Final answer:
The 1099s are required to be filed for services rendered by independent contractors.
Step-by-step explanation:
According to IRS regulations, businesses are required to file 1099-MISC forms for services rendered by independent contractors. Therefore, the correct answer to your question is option d. Independent Contractors. When a business hires an independent contractor to perform services, and the total payment for the year is $600 or more, the business is required to report the payments on a 1099-MISC form and provide a copy to the independent contractor.
It is important to note that the other options mentioned (a. Sole Proprietorship, b. LLC, c. Corporation) are business entities but are not required to file 1099s for services rendered. Each of these entities has its own tax reporting requirements, but 1099 filing is specifically related to payments made to independent contractors.
