I have an old Roth IRA held at TDAmeritrade valued around $6800. I'd like to transfer it into my existing Vanguard Roth IRA, but TDAmeritrade has a $75 "Outbound full account transfer" fee. There isn't a fee for a partial transfer. Is there anything keeping me from doing a partial transfer leaving $0.01 in the TDAmeritrade account? I have the Vanguard transfer form all filled out to do this, but it just seems too easy to avoid the $75 fee. Anyone done this?
If I do this, is there some documentation I need to save if/when I need to remove my contributions before turning 59.5?
