Not One Penny (NOP) is a left-of-center tax advocacy group created to oppose the Tax Cuts and Jobs Act of 2017 (popularly known as the 2017 Tax Reform), a tax package passed by Congressional Republicans and signed into law by President Donald Trump in November 2017. NOP has previously called the Act as a “GOP tax scam” and the “Trump Tax.” ¹

NOP is project of the Sixteen Thirty Fund, which often operates alongside its charitable “sister” nonprofit New Venture Fund. Both groups are managed by philanthropic consulting firm Arabella Advisors. ² NOP is also affiliated with Tax March, another project of the Sixteen Thirty Fund.³
