Tax Deadline is Extended to April 18 – Mailing Tips

For you tax payer procrastinators out there, hopefully you are aware that this year tax day is April 18th.  The date was pushed back three days, because of Emancipation Day, a holiday in Washington, DC.  The United States Postal Service has these tips to offer up a smoother (and hopefully less stressful) process of meeting the mailing deadline.

Tax Day Mailing Tips

  • Taxpayers are urged to avoid the typical errors made when mailing their returns each year, which are: unsigned forms, not enough postage and depositing returns in collection boxes whose pickup time is past.
  • Use pre-addressed labels where possible. Write clearly. Take special care to ensure that handwritten envelopes are legible.  Include a return address.
  • Use First-Class postage –The Internal Revenue Service recognizes the First-Class letter postmark as proof a return was mailed on time.
  • Affix sufficient postage. One ounce is 44 cents; 20 cents for each additional ounce–2 oz. 64 cents; 3 oz 84 cents.
  • Double-check postage. Weigh any return that feels heavier than one ounce.
  • Rule of thumb: up to 5 sheets of 20-lb. paper in a #10 envelope equals one ounce.
  • The IRS does not accept postage due mail even if it has the April 18 postmark; tax returns bearing insufficient postage will be returned—meaning taxpayers will be penalized for filing late tax returns.
  • For customers who send original receipts to tax agencies, registered mail is a good choice.
  • Make certain bulky envelopes are securely sealed.
  • Postal regulations require that stamped tax returns weighing 13 oz. or more must be mailed at a post office.  They cannot be mailed in a collection box. 
  • Automated Postal Centers (APC), or self-service kiosks, are available 24/7 at various Post Offices (locations at Postal Locator on, and an April 18 date stamp/postmark will be provided if the mail is deposited by the last pickup time posted on the Automated Postal Center on April 18.  Certified/Return Receipt service is available.   

Good luck and I’ll be the one standing behind you in line .
