Can you explain to me how to get cash into a backdoor roth?

### REPLY:
I haven't done it yet, but I think you create a new normal IRA at your Roth's broker. Add money to the IRA, then convert it to the existing Roth.  There is a particular form you need to fill out that states you already paid tax on the IRA deposit, so that you are not taxed twice. Do it once a year.
