We were in Italy last month, (Meant to post this earlier but got sidetracked.). Before our trip, we had researched, read several articles and posts about not needing to tip in Italy. (We did see in our research that "rounding up" in taxis was normal but not really elsewhere.).
I know some will disagree with me but tipping is very welcome in Italy, especially in tourist activities following almost 1-1/2 years of no tourism due to Covid-19. We were so confused that we finally asked our hotel receptionist, whom we had befriended, what the policy was around tipping there. (BTW, I had offered her a tip for something she went above and beyond in helping me out of a severe jam and she refused to accept it but was appreciative for the offer.). She said this is a misconception. She said tipping is welcome though not required in Italy to whatever one feels right to do so. She did say it wasn't a generally acceptable amount (like in the USA with 18-20% at restaurants). She also warned to check restaurant bills before adding a tip to be sure there isn't a "service charge" listed, which is commonly in lieu of a tip. One of our tour guides we talked with said that after the long time with Covid and no tourism, these tips are extremely appreciated. (The Italian government only provided a nominal amount to help during Covid which equated to roughly 2 months pay for that tour guide.)
During our trip, we tipped our tour guides and at restaurants. All were so appreciative every time, much more appreciative than in the States. Several did not expect it but were sincerely thankful for the tip.
I write this hoping to help others like us that were so confused about whether to tip or not in Italy. Enjoy your time there; we did!
