Should I Staple Or Paperclip My Tax Return?

When It Makes Sense

• Good fit: You are mailing a single‑page personal tax return to a tax authority that expressly permits stapling, and you want a compact package.
• Good fit: You are submitting a small bundle (1‑2 pages) of supporting documents along with your return, and a staple keeps everything together without creating excessive bulk.

When You Should Avoid It

• Warning sign: The filing instructions specify no staples (e.g., for electronic scanning or bulk processing), as staples can jam machines.
• Warning sign: You have a multi‑page return with several schedules or attachments; staples may rip pages or make it difficult for the clerk to separate documents.

Pros and Cons

Pros

• Staples provide a permanent, tamper‑evident closure, helping ensure pages stay together during transport.
• Stapling creates a neat, compact packet that fits easily into envelopes and filing trays.

Cons

• Many tax agencies require paperclips or no fasteners because staples can damage scanners or shredders.
• Removing a staple without tearing paper can be difficult, especially for older, thicker forms.

Decision Checklist

• Does the tax authority’s filing instruction list a preference or prohibition for staples?
• How many pages are you sending, and will a staple hold them securely without risk of tearing?
• Will the documents need to be opened and re‑sorted by staff, and would a staple hinder that process?

Alternatives to Consider

Using a paperclip is a low‑risk alternative that keeps pages together yet allows easy removal. If you are filing electronically, simply upload PDFs without any physical fasteners. For larger bundles, a rubber band or a small folder can keep documents together without affecting scanning equipment.

Final Recommendation

If the filing guidelines permit staples and you have a short, single‑page return, stapling is acceptable. In most other cases—especially when instructions are silent or advise against staples—a paperclip or no fastener is safer. Always verify the specific requirements of the tax agency and, for high‑stakes filings, consider consulting a tax professional.
