About this Episode 

Most retirement savers know their 401(k) is their biggest account. What many don’t realize is just how many rules, fees, and strategies surround these plans, and how costly missteps can be. 

On this episode of GDS Unplugged, adviser Tim Allin, CFP®, CEPA®, shared insights on everything from early withdrawal provisions to the much-talked-about “Mega Backdoor Roth.” Below are the highlights. 

The Hidden Costs of a 401(k) 

It’s common for participants to assume their workplace plan is “free.” In reality, most plans come with layers of: 

  • Investment expenses (fund expense ratios),
  • Administrative fees, and
  • Service charges for plan management. 

Fees aren’t necessarily negative, but if you’re paying them, you should be receiving value in return, whether that’s financial planning, tax coordination, or investment guidance. Without that, fees can eat into long-term returns without providing real benefits. 

Required Minimum Distributions: Avoiding Penalties 

Starting at age 73 (age 75 for those born in 1960 or later), the IRS requires savers to begin taking Required Minimum Distributions (RMDs) from tax-deferred accounts. 

Key facts: 

  • Missing an RMD can result in a penalty of 25% of the required amount (reduced to 10% if corrected quickly).
  • IRAs can be aggregated; you may take the combined RMD from any single IRA.
  • 401(k)s must be drawn individually. If you have multiple older plans, you must take separate distributions from each one. 

This is one reason consolidating accounts before RMD age can reduce both stress and paperwork. 

Retiring Early? Strategies for Accessing Funds 

Leaving the workforce before 59½ doesn’t mean funds are locked away forever. Two IRS provisions offer potential options: 

  • Rule of 55: If you separate from service in or after the year you turn 55 (50 for certain public-safety workers), you may access that employer’s 401(k)/403(b) without the 10% early withdrawal penalty.
  • Rule 72(t): Allows penalty-free withdrawals from IRAs and some other accounts at any age, but requires a rigid schedule of withdrawals for at least five years or until 59½, whichever is longer. Breaking the schedule can result in retroactive penalties. 

Both options require careful planning, and in some cases, consultation with a CPA or financial professional. 

Target-Date Funds: Convenient, but Not Custom 

Target-date funds (TDFs) are designed to automatically adjust from stocks to bonds as a “target” retirement year approaches. While simple, they come with drawbacks: 

  • Limited customization: Everyone with the same retirement year gets the same allocation, regardless of risk tolerance.
  • Relatively high costs: Expense ratios may run higher than index alternatives.
  • Market timing risks: Rebalancing may force sales at inopportune times. 

TDFs can work well as a default choice, but they are not one-size-fits-all. 

The Mega Backdoor Roth: Maximizing Contribution Options 

Some employer-sponsored plans allow an advanced strategy known as the Mega Backdoor Roth. Here’s how it works: 

  • For 2025, employees may defer up to $23,500 (plus catch-up contributions for those 50+).
  • With employer matches, total contributions may reach around $40,000.
  • The IRS “annual additions limit” allows even more, often up to $70,000 in combined contributions.
  • Certain plans permit participants to make after-tax contributions above the standard deferral, then convert those dollars into Roth. 

When available, this strategy may provide an opportunity to expand the amount of retirement money that grows tax-free. However, rules vary by employer, so checking plan documents or calling the provider is essential. 

Business Owners: Why Exit Planning Needs a Team 

For business owners, selling a company is often a once-in-a-lifetime event. Yet some research shows that 70–80% of businesses that go to market never sell, and among those that do, most owners report regret within a year, according to the Exit Planning Institute 

The difference often comes down to planning. Successful exits typically involve a core team: attorney, CPA, wealth manager, and in some cases family or business partners. Just like surgery requires coordination among specialists, business sales benefit from a “quarterback” ensuring communication, accountability, and follow-through. 

Key Takeaway 

The common thread across all these strategies, from RMDs and early withdrawals to Roth conversions and exit planning, is the need for preparation. Most mistakes occur not because people lack the intelligence to choose well, but because they never had the right information or a clear plan. 

With proper planning, clients may reduce the likelihood of penalties, better manage fees and align strategies with their long-term goals.
