Generally: You must issue a 1099 to any individual, estate, or, in some cases, a corporation, to whom you have paid at least a certain amount of money ($600 is the most common threshold, but it can vary depending on the type of income) for services performed in the course of your trade or business.

Specific deadlines: The deadline for issuing 1099s to your payees is January 31st of the following year. You must also file a copy of each 1099 with the IRS by February 28th (March 31st if filing electronically).

Who to issue a 1099 to: Independent contractors: This is the most common scenario. If you hire someone to perform services for your business and they are not considered your employee, you need to issue them a 1099-NEC (Nonemployee Compensation).

Other recipients: Depending on the specific type of income, you may also need to issue a 1099 to recipients of:

Interest income (Form 1099-INT)

Dividends (Form 1099-DIV)

Royalties (Form 1099-MISC)

Medical and health care payments (Form 1099-MISC)

Rent payments (Form 1099-MISC)

Fishing boat proceeds (Form 1099-MISC)

Payments from certain payment card transactions (Form 1099-K)
