Bought a New Ute or Machinery? Don't Let the Instant Asset Write-Off Kill Your Mortgage
The Australian Government's Instant Asset Write-Off (and subsequent temporary full expensing measures under Section 40-82 of the ITAA 1997) has been fantastic for trade cash flow. It encouraged thousands of tradies to upgrade to modern dual-cab utes, mini-excavators, diagnostic scanners, and heavy tool setups by deducting the entire purchase price immediately.
However, there is a hidden trap: if your business turned over $300,000 and you purchased $60,000 in equipment under instant write-off, your lodged taxable profit dropped from $120,000 down to $60,000. When you apply for a mortgage at a standard bank, they assess you as earning only $60,000 a year.
This is completely wrong. You bought an asset that will last for years; you didn't incur an ongoing $60,000 annual expense. Specialist non-bank lenders treat Section 40-82 deductions as one-off non-recurring capital outlays and add 100% of the deduction back to your borrowing power.

1. The Section 40-82 Tax Trap Explained
Under standard Australian tax law, capital assets are depreciated over their effective working lives (e.g., 5 to 8 years for motor vehicles and tools). Under the Instant Asset Write-Off, the entire deduction is taken in Year 1.
Because retail bank algorithms only read the net bottom-line taxable income from your tax return, they treat this one-off tax incentive as an ongoing operational cost, dramatically slashing your borrowing capacity.
2. How Specialist Underwriters Restore Section 40-82 Income
When submitting your loan application, your broker includes an Asset Purchase Schedule detailing:
- Tax Depreciation Schedule Line Items: Identifying exact Section 40-82 or temporary full expensing entries.
- Invoice of Asset Purchase: Proving the purchase was a one-off capital upgrade.
- Ongoing Cash Flow Evidence: Bank statements proving that trading revenue remained robust post-purchase.
3. Maximizing Borrowing While Retaining Tax Benefits
By using a specialist mortgage broker, you achieve the ultimate financial outcome: you keep your tax savings from the ATO while unlocking your full borrowing power with specialist lenders.
