Finding envelopes to fit your printed 1099 forms can be tricky. Some will show the recipient's address but not the sender's address, while others will hide parts of the addresses or worse, parts of the tax form like the personal tax number. When security is of utmost importance, these little slip-ups aren't acceptable. Our 1099 tax envelopes have a unique bottom-window design so your personal info stays hidden, and our windows are positioned to line up perfectly with both addresses. There is NO NEED to reformat your software. Our bottom window is located 1½” from the bottom, with a window height of 17/16” to prevent the federal tax identification number from showing. This bottom window is 0.5” from the left side with a window width of 33/8“ to guarantee your recipient's address will be visible without any Quickbooks reformatting. Just print and slide the form in to our secure, professional 1099 tax envelope.
