Changing from a sole trader to a company can leave a home-loan application with records belonging to different entities and periods. The useful task is to explain the transition: what continued, what changed and what the available evidence actually shows.
A company's new ABN does not describe the whole operating history. Equally, earlier sole-trader activity does not automatically satisfy a lender's requirements for the company or the proposed loan. This guide is for an individual applying for a home loan in their own name after a business-structure change. It does not recommend incorporating or calculate borrowing capacity.
What changed when you incorporated?
Government guidance explains that a company is a separate legal entity and that a sole-trader ABN cannot be transferred to the new company. The company's registration and the earlier business's activity therefore need to be identified separately.
For a lending discussion, describe more than the new entity name. What happened to the work being done, ownership, customers, contracts and existing commitments? Was there a break in operations? Which parts are supported by records, and which are only an explanation awaiting evidence?
Those are preparation questions, not a test that proves continuity. Obtain appropriate accounting, tax and legal advice about the change itself and any transfer of assets, contracts or obligations.
Which history can you actually show?
Separate the dates of registration, actual trading and the periods covered by financial records. A company incorporated in February might start the stated trading activity in April; neither date should quietly replace the other.
Also keep the owner-payment arrangements clear. The government's sole-trader and company comparison explains that company money belongs to the company. Sole-trader drawings and wages from an owned company are different records. Our business-income guide explains those distinctions without turning them into a lender-income total.
If records span the change, identify which entity and period each covers. Ask the accountant to explain any gaps, overlapping amounts, opening balances and changed remuneration. An opening balance is not automatically new earnings, and a transfer between accounts is not automatically extra income.
A hypothetical transition: old records, new company
These dates, records and explanations are invented. They are not a client case, professional certification or an approval example. As at 19 October 2026, the supplied information says:
- A fictional business-history statement places the individual's sole-trader operations between 1 July 2022 and 31 March 2026.
- The company was incorporated on 15 February 2026 and its ABN registered on 16 February.
- A separate fictional statement says the company started the activity on 1 April. A transition note says the same individual continued providing the same type of service.
- The available sole-trader income schedule covers 1 July 2025 to 31 March 2026. The company profit-and-loss statement and the individual's company payroll record cover 1 April to 30 June 2026.
The records cover successive parts of the financial year under different structures. The payroll record overlaps the company accounts' period; its relationship to the expenses in those accounts still needs explaining. It is not automatically another business result to add on top.
The description of continuing service is available, but no customer contracts or asset-transfer documents have been supplied. The preparation output is therefore specific: the entity and record dates are identified; the extent of operational continuity, transferred obligations and the relationship between payroll and company results remain to be substantiated. The lender has not confirmed what history or income it will accept.
Now remove the sole-trader business-history statement, company trading-start statement and transition note. The old operating dates, new trading start and continuity become unknown. The remaining registration dates and financial-record coverage do not establish those missing facts. This is why a timeline needs to show its evidence as well as its dates.
Why do later receipts need their own explanation?
Extend the same fictional example: a deposit appears on 20 July, matching the amount of an invoice dated 15 March. The payer reference, legal payee and accounting allocation have not been supplied.
The deposit should remain an unexplained receipt. Matching amounts do not establish which entity earned it, which period it relates to or whether it is already included in an income record. Ask the accountant to reconcile the invoice and payment before assigning it to the old or new business. Its arrival after incorporation does not, by itself, make it company earnings.
Similarly, do not combine a full-year figure with partial-year records without checking whether the same amounts are included twice. The purpose is to explain the evidence, not manufacture a larger income figure.
Does the lender have to accept the earlier history?
No acceptance follows from these examples. Westpac's public self-employed page states business-history requirements and separately says it may still be able to help where a business structure has changed. That invitation to discuss an application does not establish which earlier records count, what additional evidence is needed or whether a particular applicant qualifies.
Ask the proposed lender how it treats the current entity's history, whether it can consider the earlier activity and which records it needs to connect the two. A complete explanation or accountant's letter is not an approval, and another lender may have different requirements.
Our short-ABN guide separates registration, trading and evidence periods. The assessment-pathways guide explains why full-document, simplified and alternative-document approaches are not interchangeable promises of eligibility.
What should you clarify before applying?
A useful transition summary has three parts:
- Before and after: the relevant entities, actual operating dates, ownership and activities, distinguishing supported facts from explanations still to verify.
- Records and unresolved relationships: the periods available, overlaps, changed owner payments and transfers that need an accountant's explanation.
- Lender questions: the history and income being proposed for assessment, the evidence requested and any decision or condition still outstanding.
Use the self-employed document checklist to organise the records rather than building a second document list here. If company salary, dividends or retained earnings are part of the discussion, the company-director income guide explains their different roles.
Flexdoc's residential lending service can discuss the proposed loan and the evidence available after the change. Book a conversation with the transition and remaining questions clearly identified.
