You will be paying a lot of tax on amounts that are not income. Federal Income Tax is based on your taxable income and Social Security and Medicare are 15.3% of your profit.
If you made more than $600 at any one establishment, they are required to issue you a 1099-Misc. You might threaten to report them.
Penalties for not issuing Form 1099-MISC
People and companies that make payments of miscellaneous income to individuals must give the payee Form 1099-MISC by the end (in most cases) of February of the year following the tax year in which the income was paid. However, if the payment is for non-employee compensation to be shown in box 7 of Form 1099-MISC, then it is required to be filed by January 31st. For example, if you received miscellaneous income in 2016 that is non-employee compensation, the paying institution or individual must issue Form 1099-MISC by January 31, 2017. If the institution fails to do so, the penalty against the company varies from $30 to $100 per form ($500,000 maximum per year), depending on how long past the deadline the company issues the form. If a company intentionally disregards the requirement to provide a correct payee statement, it is subject to a minimum penalty of $250 per statement, with no maximum.
