The Retirement Planning Decisions That Have Expiration Dates

The first few years of retirement often provide more planning flexibility than people realize. With work income reduced or gone, Social Security potentially still a few years away, and required minimum distributions further in the future, retirees may have considerable control over where their spending comes from and how much taxable income they recognize along the way.

That flexibility changes as retirement progresses. Social Security benefits stop increasing due to delayed retirement credits at age 70, Medicare introduces enrollment decisions and a connection between income and premiums, and required minimum distributions eventually force money out of certain retirement accounts, whether it is needed for spending or not. Decisions about Roth conversions, investment gains, and portfolio withdrawals are happening alongside those changes, which means a choice made in one area can alter the options available in another.

Although these milestones arrive at different ages and are often treated as separate planning issues, they are closely connected. Delaying Social Security can require larger portfolio withdrawals for a period of time while also creating years when taxable income may be easier to manage. A Roth conversion during those years can reduce the balance that will eventually be subject to required distributions, although the additional income may increase Medicare premiums in the nearer term. As Social Security begins and required distributions eventually follow, retirees may have less control over how much taxable income they recognize from year to year.

This makes the years when nothing is forcing you to act particularly valuable. Having several ways to fund spending and greater control over taxable income can create planning opportunities that are easy to overlook precisely because there is no immediate deadline demanding attention. By the time Social Security, Medicare, and required distributions are all part of the picture, some of those choices may still exist, but the range of options can be considerably narrower than it was at the beginning of retirement.

Retirement Can Create a Tax Planning Window

The transition from working to retirement can create a period when taxable income looks very different from what it did during the working years. A household that spent decades earning salaries may suddenly have little or no wage income, even though its lifestyle and spending have not changed very much. If Social Security is also being delayed, spending may temporarily come from cash, taxable investments, retirement accounts, or some combination of the three.

Lower-income years can provide an opportunity to recognize income more deliberately, including through Roth conversions. Converting part of a traditional IRA to a Roth IRA generally creates taxable income in the year of the conversion, but it also reduces the amount remaining in the traditional account that may eventually produce required distributions and taxable income later in retirement.

Deciding how much to convert involves more than comparing today's tax bill with a future one. The additional income can affect Medicare premiums, capital gains, the taxation of Social Security benefits once they begin, and other parts of the tax return. Converting too much can create costs that outweigh the longer-term benefit, while consistently avoiding conversions because they increase current taxes can leave a larger traditional retirement account producing taxable income later.

There may be several years when income can be managed with this degree of flexibility, but the available room changes as other sources of income begin. Social Security and pension income can begin changing the income picture before required distributions eventually add another source of income that is no longer optional. Roth conversions may still make sense after that point, but they are being considered alongside income that the retiree has much less ability to control.

Delaying Social Security Changes More Than Social Security

Social Security benefits can generally begin as early as age 62, while delaying beyond full retirement age increases the monthly benefit until age 70. That decision is often evaluated by comparing the income available from claiming earlier with the larger benefit available from waiting, but the years in between can also influence the rest of the retirement plan.

Someone who delays Social Security still needs to fund spending during those years, which may mean drawing from taxable savings, taking distributions from a traditional IRA, converting some IRA assets to a Roth, or using a combination of those sources. Drawing more heavily from the portfolio can reduce the assets available later, while delaying Social Security can provide a larger source of reliable income for the rest of retirement. How those withdrawals are structured can also affect the amount of taxable income recognized along the way.

For retirees who have stopped working, delaying Social Security may also extend the period when taxable income is easier to manage. Once benefits begin, a portion may be taxable depending on the household’s other income, changing the tax picture that existed during the years when spending was funded primarily from the portfolio.

Delayed retirement credits stop increasing the Social Security retirement benefit at age 70, so the value of waiting changes once that age is reached. By then, the retiree may also be several years into Medicare and getting closer to required distributions, making the decisions surrounding Social Security part of a broader transition from the more flexible years at the beginning of retirement to a period when more sources of income are already in place.

Medicare Adds Another Layer to the Tax Decision

Medicare becomes part of the picture around age 65, whether or not Social Security has started. Enrollment depends in part on the coverage someone has at the time, which is especially important for people who continue working or remain covered by an employer plan after becoming eligible for Medicare.

Once enrolled, Medicare creates another connection between retirement income and taxes because higher income can result in IRMAA surcharges on Part B and Part D premiums. Those surcharges are generally based on income reported on an earlier tax return, which means a decision to recognize additional income can affect Medicare costs later.

A Roth conversion or realizing substantial investment gains during those lower-income years can have consequences beyond the tax return. A larger conversion may increase future Medicare premiums, reduce the amount left in a traditional IRA, and potentially lower required distributions later. Realizing investment gains can have a similar effect on Medicare premiums, even when doing so makes sense as part of the investment or tax strategy.

Higher Medicare premiums do not necessarily mean the original decision was a mistake. Paying an IRMAA surcharge for a period of time may be reasonable if recognizing income today improves the household’s longer-term tax position, just as avoiding the surcharge may make sense when the expected benefit of recognizing additional income is relatively small. Looking at Medicare costs alongside current and future taxes, portfolio withdrawals, and required future distributions provides a clearer view of the trade-off than focusing on the surcharge alone.

Required Distributions Reduce Some of Your Flexibility

Before required minimum distributions begin, retirees generally have considerable control over whether they take money from a traditional IRA in a particular year. Depending on their spending needs and tax situation, they may leave the account alone, take distributions for spending, convert some of the balance to a Roth, or combine those approaches.

RMDs reduce that flexibility because a required amount must be distributed each year whether the money is needed for spending or not. The distribution generally becomes part of the year’s taxable income, and the RMD must be satisfied before additional IRA assets can be converted to a Roth.

For someone with a large balance in traditional retirement accounts, the years before RMDs begin can provide an opportunity to recognize some income voluntarily rather than waiting until distributions are required. Paying tax earlier can feel counterintuitive when deferring it remains an option, but the money left in the traditional IRA may continue to grow and eventually produce larger required distributions.

Those future distributions may arrive when Social Security, pension income, dividends, interest, and other sources of taxable income are already flowing into the household. A retiree who had considerable control over taxable income during the first years after leaving work may have much less flexibility later, even if spending has not increased.

How much of a traditional IRA to draw down or convert before RMDs begin depends on the household’s broader tax picture and expected income over retirement. For some retirees, continued tax deferral will still make sense, while others may benefit from recognizing more income during the years when the amount and timing of those distributions remain largely within their control.

New Planning Opportunities Can Open Along the Way

Some planning opportunities become available later in retirement. For people who are already giving to charity, qualified charitable distributions (QCDs) can provide another way to fund those gifts beginning at age 70½. An IRA owner can make qualifying charitable gifts directly from an IRA, and after RMDs begin, those distributions can count toward the required amount when the applicable rules are met.

That can change how charitable giving fits into the retirement income and tax plan, particularly once distributions from traditional retirement accounts are required. As retirement progresses, planning often involves adapting to this combination of new opportunities and fewer choices rather than continuing with the same strategies that worked at the beginning.

Each Decision Changes What Comes Next

A retirement plan can look very different depending on the order in which these decisions unfold. Someone who claims Social Security early may need less from the portfolio during the first several years of retirement, but will also receive a smaller monthly benefit and may have less room to recognize other taxable income. Delaying Social Security can require more portfolio withdrawals initially while preserving a period when income can be managed more deliberately and allowing the eventual benefit to continue growing.

Roth conversions during those years can reduce the traditional IRA balance that will eventually produce required distributions, although the additional income may also increase Medicare premiums in the nearer term. Once RMDs begin, the income from those accounts becomes less discretionary and can affect taxes, Medicare costs, and even how charitable giving is funded.

Focusing too narrowly on any one of these decisions can produce a result that looks attractive today while creating less flexibility later. Keeping this year’s tax bill low may mean carrying a larger traditional IRA balance into the RMD years, while avoiding higher Medicare premiums may require passing on a Roth conversion that could improve the longer-term tax picture. Claiming Social Security earlier can reduce the amount that needs to come from the portfolio today, but it also means accepting a smaller source of reliable income for the rest of retirement.

Different households will make different choices among those tradeoffs, but each decision changes the starting point for the ones that follow. A choice that lowers taxes, reduces portfolio withdrawals, or avoids higher Medicare premiums today may also change the income and planning options available several years from now.

More Choices Earlier Does Not Mean More Action Is Always Better

Having a planning opportunity does not mean it needs to be used. Someone with modest traditional retirement account balances may have little reason to be concerned about future RMDs, while a Roth conversion may not be attractive when the current tax cost is weighed against the expected benefit later. Delaying Social Security will make sense for some households and not for others, depending on the rest of the retirement plan.

Choosing not to pursue an opportunity after evaluating it is very different from discovering years later that it is no longer available. Retirement may last several decades, but some of the decisions that shape those decades are concentrated in much shorter periods, when retirees have more control over their income, taxes, and sources of spending than they may later.

Good retirement planning looks beyond what needs to happen this year to what will change in the years ahead. Some opportunities will remain, others will become less attractive, and a few will disappear altogether. Decisions made during the more flexible years can shape taxes, income, and spending much later in retirement, which is why those years deserve attention while the choices are still yours to make.
