Portuguese tax law, allows you to donate 0.5% of the taxes the Government charges to a charitable institution. CAIS, an institution that helps homeless people, wanted to suggest taxpayers to donate their 0.5% to them. March, the month to fill the Annual Tax Declaration Form is the perfect time to tell Portuguese taxpayers they can take from the Government and give to those in need. Hence being like Robin Hood. So we posted “Robin Hood” like posters on city trees, secured by arrows, with all the information necessary to donate 0.5% to CAIS.
