Prepare for 30 June 2025: Tax and other changes you should know about

The lead up to the end of the financial year can be an extremely busy time for small businesses.  

It is important to take some time to familiarise yourself with key taxation and other financial measures that are changing on 1 July 2025. As always, check the ATO website for more information and consult your financial advisor where needed. 

Superannuation Guarantee increase 

From 1 July 2025, the Superannuation Guarantee (SG) rate increases from 11.5% to 12%. You will need to ensure your payroll systems are set to accommodate this change. For up to date information see here. 

Instant asset write-off 

The $20,000 instant asset write-off is legislated to conclude on June 30, 2025. Without new legislation, the threshold will revert to $1,000 from July 1, 2025. The Government has committed to extending the $20,000 threshold for the 2025–26 financial year, but this extension has not yet been legislated. Check for updates or seek advice on how this may affect your business. For up to date information see here. 

Non-deductibility of ATO Interest Charges 

Interest on overdue tax debts is no longer tax-deductible. This means any General Interest Charge (GIC) or Shortfall Interest Charge (SIC) applied to unpaid tax is now treated as a full business cost with no tax offset. For up to date information see here.  

Minimum wage increase 

The national minimum wage will increase from 1 July 2025. Changes to the minimum and award wages should be factored into payroll and budgeting for the year ahead. For up to date information see here. 

Right to disconnect 

Employees in small businesses (less than 15 employees) will have the right to refuse unreasonable work-related contact outside of their regular working hours, starting 26 August 2025. For up to date information see here. 

Pay as you go (PAYG) withholding 

While most withholding schedules and tax tables are unchanged, ensure you’re using the correct and up to date versions. For up to date information see here. 

Energy bill relief 

The Government has extended its small business energy bill relief through to 31 December 2025, offering up to $150 in rebates automatically applied to your account. For up to date information see here. 

Beware of scams 

Scammers are increasingly active around tax time. Be on the lookout for strange texts or emails from scammers impersonating a trusted government organisation and be sure to report any scam attempts you come across.
