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 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

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.
| Mistake | What it costs | The planning response |
|---|---|---|
| No written income plan | Decisions made by default, one at a time | A segmented plan with a withdrawal sequence and a stress test |
| Accumulation allocation in distribution | Forced sales early, or too little growth later | Segmented allocation by time horizon |
| Reactive tax planning | RMDs set the bracket; conversions never happen | Multi-year projection; conversions in the low-income years |
| Debt into retirement | Higher required withdrawals and tax | Clear high-rate debt before the date; model the rest |
| Default Social Security claiming | Permanently lower benefit and survivor benefit | Claiming date modeled against RMDs and survivor income |
| Healthcare and care costs ignored | Surcharges and an uninsured care need | Dedicated healthcare line; care decision while insurable |
| Inflation ignored | Falling purchasing power across decades | Growth segment; flexible spending rule |
| Employer benefits unused | Lost matching, catch-up room, retiree benefits | Benefit inventory before the exit date |
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.
