Sole Trader vs Limited Company: What Changes for Your Accounts?

Choosing between trading as a sole trader and setting up a limited company is one of the first big decisions most business owners make, and revisiting it later is common too. The two structures are taxed differently and, just as importantly, they require different accounting records. Understanding what actually changes helps you decide with your eyes open, rather than guessing.

Who Owns the Money

As a sole trader, there is no legal separation between you and your business — everything the business earns is yours, and everything it owes is yours too. A limited company is a separate legal entity. It has its own bank account, its own set of accounts, and its own tax return. Money the company makes belongs to the company, not to you personally, until you draw it out as salary, dividends, or another formal route.

This distinction is the root of almost every other difference on this list.

What You Need to Record

Sole traders need to keep records of income and expenses to complete a Self Assessment tax return. It's relatively light-touch, though still a legal requirement to retain records for a set number of years.

A limited company has considerably more to keep on top of:

• Statutory annual accounts filed with Companies House
• A Corporation Tax return filed with HMRC
• Payroll records if you or anyone else is paid a salary through the company
• Dividend records, including board minutes and vouchers, if you pay yourself dividends
• A director's loan account if money moves between you and the company outside salary and dividends

This is one of the main reasons limited companies tend to need more structured bookkeeping than sole traders — there's simply more to track accurately.

How You're Taxed

A sole trader pays Income Tax and National Insurance on all their business profit, whether or not they take the money out of the business. A limited company pays Corporation Tax on its profit, and then you personally pay tax again on whatever you draw out as salary or dividends — but not on profit left in the company.

The rates, thresholds and allowances involved change periodically, so rather than quote figures here, it's worth checking the current rules on gov.uk before you decide. This isn't personalised tax advice — the right structure depends on your profit level, how much you need to draw out personally, and your plans for the business, so talk it through with an accountant about your specific situation.

What Happens to Your Reporting

Because a limited company is a separate entity, its accounts need to stand on their own — a balance sheet, a profit and loss account, and notes that explain what's in them. That's a more formal exercise than most sole traders go through, and it's also where our services around monthly management accounts tend to add the most value, giving directors a clear read on the business between the once-a-year statutory filing.

Making the Switch

Moving from sole trader to limited company partway through the year means splitting your records at the changeover date, registering the new company, and often opening a new business bank account. It's straightforward with the right support, but it does need planning — timing the switch around your year end, VAT registration and any contracts held in your own name all matter.
