Who becomes a tax revenue agent? Someone who is smart, organized, and loves working with numbers. In this job you'll be a government watchdog at the local, state, or federal level making sure that people and corporations file correctly. Your most important task will be reviewing returns, so you'll need to keep track of changes in tax law, which can be as time-consuming as the job itself. Tax agents also issue refunds, collect payments, and conduct audits and investigations that may involve face-to-face meet-ups. As you advance in your career, you'll likely choose an area of expertise like assisting with criminal investigations or working with a certain type of corporation. (Along with making your job more interesting, this will probably bump up your salary—score!) Once you get over the fact that you're the person no one ever feels like hearing from, you'll be able to appreciate just how challenging and essential this job is.
