The top 1% of earners typically pay much more in taxes than many other Americans. Nationwide, this group contributes 45% of total personal income taxes collected. However, the top 1% doesn't pay the same amount everywhere. Therefore, some states may be more dependent on this group than others for tax revenue.

With this in mind, SmartAsset examined the most recent IRS tax return data to determine exactly how much the top 1% of earners in each state pays in taxes, both nominally and relative to the rest of taxpayers.

Key Findings

• The top 1% of earners contribute over 60% of the income taxes collected from Wyoming residents. Wyoming's top 1% paid $3.16 billion in taxes compared to a total of $5.12 billion paid by all Wyoming residents. This was the highest relative contribution by the top 1% in any state. For comparison, Alaska's 1% contributed the lowest relative share of income taxes at 29.8%.
• Connecticut's top 1% pays the highest effective tax rate. The top 1% in Connecticut pay 27.69% on each dollar of income, while the average Connecticut taxpayer pays a rate of 17.7%. Meanwhile, the top 1% of earners in Arkansas saw the lowest effective tax rate for that cohort at 21.41%. 
• The top 1% earns more than 33% of income in four states. In Wyoming, the top 1% brings in 40.6% of all adjusted gross income (AGI), which adds up to $13.25 billion. The top 1% in Nevada (34.3%), Florida (34%) and New York (33.5%) also have particularly outsized earnings when compared with the local 99%.
• Nationwide, the top 1% of earners pay a 25.95% effective tax rate. This yielded a total of $993.7 billion dollars in income taxes paid by the top 1% over one year, or 45% of all individual income tax collected. The total adjusted gross income for this group over the same time was $3.8 billion.
