The ATASS Foundation (registered charity number 1131659) is a charitable trust founded and run by ATASS employees. It is funded by Give as You Earn and lump sum contributions from employees, who are then offered the opportunity to become trustees.

The trustees then meet for regular meetings and propose charities who are considered for a donation from the pool of funds. The Foundation aims to support a selection of local, national and international charities, working for a wide variety of causes.
