When assessing self employed income, lenders often start from your business net profit and add back certain expenses that are not ongoing cash costs, such as depreciation, the interest on debts being refinanced, and genuine one off costs. This can lift the income figure used for serviceability. What can be added back varies by lender, and your accountant should confirm the figures.
Written by Ross McFarlane, Licensed Mortgage Broker (Credit Representative 526725). About the authorA common frustration for business owners is being assessed on a net profit figure that looks lower than the money actually available to them, because that figure includes deductions that are not ongoing cash costs. This is where add backs come in. Here is how they work.
When a lender assesses self employed income, it often starts from your business net profit and then adds back certain expenses that reduced that profit on paper but are not ongoing cash outflows. Adding them back gives a figure closer to your real serviceable income, which can lift your borrowing capacity.
The items lenders may consider adding back commonly include depreciation, which is a non cash accounting expense, the interest on any debts you are consolidating or refinancing, and genuine one off costs such as a major equipment purchase or business setup expense that will not recur. Superannuation contributions above the compulsory amount are sometimes considered too.
Add backs matter because they can be the difference between a net profit that looks too low to borrow what you need and a realistic income figure that supports it. For asset heavy businesses with large depreciation, or borrowers consolidating existing debt, the effect can be meaningful.
This is important: lenders differ in what they will add back and how. One lender may add back a particular expense that another will not, so the same financials can produce different income figures at different lenders. There is no single universal rule, which is why the choice of lender matters here.
Add backs are not a way to inflate income artificially. Lenders add back items that genuinely are non cash or non recurring, and they will want the financials to support it. An add back that is really an ongoing cost would not be accepted, and trying to treat it that way would undermine the application.
Because add backs come straight from how your financials are prepared and presented, your accountant is central to getting them right. Well prepared financials that clearly identify depreciation, one off costs and the like make it far easier for a lender to apply the add backs you are entitled to.
The practical lesson is that how your income is presented can change what you can borrow, within the bounds of what is genuine. A broker who works with self employed borrowers can identify lenders with favourable add back policies for your situation, usually at no cost to you, while your accountant ensures the financials support it.

When assessing self employed income, a lender starts from business net profit and adds back certain expenses that are not ongoing cash costs, such as depreciation, the interest on debts being refinanced, and genuine one off costs, to get a figure closer to your real income.
Commonly depreciation, the interest on debts being consolidated or refinanced, and genuine one off or non recurring costs. What is accepted varies by lender, so the same financials can produce different figures at different lenders.
No. Add backs must be genuinely non cash or non recurring, and the financials must support it. An ongoing cost cannot be added back. Your accountant should confirm what is appropriate.
