Yes, you can do your own accounts for a UK limited company. There is no general rule that says that you must hire an accountant. As a director, you can keep the company’s accounting records, prepare the annual accounts, and calculate Corporation Tax. And yes, you can also file the required returns yourself.
However, you now need commercial accounting software to file, depending on the specific type of filing and entity. Also, the accounts still have to follow proper accounting standards and be accurate.
For a lot of small companies, it’s doable.
For others, one mistake can cost more than an accountant’s fee would have.
Right? So, let’s get into the actual details!
Is It Legally Allowed to Do Your Own Accounts For a Limited Company?
Yes, it is legally allowed. You absolutely can do your own accounts for a limited company. Company directors in the UK hold the legal responsibility to maintain accurate financial records. You can log expenses, track income, and file reports yourself.
Plenty of business owners do almost everything on their own at the start. This is because in the first year of trading, saving money feels like a top priority. So that makes total sense.
But remember that doing your accounts yourself means you also take on all the legal liability. This means that if you miss a tax rule or file late, HMRC will send penalty letters to you, not your software company.
Doing Your Own Accounts: What Do Companies House and HMRC Expect?
Running a limited company means that every year you are legally required to send specific documents to two different government departments.
Yes, you need to deal with two separate UK bodies:
- To Companies House: You must send your annual statutory accounts within 9 months of your financial year-end. You also need to file a Confirmation Statement once a year to confirm your company details are up to date.
- To HMRC: You need to file a Company Tax Return (Form CT600). This calculates how much Corporation Tax your business owes based on your profits. Any tax owed must be paid earlier, within 9 months and 1 day after your accounting period ends.
For the 2026/27 tax year, the main Corporation Tax rate is 25% for companies with profits over £250,000. If your profits are £50,000 or less, you need to pay the small profits rate of 19%. Anything in between gets a marginal relief rate.
What Does Managing Your Limited Company Accounts Actually Involve?
Remember that “Doing your accounts” is not a one-and-done job for the end of the year. It is a chore that basically stays on your plate every single month. Yes!
In practice, if you’re taking this on yourself, first you have the day-to-day administrative tasks to handle throughout the year:
- Continuous bookkeeping: Tracking every sale, purchase, and receipt as it happens, rather than in one big panic at the end of the year.
- Bank reconciliation: Matching your business bank statements against your records to ensure your numbers actually check out.
- Regular VAT and payroll: Calculating VAT returns on your required schedule and running monthly payroll (including PAYE and pensions) if you pay yourself or staff.
- Record retention: Organising and keeping all files safe for at least six years in case HMRC ever asks questions.
All of that daily tracking eventually builds up to your annual year-end filings. This is where you package everything into formal statutory accounts using approved software. Your final year-end package sent to Companies House and HMRC must legally include:
- A balance sheet: Showing exactly what your company owns and owes on the final day of your financial year.
- A profit and loss account: Summarising your total business income and running costs over the 12-month period.
- Notes to the accounts: Giving the government a breakdown of the background details behind your specific figures.
- A Company Tax Return (CT600): The official tax form required by HMRC to calculate your final Corporation Tax bill.
Some of these tasks become routine once you start doing them and get used to them. But some of them really need a genuine understanding of accounting rules to get right.
A single mistake here can easily lead to an automated penalty or an overpaid tax bill.
Is It Actually Easy to Do Accounts For A Limited Company Yourself?
Honestly? It depends on your business size and your patience. If you only have a few transactions a month, then yes, doing your own accounts is completely doable.
Here is what your workload looks like if you take the DIY route versus hiring a team:
| Task | Doing It Yourself (DIY) | Using a Firm Like Accotax |
| Daily Bookkeeping | You sort invoices and match bank statements. | We can handle it or check your work. |
| Tax Software Cost | You pay for monthly software subscriptions. | Often included in our fixed-price packages. |
| Year-End Filing | You map accounts and fill out Form CT600. | Qualified pros submit it flawlessly for you. |
| Tax Planning | You must research tax-saving strategies alone. | We proactively find ways to lower your bill. |
While saving money on fees feels great early on, many owners find that keeping up with shifting tax laws takes hours away from actual client work.
What Are the Risks of Doing Your Own Accounts for a Limited Company?
The government does not give you a pass just because you are new to business. If you make a mistake, you have to pay for it.
First, late filing penalties are automatic. If you miss your Companies House deadline by even one day, it is an instant £150 fine. If you leave it over six months, that fine increases significantly.
You can check out the full breakdown of Companies House late filing penalties.
Second, you might actually lose money by trying to save on accountant fees. Do you know exactly which business expenses are legally allowed this year? If not, missing out on valid tax allowances means you end up paying a much higher Corporation Tax bill than necessary.
Is Doing Your Own Limited Company Accounts Cheaper?
Potentially, yes. It is cheaper. You save the professional fee if you are handling the bookkeeping, accounts, and tax filing yourself.
But there is also another side to the calculation.
Your time has a value.
If you spend 15 hours learning accounting rules and fixing bookkeeping issues, the “free” option may not actually feel that free.
There is also the cost of mistakes.
A small error in an expense category may be easy to fix. But errors involving dividends, directors’ loans, VAT, payroll or Corporation Tax can be more complicated.
For some businesses, DIY accounting makes perfect sense. For others, paying an accountant is simply a more efficient use of the director’s time.
When Does Hiring an Accountant Make Sense?
There’s no single point where DIY accounting stops working, and you suddenly need an accountant. It is actually more of a gradual thing.
Here is when you should seriously consider hiring an accountant for your limited company accounts:
- You register for VAT: The paperwork gets brutal quickly, and mistakes are expensive. Also, because now you are legally required by HMRC to use Making Tax Digital (MTD) compatible software to file.
- You hire your first employee: Dealing with payroll, pensions, and HMRC tax codes is something you don’t want to deal with yourself.
- Your transactions explode: If you are sorting through dozens of sales or invoices a week, it is time to automate.
- You hate spreadsheets: If bookkeeping is consuming your weekends, your time is better spent growing the business.
- You want to save on taxes: A good accountant does not just fill out forms. They actively find legal ways to lower your Corporation Tax bill. They can claim expenses you probably do not even know exist.
You might also use an accountant simply because you do not want to spend your evenings doing bookkeeping.
That’s a perfectly reasonable reason.
