Corp tax - pushing the envelope on deductions
Speaking around to my network of people who have corps for their professional consultancies (single person), concensus seems that all of their tax preparers go very high on business deductions (all sorts of personal/living expenses). I'm hearing it's not uncommon for 60-80% of their income to get offset by deductions, and scarcely a worry about CRA audit because audits are so rare ("don't mess with HST and payroll taxes and you'll be low risk of audit").
Is this in line with what tax pro's are seeing?
I've read the CRA's guidance on business deductions and I can't get to 60-80% of reasonable deductions for a full-time knowledge worker who's mostly working online from home.
Edit: I used income as sub for revenue, so yes business deductions of 60-80% of revenue. Think knowledge worker billing $200-300k annually and claiming deductions of $100k-200k, writing off all sorts of stuff. I've heard it from enough different sources to believe it. Looking for comments from tax pro's who have incorporated white collar clients on their views of (1) do they see this happening and (2) audit history
