Brandy Maben argues that retirement planning should not revolve around a 401(k) alone. She recommends spreading assets across taxable, tax-deferred, and tax-free accounts to manage future tax risk, liquidity needs, inheritance rules, and the tax treatment of different investments and conversions.

In this Wealthion interview, host Maggie Lake speaks with Brandy Maben, identified as a director at Windrock Wealth Management, about portfolio construction and why it can be a mistake to overemphasize a 401(k). Brandy’s core message is that investors should think in terms of account diversification, not just asset diversification: taxable, deferred, and tax-free buckets each serve different purposes and can reduce future tax and liquidity problems. She argues that many clients accumulate too much wealth inside tax-deferred accounts because they are repeatedly told to “save, save, put it in your 401k defer the tax,” but that this can create a mismatch later in life. Her preferred rule of thumb for someone without professional guidance is to aim for roughly one-third in taxable, one-third in deferred, and one-third in tax-free accounts such as a Roth. …
Immediate setup: review whether retirement assets are too concentrated in deferred accounts and whether Roth or taxable buckets need to be built now. The near-term risk is being boxed into future RMDs and a high tax bill.
Over the next few months, the likely path is a gradual shift toward more balanced account structures, especially for investors still accumulating wealth. Confirmation comes from using conversions, Roth contributions, and taxable flexibility to reduce future tax concentration.
The structural thesis is that retirement outcomes will increasingly depend on tax regime navigation, account design, and inheritance rules, not just portfolio returns. Tax-free compounding and flexible asset placement remain durable advantages if policy and estate rules continue to evolve.
Investors should diversify across taxable, deferred, and tax-free account types rather than relying mainly on a 401(k).
This is the central thesis of the conversation and is stated repeatedly.
Overconcentration in a 401(k) can create future tax and required minimum distribution problems.
Brandy says large deferred balances can lead to high future marginal brackets and RMD issues.
If future tax rates rise, tax-free accounts like Roths become even more valuable.
The guest explicitly frames future tax uncertainty as a reason to build tax-free buckets.
Why is focusing too much on 401(k) retirement accounts a problem?
Clients often come in with 401ks that are exaggeratingly large relative to their overall wealth. The problem is that saving in only a tax-deferred bucket ignores the need for multiple account structures (taxable, deferred, tax-free) to manage tax implications efficiently in retirement, not just immediately.
What factors should we consider when structuring a retirement portfolio beyond the 60/40 debate?
The structure depends on your overall net worth and whether you expect to be in a higher tax bracket in retirement. If you'll be in a higher bracket, saving tax-free money (like Roth) is important. If you're at peak earnings now, deferring taxes may make sense. A general rule for those not working with a professional is to split savings into thirds: taxable, deferred, and tax-free (Roth).
What problems does the 'third, third, third' account diversification solve?
Brandy gives an example of a successful surgeon who saved heavily in his 401k and taxable account but faces required minimum distributions that will put him in a 40% marginal tax bracket. With taxes potentially increasing, he's afraid of paying 60-70% later. Opening a Roth and doing conversions means half that money won't be taxed later. Additionally, alternative investments like farmland (10-year maturity) or venture capital (16x returns) can be strategically placed in a Roth to avoid taxes when they mature.
