This year those age 70 and older may want to consider making a meaningful, tax-efficient gift to Sonoma Ecology Center using funds from their traditional or Roth IRA. With this way of giving you can:

  • Make tax-free gifts each year from your IRA withdrawals by having a portion transferred directly to SEC (up to $100,000 per year for an individual; $200,000 per couple with separate IRAs).
  • Use your Required Minimum Distribution for you gift to avoid taxes on the transfer of funds.
  • Avoid increasing your adjusted gross income and potentially subjecting your Social Security income to a higher level of taxation by giving directly from your IRA.
  • Provide a generous gift to SEC.

Please contact tiffany@sonomaecologycenter.org if we can provide more information to you or your advisors.


Each stock gift we handle strengthens our programmatic work while providing tax benefits for supporters.
