The 1099 is an information return that you send to the United States Internal Revenue Service (IRS). What type of 1099 you need to file depends upon what the payment to the IRS is for. Any person within the United States -- including corporations, partnerships, individuals, estates and trusts -- who make reportable transactions during a calendar year must report these to the IRS and those with 250 or more of these files must do so electronically.
Items you will need
Write the names and addresses of the business employees you are sending the 1099s to with the pencil or pen onto the middle of the envelopes.
Stamp each envelope in the top-right corner, and write a return address, if desired, in the top-left corner.
Insert the necessary 1099 documents, such as a "1099-MISC" for miscellaneous income, into each envelope and insert any additional correspondence the employee may need, such as an explanation for why the employee must fill this form out for your business.
Seal and mail out each envelope to your business' employees at least a month before the forms are due; for example, if a specific 1099 is due April 24, then ensure the 1099s are mailed to your employees before March 24 to ensure they have enough time to properly fill them out.
Employee or Individual
Fill out the 1099s you either received from your employer's business or have to file, such as a "1099-MISC" for miscellaneous income or a "1099-R" for an annuity.
Insert the 1099's into separate envelopes, if necessary, and seal each one. Place a stamp in the top-right corner of each envelope.
Write out the proper address for the IRS in the middle of the envelope; for example, if you live in Alabama, Arizona, Arkansas, Connecticut, Delaware, Florida, Georgia, Kentucky, Louisiana, Maine, Massachusetts, Mississippi, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, Texas, Vermont, Virginia or West Virginia, or your legal residence or business is outside the continental United States, then you must file to this address:
Department of the Treasury Internal Revenue Service Center Austin, TX 73301
Write out the other proper address for the IRS in the middle of the envelope; if you live in Alaska, California, Colorado, District of Columbia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Maryland, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, North Dakota, Oklahoma, Oregon, South Carolina, South Dakota, Tennessee, Utah, Washington, Wisconsin or Wyoming, then file to this address:
Department of the Treasury Internal Revenue Service Center Kansas City, MO 64999
Write a return address, if desired, in the top-left corner of the envelope, and mail it out, ensuring it is postmarked before it is due; for example, if your specific 1099 is due before April 28, then ensure it is postmarked before that date so that it will get to its destination on time.
