Headline: 📮 New 2026 USPS "Mailbox Rule": Is Your Tax Return Actually Late?

Attention!

For decades, we’ve relied on the "timely mailed, timely filed" rule. If you dropped your tax return in a blue mailbox on April 15th, the IRS considered it on time.

That has officially changed for the 2026 tax season.

As of December 24, 2025, a new USPS regulation (Section 608.11) clarifies that a postmark is no longer applied when you drop off your mail. Instead, it’s applied when your mail is first processed at a regional distribution facility.

What this means for you:

  • The Postmark Lag: If you drop your return in a collection box on the deadline, it might not reach a processing center until the next day—resulting in a late postmark and potential IRS penalties.

  • The "Rural" Risk: If you are mailing from outside a major hub (like areas around Austin), the lag can be 48 hours or more.

3 Ways to Protect Your Filing:

  1. Manual Postmarking: Take your envelope to the counter and ask the clerk to "Hand Cancel" or manually postmark it. This is free and provides the only guaranteed same-day date.

  2. Certified Mail: Use Certified or Registered mail. The receipt you get at the counter is your "Get Out of Jail Free" card if the IRS questions your filing date.

  3. E-File Early: The safest way to bypass the USPS "processing gap" is to file electronically through our secure portal.

Don't let a mailing delay turn into a tax penalty. If you're planning to mail a paper return or a large check this year, aim to send it at least 3 business days before the deadline!

For more information of this development check out this link.      This will trigger the flood of national Offer-in-Compromise mills to put out their “settle your tax debt for pennies on the dollar” and “The IRS writes off millions of tax debt each year”. Both true statements but read the fine print. You must qualify. Ahh, and therein lies the rub. How do I qualify and keep my country club membership, my Tesla lease and shopping at Whole Foods?

Unlocking the Secrets of an Offer in Compromise: A Comprehensive Guide Chapter 3 - How Much Do I Offer?

  Calculating the Amount of your Offer in Compromise – What is Your Reasonable Collection Potential (RCP)? Drum roll please! This is what you’ve been searching for – how much do I offer? How little can I get away with? Why not low ball them?   Here are the two most important concepts to understand before you start your OIC.   Key Point 1 - You’re not buying a car or a house. The Settlement Agent does not work on commission. They don’t have to settle and the decision to settle rests entirely with the Settlement Officer.

Reasonable Collection Potential (RCP) is a key factor considered by the IRS when evaluating an Offer in Compromise (OIC).
