How To Prepare Taxes For A Business In Australia
Tax time arrives every year, yet plenty of business owners still find themselves digging for receipts in late October. The good news is that preparing your business taxes is far less stressful when you know the steps, keep the right records, and start before the deadline looms. This guide walks you through exactly how to prepare taxes for a business in Australia, in plain English, so you can lodge with confidence and pay no more tax than you owe.
We are registered tax agents in Perth, and we have walked thousands of small business owners through this process. Whether you plan to lodge your own tax return or hand it to a qualified accountant, the groundwork is the same, and getting it right early makes everything that follows simpler.
Why Good Preparation Matters
Rushed tax preparation costs money. Miss a deduction and you pay more tax than you owe. Get a figure wrong and you risk a query from the ATO. Leave it to the last minute and you forfeit the calm needed to make smart decisions about your income and expenses.
Preparation also saves time. When your records are organised, your tax return comes together quickly, whether you do it yourself or work with a tax agent. The aim of this guide is simple: to turn a yearly scramble into a quick, repeatable process that protects your refund and your sanity.
Understand The Key Tax Dates
Timing shapes everything in tax. The Australian financial year runs from 1 July to 30 June, and the standard deadline to lodge your tax return is 31 October if you are doing it yourself. Lodge through a registered tax agent and you often qualify for a later due date, which buys valuable breathing room.
Most income information is pre-filled by the ATO by late July each year, so lodging too early can mean missing data that arrives after you have filed. A short wait often means a more accurate return.
Plan Around The Financial Year End
Some of the best tax moves happen before the income year closes. Purchasing work equipment or tools before 1 July can bring a deduction forward into the current year. You can also bring forward deductions or defer income to manage which tax bracket you land in. A quick chat with a professional in May or June often pays for itself many times over.
Gather Your Income Records
You cannot prepare a return without knowing what came in. Start by collecting every source of business income, plus any other income that affects your position.
Business And Employment Income
Pull together your sales records, invoices, and bank statements that show money received through the financial year. If you also earn wages from employment, your employers report that through Single Touch Payroll, and it usually appears pre-filled. Include any government payments, allowances, and amounts from government agencies that count as income.
Interest, Dividends And Investments
Collect records of bank interest and dividends, since these are taxable too. If you hold investments to earn interest or dividends, the related investment expenses may be claimable. Health funds also report your private health details, which can affect your return, so have that information ready.
Organise Your Deductions And Expenses
This is where good records turn into real money back. A legitimate deduction lowers your taxable income, which lowers your tax. The test is simple: an expense must relate to earning your income, and you generally need a receipt to prove it.
Work Related Expenses
Common work related expenses include tools, equipment, work-related clothing if it is compulsory, professional memberships, and self-education expenses related to your job or occupation. You can claim up to $300 in work-related expenses without receipts, but any claim over $300 requires written proof, so keep those receipts.
Working From Home
If you run the business from home, you can claim a portion of your running costs. The ATO allows a fixed rate of 70 cents per hour for hours worked from home, covering things like electricity and internet, provided you keep a record of your hours.
Everyday Business Costs
Operating expenses such as software subscriptions, insurance, interest on business loans, accounting fees, and equipment are all deductible when they relate to earning income. Scan and file your receipts and invoices electronically through the year, and tax time becomes a matter of minutes rather than days.
Keep Accurate Records All Year
The single biggest favour you can do your future self is to maintain clean records as you go. Digital tools like the ATO app make tracking expenses easy, and most accounting software will categorise transactions automatically.
Keep receipts, invoices, and bank records for every claim, and store them electronically so they are easy to access at an appointment or when you lodge. Tracking deductible expenses throughout the income year, rather than scrambling in October, is the difference between a frantic deadline and a calm one. For small business accounting done properly, organised records are everything.
Choose How To Lodge
Once your records are ready, you have two main paths, and the right one depends on your personal situation and how complex your affairs are.
Lodge Your Own Tax Return Online
You can lodge online using myTax, which is free and easy to use. You will need a myGov account linked to the ATO, and you can lodge via computer, smartphone, or tablet. Returns lodged with myTax are generally processed within two weeks. Always review the pre-filled ATO information against your own records, since most information is pre-filled but not always complete, and double-check personal details for accuracy before you submit.
Work With A Registered Tax Agent
If your business has partnerships, employees, or anything beyond the basics, professional advice usually pays off. A registered tax agent can prepare and lodge for you, find deductions you might miss, deal with the ATO on your behalf, give you a later lodgement date, and offer year-round support as your business and your life change. Our tax accountants handle the detail so you can focus on running the business.
Tax Preparation By Business Structure
How you prepare depends a little on your structure. A sole trader reports business income in their own tax return at individual rates. Partnerships lodge a partnership return, then each partner reports their share in their own return. Companies lodge a separate company return and are taxed at the company rate, while trusts add another layer again.
The records you gather are similar across all of them, income, expenses, receipts, and invoices, but the forms and the way tax is calculated differ. For example, a partnership splits profit between partners, which changes each person’s result. If you are unsure which rules are applicable to your setup, a quick word with a qualified accountant clears it up fast and keeps you compliant from day one.
Your Business Tax Preparation Checklist
A simple checklist keeps the whole job on track. Before you lodge, make sure you have gathered your income records, sorted your receipts and invoices, and listed every applicable deduction. A tradie would tick off tools, vehicle logbooks, and protective clothing, while a consultant might focus on software, home office hours, and professional memberships.
Next, verify your pre filled ATO data against your own records and confirm your personal details. The ATO app and its free how to videos walk you through any step that stumps you. It also helps to estimate your likely refund or bill early, so there are no surprises, and to understand how your tax is calculated across the brackets. Working through a checklist like this each year will save time and spare you the 10pm scramble before the deadline.
What Good Tax Preparation Reveals
Here is something most guides skip. Preparing your taxes properly tells you how your business is actually travelling. When the records are clean, patterns jump out. You see which months carry you and which ones bleed cash, which customers pay on time and which drag their feet, and whether your margins are quietly shrinking.
We have sat across the desk from owners who went quiet realising a flat-out year had barely broken even, and others who grinned when the numbers said they could afford to hire. Handled well, tax time is the one moment each year you look honestly at the whole picture. That insight beats the refund.
Common Mistakes To Avoid
A few errors come up again and again. Mixing personal and business spending muddies your records and your claims. Guessing at deductions instead of keeping receipts invites trouble. Forgetting to review last year’s tax return means repeating missed deductions. And lodging in early July, before your data is pre-filled, leads to amendments later. Avoid these four and you are most of the way to a clean return.
Case Study: A Mount Hawthorn Cafe Owner
A cafe owner in Mount Hawthorn came to us having lodged her own returns for two years through myTax. She was organised, but she had been guessing at her working-from-home hours and had never claimed depreciation on her coffee equipment or the interest on her fit-out loan.
We rebuilt her records, applied the correct home-based business method, and captured the equipment and interest deductions she had missed. Her refund came back noticeably larger, and just as importantly, we set her up with a simple system to track receipts and invoices through the year. The following tax time took her an afternoon instead of a fortnight.
Frequently Asked Questions
Business owners ask us the same questions every year, so here are clear answers. Anything else, just ask.
When Is The Business Tax Return Due?
For individuals and many small businesses lodging their own return, the due date is 31 October, covering the financial year to 30 June. Lodging through a registered tax agent usually earns you an extension, which gives more time to prepare a thorough, accurate return.
Can I Prepare My Own Business Tax Return?
Yes. Sole traders and simple businesses can lodge online through myTax with a myGov account, free of charge. That said, once you have partnerships, employees, or significant deductions, a qualified accountant often saves more than the fee through deductions found and mistakes avoided.
What Records Do I Need To Keep?
Keep receipts, invoices, bank statements, and records of income and work-related expenses. You can claim up to $300 in work-related expenses without receipts, but anything above that needs written proof. Storing everything electronically through the year makes preparation painless.
How Long Does A Refund Take?
Most tax returns lodged online are processed within about two weeks, though timing depends on the ATO and your circumstances. Accurate records and a complete return are the surest way to keep your refund moving.
