The 2026 Australian tax year brings some important dates and rules you can’t afford to miss. From the standard tax return deadlines to the fringe benefits tax lodgment and new superannuation tax changes coming into effect, it’s crucial to stay on top of these to avoid penalties and optimise your tax position.
Key Tax Dates for 2026
For most Australians, the 2026 tax year runs from July 1, 2025, through to June 30, 2026. If you plan to lodge your individual tax return yourself, the deadline is October 31, 2026. That means you need to have all your income details, deductions, and receipts organised before then.
If you use a registered tax agent, you might get an extension on lodging your return. However, to qualify for this extension, you must register with your tax agent by October 31, 2026. Otherwise, the standard deadline applies. Tax agents typically have deadlines extending into May the following year, but it depends on when you engage them.
Businesses and other entities have different deadlines depending on their structure and whether they lodge activity statements or tax returns. For example, companies usually lodge their returns by the 15th day of the seventh month after the end of their financial year — often January 15, 2027, for the 2026 year.
Fringe benefits tax (FBT) is on a different cycle. The FBT year runs from April 1, 2025, to March 31, 2026. If you lodge your FBT return yourself, the deadline is May 21, 2026. If you use a tax agent, the deadline extends to June 25, 2026. It’s important to mark these dates as the ATO is strict about late lodgments, often imposing penalties or interest for delays.
Don’t forget other key dates like PAYG instalment notices, BAS lodgments, and super guarantee payments. These have their own schedules throughout the year, which vary depending on your business size and reporting cycle. Staying organised throughout the year makes meeting all tax deadlines manageable.
Fringe Benefits Tax (FBT) Deadlines and Changes
FBT is a tax employers pay on most benefits they provide to employees or their associates in place of salary or wages. Common fringe benefits include company cars, gym memberships, expense reimbursements, and even entertainment expenses.
Employers must lodge their FBT returns by May 21, 2026, if self-lodging, or by June 25, 2026, if using a tax agent. The ATO warns that common mistakes on FBT returns include lodging nil returns when benefits were actually provided or incorrectly reporting private versus business use of work vehicles. These errors can trigger audits or penalties, so it’s wise to keep detailed records and review your calculations carefully.
A major change for the 2025-26 FBT year is the end of the exemption for plug-in hybrid electric vehicles (PHEVs). Until March 31, 2025, employers could provide PHEVs for private use without incurring FBT. From April 1, 2025, this exemption no longer applies, meaning employers must now pay FBT on PHEVs used privately by employees.
The exemption still applies to zero-emission electric vehicles (EVs), which means there’s still a strong incentive to provide fully electric vehicles over hybrids. Employers with novated leases involving PHEVs need to pay close attention to timing and eligibility rules to ensure correct FBT treatment. Novated leases are popular because they bundle salary packaging with vehicle expenses, but the tax rules have tightened around PHEVs.
It’s also worth noting that FBT is calculated on the taxable value of the fringe benefits provided, which can include factors like the cost price of vehicles, operating costs, and the amount of private use. Employers should review their FBT calculations carefully to avoid underreporting.
Superannuation Tax Changes Starting July 1, 2026
New superannuation tax rules kicking in from July 1, 2026, introduce higher tax rates on earnings for super balances above certain thresholds. These changes affect everyone with more than $3 million in total super savings, including those with self-managed super funds (SMSFs), retail funds, industry funds, and pension accounts.
Under these Division 296 tax laws, earnings on super balances between $3 million and $10 million will be taxed at 30%. For amounts exceeding $10 million, the tax rate rises to 40%. This is a big shift from the current standard 15% tax rate on super fund earnings and is designed to limit the tax concessions available to very high super balances.
Couples need to be aware that the tax applies to combined super balances. So, if one partner has $2 million and the other $1.5 million, the $500,000 excess above $3 million could be subject to the higher rates. Planning super contributions, pension withdrawals, and investment strategies will be essential to manage potential tax impacts.
SMSF owners should note they have an opportunity to reset the capital gains tax cost base on their assets as of July 1, 2026. This reset means the fund’s investments will be treated as if they were acquired on that date, potentially reducing future capital gains tax liabilities. However, the reset only applies to assets held at that date, so timing asset sales and purchases before July 1, 2026, can be a useful strategy.
The government has provided guidance indicating that these tax changes won't apply to the superannuation death benefit pensions paid to dependants on death, preserving some protections for families.
It’s also key to remember that these changes apply to fund earnings, not contributions or withdrawals directly. So, how your super fund invests your money could become even more important to minimise tax hit. Fund members should stay informed about how their super funds plan to respond to these changes.
The 2026 Australian tax year has clear deadlines that everyone should keep in mind. Whether it's lodging your income tax return by October 31, submitting your fringe benefits tax return by May 21, or preparing for the superannuation tax changes starting July 1, 2026, staying informed and organised is critical to avoid penalties and manage your tax position effectively.
