Frequently Asked Questions

What is the current GST rate in Australia?
The GST rate in Australia is 10%. It applies to most goods and services. Some supplies are GST-free (basic food, medical services, exports) or input-taxed (residential rent, financial supplies). Use our GST Classifier to check any specific transaction instantly.
When is my BAS due?
Quarterly BAS due dates are 28 October (Q1), 28 February (Q2), 28 April (Q3), and 28 July (Q4). Monthly lodgers must lodge by the 21st of the following month. Tax agent lodgment schedules may have extended due dates. Check our ATO Tax Deadline Calendar for live countdowns.
How do I calculate PAYG withholding in Australia?
PAYG withholding is calculated by annualising the employee's income, applying the ATO Schedule 1 tax scale for their residency type, adding the Medicare levy and any HECS/HELP repayment, then dividing back to the pay period. Our PAYG Withholding Calculator handles all of this instantly — just enter the gross income and pay frequency.
How do I verify an ABN in Australia?
You can verify any ABN using our free ABN Lookup tool, which queries the Australian Business Register (ABR) directly. It returns the entity name, type (Pty Ltd, trust, sole trader etc.), GST registration status and whether the ABN is currently active or cancelled. Verifying supplier ABNs before payment protects you from the ATO's 47% no-ABN withholding obligation.
What is the Super Guarantee rate for FY2025–26?
The Super Guarantee rate for FY2025–26 is 11.5%. From 1 July 2026, Payday Super takes effect — employers must pay SG contributions within seven business days of each payday, replacing the quarterly payment schedule. Read our Payday Super Checklist for full preparation guidance.
Do I need to register for GST as a sole trader?
You must register for GST once your annual turnover reaches $75,000 (or $150,000 for not-for-profits). Ride-share and taxi drivers must register regardless of turnover. Use our Sole Trader Tax Estimator to check your position based on your actual income figures.
What can the Journal Entry AI Assistant do?
The Journal Entry AI Assistant takes a plain-English description of any Australian business transaction and returns the correct debit/credit journal entry — with account names, account types, GST codes (G1, G10, G11, GST Free, Input Taxed, BAS Excluded), a software-specific tip for Xero or MYOB, and a plain-English explanation. It is ideal for bookkeeping staff learning GST rules or checking unusual transactions before posting.
