Budget 2026-27 Tax Changes: What Property Investors and Self-Employed Borrowers Need to Know

Budget 2026–27 Tax Changes: The Immediate Impact on Property Borrowers

The Australian government's 2026–27 Budget has introduced significant tax system changes that are already being priced into lenders' credit assessments. For property investors and self-employed borrowers — two groups that form the core of the non-bank lending market — understanding these changes before your next loan application is essential.

The Budget measures include proposed amendments to negative gearing rules, adjustments to capital gains tax treatment for certain investment property holdings, and enhanced ATO reporting obligations for sole traders and small businesses. While some measures are still working through the Senate, lenders are not waiting for final legislation to adjust their approach.

How Major Banks Are Responding

Major banks are applying more conservative income assessments in anticipation of the tax changes. This typically means:

• Rental income from investment properties is being assessed with a higher assumed tax deduction, reducing net income figures used in serviceability calculations
• Business income for sole traders is being adjusted for new ATO reporting requirements, leading to more scrutiny of BAS statements and tax lodgements
• Borrowing capacity calculations may show lower figures for investor borrowers today compared with 12 months ago, even if actual income has not changed

According to the Australian Bureau of Statistics, the unemployment rate sits at 4.5% (April 2026) and CPI inflation is running at 4.2% annually — an environment where households are already stretched, making the additional friction from tax uncertainty especially damaging.

What Self-Employed Borrowers Need to Know

For self-employed borrowers, the enhanced ATO sole trader and small business reporting requirements create two important considerations:

First, ensure your BAS lodgements are current. Lenders using Alt Doc assessment will scrutinise your most recent 6–12 months of BAS statements more carefully than ever. Any gaps or late lodgements will raise questions.

Second, request a current accountant's letter. For complex income structures — including business owners who draw both a salary and dividends — an updated accountant's letter that accounts for the new tax environment will support your application more effectively than older documentation.

Non-Bank Lenders Offer a Different Assessment Framework

Non-bank lenders assess income differently from APRA-regulated banks. Where major banks apply standardised buffers and hypothetical post-reform tax scenarios, non-bank lenders focus on demonstrated repayment capacity based on your actual financial position today.

For investors, this means rental income assessed at actual market rates, investment property serviceability based on the property's own cash flow, and greater weight given to existing assets and equity.

For self-employed borrowers: Alt Doc loans accepted with BAS statements and accountant letters, assessment focused on business cash flow, and faster turnaround — typically weeks rather than months.

What MFAA Is Watching

The Mortgage and Finance Association of Australia (MFAA) has raised concerns about how the budget's broader tax changes affect the financial planning of mortgage brokers themselves. MFAA is actively engaging with the Senate to ensure that the practical credit market effects of the tax reform bill are understood by legislators.

Frequently Asked Questions

Will the Budget changes affect my existing mortgage?

For most existing borrowers, there is no immediate change to loan terms. However, if you plan to refinance or take out an additional loan, the new assessment framework will apply.

Can I still get an investment property loan if negative gearing rules change?

Yes. Lenders will still finance investment properties. The change affects how rental income is treated in your serviceability assessment — non-bank lenders tend to take a more flexible approach.

Do non-bank lenders consider the tax reform changes in their assessments?

Non-bank lenders focus on actual demonstrated income and current repayment capacity, rather than building in future hypothetical tax scenarios.
