Could you be a ‘hidden millionaire?’

A development has been unfolding that’s taken many Americans by surprise. Much like snow drifting down silently overnight, wealth has a tendency to creep up: through steady salary hikes, 401(k) contributions, stock options, growing home equity, and inheritances. It builds up as you go about your daily life. If your financial self-perception hasn’t kept up—understandably influenced more lately by rising prices, competing demands on your disposable income, and that common thought of “I’d feel secure if I earned more“—you’re far from alone. A found nearly 30% of millionaires feel their finances dictate their lives.  

Still, a net worth in the millions, built up over time, brings with it financial advantages and intricacies that can readily lead to errors—such as an unexpected tax bill or family disputes following an inheritance. Acknowledging that your financial circumstances have outpaced your self-perception (my husband and I have experienced this firsthand!) is the initial step.

If you’ve found yourself in the fortunate position of “hidden millionaire,” here are three common pitfalls we see, and simple ways to get ahead of them.

Mistake #1: Sitting on excess cash, or other uses of savings, while still paying high-interest debt.

Many individuals feel more secure with a substantial cash reserve, particularly after periods of market instability. However, if your credit card interest rate exceeds the return on your cash holdings, the financial equation reverses. You stand to lose significantly more than you gain. 

Even maximizing retirement contributions should be reconsidered when carrying high-interest debt. We often observe this among disciplined savers. These trade-offs can quietly erode long-term wealth. 

The fix: Prioritize paying off any debt with an interest rate above approximately 8% before boosting long-term 401(k) contributions. Always contribute enough to secure your employer’s match (it’s essentially free money!) but allocate the remaining funds to reducing high-interest debt. Keep at least three months’ worth of emergency savings in an account with a competitive yield, and invest the rest using a long-term, tax-efficient strategy. Automate what you can and rebalance your portfolio periodically.  

Mistake #2: Not updating your tax strategy for your new normal.

As wealth grows incrementally, we observe many individuals assuming their tax scenario stays straightforward. Yet as financial complexity increases, so do the chances of missing optimization opportunities or making errors. Vested stock generates taxable income. Dividends and capital gains add up. Tax-advantaged accounts become comparatively more valuable. Tax-efficient diversification and strategic allocation across different account types become both feasible and essential. 

Hidden millionaires often overlook powerful tools that can help reduce taxes, build flexibility, and strengthen long-term wealth. 

The fix: Conduct a proactive tax review outside of the April tax rush. Examine the vesting dates of your stock awards, the timing of your bonus, and any expected gains to avoid tax-time surprises. Strategically utilize tax-advantaged accounts: maximize contributions to Health Savings Accounts, consider Roth conversions, contribute to a 529 plan for state tax benefits, and assess your strategy for taxable versus tax-advantaged accounts. Treat tax efficiency as found money—because that’s exactly what it is.

Mistake #3: Failing to create or update your financial or estate plan. 

Once you identify as a “hidden millionaire,” it’s time to safeguard what you’ve accumulated. You’ve built something significant, and you have the power to determine its longevity. To spare your family financial or emotional hardship, start planning now. Almost a quarter of millionaires lack estate planning documents—your family will be grateful not to be part of that group.   

The fix: If you lack a will, designated beneficiaries, or healthcare directives, begin by creating these. If you already have them, update them every three years or after significant life events. Review your insurance coverage to ensure your assets and family are sufficiently protected. And if you anticipate receiving or transferring wealth, plan ahead for taxes, timing, and structure.

Sounds complicated? It doesn’t have to be.

Most people still feel “not particularly wealthy” even when the numbers suggest otherwise. Rising expenses, market fluctuations, and financial worry can overshadow one’s financial self-image. If you lack the time, expertise, or (let’s be frank!) the interest to manage your financial details, you don’t have to tackle it alone. Professional guidance can save time, minimize costly errors and stress, and prevent emotions from dictating your choices. 

If you’re thinking, “this describes me,” take a moment to pause and recognize the progress you’ve achieved. Now is the time to align your perception of your financial life with its actual reality. Your future self—and your family—will be grateful.
