If you're self-employed and your tax return shows a lower income than you actually earn, you're not imagining the problem. Lenders don't simply read the bottom line from your return and move on. Most will add certain non-cash and one-off expenses back into your assessable income before running the numbers, which can materially change what you're eligible to borrow.

The catch is that add-back policies differ between lenders. Some are generous with depreciation and one-off costs; others take a conservative view and add back very little. For a sole trader, a company director or a trust beneficiary in Logan, QLD, that difference can shift borrowing capacity by tens of thousands of dollars, or move an application from declined to approved.

Our team works through self-employed home loans across Logan, QLD every week, comparing across 60+ lenders to find which assessment approach works best for each client's structure and income profile.

What does it mean when a lender adds back an expense?

An add-back is when a lender takes an expense that reduced your taxable income and adds it back into their assessment of what you actually earn. The logic is straightforward: some deductions lower your tax bill without reducing your real cash flow. Depreciation on equipment is the clearest example. You claim it on your return, it reduces your taxable income, but no money left your account that year. A lender who ignores that would understate your genuine income, so they add it back before calculating what you can service.

Which expenses do lenders actually add back?

Not every deduction qualifies. Lenders distinguish between expenses that reflect genuine, recurring cash outflows and those that are accounting entries or one-off events. The ones most commonly added back sit in a consistent category regardless of lender.

The add-backs most lenders recognise:

• › Depreciation: the most universal add-back. It reduces taxable income but involves no cash outflow in that period.
• › One-off or non-recurring expenses: a legal dispute, a fit-out cost, a one-time restructuring expense. Where a lender is satisfied it won't recur, they may add it back.
• › Interest already claimed as a deduction: where business interest expense is claimed on the return, some lenders add it back to avoid double-counting it against serviceability.
• › Net profit add-backs for company structures: where income flows through a company and the applicant draws a salary, some lenders look at the company's retained profit alongside the declared salary.
• › Superannuation contributions above the minimum: voluntary super contributions made by the business on the owner's behalf, above the guarantee rate, are added back by some lenders.

What lenders typically won't add back:

• › Recurring operating expenses: rent, wages, subscriptions, insurance. These reflect genuine ongoing costs of running the business and stay in the assessment.
• › Motor vehicle expenses where personal use is included: if the vehicle claim mixes business and personal use, most lenders won't add any portion back.

What documentation do lenders need to assess add-backs in Logan, QLD?

The standard starting point is two years of personal tax returns and two years of business tax returns, including the associated notices of assessment. Most lenders want to see both years to establish a consistent income pattern and to identify which deductions are recurring versus one-off.

Where one year may be accepted

Some lenders will assess on a single year's return where the business is genuinely newer, or where year two is materially higher than year one and the applicant can show the reason. An accountant's letter explaining the income movement is often what makes the difference. Not every lender on the panel accepts this, which is one of the key policy differences worth comparing before you apply.

Supporting documentation for add-back claims

A depreciation schedule from your accountant is usually required to support a depreciation add-back. For one-off expenses, a letter from your accountant confirming the non-recurring nature of the cost is the standard evidence. Without that documentation, most lenders will treat the expense as ongoing and leave it in.

Business bank statements for the last six to twelve months are also commonly requested alongside the tax returns, partly to verify cash flow and partly to cross-check that the income the returns show aligns with what's actually moving through the business account.

How do add-backs affect your borrowing capacity in Logan, QLD?

The practical effect depends on the scale of the deductions being added back and which lender's policy applies. A business owner with a significant depreciation schedule on equipment, or who had a genuine one-off legal cost in one year, can see their assessed income change meaningfully between lenders.

To illustrate the mechanism: if your return shows a taxable income of $100,000 but includes $30,000 in depreciation and a $15,000 one-off expense that your accountant confirms won't recur, a lender that adds both back is assessing you on $145,000. A lender that only adds back depreciation is assessing you on $130,000. A lender that adds back neither is working from $100,000. All three are looking at the same tax return. The difference in borrowing capacity across those three assessments is real and material.

In suburbs like Springwood, Browns Plains or Loganholme, where house medians range from the mid-$800,000s to over $880,000, the add-back calculation can be the difference between qualifying for the property you want and falling short on paper.

When does a lender's add-back policy not help you?

Add-backs don't rescue every situation. Where the business has genuinely declining revenue across two years, adding back depreciation on a shrinking income base doesn't change the trend a lender sees. Most lenders will average the two years or take the lower year where income is falling, and no add-back policy overcomes a trajectory that suggests the business is contracting.

The same applies where the expense being claimed as a one-off keeps appearing year after year. A legal cost claimed in both years is no longer a one-off, and most credit assessors will notice and leave it in. An accountant's letter asserting non-recurrence for an expense that recurred is unlikely to be accepted.

It's also worth being clear that add-backs increase your assessed income on paper, but they don't change the APRA serviceability buffer that lenders apply on top of your actual rate. Every lender still stress-tests your repayments at a rate roughly 3.0% above the loan rate you'll be charged, regardless of how generous their add-back treatment is. Add-backs help with the income side of the equation; they don't reduce the rate-sensitivity test.

How does lender policy difference compare on add-backs?

The options worth understanding before you apply sit across three broad positions. Most lenders don't publish their add-back policy in the same place or with the same transparency, which is where comparing across a panel matters.

The positions worth comparing:

• › Broad add-back policy: depreciation added back · one-off expenses considered with accountant's letter · interest add-back included · suits complex structures
• › Depreciation-only policy: depreciation added back · one-off expenses left in · simpler evidence required · more predictable assessment
• › Conservative policy: minimal or no add-backs · taxable income taken at face value · lower assessed income · suits simple PAYG-equivalent structures

Whether the broader policy is available to you depends on which lenders your broker has access to and on the specifics of your business structure, which is worth a conversation before you apply.

What goes wrong when self-employed borrowers apply without comparing add-back policies?

Where applications run into trouble:

• › Applying to the wrong lender first: a conservative lender that adds back nothing is a hard decline for a borrower whose income depends on depreciation and one-off adjustments. That decline sits on the credit file, which affects the next application.
• › Missing documentation for the add-back: a depreciation add-back without the schedule, or a one-off claim without an accountant's letter, is treated by most lenders as a recurring expense and left in. The add-back fails on a technicality, not on merit.
• › Inconsistent income across the two years: where year one is materially lower than year two, many lenders average the two or take the lower figure. If the reason for the jump isn't explained upfront, the assessment comes back conservative and the borrower is surprised.
• › Assuming your own bank will be the most flexible: your business bank sees your cash flow every day, but their lending policy on add-backs is no more generous than any other lender's, and often less so. The right lender for your add-back profile is rarely the one you already bank with.

Frequently Asked Questions

What is an income add-back in a home loan application?

An add-back is an expense from your tax return that a lender adds back into your assessable income because it reduced your taxable income without reducing your actual cash flow. Depreciation is the most common example.

Can all self-employed borrowers use add-backs in Logan, QLD?

Most can, but the expenses must be documented and meet the specific lender's add-back criteria. An accountant's letter and a depreciation schedule are usually required to support the claim.

Do lenders add back depreciation automatically?

Not automatically. You need to provide the depreciation schedule, and the lender's credit policy must include depreciation as an approved add-back. Policies differ between lenders, so not every lender will apply it.

Will a one-off legal cost be added back to my income?

Some lenders will add it back if your accountant confirms in writing that the expense was genuinely one-off and won't recur. Where it appeared in both years' returns, it's unlikely to be treated as non-recurring.

Is the add-back treatment better at one type of lender than another?

Generally, specialist and non-bank lenders tend to have broader add-back policies than major banks, though this varies. Comparing across the panel before applying is the most reliable way to find the right fit for your structure.

Should I use a mortgage broker or my own bank for a self-employed loan in Logan?

A mortgage broker, every time. Your own bank assesses your add-backs under one policy; a broker compares how multiple lenders treat your specific returns and places the application with the one whose policy works in your favour.

Your Next Steps

Getting the add-back calculation right as a self-employed borrower or business owner is often the whole game. A lender that recognises your depreciation, your one-off costs and your business structure can produce a very different number from one that doesn't, and the difference is worth understanding before you apply anywhere.

The right lender for your add-back profile depends on your situation, and that's a conversation worth having. Talk to the Cube Loans team or call 1800 774 756, and we'll compare your options across 60+ lenders.
