Registered and Reliable Local Hornsby & Sydney Bookkeeper and BAS Agent

BAS Made Simple.

Whether you’re a sole trader or running a Pty Ltd, we get your data clean, your lodgements on time, and the ATO off your back.

Quarter 1 Deadline

If you lodge your own BAS, your Quarter 1 payment and paperwork are due to the ATO by 28 October 2026.

Need more breathing room? Working with a registered agent like Organised Bookkeeping automatically pushes your lodgement and payment deadline out to 25 November 2026

The 3 Rules of BAS Success

Snap Receipts as You Go: Don't work in the past! Leaving receipts to end-of-month & EOFY means lost GST tax credits and potential audit nightmares. Can you remember what you spent that $95 on last week?
Right Setup, Correct Tax: Are you a Sole Trader or Company Director? Knowing your entity structure dictates how you pay yourself, what you can claim, and whether you need a Director ID.
Know Your Obligations: The GST you collect and the PAYG you hold back for staff aren't yours to spend. Stay on top of what you owe early so you aren't stressed when tax time hits.
