Partnerships

IRS and organizations all over the country are partnering to assist taxpayers. Through these partnerships, organizations are also achieving their own goals. These mutually beneficial partnerships are strengthening outreach efforts and bringing education and assistance to millions.

For more information about the programs for individuals and families and how your organization can be a part of this partnership read more at Become an IRS Partner. Organizations interested in operating a free tax preparation site through the Volunteer Income Tax Assistance or Tax Counseling for the Elderly programs may consider applying for a VITA or TCE Grant. Anyone interested in volunteering to prepare free tax returns can read how to become an IRS Tax Volunteer, or if you need to find a volunteer site to have your tax return prepared absolutely free, go to Free Tax Return Preparation for you by volunteers.
