For high earners

Supersize your tax-free savings.

If your 401(k) plan allows it, the mega backdoor lets you move a large amount of extra money into a Roth each year, far beyond the normal limits.

Watch the quick version

See how it works through one simple example.

Is this you?

Your 401(k) plan allows after-tax contributions plus Roth conversion.
Not every plan supports this. The first step is checking yours.

Here is the idea, in plain words

You make extra after-tax contributions to your 401(k), then move them into a Roth.

This can be tens of thousands a year of tax-free growth, on top of normal contributions.

The only catch is that your specific plan has to allow it.

What to watch out for

The honest version.

  • Only works if your plan allows after-tax contributions and conversions.
  • Convert promptly so the growth on after-tax money is not taxed.
  • Coordinate with your overall 401(k) limits.

Common questions

How do I know if my plan allows it?

Ask HR or your plan provider about after-tax contributions and in-plan Roth conversions.

How much can I move?

Often tens of thousands a year, depending on your plan and other contributions.

Is it worth the effort?

For high savers, the tax-free growth can be very large.
