i worked on a dairy farm and got paid under the table since i started there. employment ended approx. 20min ago. i read online that he has to pay all sorts of taxes, etc. for employees. and the guy never asked for my social security number. and from my personal understandings he has been running his farm like this for years.
What he has done is clearly unlawful. He is obligated to withhold taxes for employees, etc. The question is whether you paid taxes on the income. To be completely lawful, he should have withheld social security and income taxes and you should have paid taxes on your gross income. If either of those did not happen, and it appears he did nothing, the law has been violated. Although I would encourage you to get your own taxes taken care of if you have not done so so that you are compliant, if you elect not to do that you could elect to report him to the IRS and possibly the Department of Labor. One of the losses to you and others here is you are not gaining Social Security credit which you will regret come retirement time.
