A surprising number of widely repeated audit 'rules of thumb' do not hold up under scrutiny.

What this means for you

The CRA's internal procedures move on fixed schedules regardless of your personal circumstances. Requesting an extension, providing documentation early, or simply acknowledging receipt in writing are small steps that create a paper trail you may need later if the file escalates.

What you can do next

  • Read the notice in full before responding to anything
  • Note every date mentioned, not just the one in bold
  • Keep a copy of everything you send, including the envelope or email header

Self-employment status alone does not meaningfully increase audit risk the way many assume.
