⏰ Don’t wait until the last day to mail your return
Because of changes to how USPS handles postmarks, dropping your return in the mail close to the deadline could result in a later postmark date.
To help ensure timely filing:
📬 Mail your return several days early
🏤 If mailing close to the deadline, take it to a post office counter
📄 Keep your receipt
File early to avoid late filing penalties and fees.
