Depending on how you got paid, you may have to file form 1099 with your taxes. From the IRS' website:
Payers use Form 1099-MISC, Miscellaneous Income, to:
- Report payments made in the course of a trade or business to a person who's not an employee or to an unincorporated business.
- Report payments of $10 or more in gross royalties or $600 or more in rents or compensation. Report payment information to the IRS and the person or business that received the payment.
General instructions for filling out Form 1099 (and various others) are availabel at: https://www.irs.gov/instructions/i1099gi/index.html
