How much can add-backs increase my borrowing power?

The impact varies, but for some self-employed borrowers, accepted add-backs of $30,000–$50,000 a year can significantly increase borrowing capacity under Australian serviceability models. The exact uplift depends on your overall income, debts, loan term and the lender’s assessment rate. A broker can model different scenarios using your actual numbers.

How add‑backs and normalising adjustments can lift your borrowing

Normalising adjustments (add‑backs) let lenders use a higher income than your taxable profit by reversing non‑cash, one‑off and certain discretionary expenses. Used correctly, they can materially increase your assessed income and borrowing capacity without changing your tax returns.

Key Takeaway

Normalising adjustments, or add-backs, increase a borrower’s assessed income by reversing non-cash, one-off, or discretionary expenses in their financials, such as depreciation, certain interest, and abnormal costs. In Australia, this can lift usable income by $30,000–$60,000 a year for some self-employed borrowers, significantly boosting borrowing capacity under APRA’s 3% serviceability buffer. Working with an accountant and broker to identify lender-acceptable add-backs is a practical step borrowers can take before applying.

If you're self-employed, the money sitting in your business transaction account can actually help you buy a house. Business owners often leave heavy cash in their operating accounts for liquidity. Standard business lenders ignore this, but we utilise specialist policies that allow your business account balances to offset or support your personal mortgage application.

How add‑backs and normalising adjustments can lift your borrowing

Normalising adjustments (or “add‑backs”) are the adjustments lenders make to your tax returns to work out your real, sustainable income for a home or business loan. Instead of just using taxable profit, they add back certain non‑cash, one‑off or clearly discretionary expenses. Done properly, this can materially increase your assessed income – and your borrowing capacity – without changing your lodged returns.

Business financial statements with expenses highlighted as add-backs Identifying non-cash and one-off expenses is the first step in calculating normalising adjustments.

What are normalising adjustments – and why do lenders use them?

Normalising adjustments are corrections that turn your tax‑effective numbers into bank‑friendly numbers. The goal is to show what your income would look like in a normal year, if you stripped out:

Non‑cash accounting entries (like depreciation).
One‑off or abnormal expenses.
Some owner decisions (like voluntary extra super).

Tax planning vs borrowing power

Tax law pushes you to minimise taxable income. Lenders want evidence you can comfortably repay a loan, even with APRA’s ~3% serviceability buffer on top of the actual interest rate.

That tension is why aggressive tax minimisation can hurt borrowing power, sometimes more than the tax saved (see /insights/home-loans-high-income-self-employed-professionals). Normalising adjustments help bridge the gap without rewriting tax returns.

Where normalising adjustments appear

For self‑employed and small business owners, add‑backs are typically made to:

Company or trust financial statements.
Your personal tax return (particularly rental schedules and business income).

Lenders start from your net profit (or taxable income) then add back eligible items to arrive at assessable income. Each lender has a policy list of what they will and won’t accept.

Common add‑backs lenders may accept in Australia

Every lender is different, but these categories are widely recognised as potential add‑backs for self‑employed borrowers. ### 1. Non‑cash expenses These don’t leave your bank account, so they don’t affect your real‑world ability to repay: - Depreciation and amortisation – particularly on equipment, vehicles, fit‑outs and intangibles. - Book provisions – doubtful debts, some provisions for leave or warranties (case‑by‑case). Lenders often add these back in full, but may exclude accelerated write‑offs if they think the spending is ongoing. ### 2. Certain interest and finance costs Lenders don’t want to…

Frequently asked questions

Normalising adjustments are changes a lender makes to your tax returns to estimate your real, sustainable income. They typically add back non-cash items like depreciation, clearly one-off expenses and some discretionary owner costs. The aim is to show what your income looks like in a normal year, not just what appears as taxable profit.

Common add-backs include depreciation and amortisation, some interest on debts being refinanced, genuinely one-off legal or consultancy costs, and in some cases voluntary extra super or above-market director salaries. Each lender has its own rules, and they’ll want documentation to prove the expense is non-recurring or discretionary.

Generally no. Personal drawings and day-to-day living expenses reflect your real lifestyle cost, which lenders factor in using bank statements and benchmarks like HEM. While you can explain unusual spikes in spending, they are not treated as add-backs to increase income. Lenders care about what you need to live, not just what you report for tax.

No. Normalising adjustments are for lender assessment only and do not change your lodged tax returns or tax payable. They are a separate calculation used by banks to estimate serviceability. You should not amend returns just to chase a higher loan without tax and credit advice, as it can create ATO and lender concerns.
