Pros
The work of a Tax Examiner in Error Resolution is really OK. Not tedious. The IRS computer does much of the work for you. It will flag something on the return that seems to be a problem. Your job is to correct the error and send a computer-generated form letter to the taxpayer, if needed. The most common kind of error is a transcription error, typically numbers have been transposed. These errors are easy to correct. For errors that you can't figure out, you mark the return as one that needs further review by a more experienced examiner and move on. The job does not involve much typing. There is generally overtime available for those who want it if they have attained the necessary proficiency. Pay and benefits are OK. The above comments apply to my particular job, of course -- an ERS (Error Resolution) Tax Examiner at one of the large service centers (Austin, Fresno, or KC). The Tax Examiner, job title encompasses many different kinds of jobs. Some involve much more interaction with taxpayers.
Cons
Workload is heavy and the job is seasonal. You will get laid off for several months of the year. This could be a good thing, of course. Depends on what you're looking for. It's difficult to attain the needed speed. If you don't get up to speed fairly quickly, you will be terminated.
