Tax laws are subject to change, and it is essential to consult with a registered tax professional for personalized advice tailored to your specific circumstances. This guide should be used for informational purposes only and does not constitute professional tax advice.

Understanding the Australian Financial Year

Before diving into specific dates, it’s important to understand the Australian financial year. It runs from July 1st to June 30th. Therefore, the 2025 tax year refers to the period from July 1, 2024, to June 30, 2025. The deadlines outlined below generally relate to income earned during this period.

Key Tax Deadlines for Individuals in 2025

For individual taxpayers, the main focus revolves around lodging their income tax return. However, understanding payment obligations for items like PAYG (Pay As You Go) installments is also essential for those who may be required to pay them.

• July 1, 2024 – June 30, 2025: The period for which income is earned and expenses are incurred. Keep meticulous records of all income and deductible expenses throughout this period.

• July 1, 2025: The start of the tax return lodgement period. You can start preparing your tax return as soon as you have all the necessary information, such as your payment summaries (formerly known as Group Certificates) and relevant receipts.

• October 31, 2025: The standard deadline for individuals to lodge their income tax return. This is the most crucial date for most individuals. If you are lodging through a registered tax agent, you may be granted an extension.

• If Lodging Through a Registered Tax Agent: The deadline for lodging your tax return is typically extended to a later date, often sometime in May the following year (2026). However, you must be registered with a tax agent before October 31, 2025, to qualify for this extension. The specific extension deadline will be confirmed by your tax agent.

• PAYG (Pay As You Go) Instalments: If you are required to pay PAYG instalments (for example, if you receive income from sources other than salary or wages where tax has already been withheld), the payment dates will vary depending on your chosen payment frequency (quarterly or monthly). The ATO will notify you of your specific instalment amounts and due dates. Generally, quarterly instalments are due around the 28th of October, 28th of January, 28th of April, and 28th of July.

• Superannuation Contributions: If you intend to claim a tax deduction for personal superannuation contributions, ensure these are made and received by your superannuation fund by June 30, 2025. You’ll also need to provide your fund with a "Notice of Intent to Claim a Deduction" form and receive an acknowledgement from the fund before lodging your tax return.

Detailed Look at Individual Tax Considerations:

• Payment Summaries (Income Statements): Employers are required to provide employees with income statements outlining their earnings and the amount of tax withheld. These are usually available electronically through myGov. Ensure you have all your income statements before preparing your tax return.

• Deductions: Familiarize yourself with the types of deductions you may be eligible to claim. Common deductions include:

  • Work-Related Expenses: Expenses directly related to your employment, such as uniforms, tools, equipment, self-education, and travel. Keep detailed records and receipts to support your claims. The ATO has specific rules regarding what can and cannot be claimed.
  • Donations: Donations to registered charities.
  • Self-Education Expenses: Expenses related to courses that have a direct connection to your current employment.
  • Investment Property Expenses: Expenses related to managing and maintaining a rental property.
  • Home Office Expenses: If you work from home, you may be able to claim a deduction for running expenses, such as electricity, internet, and phone. The ATO offers different methods for calculating these expenses, including the fixed-rate method and the actual cost method.

• myTax: The ATO’s online platform, myTax, simplifies the tax return lodgement process. It pre-fills much of your information, making it easier to complete your return.

• Tax Offsets: Tax offsets reduce the amount of tax you pay. Common tax offsets include the low and middle income tax offset (LMITO), which has been removed, and the low income tax offset (LITO).

Key Tax Deadlines for Businesses in 2025

Businesses face a more complex tax landscape with various obligations depending on their structure, size, and industry. Staying organized and adhering to deadlines is paramount for business owners.

• Monthly BAS (Business Activity Statement): Businesses registered for GST and with a GST turnover of $20 million or more typically lodge monthly BAS statements. The due date is generally the 21st day of the following month.

• Quarterly BAS (Business Activity Statement): Most small to medium-sized businesses lodge quarterly BAS statements. The due dates are typically:

  • Quarter 1 (July – September): October 28, 2024
  • Quarter 2 (October – December): February 28, 2025
  • Quarter 3 (January – March): April 28, 2025
  • Quarter 4 (April – June): July 28, 2025

  Note: if lodging through a registered BAS Agent, these deadlines may be extended.

• Annual Income Tax Return: The deadline for lodging the annual income tax return depends on the business structure:

  • Companies: The deadline varies depending on the company’s balance date. Generally, if lodging electronically, the deadline is extended.
  • Partnerships and Trusts: Similar to individuals, the deadline is typically October 31, 2025, unless lodging through a registered tax agent, in which case an extension may be granted.

• Superannuation Guarantee Contributions: Employers are required to make superannuation contributions for their employees. These contributions must be paid by the 28th day of the month following the end of each quarter.

  • Quarter 1 (July – September): October 28, 2024
  • Quarter 2 (October – December): January 28, 2025
  • Quarter 3 (January – March): April 28, 2025
  • Quarter 4 (April – June): July 28, 2025

  Failure to pay superannuation guarantee contributions on time can result in significant penalties.

• PAYG Withholding: Businesses are required to withhold PAYG from employee salaries and wages and remit these amounts to the ATO. The frequency of payment depends on the business’s withholding amount.

• Fringe Benefits Tax (FBT): If a business provides fringe benefits to its employees (e.g., company cars, entertainment), it may be liable for FBT. The FBT year runs from April 1st to March 31st. The FBT return is typically due on May 21st, 2025, if lodging electronically, and payment is due on June 25, 2025.

Detailed Look at Business Tax Considerations:

• GST (Goods and Services Tax): Businesses with a GST turnover of $75,000 or more (or $150,000 or more for non-profit organizations) are required to register for GST and collect GST on their sales. GST is remitted to the ATO through the BAS.

• ABN (Australian Business Number): Ensure your ABN details are up-to-date with the Australian Business Register (ABR).

• Record Keeping: Maintain accurate and complete records of all business transactions, including income, expenses, assets, and liabilities. These records are essential for preparing your BAS and income tax return, as well as for potential audits by the ATO.

• Depreciation: Businesses can claim depreciation on certain assets used in their business. Understanding the different depreciation methods (e.g., diminishing value, prime cost) is crucial for maximizing deductions. The instant asset write-off threshold can change, so stay updated on current regulations.

• Small Business Concessions: Small businesses may be eligible for various tax concessions, such as the small business CGT (Capital Gains Tax) concessions and simplified depreciation rules.

• Company Tax Rate: The company tax rate can vary depending on the company’s aggregated turnover and the percentage of passive income. Stay updated on any changes to the company tax rate.

Tax Planning for 2025

Proactive tax planning can help you minimize your tax liability and ensure you meet all your obligations. Consider the following:

• Review Your Business Structure: Ensure your business structure is still the most appropriate for your needs. Factors to consider include asset protection, tax implications, and compliance requirements.

• Maximize Deductions: Identify all eligible deductions and ensure you have the necessary documentation to support your claims.

• Superannuation Planning: Consider making additional superannuation contributions to reduce your taxable income.

• Capital Gains Tax (CGT) Planning: If you are planning to sell an asset, consider the CGT implications and explore strategies to minimize your tax liability.

• Cash Flow Management: Plan your cash flow to ensure you have sufficient funds to meet your tax obligations.
