I'll relate my somewhat relevant experience from being recruited by potential employers during my senior year of college for soon to be Accounting and Finance grads. This was almost 30 years ago, so take it with a grain of salt.
The "Big 8" (as they were known then) accounting firms were the most aggressive in recruiting potential graduates, as were major corporations in the area and state. Many of my fellow classmates were more interested in joining private industry rather than be an auditor for a massive CPA firm, which was my path. The IRS was also recruiting accounting grads, but no virtually no one wanted to work for them. The pay was nowhere what private industry does and probably still isn't.
While some of the accountants I've know through the years might own firearms, the overwhelming majority aren't the pistol packing type. And carrying a firearm isn't really a perk for the gig that would entice college grads or even seasoned professionals.
My personal suspicion is this isn't really going to be a massive hiring spree of tax auditors, but more of a compliance bureau by these new asinine ESG and DEI regulations that big companies are starting to follow.
