Matching Gifts Program
Many companies/corporations/foundations offer matching gift programs, whereby they will match your charitable gifts. You can inquire with your human resources office to find out if your company has a matching gift program. If so, simply fill out the form provided by your company and include it with your gift.
Some companies reward employees for volunteering their time by awarding grants to the nonprofit of choice. Your human resource office can tell you if these programs exist at your place of employment. What a great way to give both time and money to the theatre.
