For many retirees in Sun City and Surprise, retirement has already begun.

The transition from earning a paycheck to drawing from savings is behind them. The focus now is on maintaining income, preserving assets, and avoiding unnecessary mistakes.

And for most, one of the first surprises is this:

Required Minimum Distributions are not optional.

They arrive whether the income is needed or not.

And once they begin, they tend to grow.

A Familiar Situation

Consider Robert and Elaine.

They are both 74, living in Sun City. Their home is paid off. Their lifestyle is steady and predictable.

Their financial picture looks like this:

• $1.9 million in traditional IRAs
• $250,000 in taxable investments
• Social Security covering about $55,000 annually
• No pension

They don’t feel like big spenders. Their annual spending is roughly $90,000.

But their Required Minimum Distributions are already over $70,000—and increasing each year.

Which creates a problem they didn’t expect:

They are being forced to take more income than they actually need.

What RMDs Actually Do

Required Minimum Distributions, or RMDs, are the IRS’s way of collecting deferred taxes.

For decades, retirees contributed to traditional retirement accounts and deferred taxation. RMDs ensure that, eventually, those taxes are paid.

Starting at age 73:

• You must withdraw a calculated portion of your retirement accounts each year
• The percentage increases over time
• The withdrawals are taxed as ordinary income

This is not a one-time event.

It is a permanent shift in how income is generated.

The Income Stacking Problem

What catches many retirees off guard is how RMDs interact with other income sources.

In Robert and Elaine’s case:

• $55,000 from Social Security
• $70,000+ from RMDs

That puts them at $125,000 of income before any additional withdrawals, interest, or capital gains.

The result is what planners often refer to as “income stacking”:

• Higher tax brackets
• Increased taxation of Social Security benefits
• Exposure to Medicare premium surcharges (IRMAA)

None of this is obvious when looking at each piece individually.

It only becomes clear when everything is combined.

Why This Feels Like a Surprise

Most retirees in Sun City and Surprise spent decades focused on saving.

Maximizing contributions. Deferring taxes. Building balances.

Very little attention was given to how that money would eventually come out.

So when RMDs begin, it feels like a loss of control.

Income is no longer:

• flexible
• optional
• or fully aligned with spending needs

It is dictated, in part, by the IRS.

Arizona Helps—But Doesn’t Solve the Problem

Arizona is generally considered tax-friendly for retirees.

• Social Security is not taxed at the state level
• The state income tax rate is relatively low

But RMDs are still subject to:

• federal income tax
• and state income tax

So while the tax burden may be lighter than in higher-tax states, it is still meaningful.

And for many retirees, the issue isn’t the state tax rate.

It’s the total income level created by RMDs.

What Effective RMD Management Actually Looks Like

For retirees already taking RMDs, the goal isn’t to eliminate them.

That’s no longer possible.

The goal is to manage the consequences.

1. Coordinating Withdrawals

RMDs are just one part of the income picture.

Other withdrawals—from taxable accounts or Roth accounts—should be coordinated carefully to avoid pushing income into higher tax brackets unnecessarily.

Taking money “as needed” without coordination often leads to inefficiency.

2. Managing Tax Brackets

Even within the constraints of RMDs, there is often room to manage how additional income is layered on top.

This includes:

• timing capital gains
• controlling additional IRA withdrawals
• evaluating when to realize income versus defer it

Small adjustments can have a measurable impact over time.

3. Using Qualified Charitable Distributions (QCDs)

For retirees who are charitably inclined, Qualified Charitable Distributions can be a useful tool.

They allow:

• direct transfers from an IRA to a qualified charity
• which count toward the RMD
• without being included in taxable income

This can reduce overall tax exposure, particularly for those who do not itemize deductions.

4. Reinvesting Excess Income Intentionally

Many retirees do not need their full RMD for spending.

The default behavior is often to let excess cash accumulate.

A more intentional approach involves:

• reinvesting in taxable accounts
• aligning investments with overall asset allocation
• maintaining liquidity for future needs

RMDs don’t have to disrupt the plan—but they do need to be integrated into it.

What Could Have Been Done Earlier

For many households, the most effective RMD strategy starts before RMDs begin.

That includes:

• gradual Roth conversions in lower-income years
• diversifying tax exposure across account types
• reducing the size of pre-tax balances over time

Once RMDs begin, those options become more limited.

That’s why many retirees feel like they are reacting instead of planning.

Where Retirees in Sun City and Surprise Go Wrong

The most common mistake is treating RMDs as a standalone requirement rather than part of a broader income strategy.

Other issues include:

• Taking additional withdrawals without considering tax impact
• Ignoring how RMDs affect Social Security taxation
• Failing to plan for Medicare premium increases
• Letting excess income sit idle without purpose

None of these decisions seem significant in isolation.

Over time, they add up.

The Bottom Line

Required Minimum Distributions are not a problem to be solved.

They are a condition to be managed.

For retirees in Sun City and Surprise, the focus should not be on avoiding RMDs, but on integrating them into a broader plan that:

• manages taxes
• maintains flexibility
• and supports long-term income needs

Because once RMDs begin, the question is no longer:

"How much should I take?"

It becomes:

"How do I make this work efficiently for the rest of my life?"
