EOFY Tax Checklist: What to Prepare Before Lodging Your Tax Return
- 1 day ago
- 10 min read
The end of the financial year signals a critical period for Australian taxpayers to organise their financial records and prepare for tax return lodgement. A methodical approach ensures compliance, substantiates claims, and provides a clear financial overview. This guide serves as a comprehensive EOFY tax checklist, detailing what to prepare before lodging your tax return for the FY 2025–26. By systematically gathering the necessary documentation, individuals and businesses can navigate the tax process with greater confidence and accuracy, ensuring all obligations are met and entitlements are correctly claimed.
Based on client interactions, Baron Tax & Accounting has observed that many taxpayers in Brisbane underestimate the importance of organising digital receipts and bank statements throughout the year, leading to a frantic search for records close to the lodgement deadline. A proactive, structured approach to documentation can significantly reduce stress and improve the accuracy of a tax return.
1. Income Records
The foundational step in any EOFY tax checklist is the meticulous compilation of all income-related documentation. This process involves gathering evidence of every dollar earned, which forms the basis of your assessable income. Accurate income reporting is not just a best practice; it is a legal requirement, and failing to declare all income can lead to Australian Taxation Office (ATO) inquiries and penalties.
Through Single Touch Payroll (STP), the ATO receives real-time salary, wage, and superannuation data from employers. This means your income information is often pre-filled in your myGov account. However, it is crucial to manually verify these figures against your own records, as pre-fill data can sometimes be incomplete or delayed.
Actionable Steps for Gathering Income Records
For Employees: Most employers no longer issue payment summaries. Instead, your income statement will be marked as 'Tax ready' in your myGov account, typically by 14 July. Download this statement and cross-reference it with your final payslip.
For Sole Traders: Systematically collate all invoices issued to clients. A simple spreadsheet listing each invoice number, date, client, and amount can prevent errors. This is a vital practice for business owners across Brisbane, from tradespeople in Rocklea to consultants in the CBD.
For Diverse Income Streams: Actively gather statements for all other sources. This includes interest earned from bank accounts, dividend statements from shares, distribution statements from managed funds, and payment summaries from superannuation or pension funds.
2. Work-Related and Business Expense Records
A critical component of any EOFY tax checklist is the comprehensive documentation of all legitimate business and work-related expenses. These records are the evidence required to substantiate your deduction claims, which are fundamental to reducing your assessable income. Maintaining accurate and organised expense records is a non-negotiable aspect of ATO compliance and directly impacts your final tax position.

For businesses and sole traders, from a freelance graphic designer in New Farm to a construction firm in Archerfield, these deductions represent the costs of earning income. Without proper proof, legitimate expenses may be disallowed during an ATO review. To ensure you claim all eligible deductions, it's essential to understand how to properly track business expenses the right way throughout the year. Knowing what small business tax deductions you can claim is the first step; proving them is the next.
Actionable Steps for Gathering Expense Records
Implement a System: Use accounting software or dedicated expense-tracking apps to capture receipts and invoices in real-time. This avoids the end-of-year scramble to find faded paper receipts.
Digitise Everything: Take clear digital photos or scans of all receipts and store them securely in the cloud. Digital copies are a reliable backup against lost or damaged originals.
Maintain a Vehicle Logbook: If you use a vehicle for business or work purposes, a 12-week continuous logbook is a common method used to determine the business-use percentage. Record odometer readings, journey dates, purpose, and kilometres travelled.
Document Apportionment: For expenses with both business and private use, such as a mobile phone or home internet, document your calculation method for apportioning the business-related portion. This demonstrates a reasonable basis for your claim.
3. Capital Gains Tax (CGT) Records
Properly documenting asset transactions is a critical part of any EOFY tax checklist, particularly for those who have sold assets like property or shares. Every sale or disposal of a capital asset triggers a Capital Gains Tax (CGT) event, which must be reported in your tax return. The ATO requires detailed records to substantiate the calculation of any capital gain or loss.

A capital gain arises when you sell an asset for more than its cost base, which includes the original purchase price plus certain incidental costs. A capital loss occurs if the sale price is less than the cost base. Accurate record-keeping is the only way to correctly calculate this outcome and claim any eligible concessions, such as the 50% CGT discount for assets held over 12 months. You can explore a detailed breakdown of how CGT on investment property is calculated in Australia to understand the nuances.
Actionable Steps for Gathering CGT Records
For Property: Collate all documents related to the purchase and sale, including settlement statements and agent commission invoices. Keep receipts for all capital improvements, such as major renovations, as these may form part of the cost base.
For Shares and Crypto: Compile transaction confirmations from your broker or exchange for every purchase and sale. These statements must show the date, price, and quantity of each transaction.
For Main Residence Changes: If you ever used your main residence to produce income (e.g., by renting it out), you must document the dates it was used for this purpose and obtain a market valuation at the time it first started generating income.
4. Investment Income Statements
A crucial part of a thorough EOFY tax checklist involves the diligent collation of all statements related to investment income. This includes earnings from bank accounts, dividends from shares, and distributions from managed funds or trusts. Precisely reporting this income is a non-negotiable compliance obligation, as the ATO cross-references data from financial institutions.

While the ATO's pre-fill service often populates some of this data directly into your tax return, it should not be relied upon exclusively. The information can be incomplete. Verifying these amounts against your own documentation is essential to ensure your tax return is correct.
Actionable Steps for Gathering Investment Records
Bank Interest: Download or request an annual interest statement from every bank where you hold an account.
Share Dividends: Collect all dividend statements issued during the financial year. Pay close attention to franking credits, as these can reduce your tax liability.
Managed Funds and Trusts: Gather the annual tax statements, often sent out between July and September. These detail the various components of the distribution. A retiree in Brisbane with a diverse portfolio would need to consolidate these from multiple fund managers.
Foreign Investments: Meticulously document all income from overseas sources. Keep a record of the exchange rates used to convert the income into Australian dollars.
5. Work-Related Asset and Depreciation Records
A key component of any EOFY tax checklist is the thorough documentation of work-related assets. This involves collating records for any equipment, tools, or other items purchased to help you earn your income. These records are essential for claiming deductions, particularly through depreciation, which allows you to claim a portion of the asset's cost over its effective life.
For items costing over $300, you generally cannot claim the full purchase price in one year. Instead, the cost must be spread out (depreciated) over the asset's useful life as determined by the ATO's guidelines. For less expensive items, an immediate deduction may be available. Accurate record-keeping is the only way to correctly calculate and substantiate these claims if the ATO asks for proof.
Actionable Steps for Gathering Depreciation Records
Create an Asset Register: For depreciable assets, maintain a register listing each item, its cost, purchase date, and work-use percentage. This is your primary evidence for claiming depreciation.
Document Low-Cost Items: For items costing less than $300, you can generally claim an immediate deduction, provided you have a receipt and the item is predominantly for work use.
Apportion Private Use: If an asset is used for both work and private purposes (e.g., a laptop), you must keep a record of your work-use percentage to correctly apportion the deduction.
6. Rental Property Documentation
For property investors, a meticulous approach to documentation is fundamental. Collating all income and expenditure related to your rental property is a critical part of preparing your EOFY tax checklist. These records substantiate claims for deductions, calculate your net rental profit or loss, and are essential for managing CGT obligations.
The ATO closely scrutinises rental property claims, making complete and organised documentation non-negotiable for compliance. A well-documented file is especially important when exploring the mechanics of negative gearing, where deductible expenses exceed rental income.
Actionable Steps for Gathering Rental Property Records
Financial Segregation: Maintain a separate bank account exclusively for rental income and expenses. This simplifies tracking and provides a clear financial record. It is a common practice for landlords across Brisbane.
Document Repairs vs. Improvements: Keep detailed records and invoices for all work done on the property. Clearly differentiate between repairs (e.g., fixing a broken window), which are generally deductible immediately, and improvements (e.g., a kitchen renovation), which are treated as capital works and depreciated over years.
Obtain a Depreciation Schedule: Engage a qualified quantity surveyor to prepare a capital works and depreciation schedule. This report identifies the value of depreciable assets and building components, allowing you to claim deductions for wear and tear.
Track All Expenses: Systematically file receipts and statements for all costs, including mortgage interest, council rates, water charges, land tax, insurance, property management fees, and advertising for tenants.
7. Superannuation Contribution Records
A critical part of any thorough EOFY tax checklist involves collating all documents related to superannuation. This includes records of employer contributions, personal contributions for which you intend to claim a tax deduction, and any salary sacrifice arrangements. Proper documentation is essential for potentially reducing your taxable income and for ensuring you comply with the annual contribution caps set by the ATO.
Strategic superannuation contributions are a tool for wealth creation and tax management. For those wanting to understand specific strategies better, it's worth learning about unlocking your salary sacrifice benefits with proper guidance.
Actionable Steps for Gathering Superannuation Records
For Personal Contributions: If you made personal super contributions and intend to claim a deduction, you must provide a 'Notice of intent to claim or vary a deduction for personal super contributions' to your fund and receive an acknowledgement from them before you lodge your return. Keep copies of both documents.
For All Contributions: Download your annual superannuation fund statement, which details all contributions received. Scrutinise this statement to ensure it correctly reflects all employer, salary sacrificed, and personal contributions made throughout the year.
8. Charitable Donation Records
A crucial component of any EOFY tax checklist is the careful collection of records for all charitable donations. To claim a tax deduction for your generosity, you must be able to substantiate the donation with proper documentation. The ATO requires that donations of $2 or more be made to a Deductible Gift Recipient (DGR) to be eligible for a tax deduction.
Actionable Steps for Gathering Donation Records
Verify DGR Status: Before donating, confirm the charity is a registered DGR by checking the Australian Business Register's ABN Lookup tool.
Obtain Official Receipts: For every donation of $2 or more, ensure you receive an official receipt from the charity. This receipt must show the charity's name and ABN, state that it is a donation, and specify the date and amount.
Keep Digital Copies: As soon as you receive a physical or email receipt, save a digital copy in a dedicated folder for the financial year.
9. Records for All Other Deductions
Beyond the main categories, a final review is needed to ensure all other potential deductions are accounted for. This involves gathering clear evidence for every other work-related or personal expense you intend to claim. Having your documentation in order demonstrates compliance and validates your claims. As you gather your records, having a robust strategy for organising deductible expenses can significantly reduce stress and improve accuracy.

Actionable Steps for Gathering Other Expense Records
Professional Memberships & Subscriptions: Collate renewal notices and invoices for union fees, professional association memberships, and subscriptions to work-related journals or publications.
Income Protection Insurance: If you paid for income protection insurance premiums from your personal bank account (i.e., not through super), the premiums are generally deductible. Obtain your annual policy statement.
Tax Agent Fees: The fee you paid last year to prepare your tax return is deductible in this year's return. Locate the invoice from your tax agent.
Claims Without Receipts: For small expense claims, the ATO has specific rules. Investigate the guidelines on what you can claim without receipts in Australia to understand the limits and requirements.

This EOFY tax checklist provides a structured framework for preparing to lodge your tax return. Key compliance requirements include declaring all assessable income, substantiating all deduction claims with valid evidence, and correctly calculating obligations for complex areas like Capital Gains Tax and superannuation contributions.
Record Category | Key Documentation | Primary Risk Area | Brisbane-Relevant Consideration |
|---|---|---|---|
Income | Income Statements, Invoices, Bank & Dividend Statements | Under-reporting income, especially from side-hustles or investments. | Managing income from diverse sources common in Brisbane's gig economy. |
Deductions | Receipts, Invoices, Logbooks, Diaries | Claiming expenses without adequate proof or incorrect apportionment. | Substantiating vehicle claims for travel between job sites across the city. |
CGT | Purchase/Sale Contracts, Valuation Reports | Incorrect calculation of the cost base or misapplication of exemptions. | Correctly calculating CGT on investment properties in high-growth suburbs. |
Superannuation | Notice of Intent to Claim, Fund Statements | Exceeding contribution caps or lodging before receiving fund acknowledgement. | Self-employed individuals ensuring timely contributions and notices. |
Rental Property | Depreciation Schedules, Expense Invoices | Misclassifying capital improvements as immediately deductible repairs. | Obtaining depreciation schedules for new and established rental properties. |
The key deadline for self-lodgers is 31 October. If you use a registered tax agent, lodgement deadlines are typically extended, but you must engage them before 31 October. A primary risk area is relying solely on ATO pre-fill data, which may be incomplete or incorrect. For residents and business owners in Brisbane, specific considerations include substantiating travel between dispersed work sites and correctly managing records for investment properties in a dynamic market.
