BAS & IAS Lodgements

Get Expert Help With Your BAS & IAS Lodgements

Lodging your Business Activity Statements (BAS) or Instalment Activity Statements (IAS) accurately and on time is crucial to staying compliant with the Australian Taxation Office (ATO).

At Byrnes Accounting & Financial, we provide dependable BAS and IAS services to businesses across Tamworth and the North West NSW region.

Hassle-Free Expert Compliance

Businesses registered for GST must prepare and lodge BAS statements periodically. An Instalment Activity Statement (IAS) is used by taxpayers who are not registered for GST. Byrnes Accounting can prepare your BAS and IAS statements and lodge these with the ATO on your behalf.

BAS Preparation and Lodgement

We take care of all GST, PAYG instalments, PAYG withholding, and other required items to ensure your business activity statements are complete and submitted on time.

IAS Preparation

For businesses not registered for GST, we help you meet your PAYG instalment and withholding obligations with accurate and timely IAS lodgement.

ATO Compliance Support

We stay up to date with ATO requirements so you can stay focused on running your business with confidence.

MYOB Partner Integration

As a certified MYOB Partner, we can work directly with your accounting software to ensure smooth, efficient reporting and lodgement.

Caddy Tindall
Mark and his team are not your normal accountants. I deal with many accountants in my business as a business coach. Mark spend the time to really understand his clients’ businesses and what they want to achieve. He helps them with the decision making in the business - not just how to pay less tax. And he is proactive - how to make the most of next year, not just what’s already happened. You’ll be crazy not to get them a go.
