$20K Small Business Instant Asset Write-Off Becomes Permanent — What Self-Employed Borrowers Need to Know

The $20,000 instant asset write-off for small businesses has been confirmed as a permanent feature of Australia's tax system in the 2026-27 Federal Budget, ending years of annual extensions and last-minute renewals. For self-employed business owners, this is welcome certainty — but it comes with an important cash flow caveat that borrowers should understand.

What the Instant Asset Write-Off Means

Under the scheme, eligible small businesses with an aggregated turnover under $10 million can immediately deduct the full cost of assets costing less than $20,000, rather than depreciating them over several years. Qualifying assets include tools, equipment, vehicles and business technology.

Making the scheme permanent removes the uncertainty that has forced many small business owners to rush year-end purchases or delay investment decisions. For businesses that regularly invest in capital equipment, this is a genuine planning benefit.

The Cash Flow Catch: PAYG Instalment Changes

However, the Budget also proposes updates to PAYG instalment calculations that may affect small business cash flow. Changes to how instalments are indexed could see some business owners making larger quarterly tax payments, partially offsetting the write-off benefit. Business owners should model the net cash flow impact before making major purchase decisions.

What This Means for Self-Employed Borrowers

For self-employed Australians seeking home loans, the permanent write-off creates both opportunity and complexity. More aggressive asset write-offs reduce taxable income — which is how the ATO measures income for full-doc loan applications. This can make major bank approval more difficult, even when the business is cash-flow positive.

This is precisely where Alt Doc loans play a critical role. MPFG Capital's Alt Doc loan products assess income based on BAS statements, accountant-prepared income statements or 12 months of business bank statements — not purely on tax return figures. This means a self-employed borrower can demonstrate genuine income even if their taxable income appears low due to legitimate write-offs.

A Note on Accountant Letters

When a business owner takes advantage of the instant asset write-off, an experienced accountant letter can explain the non-recurring nature of the deductions to a lender, helping restore borrowing capacity in the eyes of a non-bank assessor. MPFG Capital's credit team routinely works with borrowers and their accountants to present the full picture of business income.
