One Doc Home Loan: Tradies Moving to Pty Ltd
Changing your business structure from sole trader to Pty Ltd changes how a lender reads your income for a One Doc home loan. The trade work is the same, the clients are the same, but the entity is brand new — and that creates a serviceability gap you need to plan around. This post covers the home loan side only. If you are also sequencing business facilities during the change, see the Entity-Change Bridge guide for asset finance, LOC and working capital timing.
Quick Answer
A One Doc home loan can bridge the income-verification gap when you move from sole trader to Pty Ltd, because the lender relies on your accountant's certification of current income rather than historical tax returns filed under the old entity.
Why a Pty Ltd Transition Resets Your Serviceability Read
A lender assessing a home loan reads income through the entity that earns it. When you operate as a sole trader, your personal tax return is the income source — the lender matches your ABN to your individual return and assesses serviceability from there. The moment you register a Pty Ltd and begin invoicing through the company, that personal income trail stops. Even if you are performing identical work for identical clients, the company is a separate legal person with its own ABN and its own tax history — which, in the first year, is zero.
Most full-doc lenders require at least one completed financial year of company tax returns before they will assess income from a Pty Ltd. For a tradie who transitions mid-financial-year, that means a potential wait of 12 to 18 months before a standard home loan application can be lodged under the new entity. During that window, your borrowing power under the conventional full-doc pathway is effectively paused.
This is the specific problem a One Doc home loan solves. Instead of relying on completed tax returns, the lender accepts a single document — typically an accountant's letter — certifying your current income. The accountant confirms that the income flowing through the new Pty Ltd represents the continuation of the same trade activity previously conducted as a sole trader. That continuity statement is what unlocks the serviceability read.
For a deeper look at how entity choice shapes lender appetite across all facility types, see the Sole Trader vs Pty Ltd vs Trust guide. If your transition also involves setting up a trust structure, the One Doc for Builders via a Trust post covers that specific pathway — different entity, different serviceability read.
What Lenders Check During the Changeover Window
The lender is not assessing your Pty Ltd as a start-up. They are assessing whether the Pty Ltd is a continuation of an established trade practice under a new structure. These are the specific data points the credit assessor reviews when a One Doc application arrives mid-transition.
The new Pty Ltd ABN should be registered and active. But the assessor also checks your prior sole trader ABN — its age, GST registration history, and activity status. A sole trader ABN with several years of active GST history tells the lender this is not a new venture.
The accountant certifies that the Pty Ltd carries on the same trade activity as the prior sole trader operation. The letter must state a current gross and net income figure, confirm the business has been operating continuously (under either entity), and be dated within 90 days of application.
At least one BAS lodged under the Pty Ltd ABN demonstrates revenue is flowing through the new entity. Quarterly BAS lodgements showing consistent turnover significantly strengthen the application.
The lender reviews three to six months of the Pty Ltd's business account to confirm that invoiced income is being deposited consistently. Irregular or lumpy deposits are common in trade — the lender expects variation, but the overall pattern should match the accountant's certified income figure.
The assessor confirms how you draw income from the Pty Ltd — whether as a director's salary, dividend, or a combination. This determines the income figure used for servicing. If you are paying yourself a modest wage and retaining profit in the company, the lender may add back retained earnings based on the accountant's certification.
ASIC's MoneySmart guide to choosing a home loan explains the general principle of responsible lending obligations — the lender must verify that you can afford the repayments without substantial hardship. One Doc does not bypass this. It changes the verification method, not the standard.
When the Timing Strengthens the Application
The strongest One Doc applications during a Pty Ltd transition come from tradies who time the home loan submission to land after at least one BAS cycle under the new entity. That gives the lender a revenue trail in the company name — short, but enough to corroborate the accountant's letter.
Stronger Fit
- Pty Ltd registered 3+ months ago with at least one BAS lodged
- Sole trader ABN was active 2+ years with clean GST history
- Accountant's letter explicitly states income continuity from prior entity
- Director's wage or distribution pattern is consistent and documented
- Existing debts (ute finance, tools) are current and structured
Gets Tricky
- Pty Ltd registered less than 30 days ago with no BAS yet
- Sole trader ABN was cancelled before the Pty Ltd was set up (gap in trading)
- Accountant's letter uses projected income, not current/historical figures
- No bank statements under the Pty Ltd name yet
- Outstanding ATO debt or overdue BAS from the sole trader period
If your Pty Ltd is less than three months old, the application is still possible — but the lender will lean more heavily on your sole trader history and the accountant's certification. The further you are into the first BAS cycle, the cleaner the file reads. For tradies who have already been through a One Doc application under a different scenario, the One Doc home loans for tradies guide covers the general eligibility framework.

How to Sequence the Home Loan Around the Entity Change
The order in which you do things matters. Registering the Pty Ltd, moving your invoicing across, lodging your first BAS, and then applying for the home loan is the correct sequence. Applying before the Pty Ltd has any trading history forces the lender to treat the application as if you are self-employed with zero history under the borrowing entity — even though your trade record is years long.
If your transition is also triggering changes to your business finance — a new asset finance facility under the Pty Ltd, a line of credit, or working capital — the sequencing becomes more complex. The Entity-Change Bridge guide covers the business-facility side of that process. The key principle: lodge the home loan application first, because home loan serviceability is assessed on your total debt exposure. Adding a new business facility before the home loan settles can reduce your borrowing capacity.
One thing the entity change does not reset is your personal credit file. Defaults, late payments, and enquiry history from your sole trader period carry forward into any application lodged under the Pty Ltd. Similarly, existing finance commitments — a chattel mortgage on a ute, a low doc equipment facility — remain on your personal servicing calculation regardless of which entity holds the asset. The lender still assesses the same core factors: your ability to service repayments from current income, your loan-to-value ratio, your existing debt commitments, and your credit history.
For tradies who earn a mix of subcontractor and direct client income, the Pty Ltd transition adds a layer of complexity around how the accountant splits and certifies that income. The mixed subcontractor income post covers that specific scenario in detail. The Tradie Hub has the full library of tradie-specific finance guides across asset, cashflow and home loan pathways.
Moving from sole trader to Pty Ltd does not stop you from getting a home loan — but it changes the way lenders verify your income. A One Doc home loan bridges the gap by relying on your accountant's certification of current income rather than waiting for the new entity to file its first full-year tax return. The strongest applications land after at least one BAS cycle under the Pty Ltd, with a clear continuity statement from your accountant and bank statements showing trade income flowing through the company account.
Key takeaway: Time the home loan application to land after the Pty Ltd's first BAS lodgement — that single data point turns a thin file into a fundable one.Frequently Asked Questions
You can apply immediately after registration, but the application is significantly stronger once the Pty Ltd has at least one BAS lodgement and three months of bank statements showing trade income deposits. A One Doc home loan uses your accountant's certification rather than tax returns, so the lender can assess income from a new entity — but corroborating evidence from BAS and bank statements reduces the risk of the file stalling at verification. If your sole trader ABN had several years of active trading history, that prior record supports the application even in the first weeks of the Pty Ltd.
Under a One Doc pathway, the lender does not require your sole trader tax returns as a primary income document. The accountant's letter certifying current income under the Pty Ltd is the primary verification. However, some lenders may request the most recent sole trader return as a supporting document to confirm that the trade activity has a track record. This is a risk-layering check, not a serviceability calculation — the income figure comes from the accountant's certification, not the old return.
After. The strongest sequence is: register the Pty Ltd, move invoicing across, lodge at least one BAS under the new entity, then apply. Applying while still invoicing as a sole trader means the lender assesses income under the sole trader entity — which is simpler but may not reflect your long-term structure. If you know the Pty Ltd transition is happening within the next three months, discuss timing with your broker before submitting. The One Doc for tradies guide covers the general eligibility framework, and the tradie loan pack explains how to bundle home loan and business facilities in the right order.
It can, depending on how you draw income from the company. If you pay yourself a director's salary that is lower than your previous sole trader net income, the lender may assess a lower income figure — which reduces borrowing capacity. Some low doc and One Doc lenders will add back retained company profits based on the accountant's certification, but not all do. Your broker should model the serviceability calculation under both income structures before you lock in a salary level. The way you set up your director's remuneration in the first few months of the Pty Ltd directly affects what the lender sees when they assess your application.
An outstanding ATO debt from the sole trader period is a personal liability that appears on your individual credit assessment, regardless of which entity you now operate under. Most One Doc lenders will accept a formal ATO payment plan as manageable debt provided repayments are current. An overdue debt with no plan in place is a significant obstacle. If you have an existing ATO arrangement, the One Doc for tradies on ATO payment plans post walks through how lenders treat that specific scenario. Clearing or structuring the ATO debt before submitting the home loan application is the recommended approach.
