<human>: Can you succinctly summarize the text in 1-3 sentences?

So my wife started a job as a painting instructor at one of those studios where you schedule a party, BYOB, and an instructor will teach you how to paint a painting of your choice. She gets paid in cash by the owner after each party. Since it seems she is going to be paid under the table, what options are available to us for dealing with the situation? Ideally, we would like to stay on the good side of the IRS. Should we report the cash income? From what I read reporting cash income requires lots of documentation and invites an audit on those involved, and I'd rather not be punished for our honesty.

She will make about 1-2k per year doing this a couple weekends a month. She is a payroll employee at a "real" job, she just teaches painting as a side gig.
<bot>: Wife payed cash under the table, how do we stay on the Tax Man's good side without lots of hassle?
