Many high earners are sitting on a goldmine, but they might not even know it. Enter the mega backdoor Roth—a fancy term for a strategy that can help them stash away an extra $47,500 a year. Sounds enticing, right? Here’s the scoop: high earners can make after-tax contributions to their 401(k) plans and then roll that money into a Roth IRA.
But wait! Not every 401(k) plan is a willing participant in this party. Participants need to check with their providers to see if after-tax contributions and Roth conversions are allowed. Spoiler alert: over 70% of plans do, so chances are good.
Now, let’s break down the numbers. The combined limit for 401(k) contributions is a whopping $72,000 for 2026. If you’re 50 or older, you get a bonus bump to $80,000. It’s like a senior discount, but for retirement savings. Additionally, employees aged 50+ can contribute an extra catch-up contribution of $7,500 on top of these limits, enhancing their retirement savings potential.
The 401(k) contribution limit hits $72,000 for 2026, with a sweet $80,000 bonus for those 50 and older!
And here’s the kicker: high earners can actually contribute up to 100% of their compensation into their 401(k) through these after-tax provisions. That’s right—no more fretting over pesky income caps that limit Roth IRA contributions. IRS Notice 2014-54 enables this strategy, allowing high-income earners to maximize their retirement savings.
The tax advantages are where this strategy really shines. After-tax contributions can grow tax-free once converted to Roth IRAs. Since the principal was already taxed, there’s no tax hit during the conversion. It’s like getting a free pass to the amusement park, but for your money.
Meanwhile, investment earnings on those contributions enjoy tax-deferred compounding while they’re still cozy in the employer plan. Just as bundling policies can unlock savings on auto insurance, combining multiple retirement strategies can compound the overall financial benefit.
But here’s the catch: not every 401(k) plan automatically lets you do this. Employees need to double-check with HR to verify their plans allow the mega backdoor Roth magic. If not, it’s like showing up to a party that’s already over.
And while it’s tempting to dive headfirst into after-tax contributions, it’s wise to maximize the employer match first. After all, that’s free money—like finding a $20 bill in your coat pocket.
