At the bottom of IRS Form 1040 and its relatives, there is a field for "Occupation".
I can think of a lot of different words I could use to describe my occupation. Are there any requirements or guidelines for how I should decide what to put?
How does the IRS use this information, if at all?
This forum discussion suggests the answers are "it really doesn't matter" and "they don't", but it doesn't seem authoritative.
The only use I can imagine is that if you write down an occupation that typically has a very high income ("railroad tycoon", "oil baron", "international crime lord"), and then report a tiny income, it might make you more likely to be audited.
(Note: I am not referring to the "Principal Business" field on Schedule C, lines A and B.)
