Kimberly Green | 2026-03-11
Tax season has officially begun, and many people are now facing an overwhelming array of tax brackets, deductions, and deadlines. The experience of filing taxes is a common one, however, the level of anxiety associated with that process is not experienced by all Americans to the same degree. Sam's List developed the Tax Confusion Index as a way to identify which areas of the United States have the greatest amount of confusion among taxpayers. In order to develop this index, we analyzed the number of Google searches for the commonly asked tax-related questions across all 50 states and Washington D.C. Key Findings Arkansas has the highest percentage of confusion with regards to taxes among all states, ranking first overall in search index scores across ten key search terms at a 72.2 (out of 100).

Southern states struggle most, while the Northeast leads in literacy. Regional data shows that the South is the most confused part of the country, while the Northeast is the most tax-literate.

In fact, Arkansan's search terms for "how to file taxes" are almost double that of many Northeastern States. West Virginia follows Arkansas, scoring 71.8, with the confusion of whether or not you qualify for a credit/return. The DC & Oklahoma both have an identical Index Score of 70.8. The confusion within the DC is centered on legislative changes such as the new tax brackets and standard deductions, in effect in 2026. While Oklahoma is heavily weighted towards the end of the filing process, Oklahomans lead the nation in search terms for "where...
