<prompt> Human: I just learned that a guy I worked for 1099 in 2005 reported 40k of income I absolutely did not get paid. I still have a 20k check that he paid me but, I was unable to cash due to him waiting for the primes payment.Aside from fighting the IRS and, proving my income, what are my options? Any chance in hell of cashing or getting reimbursed for the check?I am real particular about my books and can easily prove the transactions. I have also learned that he claimed all of my expenses as well.What a low life...  <response>: You probably cant cash the check. However, if he owed you the money, you can absolutely ask him to reissue it.It does sound like the situation is more complicated than that, and legal counsel would be a good idea.
