The Most Important Years of Retirement Are the First Ones

Most people spend decades planning how to get to retirement.

Far fewer people spend time thinking about what the first few years of retirement will actually look like.

In our experience, those early years matter more than many people realize. Retirement plans rarely fail because of something that happens at age 85. More often, the decisions that shape long-term success are made in the first three to five years after leaving work.

That transition period is when income changes, taxes shift, spending evolves, and daily life looks very different. Those early choices quietly set the foundation for the decades that follow.

Here are five of the most common mistakes we see people make early in retirement — and how thoughtful planning can help avoid them.

1. Spending More in the Early Years Than Expected

One of the biggest surprises in retirement is how spending changes.

Many retirees experience what we sometimes call a “freedom spending” phase. After years of focusing on work and saving, people finally have the time to travel, complete home projects, explore hobbies, and spend more time with family.

There is nothing wrong with this. In many ways, it is exactly what retirement is meant to allow.

The challenge is that these expenses often cluster in the early years of retirement. Travel that was postponed for decades, home improvements delayed during busy working years, and helping adult children financially can all happen at once.

From a planning perspective, spending in the early years matters more than many people realize. Withdrawals made early in retirement have the greatest impact on long-term portfolio sustainability because investments have less time to recover and compound.

The goal isn’t to avoid spending, it’s to pay attention to spending patterns during the first few years and adjust thoughtfully. Thoughtful and proactive planning for increased spending ahead of your retirement for can also help keep you on track.

 

2. Underestimating Healthcare and Future Taxes

Healthcare costs are another area that can surprise retirees.

While Medicare provides important coverage, it does not eliminate healthcare expenses entirely. Premiums, supplemental insurance, prescription coverage, and out-of-pocket costs can represent a meaningful portion of a retiree’s budget. IRMAA surcharges are often a surprise.

For many households, healthcare eventually replaces the mortgage as the largest recurring expense.

Taxes can also change over time. Required minimum distributions from retirement accounts later in life can increase taxable income significantly. Retirees who focus only on minimizing taxes in the early years may inadvertently create larger tax obligations later if tax-deferred accounts continue to grow untouched.

Good retirement tax planning isn’t about minimizing taxes this year; it’s about managing taxes thoughtfully over time.

 

3. Becoming Too Conservative With Investments

When people stop working, it is natural to feel more cautious about market risk. Many retirees respond by shifting large portions of their portfolio into cash or conservative investments.

While the instinct is understandable, retirement portfolios still need to support a time horizon that may last 25–30 years.

The biggest long-term risks in retirement are often inflation and longevity, not short-term market volatility.

Another challenge occurs when retirees experience the first market downturn after leaving work. Without employment income as a safety net, market fluctuations can feel more unsettling. Some people react by moving to cash after markets decline, only to re-enter later once markets recover.

A retirement portfolio isn’t just an investment allocation — it’s part of a long-term withdrawal strategy designed to support income over time.

 

4. Making Social Security Decisions Too Quickly

Social Security is one of the most valuable financial benefits available in retirement: a lifetime, inflation-adjusted income stream.

The age at which someone claims benefits can significantly influence lifetime income, particularly for married couples where the higher earner’s benefit may eventually support a surviving spouse.

Many people claim benefits early for understandable reasons: uncertainty about the future, concern that the system may change, or simply the desire to start receiving benefits after years of paying in.

But this decision is often more impactful than people realize.

In addition, the years between retirement and required minimum distributions often create a window where taxable income is temporarily lower. These years can provide opportunities for thoughtful tax planning that may reduce taxes later in retirement.

Income decisions early in retirement can influence taxes and cash flow for decades.

 

5. Not Planning the Life Transition

One of the most underestimated aspects of retirement has little to do with money.

Work provides structure, purpose, social interaction, and a sense of identity. When that structure disappears, the transition can feel more significant than many people expect.

A common dynamic we see is retiring away from work rather than retiring toward something.

Having a sense of how time will be spent — whether through travel, hobbies, volunteering, or new pursuits — can make the transition much more fulfilling.

Couples also sometimes discover that retirement changes daily routines in ways they hadn’t fully considered. If time permits, consider a dress rehearsal for retirement by taking an extended vacation or sabbatical from work to try on what retirement might feel like. This experience can ease the transition and sharpen your planning. Planning not only the finances of retirement but also the rhythm of daily life can make the adjustment much smoother.

 

The Transition Matters More Than the Destination

Retirement planning often focuses on reaching the finish line: accumulating enough savings to stop working.

However, the reality is that retirement success is often determined by how thoughtfully the transition is managed.

The early years of retirement establish spending habits, shape tax outcomes, influence investment decisions, and define how income will support the decades ahead.

Retirement is not simply about leaving work, rather it is about entering the next stage of life with clarity, flexibility, and confidence.
