Choosing a name for your PAF

Once you have decided on a suitable name for your PAF, conduct a search at BizFile+ to find out whether the name is available.  Avoid selecting names which:

  • are identical to an existing entity registered with ACRA;
  • are undesirable i.e. names which are vulgar, obscene or offensive;
  • ACRA has directed the Public Accountants Oversight Committee not to accept.

Please refer to the Practice Direction No. 7 of 2006: Identical Name Prohibition of for All Accounting Entities (PDF, 143KB) for information on the principles of whether a name is similar to another.

Requirements to set up a PAF

  • If the PAF has two partners, one of you must be a public accountant.
  • If the PAF has more than two partners, at least two-thirds of the partners must be public accountants.
