Federal Budget May 2026: What to Expect and How to Prepare Your Finances

Budget Night Is Coming: Why This One Matters More Than Most

Treasurer Jim Chalmers will deliver the 2026-27 federal budget on Monday, 12 May 2026, and this one carries more weight than any budget since the pandemic emergency measures of 2020.

The Albanese government faces an extraordinary set of competing pressures. The Iran conflict has triggered a global energy shock that is pushing petrol prices past $2.50 per litre, the RBA has hiked the cash rate to 4.10% with another increase likely in May, inflation could reach the “mid to high fours” according to Chalmers himself, and the government went to the 2025 election promising cost-of-living relief it now needs to deliver in a deteriorating fiscal environment.

Add to that the government’s signalled intention to reform the capital gains tax discount and negative gearing, still the most politically charged tax debate in Australian politics, and you have a budget that could reshape household finances for years to come.

Here is what we know, what we expect, and what you should be doing to prepare.

The Economic Backdrop: Why the Budget Is Under Pressure

Inflation Is Rising Again

Just when it seemed like inflation was under control, the Iran conflict has thrown a spanner in the works. The Consumer Price Index was tracking at 3.8% annually in early 2026, but Treasurer Chalmers has warned it could reach the “mid to high fours” as the energy shock flows through the economy.

The RBA’s inflation target is 2-3%. Being potentially double that level forces both the RBA and the government into difficult positions:

• The RBA has responded with rate hikes (cash rate now 4.10%, with 4.35% widely expected by May)
• The government faces pressure to provide cost-of-living relief, but stimulus spending could worsen inflation
• Budget revenue from higher commodity prices may partially offset higher spending, but the net fiscal impact is uncertain

The Budget’s Fiscal Position

The government’s fiscal position has deteriorated since the 2025 election. Key factors:

The Australian Financial Review has reported that the government faces a genuine dilemma between budget repair (reducing the deficit to build fiscal buffers) and cost-of-living relief (which costs money). Chalmers has reportedly been studying the Hawke-Keating era approach of structural reform alongside fiscal discipline, suggesting the budget may contain both spending and savings measures.

What’s Already Locked In for 1 July 2026

Several significant policy changes are already legislated and will take effect from 1 July 2026 regardless of what the budget contains:

Tax Rate Cut

The income tax rate for the $18,201-$45,000 bracket drops from 16% to 15%. This delivers:

A further reduction to 14% is planned for 1 July 2027. These cuts were legislated in the 2025 budget and are separate from any new measures announced in May 2026.

Division 296 Super Tax

From 1 July 2026, individuals with total super balances above $3 million will pay an additional 15% tax on earnings attributable to the amount above $3 million. This brings the total tax rate on those earnings to 30% (up from the standard 15% super tax rate).

Key details:

• The tax applies to “notional earnings,” calculated as the increase in your total super balance over the financial year, adjusted for contributions and withdrawals
• For the first year (2026-27), a transitional rule means the calculation is based solely on the balance at 30 June 2027
• Unrealised capital gains are included in the calculation, which has been one of the most controversial aspects
• A higher threshold of $10 million applies before a further tier kicks in

Individuals approaching the $3 million threshold should be reviewing their super strategy with a financial adviser before 30 June 2026.

Superannuation Guarantee Increase

The SG rate increases from 12% to 12.5% from 1 July 2026, on its way to 13% in the 2028-29 financial year. For employers, this means higher payroll costs. For employees, it means more flowing into super.

On a salary of $100,000, the increase from 12% to 12.5% means an extra $500 per year going into super. Over a 30-year career, with investment returns, that additional 0.5% could add $30,000-$50,000 to a retirement balance.

Payday Super

From 1 July 2026, employers must pay superannuation at the same time as wages (or within seven days), replacing the current quarterly payment cycle. This is a major change for small businesses that have historically managed cash flow by paying super quarterly.

The intent is to prevent the accumulation of unpaid super (estimated at $5.1 billion per year) and ensure workers’ super is invested earlier. But for small businesses already under cash flow pressure, the transition to more frequent super payments adds another operational burden.

What the Budget Might Contain: The Speculation

Capital Gains Tax Discount Reform

This is the big one. The 50% CGT discount, introduced by the Howard government in 1999, allows individuals who hold an asset for more than 12 months to include only half of any capital gain in their assessable income. For a top-rate taxpayer, this means the effective tax rate on a long-term capital gain is 23.5% rather than 47%.

A Senate Economics References Committee inquiry, with its report endorsed by two Labor senators, found that:

• The discount is “poorly targeted” and disproportionately benefits high-income earners
• It distorts investment toward housing and away from productive assets
• It contributes to the affordability gap between investors and first-home buyers
• It costs the budget roughly $10-12 billion per year in foregone revenue

Treasurer Chalmers has pointedly refused to rule out changes, telling reporters the government would “consider the findings carefully.”

What might change:

If the government does proceed with CGT reform, it would almost certainly apply prospectively (to assets acquired after a specified date) rather than retrospectively. This is both politically necessary and consistent with how the original discount was introduced.

What investors should consider:

• If you have been planning to sell an investment property or significant share holdings, the current 50% discount is guaranteed. A change, if announced, would likely apply to future acquisitions.
• Do not panic sell. Even a reduced CGT discount does not make investing unprofitable, it just changes the after-tax return.
• The discount applies to all capital assets (shares, ETFs, property, crypto), not just property. Any reform would affect all asset classes.

Negative Gearing Changes

Negative gearing (claiming tax deductions for investment property losses against other income) is often discussed alongside CGT reform. The Labor government’s pre-election position was to limit negative gearing to new housing only, which would mean investors in existing properties could only offset losses against future rental income or capital gains on that property, not against salary income.

If implemented alongside a reduced CGT discount, the combined impact on property investors would be significant:

These are estimates only and would depend on the specific design of any reforms.

Cost-of-Living Measures

Given the economic environment, the budget will almost certainly include cost-of-living measures. Expected announcements include:

Energy bill relief: The current $300 household energy rebate (delivered as quarterly $75 credits on electricity bills) expires on 30 June 2026. An extension or replacement is widely expected, potentially with a higher amount to reflect the energy price shock from the Iran conflict.

Fuel excise: With petrol prices above $2.50 per litre, there will be pressure to temporarily reduce the fuel excise (currently 51 cents per litre, indexed to CPI). The Morrison government temporarily halved the excise in 2022 during a previous fuel price spike. The Albanese government may consider a similar measure, though it is expensive (costing the budget roughly $3 billion for every six months of halving).

Rent assistance: Commonwealth Rent Assistance has been increased twice since 2023. A further increase is possible, given rents continue to rise faster than wages in most capital cities.

Pharmaceutical Benefits Scheme: Further reductions to PBS co-payments or expansion of the list of subsidised medicines are possible. The government has already reduced the general PBS co-payment and lowered the safety net threshold.

Housing Policy

Housing affordability is a top priority for the Albanese government, and the budget is expected to include significant housing announcements:

• Additional funding for social and affordable housing through the Housing Australia Future Fund
• Planning reform incentives to encourage states to approve more housing
• Potential expansion of the Help to Buy shared equity scheme or first home buyer support
• Possible announcements on build-to-rent incentives to encourage institutional investment in rental housing

The government’s target of 1.2 million new homes by 2029 requires a dramatic increase in building activity. The budget may include measures to address construction sector capacity constraints, including skilled migration and training programs.

Small Business Measures

Given the insolvency crisis hitting small businesses (see our separate article on that topic), the budget may include:

• Extension of the instant asset write-off for small businesses (currently $20,000 threshold)
• Energy cost relief targeted at small businesses
• Possible expansion of the Small Business Restructuring debt threshold
• Additional ATO payment plan flexibility for businesses affected by the energy shock

What You Should Do Before Budget Night

1. Review Your Investment Portfolio

If CGT changes are announced, they will almost certainly apply to future acquisitions. But the uncertainty itself is a reason to review your portfolio:

• Are there positions you have been meaning to sell? The current 50% CGT discount is locked in for existing holdings.
• Do you have unrealised capital losses that could be crystallised to offset gains?
• Is your portfolio appropriately diversified for the current economic environment?

2. Maximise Super Contributions Before 30 June 2026

The concessional (before-tax) super contribution cap for 2025-26 is $30,000. If you have not maximised your contributions, you have until 30 June to do so. Concessional contributions include:

• Employer SG contributions (12% of ordinary time earnings)
• Salary sacrifice contributions
• Personal deductible contributions

For a worker on $100,000 earning 12% SG ($12,000), there is $18,000 of unused concessional cap that could be contributed via salary sacrifice or personal deductible contributions. At a marginal tax rate of 30% (plus Medicare levy), a $18,000 concessional contribution saves approximately $2,700 in tax.

If you have unused concessional cap amounts from previous years (the “carry-forward” rule applies if your total super balance was under $500,000 at the prior 30 June), you may be able to contribute even more.

Non-concessional (after-tax) contributions are capped at $120,000 per year (or $360,000 using the bring-forward rule over three years) for those with total super balances under $1.9 million.

3. Check Your Tax Withholding

The tax rate cut from 16% to 15% on the $18,201-$45,000 bracket takes effect from 1 July 2026. Your employer should automatically adjust PAYG withholding from that date. But if you have multiple income sources or complex tax affairs, check that your withholding is appropriate to avoid a large tax bill or unnecessarily large refund.

4. Build an Emergency Fund

Regardless of what the budget contains, the economic environment is uncertain. Rising interest rates, potential job losses in affected sectors, and higher living costs all argue for having a cash buffer:

• Minimum: 3 months of essential expenses
• Recommended: 6 months of essential expenses
• If self-employed or in a vulnerable industry: 9-12 months

High-interest savings accounts are currently paying 5.0-5.5% at several institutions (including ING, Macquarie, and Ubank), making cash savings more attractive than they have been in years.

5. Review Your Mortgage

If you are on a variable rate mortgage, run the numbers on what a further 0.25% rate increase (taking the cash rate to 4.35%) would mean for your repayments:

Based on a 30-year principal and interest loan at variable rate (cash rate + 2.0% margin). Your actual rate will vary.

If your budget is tight, now is the time to:

• Compare your current rate against market offers (refinancing could save 0.30-0.50%)
• Consider fixing a portion of your loan if you expect further rate rises
• Build a buffer in your offset account
• Contact your lender proactively if you are concerned about affordability

6. Get Professional Advice

The intersection of potential tax changes, rising interest rates, super reforms, and investment decisions creates a complex environment where professional advice can deliver real value. A financial adviser or accountant can help you:

• Model the impact of potential CGT changes on your investment strategy
• Optimise your super contributions before the end of financial year
• Review your investment portfolio for the current economic climate
• Ensure your tax affairs are in order ahead of any policy changes

Budget Night: What to Watch For

When the budget is delivered on 12 May 2026, here are the key numbers and announcements to watch:

1. The deficit/surplus figure for 2026-27 and the forward estimates
2. Any changes to the CGT discount or negative gearing rules, including effective dates
3. Cost-of-living measures: energy rebates, fuel excise, rent assistance
4. Super changes beyond what is already legislated
5. Housing policy announcements and funding commitments
6. Small business support measures
7. Defence spending (likely to increase significantly given geopolitical tensions)
8. Infrastructure spending and its impact on job creation

Budget papers are typically released at 7:30 PM AEST on budget night, with the Treasurer’s speech to Parliament starting shortly after. All major media outlets provide live coverage and analysis.

The Bigger Picture

This budget comes at a critical juncture for the Australian economy. The government must balance cost-of-living relief against fiscal responsibility, structural reform against political risk, and short-term pressures against long-term economic health.

For households, the message is the same regardless of what the budget contains: focus on what you can control. Build your emergency fund, review your spending, maximise your super, and ensure your investment strategy aligns with your goals and risk tolerance. Policy changes will come and go, but sound financial fundamentals endure.
