Accountant For A Limited Company

Your company year end accounts explained

A UK limited company's first year-end requires filing a CT600 corporation tax return with HMRC and statutory accounts with Companies House, plus an annual confirmation statement. Late filing triggers HMRC penalties starting at £100 and Companies House penalties from £150 to £1,500 for private companies, with penalties doubled if filings are late in two successive years.

Key takeaways

  • A UK limited company's first year-end requires three core filings: a CT600 corporation tax return with HMRC, statutory accounts with Companies House, and an annual confirmation statement.
  • Private company accounts are due at Companies House 9 months after the financial year end, and the corporation tax return is due 12 months after the accounting period ends.
  • HMRC charges £100 after a CT600 is one day late and another £100 at three months late; these rise to £500 each if the return is late three years in a row.
  • Companies House late-filing penalties for private companies are £150, £375, £750, and £1,500 across the 1, 3, 6, and 6+ month brackets, and all penalties are doubled if accounts are late in two consecutive years.
  • Limited companies must keep accounting records for at least six years from the end of the financial year they relate to, including invoices, receipts, bank statements, payroll, and VAT records.

Company Year End Accounts Overview

<p>Approaching a company's first year-end can feel incredibly stressful, as there will be a lot of paperwork you need to file at this time.<br></p><p>In this article we provide you with a simple list of what you will need to do, along with a few tips to make the whole process easier for you. We finish with the penalties and deadlines for late filing.</p>

Filing Company Year End Accounts with HMRC

You will need to file your company tax return, also known as the CT600 form, online.

To do this you will need your company accounts and your corporation tax calculation.

You will also need to file a director's report, unless your company is a micro-entity. Depending on the size of your company, you might also need to include an auditor's report.

Filing Company Accounts with Companies House

You will also need to file a copy of your accounts with Companies House. There is an option on the HMRC website for joint filing.

Companies House also require you to complete an annual Confirmation Statement, detailing who owns your company and how many shares it has. This is easy to do online—provided you have not changed the way your company is structured.

Year End Accounts & VAT (HMRC)

If your company is VAT-registered, your VAT return will likely be due around the same time as your company year-end. 

Do note that this doesn't apply if you pay your VAT monthly or quarterly, as the deadline will then fall one month and seven days after the end of each VAT period.

4 tips for making filing less stressful

Set up email reminders

Sign up for Gov.uk's email reminder service. This ensures that you will get a timely reminder a few weeks before your accounts and confirmation statement are due for filing. 

You might remember it all now, but it is very easy to forget such things with the hectic pace of running a new business.

Be rigorous with your expenses

Ensure you record all your expenses, and keep a copy of all your invoices and receipts. This is especially important in the first year when you will incur all your start-up costs.

According to HMRC, expenses must be incurred "wholly and exclusively" for running your business to be allowable for tax purposes.

If you're unsure about which expenses you can or can't claim, a qualified accountant can help you out.

Your accountant will also be able to provide personalised advice, such as making recommendations for expenditure that you can bring forward to reduce your total profit.

Plan ahead for the upcoming year

It's important that you set aside time to map out financial plans for the upcoming year. Book a meeting with your accountant, so you can review the past year and identify any areas you can improve on. 

You may want to discuss how you can cut down on your tax bill, manage your cash flow more efficiently or assess if the capabilities of your current accounting software is aligned with your business needs and future goals. 

Ensure that you've kept proper records

Before you file your company year-end documents or returns, check that you've kept a copy of documents that are required to back up your calculations. 

These include receipts, invoices, bank statements, records of income and more. Your records must be kept for six years from the end of the last financial year they pertain to.

Company Year End Accounts Filing Deadline

The best way to avoid these it to be aware of your responsibilities and keep good records from the start. The worst way is to leave everything until the last month before it's due.

Frequently asked questions

What do I need to file at my company year-end?

A UK limited company has three year-end filings. The CT600 corporation tax return goes to HMRC with supporting accounts and the tax calculation. A copy of the statutory accounts goes to Companies House; HMRC's online service offers joint filing with Companies House to submit both at once. An annual confirmation statement is also filed at Companies House to confirm directors, shareholders, SIC codes, and registered office details.

When are company year-end accounts due?

Statutory accounts must reach Companies House within 9 months of a private company's financial year end, or 6 months for a public company. The first set of accounts is due 21 months after incorporation or 3 months after the first accounting reference date, whichever is later. The corporation tax return is due 12 months after the accounting period, and any corporation tax owed is payable 9 months and 1 day after the period ends.

What happens if I file my company accounts late?

HMRC issues an automatic £100 penalty for a late corporation tax return, another £100 at three months late, and adds a tax-based penalty at six and twelve months. The £100 penalties rise to £500 each if returns are late three years running. Companies House fines private companies £150, £375, £750, or £1,500 depending on how late the accounts are, with all penalties doubled if accounts are late in two consecutive years.

Do I need to file a VAT return with my year-end accounts?

If the company is VAT-registered, a VAT return will usually be due close to the year end but is filed on its own VAT schedule, not with the company accounts. Most VAT-registered businesses file quarterly, with the return and any VAT payment due one month and seven days after the end of each VAT period. Annual accounting scheme participants file one return per year instead, with monthly or quarterly instalments.

What records do I need to keep for my year-end accounts?

UK limited companies must keep records for at least six years from the end of the financial year they relate to. This includes sales invoices, purchase invoices, receipts, bank statements, payroll records if staff are employed, and VAT records if registered. HMRC can request these during a compliance check, and Companies House can require directors to produce them. Records tied to ongoing contracts should be kept until that contract closes.

Can I reduce my year-end tax bill by claiming the right expenses?

Yes. Any expense incurred wholly and exclusively for business purposes can usually be deducted against corporation tax. Common claims include office costs, travel and subsistence, professional fees, software subscriptions, employer pension contributions, and the Annual Investment Allowance on qualifying capital equipment. Reviewing expenses with an accountant before the year end often identifies legitimate costs that would otherwise be missed, and can include bringing forward planned expenditure to the current year.

Do I need an accountant to file my company year-end accounts?

Legally no, a director can prepare and file company accounts themselves. In practice an accountant is valuable for trading companies because statutory accounts must follow UK accounting standards, the CT600 requires corporation tax calculations, and disclosures are needed for directors' loans, dividends, and related-party transactions. An accountant also reduces the risk of late-filing penalties and HMRC enquiries, and can offer tax planning advice that often saves more than their fee.
