What's on a BAS?

The BAS covers several different tax obligations, depending on your business structure and circumstances. Here's what you're likely to see:

GST (Goods and Services Tax)

If your annual turnover is $75,000 or more, you must be registered for GST. When you are, you collect 10% GST from your customers and pay it to the ATO — but you can also claim back the GST you paid on your business expenses. The BAS is how you reconcile all of this.

PAYG Withholding

If you have employees (or pay some contractors), you're responsible for withholding tax from their wages and sending it to the ATO. This is reported on the BAS.

PAYG Instalments

If you're a sole trader or company earning above a certain income threshold, the ATO may ask you to pre-pay your income tax throughout the year. These instalments are also reported on the BAS.

When Is It Due?

Most small businesses lodge their BAS quarterly. The due dates are:

• Q1 (July–September): 28 October
• Q2 (October–December): 28 February
• Q3 (January–March): 28 April
• Q4 (April–June): 28 July

If you lodge through a registered tax agent or BAS agent, you may get an extended deadline — another good reason to use one.

Who Has to Lodge?

You must lodge a BAS if you're registered for GST. Even if you have no activity to report (zero turnover for the quarter), you still need to lodge a nil BAS. Ignoring it isn't an option.

What Happens If You Miss It?

The ATO takes BAS lodgement seriously. Missing a due date can result in:

• Failure to lodge penalties (these can add up quickly)
• Interest charges on any amount owed
• Increased scrutiny of your tax affairs going forward

If you're struggling to lodge on time, contact the ATO or your BAS agent before the deadline — not after.

Common Mistakes

These are the errors I see most often as a registered BAS Agent:

• Forgetting to include all income (especially cash or bank transfer sales)
• Claiming GST credits on private expenses
• Missing the GST registration threshold and not realising you should be registered
• Mixing up BAS label codes
• Not reconciling bank accounts before lodging

1. Reconcile Your Bank Accounts

This is non-negotiable. Before EOFY, every business bank account should be reconciled — meaning every transaction in your bank statement matches a corresponding entry in your accounting software. If you're behind on this, start now. An unreconciled set of books makes accurate reporting impossible.

What to check:

• All income is recorded (including cash sales, bank transfers, payment platforms like Stripe or Square)
• All expenses are categorised correctly
• Petty cash and credit card accounts are balanced

2. Chase Any Outstanding Invoices

Any invoice you issued before 30 June counts as income for this financial year — even if it hasn't been paid yet (this is called accrual accounting). That means you may be taxed on money you haven't actually received.

Two options: chase payment before 30 June so the cash is in your account, or talk to your accountant about whether cash accounting might suit your situation better.

3. Review Your Deductions

Sole traders can claim a wide range of business expenses — but only if they're properly documented. Before EOFY, go through your expenses and make sure you have:

• Receipts for all purchases (including GST)
• A log for any home office expenses
• Vehicle logbook if you're claiming motor vehicle expenses
• Evidence for any tools, equipment or subscriptions purchased for business use

Missing documentation means missed deductions.

4. Consider Prepaying Expenses

If you have cash available, you can prepay up to 12 months of business expenses before 30 June and claim the deduction in the current financial year. This includes:

• Insurance premiums
• Subscriptions
• Software licences
• Rent for a business premises

This strategy can reduce your taxable income for the current year — but talk to your accountant first to confirm it's right for your situation.

5. Tidy Up Your Asset Register

If you purchased any equipment, tools, vehicles or technology during the year, make sure they're recorded correctly in your books. Depending on the purchase price, they might be fully deducted immediately under the instant asset write-off, or they might need to be depreciated over time.

Also, if you have any old equipment that's fully depreciated or no longer in use, now is a good time to write it off.

What Is a Profit and Loss Statement?

A P&L shows the financial performance of your business over a specific period — usually a month, quarter or financial year. It tells you how much income came in, what expenses went out, and what's left over (your profit or loss).

Unlike a Balance Sheet (which shows what you own and owe at a point in time), a P&L is all about flow — money moving through your business over a period.

The Three Main Sections

1. Income (Revenue)

This is every dollar your business earned during the period — sales, service fees, interest, whatever applies to your business. This is the 'top line' you often hear about.

Look for: Is income growing month-on-month? Are all your revenue streams captured? Any unusual spikes or drops?

2. Cost of Goods Sold (COGS)

If you sell physical products, this section shows the direct costs of producing or purchasing what you sold — materials, manufacturing, freight. If you're a service business, you may not have a COGS section at all.

Gross Profit = Income minus COGS. A high gross profit margin means your core business activity is profitable before overheads are considered.

3. Operating Expenses

This is everything else it costs to run your business: rent, wages, software subscriptions, marketing, insurance, accounting fees, vehicle costs and so on. These are sometimes called 'overheads' or 'indirect costs.'

The Bottom Line

Net Profit (or Net Loss) = Income minus COGS minus Operating Expenses. This is the number most people focus on — and while it matters, it's just as important to understand how you got there.

What Good Looks Like

A healthy P&L generally shows:

• Consistent or growing income
• Expenses that are proportionate to income (not growing faster)
• A positive net profit
• No single expense category that looks out of place

What to Watch For

Common red flags in a P&L:

• Income that's declining without explanation
• Expenses creeping up without corresponding income growth
• Uncategorised or 'Miscellaneous' lines that are unusually high
• A net loss that's increasing month-on-month

Using the P&L to Make Decisions

The P&L isn't just a compliance document — it's a management tool. Use it to:

• Decide if you can afford to hire someone
• See which months are your strongest and plan cash flow accordingly
• Identify expenses you can cut
• Know whether a price increase is needed

What ChatGPT Actually Is

ChatGPT is a large language model (LLM) — an AI that's been trained on an enormous amount of text, and can generate human-sounding responses to almost any question or instruction you give it.

It's not a search engine. It doesn't browse the internet in real time (though the paid version has some browsing capability). It generates responses based on patterns learned during training — which means it's brilliant at writing and editing text, summarising information, brainstorming ideas, and explaining complex topics simply. But it can also make mistakes and confidently state incorrect facts, so always verify important information from a reliable source.

Practical Ways to Use It in Your Business

Emails and Communication

This is where ChatGPT shines for small business. Give it a rough draft of an email (or just describe what you need to say), and it can turn it into something polished and professional in seconds. Use it for client follow-ups, overdue invoice chasers, welcome emails, responding to difficult enquiries, and social media posts.

Writing and Content

If you need website copy, a bio, a product description, or blog content — ChatGPT can produce a strong first draft. You'll still need to review and edit it (always!), but it saves hours of staring at a blank page.

Explaining Complex Topics

Ask ChatGPT to explain GST, PAYG or superannuation in plain English for a client, and you'll often get a clear, accurate summary that you can then adapt. This can save significant time in client communications.

Admin and Processes

Ask it to help you write a standard operating procedure, create a checklist, or draft a client onboarding document. It's surprisingly good at structured administrative tasks.

How to Get Better Results

The single biggest mistake people make with ChatGPT is being too vague. The quality of the output is almost entirely determined by the quality of the input — the prompt. Good prompting basics:

• Be specific ("Write a 150-word professional email" beats "Write an email")
• Give context ("I'm a bookkeeper in Australia working with small business clients")
• Specify the tone ("Professional but warm, not formal")
• Ask it to adjust if the first response isn't right ("Make it shorter" or "Use more casual language")

What NOT to Put in ChatGPT

Never input full names, addresses or personal details of your clients, tax file numbers, bank account details or financial records with identifying information, or sensitive business information you wouldn't want shared externally. Treat it like you would a public website — if you wouldn't post it publicly, don't paste it in.

1. ChatGPT (OpenAI)

Best for: General writing, emails, client communication, brainstorming

ChatGPT remains the go-to for most small business owners. The free version is capable; the paid version (Plus at around $25 AUD/month) is significantly better for complex tasks. It's the most versatile AI writing tool available.

2. Claude (Anthropic)

Best for: Long documents, nuanced analysis, reading contracts or reports

Claude excels at handling large amounts of text — paste in a lengthy contract, policy document or report and ask it to summarise, identify risks, or explain in plain language. Many business owners find Claude's responses feel more thoughtful and less prone to confidently wrong answers.

3. Canva AI (Magic Studio)

Best for: Visual content, social media graphics, marketing materials

Canva has integrated AI tools throughout its platform — including AI image generation, background removal, and Magic Write for copy suggestions. If you're already using Canva (which most sole traders are), the AI features are already there. Just look for the Magic icon.

4. Otter.ai

Best for: Meeting notes, transcription

Record a client meeting, upload the audio (or connect to Zoom), and Otter.ai will transcribe it and generate a summary with action items. An enormous time saver for service businesses that do a lot of client calls.

5. Notion AI

Best for: Knowledge management, process documentation, notes

Notion is a powerful all-in-one workspace, and the AI add-on lets you generate summaries, action lists, and structured documents from messy notes. Great for building SOPs and client documentation.

6. Descript

Best for: Editing video and audio content

If you're creating video content for your business, Descript lets you edit video by editing the transcript — delete words from the text and they disappear from the video. Great for YouTube, social media or online courses.

7. Grammarly

Best for: Professional writing, proofreading

Grammarly has expanded well beyond grammar checking — it now offers tone suggestions, rewrites and style improvements. The free version is solid; paid unlocks more powerful features.

8. Tidio

Best for: Customer service, website chat

Tidio combines live chat with AI chatbot capability. For sole traders who can't be available 24/7, a basic AI chatbot can answer common questions, collect leads and direct enquiries even when you're not at your desk. Plans start free.

9. Zapier (with AI)

Best for: Automating repetitive tasks between apps

Zapier connects your apps and automates workflows without any coding. With AI features built in, you can set up automations that include AI-generated responses or content — for example, automatically drafting a personalised reply when a contact form is submitted.

10. Microsoft Copilot

Best for: Microsoft 365 users — Word, Excel, Outlook, Teams

If you're already in the Microsoft ecosystem, Copilot adds AI across the entire suite. Draft emails in Outlook, summarise documents in Word, build formulas in Excel. Requires a Microsoft 365 subscription plus the Copilot add-on.
