I have some money in a regular TD Ameritrade brokerage account, as well as some in my TD Ameritrade Roth IRA. For 2016, should I move the money from the regular brokerage account into my TD Ameritrade Roth IRA? Or leave it in the regular brokerage account? The 2016 contribution limit is 5500 I believe, and just want to know if there's any tax advantages down the line to moving it over from regular brokerage to Roth. Will they tax the regular brokerage eventually when I withdraw it?
