A 1099 form reports income you received that wasn't withheld for taxes—money from freelance work, rental properties, investment accounts, or other sources outside a traditional job. The IRS requires businesses and financial institutions to send you a 1099 when you earn above certain thresholds, and they send a copy to the IRS too. Understanding which forms you'll receive and what they mean helps you report income correctly on your tax return.

These articles answer the questions people ask most about 1099s: what different 1099 types report, when you should receive them, what to do if one arrives with wrong information, and how to handle situations where you expected a 1099 but didn't get one. You'll learn how 1099 income flows into your return and what records you need to keep.
