New Update: Healthcare Costs Increasing by Over 60% in Some States. Will you be impacted?

Workday Employees: Handling Single-Stock Concentration with a Section 351 Strategy

Healthcare Provider Update: Healthcare Provider for Workday: Workday, the leading provider of enterprise cloud applications for finance and human resources, typically partners with large health insurance carriers such as UnitedHealthcare, Anthem (Elevance Health), and Aetna to deliver healthcare benefits to its employees. These partnerships ensure that employees have access to comprehensive healthcare plans that cater to a diverse workforce. Potential Healthcare Cost Increases in 2026: As we move into 2026, employees at Workday may face significant hikes in their healthcare costs. With projections indicating premium increases exceeding 60% in some states and a potential average rise of 18% nationally, many employers, including Workday, are likely to adjust their benefits structure. This shift could result in higher deductibles and out-of-pocket expenses for employees, particularly if enhanced federal subsidies expire. Workers are encouraged to stay informed about benefit changes and strategize their healthcare spending to mitigate these impending cost increases. Click here to learn more

The Strategic Potential of Section 351: An Analysis of a Multi-Stock Case in Tax-Deferred Reorganization

A sizable amount of the wealth of many high-earning professionals at Workday may be invested in a small number of highly valued equities, including company shares accumulated through restricted stock units (RSUs), the employee stock purchase plan (ESPP), or equity awards earned due to long tenure. While rebalancing may seem out of reach due to the tax ramifications of selling these positions, investors can make tax-deferred contributions of appreciated assets to a new business entity through a Section 351 exchange. When an investor wants to manage several sizable, embedded gains at once, this tactic may be especially useful.

Think about James, a client with a $10 million portfolio. The value of one stock investment, which he purchased for $50,000, has increased to $1 million, or 10% of his total portfolio. At a long-term capital gains rate that can reach 23.8% for certain high-income taxpayers (20% maximum long-term capital gains rate plus the 3.8% Net Investment Income Tax), selling this position would result in a $950,000 capital gain and an estimated $226,100 tax bill. The amount available for reinvestment would be reduced by this tax.

Section 351(a) of the Internal Revenue Code provides: “If property is transferred to a corporation by one or more persons solely in exchange for stock in such corporation and immediately after the exchange such person or persons are in control (as defined in section 368(c)) of the corporation, no gain or loss shall be recognized.” Under Section 368(c), “control” generally means ownership of at least 80% of the voting power and 80% of each class of non-voting shares.

The transferor or transferors must own at least 80% of the new corporation’s stock right after the exchange to qualify for this treatment. This can be done for investors with sizable portfolios by joining a larger seeding group or acting as the principal seeder of a new entity.

In a Section 351 transaction, any built-in gains are preserved because the shareholder’s basis in the received stock typically carries over from the contributed property. If the shares are held until death, a step-up in basis under Section 1014 may eliminate the deferred gain.

Another client example involves Sarah, who has a $13 million portfolio. She owns two appreciated stocks:

Stock A: Originally $300,000, now worth $3 million.
Stock B: Initial cost basis $500,000, now worth $3 million.

At a long-term capital gains rate that can reach 23.8% for certain high-income taxpayers, the aggregate unrealized gain of $5.2 million would translate into an estimated tax of roughly $1,237,600 if sold today, which can constrain portfolio adjustments.

For employees of Workday holding concentrated positions, taking part in a Section 351 exchange can reduce concentration risk and defer recognition of these gains without an immediate tax bill. If assets receive a step-up in basis at death, the deferred gain may be fully eliminated under current law, and deferral can provide flexibility in managing future tax obligations.
