Payroll Giving Celebrate pay day with Brainwave by signing up to your company's payroll giving scheme. Payroll giving is a hassle free, tax efficient way to support Brainwave. Your donation is calculated after your National Insurance contribution, but before Income Tax is deducted; this means part of your donation comes from money that would otherwise have been taken by HMRC. Ask your HR or Payroll Manager whether your company has a payroll giving scheme you can join. If they haven't, there are numerous agencies who would happily work with your employer (or you, if you are self-employed) to sent up a payroll giving Give as You Earn scheme, including: The Charities Aid Foundation Charities Trust Smart Giving Charitable Giving For the full list of government-approved agencies for Payroll Giving, click here to visit the HMRC website.
