GST for engineers
Engineering and technical consultancy services are taxable, commonly at 18% GST, once you are registered and above the turnover threshold. Registered engineers quote a SAC code on the invoice. Below the threshold you can issue a plain fee invoice — this tool supports both and defaults to non-GST. Confirm your position with a tax professional.
