What is the net unrealized appreciation (NUA) strategy?

Retirement & 401(k)advanced3 answers · 5 min readUpdated February 28, 2026

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:

  • Company stock current value: $800,000
  • Original cost basis: $200,000
  • Net unrealized appreciation: $600,000
  • Other 401(k) investments: $300,000

  • Without NUA strategy (traditional rollover):

  • All withdrawals taxed as ordinary income at 37% rate
  • $800,000 withdrawal = $296,000 in taxes

  • With NUA strategy:

  • Pay ordinary income tax on basis: $200,000 × 37% = $74,000
  • Pay capital gains on NUA when sold: $600,000 × 20% = $120,000
  • Total tax: $194,000
  • Tax savings: $102,000

  • Qualifying requirements for NUA


  • Triggering event: Separation from service, disability, death, or reaching age 59½
  • Lump sum distribution: Entire plan balance distributed within one tax year
  • Employer securities: Strategy applies only to company stock, not other investments
  • Cost basis records: Your plan must track the original purchase price

  • Advanced timing considerations


    The strategy becomes more valuable when:

  • NUA exceeds 20-30% of the stock's current value
  • You're in a high tax bracket (32%+ ordinary income)
  • You expect to hold the stock for over one year (long-term capital gains)
  • Your state has high ordinary income tax but favorable capital gains treatment

  • 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):

  • Takes NUA distribution, pays $55,500 in ordinary income tax (37% bracket)
  • Sells $100,000 worth annually over 6 years
  • Stays in 15% capital gains bracket instead of 20%
  • Additional savings: $30,000 over the selling period

  • Medicare and Social Security considerations


    Large NUA distributions can:

  • Trigger Medicare high-income surcharges (IRMAA)
  • Cause Social Security benefits to become taxable
  • Push you into higher tax brackets temporarily

  • 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:

  • NUA applies only to the plan with employer securities
  • Other plans can be rolled over normally to IRAs
  • Don't consolidate company stock with other accounts before using NUA

  • Example: Strategic plan management


    An employee changing jobs has:

  • Current company 401(k): $400,000 (including $200,000 company stock)
  • Previous employer 401(k): $150,000 (no company stock)
  • IRA rollover: $75,000

  • 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:

  • You've accumulated significant stock appreciation over many years
  • You're leaving the company (separation from service)
  • You're moving to a lower tax bracket situation

  • Record keeping complexity


    With multiple employers:

  • Each plan tracks cost basis differently
  • Some plans may not offer NUA (no company stock)
  • ESPP purchases outside 401(k) don't qualify
  • Stock acquired through different programs may have different basis calculations

  • 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.
