PORTLAND — Justin Daye got in line with his W2 in hand and hopes for a tax refund.

“It’s my first time doing it – filing taxes,” said Daye, a 19-year-old city resident who makes his living pouring and stamping concrete.

He was among the half-dozen or so people looking for help from the AARP’s taxpayer-assistance program during the lunch hour this tax day. Volunteers with the program will be available until 6 p.m. in the lobby of the post office on Forest Avenue.

Ryan Rush, a 50-year-old cook from Westbrook, was glad for the help.

“I have no idea,” he said. “I try, I mess it up.”

Tax day no longer means a mad rush at the post office because so many people now file electronically, said David Guiney, the postmaster in Portland.

“It used to be a crazy-crazy day for us, but it’s slowly diminishing,” he said.

Even so, the post office is trying to lower the stress level by having a lobby director assess the needs of customers in line.

The post office on Forest Avenue will be open latest in Greater Portland. The windows will be open until 9 p.m. Mail dropped in the boxes by midnight will be postmarked on time for tax purposes.
