Protecting Life and Taxpayers Act of 2021 This bill requires federally funded entities to certify that they will not perform an abortion, and will not provide funds to any other entity that performs an abortion, except in cases of rape or incest or where a physical condition endangers the woman's life unless an abortion is performed. The bill's requirements do not apply to hospitals, as long as the hospital does not provide funds to any non-hospital entity for abortions that are not otherwise excepted.
