Handing down his fifth budget, Treasurer Jim Chalmers faced a familiar choice: rely on temporary measures that soften short term pressures or undertake the more difficult task of tax reform to shape investment, productivity, and future living standards. This year, he chose to go hard on budget reform in the hope of strengthening the country’s tax system and making it fairer.

Working Australians have been put front and centre, with the Working Australian Tax Offset (WATO) and a range of cost-of-living relief measures targeting healthcare, housing investment, and fuel security. Long-running debates about negative gearing and the capital gains tax discount have been revisited, raising a raft of new considerations for both foreign and local investors.

Measures that shake up the R&D Tax Incentive were not on the radar until budget night but will have a significant impact on the country’s innovation agenda, particularly for start-up and early-stage companies.

The changes to capital gains tax, the taxation of trusts, and to a lesser extent, curbs on negative gearing will be controversial. If enacted, they represent an investment-decision-shifting trio, pushing investors towards yield assets and a preference for holding them in private companies.

There is no question that tax reform has been long overdue in Australia, and BDO has been calling for it for years. Talk of rebalancing the system, cutting regulatory costs, and levelling the playing field will be welcomed by many, but in a budget billed as the most ambitious of this Government, could the discussion have been broadened to include changes to the taxation of consumption? As it is, we are left with continued heavy reliance on personal income tax and an increase in taxes on investment.

Reforming the treatment of tax losses for businesses and start-ups

The Government proposes to reintroduce the loss carry back offset and introduce a refundable tax offset for certain small business start-ups.

Currently, if a company incurs losses in an income year, it must wait until it returns to profitability before using the tax losses to reduce taxable income.

For tax years commencing on or after 1 July 2026, companies with an aggregated annual global turnover of less than $1 billion will be able to carry back revenue tax losses and offset them against tax paid up to two years earlier.

Expansion of dynamic PAYG instalment calculations and monthly payments

The Government has announced three measures to ‘simplify’ the tax system, helping businesses focus more on running their operations and less on tax compliance.

This includes the expansion of dynamic PAYG instalment calculations, monhtly payments as an option for SMEs and mandatory monthly reporting for non-compliant taxpayers.

R&D Tax Incentive reform

The Government has announced major reforms to the R&D Tax Incentive (RDTI), purportedly seeking to simplify the scheme and better target support for business research and development activities.

These changes will take effect from 1 July 2028 and will adjust offset rates as well as program delivery and eligibility criteria.

Expansion of venture capital tax incentives

The Government will expand venture capital tax incentives to better support early-stage and growth businesses.

From 1 July 2027, the asset size caps for investee businesses under the venture capital limited partnership (VCLP) and early-stage venture capital limited partnership (ESVCLP) programs will be increased.

Expanded ATO powers to address tax fraud

The Government will commit $86.3 million over four years from 1 July 2026, with ongoing funding of $9.7 million per annum from 2030–31, to implement Phase 2 of the Counter Fraud Strategy.

This will modernise fraud prevention and detection in the tax and superannuation systems, including strengthened real‑time ATO detection capabilities, enhanced individual protections, and expanded live monitoring of fraudulent account access involving tax agents, businesses, and high‑risk superannuation activities.
