Backdoor contribution limit

[michael]

Say you have contributed $18k to your 401k, then $5500 to your Roth IRA.  Supposedly you can contribute more to the Roth by doing a non-deductible traditional IRA contribution, then roll it over ("convert") to your Roth IRA.

Is there a limit on the amount you can contribute to the non-deductible traditional and then convert?  Can someone provide an IRS link for confirmation?

Nope, the limit across all IRAs is $5500, so if you've already contributed $5500 that's it. The backdoor roth is useful for people to make too much to be eligible for a direct roth contribution. They can still put in at most $5500 though.

There is something called a mega backdoor roth which is something else. It requires an employer plan set up in a very specific way (to allow both aftertax contributions and in service withdrawals or rollovers while still working).
