It is considered appropriate to tip approximately 20 percent to a tattoo artist, even more if he is creating a unique design. If creating the tattoo takes more than one session, it is good etiquette to tip after each session.
Tattoo artists are not paid an hourly wage. According to New Covenant Ink, their earnings are like those of hairdressers or manicure professionals, who rely in part on tips to make a living. In general, a 10 percent tip is considered very low, while a tip in the range from 15 to 25 percent is a good tip. Tipping a tattoo artist is important because of the intimate nature of the relationship between the tattoo artist and his client.
