Washington D.C. has enacted sales tax exemptions for sales of feminine hygiene products and diapers. “Feminine hygiene products” mean sanitary napkins, sanitary towels, tampons, menstrual cups, or sanitary pads. A “diaper” is an absorbent incontinence product that is washable or disposable and worn by a person, regardless of age or sex, who cannot control bladder or bowel movements. The exemptions were approved on December 6, 2016 and will become effective after a 30-day congressional review period.(Act 21-557 (D.C.B. 21-696), Laws 2015, approved December 6, 2016, effective after a 30-day congressional review period)
