Self-Employed Home Loan Income Requirements: What the Bank Assessor Is Actually Doing

By Andrew Paterson

If you run your own business, you have probably heard it a hundred times: “You need two years of tax returns.”

That is mostly true. The bigger question is how a lender reads those returns, because that decides how much you can borrow.

Does the lender average two years, take the lower one or use your latest year? That one choice can shift your borrowing power by a large amount. For the broader mechanics, our guide on how lenders calculate how much you can borrow is a good starting point.

This is general information only and not personal credit or tax advice. Treat it as a map of how assessment works rather than a verdict on your own file.

Two years of financials is still the standard

For a full-doc application, most lenders still want two years of evidence. A typical list looks like this:

• Two years of personal tax returns
• Two years of business tax returns if you trade through a company, trust or partnership
• Matching ATO notices of assessment
• Business financials such as a profit and loss statement and balance sheet
• Recent BAS if you are registered for GST

You must register for GST once your business turnover reaches $75,000 a year, so most established businesses will have BAS on hand.

Timing matters too. Individuals lodging their own return have until 31 October, while clients of a registered tax agent can often lodge as late as March or May the following year.

That means many borrowers applying in late 2026 will still be assessed on the 2024-25 year. If your 2025-26 year was stronger, lodging early and getting your notice of assessment back can help.

How lenders work out self-employed income

The bottom line on your tax return is rarely the figure a lender uses. The assessor starts with net profit and then looks at the trend across your years.

• Stable or rising income: many lenders average the two most recent years.
• Falling income: most use the lower, more recent year and may ask you to explain the drop.
• A strong latest year: some lenders will use that year alone, usually with extra conditions.
• A newer ABN or heavily tax-minimised income: an alt-doc loan through a non-bank may be worth considering.

Lenders also watch for sudden jumps. Some limit how much of a sharp increase they will count, so a single boom year does not carry a loan it may not sustain.

Add-backs: where lenders differ most

Your assessable income is usually net profit plus add-backs. This is where two lenders can look at identical financials and reach very different numbers.

Add-backs that lenders commonly consider include:

• Depreciation
• One-off or non-recurring expenses you can document
• Personal super contributions claimed as a tax deduction
• Interest on business debts that will be paid out or refinanced
• Director’s wages and, with some lenders, retained company profits

Ordinary running costs stay as costs. Personal spending pushed through the business will not be added back either.

Instant asset write-offs deserve a closer look. Some lenders add the full amount back and others treat it more cautiously, which alone can move your borrowing capacity.

A worked example

Take a sole-trader electrician whose latest return shows net profit of $85,000. On paper that looks like an $85,000 income.

Now look at the add-backs in the same return:

• Depreciation on the ute and tools: $9,000
• A one-off equipment write-off: $4,000
• Deductible personal super contributions: $6,000

A lender that accepts all three assesses income of $104,000. That extra $19,000 a year can add tens of thousands of dollars to borrowing power, depending on the lender’s calculator and your expenses.

Same person, same return, different lender policy. That is the case for matching your file to a lender before you apply.

One year of financials at the major banks

All four major banks now offer a one-year income option for some self-employed borrowers. CBA moved in late 2024, NAB in early 2025 and Westpac in July 2025, while ANZ has offered a version for longer.

Each bank sets its own conditions, and they change. Broker summaries commonly list these:

• An LVR of 80% or below, although ANZ allows higher LVRs with LMI and a discount applied to your profit
• A final return lodged with the ATO and a notice of assessment, since an accountant’s draft is not enough
• Around two years of ABN registration, and often GST registration, to show trading history

If your business is newer or last year was your first strong year, this option can make a real difference to your timing. Confirm the current policy with each lender at application.

What if your ABN is less than two years old?

You still have options. Alt-doc and low-doc loans, mainly from non-bank lenders, can verify income without two years of returns.

Depending on the lender, you might use:

• Recent BAS, often six to twelve months
• Business bank statements
• An accountant’s letter or declaration confirming your income

Minimum trading history varies. Pepper Money, for example, asks for ABN and GST registration held for at least six months on its alt-doc loans.

Expect trade-offs. Rates are usually higher than comparable full-doc loans, and some lenders cap the LVR lower or apply LMI earlier. Our explainer on how lenders mortgage insurance works covers the basics.

Some borrowers start on an alt-doc loan and refinance to a full-doc rate once they have two years of returns. Whether that suits you depends on the costs involved, and it is a good moment to consider whether to fix or stay variable.

The one bad year problem

Plenty of business owners carry one weak year, whether from a quiet stretch, an illness or a lost contract.

A single soft year can often be placed. If your latest year shows recovery and you can document the cause, some lenders will lean on the recent year rather than the average.

An averaging lender might decline the application while another approves it comfortably. The financials are the same in both cases.

Why the serviceability buffer hits harder

APRA expects banks to test your repayments at 3 percentage points above the loan rate. A loan at 6% is therefore assessed as if the rate were 9%.

That buffer bites harder when you are self-employed, because it applies to an income you may have legitimately reduced through tax planning.

A second limit arrived on 1 February 2026. Banks and other APRA-regulated lenders can now write no more than 20% of new owner-occupier loans at a debt-to-income ratio of six or more. Investor lending has its own 20% limit.

The limit is measured across each bank’s total new lending, and non-bank lenders sit outside it. For some business owners near that ratio, a non-bank may be worth comparing.

Your pre-application checklist

A complete, tidy pack speeds everything up. For a broader plan, see our 6-month loan-ready countdown.

• Two years of personal and business tax returns, or your latest year if using a one-year option
• Matching ATO notices of assessment
• Business financials: profit and loss, balance sheet and depreciation schedule
• The last 12 months of BAS
• Business bank statements
• ABN and GST registration details
• An accountant’s letter if you are going alt-doc
• A list of your debts and credit limits

On that last point, lenders assess your credit card limit rather than the balance. A $20,000 card sitting at zero still reduces your capacity, as our piece on how your credit card limit affects borrowing power explains.

Buying your first home while self-employed

First-home buyers can combine federal and state help with any of the income options above.

Since 1 October 2025, the First Home Guarantee (now called the 5% Deposit Scheme) has no income caps or limit on places. The government guarantees part of the loan so eligible buyers can purchase with a 5% deposit and no LMI, within set price caps.

You still need to pass the lender’s serviceability test. Check the First Home Guarantee timelines and deadlines before you plan a settlement date.

In Victoria, eligible first-home buyers pay no stamp duty up to $600,000, with a sliding concession up to $750,000. A $10,000 First Home Owner Grant is also available for eligible new homes valued up to $750,000.

The takeaway

Self-employed lending has no single hurdle. The result depends on how each lender calculates your income and how well your file matches that lender.

Two years of returns is still the norm. One-year options, add-backs, recent-year treatment and alt-doc loans are where the flexibility sits.

If your income is uneven, growing fast or tied to a newer ABN, it is worth mapping your options before you apply.

General information only and not personal financial, credit or tax advice. Speak with a licensed credit adviser and your accountant about your circumstances. Lender policies on income, add-backs, one-year financials and alt-doc lending differ and change often, so confirm details at application.

Frequently asked questions

Do I really need two years of tax returns for a self-employed home loan?

Not always. The major banks each have a one-year option for some borrowers, usually with an LVR limit, a lodged return with a notice of assessment and around two years of trading. Non-bank alt-doc loans can use BAS or bank statements instead.

What are add-backs?

They are expenses a lender adds back to your net profit because they do not reflect cash you need to live on, such as depreciation. Ask your accountant to show them clearly in your financials so an assessor can find them easily.

How do lenders handle falling income?

Most will use the lower, more recent year. A written explanation from you or your accountant, backed by evidence that trading has recovered, can help some lenders take a more favourable view.

Can I get a home loan if my ABN is under two years old?

Often, yes. Some non-bank lenders accept ABN and GST registration from six to twelve months, using BAS, bank statements or an accountant’s letter. Expect a higher rate and possibly a larger deposit.

Does a delay in lodging my tax return affect my loan?

It can. Most lenders assess only returns the ATO has processed, so a strong year still with your accountant may not count yet. Lodging early can bring a better year into play sooner.
