If you run a small business in the UK, you've probably wondered whether you should file micro entity accounts or small company accounts with Companies House. Here's the simple answer: micro entity accounts are the most basic form of financial reporting available to the smallest UK companies, showing only essential balance sheet information, while small company accounts include more detail, such as a profit and loss statement. The main difference comes down to company size, how much information you're required to disclose, and what makes sense for your business.
Let me walk you through everything you need to know to make the right choice for your company.

From Paperwork to Peace of Mind – Trust Micro Entity Accounts.
What exactly are Micro Entity Accounts?
Micro entity accounts are simplified financial statements designed for the UK's smallest limited companies. Think of them as the "bare minimum" reporting option that Companies House allows.
When you file micro entity accounts, you only need to submit an abridged balance sheet. This shows what your company owns (assets) and owes (liabilities) on a specific date, usually your financial year-end. You don't have to include a profit and loss account, directors' report, or detailed notes to the accounts in your public filing.
This simplified approach was introduced in December 2013 to reduce the administrative burden on Britain's smallest businesses. It's based on EU accounting rules and makes financial reporting much less time-consuming if you qualify.
What are small company accounts?
Small company accounts are a step up from micro entity accounts in terms of detail and disclosure.
When you file small company accounts, you must include a balance sheet and profit and loss account. You'll also need to add notes to the accounts explaining various figures, though you can still use certain exemptions that aren't available to medium or large companies.
Small company accounts show more about your business performance. Anyone searching for your company at Companies House can see your turnover, cost of sales, and profit figures, giving them a clearer picture of how your business is doing financially.
Many accountants actually recommend small company accounts for businesses that want to demonstrate credibility to potential lenders, suppliers, or partners.
What is the difference between a micro entity and a small entity?
The difference comes down to three specific thresholds set by Companies House. Your company qualifies as a micro entity if it meets at least two of these criteria:
- Turnover of £1M or less
- Balance sheet total of £500,000 or less
- 10 employees or fewer
For a small company status, the thresholds are considerably higher. You qualify as a small company if you meet at least two of these:
- Turnover of £15 million or less
- Balance sheet total of £7.5 million or less
- 50 employees or fewer
So every micro entity is technically a small company, but not every small company is a micro entity. It's like saying every square is a rectangle, but not every rectangle is a square.
Here's what this means in practice: if your limited company has a turnover of £800,000, you're too large to file micro entity accounts, but you still qualify as a small company and can use those filing options instead.
Will HMRC accept micro entity accounts?
Yes, but here's something important to understand: HMRC and Companies House are two separate organisations with different requirements.
Companies House accepts micro entity accounts for your annual filing obligation. This is the public record of your company's financial position.
However, HMRC requires full statutory accounts when you file your Corporation Tax return, regardless of what you've filed with Companies House. So even if you submit micro entity accounts to Companies House, you still need to prepare and submit full accounts to HMRC that include your profit and loss account.
This catches many business owners off guard. You might file simplified accounts publicly, but still need detailed accounts for your tax return. Most accounting software and accountants handle both versions for you, but it's worth knowing you can't just prepare one set and be done.
What's the difference between micro entity accounts and full accounts?
Full accounts (also called statutory accounts) include everything about your company's financial performance and position.
A complete set of full accounts typically includes:
- Balance sheet showing assets and liabilities
- Profit and loss account showing income and expenses
- Directors' report explaining business activities and performance
- Detailed notes to the accounts
- Auditor's report (if your company requires an audit)
Micro entity accounts strip this right back. You only file a very basic balance sheet with Companies House. No profit and loss, no directors' report, minimal notes.
The advantage of micro entity accounts is privacy and simplicity. Your competitors, customers, and the general public can't see how much profit you're making or what your turnover is. They can only see a snapshot of your assets and liabilities.
The disadvantage is that some banks, suppliers, or potential business partners might ask you to provide more detailed accounts anyway. They want to see the full picture before extending credit or entering into agreements with your company.
What qualifies as a microbusiness?
In accounting terms, we've covered the thresholds above, but let's look at this from a practical angle.
You likely qualify as a microbusiness if you:
- Run a limited company with just yourself or a handful of employees
- Have annual sales under £1M
- Don't own property or significant assets through the company
- Keep things relatively straightforward financially
Common examples include freelance consultants who've set up a limited company, small trades businesses, independent shops, or local service providers.
However, even if you technically qualify based on the numbers, you're not required to file micro entity accounts. You can choose to file small company accounts instead if you prefer the additional transparency or if stakeholders expect it.
Which type of accounts should you file for your business?
This decision isn't just about what you're allowed to do; it's about what makes sense for your situation.
Choose micro entity accounts if you:
- Want maximum privacy for your business finances
- Run a very straightforward limited company
- Don't need to demonstrate financial performance to banks or investors
- Want to minimise time spent on public filing
Choose small company accounts if you:
- Want to show credibility to lenders or suppliers
- Have shareholders or partners who expect more transparency
- Feel that the additional detail better represents your business
- Work with an accountant who recommends this approach
Remember, you prepare full accounts for HMRC either way. This choice is purely about what gets filed publicly at Companies House.
Can you switch between micro entity and small company accounts?
Yes, absolutely. You can change your approach each year based on your current circumstances.
Perhaps in your first year of trading, you filed micro entity accounts for privacy. Now you're applying for business finance, and the bank wants to see more detail, so you switch to small company accounts the following year. That's perfectly acceptable.
Just make sure you still meet the qualifying thresholds. If your business grows beyond the micro entity limits, you'll need to file small company accounts anyway.
Your accountant should review this decision with you each year during your year-end process. It's worth having a conversation about what makes sense given where your business is and where you want it to go.
Common mistakes to avoid when filing your accounts
Many business owners trip up on a few key points:
Filing the wrong accounts with the wrong organisation. Companies House gets your statutory filing (micro entity or small company accounts). HMRC gets your full accounts with your Corporation Tax return. Don't send your micro entity accounts to HMRC and wonder why they're asking for more information.
Missing the deadline. You must file accounts with Companies House within 9 months of your financial year-end. HMRC gives you 12 months for your Corporation Tax return. Missing either deadline results in automatic penalties that start at £150 and increase the longer you delay.
Assuming you automatically qualify every year. Your business circumstances change. Maybe you hired more staff or turnover increased. Check the thresholds each year before deciding which accounts to file.
Not keeping proper records. Whether you file micro entity or small company accounts, you need to maintain proper books and records. HMRC can request these during an enquiry, and you're legally required to keep them for at least six years.
Do you need an accountant to prepare your accounts?
You're not legally required to use an accountant, but here's the reality most business owners face.
Preparing accounts that comply with UK accounting standards, Companies House requirements, and HMRC expectations involves understanding complex regulations. The accounting standards for micro entities (FRS 105) and small companies (FRS 102 Section 1A) contain specific rules about how to present financial information.
Getting it wrong can result in rejected filings, penalties, or HMRC enquiries that cost far more than an accountant would have charged in the first place.
Most business owners find that an accountant pays for themselves through:
- Ensuring compliance and avoiding penalties
- Identifying tax reliefs and allowances you might miss
- Preparing both versions of accounts (public filing and HMRC submission)
- Providing year-round advice on business decisions
- Giving you peace of mind that everything's done correctly
If your business is very simple and you're comfortable with accounting software, you might manage yourself. But as soon as things get slightly complicated—multiple income streams, assets, employees, VAT—professional help usually makes sense.
What happens if you file the wrong type of accounts?
Companies House will reject accounts that don't meet their requirements. You'll receive a notice explaining why and giving you time to correct and resubmit.
The problem is that this eats into your filing deadline. If the rejection and correction process pushes you past your deadline, you'll face late filing penalties even though you tried to file on time.
If you file micro entity accounts but don't actually qualify (perhaps your turnover exceeded the threshold), Companies House may accept them initially but could raise questions later. HMRC might also notice the discrepancy when they see your full accounts with the Corporation Tax return.
The safest approach is to honestly assess your company's size each year and choose the appropriate filing option. When in doubt, ask your accountant or contact Companies House directly for guidance.
