Top 5 Retiree Financial Mistakes in Arizona (And How to Avoid Them)

Retirement Planning

February 13, 2026

More and more people heading into retirement are packing their bags for Arizona, and for good reason. The state consistently ranks among the top three retirement destinations in the country, with Scottsdale and surrounding communities earning national recognition as some of the best places to retire in the U.S.

With world-class golf courses, abundant hiking trails, top restaurants, and endless sunny days, it’s easy to see the appeal.

But while Arizona is undeniably attractive, there are important financial considerations that often get overlooked, especially when it comes to taxes, healthcare costs, and the realities of triple-digit summers.

Whether you already call Arizona home or are considering making the move, here are the five most common financial mistakes retirees make and how to avoid them.

Quick Summary: Top Retirement Financial Risks in Arizona

Risk Area	Why It Matters	What to Watch For
Taxes & Residency	Arizona taxes retirement account withdrawals	2.5% flat income tax; 7+ months to establish residency
Summer Costs	Extreme heat drives expenses higher	Electric bills, pool maintenance, landscaping
Healthcare	Above-average healthcare costs	Long-term care costs, specialist wait times
Withdrawal Strategy	Poor sequencing increases taxes	Social Security timing, capital gains
Plan Reviews	Life and tax laws change over time	Missed opportunities, outdated strategies

#1 Lack of Clarity on Arizona’s Tax and Residency Rules

Arizona is considered retiree-friendly for good reason:

No tax on Social Security benefits
No estate tax
No inheritance tax

However, distributions from retirement accounts such as 401(k)s and IRAs are taxable.

As of 2025, Arizona has a flat 2.5% state income tax across all income levels.

If you want Arizona to be your primary residence for tax purposes, you generally need to spend seven months or more per calendar year in the state.

Other Important Tax Considerations

Property taxes are lower than many states
Seniors may qualify for property tax relief programs
Homeowner’s insurance is often below the national average
Sales tax averages around 8.5%, which is higher than many retirees expect

Arizona can absolutely be tax-efficient — but only with intentional planning.

#2 Underestimating Arizona’s Heat and Its Hidden Costs

Arizona summers are no joke.

Recent years have seen 100+ days above 100 degrees. While sunshine is a major draw, many retirees underestimate how the heat impacts lifestyle and expenses.

Financial Impact of Arizona Summers

Electric bills spike for 3–5 months
Higher gasoline usage due to AC
Pool and landscaping maintenance can exceed $3,000+ annually before repairs
Increased indoor entertainment and travel costs

The lifestyle adjustment is real, and so is the budget impact.

#3 Overlooking Healthcare Affordability and Accessibility

Arizona has an extensive healthcare network, including respected institutions like Mayo Clinic.

But access does not always mean affordability.

Healthcare Considerations in Arizona

Healthcare costs are above the national average
Some popular retirement areas in the state may require 30–45 minute travel for care
Specialty care wait times can be long
Long-term care costs exceed national averages

On the positive side, Arizona’s dry climate can benefit those with arthritis, asthma, or allergies. However, the Phoenix-Mesa area does rank higher than many metro areas for air pollution — another factor to consider.

Healthcare planning should include:

Medicare strategy
Supplemental coverage
Long-term care funding
Emergency travel logistics

#4 Skipping a Solid Withdrawal and Distribution Strategy

This is one of the most common and costly retirement mistakes.

A well-designed withdrawal strategy coordinates:

Income needs
Tax efficiency
Investment risk
Social Security timing

Without a clear strategy:

You could accidentally push yourself into a higher tax bracket
Trigger avoidable capital gains
Miss Roth conversion opportunities
Reduce lifetime Social Security benefits

For example, delaying Social Security while drawing from tax-deferred accounts can sometimes reduce lifetime taxes and increase guaranteed income — but this depends entirely on your situation.

Distribution strategy isn’t something to “wing.” It should evolve annually.

#5 Forgetting to Have Your Plan Reviewed Regularly

Arizona may be affordable today — but inflation, tax laws, healthcare costs, and personal circumstances change.

Common review triggers include:

Market volatility
Required Minimum Distribution (RMD) age
Moving from part-time work to full retirement
Death of a spouse
Changes in tax law

An outdated retirement plan can quietly create future shortfalls.

Even a well-built plan needs maintenance.
