salary at a Big 4 advisory arm much higher than in the accounting arm?

I am asking because I was under the impression that a Sr. Audit/Tax Associate would make anywhere from 65k to 80k (assuming in a major market), but the same level position in advisory could pay anywhere between 100k to $120k. Is this more or less correct?

I don’t work at a Big 4 firm but based on my experience in advisory that sounds about right. At that level of seniority all-in pay can actually be considerably higher than 100-120k (based on my time at a specialist firm), but we had much higher billing rates than our competitors at Big 4 advisory arms. It does make selling work more difficult due to the higher cost, but if you’re able to justify it then the payoff is better.
