BAS Lodgement

BAS Lodgement Service Australia — Prepared and Lodged for You

GST reconciliation and BAS preparation handled inside your accounting software every quarter. Reviewed, authorised, and lodged — with no missed deadlines. From $249/month.

What We Do

BAS preparation and lodgement, end-to-end.

advancr handles your entire BAS process — from GST reconciliation through to lodgement with the ATO. Everything completed inside your existing accounting software, on a fixed quarterly schedule.

01
GST Reconciliation
All transactions reviewed for correct GST treatment. Tax codes verified, mixed-supply items handled correctly, and any coding errors corrected before the BAS is prepared.
03
Review and Authorisation
Your completed BAS is presented to you for review before lodgement. You maintain full visibility and control — nothing is lodged without your authorisation.
04
ATO Lodgement
Once authorised, advancr lodges your BAS with the ATO. Confirmation is provided and your records are updated — no manual submission required on your end.
05
Deadline Management
advancr tracks your BAS due dates and begins preparation well in advance of each deadline. No chasing, no last-minute scrambles, no ATO penalties for late lodgement.
06
PAYG Withholding
PAYG withholding amounts from payroll are correctly reported in your BAS each quarter. Reconciled against your payroll records to ensure the ATO figures are accurate.

Due Dates

Know your BAS deadlines.

Most Australian small businesses lodge BAS quarterly. Due dates vary depending on whether you self-lodge or use a registered BAS agent — agents receive an extended deadline.

Self-lodged BAS due dates
Q1 — Jul–Sep28 October
Q2 — Oct–Dec28 February
Q3 — Jan–Mar28 April
Q4 — Apr–Jun28 July

How It Works

BAS handled without you lifting a finger.

advancr prepares your BAS as part of your monthly bookkeeping cycle. By the time each quarter closes, your books are already reconciled and your BAS is ready to review.

Step 01
Books reconciled throughout the quarter
Your transactions are coded and reconciled every month as part of your advancr subscription. By quarter end, your GST position is already accurate and up to date.
Step 02
GST reviewed and BAS prepared
At quarter end, advancr performs a full GST reconciliation, reviews all tax codes, and completes the activity statement inside your accounting software.
Step 03
You review and authorise
Your completed BAS is shared with you for review. You check the figures, ask any questions, and give authorisation to lodge — nothing is submitted without your sign-off.
Step 04
Lodged and confirmed
advancr lodges with the ATO and provides you with confirmation. Your payment obligation (or refund position) is confirmed and your records are updated.

Common Questions

BAS lodgement — frequently asked questions.

A Business Activity Statement (BAS) is a form submitted to the ATO to report GST, PAYG withholding, and other tax obligations. Most small businesses lodge quarterly — due dates are typically 28 days after the end of each quarter, with an extension available when lodged through a registered BAS agent.

Yes. BAS preparation is included across all advancr plans. BAS lodgement is available as an add-on. advancr prepares your activity statement inside your accounting software, presents it to you for review and authorisation, then lodges with the ATO on your behalf.

BAS preparation involves reconciling your GST, reviewing your transactions, and completing the activity statement form. BAS lodgement is the act of submitting that completed statement to the ATO. advancr handles preparation as standard and lodgement as an optional add-on.

The ATO can issue a failure-to-lodge (FTL) penalty for late BAS submissions. Penalties start at one penalty unit ($313 as of 2026) per 28 days late. advancr's quarterly BAS preparation ensures your activity statement is ready well before the due date — no last-minute scrambles.

You must register for GST if your business has a GST turnover of $75,000 or more. Once registered, you are required to lodge BAS — either quarterly or monthly. Businesses below the threshold can choose to register voluntarily.
