I'm a sole trader who is about to go over $75k income for this tax year. I'm not registered for GST and so have not been charging/adding it to my invoices.

Once I've registered, will I only owe GST for invoices sent from the date I registered (that have GST added), or will I owe GST for all income prior, up to the $75k, that I did not charge my customers GST for? If so that'll be a huge bill I cant afford.

Thank you in advance.

Hi,

you will owe GST only on the invoices you issue after the registration.

One important thing to note is that turnover for GST registration is not checked by tax year, it is assessed by looking back and forward 11 months + the current month. Details here
