RMDs: What They Are, Why They Matter & How to Use Them to Your Advantage
Presented by Retirement GPS: Navigated by Zynergy
What Exactly Are RMDs?
RMDs are the government’s way of ensuring retirement dollars—those dollars you avoided tax on for decades—finally get taxed.
They apply to:
- Traditional IRAs
- 401(k)s
- 403(b)s
- 457 plans
- SEP & SIMPLE IRAs
- Inherited IRAs (with special rules)
Current law requires RMDs to begin at:
- Age 73 (today)
- Age 75 (for those who reach 75 after 2033)
How RMDs Are Calculated
RMDs are calculated using:
- Your retirement account balance on December 31 of the prior year
- Your IRS life expectancy factor
For example:
At age 73, the distribution factor translates to about 3.77%.
At age 90, it’s closer to 8.2%.
This means RMDs naturally increase with age—not only because life expectancy shortens, but because your account may continue growing even as you draw from it.
Why RMDs Can Become a Problem
If RMDs push your income higher than expected, several areas are affected:
- Federal tax brackets
Higher taxable income can trigger 22%, 24%, 32%, or 35% brackets unexpectedly.
- Medicare IRMAA
Income above certain thresholds increases your monthly Medicare premiums—sometimes dramatically.
- Social Security taxation
Social Security is taxable up to 85%, and higher RMD income can automatically bump you into that range.
In other words:
When your RMDs grow, you lose control of your tax bracket.
Smart Strategies to Manage Your RMDs
Here are several ways to turn RMDs from a tax burden into a planning opportunity:
- Use RMDs to Fund Your Lifestyle
- If you need the income already, your RMD simply becomes part of your cash-flow plan. There’s no extra work—just alignment.
- Consider Qualified Charitable Distributions (QCDs)
- If you’re planning on giving to charity, doing so directly from your IRA means:
- It satisfies your RMD
- It avoids income tax
- It does not increase Medicare or Social Security taxation
- QCDs are one of the most powerful tax breaks retirees have.
- If you’re planning on giving to charity, doing so directly from your IRA means:
- Take Advantage of Tax Loss Harvesting
- In market downturns, losses in taxable accounts may offset a portion of the tax impact from RMDs.
- Automate Your RMDs
- Missing an RMD can carry a penalty of up to 25% (reduced to 10% if corrected quickly).
- Automation ensures you never miss a deadline—especially as account structures become more complex.
- Plan Ahead with Roth Conversions
- This is the single best long-term RMD strategy.
By gradually converting IRA funds into Roth—even in your 60s before RMD age—you:
- Reduce future RMDs
- Create tax-free retirement income
- Gain control over tax brackets later in life
- Avoid IRMAA spikes
- Build tax diversification
And Roth IRAs have no RMDs at all.
Think of Roth as the treasure chest you get to keep 100% of—no tax bite from the IRS later on.
Common Mistakes to Avoid
- Missing your first RMD deadline
- Taking two RMDs in one year accidentally
- Failing to draw RMDs from every 401(k)
- Assuming Roth IRAs have RMDs (they don’t!)
- Not understanding how RMDs affect IRMAA and Social Security taxation
- Ignoring inherited IRA rules
- Thinking “I’ll never have too much money” and not planning ahead
RMD mistakes are almost always avoidable with awareness and planning.
