Farmers have benefited from unique tax treatment since the beginning of the income tax law. This paper explores agricultural influences on the passage of the income tax in 1913, using both qualitative and quantitative analysis. The results show that agricultural interests were influential in the development and passage of tax/tariff laws. The percentage of congressmen with agricultural ties explains the strong affection for agriculture. Discussion in congressional debates and in agricultural journals was passionate and patriotic in support of equity for farmers. The quantitative analysis reveals that the percentage farm population was a significant predictor of passage of the 16th Amendment by the states and of adoption of state income taxes in the 20th century.
