Payroll giving, also known as Give As You Earn is an easy, flexible and tax-efficient way to make a regular donation to us from your salary. Because the donations come out of your gross pay (before tax), it costs you at least 25% less to donate. The income tax applicable to the donation is paid to PetSavers instead of HMRC, so a £5 donation costs a basic rate taxpayer only £4 and a higher rate taxpayer only £3!
