As a part of my retirement planning xls I also simulate what my federal tax liabilities are. I would love to hear what part of people's taxable income that comes from equities (be it stocks, mutual funds, or etfs) ends up being qualified dividends/long term capital gains. Right now I assume 70% of my taxable income that can be attributed to my equity holdings are qualified dividends/long term capital gains and the rest dividends from ETFs or Mutual funds.
