Going limited,
in the right order.

To change from sole trader to limited company: incorporate at Companies House, open a bank account in the company's name, register for corporation tax, sort VAT, move contracts and insurance across, transfer assets at market value, then tell HMRC the sole trade has ceased.

General guidance for UK businesses, not tax or legal advice. Asset transfers and VAT history have consequences specific to your situation — take advice before you file.

What order should you do it in?

  1. 1

    Get the numbers checked first

    Have an accountant run your actual profits through both structures before anything is filed. Incorporating for a saving that turns out not to exist is an expensive way to acquire a filing calendar.

  2. 2

    Incorporate at Companies House

    Choose the company name, appoint the director or directors, issue the shares and give a registered office address. It is an online filing with a small fee and usually completes within a day. A service address keeps your home address off the public register.

  3. 3

    Open a bank account in the company's name

    This is not optional housekeeping. The company's money is legally not yours, and mixing the two is the most common mess an accountant has to untangle after incorporation.

  4. 4

    Register the company for corporation tax

    Do this with HMRC within three months of starting to trade through the company. You will also need PAYE if you are taking a salary, and to consider VAT registration.

  5. 5

    Deal with VAT

    The company is a new legal person, so it needs its own VAT registration. You can apply to transfer your existing VAT number using form VAT68 — which keeps the number but also transfers the registration's history, so take advice on whether you want that.

  6. 6

    Move contracts, insurance and suppliers across

    Customer contracts, insurance, leases, trade accounts, domain and payment processor all need to name the company rather than you. Insurance in particular: a policy in your own name may not cover work done by the company.

  7. 7

    Transfer the business assets to the company

    Tools, vehicles, equipment and any goodwill pass to the company at market value, which has capital gains and capital allowance consequences on both sides. Get this valued and documented rather than assumed.

  8. 8

    Tell HMRC the sole trade has stopped

    Your sole trader business ceases on a particular date. You still file a final Self Assessment return covering trading up to that date, so keep those records exactly as before.

What happens to your UTR?

Your personal UTR stays yours. It is attached to you, not to the business, and you keep using it for Self Assessment for as long as you have to file one — which, as a director drawing dividends, will usually be every year.

The company gets its own separate UTR for corporation tax, issued after incorporation and sent to the registered office. Two numbers, two regimes, no overlap.

What actually transfers, and what does not?

What happens
Your personal UTRStays with you — the company gets its own for corporation tax
VAT registrationThe company needs its own; the existing number can be transferred via VAT68, along with its history
Bank accountDoes not transfer. The company opens its own
Business assetsTransferred to the company at market value, with tax consequences both sides
Customer contractsReassigned to the company — not automatic, and some clients will re-paper
InsuranceNew policy in the company's name; check cover does not lapse in the gap
Trading nameCan be used by the company, and incorporation protects it more firmly
EmployeesTransfer with continuous service preserved — TUPE may apply
Business debtsStay personal unless the lender agrees to novate them to the company

What new obligations start on day one?

  • Annual accounts filed at Companies House, with a deadline tied to the company's year end.
  • A corporation tax return, and corporation tax paid within nine months and a day of the year end.
  • A confirmation statement every year, even when nothing has changed.
  • Real Time Information payroll submissions each time you run a salary through PAYE.
  • Your own Self Assessment return, now covering salary and dividends.
  • A statutory register of members, directors and people with significant control.

What do people get wrong?

The one that causes real damage is treating the company account as a personal one. Money taken out that is not salary, dividend or expense reimbursement is a director's loan, and an overdrawn director's loan account at year end carries its own tax charge. Entirely avoidable, and entirely common.

The second is declaring dividends without the profit to support them. Dividends can only be paid out of distributable profits, so paying one the company has not earned makes it unlawful and reclassifiable. This is where keeping the books current stops being administration and starts being protection.

The third is quiet: forgetting the filing dates. Companies House penalties escalate, and they arrive whether or not the company traded.

How does Bizzle handle the change?

The ledger carries across, so incorporation is a new entity rather than a new start — the sole trade closes cleanly with its final figures intact, and the company opens with the assets it actually received.

Company money and your money stay separated by the structure rather than by your memory: drawings, salary and dividends are recorded as what they are, so nothing quietly becomes a director's loan by accident.

Your accountant keeps their free login throughout, which matters most in the year you incorporate — the year with two sets of figures and the most ways to get it wrong.

COMMON QUESTIONS

Questions people ask.

How long does it take to change from sole trader to limited company?

Incorporation itself is usually same-day online. The rest — bank account, VAT, contracts, insurance, asset transfer — realistically takes a few weeks, and the bank account is normally the slowest part. Start that application early rather than last.

Do I need to tell HMRC I have stopped being a sole trader?

Yes. You tell HMRC the sole trade has ceased and file a final Self Assessment return covering trading up to that date. You do not come out of Self Assessment altogether if you still need to file, which as a director taking dividends you generally will.

Can I keep my VAT number?

You can apply to transfer it to the company using form VAT68. It keeps continuity for customers, but it also transfers the registration's history and any liabilities with it, so it is worth asking your accountant whether a clean registration suits you better.

What happens to my business bank account?

It does not transfer. The company is a different legal person and needs its own account. Keep the old one open long enough to settle anything outstanding from the sole trade, then close it.

Can I move my customers over automatically?

No. Contracts are with you personally, so they have to be assigned or re-signed with the company. Most customers treat this as a formality; larger ones may want new paperwork, supplier onboarding, or evidence of the company's insurance.

Is it worth incorporating just to look bigger?

Occasionally — some clients and agencies genuinely will not contract with a sole trader. But it is a real ongoing cost in fees and filings, so check whether the clients you actually want care, rather than assuming they do.
