About Recipient Packages
When you print using Mail Service, your recipient packages are printed double-sided and mailed in window envelopes. Even though the print is double-sided, some forms are forced to print on the fronts of pages to comply with the printed IRS form standards.
An address cover sheet, which is formatted to fit the window envelope, is generated using the address information as it appears in ONESOURCE Trust Tax at the time of your tax return process or print request. The address a recipient package is mailed to is controlled by the recipient's address and, if applicable, the copy-to recipient's address. The return address is controlled by your fiduciary information or your 1099 or 5498 payer information.
For a package with up to 16 pages, the pages are folded and mailed in a 6" x 9" envelope. The pages are typically folded in sets of three and inserted in the envelope. This is a function of the insertion equipment and process and allows for a more efficient insertion. The pages remain in the proper order.
For a package with more than 16 pages, the pages are mailed flat in a 9" x 12" envelope. A package that is too large for a 9" x 12" envelope is mailed in a box.
Contact your Client Manager if you prefer to use only 9" x 12" envelopes for the recipient packages you print through Mail Service.
