Quick Answer
NUA allows you to pay ordinary income tax only on the original cost basis of company stock in your 401(k), while gains are taxed at capital gains rates when sold. For stock worth $200,000 with a $50,000 basis, you'd pay ordinary tax on $50,000 and capital gains on $150,000 - potentially saving $30,000+ in taxes.

How the NUA strategy works
Net Unrealized Appreciation (NUA) is a tax strategy that allows you to withdraw company stock from your 401(k) and pay ordinary income tax only on the original purchase price (cost basis), not the current market value. The appreciation gets favorable capital gains treatment.
According to IRS Publication 575, this strategy applies only to employer securities and requires a "lump sum distribution" - meaning you must empty your entire 401(k) plan within one tax year.
Example: $500,000 in company stock savings
Consider an executive leaving their company with these 401(k) holdings:
Without NUA strategy (traditional rollover):
With NUA strategy:
Qualifying requirements for NUA
Advanced timing considerations
The strategy becomes more valuable when:
What you should do
1. Request cost basis information from your plan administrator
2. Calculate potential tax savings comparing NUA vs. traditional rollover
3. Consider your state tax situation - some states don't tax capital gains
4. Plan the distribution timing within a single tax year
5. Consult a tax professional - mistakes can't be undone

Key takeaway: NUA can save high earners $50,000+ in taxes on large company stock positions, but requires precise execution and only works when leaving your employer with a lump sum distribution.

NUA considerations for retirees
As you approach retirement, NUA becomes particularly attractive because you likely have decades of company stock appreciation and may be in your highest tax bracket.
Retirement timing strategy
Many retirees benefit from splitting their strategy:
1. Year 1: Take the NUA distribution, paying ordinary income tax on cost basis
2. Year 2+: Sell stock gradually to manage capital gains and stay in lower tax brackets
3. Consider Roth conversions of other retirement assets during low-income years
Example: Phased retirement approach
A 62-year-old with $600,000 in company stock (basis: $150,000):
Medicare and Social Security considerations
Large NUA distributions can:
Plan the distribution for a year when other income is lower, such as the gap between retirement and Social Security claiming.
Estate planning benefits
Company stock distributed via NUA gets a "stepped-up basis" for heirs, potentially eliminating capital gains taxes entirely if held until death.
Key takeaway: Retirees can maximize NUA benefits by timing the distribution during low-income years and selling stock gradually to minimize capital gains rates and avoid Medicare surcharges.

NUA with multiple employer plans
People with multiple jobs face unique NUA challenges since the strategy requires a complete distribution from the specific plan containing company stock.
Multi-plan coordination
If you have company stock in your current employer's plan plus old 401(k)s elsewhere:
Example: Strategic plan management
An employee changing jobs has:
Optimal strategy:
1. Use NUA for current company stock ($200,000)
2. Roll other current company investments ($200,000) to IRA
3. Keep previous employer 401(k) separate or roll to same IRA
4. Maintain clear separation to preserve NUA eligibility
Timing with job changes
NUA is typically most valuable when:
Record keeping complexity
With multiple employers:
Key takeaway: Multiple job holders can use NUA on company stock from any employer plan, but must keep accounts separate and coordinate the timing with job changes to maximize tax benefits.
