Corporation Tax Returns
Your Corporation Tax return, handled properly.
Most limited company directors find out their tax bill when the return is almost due — which is not a great position to plan from. OD Accountants prepares and files your Corporation Tax return on a fixed fee, handled by a chartered management accountant (FCMA, CGMA), with questions answered the day you ask them.
- Know your Corporation Tax liability months before the payment deadline
- No last-minute scramble — return prepared from clean, current books
- Allowable deductions reviewed as a matter of course, not as an afterthought
- Filed direct with HMRC — confirmation sent to you, nothing left to chase
No long-term contract. If it is not working after three months, you leave with clean books and nothing owed.

Sound familiar?
Still not sure what your tax bill will be this year?
Corporation Tax catches a lot of limited company directors off guard — not because they have done anything wrong, but because no one has been watching the numbers closely enough throughout the year. The return gets filed, the bill arrives, and there is not much room to do anything about it at that point. It does not have to work that way.
- Tax bill arrives as a surprise, with no time left to plan around it
- Not confident that all allowable deductions and reliefs have been claimed
- Return left until the last minute because the year-end books are not ready
What sorted looks like
When your books are current and your return is prepared well ahead of the deadline, the tax bill stops being a surprise and becomes a number you can plan around. Which is, frankly, the way it should be.
- Your liability is calculated and communicated well before the payment date
- Allowable expenses, capital allowances and available reliefs reviewed as standard
- Return prepared from up-to-date books — no year-end scramble to reconstruct records
- Fixed fee agreed upfront — no invoice surprises when the return is filed
What limited company clients say about us
OD Accountants works with limited companies across London, Somerset and remotely across the UK. Here is what two clients say about working with the firm.
My other-half introduced me to Niall at OD Accountants and I have to say my finances are so much the better for it. Unlike my previous Accountants, Niall is far more hands-on, available for advice and able to care for me as an individual, rather than a faceless client. 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.
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.
What the Corporation Tax service covers
The engagement is designed to remove the return from your to-do list entirely — preparation, review, filing and confirmation, handled at a fixed monthly fee.
Your Tax Liability, Calculated Early
Your Corporation Tax liability is calculated from your year-end accounts as soon as the numbers are finalised — not the week before the deadline. That gives you time to plan cash flow around the payment date rather than reacting to it. Directors are notified of the figure in plain English, not buried in a set of statutory accounts.
Included as standardReliefs And Allowances Reviewed
Capital allowances, R&D relief where applicable, director expenses and other deductible items are reviewed as part of every return — not only if you ask. The goal is to arrive at the correct, lowest-compliant liability, not simply the quickest one to file. OD Accountants is a chartered management accounting firm; the depth of review reflects that.
Included as standardFiled Direct With HMRC
The return is submitted directly to HMRC by OD Accountants on your behalf, with confirmation provided once accepted. As an Authorised Corporate Service Provider (ACSP), the firm handles statutory submissions across the board — Corporation Tax, Companies House filings and more — under one roof. Nothing falls through the gap between your accountant and your company secretary.
ACSP authorisedClients who have stayed for years, not months
Verified Google reviews go back more than a decade. Several clients have been with the firm for seven, ten and eleven years — across a range of sectors and company types.
Above And Beyond On Every Engagement
“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.”
Always On The End Of 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!!”
Confident About Finances And Processes
“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.”
Why this firm over any other accountant
There are plenty of firms that file Corporation Tax returns. Fewer of them will have reviewed your numbers closely enough during the year to make the return genuinely useful.
Tax Visibility Before The Bill Arrives
Corporation Tax should not be the first time you find out what you owe. OD Accountants works from current, cloud-connected books throughout the year — which means your liability is visible well before the payment deadline. That is not a premium add-on. It is how the firm operates.
Chartered Management Accounting Depth
Founder Niall O'Driscoll is a Fellow of the Chartered Institute of Management Accountants (FCMA, CGMA) — a qualification earned in commercial finance roles across SMEs, then 10-plus years of freelance restructure and turnaround work including listed companies. The review of your return reflects that background, not just a compliance checklist.
Cloud-First, Not Paper-Chasing
OD Accountants builds its workflows around modern cloud accounting software — Xero and best-of-breed app integrations. That means your year-end numbers are clean and accessible when it matters, rather than reconstructed from bank statements and a shoebox of receipts. The return gets filed faster and with less back-and-forth.
Up and running in four steps
The process is straightforward. Most clients are onboarded with minimal disruption and the first filing period handled without fuss.
Book A Discovery Call
A short call — usually 20 to 30 minutes — to understand your company structure, current accounting setup and what you need from the engagement. No preparation required on your side. You will leave the call knowing exactly what happens next and what it will cost.
Agree Your Fixed Fee
A fixed-fee proposal is sent following the call. No hourly rates, no surprises on the invoice when the return is filed. If you are switching from another firm, the handover is managed for you — OD Accountants contacts your previous accountant directly to request the relevant records.
Connect Your Accounting Software
Your cloud accounting platform is connected or set up, and any outstanding bookkeeping is brought current. If records are in a state of disarray, that is handled as part of onboarding — it is a common starting point, not an obstacle. You do not need to do the tidying yourself.
Return Filed, Bill Known
Your Corporation Tax return is prepared, reviewed and filed with HMRC. You receive confirmation and a plain-English summary of the liability and payment deadline. Going forward, your tax position is visible throughout the year — not just when the return is due.
“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.”
Common questions about Corporation Tax returns
Do you handle Corporation Tax for companies with more complex structures — group companies, R&D claims, or overseas income?
Yes. Niall O'Driscoll's background includes listed companies and international structures, so the firm is familiar with returns that go beyond the straightforward. If your company has overseas income, intercompany transactions or a potential R&D relief claim, those are reviewed as part of the engagement rather than referred elsewhere. Complexity is flagged and discussed — not ignored and filed around.
What does a Corporation Tax return cost, and what is included?
Fees are fixed and agreed before work begins — there are no hourly rates and the invoice when the return is filed matches the quote. The fee covers preparation of the return from your year-end accounts, review of allowable deductions and reliefs, filing with HMRC and confirmation. Clients in Google reviews describe the pricing as very reasonable, with tax savings that more than cover the fee. An exact quote is provided after a short discovery call.
My books are behind and I am not sure they are ready for a return. Can you still help?
This is a common starting point. If your records need catching up before the return can be prepared, that work is scoped and priced separately — you will know the cost before anything begins. OD Accountants uses cloud accounting software to bring records current efficiently. A disorganised set of books is not a reason to delay filing; it is just part of the onboarding process.
Is there a long-term contract? What happens if I want to leave?
There is no long-term lock-in. If the engagement is not working, you leave with your records in order and nothing outstanding. OD Accountants retains clients because the service is worth keeping, not because an exit is contractually awkward. Several clients in Google reviews have been with the firm for seven, ten and eleven years — which says more than a contract clause would.
When exactly does my Corporation Tax payment need to be made, and how does that tie into when you file the return?
For most small companies, Corporation Tax is due nine months and one day after the end of your accounting period. The return itself must be filed within twelve months of the period end. OD Accountants aims to have your liability calculated — and the return filed — well before either deadline, so you know the payment amount in time to plan cash flow rather than find out at the last moment.
Can you help me understand my tax position throughout the year, not just at year-end?
Yes. Because OD Accountants works from cloud-connected books, your tax position is visible on an ongoing basis rather than revealed only at year-end. If your profitability changes materially during the year — a large contract won or lost, a capital purchase — the likely tax impact can be discussed before it becomes a surprise. This is part of what the firm means by strategic finance support rather than purely compliance.
