When you file your tax return, the U.S. Postal Service offers these tips: As defined in 39 CFR 310, first class mail includes handwritten and typed correspondence, invoices and bank statements, bank transfers (checks), postcards, and professional reply mail (BRM). First class mail is personal and cannot be opened for inspection by mail. First-class mail is for individual pieces weighing 13 ounces or less. It includes shipping service to a new address for up to 12 months or return service if the part is not delivered. Any envelope or parcel marked First Class Mail weighing more than 13 ounces will be treated as priority mail. Multiple shipments sent to the same address must be combined into one large envelope, as permitted by law. Each flat-rate box produced by USPS is charged at a flat rate, regardless of actual weight (up to 70 pounds) or domestic destination. This class of mail reduces postage costs by allowing the sender to enter bulk shipments of packages into the USPS delivery network.

Each shipment must contain at least 50 pieces. Height and weight restrictions are available in the DMM. SSC offers delivery of one to six days depending on distance. Packages may contain documents and records contained in a corrugated box or envelope of 9 x 12 or more. SSC`s ground services are guaranteed delivery dates that ensure tracking. For added security, you can purchase a shipping certificate at the post office. A shipping certificate is proof of receipt of the shipment that proves that you filed your tax return on a specific date. After sending your taxes, keep your receipt in a safe place.

Swiss Post® does not keep copies of receipts. If your return is delayed or lost, the postmark will not be available, but your shipping certificate will prove that you sent your return on time. Use the U.S. Postal Service® to file your tax return, get proof that you sent it, and track their arrival at the IRS. If the insert is not damaged by folds, all inserts must be folded to allow the use of a standard envelope. International First Class Mail meets IRM First Class Mail Criterion 1.22.2.2.1, First Class Mail. This is the most economical way to send letters and large envelopes using USPS. The CPS does not include new address transfer services. If a packet is undeliverable or rejected by the resident, an SPC attempts to find a new address through publicly available address services. If the attempt fails, the package is returned to the sender. Shipping and returns must be confirmed on each item. The IRS pays for the shipping and return of duly certified standard mail items using a weighted factor as indicated by the DMM.
