Tax Registration in Australia
ABN, business TFN, GST and PAYG withholding registration through the ABR / Business Registration Service — all free. A company, partnership or trust needs its OWN business TFN; a sole trader uses their individual TFN. GST registration is compulsory once GST turnover reaches AUD 75,000 (AUD 150,000 for not-for-profits, and any turnover at all for taxi and ride-sourcing), and research records that registration must follow within 21 days of the threshold being crossed; GST is 10% and is remitted through the Business Activity Statement. PAYG withholding is registered before you pay employees, directors or certain contractors — and note the verified sting in the tail: a business that has not quoted an ABN has 47% withheld from payments made to it. The day window below is a Comriq delivery estimate, not an ATO service level.

These are the authority’s published lines. Which of them apply depends on your filing — a schedule by headcount, capital or entity type is one line, not all of them — and the applicable line is confirmed before payment, at cost.
