What Do I Need for My Tax Return? The Complete Australian Checklist to Maximise Your Refund

Tax time is easier, and usually more accurate, when you know what to gather before you start. Whether you are an employee, a sole trader, an investor or a combination of all three, the aim is the same: include all assessable income, claim only deductions you are entitled to, and keep records that support every amount.

A refund is not something to chase by adding up receipts at the last minute. It is the result of a complete and well-prepared return, including the deductions, offsets and tax credits that genuinely apply to your circumstances. This checklist will help you organise the information your accountant or registered tax agent is likely to need.

Start with your personal details and tax-time snapshot

Before looking at income and deductions, make sure the basic information is current. Incorrect personal details or bank details can create unnecessary delays, while missing information can mean your return needs to be amended later.

Have the following ready:

• Your tax file number, if you are preparing information for your tax agent.
• Your current residential address, email address and phone number.
• Your Australian bank account details for any refund.
• Details of your spouse or de facto partner, where relevant to your tax position.
• Details of dependent children, private health insurance and relevant government payments, where applicable.
• Information about any changes during the financial year, such as marriage, separation, a new child, a change in residency status or moving overseas.
• A copy of your prior-year tax return and notice of assessment, particularly if you have carried-forward losses, capital losses, rental property information or business assets.

If you use online services, pre-filled information can be useful, but it should not be treated as a complete tax return. The ATO receives data from employers, banks, health funds, government agencies and other organisations, but some information can arrive later or may not be available for pre-fill at all. Rental income, certain trust distributions and information from newer or overseas platforms are common examples that may require your own records.

For employees, check that each employer income statement is marked “Tax ready” before relying on it. Many employers report payroll information through Single Touch Payroll, so you may not receive the old-style payment summary or “group certificate” you remember from previous years.

Gather records for every type of income

The first part of a good tax return is making sure nothing has been missed. Income does not only mean your salary or wages. If you earned money, received a benefit connected with an income-producing activity, or disposed of an investment asset, it may need to be considered for tax purposes.

Create a folder, digital or paper, with documents for each relevant category.

Employment income

For employees, collect or check:

• Income statements from every employer.
• Details of bonuses, commissions, overtime and back payments.
• Allowances, including travel, car, tool, meal, laundry or working-from-home allowances.
• Employment termination information, if you changed jobs or received a redundancy payment.
• Details of employee share scheme interests, if your employer offered shares or rights.
• Foreign employment income, where relevant.

An allowance is not automatically tax-free simply because it appears separately on a payslip. If it is included in your income statement, it generally needs to be considered in your return. You may be able to claim a deduction for eligible expenses the allowance was intended to cover, but only to the extent you actually incurred those expenses and meet the normal deduction rules.

Side income, freelance work and the sharing economy

Many people now earn income outside their main job. This may come from consulting, freelancing, ride-sourcing, delivery work, online content, selling services through digital platforms, renting out equipment or taking on occasional contract work.

Keep:

• Invoices you issued.
• Platform summaries and payout reports.
• Bank and payment-provider statements.
• Records of cash income.
• Details of any tax withheld from payments.
• Relevant contracts or agreements.
• Expense records connected with earning that income.

Do not assume an activity is too small or informal to matter. The label you give it, such as “hobby”, “side hustle” or “cash job”, does not decide its tax treatment on its own. If you are unsure whether you are carrying on a business or simply earning other income, get advice before lodging.

Investment, property and other income

Investment records are particularly important because they are often spread across multiple providers. Your checklist may include:

• Bank interest statements, including joint accounts.
• Dividend statements and annual tax statements.
• Managed fund, exchange-traded fund and trust distribution statements.
• Foreign income and foreign tax paid records.
• Rental income records and annual managing-agent statements.
• Income from renting out part of your home, a holiday home, a car space or other assets.
• Government payment summaries, where applicable.
• Partnership distribution information.
• Trust distribution statements.
• Any compensation, insurance, grant or settlement payment that may have tax consequences.

Investment income can include interest, dividends, rental income, managed investment trust credits, crypto asset income and capital gains. It may be received directly or through a trust or partnership distribution.

The safest approach is to prepare a list of every bank, broker, property manager, platform, trust, partnership and investment account you used during the year. Then confirm whether you have a statement or report for each one.

Build your deductions checklist, then test each claim

A tax deduction is not simply an expense that feels connected to work. For a work-related deduction, the core questions are straightforward:

• Did you pay for it yourself?
• Were you not reimbursed by your employer or another person?
• Is there a direct connection between the expense and earning your income?
• Do you have appropriate records?
• If it had both private and work use, have you claimed only the work-related portion?

Expenses that are private, domestic or capital in nature are generally not immediately deductible. Everyday travel between home and a regular workplace, ordinary clothing and personal meals are common areas where people make incorrect assumptions.

Your deduction checklist may include the following, depending on your job and circumstances:

• Union and professional association fees.
• Work-related licences, registrations and subscriptions.
• Protective clothing, uniforms or occupation-specific clothing, plus eligible cleaning costs.
• Tools, equipment, computers, software and reference materials.
• Mobile phone, internet and home phone expenses, apportioned for work use.
• Work-related travel and accommodation.
• Vehicle expenses where travel is genuinely work-related and the required records are kept.
• Work-related education, training, seminars and conferences.
• Working-from-home running expenses.
• Gifts or donations to eligible recipients.
• The cost of managing your tax affairs, including a tax agent’s fee for preparing the previous year’s return.
• Income-producing investment expenses, such as certain account fees, investment advice costs and interest expenses, where eligible.

Self-education costs need a sufficient connection with your current employment activities. The course should maintain or improve skills or knowledge used in your current work, or be likely to increase income from those activities. A course undertaken to move into an entirely different occupation may not satisfy this connection.

Records matter as much as the expense

Keep receipts, invoices, diary notes, logbooks, statements and calculations showing how you worked out the work-related portion of mixed expenses. A bank or credit card statement can help show that a payment occurred, but it is not always enough on its own to prove what was purchased and why it was deductible.

For most work-related expense claims above the relevant substantiation exception, you need written evidence for the full claim, not only the portion above the exception. Special record-keeping rules can apply to car, travel and allowance-related claims, so do not rely on a rough estimate.

For working-from-home claims, you need to be working from home to fulfil your employment duties, incur additional running expenses and maintain records appropriate to the calculation method you use. Simply checking emails at home occasionally will not necessarily support a claim.

Take extra care with property, shares, crypto and capital gains

Investments can make a return more complex because the tax outcome is not always limited to the cash you received. A sale, transfer, exchange or other disposal may create a capital gains tax event, even if the money was reinvested.

Rental property records

If you own a rental property, gather:

• Annual property manager statements.
• Rental income records and tenant lease information.
• Loan statements and interest records.
• Council rates, water charges, insurance and body corporate records.
• Repairs and maintenance invoices.
• Invoices for new appliances, equipment and improvements.
• Capital works information, where available.
• Purchase and sale contracts, settlement statements and legal costs.
• Records of periods when the property was rented, genuinely available for rent, used privately or vacant.

Rental income can include amounts received by you or your managing agent, as well as certain associated payments. Expenses may need to be apportioned if a property was only partly rented, used privately, or not genuinely available for rent. Some costs may be deductible immediately, while others are capital in nature and may need different treatment over time or when calculating a capital gain or loss on sale.

Shares, managed funds and crypto assets

For shares and managed funds, retain dividend statements, annual tax statements, contract notes, distribution statements and records of brokerage or other acquisition and disposal costs.

For crypto assets, keep a complete transaction history rather than relying on a closing balance alone. Records should include purchases, sales, swaps, transfers between wallets or platforms, staking or other rewards, Australian dollar values at the time of transactions, transaction dates, wallet records and associated costs. Swapping one crypto asset for another can be a disposal for capital gains tax purposes, not merely an internal transfer.

A common mistake is to report only a cash withdrawal from an exchange. The tax position can be affected earlier, for example when an asset is exchanged for another asset, used to buy goods or services, gifted or otherwise disposed of.

Sole traders and small business owners need a separate business pack

If you are a sole trader, your business income and expenses form part of your individual tax return. That does not mean the process should be informal. A clean set of business records makes it easier to prepare the return, reconcile BAS reporting and identify deductible expenses without mixing them up with personal spending.

Your business tax pack should include:

• Your ABN and business details.
• A profit and loss report for the full financial year.
• Balance sheet or asset records, where relevant.
• Sales invoices, quotes, contracts and payment reports.
• Business bank account and credit card statements.
• Merchant terminal, payment platform and online marketplace reports.
• Supplier invoices and receipts.
• Motor vehicle records, including the basis for any business-use percentage.
• Asset purchases and an up-to-date depreciation or asset register.
• Loan documents, interest statements and finance agreements.
• Inventory records, where applicable.
• BAS, PAYG instalment and GST reconciliation reports.
• Payroll reports, wage records and employee entitlement information.
• Superannuation payment records for employees.
• Records of amounts paid to contractors.
• Details of business grants, rebates or government support payments.
• Details of bad debts, stock write-offs, insurance proceeds or unusual transactions.

A GST-registered business should also reconcile the GST figures in its accounting records with the amounts reported through BAS. Good bookkeeping throughout the year is far more reliable than trying to reconstruct transactions from memory after EOFY.

If you operate through a company, trust, partnership or self-managed super fund, do not assume your individual return is the only return required. These structures can have separate reporting and tax obligations. Your personal return may include amounts such as wages, dividends, director-related payments, trust distributions or partnership income, but the entity’s records still need to be prepared correctly.

A practical way to prepare your information

A simple system can prevent the last-minute rush. Create folders for income, deductions, investments, property, business, superannuation and prior-year documents. Save digital copies as you receive them, rather than waiting until tax time.

Consider the example of a professional who has a full-time job, works from home several days a week, earns occasional consulting income and owns a rental property with a partner. Their tax return may require an employment income statement, a work-from-home record, consulting invoices and expenses, property manager reports, loan interest statements, repair invoices and ownership details. If they only provide their salary information, the return may be incomplete. If they claim every household expense or property cost without checking the rules, the return may be inaccurate.

Before lodging, complete one final review:

• Have you included every income source?
• Have you checked pre-filled data against your own records?
• Have you separated private and work or business expenses?
• Have you removed reimbursed expenses?
• Do you have evidence for each deduction?
• Have you considered investment disposals, not just income received?
• Have you retained records in an organised, accessible format?

In most cases, records supporting a tax return should be retained for five years from the date the return is lodged. Some records, particularly those connected with capital gains tax assets, carried-forward losses or longer-term property ownership, may need to be retained for longer.

Make the checklist work for your circumstances

The best tax return is not the one with the longest list of deductions. It is the one that accurately reflects your income, expenses, investments and business activities, with records to support each position taken.

A little preparation can make a meaningful difference to the quality of your return and help reduce the risk of missed income, missed deductions or avoidable amendments.
