TOPS 2222PS3 1099 Double Window Envelope 3.75 x 8.75 White 24/PK

1099 Tax-Form Envelopes

These white business envelopes are built for mailing IRS 1099-NEC forms and similar tax documents. Each pack contains 24 envelopes sized 3.75 x 8.75 inches with a commercial flap and side seam. They suit accountants, payroll departments and small businesses that send recipient copies in bulk. The preprinted front message reads Important Tax Return Document Enclosed.

Double Window Security Design

Two left-aligned windows measure 3.25 x 0.88 inches and 3.25 x 1 inches to frame the form data while hiding personally identifiable information. A security tinted pattern blocks readability when the envelope is held to light. The gummed closure creates a durable seal that runs reliably through bulk mailing machines without jamming. Wove finish paper stock gives a professional feel.

Upgrade from Plain Mailers

These replace standard unprinted envelopes that require manual addressing or separate window inserts. The jump is worth it when you process high volumes of 1099 forms and need the combined speed of machine-sealable closure, exact window alignment and built-in security tint. They are not suited for mailings that need larger inserts, non-standard form layouts or recycled-content paper.
