If you’re a high earner, you’ve probably heard this advice a hundred times: “Max out your 401(k). It’s the smartest tax move you can make.”
It’s well-meaning advice, and it’s not necessarily wrong, but for many successful professionals, it’s incomplete. Because what most people call “tax savings” in a 401(k) isn’t really saving at all. It’s tax deferral, and deferring taxes without a plan for how or when you’ll pay them can set up what we call the 401(k) trap.
The Tax Time Bomb No One Talks About
When you put money into a traditional 401(k), you’re saving on taxes today — but you’re agreeing to pay them later, at whatever rates exist in the future. As those pre-tax balances grow, so does your future tax liability. By the time you reach your 70s, required minimum distributions (RMDs) can push you into a higher bracket than you ever expected.
The result?
- Higher taxable income in retirement
- Bigger Medicare premiums (thanks to IRMAA surcharges)
- Taxation of up to 85% of Social Security benefits
In other words, the “tax shelter” you relied on becomes a tax torpedo.
The Smarter Approach: Tax Diversification
The fix isn’t to stop saving; it’s to save strategically. Instead of automatically maxing pre-tax contributions, consider blending:
- Roth contributions for tax-free withdrawals later
- Taxable accounts for flexibility and favorable capital gains rates
- HSA or after-tax 401(k) options where available
A mix of account types gives you control over when and how you recognize income, which can dramatically lower your lifetime tax bill.
At Hanover Advisors, we often tell clients that wealth isn’t just about what you earn—or even what you save—it’s about what you keep. The right tax balance can mean the difference between a comfortable retirement and a constrained one, especially for high earners.
It’s not about saving more. It’s about saving smarter.
