The previous wait time was one year because of concerns about blood-borne pathogens, which can transmit diseases such as HIV and hepatitis, alliance spokeswoman Odette Struys said. The shorter wait time comes after regulation changes in Florida, where the alliance is based. ... As of January 2012, Florida was the last state among the three to require tattoo artists to have a license, which includes mandatory testing, hygiene standards and classes on how to prevent the spread of disease.

NewYork BloodCenter - if applied in NJ, no wait: If elsewhere, 12 months after application
 
American Red Cross  - Wait 12 months after a tattoo if the tattoo was applied in a state that does not regulate tattoo facilities. 

Acceptable if the tattoo was applied by a state-regulated entity using sterile needles and ink that is not reused. Cosmetic tattoos applied in a licensed establishment in a regulated state using sterile needles and ink that is not reused is acceptable. There are 40 states that currently regulate tattoo facilities. You should discuss your particular situation with the health historian at the time of donation.
