How to Start a Business in NSW, Australia: Steps, Costs and Structure (2026 Guide)

Thinking about starting a business in NSW? Good news: it is simpler and cheaper than most people expect. You can go from idea to legally registered for under $50 as a sole trader, or around $636 plus extras as a company.

The tricky part is not the paperwork. It is knowing the right order to do things in, what everything actually costs, and which decisions matter (structure, name, domain, insurance) versus which ones can wait.

We help Australian service businesses get set up and growing every week, and this is the guide we wish every new owner had on day one. Every government fee below is the current 2026-27 figure, checked against ASIC, the ATO and the other official sources in July 2026 - not the stale numbers floating around older articles. Insurance, domain and professional-service costs are indicative market ranges, because those vary with your business.

Short answer: To start a business in NSW in 2026:

1. Choose your structure - sole trader (free ABN) or company ($636 ASIC fee)
2. Check your name is available - on the ASIC register, IP Australia's TM Checker, the .com.au domain registry and social media
3. Register - your ABN (free), business name ($47/year), and GST once turnover hits $75,000
4. Lock in your domain - the .com.au (~$10-$40/year) for an Australian audience
5. Check licence requirements on ABLIS
6. Sort insurance - workers compensation via icare is compulsory once you pay staff more than $7,500 a year; public liability is strongly recommended
7. Get found - website, Google Business Profile and search visibility

Registering as a sole trader can cost under $50 all up; a company typically runs $700-$2,000 in year one with professional help.

Step 1: Choose your structure - sole trader or company?

This is the first real decision, and it shapes your tax, your risk and your running costs. Here is the plain-English version.

A sole trader is you. You and the business are legally the same person. Your business profit gets added to your personal income and taxed at normal personal rates. It is free to set up, simple to run, and you keep full control. The catch: if the business owes money or gets sued, your personal assets - your house, your car, your savings - are on the line.

A company is a separate legal "person." It has its own name, its own bank account, its own tax return, and it can own things, sign contracts and take on debt in its own right. If something goes wrong, in most cases only the company's assets are at risk, not yours. The trade-off is cost and admin: $636 to register, $342 every year to ASIC, and a separate company tax return (most small business owners pay an accountant for this).

So which one? Most people start as a sole trader because it is free and fast, and that is a perfectly good call. A company starts to make sense when:

• Your profit is consistently climbing towards the higher tax brackets (advisers often mention the roughly $100,000-$150,000 profit zone as the point to review it - as your income rises past $45,000 you pay 30% plus the Medicare levy on each extra dollar, then 37% past $135,000, while a small company pays a flat 25%)
• You are signing leases, taking on debt or working on jobs where something going wrong could get expensive
• You are hiring employees
• You want to bring in a business partner or investor (a company can sell or give them ownership shares - a sole trader cannot)

One more thing for company directors: every director needs a free director ID from Australian Business Registry Services, applied for through the myID app - and you must have it before you are appointed, not after.

This is general information, not advice. The sole trader vs company call genuinely depends on your income, family situation and risk. A registered tax agent will sort it in one conversation. If you do not have an accountant yet, we happily point people to The Fox Group on the Central Coast - they look after businesses and family groups across NSW. That said, any registered tax agent can help, so go with whoever you click with.

Before you pick a name: two bits of homework. One thing every authoritative guide agrees on - including the government's own - is that market research and positioning come before naming, because a good name flows from how you plan to stand out. So before you fall in love with a name, spend a little time on who you are up against locally (what they charge, where they show up, what they miss) and on the brand you actually want to build. If you want help with this, our Competitive Intelligence report maps your market before you spend a dollar on it, and the Brand Blueprint clarifies your positioning, message and visual identity before you commit to anything. Neither is a required step - but both make every step that follows easier.

Step 2: Check your business name is actually available (everywhere)

Here is the mistake we see constantly: someone falls in love with a name, registers it with ASIC, prints the shirts... and then discovers the domain is taken, the Instagram handle is gone, or another business two suburbs over already trades under it.

Do these five checks before you commit to anything. All of them are free and take about 20 minutes total.

1. Check the ASIC business names register

Search ASIC's Check Name Availability tool to see if the name can be registered, and ABN Lookup to see who else is already using similar names. If an identical name is registered, you are back to the drawing board.

2. Check trade marks with TM Checker (optional - but worth five minutes)

You do not need a trade mark to start a business - this step is completely optional. But the check itself is free, takes five minutes, and can save you a world of pain: a registered business name does not stop someone else from registering it as a trade mark, and if someone has already trademarked your name (or something very close to it, for a similar product or service), you could be forced to rebrand later.

So run your name through IP Australia's free TM Checker - it flags clashing trade marks in minutes. And if the name really matters to you long-term, registering your own trade mark (from $330 per class) is the only thing that gives you exclusive rights to it. For most new businesses that is a nice-to-have down the track, not a day-one must.

3. Check the domain name

Search your name at any Australian domain registrar, or use auDA's official search to check every .au ending at once. If yourbusinessname.com.au is taken, seriously consider a different name - more on domains below.

4. Check social media handles

Use a free bulk checker like Namechk to scan dozens of platforms in one hit, then manually confirm on the platforms you will actually use - Facebook, Instagram, LinkedIn, TikTok. Bulk checkers occasionally get it wrong, so the manual check matters.

5. Do the Google sanity check

Finally, just Google the name (in quotes, and with "NSW" or your town added). You are looking for anyone already trading under it, ranking for it, or - worse - anyone with a reputation problem attached to it. Ten minutes here can save you a very awkward rebrand.

Only when your name passes all five checks should you spend a cent on it.

Step 3: Register everything (in this order)

Get your ABN - free

Every business needs an Australian Business Number. Apply through the Australian Government Business Registration Service - it is free and usually instant. Ignore any website that wants to charge you for an ABN; they are just middlemen adding a fee to a free government service.

Register your business name - $47

If you trade under anything other than your own personal name (sole trader) or your exact company name, you must register the business name with ASIC. Current fees: $47 for one year or $108 for three years. You can do it in the same sitting as your ABN application.

Sole trader trading as just "Sarah Nguyen"? No business name needed. Trading as "Sarah Nguyen Electrical"? That needs registering.

Registering a company - $636

Going the company route? The ASIC registration fee is $636 for a standard Pty Ltd company. You can register directly through the Business Registration Service, or have an accountant or online agent do it - typically $700-$2,000 all-in depending on who you use and what is included (things like a company constitution are worth having drafted properly). Your company automatically gets its own ACN, and needs its own TFN and ABN.

Register for GST - free, but only when you need to

You must register for GST once your turnover hits $75,000 a year - and you have 21 days once you get there. Below that, registration is optional. Registering early means you can claim GST credits on your setup costs, but you also have to add 10% to your prices and lodge BAS returns, so it is worth a quick chat with your accountant about timing.

Step 4: Lock in your domain name - .com or .com.au?

Short answer for an Australian business serving Australian customers: get the .com.au, and if the matching .com is available cheaply, grab it too and point it at your site.

A few practical notes:

• You need your ABN first. Eligibility for .com.au is checked when you register and when you renew, and the domain has to relate to your business name or what you sell. This is why domain registration comes after Step 3, not before.
• When would you choose .com instead? If you genuinely plan to sell overseas from day one, the .com matters more. For a local service business - a tradie, a salon, a gym, a consultant - the .com.au wins on trust and local search.
• Protect the brand. auDA itself recommends registering the matching versions (.com.au, .au, and .com if available) and redirecting them to your main site, so nobody can squat on them later. At $10-$40 each per year, it is cheap insurance.
• Prefer it handled for you? Domain registration and setup is something we do for clients as part of every website build - we register the right domains, connect them properly and manage the renewals, so nothing slips through the cracks.

Step 5: Check whether you need a licence

NSW does not have one general "business licence" - but plenty of specific activities need one: building work, electrical, food, beauty services using certain equipment, real estate, and many more.

The official tool is ABLIS - the Australian Business Licence and Information Service. Answer a few questions about what you do and where, and it lists every federal, state and council licence, permit and registration that applies to you. Most licences are then applied for through Service NSW, and their Business Bureau offers free personalised help for new business owners if you get stuck.

Step 6: Sort your insurance

Nobody starts a business to shop for insurance, but this is the step that saves businesses when something goes wrong. Here is what applies in NSW:

Compulsory:

• Workers compensation - if you employ staff and pay more than $7,500 in wages per year, a workers comp policy through icare is mandatory. Below that threshold most businesses are exempt, although a few industries - taxi and hire car driving, horse racing and professional combat sports - need a policy from the first dollar of wages.
• CTP Green Slip - every registered business vehicle needs one before it can be registered.
• Professional indemnity - compulsory for certain professions, including tax and BAS agents, registered health practitioners and architects.

Strongly recommended:

• Public liability - covers you if your work injures someone or damages their property. Almost every service business carries it (many commercial clients and sites will not let you through the gate without it). For a low-risk small business, cover typically starts around $400-$1,500 a year, rising with your industry risk and turnover.
• Depending on your business: tool and equipment cover, business interruption, and cyber insurance are all worth weighing up.

Our honest suggestion: consider using an insurance broker rather than guessing. A broker compares policies across many insurers, matches the cover to your actual trade and contract requirements, and goes in to bat for you at claim time - and NIBA/Deloitte industry research found many businesses were underinsured before engaging a broker. If you have no idea where to start, Rebecca Haines from All Risk Protection is a great first call for small business cover on the Central Coast and beyond - reach her on 0437 132 471 or rebeccah@allriskprotection.com.au. As with the accountant, it is your call - any licensed broker can quote you, so choose someone who takes the time to understand your business.

What it all costs: the real numbers

Here is the honest 2026-27 picture for a typical NSW service business, using current official fees plus indicative market ranges for the rest:

Two things jump out. First, becoming a legal, insured sole trader costs less than most people's phone bill for the year. Second, the company premium is real - which is exactly why most owners start simple and restructure when the numbers justify it.

(Everything above is general information based on fees current at July 2026 - registration fees index every 1 July, and your tax position is your own. Confirm the details for your situation with a registered tax agent.)

Step 7: Get found and get chosen - the growth stack after registration

Here is the uncomfortable truth: registering the business is the easy 10%. The other 90% is getting customers - and the new businesses that take off are the ones that treat the next five things as part of the setup, not something to "sort out later." Once the paperwork is done, this is the order that works:

1. A real website on your .com.au. Even a sharp one-pager beats a Facebook page alone - it is the asset you own, and it is where every quote request lands. Our custom websites are built for service businesses: fast, mobile-first and search-ready from day one, with your domain registered and connected as part of the build.
2. A free Google Business Profile. Set it up the day you register - for local "near me" searches it matters more than almost anything else, and it costs nothing.
3. Search visibility - on Google and in AI. Search has changed: customers now ask ChatGPT and Google's AI who to use, not just the old ten blue links. Our SEO & AEO Growth service is built for exactly that - making your business easier to find on Google and easier for AI assistants to understand and recommend.
4. Paid ads when you are ready for more work. Once the foundations are live, managed Google and Meta advertising is one of the fastest ways to bring in work - with proper tracking, so you can see what your leads and booked jobs actually cost you.
5. Capture and follow up every enquiry. Missed calls and forgotten quotes are where new businesses quietly bleed. This is the gap My Digital Group CRM fills: one simple system that captures every lead, follows up automatically, and keeps your reviews and bookings humming while you do the actual work.

You do not need all five on day one - start with the website and Google Business Profile, and layer the rest in as the work builds. The point is to know the roadmap, so every dollar you spend builds on the last one.
