What the result means

This result estimates how much dividend income may remain after state-level dividend tax. It also shows the dividend retention rate so you can compare gross and after-tax income.

State Dividend Tax = max(Annual Dividends - Adjustments, 0) × State Dividend Tax Rate - State Credits

State treatment of dividends varies. This tool uses only the values entered and does not apply official state-specific rules.

Example calculation

If annual dividends are $12,000, adjustments are $1,000, credits are $200, and the state dividend rate is 5%, estimated tax is $350 and after-tax dividends are $11,650.

Tips for better results

  • Separate qualified and non-qualified dividend assumptions if your jurisdiction treats them differently.
  • Track dividend adjustments and credits before entering final values.
  • Compare this result with federal dividend tax for a fuller after-tax picture.
  • State and local tax rules vary by jurisdiction, so verify assumptions before relying on the estimate.
