficient. If you are inside IR35, your fee from that contract is treated as employment income and taxed accordingly, which typically reduces your take-home pay by 20 to 30 percent. The determination affects every pound you earn from that engagement, so getting it right matters a great deal.
Yes. Since the 2021 private sector reforms, clients in medium and large businesses are responsible for making the determination. However, a contractor can raise a formal disagreement and the client is required to review it. I can look at your SDS, assess whether the determination is well-founded based on your actual working arrangements, and advise you on whether there are grounds to challenge it.
Yes, in most cases. Your limited company still exists and still has filing obligations, including annual accounts and a corporation tax return. Your self assessment will also look different when IR35 applies. I handle all of that, and I also help you think through whether contracting through a PSC still makes financial sense for your situation.
It is never too late to get clarity on where you stand. HMRC can look back at previous tax years if they believe the rules were not followed, which is exactly why it is worth reviewing your position now rather than waiting. I will not judge what happened before. My job is to make sure you are in the right place going forward and to help you understand your actual exposure honestly.
