How GST works

The 10% Rule

SituationFormulaExample ($1,100)
Add GST to a priceprice × 1.1$1,000 + $100 GST = $1,100
Extract GST from a totaltotal ÷ 11$1,100 ÷ 11 = $100 GST
Price before GSTtotal ÷ 1.1$1,100 ÷ 1.1 = $1,000

GST is a value-added tax collected by the ATO. Businesses registered for GST charge it on taxable supplies, claim credits on purchases, and report the difference on the BAS.

FAQ

Common questions

호주의 GST 세율은 얼마입니까?

GST is a flat 10% on most goods and services. Some supplies are GST-free (basic food, exports, some medical and education services) and some are input-taxed (residential rent, financial services). GST is not a tax on your profit — you collect it on behalf of the ATO and remit the net amount.

Why divide by 11 to extract GST?

Because GST-inclusive prices are 110% of the pre-GST price. If the total is $1,100, the pre-GST price is $1,000 and the GST is $100 — exactly one eleventh of the total. So: GST = total ÷ 11.

What is the GST registration threshold?

$75,000 annual GST turnover for most businesses, $150,000 for non-profits. Ride-sourcing and taxi drivers must register regardless of turnover. If you register voluntarily you must stay registered for at least 12 months.

How do GST credits work?

사업용품을 구매할 때 가격에 포함된 GST는 판매 시 징수한 GST를 상쇄하는 매입 세액공제가 됩니다. BAS에 판매 및 크레딧을 보고합니다. 크레딧이 징수된 GST를 초과하는 경우 ATO는 차액을 환불합니다.

BAS에서 GST 번호는 어디에 표시되나요?

G1 = total sales, G2 = export sales, G3 = other GST-free sales, G10 = capital purchase credits, G11 = non-capital purchase credits. Net GST (label G) is GST collected on taxable sales minus total credits. Our BAS calculator works through it step by step.
