Tax season arrives every year without fail, yet it still catches plenty of Australians off guard. Whether you are a salaried employee with a straightforward return or a small business owner juggling multiple income streams, knowing how to prepare taxes properly can save you money, reduce stress, and keep you on the right side of the Australian Taxation Office (ATO). This guide walks you through the entire process, from gathering your records months in advance to lodging your return with confidence.
The Australian financial year runs from 1 July to 30 June. Everything you earn and every deduction you claim during that period gets reported in your annual tax return. For individuals who lodge their own return, the standard deadline is 31 October. If you use a registered tax agent and are on their lodgement program before that date, you may be eligible for an extension, often through to 15 May the following year.
Understanding these basics is the first step. The rest of this guide covers everything you need to turn tax time from a dreaded chore into a manageable, even rewarding, part of your financial calendar.
Getting Your Tax Preparation Started: What to Gather Before You Begin
The single biggest factor in a smooth tax return is organisation. The people who dread tax time the most are usually the ones scrambling for receipts, bank statements, and payment summaries at the last minute. Start early, and the whole experience changes.
Here is what you need to pull together before you sit down to lodge.
Income Records You Must Have Ready
The ATO receives data from employers, banks, government agencies, cryptocurrency exchanges, and share registries throughout the year. When you log into myTax through your myGov account, much of this information will be pre-filled. However, you should not rely on pre-fill data alone. Always cross-check against your own records.
Your income statement from your employer, previously known as a payment summary, is the cornerstone document. Most employers finalise these through Single Touch Payroll (STP) by 14 July each year, making them accessible via your myGov account. If you have multiple employers, make sure you have statements from each one.
Beyond employment income, you need records for bank interest, share dividends, distributions from managed funds, rental income from investment properties, any government payments you received during the year, capital gains from the sale of assets including property and cryptocurrency, and income from freelance work, side hustles, or the gig economy.
Every dollar of income must be declared, regardless of whether tax has already been withheld from it. The ATO’s data-matching systems are sophisticated and cross-reference information from thousands of sources. Under-reporting income is one of the most common audit triggers, and it is entirely avoidable with good record-keeping.
Expense Records and Receipts for Deductions
Deductions reduce your taxable income, which in turn reduces the amount of tax you owe. But the ATO has three firm rules about claiming deductions: you must have spent the money yourself and not been reimbursed, the expense must be directly related to earning your income, and you must have a record to prove it.
Common deductible expenses for employees include work-related travel between job sites (though not your regular commute from home to your usual workplace), uniforms and protective clothing required for work, tools and equipment, union and professional association fees, self-education expenses that are directly connected to your current employment, and the work-related portion of your mobile phone and internet bills.
If you work from home, the ATO currently allows the fixed rate method at 67 cents per hour. You must keep a record of the actual hours you worked from home across the entire financial year. Estimates are not accepted.
For small business owners and sole traders, the deduction landscape is broader and includes business premises costs, vehicle expenses, marketing and advertising, professional development, accounting fees, and business insurance premiums. The key is maintaining detailed records throughout the year rather than trying to reconstruct them at tax time.
Keep your receipts for at least five years after lodging your return. Digital copies are perfectly acceptable, and there are numerous apps and cloud storage solutions that make this easy.
Understanding the Australian Tax System: Rates, Thresholds, and Offsets
To make informed decisions about your tax preparation, it helps to understand the structure you are working within. Australia’s income tax system is progressive, meaning the more you earn, the higher the rate applied to each additional dollar of income.
Current Tax Rates and the Tax-Free Threshold
The tax-free threshold in Australia is $18,200. This means the first $18,200 you earn in a financial year is not subject to income tax. Above that amount, progressive rates apply in bands. The rates increase as your taxable income rises, with the highest marginal rate applying to income above the top threshold.
On top of your income tax, most taxpayers pay the Medicare levy, which is currently 2% of taxable income. Some higher-income earners who do not hold an appropriate level of private hospital cover may also pay the Medicare levy surcharge, which ranges from 1% to 1.5% depending on income and family status.
Understanding where you sit within these tax brackets helps you estimate your likely tax bill or refund and plan accordingly. If you are close to a bracket boundary, strategies like timing deductible expenses or making additional superannuation contributions before 30 June can make a meaningful difference.
Tax Offsets That Could Reduce What You Owe
Tax offsets, sometimes called rebates, directly reduce the amount of tax you pay. They differ from deductions, which reduce your taxable income. The Low Income Tax Offset (LITO) provides up to $700 for eligible taxpayers on lower incomes. This offset is calculated automatically by the ATO when you lodge your return.
Other offsets may be available depending on your circumstances, including the seniors and pensioners tax offset, the private health insurance rebate, and offsets for remote area residents. If you are eligible for any of these, they will typically be factored in during the assessment process, but it pays to be aware of them so you can check your Notice of Assessment once it arrives.
Choosing How to Lodge: DIY vs Professional Tax Help
One of the most important decisions you will make each tax season is whether to lodge your return yourself or engage a registered tax agent. Both approaches have their place, and the right choice depends on the complexity of your financial situation.
Lodging Your Own Return Through myTax
The ATO’s myTax platform is a free online tool accessible through your myGov account. It is designed for individuals with relatively straightforward tax affairs: a single employer, some bank interest, maybe a handful of work-related deductions. The system pre-fills much of your information and guides you through the process step by step.
If your return is simple, myTax is a perfectly good option. It costs nothing, and you can lodge from 1 July onwards. However, there is a case for waiting until late July before you lodge, because by then most employers, banks, and health funds will have submitted their data to the ATO, making pre-fill information more complete and accurate. Lodging too early with incomplete data can lead to errors that require amendments later, creating unnecessary administration.
The main risk with self-lodging is missing deductions you are entitled to or claiming things incorrectly. The ATO’s data-matching capabilities are extensive, and errors, whether intentional or accidental, are increasingly easy for them to detect.
Working with a Registered Tax Agent
A registered tax agent brings expertise that can save you money and stress, particularly if your tax affairs involve investment properties, share portfolios, capital gains, business income, complex work-related deductions, or foreign income. Agents understand the nuances of the tax law and can identify deductions and strategies you might overlook.
Beyond the expertise, using a tax agent gives you access to extended lodgement deadlines. If you are registered with an agent before 31 October, your return may not be due until May the following year. This can be a significant advantage if your financial year-end is complicated or if you simply need more time to get your records in order.
The cost of a tax agent is itself tax deductible in the following financial year. For many Australians, the fee is more than offset by the additional deductions a professional identifies.

Tax Preparation for Small Business Owners and Sole Traders
Small business owners face a more complex tax preparation process than employees. If you operate as a sole trader, your business income and expenses are reported in your individual tax return. Companies, partnerships, and trusts each have their own lodgement requirements and deadlines.
Record-Keeping Throughout the Year
The ATO expects small businesses to maintain accurate records of all transactions. This includes income from sales and services, operating expenses, asset purchases and depreciation schedules, motor vehicle logbooks if claiming business use of a vehicle, stock and inventory records, and superannuation contributions for employees.
Good bookkeeping software can automate much of this, categorising transactions as they flow through your business bank account and generating reports that make tax time significantly easier. If you are still tracking expenses manually or relying on shoeboxes of receipts, investing in a proper bookkeeping system will pay for itself many times over.
BAS and GST Obligations
If your business turns over more than $75,000 per year, you must register for the Goods and Services Tax (GST) and lodge Business Activity Statements (BAS). BAS can be lodged monthly, quarterly, or annually depending on your turnover and circumstances.
Staying on top of BAS throughout the year means your end-of-year tax preparation is far less burdensome. If your BAS lodgements are up to date and accurate, much of the heavy lifting for your annual return has already been done.
Instant Asset Write-Off and Depreciation
The Australian government has periodically offered accelerated depreciation measures for small businesses, including instant asset write-offs for eligible purchases. These provisions can significantly reduce your taxable income in the year you acquire a business asset, whether that is a vehicle, equipment, technology, or fit-out. Check the current thresholds with the ATO or your tax agent before making large purchases, as the rules and limits have changed several times in recent years.
Common Mistakes to Avoid When Preparing Your Tax Return
Even well-intentioned taxpayers make errors that can trigger ATO scrutiny or result in penalties. Here are some of the most frequent pitfalls.
Forgetting to declare all income is the most common issue. Bank interest, dividends from shares, income from a side hustle, and even some government payments are taxable. If it appeared in your bank account as income, chances are the ATO already knows about it.
Claiming deductions without adequate records is another frequent problem. A receipt, invoice, or logbook is required for every deduction you claim. The ATO has made it clear that estimates and round numbers are red flags.
Incorrectly apportioning expenses is an area the ATO specifically targets each year. If you use your phone for both personal and work purposes, you can only claim the work-related percentage. The same applies to internet, home office expenses, and vehicle use. Be honest and methodical with your apportioning.
Lodging too early before pre-fill data is available can result in incomplete or inaccurate returns. Waiting until late July or early August gives the ATO time to populate your information from employers, banks, and government agencies.
Not reviewing your Notice of Assessment after you lodge is a missed opportunity. The Notice of Assessment confirms the ATO’s calculation of your tax liability or refund. If something looks wrong, you have the right to request a review or lodge an amendment.
Planning Ahead: Year-Round Tax Strategies That Pay Off
The best tax outcomes do not happen at lodgement time. They happen throughout the year through consistent planning and smart financial decisions.
Superannuation Contributions
Making additional personal contributions to your superannuation fund before 30 June can reduce your taxable income, since concessional (before-tax) contributions are taxed at just 15% within the super fund rather than at your marginal tax rate. There are annual caps on concessional contributions, so check the current limits before making additional payments.
Timing Your Expenses
If you know you have a deductible expense coming up, consider whether it makes more sense to incur it before or after 30 June. Bringing a deductible expense into the current financial year can reduce your tax bill now, while deferring it can reduce it next year. The right timing depends on your income expectations for each year.
Keeping Digital Records
The ATO accepts digital records, and using a dedicated app or cloud storage system to photograph and store receipts as you go eliminates the end-of-year scramble. Many accounting apps integrate directly with bank feeds, making categorisation almost automatic.
Reviewing Your PAYG Withholding
If you consistently receive large refunds, it may mean too much tax is being withheld from your pay throughout the year. You can apply to the ATO for a variation to your PAYG withholding rate, which puts more money in your pocket each pay cycle rather than lending it interest-free to the government until your refund arrives.
What Happens After You Lodge
Once your return is submitted, the ATO processes it and issues a Notice of Assessment. For straightforward returns lodged through myTax, this can happen within two weeks. More complex returns or those selected for review may take longer.
If you are entitled to a refund, it will be paid directly into the bank account you nominated during lodgement. If you have a tax debt, the Notice of Assessment will outline the amount owing and the due date for payment. If you cannot pay the full amount by the due date, contact the ATO early to discuss a payment plan. They are generally more accommodating when you reach out proactively rather than waiting for them to chase you.
Keep a copy of your lodged return and the Notice of Assessment with your records. If the ATO ever queries your return, having these documents readily available makes the process much smoother.
Penalties for Late Lodgement and How to Avoid Them
The ATO takes lodgement deadlines seriously. If you miss the 31 October deadline for self-lodgers, failure-to-lodge penalties can apply. These start at $330 for each 28-day period your return is overdue, up to a maximum of $1,650. These penalties apply even if you do not owe any tax.
If you owe tax and pay late, the ATO also charges the General Interest Charge (GIC) on the outstanding amount. The GIC rate is updated quarterly and compounds daily, so even small debts can grow quickly if left unresolved.
The simplest way to avoid penalties is to lodge on time. If you cannot meet the deadline, engaging a registered tax agent before 31 October gives you an automatic extension. Alternatively, if you have a genuine reason for being late, contact the ATO before the deadline to discuss your options.
Frequently Asked Questions
When is the deadline to lodge my Australian tax return?
For individuals who lodge their own return, the standard deadline is 31 October following the end of the financial year. If you engage a registered tax agent and are on their client list before 31 October, you may qualify for an extended deadline, often through to 15 May the following year. Specific deadlines for companies, trusts, and self-managed super funds vary based on their circumstances and lodgement history.
What records do I need to keep for my tax return?
You should keep records of all income received during the financial year, including income statements from employers, bank interest statements, dividend statements, rental income records, and records of any other income sources. For deductions, you need receipts, invoices, or logbooks that support every claim. The ATO requires you to keep these records for at least five years after lodging your return.
Can I claim working from home expenses on my tax return?
Yes, if you work from home as part of your employment, you can claim a deduction using the ATO’s fixed rate method, currently set at 67 cents per hour. You must keep a record of the actual hours you worked from home across the entire financial year. Estimates are not accepted. The deduction covers running expenses such as electricity, phone, internet, and depreciation of office furniture and equipment.
What happens if I make a mistake on my tax return?
If you discover an error after lodging, you can request an amendment through myTax or your tax agent. The ATO allows amendments for most returns within two years for individuals (or four years in some circumstances). If the ATO identifies the error first, they may adjust your assessment and potentially apply penalties depending on the nature and severity of the mistake. Honest mistakes are generally treated more leniently than deliberate under-reporting.
Should I use a tax agent or lodge my own return?
If your tax affairs are straightforward, with a single employer, minimal investments, and simple deductions, the ATO’s free myTax platform is a perfectly suitable option. However, if you have investment properties, share portfolios, capital gains, business income, or complex deduction claims, a registered tax agent can help you maximise your return, avoid errors, and provide peace of mind. The agent’s fee is tax deductible in the following year, and many people find the additional deductions identified more than cover the cost.
