Not Understanding the Retirement Savings Rules Might Mean You’re Leaving Cash on the Table, Says a Financial Advisor.

Many professionals assume their steady income means they’re on track for retirement. But financial advisors say that’s the mindset that keeps people stuck—working years longer than they need to or missing out on life now. The most common and costly retirement mistake isn’t about picking the wrong stocks. It’s about making assumptions about what your income will mean for your retirement savings.

“New clients have no idea if what they’re doing will actually get them the life they want,” Ryan Greiser, a certified financial planner and founder of Opulus, told Investopedia. David Tenerelli, a senior advisor at Values Added Financial, sees something similar, often working with otherwise successful new clients who are leaving significant amounts on the table because they wrongly think they’re “too rich” to contribute to certain accounts.

The Autopilot Trap That Many Fall Into

The irony that many financial advisors see is that as new clients gain in income, they are less successful at adjusting the autopilot trap they’ve fallen into with their savings.

“The biggest issue isn’t complicated investing strategies or picking the right stocks,” Greiser said. “They’re working hard, making good money, but have no system connecting their daily decisions to their long-term goals.”

Greiser said professionals tend to fall into two opposite camps—but both are on financial autopilot. “Some are investing so aggressively they’re missing out on life today—constantly chasing the next promotion, thinking they need to work until 65,” he said. “Others are earning great money but leaving cash on the table everywhere—not negotiating raises, overpaying taxes, barely saving anything meaningful.”

Both groups share one critical problem: they can’t connect the dots between their current strategy and the future they want.

The Income Limit Myth That Costs Thousands

Others earn solid money but are holding on to outdated assumptions. “A number of clients have come to me believing that they are ineligible to make IRA contributions because of their high income,” Tenerelli said. “But many new clients are just not aware of their ability to make backdoor Roth IRA contributions instead.”

The confusion is understandable. There are income limits for deductible traditional IRA contributions and direct Roth IRA contributions. But there’s a perfectly legal workaround that many people either don’t know about or assume they can’t use: the backdoor Roth IRA strategy.

This isn’t some sketchy tax loophole—it’s a legitimate strategy that lets people contribute to Roth IRAs regardless of income level. Yet many are missing out on years of tax-free growth because they assume their income means they don’t qualify for the opportunity.

Here’s how it works: you contribute after-tax dollars to a traditional IRA (there are no income limits for nondeductible contributions), then immediately convert those funds to a Roth IRA. The result? You’ve effectively made a Roth IRA contribution despite being over the income limits.

But there’s a catch that trips up many people: the pro rata rule. If you have existing pretax IRA balances, your conversion won’t be entirely tax-free. “They also might have pretax IRA balances that would need to be eliminated in order to clear the way for tax-free conversions,” Tenerelli said.

The solution often involves rolling those pretax balances into an employer-sponsored 401(k) or converting them to a Roth (paying taxes on the conversion). It sounds complicated, but the long-term tax savings can be substantial, and a good advisor can lead you through the process.

The Bottom Line

The most common mistake financial advisors see with new clients isn’t about chasing bad investments—it’s making assumptions about what your income entails. Whether it’s skipping smart strategies or saving without a plan, these missteps cost people years of time and thousands in potential savings.
