Add or back out 10% GST, get a rough net-GST figure for your quarterly BAS, and check whether your turnover has crossed the $75,000 registration threshold.
traqR calculates GST on every quote and invoice and gives you a BAS-ready summary, so you’re not piecing this together from a shoebox at quarter’s end.
Start free trialIn Australia GST is 10%, so the GST inside a GST-inclusive price is the total divided by 11 — not divided by 10.
On your BAS you pay the GST you collected on sales, minus the GST credits on your business purchases. The difference is what you owe (or get back).
Once your rolling 12-month turnover reaches $75,000 you must register for GST within 21 days and start charging it.
You must register once your GST turnover reaches $75,000 in a rolling 12-month period (or you expect it to). You then have 21 days to register. Taxi, rideshare and some other activities must register regardless of turnover.
For a GST-inclusive price, the GST is the price divided by 11. For example, $1,100 inc GST contains $100 of GST and $1,000 ex GST. To add GST to an ex-GST price, multiply by 1.1.
You can claim GST credits on business purchases that included GST and that you have a valid tax invoice for. Wages, bank fees, and GST-free items (like most basic food) don’t have GST, so there’s nothing to claim.
No — it’s an estimate to help you plan. Your real BAS depends on GST-free and input-taxed items, capital purchases, and any PAYG. Always confirm with your accountant or the ATO before lodging.
