BAS lodgement for Mandurah businesses

If your business is registered for GST, you’ll need to lodge a BAS. In most cases, small businesses lodge quarterly. According to the ATO, the quarterly BAS due dates are 28 October, 28 February, 28 April and 28 July. However, a registered tax or BAS agent may be able to give you extra time.

We prepare and lodge BAS for Mandurah tradies, cafes, retailers, health practitioners and other businesses. We also check GST, PAYG withholding and PAYG instalments, so your BAS lines up with your books. For a plain-English overview, read BAS explained.

Why use a tax agent for your Mandurah tax return?

Many people lodge their own return, and that’s fine for simple situations. However, a registered tax agent can help when things get more complex. For example, you might have business income, a rental property or several income sources.

Timing matters too. The ATO says self-lodgers must lodge by 31 October. In contrast, registered tax agents generally have special lodgment schedules. To use that, you need to engage the agent before 31 October.

Our post on why use a tax agent explains the benefits in more detail.

Tax help for Mandurah landlords and sole traders

Mandurah has plenty of residential property, so rental returns are a big part of local tax work. The ATO says landlords must keep records, declare rental income and only claim eligible expenses. It also says a property must be rented, or genuinely available for rent, on commercial terms. See the ATO’s guide to residential rental properties.

Similarly, sole traders have their own questions. For instance, when should you register for GST? The ATO says you must register for GST once your GST turnover reaches $75,000 or more. Taxi and rideshare drivers must register regardless of turnover.

Common situations we help with

Employees and new sole traders. We help with work-related claims, so you only claim the deductions you can claim. We also help new ABN holders understand when GST registration applies.

Investors and landlords. Returns can involve rental income, investment income or the sale of an asset. If you sell an investment property or shares, capital gains tax may apply, so good records of purchase and sale costs matter.

Tradies and contractors. Construction is the largest business group in the City of Mandurah. If your business is in building and construction and pays contractors, you may need to lodge a taxable payments annual report. We can help you work out whether it applies.
