Sound familiar?
Running your own company but guessing at the numbers?
IT contractors set up a limited company, start billing, and then spend the next few years hoping the tax position is roughly right. IR35 sits in the background as a nagging uncertainty. The salary and dividend split was set up once and never reviewed. Year-end accounts arrive as a surprise rather than a confirmation of what you already knew.
- ✕ IR35 status on your current contract has never been formally assessed
- ✕ Salary and dividends not structured to minimise your combined tax and NIC
- ✕ Corporation Tax bill unknown until the accountant calls with the number
What a proper contractor accountant looks like
The compliance is handled as a matter of course. The useful part is that you know your tax position in real time, your IR35 risk is understood, and you are not overpaying HMRC because nobody ran the numbers.
- ✓ IR35 status reviewed on each engagement so you contract with confidence
- ✓ Salary and dividend structure set each tax year to reduce your overall bill
- ✓ Corporation Tax calculated and visible well before the payment deadline
- ✓ Fixed monthly fee — no surprise invoices at year-end
What contractors and consultants say
From company formation and first contract through to multi-year engagements — a consistent theme of availability, practical advice and problems resolved.
Been with OD Accountants for over a year now. Niall and the team are brilliant. They helped me set up a company and get everything I needed in place to run my business. I'm a tricky client due to my 'digital nomad' status, but their advice…
The service from OD has been excellent, as has their advice. It's great to have access to a financial team who can guide us with such confidence and seamlessly integrate with our internal team. We always feel well-informed and confident about our financial processes and data. Highly recommend.
Everything a limited company contractor needs
Compliance is covered as standard. The advisory layer — IR35 guidance, salary and dividend planning, real-time tax visibility — is what makes the difference.
Limited Company Accounts and Corporation Tax
Annual statutory accounts prepared and filed, Corporation Tax return submitted, and your Companies House confirmation statement handled directly under the firm's ACSP registration. Your tax liability is calculated and communicated well before HMRC's deadline — not handed to you as a last-minute figure.
Included as standardSalary, Dividends and Self-Assessment
Your director salary and dividend draw is reviewed each tax year against current rates and thresholds, so you are not overpaying NIC or Income Tax unnecessarily. Personal self-assessment is filed on time, with your full tax position visible before the January deadline rather than after it.
Included as standardIR35 and Off-Payroll Guidance
IR35 is not a simple area and the rules differ depending on whether your client is in the public sector, a large private company or a small business. The relevant factors — substitution, control, mutuality of obligation — are reviewed against your actual contract and working arrangements before you commit. You will not be left to work it out alone.
Advisory serviceConsistent across years and client types
Verified Google reviews going back over a decade, covering sole traders, limited companies, consultants, start-ups and SMEs. A few themes recur.
Fees Saved More Than They Cost
“His fees are very reasonable and the money he has saved me more than covers them. If you need an Accountant who cares, Niall and OD Chartered Management Accountants are the way to go.”
Years of Service, Always Available
“I've been there for years and Niall and his team go above and beyond the duties to provide accounting services but also general advices. They are always available if you need anything while charging very competitive prices. I could not recommend them enough.”
Supportive, Clear and Always on the Phone
“Niall and his team are supportive, clear and directional accountants who have supported our small business staff up. They're always on the end of the phone to advise and assist and provide a top service for our accounting needs. Plus they're just nice people which helps too!!”
What makes this firm different for contractors
Most contractor accountants handle the compliance. Fewer will tell you your IR35 position is risky before it becomes a problem, or run your salary and dividend figures before you ask.
IR35 Reviewed Before You Sign
The off-payroll working rules carry real financial risk if a determination is wrong or left unexamined. IR35 status is reviewed against your actual contract terms and working practices — not generic guidance. If a contract looks problematic, you will know before you start, not after HMRC does.
Tax Position Known in Advance
Corporation Tax, personal self-assessment and the salary and dividend split are all calculated with current-year figures rather than reconstructed at year-end. Your tax liability is visible throughout the year, so the payment deadline arrives as a confirmation rather than a shock.
Cloud Accounting That Works Remotely
Contractors rarely work from one place. OD Accountants is built around cloud accounting software and SaaS integrations, so your books stay current wherever you are working. The firm is UK-wide and serves overseas-based and digital-nomad clients — your location is not a constraint.
Up and running in four steps
Most contractors are set up and their books are current within a few days of the initial call. The process is straightforward.
Book a discovery call
A short call to understand your current setup — limited company status, IR35 position, what your books look like and what you actually need. No obligation and no jargon. You will know what working with OD Accountants looks like before the call ends.
Receive a fixed-fee proposal
A clear proposal is sent with a fixed monthly fee covering everything discussed. No variable billing, no year-end surprises. If the scope changes, that is a conversation — not an invoice.
Onboarding and data handover
If you are switching from another accountant, the firm handles the professional clearance and transfer. If your books are behind, a catch-up is scoped and agreed upfront. You do not need to present your records in any particular order.
Your accounts run themselves
Bookkeeping current, IR35 reviewed, salary and dividends planned, Corporation Tax visible. Your year-end is an event you are already prepared for rather than one that catches you out. Which is, frankly, the way it should be.
“As a new start up and having never dealt with an accountant, Niall at OD Accountants has been very welcoming and supportive. All our prior queries and issues have been resolved, and he is always available to meet the needs of our team.”
What contractors usually ask us
Do you actually understand IR35 and off-payroll working — not just the basics?
Yes. The distinction between inside and outside IR35 turns on the specifics of the engagement — substitution rights, direction and control, mutuality of obligation, financial risk. These are reviewed against your actual contract and working arrangements, not a generic checklist. The rules also differ depending on your end client's size and sector, so public sector contracts are assessed differently from private ones.
What does it cost for a contractor accountant, and what is included?
Fees are fixed monthly and priced to cover limited company accounts, Corporation Tax, self-assessment for the director, Companies House filings and ongoing advisory access including IR35 guidance. Clients consistently describe the fees as very reasonable, with tax savings more than covering the cost. An exact figure is confirmed at proposal stage once the scope is clear.
My books are behind and I have been filing my own returns — can you take this on mid-year?
This is a common starting point. A catch-up is scoped and priced separately from the ongoing monthly fee, so you know the cost before any work begins. Books in some state of disarray are not unusual — they are reconciled and brought current as part of the onboarding process.
Is there a long-term contract or a minimum commitment?
No long-term contract. If it is not working after three months, you leave with clean books and nothing owed. Most contractor clients stay for several years — the Google reviews include clients with three, seven, ten and eleven-plus years — but that is a result of the service rather than a contractual obligation.
Can you advise on the VAT Flat Rate Scheme for contractors?
Yes. Whether the Flat Rate Scheme is worth using depends on your day rate, expense profile and the percentage applicable to your trade. It benefits some contractors meaningfully and offers little to others. The position is reviewed as part of the initial engagement and revisited if your circumstances change.
How far in advance will I know what my tax bill is going to be?
Corporation Tax is calculated on current-year figures throughout the year, not reconstructed at year-end. Your personal self-assessment liability — including dividend tax — is also visible well before the January filing deadline. The goal is that payment dates arrive as confirmations of a number you already know, not as new information.
