Matching Gifts Maximize Support

Many employers participate in generous charitable gift programs. Have you considered an employer-sponsored matching gift? You may not be aware of the fact that many companies offer this option, where your employer may make an equivalent donation to a cause you contribute to – in essence, doubling your gift. Imagine! For example, your $250 contribution could become $500 credited to you.

Criteria for matching gift contributions vary. Here are a few ways to find out whether your company participates in a matching gift program:

  • Make an inquiry with your company’s Human Resources division.
  • Simply google – Company Name Matching Gifts – to see whether a form is provided. If it is, please fill it out and send it to us (or finish it online and your employer will forward it to us automatically).

Some companies require an Employer Identification Number (EIN) to process a matching gift. The Mars Society EIN # is: 31-1585646. If your company offers a matching gift, the Mars Society will receive it after you have made your donation, so please keep your Mars Society contribution acknowledgement for your records.

For information about including the Mars Society in your estate planning, please contact Mars Society Development Director Michael Stoltz at: mstoltz@marssociety.org.
