Investors & landlords

I don't have the original question in my string, but this is a ratio I used for NIIT and State Income Taxes:

 

(Interest+Ordinary Dividends+Capital Gains) / AGI x State Tax on W-2 & Paid on prior years taxes. This result is limited to $10,000. If you have a Sales and Use tax like WI does, be sure to adjust your tax paid by that amount.
