Common Mistakes Self-Employed Borrowers Make

Self-employed borrowers often approach lenders differently to PAYG applicants, yet the same core serviceability principles apply.

Lenders assess your taxable income, not your turnover. That distinction trips up many applicants who run profitable businesses but minimise tax through legitimate deductions. A cafe owner in Rushcutters Bay earning $180,000 in revenue might show $68,000 in taxable income after claiming depreciation, vehicle expenses and superannuation contributions. The lender sees $68,000. Your accountant's focus is reducing tax. The lender's focus is proving you can service debt at your taxable income plus three percentage points.

Claiming Every Deduction Then Wondering Why Borrowing Power Dropped

Your taxable income determines your borrowing capacity. Lenders add back certain non-cash deductions like depreciation, but most expenses you claim reduce the income figure they use to assess serviceability. Consider a buyer who operates a small consultancy and nets $95,000 after claiming $22,000 in home office expenses, travel and professional subscriptions. The lender calculates serviceability on approximately $95,000 plus depreciation add-backs, not the gross figure before deductions. At current variable rates, that income supports roughly $550,000 to $600,000 in borrowing, depending on other commitments. If the same buyer had claimed $10,000 less in deductions, their taxable income would sit at $105,000 and borrowing capacity would increase by around $60,000 to $70,000. The after-tax cost of claiming those deductions is roughly $3,700. The cost in lost borrowing power is ten times that amount.

If you're planning to purchase within the next 12 to 18 months, speak to a broker before lodging your next tax return. Some deductions are worth deferring. Others, like superannuation contributions or genuine business reinvestment, can be structured in ways that preserve both tax efficiency and borrowing capacity. A home loan pre-approval application completed before you lodge gives you time to adjust your return if needed.

Switching Between Company, Trust and Individual Structures Mid-Application

Lenders treat income from different entity structures in different ways. A sole trader's taxable income is assessed directly. A company director's income might be assessed as a combination of salary, dividends and retained earnings, depending on the lender's policy and whether you own more than 20% of the company. Switching structures between tax years, or declaring income across multiple entities, adds complexity and often delay.

In our experience, applicants who operate through a discretionary trust and distribute income unevenly across beneficiaries face the most serviceability friction. A physio in Double Bay might distribute $80,000 to themselves and $40,000 to a spouse in one year, then reverse that split the following year for tax planning purposes. The lender will typically take the lower of the two years, or apply a more conservative averaging method. If you've switched from sole trader to a company structure in the past two years, expect the lender to request both your individual and company tax returns, plus financials prepared by your accountant. That's not a red flag, but it does extend processing time and requires your accountant to confirm ongoing income in writing.

Providing Two Years of Tax Returns When You Need More Context

Most lenders ask for two years of tax returns and two years of Notices of Assessment. That's the baseline. If your income fluctuates, or you've recently changed business models, two years might not tell the full story. A contractor who earned $110,000 two years ago and $92,000 last year will be assessed at $92,000 or an average of $101,000, depending on the lender. If that income drop was due to parental leave, illness or a planned sabbatical, and your current year is tracking back toward $110,000, you'll need additional documentation to support that narrative.

Providing a letter from your accountant confirming your year-to-date income, a profit and loss statement for the current financial year, and an explanation for any material variation between years gives the lender enough context to make a decision in your favour. We regularly see this approach lift a declined application into conditional approval. The alternative is waiting another 12 months until your third year of returns shows the upward trend. If you're applying through the Australian Government 5% Deposit Scheme, where income caps don't apply but serviceability is still tested, that additional context becomes even more important.

Assuming ABN Age Equals Trading History

You registered your ABN five years ago. You lodged your first tax return as a sole trader three years ago. The lender counts three years of trading history, not five. If you've been operating under a company structure for 18 months after spending three years as a sole trader, some lenders will accept 18 months of company financials on the strength of your prior sole trader history. Others won't. The policy varies by lender, and applicants who assume their ABN registration date is the relevant metric often find themselves ineligible for products they expected to access.

For buyers purchasing in Rushcutters Bay, where the typical unit price sits at approximately $1,211,000 and yields are strong at 4.76%, understanding which lenders accept shorter trading histories under specific structures can mean the difference between accessing investment loan options now or waiting another year. Your ABN age matters less than your tax return history and whether your income can be verified across a consistent structure.

Mixing Personal and Business Expenses in the Same Account

Lenders review your bank statements over a three to six month period. If your business income and personal expenses run through the same transaction account, the lender sees every Uber Eats order, every weekend purchase and every cash withdrawal alongside your client payments and supplier costs. That's not inherently a problem, but it makes the assessment slower and increases the chance the lender will ask for statutory declarations explaining specific transactions.

A solicitor operating from a serviced office in Double Bay might receive $18,000 a month in client payments into a personal account, then pay $4,500 in rent, $1,200 in software subscriptions and $800 in professional indemnity insurance from the same account, mixed in with mortgage repayments, groceries and school fees. The lender has to reconcile which outgoings are business-related and which are personal. If your business expenses are genuinely $6,500 a month, but your personal account shows $9,200 in monthly outgoings, the lender will likely assess your living expenses at the higher figure unless you provide clarity. That reduces your serviceability.

Separating your business and personal banking three to six months before you apply eliminates this issue. If you've already applied and your statements are mixed, your broker can prepare a spreadsheet categorising each transaction and provide it with a covering letter. It's additional work, but it's better than having the lender assume every outgoing is a personal commitment.

Not Declaring Upcoming Contract Renewals or Expanded Client Engagements

Serviceability is forward-looking. If you're a contractor with $105,000 in taxable income last year, and you've just signed a contract variation increasing your day rate by 15%, that future income can sometimes be included in your assessment. You'll need a signed contract, a letter from the client or employer confirming the arrangement, and evidence the income has started flowing into your account. Lenders won't take your word for it, but they will consider verified future income where the documentation supports it.

This is particularly relevant for applicants using a split rate structure, where a portion of the loan is fixed and a portion remains variable. The fixed portion might be assessed at a slightly higher serviceability buffer depending on the term, and proving your income is increasing rather than static can give you access to a higher loan amount without waiting another 12 months for your next tax return. If you've recently expanded into a new service line or picked up a retainer client, bring that documentation to your broker before they submit your application.

Relying on Gross Profit When the Lender Wants Net Taxable Income

Gross profit and taxable income are not the same figure. Gross profit is your revenue minus cost of goods sold. Taxable income is what remains after you deduct operating expenses, depreciation, interest and other allowable claims. A tradie operating in the eastern suburbs might generate $240,000 in revenue, spend $95,000 on materials and subcontractors to produce a gross profit of $145,000, then claim $48,000 in vehicle, tool and administrative expenses to arrive at a taxable income of $97,000. The lender assesses serviceability on $97,000 plus add-backs, not $145,000.

Applicants often reference their gross profit or EBITDA figure in conversation and assume that's the income the lender will use. It isn't. If your business shows strong gross profit but low taxable income due to high discretionary expenses, you'll need to decide whether those deductions are worth the serviceability trade-off. For someone looking to secure an owner-occupied home loan in Woollahra, where the median house price is $4,900,000 and borrowing requirements are substantial, restructuring your deductions in the year before you apply can increase your borrowing capacity by $100,000 or more.
