The Biggest Tax Shake-Up in 25 Years: What Small Business Owners Need to Know
Do you remember, on the night of 12 May 2026, Treasurer Jim Chalmers stood up and delivered what he called “the most important and ambitious Budget in decades.”
The 2026–27 Federal Budget contains the most sweeping structural tax reforms Australia has seen since the Howard government introduced the GST. The 50% CGT discount that investors have relied on since 1999 is being replaced.
And all of this lands on top of payday super, ATO debt that’s no longer tax deductible, and a new income tax cut starting 1 July 2026.
If you run a small business in Australia, especially if you hold property, operate through a trust, or have been sitting on ATO debt, this budget touches you directly.
Since Budget night, many business owners have been asking how these changes may affect their tax position, investment structure, and EOFY planning. Business owners in Melbourne and across the country are asking the same things: “How does this hit me? What should I do? And how fast do I need to move?
This guide breaks down every major announcement through the lens of a small business owner.
Here’s the complete summary of what the Chalmers budget 2026 announcements mean for small business owners and investors:
Good news for small business:
Changes that need urgent planning:
The budget is layered and some changes are live now. Others will kick in 2027 and 2028. But the planning needs to start today.
Let’s be straight about the economic backdrop.
This budget didn’t land in a stable environment. CPA Australia’s budget analysis notes that Treasurer Chalmers acknowledged Australia is facing its “fifth economic shock in less than 20 years.” Global oil disruption, elevated inflation, rising borrowing costs and softening growth are pressing hard on every business.
The budget deficit sits at $28.3 billion for 2025–26. It is an improvement of $8.5 billion on the December MYEFO forecast, according to Deloitte’s budget analysis. But the government is raising significant new revenue to fund cost-of-living measures and defence spending and much of that revenue is coming from investors, trust holders, and property owners.
For small business owners, the core tension is this:
The government is simultaneously offering you tax relief through write-offs and carry-backs while fundamentally restructuring how investment income through trusts and property is taxed. The challenge is understanding which measures create opportunities and which ones require urgent planning.
Understanding which applies to you and in what order is the most valuable thing you can do this side of 30 June.
The federal budget 2026 Australia was handed down by Treasurer Jim Chalmers on 12 May 2026. It is the first budget delivered after Labor’s re-election at the 2025 federal election, and the fifth Chalmers budget overall.
As PwC’s federal budget analysis notes, this was “a tax and superannuation agenda that is more ambitious in scope than any single Budget delivered in recent years.”
The headline is simple: the government is rebalancing the tax system away from asset income and toward labour income. Chalmers framed it explicitly as addressing a system that is “more generous to assets than it is to labour.”
Three measures sit at the structural core:
Alongside those sit meaningful small business incentives – the permanent instant asset write-off, loss carry-back, and monthly PAYG flexibility. And layered over everything is payday super, which hits employers from 1 July 2026 regardless of what else is in the budget.
The budget forecasts an underlying cash deficit of $31.5 billion for 2026–27, according to CPA Australia, which is $2.8 billion lower than last year, as the government balances the books with new tax revenue against spending pressures in defence, energy security, and social services.
This isn’t a budget where you read about one change and move on.
The federal budget 2026 small business impact stacks up across multiple categories like your investment property, your trust structure, your payroll obligations, your ATO debt position, and your equipment purchasing decisions. For many small business owners in Melbourne and across Australia, all of them apply at once.
The numbers that capture the scale:
The government’s stated goal is intergenerational equity. The practical effect is that the investment and structuring strategies that worked for the last 25 years are being fundamentally redrawn.
CGT Discount Changes 2026: What Business Owners and Investors Need to Know
This is the one that’s landed with the most impact, and for good reason.
Since 1999, Australians who held assets for more than 12 months like property, shares, business interests could discount their capital gain by 50% before tax. It became the bedrock of investment strategy for an entire generation of business owners and property investors.
From 1 July 2027, that’s over.
As confirmed in PwC’s analysis, the new framework works like this:
What’s protected:
What this means practically: If you’re planning to sell a significant asset like a business, an investment property, shares in a company and it will generate a large capital gain, the window to do that under the old 50% discount rules is *before 1 July 2027. That’s just over 13 months away. This needs to be on your tax planning agenda before EOFY 2026, not after.
As Ashurst’s budget analysis puts it: “For those members of the Ashurst tax team of a certain age, the 2026 Budget announcement contained some genuinely heart-palpitating shocks.”
The HOC Tax Planning team is already modelling CGT scenarios for clients with significant unrealised gains because the time to plan is now, not when the legislation is finalised.
Negative Gearing Changes 2026 Australia: What Property Investors Should Review
The negative gearing changes got the most media attention. The reality is more nuanced than the headlines suggested.
What actually changed, confirmed in the budget papers:
What’s grandfathered:
As Holding Redlich’s analysis notes, for small business owners with investment property portfolios, the intersection of CGT indexation, negative gearing restrictions, and trust tax rules creates compounding complexity that genuinely requires professional advice to navigate.
Key question for Melbourne property investors: If you’re planning to purchase a residential investment property after Budget night – the tax calculus has fundamentally changed. Properties bought through discretionary trusts are doubly affected (trust minimum tax from 2028 compounds the impact). This is a conversation you need to have with your adviser before signing any contracts.
Family Trust Tax Changes 2026: Why Business Owners Should Review Their Structure
Of all the changes in this budget, the 30% minimum tax on discretionary trusts may be the one that affects the largest number of small business owners in Australia and the one that’s least understood.
There are currently over 900,000 family trusts in Australia, according to the budget papers. A significant proportion of small business owners use discretionary trusts for income splitting, asset protection, and estate planning. The 2026–27 Federal Budget takes direct aim at that.
What the new rules say, per Corrs Chambers Westgarth’s analysis:
The rollover relief window:
As Morrows Advisory notes, “for many families and business owners, discretionary trusts form an important part of long-term wealth, succession, estate planning, asset protection planning and family investment structures.”
If you currently operate through a family trust distributing income to lower-income family members, holding investment property, or using a bucket company, this change reshapes your tax position from 2028. And the restructuring window to act opens in 2027 and closes in 2030.
This is the change most small business owners haven’t started thinking about yet. It’s the one that will cause the most urgent conversations in accounting offices across Melbourne over the next 18 months.
The HOC Business Advisory team is already working with clients to model the trust impact across income splitting, succession structures, and asset protection arrangements.
Not everything in the 2026–27 budget is a headwind. Let’s look at the genuine wins for small business owners.
If there’s one unambiguously good news item in this budget for small business owners, it’s this.
The $20,000 instant asset write-off is now permanent from 1 July 2026, for businesses with aggregated annual turnover under $10 million.
For years, this measure was renewed year-by-year, often at the last minute, often with uncertainty about whether it would continue. Small business owners couldn’t plan equipment purchases with confidence. That era is over.
What this means from 1 July 2026:
As Prospa notes in their budget analysis, “no more waiting for last-minute announcements; you can plan equipment purchases, invest in tech, or upgrade tools any time.”
For Melbourne small businesses thinking about new equipment, technology, fit-outs, or tools, the write-off is live and permanent. Plan accordingly.
The already-legislated income tax cut takes effect 1 July 2026 – the 16% personal income tax rate drops to 15%, falling again to 14% from 1 July 2027.
This has a meaningful flow-on effect for employers:
None of these directly reduce your payroll costs, but they ease cost-of-living pressure on your workforce, which matters in a tight labour market.
If your company has a tough year in 2026–27, you no longer have to just absorb the loss and wait.
The loss carry-back regime is reintroduced from the 2026–27 income year for companies with aggregated annual global turnover under $1 billion. Around 85,000 companies will benefit the majority of small businesses, per the PM’s budget announcement.
How it works:
This is a meaningful safety net for small business owners navigating a tough economic environment. It’s worth discussing with your HOC Tax Planning adviser to understand whether your structure qualifies and how to position it.
ATO Debt Interest Not Deductible: Why Business Owners Should Act Early
This one is already in effect and not enough business owners know about it.
From the 2025–26 income year, interest charges on ATO tax debts are no longer tax deductible for businesses.ATO interest charges can be costly, businesses. ATO interest charges can be costly and from 1 July 2025, affected GIC and SIC amounts are no longer deductible.
As WealthWorks flagged before the budget, “this is now one of the most expensive forms of business debt.” If you’re carrying COVID-era ATO debt or have tax payment arrangements in place, this change dramatically increases the real cost of carrying that debt.
The action item is simple but urgent: prioritise paying off ATO debt before 30 June 2026. Every dollar of ATO interest you incur from this income year is not deductible and costs you more in real terms than almost any other form of business finance.
Step-by-Step Federal Budget 2026 Action Plan for Small Business Owners
Here is your EOFY tax planning 2026 Australia action list, built for the specific realities of this budget.
Before making any decisions about assets, structures, or purchases, sit down with your adviser and map out exactly where you sit across four dimensions:
This mapping exercise is the foundation for everything else. The HOC Business Advisory team runs clients through exactly this kind of structured review.
If you hold an asset with a large unrealised capital gain and you were planning to sell it “eventually”, the window to sell under the 50% discount rules closes 30 June 2027.
Work with your accountant to:
This is particularly urgent for Melbourne property investors with established investment properties held in trusts because the negative gearing restriction and the trust minimum tax both apply on top of the CGT change.
If you use a discretionary trust, the 30% minimum tax doesn’t land until 1 July 2028. But the restructuring window opens 1 July 2027 and runs for only three years.
The restructure decision requires:
This is not a decision you can make the week before the rollover window closes. Start the conversation now.
Our SMSF and superannuation team is also across the trust-to-SMSF implications because for some clients, the restructured conversation leads directly to a review of how their SMSF fits into the picture.
Given that ATO interest is no longer deductible from this income year, the math on carrying ATO debt has changed. Paying it off is now a higher priority than it was 12 months ago.
Look at:
Your HOC tax adviser can run the numbers on whether accelerated ATO debt repayment makes sense before EOFY.
This one doesn’t wait for 2027 or 2028. Payday super starts 1 July 2026.
If you haven’t yet confirmed your payroll software is Payday Super-ready, transitioned off the Small Business Superannuation Clearing House, and modelled your new cash flow position, you are running out of time.
Our recent detailed guide to Payday Super covers the full picture. Read it and then act on it.
Now that the $20,000 instant asset write-off is permanent, the EOFY equipment purchasing rush is less critical than in prior years.
But if you have equipment purchases you’ve been deferring and you’re a business with turnover under $10 million there’s no reason to wait. Any eligible asset under $20,000 purchased and first used or installed from 1 July 2026 onwards is immediately deductible. No depreciation. No spreading the cost.
If your company had a tough 2026–27 or expects one, review eligibility for loss carry-back with your accountant.
The calculation involves:
Done right, this can generate a meaningful cash refund. Done wrong, it wastes time on an ineligible claim.
Common Federal Budget 2026 Myths Small Business Owners Should Avoid
Partly true. Incompletely understood.
Grandfathering protects your existing properties from the negative gearing restriction while you hold them. But when you sell them after 1 July 2027, the new CGT rules apply to gains accruing from that date. You’ll need a valuation as at 1 July 2027 to split the gain correctly.
And if your property sits inside a discretionary trust, the 30% minimum trust tax from 2028 also applies to the ongoing rental income, even for grandfathered properties.
The trust changes start in 2028. The rollover window opens in 2027. The planning needs to start now.
Restructuring a trust is not a quick exercise. It involves legal advice, accounting modelling, potential stamp duty implications, SMSF considerations, and estate planning reviews. Eighteen months goes quickly.
Completely false. The Division 152 small business CGT concessions are unchanged in this budget. If you’re selling your business and meet the eligibility criteria, those concessions still apply. Confirm your eligibility with your adviser, but don’t assume this door has closed.
Some of these measures still need to pass Parliament. But the planning can’t wait for legislative certainty.
These measures are subject to legislative passage, but business owners should begin modelling their exposure now so they are prepared if the reforms proceed as announced. Waiting for final legislation before starting your modelling means losing months of runway.
No. It was deductible. It isn’t now from the 2025–26 income year. If your business is carrying ATO debt and you haven’t factored this in, you’re underestimating your true cost of that debt.
The budget is structured across three distinct time horizons. Here’s the urgency map:
Act immediately – before 30 June 2026:
Act within 12 months – before 1 July 2027:
Act within 3 years – before 30 June 2030:
Every one of these horizons is shorter than it looks.

How HOC Helps Small Business Owners Respond to the 2026–27 Federal Budget
Hughes O’Dea Corredig (HOC) is a Melbourne accounting and wealth management firm that has been helping small business owners navigate tax law changes since 1978. We have seen budgets come and go. This is one of the genuinely big ones and it requires more than a quick read of the headlines.
Here’s where we specifically help right now:
From modelling CGT scenarios before 30 June 2027, to positioning loss carry-back claims, to managing the tax implications of payday super, our tax planning team translates Chalmers’ budget into a concrete plan for your specific business and investment situation. Not generic advice. Your numbers, your structure, your timeline.
If you hold super inside an SMSF or are considering restructuring out of a discretionary trust and exploring an SMSF’s role, our SMSF team can help review how superannuation, contribution timing, and structure decisions interact with the budget changes.
The payday super changes also affect SMSFs directly from ESA requirements to contribution timelines.
The structural questions this budget raises “should you stay in your trust?” Should you restructure? Is your business exit still tax-efficient under the new CGT rules? These are business strategy questions as much as tax questions. Our business advisory practice helps you think through the full picture, not just the immediate tax outcome.
Whether you’re in Essendon or anywhere in Australia, the HOC team delivers practical, no-jargon advice that ends with a clear plan.
What does the federal budget 2026 mean for small business owners? The budget delivers the $20,000 instant asset write-off permanently, reintroduces loss carry-back, and introduces income tax cuts from 1 July 2026. But it also replaces the 50% CGT discount (from 2027), restricts negative gearing on established residential property (from 2027), and introduces a 30% minimum tax on discretionary trusts (from 2028). The net impact depends entirely on your business structure and investment mix.
When do the CGT discount changes start? The CGT discount changes start 1 July 2027. Gains on assets sold before that date use existing 50% discount rules. Assets held across that date will have gains split i.e. 50% discount up to 30 June 2027, new indexation rules for gains from 1 July 2027 onwards. This makes valuation of assets on 1 July 2027 critically important.
How will CGT changes affect Melbourne property investors? Melbourne property investors with established investment properties face a combination of impacts: negative gearing on new purchases ring-fenced from 2027, CGT tax on gains from 2027 under the new indexation model, and if the property is in a discretionary trust, the 30% minimum trust tax from 2028 on rental income. Properties owned before Budget night are grandfathered for negative gearing but not for CGT on future gains.
What are the family trust tax changes 2026? From 1 July 2028, discretionary trusts will pay a 30% minimum tax on taxable income at the trustee level. Non-corporate beneficiaries get a non-refundable tax credit. Bucket company beneficiaries do not. A three-year rollover window from 1 July 2027 to 30 June 2030 allows restructuring without triggering income tax or CGT.
Is the instant asset write-off 2026 extended or is it now permanent? It is now permanently extended, no more annual renewals. From 1 July 2026, eligible businesses with turnover under $10 million can immediately deduct assets costing less than $20,000 each, indefinitely. This is confirmed in the budget papers.
What happens to ATO debt interest in 2026? ATO interest charges are no longer tax deductible from the 2025–26 income year. This is already in effect. ATO interest currently runs at approximately 11.38%, making it one of the most expensive forms of business debt. Paying it down before EOFY should be a priority.
What is EOFY tax planning for 2026 and why is it urgent this year? EOFY 2026 is more consequential than most years because: payday super starts 1 July 2026, income tax cuts take effect 1 July 2026, ATO debt interest non-deductibility is in effect, and the countdown to the 1 July 2027 CGT and negative gearing changes begins now. Positioning your income, expenses, and asset sale timing before 30 June 2026 matters more than in a typical year.
Does the budget affect my SMSF? The budget includes no direct changes to SMSF contribution caps or the Division 296 tax (which was already legislated). However, payday super changes affect employer contributions to SMSFs directly. The negative gearing changes do not apply to widely held trusts or super funds and SMSFs are excluded. Trust restructuring conversations may involve SMSF as a destination structure.

The 2026–27 Federal Budget is not one you read, nod at, and file away.
For Australian small business owners, particularly in Melbourne where investment property and trust structures are deeply embedded in how wealth is held, the combination of CGT discount changes, negative gearing restriction, family trust minimum tax, ATO debt non-deductibility, and payday super creates a genuinely complex picture that rewards early, careful planning.
Business owners who engage a trusted tax adviser early can make more informed decisions about modelling scenarios, reviewing structures, and planning before key deadlines.for modelling scenarios, reviewing structures, making timing decisions before 30 June, will have meaningful advantages over those who wait.
The good news is the window is still open. The federal budget 2026 Melbourne small business community has time to respond. But that time is finite, and several deadlines are closer than they look.
