Guinta has described the deficit and debt as "a spending problem, not a revenue problem." He has faulted both parties for their role in unsustainable spending, and advocates that spending be cut and made "more effective and efficient". Guinta supports providing tax incentives for small businesses, lowering taxes, and reducing government spending. He has signed the Taxpayer Protection Pledge, a pledge never to increase taxes or revenue. Guinta supports "broad-based" tax reforms that "lower taxes for all Americans", and simplifications to ensure that average Americans can fill out their own tax forms. He supports reforms to automatic spending programs. Guinta has opposed the automatic cuts required by the Budget Control Act of 2011 (the "sequester") that affect defense spending, out of concern for employment at the Portsmouth Naval Shipyard.
