5 Critical RMD Mistakes That Could Decimate Your Retirement Savings

June 29, 2026

If you hate paying taxes now, just wait until you turn 73 when you’re likely to be on a fixed income. That's when Required Minimum Distributions (RMDs) force you to withdraw money from your retirement accounts whether you want to or not.

‍

Most soon-to-be retirees ignore or underestimate the impact of RMDs on their retirement savings. If you don't take steps to protect yourself now, you could lose a significant chunk of your hard-earned money to the government.

‍

What are RMDs - (Required Minimum Distributions)?

‍

RMDs are mandatory withdrawals from your retirement accounts that begin at age 73. These apply to:

‍

  • Traditional IRAs
  • 401(k)s
  • SEP IRAs
  • SIMPLE IRAs
  • 403(b)s
  • 457 plans
  • Keogh plans

‍

Uncle Sam has been patient while you've deferred taxes during your working years. But at 70½, that patience runs out.

‍

How RMDs Are Calculated

‍

The basic formula for calculating your RMD is: Account balance as of December 31 of previous year ÷ Life expectancy factor = Required Minimum Distribution

‍

Let's look at an example:

‍

  • John is 75 years old
  • His IRA balance on December 31 was $500,000
  • His life expectancy factor, according to the IRS table, is 22.9
  • His RMD would be $500,000 ÷ 22.9 = $21,834

‍

This means John must withdraw at least $21,834 this year, whether he needs the money or not.

‍

Mistake #1: Not Taking RMDs On Time

‍

The penalty for missing an RMD is severe: 50% of what you should have taken. That's the highest penalty levied by the IRS.

‍

Consider this scenario:

‍

  • Required distribution you are required to withdraw: $20,000
  • But you missed taking the distribution
  • The tax penalty applied: $10,000 (50% of $20,000)
  • Plus, you still have to pay regular income taxes on that $20,000 (even though you didn’t withdraw it)
  • The total cost for this mistake could exceed $16,000 on a $20,000 missed withdrawal
  • Leaving you just $4,000 of the original $20,000

‍

Mistake #2: Calculating RMD Amounts Incorrectly

‍

Your RMD is based on your account balances at the end of the previous year. Many retirees make the mistake of using current balances or incorrect life expectancy tables.

‍

The B.O.S.S. Retirement team recently worked with an engineer who had saved $1.6 million for retirement. Let's break down his potential tax liability without proper planning:

‍

  • RMD taxes over lifetime: $763,256
  • Taxes on reinvested RMDs: $283,990
  • Estate taxes on remaining balance: $512,717
  • Total tax burden: $1,559,963

‍

With proper planning, his tax burden was reduced to $440,574 - a savings of over $1.1 million.

‍

Mistake #3: Taking RMDs From The Wrong Accounts

‍

A common error is thinking you can aggregate all your retirement accounts together. While you can combine IRAs, 401(k)s must have their own separate RMDs.

‍

Here's a real-world example:

‍

  • Husband's RMD requirement: $4,000 from his 401 (k)
  • Wife's RMD requirement: $2,000
  • Taking $6,000 from just one spouse's account doesn't satisfy both requirements
  • Result: 50% penalty on the untouched account

‍

Understanding Account Aggregation Rules

‍

You can aggregate:

‍

  • Traditional IRAs
  • SEP IRAs
  • SIMPLE IRAs
  • Rollover IRAs

‍

You cannot aggregate:

‍

  • 401(k)s
  • 403(b)s
  • Inherited IRAs
  • Roth IRAs (no RMDs required)

‍

Mistake #4: Not Coordinating RMDs With Social Security

‍

Your RMD income could push you into a higher tax bracket and cause up to 85% of your Social Security benefits to become taxable.

‍

Let's look at a real B.O.S.S. Retirement Solutions client example:

‍

  • Age 69 tax burden: $16,555
  • Age 71 tax burden: $31,720
  • Age 80 tax burden: $54,179

‍

This tripling of tax burden wasn't due to tax rate changes - it was caused by the compounding effect of RMDs and Social Security taxation.

‍

Mistake #5: Waiting Too Long To Create An RMD Strategy

‍

Many people think deferring taxes as long as possible is the smart move. However, this creates what financial professionals call a "tax torpedo" in retirement.

‍

Consider this example from a recent B.O.S.S. Retirement client:

‍

  • Initial IRA balance: $660,853
  • Total taxes without planning (ages 70½ to 90): $941,334
  • Taxes with proper planning: $218,081
  • Tax savings: $723,253

‍

The Social Security Tax Trap

‍

For married couples in 2024:

‍

  • Combined income over $44,000: up to 85% of benefits taxable
  • Combined income includes:
    • Half of Social Security benefits
    • All other income, including RMDs
    • Tax-exempt interest

‍

Strategic Solutions for RMD Management

‍

The Power of Forward-Looking Tax Planning

‍

Traditional tax preparation looks backward at what's already happened. What you need is forward-looking tax planning that considers:

‍

  • Future tax rates
  • Social Security taxation
  • Medicare premium increases
  • Estate tax implications
  • Roth conversion opportunities

‍

Take Action Now: The Time Window Is Limited

‍

The Trump tax cuts are scheduled to expire in 2025. This creates a unique opportunity for tax planning, but the window is closing.

‍

A recent B.O.S.S. Retirement client saved over $1.1 million in taxes through proper RMD planning and Roth conversions. While your numbers might be different, the principles remain the same.
