Business Activity Statement (BAS) Services

Staying on top of your Business Activity Statement (BAS) lodgements is one of the most important parts of running a compliant business in Australia. Whether you're a sole trader or a company registered for GST, BAS reporting is how the Australian Taxation Office (ATO) tracks your obligations — including GST, PAYG withholding, and other taxes. Trident Accounting offers tailored BAS services for businesses across Australia, with hands-on support for those based locally in Miranda and the Sutherland Shire region of NSW.

What Is a BAS?

A Business Activity Statement (BAS) is a form submitted to the ATO on a monthly, quarterly, or annual basis — depending on your business type and GST turnover. It summarises the taxes you've collected and paid, and must be lodged accurately and on time to avoid penalties.

BAS typically includes:

  • Goods and Services Tax (GST)
  • Pay As You Go (PAYG) withholding for employees
  • PAYG instalments for your own income tax
  • Fuel tax credits (if applicable)
  • Other tax obligations depending on your industry

You can find official guidance from the ATO here: ATO – Business Activity Statements

Two BAS Service Options — Choose What Fits You

Option 1: BAS Preparation (No Data Entry)

This service is ideal if your bookkeeping is already up to date — whether you've done it yourself in Xero, MYOB, QuickBooks, or had it completed by a third party. We’ll review your accounts, verify GST coding, and prepare and lodge your BAS professionally through our registered tax agent portal.

It’s the fast, affordable way to stay compliant if your records are already clean.

Option 2: BAS With Full Data Entry & Review

Need help getting your books in order before lodging? No problem. This service includes full bookkeeping and data entry prior to BAS preparation. We'll reconcile your bank accounts, enter missing transactions, review GST categories, and ensure your financial data is accurate before lodging your BAS.

This is our most popular service for businesses that are behind, disorganised, or simply too busy to manage the accounts themselves.

Pricing

  • BAS (No Data Entry): From $80
  • BAS With Full Data Entry: From $400

Additional costs may apply if multiple periods are overdue or if accounts need full reconstruction. We’ll always give you a clear quote before proceeding.
