Ensure immediate attention! Double-window envelopes come preprinted with the statement "Important Tax Return Document Enclosed".

Here is double window envelope for 4-Up horizontally arranged 4-Up tax forms W-2 that are on offer at our web store. We ensure that the window envelopes meant for the tax form are a perfect fit and accommodate the form inside in a way that the relevant portions are clearly visible from outside.

Window envelopes are indeed very convenient to have when you are mailing hundreds of tax forms after a tax year ends. Most tax forms have to be mailed by January end so that recipients have at least two months to prepare and file their annual income tax returns. Determine the quantity you require and place your order in one go because large orders provide cost benefits.
