Unfortunately, my wife and I have to try to decrease our investment income in taxable accounts for 2017 to qualify for a health insurance premium tax credit. Currently, we are very close to the $64,000 upper limit. I know some standard ways to do this - use index funds, low turnover mutual funds, tax managed funds, etc. Are there other good investment options that would produce non-taxable gains? I can get a pretty good estimate for dividends but unknown capital gain distributions are a killer. If I go over the income limit by $1, I will lose an $18,000 tax credit (subsidy).
