Running a healthcare limited company in the UK means each year you must submit a set of financial documents to Companies House and HMRC. This process is called annual accounts preparation.
For the 2026/27 financial year, healthcare businesses face the same statutory obligations as other limited companies, but with added complexity due to sector-specific costs and regulatory requirements.
This guide explains how annual accounts preparation works for healthcare limited companies, including:
- What documents do you need for annual accounts?
- Deadlines to remember,
- How to avoid common mistakes,
- And much more…
Let’s break it down!
What Are Annual Accounts for a Healthcare Limited Company?
Annual accounts preparation involves creating a formal record of your company’s financial activity over the year. They include details of income, expenses, assets, and liabilities. For healthcare providers, this often means tracking patient fees, NHS contracts, medical equipment purchases, and staff salaries.
These are often referred to as statutory annual accounts, as they are legally required for all limited companies in the UK. If you’re small or micro, you may be eligible to file simpler or ‘filleted’ versions of your accounts. This allows you to keep details like your turnover and profit off the public register at Companies House.
What Documents Make Up Your Annual Accounts?
When people talk about annual accounts preparation, they are usually referring to a set of documents rather than a single form. Here is what a standard set of statutory annual accounts for a healthcare limited company looks like:
| Document | What It Shows |
| Balance Sheet | What your company owns (assets) and owes (liabilities) at the year’s end |
| Profit and Loss Account | Your income and expenses over the year, and whether you made a profit or a loss |
| Notes to the Accounts | More detail on specific figures, accounting policies, and any significant transactions |
| Directors’ Report | A brief narrative from the directors about the company’s performance |
| Accountant’s or Auditor’s Report | Confirmation that the accounts meet the required standards |
Small Company vs Micro-Entity: Which One Applies to Your Healthcare Practice?
This matters because it determines how much detail you need to include in your publicly filed accounts and what exemptions you can take advantage of.
Micro-Entity: You qualify if you meet at least two of the following:
- Turnover of £1 million or less
- Balance sheet total of £500,000 or less
- 10 or fewer employees
If you qualify as a micro-entity, your publicly filed accounts at Companies House are very minimal. While you must still prepare a profit and loss account for HMRC and your shareholders, you do not need to include it in your public filing at Companies House. This allows you to keep your turnover and profit figures private.
Small Company: You qualify if you meet at least two of the following:
- Turnover of £15 million or less
- Balance sheet total of £7.5 million or less
- 50 or fewer employees
Small companies can file ‘filleted’ or abridged accounts at Companies House but must submit full accounts to HMRC using commercial software as part of their Company Tax Return.
Most solo GP practices, small dental practices, single-location care homes, and private clinics will fall into one of these two categories.
Step-by-Step Process for Preparing Company Accounts for Medical Firms
Annual accounts preparation is a journey that starts with keeping decent records throughout the year and ends with a set of accurate, compliant documents. Here’s how the statutory annual accounts preparation actually looks:
Step 1: Gather All Your Financial Records
First, you need to round up the paperwork for annual accounts preparation. This means grabbing every bank statement from the relevant period. This includes all those NHS remittance advice and any private patient invoices or sessional fees you’ve collected. Don’t forget the receipts for medical supplies, equipment, and staff costs, plus any loan or finance agreements. The tidier you keep these records during the year, the faster (and cheaper) this whole annual accounts for limited company becomes.
Step 2: Reconcile Your Bank Accounts
Now you need to make sure that every single transaction on your bank statement has a matching entry in your bookkeeping. If you find a random payment that doesn’t have a home, you need to figure it out before you can move on with annual accounts preparation.
Step 3: Account for Accruals and Prepayments
Remember you need your accounts to reflect income and costs for when the work actually happened, not just when the cash was received. If you paid for a year of professional indemnity insurance in February, only a bit of that belongs in this year’s accounts. And the rest is a “prepayment” for next year. This is an important step in annual accounts preparation.
Step 4: Depreciate Your Assets
Things like dental chairs, X-ray machines, and even your office computers lose value as they get older. You can’t just write off the whole cost the day you buy them. Instead, you “depreciate” them. This means you spread that cost over a few years in a consistent way so your profit accurately reflects.
Step 5: Prepare the Tax Computation
Once the accounts are drafted, you need to calculate what you owe HMRC. Your accountant will take your profit and tweak it to fit HMRC’s specific rules. For example, they’ll swap out that depreciation you just calculated for “Capital Allowances,” which is the official tax version of writing off equipment.
Step 6: Draft the Statutory Accounts
This is the formal stage of annual accounts preparation, where everything is compiled into the official balance sheet and profit and loss account. Most small medical firms use simplified rules (like FRS 102 or 105), which keeps the paperwork a bit thinner. It’s basically the “official” version of your financial story for the year.
Step 7: File With Companies House and HMRC
This is the finish line of annual accounts preparation. You need to submit these to two different places. Companies House gets a version of the accounts, while HMRC gets the full set plus your actual tax return. Once your accounts are submitted via compliant accounting software and the digital filings are accepted by both gateways, you can finally tick it off your list.
Key Deadlines for Annual Accounts Filing in 2026/27
Missing a deadline is the easiest way to lose money to HMRC or Companies House penalties. For most annual accounts for limited company, you have nine months after your financial year ends to file your accounts.
| Document Type | Deadline | Who it goes to |
| Annual Accounts | 9 months after year-end | Companies House |
| Company Tax Return (CT600) | 12 months after year-end | HMRC |
| Corporation Tax Payment | 9 months and 1 day after year-end | HMRC |
Early annual accounts filing is always better. It gives you a clear idea of your tax bill months before you actually have to pay it. This is also important for managing the cash flow of a busy clinic or pharmacy.
What Happens if I File My Annual Accounts Late?
There are two separate, distinct sets of penalties for filing late. Because you have to file with both Companies House and HMRC, you can actually be fined by both at the same time.
1. Companies House Penalties (For your Annual Accounts)
Companies House will issue automatic late filing penalties the moment your deadline passes. For a private limited company, the costs are:
| How Late Are You? | Penalty |
| Up to 1 month | £150 |
| 1 to 3 months | £375 |
| 3 to 6 months | £750 |
| More than 6 months | £1,500 |
Note: These penalties are doubled if your accounts are filed late in two successive financial years.
2. HMRC Penalties (For your Company Tax Return)
HMRC has its own separate penalty system for late Company Tax Returns (CT600). As of 1 April 2026, these fixed penalties have doubled to keep up with inflation:
| How Late Are You? | Penalty |
| 1 day late | You will receive an immediate £200 penalty. |
| 3 months late | Another £200 is added (totalling £400). |
| 6 months late | HMRC will estimate your tax bill and add a penalty of 10% of the unpaid tax. |
| 12 months late | Another 10% penalty is added to any unpaid tax. |
Beyond the financial cost, persistent late filing can affect your company’s credit rating. It can also raise concerns during due diligence if you ever look to sell the business or bring in new investors.
Therefore, it’s recommended to set a reminder at least three months before the deadline.
Common Mistakes Healthcare Limited Companies Make With Their Accounts
During annual accounts preparation, these mistakes often come up. And they can lead to tax overpayments, penalties, or even HMRC enquiries.
- Mixing personal and business expenses. This is especially common among sole director healthcare companies where the director is also the main clinician. Personal costs that accidentally find their way into the company accounts are a problem.
- Not claiming all allowable expenses. Healthcare business owners regularly miss legitimate deductions. CPD courses, professional subscriptions (GMC, GDC, NMC), clinical equipment, protective clothing, software, and home office use, where applicable, can all be legitimate deductions depending on your circumstances.
- Incorrect treatment of NHS pension contributions. This is a common issue for GPs. If you are in the NHS pension scheme as a limited company director, the treatment of those contributions in your accounts and tax return needs to be handled carefully.
- Forgetting about dividend planning. Many healthcare company directors take a combination of salary and dividends. This is perfectly legal but needs to be documented properly, with formal dividend minutes and vouchers for every dividend payment.
- Ignoring mandatory ID verification. As of 2026, all PSCs and directors must verify their identity with Companies House. If you fail to complete this during the current transitional period (ending November 2026), it can lead to significant penalties.
Is Annual Accounts Preparation Necessary for Dormant Companies?
Even if you have taken a break from clinical work and your company hasn’t traded at all, you still have to file. You can usually file “dormant accounts,” which are much simpler, but you cannot just ignore the filing date. HMRC and Companies House still need to know that the company is still active in their records.
What Is the Difference Between Annual Accounts and a Tax Return?
Your annual accounts preparation is a set of financial statements that show how your company performed over the year. They follow accounting standards and as of 1 April 2026, your annual accounts and tax return must be filed as two separate digital submissions using commercial software. Your Corporation Tax Return, known as a CT600, is a separate document that calculates how much Corporation Tax your company owes.
The two documents are related because the tax return starts from the profit in your accounts, but they are distinct filings. Your accountant will normally prepare both at the same time as part of the year-end process.

Do I Need to Keep Records and for How Long?
Yes. HMRC requires limited companies to keep accounting records for at least 6 years from the end of the accounting period they relate to. This includes invoices, bank statements, payroll records, contracts, and any other documents that support your accounts.
If HMRC opens an enquiry, they can request records going back up to 20 years in cases of suspected fraud. For healthcare businesses, good record-keeping is also important from a regulatory perspective, as CQC inspections can sometimes touch on financial sustainability.
What Is a Director’s Loan Account and Why Does It Matter?
A director’s loan account tracks money you take from or put into your company outside of salary and dividends. If you take money from the company informally, it creates a loan from the company to you. If this loan exceeds £10,000 at any point during the year, you may need to pay a benefit in kind tax charge.
If the loan is still outstanding nine months after your year end, the company also has to pay a temporary Corporation Tax charge. It is currently 35.75% for loans made from 6 April 2026, until it is repaid. Keeping your director’s loan account in order and fully reconciled is an important part of annual accounts preparation for healthcare company directors.
What Is the Corporation Tax Rate for My Healthcare Company?
The current main rate of Corporation Tax is 25% for companies with profits above £250,000. If your company’s profits are £50,000 or below, the small profits rate of 19% applies. Between these thresholds, marginal relief gradually increases the effective rate. For example, a company with annual profits of £100,000 would pay an effective rate between 19% and 25%, calculated using the marginal relief formula. Many small healthcare companies fall within this marginal relief band, which makes year-end profit planning important.
Can You Prepare Your Own Annual Accounts?
Technically, yes. There is no legal requirement for a limited company to use an accountant for its annual accounts preparation. But for most healthcare professionals, it is not the best use of their time, and the risk of getting something wrong is real.
The annual accounts preparation process involves understanding UK GAAP accounting standards, Corporation Tax rules, Companies House filing requirements, and the mandatory use of commercial software for HMRC filings. It also involves a range of technical judgements about recognition, measurement, and disclosure. For a GP or dentist running a busy practice, spending 40 to 80 hours a year on this is not realistic.
More importantly, mistakes can cost more than the accountant’s fee. A missed capital allowance claim, an incorrectly categorised expense, or a late filing penalty can add up quickly.
Do Healthcare Limited Companies Need an Accountant?
You can do annual accounts preparation and file your own accounts. However, most healthcare professionals prefer working with accountants who specialise in the medical sector.
Because statutory annual accounts preparation involves adjustments (like accruals, depreciation, and provisions), professional accountants reduce risk and save you time. This lets you focus on patients, not paperwork.
The Bottom Line
If annual accounts preparation is done right, it keeps you compliant and helps you understand your business. If done poorly or left until the last minute, it costs money and can create problems with HMRC or Companies House that take time to sort out.
Therefore, if you are running a healthcare limited company in the UK, working with an accountant who understands the healthcare sector specifically is worth the investment.
