Potential Ripple Effects of Taxing Unrealized Capital Gains

The proposed tax on unrealized gains would be limited to those with a net worth above $100 million, but some see a broad impact on markets and businesses.

As a financial adviser with over 25 years of experience, I've seen my fair share of proposed tax changes that have sent shock waves through the investment community. However, few proposals have generated as much debate and concern as Vice President Kamala Harris' plan to tax unrealized capital gains for ultra-high-net-worth individuals. While proponents argue this would ensure the wealthiest Americans pay their "fair share," the potential implications for the stock market and broader economy are significant and warrant careful consideration.

Let's break down the key aspects of Harris’ proposal of taxing unrealized gains and examine how it could impact investors, businesses and the overall financial landscape.

The basics of Harris's proposed plan targets individuals with a net worth exceeding $100 million — about 10,660 Americans. Yes, that is a small percentage of the population, but thinking it won’t affect you would be a mistake.

The proposed tax would apply to unrealized gains — the increase in value of stock holdings and other assets that haven't been sold. This marks a dramatic shift from our current system, which taxes capital gains only at the point of sale.

The stated goal is to close what some view as a loophole allowing the ultrawealthy to indefinitely defer taxes on appreciating assets. By taxing these paper gains annually, the proposal aims to generate additional federal revenue for social programs and deficit reduction.

However, as we dive deeper, it becomes clear that the potential consequences of such a policy shift could be far-reaching and potentially disruptive to the financial markets.

A potential increase in market volatility

One of the most immediate concerns surrounding this proposal is its potential to significantly increase market volatility. The stock market is highly sensitive to changes in tax policy, and introducing a tax on unrealized gains could create a new layer of uncertainty for investors.

As wealthy individuals adjust their strategies to minimize tax liabilities, we could see more frequent trading and portfolio repositioning. This increased activity could lead to greater price fluctuations, particularly in sectors with more volatile stock prices, like technology and growth-oriented industries.

The need to regularly reassess and report asset values for tax purposes might incentivize short-term trading over long-term holding strategies. This shift could undermine market stability and lead to more unpredictable price swings. We might even see a rush to sell appreciated assets before the tax is implemented, triggering a broad sell-off and creating temporary market disruptions.

Another significant concern is how this tax could impact long-term investment strategies. The prospect of being taxed on paper gains — before those gains are realized — could discourage investors from holding on to appreciating assets for extended periods.

Long-term investment in growth stocks has traditionally been a core wealth-building strategy, particularly for those expecting their investments to appreciate over time. However, if investors face annual taxation on those gains regardless of whether they sell, the incentive to hold for the long term diminishes significantly.

Possible capital flight

The potential for capital flight is a serious concern with Harris' proposal. Wealthy individuals may choose to move their assets to more tax-friendly jurisdictions, reducing liquidity in the U.S. stock market and potentially disrupting the broader investment landscape.

This exodus of capital could have far-reaching consequences. Not only could it reduce the amount of taxable income and unrealized gains that the IRS can capture, but it could also lead to a decrease in domestic investment. This could slow economic growth and job creation, ultimately undermining the very goals the tax aims to achieve.

The valuation challenges are a Pandora's box of complexity. While publicly traded stocks have clear market values that can be easily tracked, other types of assets — such as privately held businesses, real estate or collectibles — are far more difficult to value accurately. Determining the fair market value of non-publicly traded assets is a complex and potentially contentious process that could lead to frequent disputes between taxpayers and the IRS.

For example, wealthy individuals who own private companies would need to provide accurate valuations of their businesses each year. However, these valuations can fluctuate widely depending on market conditions, earnings reports and other factors. The administrative burden of enforcing this system could overwhelm the IRS, which would need to significantly expand its capacity to handle the influx of information and audits.

Taxpayers, particularly those with complex asset portfolios, would face increased reporting requirements, legal costs and administrative burdens to comply with the new rules. This added complexity opens the door to potential tax avoidance strategies, where individuals could underreport the value of their assets or exploit loopholes to minimize their tax liabilities.

Entrepreneurship and innovation could be stifled

From a broader economic perspective, taxing unrealized capital gains could potentially stifle entrepreneurship and innovation. Many of the wealthiest individuals in the U.S. are founders of technology companies or early-stage investors who have built substantial fortunes by investing in high-growth sectors. These individuals often rely on the appreciation of their stock holdings to fund future ventures, create jobs and drive innovation.

A tax on unrealized gains could reduce the incentive for these individuals to invest in new ventures or take on the risks associated with entrepreneurship. This could slow economic growth by discouraging investment in the very sectors that drive innovation and job creation.

Small businesses, in particular, could struggle to attract investment under the new tax regime. Investors may become more cautious about putting money into startups or early-stage companies that take years to generate returns. Without a steady flow of investment into new businesses and technologies, economic dynamism could decline, leading to slower growth and reduced productivity gains over time.

The implementation of a tax on unrealized capital gains is likely to face significant legal and constitutional challenges. Until the courts resolve legal challenges, investors and businesses may be hesitant to make long-term decisions, leading to stagnation in certain sectors and a broader slowdown in economic activity.

While the full impact of taxing unrealized capital gains remains to be seen, it's clear that such a policy shift could have far-reaching implications for investors, businesses and the economy as a whole.

What you can do

For high-net-worth individuals who may be affected by this proposal, it's crucial to work closely with financial advisers and tax professionals to develop strategies that minimize potential tax liabilities while still aligning with long-term financial goals. This might involve diversifying portfolios, exploring alternative investment vehicles or considering philanthropic strategies that could help offset potential tax burdens.

You could also consider shifting out of capital gain positions and reallocating into tax-favorable options. You could consider a mega Roth to take advantage of catch-up provisions or a specially designed life insurance policy, since these contracts currently do not have limits on how much you can invest and are strategies that are easy to execute.

For the broader investing public, it's important to stay informed about these policy developments and understand how they might impact the overall market landscape. Diversification remains a key strategy for managing risk, and investors should be prepared for potentially increased market volatility.

Indeed, Harris' proposal to tax unrealized capital gains represents a significant shift in U.S. tax policy that could reshape the investment landscape as we know it. While the tax aims to address income inequality by targeting the wealthiest individuals, it also raises legitimate concerns about market volatility, reduced investment, capital flight, valuation challenges and economic growth.

Ultimately, the impact of taxing unrealized capital gains will depend on how it is implemented and how investors respond to the new tax environment.

By working with an experienced team of professionals, staying informed and focusing on your long-term financial goals, you can help yourself prepare for whatever changes may come in the tax and investment landscape.
