Key takeaways

  • The S. Mark Taper Foundation funds arts, civic affairs, education, environment, health and social services work, and supports general operating, programme and capital costs.
  • It prioritises organisations based in and serving Los Angeles County, but its geographic focus also covers Imperial, Riverside, San Bernardino and Ventura counties, so check your location fits before applying.
  • Most grants to organisations fall between $25,000 and $200,000, with a median of $75,000, so a request in that range is realistic; the Foundation also encourages applicants to ask for an amount proportionate to their own past grants, fundraising and budget.
  • Apply by Letter of Inquiry through its online portal within the fixed window of December through February each year, and note that it says it gives equal consideration to past grantees and organisations that have never received a grant from it.
  • Do not apply if you are a government agency, a public or private university or community college, an elementary, middle or high school, a charter school, focused on scientific or medical research or a specific disease, involved in elections or political campaigns or in documentary filmmaking or television programming, have had or will have a change in CEO or Executive Director within twelve months of LOI submission, have loans to or from board members or executive staff, have received a grant from the Foundation within the past three calendar years, or are seeking funding for an endowment, a vehicle, or an individual.
