A consultant traded profitably as a sole trader for eight years, then incorporated nine months ago. Their final two personal tax returns show £140,000 and £155,000 of profit, while the company has no filed accounts and pays only a modest salary. The commercial activity may be continuous, but a lender cannot simply copy the former sole-trader profit into the company period without testing ownership, turnover, costs, extraction and current performance.
The Client Situation
The accountant may encounter:
- a sole trader who incorporated during the current tax year;
- a partnership whose trade moved to a company;
- a contractor who now invoices through a personal service company;
- a professional practice incorporating while clients and work remain the same;
- a retailer transferring stock, employees and premises;
- a business with goodwill, vehicles or equipment moved to the company;
- a VAT registration transferred or replaced;
- a director taking low salary while profit accumulates;
- a client who incorporated after a mortgage agreement in principle; or
- a company whose first statutory accounts are not yet due.
The accountant has usually advised on the structure for tax and commercial reasons. The mortgage issue should not overturn that advice automatically. It should be identified early enough to choose an appropriate evidence route or realistic timing.
The trade may be continuous in a commercial sense, but the sole trader and company are different legal persons. A lender can choose to recognise continuity; it should never be told that no change occurred.
What Officially Happens When the Structure Changes
GOV.UK states that a person changing legal structure—for example, becoming a limited company—must tell HMRC, register under the new structure and report the end of self-employment where applicable. A sole trader who stops must submit a final return, calculate final trading profit or loss and deal with assets, capital allowances, VAT, PAYE and other closing matters.
The new company separately needs:
- incorporation and ownership records;
- Corporation Tax registration when active;
- its own accounting records and period;
- a company bank account;
- VAT and PAYE registrations where required;
- contracts and invoices in the correct name;
- documentation for transferred assets, stock, goodwill and liabilities;
- director remuneration and dividend records; and
- annual accounts and confirmation filings.
These steps create a discontinuity in tax and legal evidence even where the client performs the same work for the same customers the next day.
How to Evidence Genuine Commercial Continuity
| Continuity factor | Supporting evidence | Potential break |
|---|---|---|
| Ownership/control | Sole trader becomes controlling director/shareholder. | New investors or control rights. |
| Trade/activity | Same services, products and market. | Materially different business model. |
| Customers | Contracts or recurring clients transferred. | One former client or entirely new book. |
| Premises/assets | Same premises and equipment documented. | Assets retained personally or sold elsewhere. |
| Employees | Team continues with lawful transfer/payroll. | New operation with no prior workforce. |
| Revenue trend | Monthly company turnover follows prior trade. | Long gap or sharp unexplained fall. |
| Costs/margins | Comparable activity and normalised margins. | Company adds major overheads or staff. |
| Timing | Clear cessation and company start dates. | Overlapping invoices and unreconciled accounts. |
A short accountant chronology can tie these points together: final sole-trader date, company start date, reason for incorporation, assets and contracts transferred, ownership, turnover to date and current profit.
Which Income Might a Lender Use?
| Method | Evidence base | Limitation |
|---|---|---|
| Historic sole-trader profit | Final accounts and personal tax documents. | Does not prove current company performance. |
| Salary and dividends | Payroll, dividend records and company accounts. | May understate retained earnings. |
| Salary plus company profit | Accounts or acceptable current figures. | Only under lenders with suitable director policy. |
| Continuity blend | Old profit plus current company evidence. | Specialist policy and strong reconciliation required. |
| First completed company accounts | Signed accounts and tax computation. | May require waiting and still provide short history. |
| Forecast/current managements | Actual months, contracts and forecast. | Not all lenders accept prospective income. |
The most generous-looking method is not automatically the correct one. The lender may use an average, the latest lower figure, actual remuneration or an adjusted company profit. Willow establishes the policy; the accountant confirms the figures and limitations.
Why the Company Result May Differ From the Sole Trade
Even with commercial continuity, profit can change because the company:
- pays a director salary and employer costs;
- employs staff previously subcontracted;
- owns or leases assets differently;
- claims different costs or capital allowances;
- pays pension contributions;
- services asset-transfer or director-loan balances;
- takes on financing, premises or insurance;
- uses a different accounting period;
- recognises work in progress differently;
- has Corporation Tax rather than personal Income Tax;
- retains profit rather than paying dividends; or
- has changed prices, customers or activity.
The accountant should prepare a like-for-like bridge where the differences are material. Do not “add back” genuine new company costs solely to recreate the old sole-trader profit.
Transferred Assets and Director’s Loan Accounts
Incorporation may involve the company acquiring goodwill, stock, equipment, vehicles, debtors or other assets from the proprietor. The consideration may create a director’s loan account, shares or other entries.
For mortgage purposes:
- a director’s loan credit is not recurring income;
- repayment may produce cash but differs from salary or dividends;
- personally retained assets may still have associated debt;
- company cash used to repay the loan can reduce working capital;
- asset values and tax treatment require professional support;
- personal guarantees or finance may continue after transfer; and
- the lender may want to understand unusually large balance-sheet movements.
The accountant advises on the transaction and entries. Willow ensures that cash received from loan repayment is not mislabelled as sustainable mortgage income.

When Mortgage Timing and Incorporation Interact
Four moments deserve review:
- Before incorporation: test whether a planned mortgage relies on sole-trader history and whether suitable continuity lenders exist.
- Immediately after incorporation: establish correct contracts, bank receipts, payroll and records from day one.
- Before first accounts: decide whether current managements and continuity evidence are sufficient or whether waiting improves the market.
- After first accounts: compare the new company result, remuneration and retained profit with the historic trade.
A client should not reverse or postpone sound tax and legal advice solely to fit a mortgage product without comparing the complete consequences. Equally, incorporation immediately before exchange can remove a lender that expected an established sole trader. Early coordination preserves options.
Worked Example: Eight Years Trading, Nine-Month Company
A technology consultant earned sole-trader profits of £140,000 and £155,000 in the last two completed tax years. They incorporated nine months ago, remain the sole owner and director, serve the same clients and have billed £135,000 through the company. Management accounts show £108,000 profit before tax and director remuneration. The client has taken £12,570 salary, no dividends and £25,000 repayment of a director’s loan created on incorporation.
A lender using salary and dividends alone may see £12,570. Another lender may consider company profit under its director rules. A continuity lender may assess the historic sole-trader record alongside current company managements. The £25,000 loan repayment is cash received but not recurring earnings.
The accountant supplies final sole-trader accounts, tax evidence, company managements, ownership, bank statements, customer continuity and an income bridge. Willow identifies an appropriate policy before submission. The result depends on verified sustainability, affordability and the lender’s approach—not a claim that the company itself has traded for eight years.
When Continuity Is Weaker Than It First Appears
Expect closer review where:
- ownership changed materially;
- the company acquired a different business;
- customers did not transfer;
- there was a long trading gap;
- the client changed industry or service;
- turnover or margin fell sharply;
- the company carries significant new debt;
- the former trade retained liabilities or contracts;
- income now depends on one new customer;
- management accounts exclude major costs;
- the client draws more cash than profit supports; or
- tax and filing records do not agree on cessation dates.
In these cases, the new company may need to build its own history. A clear “not yet” is better than forcing an application through an unsuitable continuity narrative.
Where the Professional Boundaries Sit
The accountant advises on incorporation, cessation, asset transfer, tax registrations, accounts, director remuneration and the continuity figures. The solicitor advises on transferred contracts, employees, assets, liabilities and corporate documents where required.
Willow identifies lenders that can consider the actual structure, selects a suitable income method within lender rules and coordinates underwriting. The lender decides whether and how much of the pre-incorporation history it accepts.
Willow does not recommend incorporation for tax reasons or determine the company’s profit. The accountant should not promise that trading continuity guarantees mortgage continuity.
Common Mistakes to Avoid
- Saying only the name changed: the legal taxpayer changed.
- Calling the company eight years old: distinguish trade from entity age.
- Using sole-trader profit without current company evidence: performance may differ.
- Using salary alone without checking policy: retained profit may be relevant.
- Calling loan repayment income: it is a balance-sheet movement.
- Ignoring new company costs: genuine expenses reduce sustainability.
- Overlapping invoices across structures: cessation and start dates must reconcile.
- Waiting for filed accounts unnecessarily: some lenders consider continuity earlier.
- Assuming every lender accepts continuity: policy varies.
- Incorporating during an application silently: material changes must be disclosed.
- Letting tax drive mortgage facts: report the actual structure accurately.
- Applying before the evidence bridge exists: avoid preventable declines.
When to Involve Willow
Refer the client when:
- incorporation is planned within the next year;
- a mortgage agreement in principle already exists;
- the company has no filed accounts;
- historic sole-trader profit is materially higher than salary;
- the same trade and customers continued;
- new shareholders or directors joined;
- assets or goodwill created a director’s loan;
- the company’s margins differ from the sole trade;
- a high-value mortgage depends on retained profit;
- the client wants to buy before first accounts;
- another broker said the history reset automatically; or
- the accountant wants lender requirements checked before restructuring.
An anonymous outline should include incorporation date, former structure, trading history, owners, trade, customers, historic profits, company turnover and profit to date, salary, dividends, loan repayments, mortgage requirement and timing.
Did the Business Incorporate Before the Mortgage Was Considered?
Share a redacted history, continuity and current-company outline before the client waits unnecessarily or applies under the wrong income method.
Frequently Asked Questions
A lender can recognise a continuing trade when the accountant proves the bridge and the selected policy accepts it, while still treating the new company as a separate legal borrower and income source.
Can a lender use sole-trader history after the client incorporates?
Potentially. Some lenders can consider continuity where the same owner, trade, customers and activity moved into a limited company, supported by final sole-trader accounts and current company evidence. Other lenders require completed company accounts.
Is the limited company legally the same business as the former sole trader?
No. The company is a separate legal person. Commercial continuity may be strong, but contracts, assets, liabilities, tax registrations and income now belong to a different entity and must be documented correctly.
Which income figure might the lender use after incorporation?
Depending on policy, it may use salary and dividends, salary plus company profit, completed sole-trader profit combined with current evidence, or another accepted director-income method. The accountant does not choose the lender’s calculation.
Does incorporating reset the client’s trading history to zero?
Not always for underwriting, but it can narrow lender choice. The evidence should prove what continued and disclose what changed rather than simply claiming the company has traded for the sole trader’s full history.
Should a client delay incorporation until after the mortgage?
That is not a decision for the broker alone. Tax, legal and commercial advice may support incorporation. Where possible, test mortgage implications before changing structure or committing to a property.
When should Willow become involved?
Before incorporation where a mortgage is planned, or immediately afterwards before an application. Willow can identify lenders willing to assess continuity and specify the evidence route.
