The 2026 Year-End Tax Checklist for Australian Individuals

30 June is coming. The end of the 2025–26 financial year is the most important date on the Australian tax calendar — and it is the one most people treat as a vague deadline rather than a hard stop.

It is a hard stop. Expenses paid after 30 June belong to next year’s return. Records not kept by 30 June are gone. Super contributions not made by 30 June do not count. The ATO does not grant personal extensions because you forgot.

This checklist is structured around three lanes: PAYG employees, sole traders and ABN holders, and people who have both. Same week-by-week skeleton, adapted to your situation. Work through your lane, tick things off, and walk into July with nothing on the floor.

Why Year-End Tax Preparation Matters

The Australian tax year runs 1 July to 30 June. That boundary creates real, time-sensitive consequences:

• Income and expenses either fall inside the year or they do not — there is no rounding.
• Deductions for depreciating assets (equipment, tools, computers) can only be claimed from the date of purchase. Buy before 30 June and the asset depreciates from this year. Buy after and you wait twelve months.
• Personal contributions to superannuation qualify for a deduction only if the super fund receives the money AND you lodge a valid Notice of Intent to Claim Deduction before you lodge your return — both conditions must be met.
• Donations to DGR-registered charities are deductible only in the year the payment is made. A donation on 1 July next year is next year’s problem.
• Working-from-home deduction methods require records that end on 30 June. Gaps in your log can reduce your claim.

The ATO’s records guidance is clear: you need written evidence for most claims, kept for five years from the date you lodge. The week-by-week checklist below is about making sure the evidence exists before the clock runs out.

ATO reference: Records you need to keep

The PAYG Employee Year-End Checklist

You earn a salary or wages. Your employer handles PAYG withholding. Your return is often simpler than a sole trader’s, but “simpler” does not mean “empty.” Most PAYG employees leave money on the table because they do not gather their deduction evidence before 30 June.

Work through the four weeks below. The exact calendar dates shift each year but the tasks are fixed.

Week 1 (early June): Gather income documents

• Check your income from all sources: salary, wages, second job, dividends, interest from savings accounts, Centrelink payments (some are taxable). These will largely be pre-filled by the ATO after 30 June, but you need to know what is coming.
• If you received any employment termination payments, redundancy payments, or back-pay during the year, flag them — they have specific tax treatment.
• If you have a HECS-HELP or other study loan, note your repayment threshold. The ATO calculates compulsory repayments automatically, but knowing your approximate income helps you plan.

Week 2 (mid-June): Finalise work-related deduction records

• Working from home: Confirm your method (actual cost method or the fixed rate method — check the current ATO rate per hour before you rely on any figure). Ensure your work-hours log is current to 30 June. Gaps after this date cannot be backdated.
• Vehicle: If you use the logbook method, is your logbook current and does it cover at least twelve weeks from a representative period? If you use cents per kilometre, total your work-related kilometres for the year now — the ATO rate changes annually, so check the current figure.
• Tools, equipment and work clothing: Gather all receipts. Items $300 or under and used primarily for work can be claimed in full. Over $300 may need to be depreciated. Keep the receipts regardless.
• Union fees and professional memberships: Pull receipts or bank statements showing payments.
• Self-education expenses: If you completed study directly related to your current job, gather enrolment receipts, textbook costs and travel.
• Income protection insurance: If you pay premiums for a policy that replaces income (not a lump-sum trauma policy), those premiums are generally deductible. Check your statement.

Week 3 (third week of June): Donations and super

• Donations: Check your records for any donations made to DGR-registered charities this year. Receipts are required for individual donations of $2 or more. End-of-financial-year appeals typically flood in during June — if you intend to donate, do it before 30 June.
• Personal super contributions: If you intend to claim a deduction for personal super contributions (i.e., contributions made from your own after-tax money, not via salary sacrifice), the money must reach the fund before 30 June. You then need to lodge a Notice of Intent to Claim Deduction with your super fund — get this done before you lodge your return.

Week 4 (final days of June): Equipment cut-off and finalise

• If you need a laptop, desk, phone, tools, or any work equipment and you were going to buy it anyway, buy it before 30 June. The ATO depreciates assets from the date of purchase — a $2,000 laptop bought on 29 June gives you this year’s depreciation claim. The same laptop bought on 1 July starts next year.
• Review your bank statements for any work-related payments you might have forgotten — subscriptions, software, professional development.
• Download or print your final payslip and any salary sacrifice summaries. Cross-check them when your employer’s PAYG summary uploads to myGov after 30 June.

Ready to lodge? For straightforward PAYG employees with simple deductions, the Quick Tax Return ($35) is the right product. If you have material deductions — working from home, vehicle, equipment, investment income — step up to the Full Tax Return ($65). Both include registered tax agent review before the ATO receives anything.

The Sole Trader and ABN Holder Year-End Checklist

If you operate under an ABN — as a sole trader, contractor, freelancer, consultant, rideshare driver, or small business operator — the stakes at year-end are higher. The numbers are bigger, the obligations are more complex, and the ATO’s expectations of your record-keeping are stricter.

30 June is also the end of your BAS quarter if you are on a quarterly lodgement cycle. That creates two deadlines converging at once.

Week 1 (early June): Income reconciliation and BAS prep

• Reconcile all income: invoices issued, amounts received, any outstanding debtors you want to include. Cash-basis taxpayers include amounts received; accruals-basis taxpayers include amounts earned regardless of payment.
• If you are registered for GST: reconcile your GST collected and GST paid for the quarter. Your Q4 BAS (April–June) is due 28 July, but the data collection should start now.
• Check for any government grants or COVID-related payments received during the year — these are generally assessable income.

Week 2 (mid-June): Deductions and asset register

• Review every business expense category: materials, subcontractors, software, subscriptions, marketing, insurance, accounting fees, bank charges, vehicle, telephone and internet (business-use percentage), home office.
• Asset register: List every depreciating asset purchased during the year. Date of purchase, cost, and description. Items under the instant asset write-off threshold may be expensed immediately — confirm the current threshold with your registered tax agent before assuming eligibility.
• Vehicle: Is your logbook current? The logbook must cover at least 12 weeks in a representative period. If your logbook is more than five years old and your business use has changed, start a new one now.
• Income protection insurance: Premiums on a policy covering business income are generally deductible as a business expense. Pull the annual premium statement.
• Superannuation: Sole traders can make concessional contributions to their own super and claim a deduction. The money must be received by the fund before 30 June and a Notice of Intent to Claim Deduction lodged with the fund before you lodge your return.

Week 3 (third week of June): Bookkeeping and bank reconciliation

• Bank reconciliation: Every transaction in your business bank account should be categorised. Unreconciled transactions at year-end create errors in your tax return and your BAS.
• Invoices and receipts: Every deduction needs documentation. Scan or photograph paper receipts now — thermal paper fades and receipts get lost.

If you are not already using a dedicated bookkeeping tool, this is the moment. eCashBooks is designed specifically for Australian sole traders — simple income and expense tracking, no accounting-degree required, no Xero complexity. Year-round bookkeeping in eCashBooks means your year-end reconciliation is a confirmation, not a scramble. The GoTax + eCashBooks stack gives you the complete picture: GoTax for the annual return, eCashBooks for the records that make that return accurate.

• Donations: Same rule as PAYG — DGR receipts for any charitable donations before 30 June.

Week 4 (final days of June): Equipment cut-off and finalise

• Equipment: Any depreciating asset you need for the business — tools, vehicles, computers, phones, machinery — buy before 30 June. Assets purchased before 30 June are depreciable from this year.
• Prepay deductible expenses: Some business expenses can be prepaid and deducted in the current year if the prepaid period does not extend beyond 12 months. Common examples: insurance renewals, rent, subscriptions. Confirm with your tax agent before prepaying.
• Final check: Open your bookkeeping records and look at your profit for the year. If it is higher than expected, consider whether additional super contributions before 30 June are appropriate. Super contributions reduce taxable income.

Ready to lodge? Sole traders, ABN holders, contractors, freelancers, rideshare drivers and self-employed individuals use the ABN Tax Return ($140). That fee covers registered tax agent preparation and lodgement, and the GoTax Deduction Grabber app (free) helps you capture receipts on the go throughout the year so the next June is less work.

The Mixed-Income Year-End Checklist (PAYG Plus ABN)

You earn salary or wages from an employer and you also earn income from an ABN — as a contractor on the side, a rideshare driver on weekends, a freelancer, or a small business you run alongside employment. Your return needs to handle both.

The good news: the ATO has seen your situation many times. The complexity is real but it is manageable. The key is keeping the two income streams separated in your records so nothing gets missed and nothing gets incorrectly deducted against the wrong income type.

Week 1: Separate the income streams

• Employment income: Note your salary, wages, and any allowances from your employer. These are PAYG pre-filled after year-end.
• ABN income: Reconcile every invoice and payment from your business activity. If you have not kept these separate throughout the year, do it now — go through your bank statements and categorise each transaction.

Weeks 2–3: Deductions for each stream

• Work-related deductions (employment): WFH, vehicle for work, tools and equipment, union fees, self-education — same as the PAYG checklist above.
• Business deductions (ABN): Vehicle (logbook or cents-per-km), phone and internet business-use percentage, materials, subcontractors, home office for business activity, software, income protection insurance for business income — same as the sole trader checklist above.
• Critical: Do not mix deductions. A home office claim for your employment work is calculated differently from a home-office claim for your business. They may both exist in your return, but they sit in different sections and use different bases.
• If you are registered for GST on your ABN income, your GST reconciliation runs alongside the income tax reconciliation. Make sure both are completed before lodging.

Week 4: Super and finalise

• Personal super contributions: Available if you have any self-employment income for the year. Confirm eligibility with your tax agent.
• Tax estimate: With two income streams, your total taxable income may be in a higher bracket than your PAYG withholding anticipated. If your employer withheld tax assuming your only income was the salary, you may have a shortfall. Work out an estimate now so July is not a surprise.
• Medicare Levy Surcharge: If your income exceeds the MLS threshold and you do not have private health insurance, you will owe additional tax. Check whether private hospital cover is worth the cost before 30 June.

Ready to lodge? Mixed-income taxpayers are best served by the Full Tax Return ($65) if the ABN activity is modest, or the ABN Tax Return ($140) if the business component is material. If you are unsure, complete the return and GoTax’s registered tax agents will confirm the right approach before anything is lodged.

The 30 June Moment — What to Do on the Day

30 June falls on a Tuesday in 2026. Here is what you should actually do on the day:

• Make any last super contributions. Check the fund’s cut-off time — some require processing by a certain time on the last business day.
• Make any final DGR donations. Most accept online payments 24 hours.
• Buy any equipment you need and have already decided to purchase. Keep the receipt with the date clearly visible.
• Finalise your WFH hours record if you are using the actual method. The record ends today.
• Export or download your full transaction list from your bank or bookkeeping tool. The year ends at midnight.
• Do not lodge your return today. Most income information (employer summaries, bank interest, dividend statements) is not available from the ATO until late July or August. Lodging too early risks an incomplete return.

The day itself is less dramatic than the preceding four weeks. If you have worked through the checklist above, 30 June is a checkpoint, not a crisis.

After 30 June — When and How to Lodge

The ATO opens lodgement for the 2025–26 income year on 1 July 2026. The personal lodgement deadline for most individuals is 31 October 2026. If you lodge through a registered tax agent, you may have access to an extended due date — ask your agent.

• Wait until late July or August before lodging. Pre-fill data (employer summaries, bank interest, managed fund distributions, private health insurance statements) loads progressively. Lodging in early July typically means incomplete pre-fill.
• Check your myGov account to see which items have loaded. The ATO indicates when pre-fill is available.
• Review every pre-filled item before accepting it. Pre-fill is not always complete or correct. An employer summary may be missing an allowance. Bank interest may be under-reported. You are responsible for the accuracy of your return, not the ATO’s pre-fill function.
• Add your deductions from the records you gathered before 30 June. This is where the preparation pays off.
• Lodge with a registered tax agent if your situation has any complexity: investment income, multiple employers, business income, depreciation schedules, rental property, capital gains. A registered agent reviews the return before lodgement and is professionally responsible for it.

GoTax allows you to start your return and save it as you go. Visit gotax.com.au from late July and work through your return at your own pace. Every return is reviewed by a registered tax agent before the ATO receives it.

Frequently Asked Questions

Can I lodge my tax return before 30 June?

Technically yes — the ATO accepts early lodgements — but in practice, no. Income pre-fill data from employers, banks, and investment platforms is not available until July or August. Lodging before pre-fill is loaded almost always results in an incomplete return, which may require amendment later. Wait until mid-July at the earliest and preferably until the ATO indicates your pre-fill is ready.

What happens if I miss the 31 October lodgement deadline?

If you are lodging yourself (self-lodgement via myGov), the deadline is 31 October 2026. Missing it may result in a failure-to-lodge penalty, which compounds the longer you wait. If you engage a registered tax agent before 31 October, you generally receive access to the agent’s extended lodgement schedule — which may extend your deadline to May 2027. Contact a registered tax agent before October if you need more time.

I forgot to claim something last year. Can I fix it?

Yes. You can amend a previously lodged return within two years of the original lodgement date. Lodge an amendment through myGov or ask your registered tax agent to amend on your behalf. Common forgotten items include income protection insurance premiums, union fees, and work-from-home deductions. Do not amend without the supporting receipts and records.

How do I know if a charity is DGR-registered?

Search the ABR (Australian Business Register) or the ATO’s DGR register. Only donations to organisations endorsed as Deductible Gift Recipients are tax-deductible. A charity being registered as a charity is not the same as being DGR-endorsed. When in doubt, check the register before you donate if the deduction is your primary motivation.

Do I need a separate bank account for my ABN income?

The ATO does not legally require it, but practically speaking, yes. Keeping your business income and expenses in a separate bank account makes reconciliation straightforward, prevents personal expenses from contaminating your business deductions, and makes your return faster and more accurate. If you are currently mixing accounts, open a separate one now and start fresh from 1 July.
