Certified Mail® software for accounting firms

Once upon a time, filing income taxes and sales taxes for your clients meant you had to rely on the U.S. Postal Service to deliver your mail on or before the due date to comply with regulations regarding on-time filing. Changes in tax code and technology have made compliance much easier for accounting firms. Current United States tax code (26 U.S.C. 7502) allows you to substitute proof of “timely mailing” for “timely filing and paying,” taking all the stress out of knowing whether or not your clients’ matter made it to the IRS in time. 

Many accounting firms throughout the nation, including two of the “Big Four,” have turned to Simple Certified® , online software that provides them with a Proof of Acceptance (Electronic), a PDF form that provides the City, State, Time and Date the USPS acknowledges possession of the item. The Proof of Acceptance (Electronic) has been held as the legal equivalent of the PS 3800 Certified Mail Receipt or PS3877 Firm Book, with a Red Date stamp. A Proof of Delivery (Electronic) is also automatically posted to the accounting firm’s online account, and for firms that also want the signature of the recipient, the USPS Return Receipt (Electronic), the legal equivalent to the PS3811 Green Card is posted to firm’s account. All these digital records are saved to the online account for 10 years and can be downloaded anytime.

In addition to providing on-time filing for your clients, Certified Mail software for accounting firms offers the following benefits.

Simplification of the Mailing Process

With Certified Mail® software, you can eliminate many of the steps you need to mail your clients’ matter to the IRS.

Instead, you can sign into the platform and print a USPS-approved cover sheet or label from your home or office printer in seconds.

Increased Speed and Accuracy

If you choose to use Certified Mail® software, the days of waiting for return Green Cards from the USPS are over. Once the item is delivered, the platform posts a .pdf version of the USPS Return Receipt (Electronic) to your account and sends an email to you and others you designate within 24 hours of delivery. Not only is this faster, but the accuracy of Certified Mail® software has prompted the IRS, state and federal courts, and other government entities to accept the USPS Return Receipt (Electronic) as a Green Card equivalent.
