All you need to open a Fidelity Roth IRA is a name, address, Social Security number, employment information and a few minutes to type it all into Fidelity’s forms online or in its mobile app. After you create a username and password, you’ll be able to transfer money into your account via an electronic funds transfer (EFT), mobile check deposit or direct transfer. Deposits are generally available to purchase investments within four business days, according to Fidelity. Fidelity Roth IRAs have a $0 minimum account requirement, but the sooner you fund your account and choose investments (which start at as little as $1), the faster you can get your money working for your future.
