No taxation on augmentation.

That was the message yesterday at a Times Square protest against a proposed federal tax on cosmetic surgery.

Waving signs that read “Stop the Bo-Tax” and “Leave Our Bodies Alone,” demonstrators called the proposed 5 percent tariff on tummy tucks and boob jobs an unfair tax on working women.

“Patients save their money in order to have a procedure to help themselves look and feel better,” said Stephen Greenberg, a Manhattan cosmetic surgeon.

“The misconception about people having cosmetic-surgery procedures is that they’re wealthy. But it’s . . . the average person who wants to feel better about themselves.”

Irma Cadiz, 33, a Bronx waitress, said she was considering getting a tummy tuck, but the tax might put the procedure out of her budget.

“I want to get the tummy tuck, but it would cost somewhere between $6,000 and $10,000,” Cadiz said “Adding the tax would make it even worse.”

Melissa Guzman, 20, a model and actress from Staten Island, said “If you want to do something to your body, you shouldn’t be taxed on it.”
