I earned a bunch of money working for my neighbor and he paid me in all cash.  What can I do to avoid having to pay taxes on that income?

If you earned income from your neighbor, you are required to report that income to the IRS, regardless of whether your neighbor paid you in cash. You should keep records of your transactions including how much money you earned, how your neighbor paid you (cash or other), and the date and amount of the payment. If you cannot obtain a valid Form W-9 from your neighbor or any other documentation, you must report the income and pay any resulting taxes on it.
