The answer to your question is no. What agents are paid is publicly disclosed, and is based on your GS level and locality. Here is the table.
https://www.opm.gov/policy-data-oversig ... l-schedule You have zero experience conducting an IRS audit according to IRS procedure. Let’s say you fangled yourself up to GS-13. It’s still below the salary you stated.
Just slide your finger across GS-13 and GS-14. That’s the max salary for an agent.
Same for managers or any other government employee. Salary is publicly disclosed, look up the max.
And realize that without IRS procedure experience, you are not max. Occasionally they bring a lawyer or someone with international experience in at GS-14, but that’s rare.
They can bring in someone with a truly niche area- like international, or estate and gift tax, or an engineer or an economist, or Counsel, or IT, and everyone will be ok with that.
But if they bring in someone who doesn’t know procedure (it takes 2-5 years to learn) for regular federal tax and don’t offer the positions to people who actually know what they are doing- that will not go over well. They will probably open it up both internally and externally, shove all the internal (more qualified) people into appropriate spots, fill some with external experienced hires, and then hire a TON of newly graduated accountants in a 3 year GS-9-11-13 track. They can purchase 4 newly hired GS-9s for one experienced GS-13. And makes sense to do so because- a) the first year attrition rate is HIGH and so is the second and third and fourth year and b) they don’t want people for 2-4 years. You will barely know procedure at the end of 3 years, they want you for 30-40 years.
