Seven post offices in Maui County will accept federal income tax forms until midnight Tuesday - the day taxes are due - and postmark them for Tuesday.
The post offices will be closing at regular times but will have blue collection boxes, labeled with bright orange signs "Tax Mail Drop - Final Pick-Up Midnight." Tax forms with correct postage in those boxes by midnight will receive a Tuesday postmark, the U.S. Postal Service said.
Collection boxes and post office lobby drops at all other post offices will be collected at their regular posted times Tuesday.
The locations with late drop-offs in the county are:
* Maui - Kahului, Kihei, Lahaina (main), Makawao and Wailuku post offices.
* Molokai - Kaunakakai Post Office.
* Lanai - Lanai City Post Office.
Due to the declining numbers of taxpayers who submit hard-copy returns by mail, the Postal Service no longer provides curbside service to last-second filers.
According to the Internal Revenue Service, as of March 28, 91 percent of tax returns nationwide have been filed online. Of the 148 million returns expected to be filed this year, only 23 million will be paper returns, down 7 percent from last year, the IRS said.
The Postal Service offered some general mailing tips:
* Mail early in the day. Post offices typically become congested during lunchtime and in the late afternoon and evening on the Tax Day deadline.
* Ensure proper postage. First-class postage for a 1-ounce letter is 49 cents. Large envelopes and items weighing more than 1 ounce or larger than -inch thick require additional postage; check with a postal clerk to determine correct postage or check the Postal Service website at www.usps.gov for a postage rate calculator. Tax agencies do not accept postage-due mail; tax returns bearing insufficient postage will be returned - meaning taxpayers may be penalized for filing late returns.
* Proof of mailing/delivery. Mailers seeking proof of mailing and delivery should request "Certified Mail with Return Receipt" when mailing returns.
* Ensure proper addressing. Use preaddressed labels where possible. Write clearly and make sure bulky envelopes are sealed securely.
* Heavy packages require personal drop off. Mail with postage paid by postage stamps (as opposed to postage meter strips) that weighs more than 12 ounces must be presented in person to a clerk at a post office.
* Tax forms are not available at post offices.
