## What’s changing?
- The **Excise Tariff (Fuel Duty Temporary Reduction) Determination 2026** came into force **1 April 2026** under the *Excise Tariff Act 1921*. ([legislation.gov.au](https://www.legislation.gov.au/F2026L00411/asmade?utm_source=openai))
- This measure **temporarily reduces fuel excise and excise-equivalent customs duties** on certain fuels (including petrol and diesel) for the period **1 April 2026 to 30 June 2026**. ([pwc.com.au](https://www.pwc.com.au/tax/monthly-tax-updates/may-2026.html?utm_source=openai))
## Who benefits—and how
- **Businesses with fuel-intensive operations** (transport, agriculture, freight) will see lower input costs during this period. Savings may be passed through or improve margins.
- **Individuals**, especially commuters, may observe reduced fuel prices (depending on retailer mark-ups). Budget accordingly.
## Key Implications & Considerations
| Concern | What to watch out for |
|---|---|
| **Accounting & cash flow** | Businesses should note that fuel excise is part of cost structure; temporary changes require adjusting cost forecasts and budgeting. |
| **Compliance in invoicing & records** | Ensure invoices and internal records reflect the lower excise; mismatches could cause audit issues. |
| **Duration & reversal** | The relief is **not permanent**; expect pre-30 June 2026 rates thereafter. Plan accordingly for the reversion. |
| **Tax credits / deductions** | Fuel excise paid is part of input costs: reductions will flow through cost of sales, cost base of business assets or stock. Tax deductions Claim appropriately. |
## Practical Example
A transport firm that over three months consumes **100,000 L of diesel**, previously paying say **cents per litre tax** at full rate, will enjoy excise relief across that volume. If the excise rate is cut by $0.30 per litre, this equates to **AU$30,000** in savings over the quarter. But when the excise rate returns to prior levels after 30 June, the firm must wrap this phase into its 2026-27 forecasts.
## Tips to make the most of it
1. **Track fuel usage closely for April-June 2026** and record savings per fuel type.
2. **Negotiate fuel supply contracts** referencing the temporary rate; some suppliers may pass on savings.
3. **Plan maintenance or equipment replacement** that requires fuel-use during the rebate period when savings are greatest.
4. **Review tax positions post-period**, ensuring reduced excise reflected when claiming deductions or in cost of goods sold.
5. **Model forward costs** to plan for the return to higher duty after 30 June 2026.
This short-term relief provides breathing room—though businesses and individuals should use the window wisely to reap benefits and prepare for the reversal.
