Add-Backs Explained: What Lenders Add Back and Why

If you've read our self-employed home loans overview or our article on full-doc versus low-doc lending, you'll already know the core problem: good tax planning can make your assessable income look smaller than your real earning capacity.

Add-backs are one of the main tools lenders use to close that gap, but they only close part of it. Understanding what actually qualifies as an add-back, and what doesn't, is often the difference between an accurate borrowing capacity estimate and a disappointing one.

What an add-back actually is

An add-back is an expense that reduced your taxable profit on paper but didn't reduce the cash actually available to you or your business. Lenders assessing a company or trust's financials will identify these items and add them back to the bottom-line profit figure, arriving at a number that more closely reflects real serviceability rather than taxable income.

The logic is straightforward: if an expense didn't cost you cash, it shouldn't count against you when a lender is working out whether you can afford loan repayments.

What typically qualifies

Depreciation and amortisation are the most common add-backs, since both reduce taxable profit without any cash leaving the business. One-off or non-recurring costs sometimes qualify too, such as a one-off legal expense, a relocation cost, or an interest expense tied to a debt that won't continue after settlement. Some lenders will also consider a portion of directors' superannuation beyond the compulsory minimum, though this varies and shouldn't be assumed without checking.

The common thread is that each item is either genuinely non-cash, or genuinely won't recur, rather than being a normal, ongoing cost of running the business.

What doesn't qualify, and why this matters more than most people expect

This is the part that can trip people up. Add-backs don't reach structural tax planning, income splitting through a family trust to lower-taxed beneficiaries, standard superannuation contributions, or deferred income recognition. These strategies genuinely reduce the income sitting with the business entity - there isn't any non-cash component for a lender to add back, so the gap between taxable income and real earning capacity stays open regardless of how thorough the add-back assessment is.

A company or trust with real capital expenditure has meaningful add-back opportunity. A sole trader typically doesn't, since there's less scope for the kind of non-cash and one-off items add-backs are built around, so the original tax-planning gap tends to sit closer to what the tax return shows.

A comparison

	Business A (company, capital-heavy)	Business B (trust, income-split)
Taxable income shown	Lower than real earnings	Lower than real earnings
Main cause of the gap	Depreciation on equipment, one-off legal cost	Distributions to lower-taxed family beneficiaries
Add-back impact	Meaningful, both items are non-cash or one-off	Minimal, distributions generally aren't an add-back item
Outcome	Assessed income moves closer to real earnings	Gap largely remains, low-doc may be the better fit

This example is illustrative only. Every lender applies its own policy to what it will and won't accept.

Getting an accurate picture before you apply

The practical takeaway is that add-backs are worth raising with your accountant and broker together, before you apply, not after a preliminary assessment comes back lower than expected.

If your accountant already knows which expenses are genuinely add-back eligible, that information can be prepared and presented properly from the start, rather than uncovered lender by lender.

Our borrowing capacity calculator applies a broad, self-employed-specific adjustment to give you a general starting estimate, but it isn't a substitute for a proper assessment of your add-back position. That level of detail only comes from working through your actual financials with your accountant and broker.
