Mathieu Soete, 38, Amy Rugg-Easey, 33, and Alexandra Wilson, 32, will each be charged with a single count of criminal damage, and will appear in court on March 21, the Crown Prosecution Service (CPS) said.
The protesters draped huge sheets of black fabric over Sunak's residence in Yorkshire, northern England, while he was out of the country.
Greenpeace said the protest was peaceful and they would dispute the charges.
"The protest took place at one of Sunak's several houses, and great care was taken to make sure it was staged while the family were holidaying in California," the campaign group said in a statement.
