2026-27 Federal Budget: The Trust & Small Business Survival Guide to the 30% Minimum Tax

While the 2026-27 Federal Budget introduced significant changes for individual taxpayers, the most complex technical updates are reserved for those operating through private structures. For business owners and families utilizing discretionary trusts, the budget papers delivered a clear message: the era of flexible income splitting is transitioning into a new period of strict integrity and minimum tax floors.

As an accountant or business owner, navigating these “lines in the sand” requires a shift from traditional annual tax planning to long-term structural strategy. With a new 30% minimum tax on the horizon and unprecedented restructuring relief, the decisions made between now and 2028 will define the future profitability of your enterprise. In this guide, we dive into the technical mechanics of the trust overhaul and the specific support measures designed for the Australian small business sector.

The End of Income Splitting: The 30% Minimum Trust Tax

For decades, discretionary trusts have been the gold standard for tax planning because they allowed “income splitting.” This allowed a business owner to distribute profits to family members in lower tax brackets (such as adult children or a non-working spouse), significantly reducing the family’s overall tax bill.

The New Fact (Starting 1 July 2028): The Budget papers confirm that from 1 July 2028, a minimum 30% tax will be applied to all taxable income within a discretionary trust.

• How it Works: The Trustee is now responsible for paying a minimum of 30% tax on the trust’s profit before it is distributed to beneficiaries.
• The Non-Refundable Credit: When a family member receives a distribution, they get a tax credit for the 30% already paid by the trust.
• The “Low-Earner” Trap: This is the most critical change. If you distribute money to a family member whose personal tax rate is lower than 30%, they cannot claim a refund for the difference. The extra tax is simply lost to the ATO.

The Result: The tax benefit of distributing income to anyone earning less than approximately $45,000 (where the 15% and 30% tax brackets usually sit) is effectively wiped out.

Why the 30% Rate Matters for Your Cash Flow

This change isn’t just about the final tax bill; it’s about business cash flow. Under the old rules, many businesses distributed profits on paper and managed the tax at the individual level.

Under the new 2026 Budget rules, the Trust must have the cash ready to pay the 30% minimum tax upfront. For a business making $200,000 in profit, that is a $60,000 tax obligation that must be managed by the Trustee.

Example: The “Old Way” vs. The “New Way”

• The Scenario: The ABC Family Trust makes $100,000 profit. The Trustee distributes $45,000 to a spouse with no other income and $55,000 to the business owner.
• Before the Reform: The spouse would pay very little tax (due to the tax-free threshold), and the family would keep a large portion of that $45,000.
• After 1 July 2028: The Trust must pay $30,000 tax (30% of $100,000) immediately. Even though the spouse is in a low tax bracket, the family cannot get a refund of that 30% “pre-paid” tax. The “effective” tax rate for the whole family is now pushed up to at least 30%, regardless of who receives the money.

The “Trading Trust” Dilemma: A 5% Hidden Penalty

If you currently operate your business through a discretionary trust, the 2026 Budget has introduced a technical “valuation gap” that could cost you thousands. While Base Rate Entity (BRE) companies still enjoy a 25% tax rate on trading income, discretionary trusts will be subject to a 30% minimum tax floor from 1 July 2028. This means that by simply staying in a trust structure, your business is effectively paying a 5% “tax penalty” on every dollar of profit you retain for growth. To stay competitive and maintain that 25% edge, the structural decision to transition from a trust to a company is no longer just about asset protection—it is a mathematical necessity for your bottom line.

The “Restructuring” Lifeline: Moving from Trust to Company

The government recognizes that the new 30% minimum tax makes discretionary trusts less viable for many trading businesses. To prevent businesses from being “trapped” in an inefficient structure, the Budget provides a specific three-year window for change.

The Fact (1 July 2027 – 30 June 2030): The 2026 Budget expands “Rollover Relief” for small business entities. This allows you to transfer your business assets from a Discretionary Trust into a Company structure without triggering immediate Capital Gains Tax (CGT) or Stamp Duty penalties.

Technical Warning: Is This the End of the “Bucket Company”?

The 2026 Budget explicitly targets Corporate Beneficiaries (commonly known as Bucket Companies). Under the new rules starting 1 July 2028, companies receiving trust distributions will be denied any credit for the 30% tax paid by the Trustee. This creates a severe double-taxation penalty, potentially pushing the effective tax rate on those profits above 50% once they reach the company. This measure is designed to eliminate the incentive to store wealth in corporate shells, making the upcoming three-year restructuring window the most important planning period for family groups in a generation.

Small Business Cash Flow: Loss Carry Back

To support businesses through economic cycles, the Budget has reintroduced and modernized the Loss Carry Back measure.

The Fact (Starting 1 July 2026): If your business operates as a company and records a tax loss, you no longer have to wait for future profits to get a tax benefit. You can apply that loss against profits made in the previous two years.

• How it works: If you paid tax in 2025 but make a loss in 2026, you can “carry back” that loss and receive a cash refund from the ATO for the tax you already paid. This provides an immediate cash injection when your business needs it most.

Making the $20,000 Instant Asset Write-off Permanent

One of the most practical “wins” in the 2026 Budget is the certainty regarding equipment purchases. The $20,000 Instant Asset Write-off, which previously required annual extensions, is now a permanent feature of the tax system for businesses with turnover under $10 million.

• The Rule: You can instantly deduct the full cost of any eligible asset worth less than $20,000 in the year it is first used or installed.
• Pro-Growth Tip: This isn’t limited to one asset. You can claim multiple items (e.g., a $15,000 van and a $4,000 equipment upgrade) as long as each individual item is under the $20,000 threshold.

What Next 

The 2026-27 Federal Budget has sent a clear message to the Australian business community: the era of passive income splitting is ending, and the era of structural efficiency is beginning. While the 30% Trust Tax is a challenge, the permanent write-offs and restructuring relief provide a clear roadmap for those willing to adapt.

Frequently Asked Questions (FAQ)

• Will the 30% minimum tax apply to all trusts? No. The Budget papers specifically exclude fixed trusts, widely held trusts, complying superannuation funds, charitable trusts, and testamentary trusts that existed as of 12 May 2026. The measure is primarily targeted at discretionary “family” trusts. 
• What happens if my family members are in a tax bracket lower than 30%? From 1 July 2028, the Trustee pays the 30% tax upfront. While beneficiaries receive a credit for this tax, it is non-refundable. If their personal tax rate is only 15%, they cannot claim the 15% difference back, effectively “trapping” the tax at the higher rate. 
• Can I avoid the 30% tax by using a Bucket Company? The Budget has effectively closed this loophole. Corporate beneficiaries will no longer receive a credit for the tax paid by the Trustee. This leads to a “double-taxation” scenario, making bucket companies an inefficient way to store trust wealth from 2028 onwards. 
• Is there any relief for primary production income? Yes. Primary production income earned within a discretionary trust is specifically exempted from the 30% minimum tax rule, providing continued support for Australian farming families.
