No. A company must have its own unique ABN. You cannot use the ABN registered to you personally as an individual/sole trader or for a partnership.
Once your company has been registered you can apply for an ABN. You can add on an ABN through our company registration form to simplify the process. You can also apply for a TFN, GST and PAYG in the same application.
If you have changed your business structure eg/ from a sole trader to a company, you will now trade under the company ABN and will not need the ABN linked to your sole trader business.
You can cancel the redundant ABN via the ABR website online or by lodging a paper form.
