Sound familiar?
Still not sure what your tax bill is going to be?
Most limited company directors only find out what they owe when the year-end bill lands — often with days to spare. The deadline is fixed, HMRC penalties start immediately, and the chances of claiming every allowable relief shrink the longer things are left. It does not need to work that way.
- Tax liability unknown until the deadline is almost upon you
- Late filing penalties building up because no one flagged the deadline
- Allowable expenses missed because the records were not organised in time
What a properly handled return looks like
Your accounts are prepared, your liability is calculated well in advance, and the CT600 is filed before HMRC needs to remind you. Expenses are reviewed properly so nothing claimable is left on the table.
- Your tax liability calculated and communicated months before it falls due
- CT600 filed on time — deadline tracked and managed without chasing you
- Allowable expenses and available reliefs reviewed and correctly claimed
- Fixed fee agreed upfront — no surprise invoices alongside the tax bill

Everything your corporation tax return needs
From preparing the underlying accounts to filing the CT600, the full process is covered. Nothing is left for you to chase or coordinate.
Year-End Accounts Preparation
Your statutory accounts are prepared from your bookkeeping records, reviewed for accuracy, and finalised ready for Companies House and HMRC. Directors know what the numbers say before anyone else does. No scrambling to pull records together at the last minute.
Included as standardCT600 Filing with HMRC
The corporation tax return is prepared, checked, and submitted to HMRC before the nine-month deadline. Your tax liability is calculated correctly, with all allowable deductions applied. You receive confirmation of filing and a clear figure of what is owed and when.
Included as standardTax Planning Throughout the Year
Rather than calculating the damage after year-end, we flag the expected liability well in advance so you can plan your cashflow accordingly. Where reliefs such as capital allowances or R&D credits apply, these are identified before the return is filed — not discovered after.

Why limited company directors choose us
There are plenty of accountants who will file your return. Fewer who will make sure you understand it, plan around it, and never feel blindsided by it.
Your tax bill, known in advance
Corporation tax should not be a surprise. We calculate your expected liability well before year-end and let you know the figure with enough time to plan your cashflow. You are not finding out what you owe the week before it falls due.
No compliance box left unticked
Year-end accounts, CT600, and Companies House filing are coordinated together so nothing falls through the gap between them. Deadlines are tracked and managed — you will not receive a late filing penalty notice because something was missed. Which is, frankly, the way it should be.
Plain-English explanations, always
Your return is explained in straightforward terms — what the figures mean, what you owe, and why. Questions get answered the day you ask them. You will not need a second accountant to translate what the first one filed.
Up and running in four steps
Getting your corporation tax handled properly does not require a lengthy onboarding process. Most clients are set up and have a clear picture within a week.
Get in touch
Call, email, or use the contact form — we reply the same day. Tell us your company’s year-end date and roughly where your records stand. That is all we need to get started.
Free initial conversation
We discuss your situation, explain what is involved, and give you a fixed fee. No pressure, no obligation. You leave the call knowing exactly what happens next and what it costs.
We prepare your accounts
Once engaged, we work from your bookkeeping records — whether tidy or in some state of disarray. Catch-up work is handled without drama. You do not need to have everything perfect before coming to us.
Filed, confirmed, done
Your CT600 is filed with HMRC and you receive confirmation. You know what you owe, when it is due, and what to expect next year. Corporation tax becomes a managed item on your calendar rather than an annual worry.
“We have been working with Hasan for almost a year. He’s been very helpful providing us with knowledge as new business owners. It’s great we can WhatsApp for general queries, making communication more efficient.”
Things people usually ask us first
What rate of corporation tax will my company pay?
The main rate of corporation tax is currently 25% for companies with profits above £250,000. Companies with profits up to £50,000 pay the small profits rate of 19%. There is a tapered marginal relief for profits between the two thresholds. We will calculate your position accurately and flag which rate applies to your company before the return is filed.
What is included in the fee, and how is it priced?
The fixed fee covers preparation of your statutory year-end accounts, calculation of your corporation tax liability, preparation and filing of the CT600 with HMRC, and Companies House submission. Everything is agreed upfront so there is no invoice waiting for you alongside the tax bill. Pricing depends on your company’s size and the state of your bookkeeping records — we will confirm the figure on the initial call.
My previous accountant left the books in a state. Can you take over mid-year?
Yes, and this is fairly common. We review what exists, identify what is missing, and catch up the records before preparing the accounts. Catch-up work is scoped and priced separately from the ongoing fee so you know what the additional cost is before we start. Clients usually arrive with books in some state of disarray and leave with considerably less to worry about.
Am I tied in? What if I want to leave?
There is no long-term contract. If the arrangement is not working for you, you are free to leave at any time. We will prepare a handover pack for your incoming accountant so the transition does not cost you time or create a gap in your compliance record. You keep your accounts and all your records — they are yours.
What is the deadline for filing a corporation tax return?
The CT600 must be filed with HMRC within twelve months of your company’s accounting period end. Corporation tax itself is generally payable nine months and one day after the period end. We track both deadlines and alert you well in advance — you will not discover a missed deadline by receiving a penalty notice.
Can you help reduce my corporation tax bill legally?
Yes. Common reliefs include capital allowances on equipment and vehicles, the annual investment allowance, R&D tax credits for qualifying companies, and careful structuring of director remuneration. These are reviewed as part of the return process, not as an afterthought. Identifying them before year-end — rather than after — is where the difference is made.
