Former President Donald Trump has proposed implementing a federal gasoline tax holiday, which would suspend the current 18.4 cents per gallon federal tax on gasoline. The proposal aims to provide immediate relief to drivers facing high fuel costs.

However, transportation policy experts have raised concerns about the fiscal implications of such a move. The federal gas tax revenue is directed to the Highway Trust Fund, which finances road construction and maintenance projects across the country. This fund is already experiencing financial strain, and suspending the tax would further reduce its resources.

Separately, Amazon founder Jeff Bezos has proposed eliminating federal income taxes for the bottom half of American earners. The billionaire's suggestion has generated significant discussion about tax policy and income inequality, though specific details about implementation and funding mechanisms have not been provided.

Both proposals represent significant departures from current federal tax policy and would require congressional approval to implement. The gas tax has not been raised since 1993, and the Highway Trust Fund has required periodic transfers from general revenues to remain solvent. Any changes to either the gas tax or income tax structure would need to address questions about alternative funding sources for affected government programs.
