Should I register as a sole trader or a limited company?

Sole trader: simpler, personally on the hook

As a sole trader you are the business. Profits are yours, losses are yours, and creditors can pursue personal assets if things go wrong. Self Assessment and, if needed, VAT are the core filings.

That simplicity is valuable at the start. One UTR, one return, drawings from the same account if you must. It is also why a tradesperson with site risk, or a consultant with a large contract, often outgrows it.

Limited company: extra law, limited liability

A company is a separate legal person. It owns the contracts, pays Corporation Tax on its profits, and files accounts at Companies House. You take money as salary, dividends or both. Directors’ duties apply even if you own 100 percent.

Limited liability is real but not magic. Banks still ask for personal guarantees. Wrongful trading, unpaid PAYE and some taxes can still reach directors. Incorporation is a governance decision as well as a tax model.

• Compare take-home after Corporation Tax, PAYE and dividend tax — not turnover.
• Budget for accounts, Confirmation Statement and a payroll even for one director.
• Do not fold a risky trade into a company and strip it of assets the same week.

Tax is only one column

At modest profits a sole trader can still take home more after National Insurance than a company once you pay for accounts and payroll. At higher profits, retained cash, research reliefs or bringing in a shareholder can tip the other way. The numbers need a spreadsheet for your case.

IR35 and off-payroll working can also make a company less attractive for some contractors. Solaratax will model both structures and the cost of moving from one to the other. Book a conversation before you buy an off-the-shelf company.

Questions we are asked

Can I start as a sole trader and incorporate later?

Yes. You can transfer the trade into a company. There are tax and VAT issues on the transfer, including possible capital gains and VAT on assets. Plan the date.

Does a company look more professional?

Sometimes. Customers and lenders do notice ‘Ltd’. That is not a reason to ignore the filing burden or a personal guarantee sitting in the pack.

Is an LLP the middle option?

It can be for professional firms. See LLP versus limited company.
