To help ensure a successful tax season for our customers we offer the following tax mailing tips:

• The Postal Service reminds customers to plan ahead and mail early. If you wait until April 15 to mail your tax returns, be sure to check the collection time posted on mail drops to verify your envelopes will be collected and postmarked on time.
• Ensure proper postage is affixed on your tax returns. The first ounce (about three sheets of paper) on a letter-sized envelope is 49 cents. The first ounce on a larger flat-sized envelope (bigger than 6 1/8 inches x 11 1/2 inches) is 98 cents. Additional ounces are 21 cents each for both size mail pieces.
• Make sure your tax return envelope has the proper IRS or FTB address and ZIP Code.
• Place your return address in the upper left corner of the envelope.
• Customers wanting proof their tax forms are mailed and received should use Certified Mail /Return Receipt service, which is available at your local Post Office during regular business hours.
