Check if the practice ABN is registered and active on abr.business.gov.au.
Check the TAN is present and valid on tbp.gov.au.
If the TAN is registered, check the name used for the TAN matches the name listed against the practice ABN on abr.business.gov.au.
If the all of the above is correct, check that the ABN entered in the return is also correct.

If this is still an issue contact the ATO on 13 28 65. For the fast key code, see here.
