How does Net Unrealized Appreciation (NUA) work for 401k invested in employer stock? Bank of America situation
My father is about to retire next month. Around 12 years ago, he moved his entire 401k into Bank of America stock, which is also his employer. His retirement advisor at BOA is now telling him something interesting about his options. According to the advisor, if Dad rolls his 401k into an IRA, he would typically pay regular income taxes on the Net Unrealized Appreciation (NUA). But the advisor mentioned a special situation - if he does the distribution right now, he could take advantage of what they called an IRS "life event" exception for NUA and would only have to pay long-term capital gains tax instead of regular income tax rates. I'm trying to understand if this is accurate information. Most of what I've researched makes it sound like NUA is mainly relevant when company stock is granted to employees, and those shares are part of a diversified 401k. In my dad's case, he had a diverse portfolio for about 18 years and then decided to put everything into Bank of America stock. Does anyone understand the NUA rules well enough to clarify what his options really are? Is there actually a tax advantage he can use during this retirement transition? I want to make sure he's getting accurate advice since this involves a substantial amount of his retirement savings.

The NUA strategy is real and can be incredibly valuable in your dad's situation! Here's what's happening in plain language: When your dad retires, he can take a lump-sum distribution of his entire 401k. The special NUA tax treatment lets him pay ordinary income tax ONLY on what he originally paid for the Bank of America stock (the cost basis). Then, he only pays the lower long-term capital gains rate on all the growth (the "appreciation") when he eventually sells the shares. This is different from rolling everything to an IRA, where he'd eventually pay ordinary income tax on ALL the money when withdrawn - which could be a much higher tax rate. The "life event" your dad's advisor mentioned refers to triggering events that allow this strategy: retirement, disability, separation from service, or reaching 59½. So retirement definitely qualifies! This strategy works because he invested in employer stock within the 401k. It doesn't matter that he changed his allocation to BOA stock later - what matters is that it's employer stock within the 401k at distribution time.

•Thanks for explaining! So to be clear, if he uses this NUA strategy, would he need to pay the tax on the cost basis immediately this year? And does he have to sell all the stock at once, or can he transfer it somewhere and sell portions over time while still getting the long-term capital gains treatment?

•He would need to pay ordinary income tax on the cost basis in the current tax year when he takes the distribution - that can't be delayed. He doesn't have to sell all the stock at once after the distribution. He can transfer the shares to a taxable brokerage account and then sell portions over time as needed. The NUA tax advantage stays with those shares, so whenever he decides to sell - whether next month or years from now - he'll only pay the long-term capital gains rate on the appreciation portion.

I went through something similar with my employer stock in a 401k. I highly recommend checking out https://taxr.ai - it really helped me understand the NUA strategy. I uploaded my 401k statements and it identified my cost basis and potential tax savings with different distribution strategies. The NUA rules are super confusing, and my regular tax advisor wasn't very familiar with them. The tool actually showed me that my cost basis was much lower than I thought, making the NUA strategy even more valuable. It also calculated the projected tax difference between rolling to an IRA vs. using the NUA provision.

•How accurate was it compared to what your company's 401k administrator provided? My HR department gave me cost basis info but it seems way off based on when I bought the company stock.

•Does it work for partial distributions too? My advisor told me I needed to take the entire 401k as a lump sum for NUA to apply, but I'd rather not distribute my non-company stock investments.

•It was surprisingly more accurate than what my 401k administrator initially provided. The tool flagged a discrepancy, which led me to request a detailed transaction history from my plan. Turns out there was an error in their reporting that would have cost me thousands in unnecessary taxes. For partial distributions, your advisor is correct. NUA treatment requires a lump-sum distribution of your entire 401k balance following a qualifying event like retirement. You can't just distribute the company stock portion while keeping other investments in the 401k. That's one of the tricky requirements that makes this planning complicated.

Just wanted to update after trying taxr.ai from the previous comment. Total game changer for my situation! I uploaded my 401k statements and it broke down exactly what would be taxed at ordinary income rates vs. capital gains rates with the NUA strategy. It showed my cost basis was only $42,000 while my company stock in the 401k is now worth about $180,000. Using NUA would mean paying ordinary income tax on just the $42K and then capital gains on the $138K appreciation when I sell. The tool calculated I'd save approximately $15,000 in taxes compared to a traditional IRA rollover! It also explained that I need to take the ENTIRE 401k distribution in one tax year (doesn't have to be a single transaction though) for the NUA treatment to apply, which confirmed what my advisor said. Super helpful since these rules are so specific.

For anyone dealing with the IRS on NUA issues or trying to get clarification from your 401k administrator, I highly recommend Claimyr (https://claimyr.com). I was stuck in IRS phone tree hell trying to get guidance on my own NUA situation for weeks. Their service got me connected to an actual IRS agent in about 15 minutes when I had been trying for days on my own. You can see how it works here: https://youtu.be/_kiP6q8DX5c The IRS agent was able to confirm that the NUA strategy was valid for my situation and explained exactly what forms I needed to file. My 401k administrator was giving me conflicting information, but getting that direct confirmation from the IRS gave me the confidence to proceed with the strategy.

•How does Claimyr actually work? Do they just call the IRS for you or do they have some special access? I'm confused about how they get through when regular people can't.

•Sounds too good to be true. The IRS doesn't take calls about tax strategies or give advice like that. They only answer procedural questions. I've worked with tax professionals for years and they don't even get special access to IRS agents.

•They don't call for you - they secure your place in the IRS phone queue and then call you when an agent is about to pick up. It's basically a system that navigates the IRS phone tree and waits on hold for you instead of you having to do it yourself. When an agent is about to answer, you get a call so you can speak directly with them. You're right that the IRS doesn't provide tax strategy advice. I should have been clearer - the agent helped confirm the procedural requirements for NUA treatment and verified the correct reporting forms. They didn't tell me whether I should use the strategy, just confirmed how it works procedurally. My tax professional still handled the actual strategy implementation.

I need to eat some crow here. After my skeptical comment above, I tried Claimyr for an unrelated tax notice issue that had been driving me crazy. Got through to an IRS agent in about 20 minutes after trying for weeks on my own. While they couldn't provide tax strategy advice as I mentioned (that's what CPAs and tax attorneys are for), they were incredibly helpful with the procedural aspects of my situation. For your dad's NUA situation, they could help clarify the forms needed and verify the distribution requirements. I still recommend working with a tax professional who specializes in retirement distributions for the actual strategy, but getting direct IRS clarification on the procedural elements really helped my confidence in the process. Definitely worth the service fee to save hours of frustration.

One important thing nobody's mentioned yet: your dad should consider diversification regardless of the tax strategy. Having an entire retirement portfolio in a single bank stock is extremely risky, especially as he enters retirement. Even if the NUA strategy works out tax-wise, he should consider selling some of that BOA stock after the distribution and diversifying into a more balanced portfolio. The potential tax savings from NUA might be less important than protecting his retirement from single-company risk.

•That's a really good point. I've been so focused on the tax angle that I forgot about the risk factor. Do you have any suggestions for how to balance the tax advantage of the NUA with the need to diversify? Should he sell and diversify all at once or gradually?

•I'd suggest a gradual approach to diversification after the NUA distribution. One strategy could be selling 10-15% of the position per year for the first few years of retirement, then reassessing. This accomplishes a few things: The immediate NUA tax benefit is preserved, but risk is systematically reduced over time. Spreading the sales across multiple tax years may help manage the impact of capital gains taxes and potentially keep him in lower tax brackets. It also prevents selling everything at a potential market low point. Remember that after the NUA distribution, he'll need to hold these shares in a regular brokerage account. This gives him freedom to implement a proper diversification strategy at his own pace while still benefiting from the favorable tax treatment.

Wait, do you have to take the entire 401k as a lump sum for NUA? I'm confused because my 401k has both company stock and mutual funds. Would I have to cash out everything to get the NUA benefit for just the company stock portion?

Luca Esposito
•Yes, the IRS rules require a complete distribution of your entire 401k balance within a single tax year (doesn't have to be a single transaction) to qualify for NUA treatment. That means all assets - both the company stock and the mutual funds. Here's what most people do: distribute the company stock in-kind to a brokerage account (for NUA treatment) and simultaneously roll over the mutual funds/other investments to an IRA (tax-free). The entire account is emptied, satisfying the lump-sum requirement, but only the company stock gets the special NUA tax treatment.

I work in retirement planning and see NUA situations regularly. Your father's advisor is correct about the tax advantage, but there are a few critical details to verify before proceeding: 1. **Timing matters**: The NUA distribution must happen in the same calendar year as his retirement. If he retires in May but waits until next year to distribute, he loses the opportunity. 2. **All-or-nothing rule**: As others mentioned, he must distribute his ENTIRE 401k balance. The good news is he can split the distribution - take the BOA stock in-kind to a brokerage account (for NUA treatment) and roll the rest to an IRA if there are other investments. 3. **Cost basis verification**: Make sure BOA's 401k administrator provides accurate cost basis information. I've seen cases where the reported basis was wrong, which can dramatically impact the tax calculation. 4. **Consider the concentration risk**: Having 100% in BOA stock is extremely risky for retirement. Even with the tax advantage, he should have a plan for gradual diversification after the distribution. The NUA strategy can save thousands in taxes, but it requires precise execution. I'd recommend getting a second opinion from a fee-only financial planner who specializes in retirement distributions to make sure all the details are handled correctly.

This is excellent advice from everyone here. I wanted to add one more consideration that's often overlooked with NUA strategies - state taxes. While the federal tax benefits are clear (ordinary income tax on cost basis, capital gains on appreciation), don't forget that your dad's state of residence will also tax the distribution. Some states have no capital gains tax or lower rates than ordinary income, which could add to the NUA benefit. Other states tax capital gains as ordinary income, which might reduce the overall advantage. Also, if your dad is considering relocating in retirement, the timing of the NUA distribution versus a potential move to a more tax-friendly state could be significant. For example, if he's planning to move from a high-tax state like California to a no-tax state like Florida, it might be worth coordinating the distribution timing with the move. I'd definitely echo the recommendation to work with a retirement planning specialist who can model out the complete tax picture - federal, state, and the long-term implications of the concentration risk in BOA stock. The NUA strategy is powerful when executed correctly, but the details really matter.
