Should I Staple Or Paperclip My Tax Return?

When It Makes Sense

• Good fit: You are mailing a short, single‑page return to the tax authority and want a fast, secure closure. A single staple keeps the pages together without adding bulk.
• Good fit: You are preparing a multi‑page return that will be scanned electronically. A paperclip allows the scanner to feed pages smoothly and prevents permanent damage.

When You Should Avoid It

• Warning sign: Your return includes many pages (e.g., over 10) that may jam a mail sorter or scanner if stapled. In such cases a paperclip or binding sleeve is safer.
• Warning sign: You are filing electronically and need to upload a PDF. Staples cannot be represented in a digital file, so paperclips (or no fastener) are the appropriate choice.

Pros and Cons

Pros

• Staples provide a quick, permanent closure that resists accidental separation during mailing.
• Paperclips are reusable, non‑destructive, and make it easy to add or remove pages later.

Cons

• Staples can tear pages when removed and may cause jams in automatic mail or document feeders.
• Paperclips can slip off, especially with thin or slick paper, risking pages becoming separated.

Decision Checklist

• How many pages are in the return, and will a staple fit without creating a bulk that could jam processing equipment?
• Am I mailing the return or submitting it electronically (scan or upload)?
• Do I need to add or remove documents after the initial assembly?

Alternatives to Consider

If neither stapling nor paperclipping feels ideal, you can use a folding tab, a thin binder clip, or a self‑sealing envelope that keeps pages together without fasteners. For electronic filings, convert the documents to a single PDF and avoid any physical fasteners altogether.

Final Recommendation

For short, single‑page mailed returns, a staple is efficient and reliable. For multi‑page returns, especially those that will be scanned or stored, a paperclip (or a non‑destructive binder) is the safer choice. Always verify the filing instructions of your tax authority and, if you’re unsure, consult a tax professional or the agency’s guidance.
