If you are approaching retirement and hold highly appreciated company stock in your employer’s 401(k), you may have a unique tax-planning opportunity.
Known as net unrealized appreciation, or NUA, this strategy can potentially allow some of the growth in your company stock to be taxed at long-term capital gains rates rather than ordinary income tax rates.
The rules are specific, so understanding the opportunity before rolling your 401(k) into an IRA can be important.
What Is Net Unrealized Appreciation?
Net unrealized appreciation is simply the growth in your employer stock while it has been held inside your retirement plan.
For example, suppose your 401(k) purchased company stock for $10,000 and those shares are now worth $50,000.
- Original cost: $10,000
- Current value: $50,000
- Net unrealized appreciation: $40,000
Normally, distributions from a traditional 401(k) are taxed as ordinary income. NUA provides a special tax treatment for qualifying employer stock that can change how that $40,000 of appreciation is eventually taxed.
How Is NUA Taxed?
This is where the strategy can become valuable.
If the requirements are met, the employer stock can be transferred from the 401(k) directly into a taxable brokerage account rather than rolled into an IRA.
Using our previous example:
- The $10,000 original cost of the shares is generally taxed as ordinary income when the stock leaves the 401(k).
- The $40,000 of NUA is not taxed at that time.
- When the shares are eventually sold, that $40,000 of appreciation is generally taxed at long-term capital gains rates.
Any additional appreciation occurring after the shares leave the retirement plan follows the normal capital gain holding-period rules.
Why does that matter? Federal long-term capital gains rates may be significantly lower than the ordinary income tax rate that could otherwise apply to distributions from a traditional retirement account.
For highly appreciated company stock, that difference can potentially create significant tax savings.
What Happens if I Roll the Stock Into an IRA Instead?
This is an important distinction.
If you simply roll the company stock from your 401(k) into a traditional IRA, the rollover itself is generally tax-free. However, you typically give up the opportunity to use NUA treatment on that stock.
Future withdrawals from the traditional IRA would generally be taxed as ordinary income, including amounts attributable to the stock’s previous appreciation.
That is why company stock should be reviewed **before completing a 401(k) rollover**. Once the stock has been rolled into an IRA, the NUA opportunity generally cannot be recreated.
Who May Benefit From an NUA Strategy?
NUA is not automatically the best choice simply because you own company stock.
The strategy may be particularly worth evaluating when:
- Your 401(k) holds employer stock that has appreciated significantly.
- The stock has a relatively low cost basis compared with its current value.
- You expect the long-term capital gains rate on the appreciation to be lower than your ordinary income tax rate.
- You are approaching retirement or have recently left your employer.
- You have sufficient cash flow to handle the income tax created by distributing the stock’s cost basis.
- The larger the appreciation compared with the original cost, the more valuable the potential tax-rate difference may become.
What Rules Apply to NUA?
NUA receives favorable tax treatment only when specific requirements are satisfied.
Generally, a qualifying distribution must follow a triggering event, such as:
- Reaching age 59½
- Leaving your employer
- Death
- Certain cases of disability
The employer stock must generally be distributed in-kind to a taxable brokerage account, and the retirement plan balance must be fully distributed within the same tax year. Other investments in the plan can often be rolled into an IRA while the company stock is transferred to the taxable account.
Because these requirements can be unforgiving, the transaction should be planned before distributions or rollovers are initiated.
Conclusion: Review Company Stock Before Rolling Over Your 401(k)
For many retirees, rolling an old 401(k) into an IRA may seem like a routine decision. But if that account contains highly appreciated employer stock, taking that step without evaluating NUA could mean permanently giving up a valuable tax-planning opportunity.
NUA will not make sense for everyone. The value depends on your stock’s cost basis, current value, tax bracket, retirement income, and long-term plans for the shares.
But when the circumstances are right, thoughtfully coordinating your retirement plan distribution can help reduce future taxes and protect more of the wealth you spent your career building.
