Backdoor Roth IRA is very easy. I do it every year. You make a contribution (non-deductible) to your traditional IRA. Wait a few days.
Then, most of the major financial companies (Vanguard, Fidelity, etc) have an option on the website where you can "Convert to Roth IRA". Select that and you're all set.
The one caveat, is that you should not do this if you have a sizable balance in ANY traditional IRA account. If you do, then you'll be hit with pro rata taxation on the conversion.
The only way to avoid that, is to roll all of your tIRA funds in to a 401K. So bottom line, if you carry no balance in your traditional IRA accounts (all of them, regardless of institution) you can just do the conversion no problem. If you do, then you need to make sure that money is rolled in to a 401K so that your traditional IRAs are empty.
