What Maxing Out a 401(k) Really Means for High Earners
For tech professionals navigating vesting schedules and complex equity, “maxing out” a 401(k) is rarely the end of the conversation. It's usually just the start of a more difficult set of questions.
We occasionally get clients who ask, “What actually happens after I hit my 401(k) limit?” Or perhaps more importantly, “Should I even be maxing out my 401(k) right now? Is that cash better served in a taxable brokerage account for liquidity?”
If you're staring at a heavy RSU vest or a hefty bonus and trying to decide where those funds will work hardest, here’s what maxing out a 401(k) really means for a high earner in 2026.
Is "Maxing" Higher Than You Think?
Most people think "maxing out" ends at the IRS elective deferral limit. For 2026, that’s $24,500.
But for high-income tech professionals, that’s just the start. Most tech firms (Google, Meta, Amazon, and Microsoft) have 401(k) plans set up to allow for after-tax contributions and the conversion to Roth.
In other words, your plan likely allows the Mega Backdoor Roth.
The Mega Backdoor Roth allows for higher contribution limits and tax-free growth – without any income caps. A lot of our clients don’t know about the Mega Backdoor Roth or think it sounds too good to be true, but it’s completely real. And it's one of our favorite strategies.
With the Mega Backdoor Roth, your true "max" is the Section 415(c) limit, which is $72,000 for 2026. This $72k ceiling is an "all-in" number that includes:
Your $24,500 pre-tax or Roth deferral.
Your Employer Match (This varies. See chart below).
Your After-Tax contributions (The "Mega" portion).
Catch Up Contributions
If you’re age 50+, your total limit jumps to $80,000 via an $8,000 catch-up. For those aged 60-63, the new "Super Catch-up" pushes that capacity to $83,250 ($72k base + $11,250 catch-up).
New SECURE Act 2.0 Rule for 2026: Per SECURE 2.0, if you earned more than $150,000 in FICA wages in 2025, the IRS now mandates that your 2026 catch-up contributions must be made as Roth (after-tax). You can no longer take a tax deduction on that extra $8,000 or $11,250. This is a forced "tax-now" move for almost every high-earning tech professional.
401(k) Contribution Limits for Google, Microsoft, and Meta employees
| Category | 2026 |
|---|---|
| Pre-tax/Roth (Employee) | $24,500 |
| 50% Employer Match (For Google, Microsoft, and Meta*) | $12,250 |
| After-Tax (For Google, Microsoft, and Meta) | $35,250 |
| Total (Employee + Employer) | $72,000 |
| Total for ages 50-59, 64+ (Employee + Employer + Catch-Up) | $80,000 |
| Total for ages 60-63 (Employee + Employer + "Super" Catch-Up) | $83,250 |
*One main difference for Meta: Unlike many other employers, Meta’s 50% match also applies to catch-up contributions. If you contribute $8,000 in catch-ups, they’ll kick in another $4,000 on your behalf. However, Meta’s contribution will still count toward the $72,000 limit.
401(k) Contribution Limits for Amazon employees
| Category | 2026 |
|---|---|
| Pre-tax/Roth (Employee) | $24,500 |
| 50% match on the first 4% of eligible pay (Amazon) | $7,200 |
| After-Tax (Amazon) | $40,300 |
| Total (Employee + Employer) | $72,000 |
| Total for ages 50-59, 64+ (Employee + Employer + Catch-Up) | $80,000 |
| Total for ages 60-63 (Employee + Employer + "Super" Catch-Up) | $83,250 |
The Real Tax Impact (and its Limits)
For high earners, the 401(k) is an exercise in tax arbitrage.
At $350k–$450k income: You’re likely in the 35% federal bracket. Maxing the $24,500 pre-tax limit saves you roughly $8,575 in immediate federal taxes.
At $700k+ income: You are firmly in the 37% bracket. That same contribution saves you $9,065 in federal taxes.
Tax Deferral vs. Long-Term Planning
It’s important to remember that traditional 401(k) contributions defer taxes, not eliminate them. You’re essentially making a bet that your tax rate today (37%) is higher than it will be when you withdraw the money in retirement.
However, many of our clients at Google or Amazon will have massive taxable brokerage accounts and RSU-driven wealth. By the time Required Minimum Distributions (RMDs) kick in at age 73 (scheduled to rise to 75 in 2033), those distributions could easily push you back into the 37% bracket anyway.
If you expect to be in a high bracket forever, you might actually prioritize Roth contributions for the entire $72,000+ limit. This "locks in" today’s tax rates and ensures your heirs receive the money 100% tax-free, which is often the superior long-term play for estate planning.
Liquidity vs. Tax Efficiency Trade-Off
The question we hear most often from tech employees isn’t about the math. It’s about access. “If I max out my 401(k), am I locking away the money I might need for a lucrative investment, down payment, or sabbatical?”
For high earners, the decision to prioritize a taxable brokerage account (or other high-return investment) over a 401(k) usually boils down to three factors:
1. Your Bridge to Retirement
If you plan to "retire" (or transition to lower-paying consulting/passion projects) at 45 or 50, you need a "bridge" of accessible capital to cover your expenses until you can touch your 401(k) penalty-free at 59.5.
High earners often over-index on tax-advantaged accounts and end up "401(k) wealthy" but "cash poor." If your taxable brokerage account isn't large enough to sustain 5–10 years of your lifestyle, you might actually choose to stop at the 401(k) match and redirect the rest to a brokerage account.
2. Opportunity Cost of Locked Capital
In 2026, the tax drag on a taxable account (capital gains and dividends) is real, but so is the flexibility.
One option is a Core/Satellite approach. Use the 401(k) for your "core" retirement (the money you absolutely won't touch). Use the taxable brokerage for your "satellite" goals, like real estate ventures, angel investing, or a rainy-day fund.
If you're in the 37% bracket, the $9,065 you save by maxing your pre-tax 401(k) is essentially a "risk-free return" on that capital. You would need to earn significantly higher returns in a taxable account just to "break even" with the immediate tax savings of the 401(k).
3. RSU Liquidity as a Safety Valve
The unique advantage of working at a firm like Google or Amazon is your RSU vesting schedule. Because you have a steady stream of "cash-like" equity hitting your account every quarter (or even every month at some levels), you may not actually need to prioritize a taxable account for liquidity as much as a standard earner would.
Many of our clients treat their vested RSUs as their primary liquidity pool. This allows them to "aggressively" max out the 401(k) and Mega Backdoor Roth because they know the next vest is only 30–90 days away.
Coordinating with RSUs and Bonuses
In tech, your cash flow is "lumpy." You might have a comfortable base salary, but RSU vests and performance bonuses boost your income at various points around the year.
Depending on your situation, you might want to think beyond the standard flat 10% 401(k) contribution. Many high earners use their bonus or RSU-heavy months to "super-fund" their 401(k). By setting your deferral rate to 50% or even 80% during a vest month, you can hit your $24,500 limit earlier in the year (which means getting your capital into the market sooner).
Just make sure your company has a "True-Up" provision. If you max out your 401(k) by June and your company doesn't offer a true-up, you could lose the employer match for the remaining six months of the year.
The "Waterfall" After the 401(k)
For someone earning $500k+, a 401(k) (even a maxed one) only represents a small fraction of your necessary income in retirement.
Once you’ve maxed out your 401(k) at that $72,000 ceiling, the "Investment Waterfall" moves to other assets. High-net-worth portfolios require strategic asset location that puts the right assets in the right tax buckets.
Health Savings Account (HSA): If you have a High Deductible Health Plan, max this next ($4,400 individual / $8,750 family for 2026). It’s the only "triple-tax-advantaged" account.
Backdoor Roth IRA: Even if you make $1M, you can still put $7,500 ($8,600 if 50+) into a Roth IRA via the standard backdoor Roth IRA method. This is different from (and could be in addition to) the Mega Backdoor Roth we talked about before.
Taxable Brokerage: This is where RSU proceeds usually land. Focus on Tax-Loss Harvesting here to offset the capital gains from your vesting shares.
Charitable Giving (DAF): For those at the $700k+ level, charitable vehicles such as a Donor-Advised Fund can offer significant tax deductions while supporting a cause you care about. Donating appreciated assets (such as your RSUs) avoids the capital gains tax on the vest and provides a full fair-market-value deduction.
Depending on your situation and what you’re comfortable with, you have plenty of other options, too.
If you have kids or grandkids, consider contributing to their 529 plan. You can do this via gifts, and even bundle multiple years at once (called “superfunding”). While they don’t offer any federal tax deductions, your state may offer other incentives, like deductions or credits. It also sets up your loved ones with tax-advantaged funds for their education down the road.
Private investing and real estate are yet more options, but bear in mind that they come with their share of risks and challenges. They can diversify your portfolio and offer the potential for substantial returns, but they’re also illiquid in nature and tend to be riskier.
Experience the Financial Confidence You Deserve
Optimizing "lumpy" RSU income, complex 401(k) structures, and evolving IRS mandates requires more than a standard “cookie-cutter” financial plan. And on top of work obligations and the time you’d rather spend with loved ones, it’s a lot to tackle by yourself.
