The Eight Financial Mistakes People Make in the Five Years Before Retirement

The risks of the final five years are mostly outside your control. The mistakes are not. Here are the eight that do the most damage, the one habit underneath all of them, and what a written plan does about each.

The accumulation years ran on one instruction. The distribution years run on a dozen, and they interact.

The biggest financial mistakes in the five years before retirement are retiring without a written income plan, carrying an allocation built for accumulation into distribution, letting required minimum distributions dictate tax brackets instead of planning around them, bringing high-interest debt into retirement, claiming Social Security by default rather than by strategy, underestimating healthcare and care costs, ignoring inflation across a long retirement, and leaving employer benefits and catch-up contributions unused; all eight share one cause, which is treating decisions that interact as if they were separate.

Our article on the six risks of retiring in the next five years covers what can go wrong that you do not control: markets, inflation, health, policy. This one covers the other side. In the second half, money becomes more complicated at exactly the time you want life to become less complicated, and most of the avoidable damage in the final working years comes from a small set of decisions made by default. Retirement also arrives earlier than planned for many people, through a health change, a family need, or an employer's decision, so the five-year window is often shorter than it looks.

The shift underneath all eight

For decades the instruction was simple: earn, save, grow. The distribution years reverse it. The portfolio has to produce income, survive a bad start, and stay tax-aware while it does, and the decisions, when to claim, which account to draw, whether to convert, how to cover care, all touch each other. Each mistake below is a failure to coordinate decisions that interact.

1. Retiring without a written income plan

A balance and a withdrawal rate are not a plan. A plan says where each year's spending comes from, in what order, what adjusts if the first years are poor, and what the Social Security and pension decisions do to the rest. Our article on why the answer is a plan, not a percentage explains what the document contains.

2. Carrying an accumulation allocation into distribution

Too aggressive, and an early decline forces sales at the bottom while withdrawals continue. Too conservative, and the portfolio cannot keep pace with thirty years of rising costs. The fix is segmentation: near-term spending in stable assets, later years in growth, so a bad first stretch does not force the wrong sale.

3. Reactive tax planning

Taking withdrawals as needed and converting nothing leaves a large pre-tax balance for the years when required minimum distributions set the amount and the bracket. The years between leaving work and the start of RMDs and Social Security are usually the lowest-income years a retiree will have; conversions, gain harvesting, and withdrawal sequencing done then are the difference between a tax plan and a tax bill. Our article on the seven tax mitigation strategies covers each lever.

4. Bringing high-interest debt into retirement

A payment that was manageable on a salary has to be covered by the portfolio once the paycheck stops, which raises the withdrawal the plan must support and the tax on it. Debt with a rate above what the portfolio is reasonably expected to earn is usually worth clearing before the date; low-rate, deductible debt is a case-by-case decision, made inside the cash flow projection rather than by instinct.

5. Claiming Social Security by default

Claiming at the earliest age because it is available permanently reduces the benefit and, for a married couple, the survivor benefit. Delaying raises both. The right date depends on health, other income, how the claiming date stacks against RMDs, and what the surviving spouse will need. It is a modeled decision, and West Virginia residents have a state tax change to fold in; our article on the 2026 exemption covers it.

6. Underestimating healthcare and care costs

Medicare premiums are set by income from two years earlier, Medicare does not cover most long-term care, and the long-term care decision has to be made while coverage is still underwritable. A plan without a healthcare line and a care decision has left out two of the largest numbers in it.

7. Ignoring inflation

An income that is comfortable in year one buys noticeably less by year fifteen, and the categories retirees spend on have historically risen faster than the headline rate. The response is a segmented plan with growth assets for later years, a flexible spending rule, and a Social Security decision that weighs the inflation-adjusted value of delay.

8. Leaving employer benefits and catch-up contributions unused

The final working years allow larger retirement-plan contributions for those over fifty, and employers often provide benefits, matching, health savings accounts, retiree medical, stock plans, that are lost or mispriced at separation. The plan should inventory every benefit and decide, before the exit date, what to use, roll, or leave.

None of these mistakes is a lack of effort. Each is a decision made alone that should have been made with the others in view.

How Beacon addresses them together

At Beacon Wealth Management, every client follows the same four-step Guided Journey, Understanding, Identification, Recommendation, and Actions, which produces a written Financial Summit Map coordinating six areas: wealth planning, retirement income, investment management, tax mitigation, long-term care and life insurance, and legacy and estate planning. The Identification step is where these eight surface, because they are measured against the same projection.

Close to home: Clarksburg

Clarksburg, the Harrison County seat, is five minutes from our Bridgeport office and home to one of the largest federal workforces in the state at the FBI's Criminal Justice Information Services Division. Federal employees approaching retirement face a version of every mistake on this list at once: a FERS pension election, a Thrift Savings Plan withdrawal strategy, a Social Security decision that interacts with both, and health benefits that carry into retirement only if certain conditions are met before the date. Founder John T. Halterman holds the Chartered Federal Employee Benefits Consultant designation for exactly this work, and we meet with Clarksburg families, federal and otherwise, in person.

What to do now

If you are within five years: get the written plan built, run the Social Security and conversion decisions through it, make the care decision while coverage is available, and inventory the employer benefits before the exit date.

— Common Questions —

Mistakes before retirement

What is the biggest financial mistake before retirement?
Retiring without a written income plan. Every other mistake on the list, from default Social Security claiming to reactive tax planning, follows from decisions made one at a time instead of inside a plan that shows how they interact.
When should I claim Social Security?
It depends on health, other income, how the claiming date stacks against required minimum distributions, and what a surviving spouse will need. Claiming at the earliest age permanently reduces the benefit and the survivor benefit; delaying raises both. The date should be modeled inside the income plan rather than chosen by default.
Should I do a Roth conversion before retirement?
Possibly. The years between leaving work and the start of required minimum distributions and Social Security are usually the lowest-income years a retiree will have, which is when conversions do the most. The size and timing depend on brackets, Medicare surcharge thresholds, and the inheritance effect, so the decision belongs in a multi-year projection.
What happens if I miss a required minimum distribution?
A penalty applies to the amount not taken, reduced if the shortfall is corrected promptly. The larger cost is usually the tax plan that was never built: a large pre-tax balance reaching RMD age means the government sets the withdrawal and the bracket.
Should I pay off debt before retiring?
Debt with a rate above what the portfolio is reasonably expected to earn is usually worth clearing before the date, because the payment otherwise has to be funded by taxable withdrawals. Low-rate or deductible debt is a case-by-case decision made inside the cash flow projection.
