Unlocking the Benefits of Net Unrealized Appreciation for Tetra Tech Employees: A Guide to Smart Retirement Planning

Healthcare Provider Update: Tetra Tech's Healthcare Provider Insight Tetra Tech currently partners with various health insurance providers to deliver healthcare benefits to its employees, including prominent insurers in the marketplace. As employees prepare for upcoming benefits changes, it is critical to understand the intricacies of their coverage and options. In 2026, Tetra Tech employees are likely to experience significant increases in healthcare costs, driven by broader industry trends. With anticipated premium hikes in the Affordable Care Act (ACA) marketplace reaching over 60% in some states, many employees could see their out-of-pocket expenses soar. Factors contributing to this include the potential expiration of enhanced federal subsidies and broader medical cost inflation, which are expected to add substantial financial pressure on individuals. Consequently, Tetra Tech employees should proactively review their healthcare options and budget for potentially higher expenditures in the coming year, ensuring they are equipped to handle these economic challenges.

All investing involves risk, including the  possible loss of principal, and there is no  guarantee that any investment strategy will  be successful.  This discussion explains  the tax treatment that may be available when  employer stock is held in a qualified retirement  plan. I t is important for our Tetra Tech Clients to understand that any  shares of stock held in a retirement plan, including  shares of Tetra Tech's stock, can lose some or  all of their value over time.

 

If you participate in a 401(k), ESOP, or another qualified retirement plan that lets you invest in Tetra Tech's stock, you need to know about net unrealized appreciation — a simple tax deferral opportunity with an unfortunately complicated name.

When you receive a distribution from Tetra Tech's retirement plan, the distribution is generally taxable to you at ordinary income tax rates. A common way of avoiding immediate taxation is to make a tax-free rollover to a traditional IRA. However, when you ultimately receive distributions from the IRA, they'll also be taxed at ordinary income tax rates. (Special rules apply to Roth and other after-tax contributions that are generally tax-free when distributed.) But if your distribution includes Tetra Tech stock (or other Tetra Tech securities), you may have another option — you may be able to defer paying tax on the portion of your distribution that represents net unrealized appreciation (NUA). You won't be taxed on the NUA until you sell the stock. What's more, the NUA will be taxed at long-term capital gains rates — typically much lower than ordinary income tax rates. This strategy can often result in significant tax savings.

What Is Net Unrealized Appreciation?

A distribution of employer stock consists of two parts: (1) the cost basis (that is, the value of the stock when it was contributed to, or purchased by, your plan), and (2) any increase in value over the cost basis until the date the stock is distributed to you. This increase in value over basis, fixed at the time the stock is distributed in-kind to you, is the NUA. For example, assume you retire from Tetra Tech and receive a distribution of Tetra Tech stock worth $500,000 from your 401(k) plan, and that the cost basis in the stock is $50,000. The $450,000 gain is NUA.

How Does It Work?

At the time you receive a lump-sum distribution that includes Tetra Tech stock, you'll pay ordinary income tax only on the cost basis in the Tetra Tech securities.

You won't pay any tax on the NUA until you sell the securities. At that time the NUA is taxed at long-term capital gain rates, no matter how long you've held the securities outside of the plan (even if only for a single day). Any appreciation at the time of sale in excess of your NUA is taxed as either short-term or long-term capital gain, depending on how long you've held the stock outside the plan.

Using the example above, you would pay ordinary income tax on $50,000, the cost basis, when you receive your distribution. (You may also be subject to a 10% early distribution penalty if you're not age 55 or totally disabled.) Let's say you sell the stock after ten years, when it's worth $750,000. At that time, you'll pay long-term capital gains tax on your NUA ($450,000). You'll also pay long-term capital gains tax on the additional appreciation ($250,000) since you held the stock for more than one year. Note that since you've already paid tax on the $50,000 cost basis, you won't pay tax on that amount again when you sell the stock.

If your distribution includes cash in addition to the stock, you can either roll the cash over to an IRA or take it as a taxable distribution. And you don't have to use the NUA strategy for all of Tetra Tech's stock — you can roll a portion over to an IRA and apply NUA tax treatment to the rest.

What Is A Lump-Sum Distribution?

In general, you're allowed to use these favorable NUA tax rules only if you receive Tetra Tech securities as part of a lump-sum distribution. To qualify as a lump-sum distribution, both of the following conditions must be satisfied:

• It must be a distribution of your entire balance, within a single tax year, from all of Tetra Techs qualified plans of the same type (that is, all pension plans, all profit-sharing plans, or all stock bonus plans)
• The distribution must be paid after you reach age 59½, as a result of your separation from service, or after your death

There is one exception: even if your distribution doesn't qualify as a lump-sum distribution, any securities distributed from the plan that were purchased with your after-tax (non-Roth) contributions will be eligible for NUA tax treatment.

Cost basis — $50,000	Taxed as ordinary income rates; 10% early payment penalty tax if you're not 55 or disabled

Tax Payable At Sale — Stock Valued at $750,000
Cost basis — $50,000	Already taxed at distribution; not taxed again at sale
NUA — $450,000	Taxed at long-term capital gains rates regardless of holding period
Additional appreciation — $250,000	Taxed as long- or short-term capital gain, depending on holding period outside plan (long-term in this example)

NUA Is For Beneficiaries, Too

If you die while you still hold Tetra Tech securities in your retirement plan, your plan beneficiary can also use the NUA tax strategy if he or she receives a lump-sum distribution from the plan. The taxation is generally the same as if you had received the distribution. (The stock doesn't receive a step-up in basis, even though your beneficiary receives it as a result of your death.) If you've already received a distribution of Tetra Techs stock, elected NUA tax treatment, and die before you sell the stock, your heir will have to pay long-term capital gains tax on the NUA when he or she sells the stock. However, any appreciation as of the date of your death in excess of NUA will forever escape taxation because, in this case, the stock will receive a step-up in basis. Using our example, if you die when your employer stock is worth $750,000, your heir will receive a step-up in basis for the $250,000 appreciation in excess of NUA at the time of your death. If your heir later sells the stock for $900,000, he or she will pay long-term capital gains tax on the $450,000 of NUA, as well as capital gains tax on any appreciation since your death ($150,000). The $250,000 of appreciation in excess of NUA as of your date of death will be tax-free.

Some Additional Considerations

• If you want to take advantage of NUA treatment, make sure you don't roll the stock over to an IRA. That will be irrevocable, and you'll forever lose the NUA tax opportunity.
• You can elect not to use the NUA option. In this case, the NUA will be subject to ordinary income tax (and a potential 10% early distribution penalty) at the time you receive the distribution.
• Stock held in an IRA or employer plan is entitled to significant protection from your creditors. You'll lose that protection if you hold the stock in a taxable brokerage account.
• Holding a significant amount of employer stock may not be appropriate for everyone. In some cases, it may make sense to diversify your investments.*
• Be sure to consider the impact of any applicable state tax laws.

When Is It The Best Choice?

In general, the NUA strategy makes the most sense for individuals who have a large amount of NUA and a relatively small cost basis. However, whether its right for you depends on many variables, including your age, your estate planning goals, and anticipated tax rates. In some cases, rolling your distribution over to an IRA may be the better choice. And if you were born before 1936, other special tax rules might apply, making a taxable distribution your best option.
