Hills District Small Business Tax FAQ

This is the question we field most often from newer Hills District operators, and the answer comes down to turnover. You are required to register for GST once your business turnover hits $75,000 or more across any rolling 12-month period — or as soon as you reasonably expect to reach it. Because the test is rolling rather than tied to the financial year, a strong few months of work in Castle Hill, Norwest or Baulkham Hills can push you over before the books show it, so it pays to watch the running total rather than waiting for 30 June.

A handful of activities, such as taxi and rideshare driving, must register from the very first dollar regardless of turnover. Below the threshold, registration is optional. Some businesses choose to register voluntarily — for instance, when most customers are themselves GST-registered and can claim the credit, or when claiming input tax credits on early start-up costs is worthwhile. Once you are registered you add GST to your taxable sales, claim credits on your business purchases, and report the net position on your BAS.

• Compulsory at $75,000 turnover over a rolling 12-month period
• Some activities (taxi, rideshare) must register from the first dollar
• Voluntary registration can suit B2B businesses or heavy start-up costs
• Registration brings ongoing BAS reporting, so weigh it deliberately

Structure is the decision new owners most often get wrong by defaulting to whatever a friend did. A sole trader is the simplest path: low cost to set up, minimal compliance, and business profit taxed at your personal marginal rates. The trade-off is that there is no legal line between you and the business, so you are personally liable for its debts. For a low-risk side venture or a business in its first tentative year, that simplicity is often exactly right.

A company is a separate legal entity. It limits your personal liability, is taxed at the company rate, and lets you retain profits in the business rather than having everything flow to you each year. Those advantages come with higher setup and annual compliance costs, ASIC obligations, and rules such as Division 7A that govern how you can take money out without triggering a deemed dividend. A trust is a third option that some Hills District family businesses use for flexibility and asset protection.

The honest answer is that the right structure depends on your profit level, your risk exposure, who else is involved and where you are heading. Many businesses start as a sole trader and revisit the question as they grow. If a company looks likely, our guide to the company tax return shows what the ongoing obligations actually involve, and we are happy to model the comparison against your real numbers.

Once you are registered for GST, the Business Activity Statement becomes a regular fixture — usually quarterly for a small business. On it you report the GST you collected on sales and the GST you paid on purchases, and you either pay the difference to the ATO or receive a refund. Quarterly statements are generally due 28 days after the quarter ends, and lodging through a registered agent typically buys a little extra time. The single biggest favour you can do yourself is keeping the bookkeeping current through the quarter rather than scrambling at the deadline.

PAYG comes in two flavours that are easy to confuse. PAYG withholding applies when you employ staff: you hold back tax from their wages and report it through the BAS or an IAS. PAYG instalments are separate — they are pre-payments toward your own income tax, which the ATO sets once your business income reaches a certain level, and which are credited against your final bill at year end. They are not an extra tax, simply your tax paid in stages.

For businesses that would rather hand the quarterly cycle off entirely, we set out how we manage it on our BAS lodgement page, and ongoing financial oversight sits within our virtual CFO service.

If you have staff, super guarantee is compulsory and the deadlines are not flexible. You must pay a percentage of each eligible workers ordinary time earnings into their chosen fund by the quarterly due dates. Pay late and the contribution is no longer deductible, and you become liable for the super guarantee charge, which includes the shortfall plus interest and an administration component. It is one of the costlier mistakes a small business can make, so it is worth treating super as a hard deadline rather than a flexible one.

A common trap is assuming contractors are always exempt. Where a contractor is paid mainly for their own labour, they can be treated as an employee for super purposes, so each arrangement deserves a quick check rather than a blanket assumption. Getting this right at the start of an engagement saves a painful catch-up later.

For yourself, it depends on your structure. A sole trader is not required to pay super for their own benefit, although personal contributions can be a tax-effective way to build retirement savings and may be deductible within the contribution caps. If you run a company and draw a wage, the business generally has to pay super guarantee on that wage just as it would for any other employee. Planning your own contributions alongside the business position is one of the practical things an accountant can help map out.

Good records are the quiet foundation under everything else — they support your deductions, make BAS and tax time faster, and protect you if the ATO ever asks questions. You need to keep records that explain all transactions relevant to your tax and super obligations: sales and other income, expenses and purchases, payments to workers, asset purchases, and any GST. In practice that means tax invoices, receipts, bank and card statements, payroll and super records, and your accounting file.

Most records must be kept for at least five years from when you prepared or obtained them, or from when the transaction was completed, whichever is later. Some records — particularly those tied to assets and future capital gains — need to be kept longer, because you may need the original cost details years down the track when you sell. Records must be in English or readily translatable, and you must be able to produce them on request.

Cloud accounting software makes day-to-day record keeping dramatically easier, and we encourage Hills District clients to use it, but the legal obligation to retain the underlying documents still sits with you. A tidy file through the year is also what turns a stressful, expensive year end into a quick one.

Plenty of very small operators run their own bookkeeping and lodge simple returns themselves, and while things stay straightforward that can be perfectly sensible. The calculus shifts as complexity arrives: registering for GST and starting the BAS cycle, taking on staff and the super obligations that come with them, weighing a move from sole trader to a company or trust, buying significant assets, or simply finding that compliance is eating hours you would rather spend on the business itself.

The real value of an accountant usually sits before the deadline, not at it. Choosing the right structure, timing a major purchase, planning contributions and reading the trade-offs between a tax decision and a cash-flow one are where good advice pays for itself. Compliance done well is the floor; planning is the upside.
