Rose Conversion Timing: Should You Convert Early in the Year? The end? Or, spread them out?

Roth conversions are one of the most effective planning strategies for managing taxes throughout your life. If used correctly, they can reduce future tax risk, increase flexibility in retirement, and help smooth income through different stages of life.

Once you determine that a Roth conversion may be appropriate for your situation, the next question is almost always about timing. Should the switch happen early in the year, later in the year, or over time? Below, we'll break down the pros and cons of each approach to help you make more informed planning decisions.

Was Rose's transition at the beginning of the year the right move?

Making a Roth conversion at the beginning of the year can be tempting, especially for those who value decisiveness or who anticipate a relatively low-income year. There are real benefits to taking action early, but there are also trade-offs worth careful consideration.

Pros: More time to realize potential tax-free growth

Assets converted early in the year have more time to grow within the Roth account. If the market performs well, growth occurs in tax-free accounts rather than tax-deferred accounts, which can amplify the long-term benefits of the conversion.

This is especially important from an asset location perspective. You can choose to invest more aggressively (for example: stocks) in a Roth account while holding more conservative assets in a tax-deferred account. Because qualified Roth withdrawals are never taxed and these accounts are not subject to required minimum distributions (RMDs), high-growth assets can compound over longer periods of time without tax drag or forced withdrawals.

That said, this benefit is not guaranteed. This depends on how the market actually performs and how the converted assets are invested. If markets decline or returns are similar across accounts, the advantages of switching earlier in the year may be limited or may not be realized at all.

Advantages: Simple and powerful

A Rose shift at the beginning of the year allows you to make a clear decision and move forward. If your income is stable and predictable, it can feel more efficient to switch sooner rather than later, rather than putting off the decision for an entire year. Generally speaking, tackling a conversion before a year filled with other tax planning, investment decisions, and life can make the process feel more manageable and intentional.

This approach also works well in years when income is significantly lower than normal, such as after retirement but before other income sources like Social Security kick in.

Disadvantages: Uncertainty about income at the beginning of the year

At the beginning of the year, you're probably still estimating your total revenue. Bonuses, consulting income, dividends, capital gains or unexpected events could all increase your taxable income later in the year.

What initially seemed like a reasonable early switch could have knock-on effects if revenue ends up being higher than expected. It could push your ordinary income into a higher tax bracket, convert 0% long-term capital gains to 15%, reduce or eliminate ACA premium subsidies, or trigger higher Medicare premiums (IRMAA) after two years.

Once the conversion is complete, adjustments cannot be made retroactively. This means that early decisions made with incomplete information can lock in the very outcomes you specifically want to avoid.

Disadvantages: Less flexibility if markets change within a year

When you make the switch earlier in the year, you're making the decision before you know how the market will perform during the rest of the year. If the market subsequently drops, you may want to wait and switch at a lower price, but once the switch is complete, it cannot be changed.

Waiting until later in the year preserves flexibility. You can see how the market is actually performing and decide whether to convert the same amount, more, or less based on what happens rather than what you expected.

That doesn't mean the early shift was wrong. It simply means that they trade flexibility for decisiveness, which may or may not fit into your preferred plan.

Should you wait until later this year to switch?

Just as there are reasons to switch early, there are also compelling reasons to wait. Year-end Roth conversions tend to appeal to people who value accuracy and like to make decisions with as much information as possible.

Advantages: Get a clearer picture of your income throughout the year

By later in the year, you'll usually have a clearer idea of ​​how much you're actually earning. Salaries, bonuses, dividends, interest, capital gains and other taxable items are no longer estimates but known figures.

This clarity reduces reliance on assumptions and guesswork. Instead of planning around this year’s predictions, you’re making decisions based on what actually happens.

For you, this can significantly reduce the unexpected risk associated with income fluctuations, year-end capital gains distributions and other taxable income events.

Pros: Better control over tax brackets and income thresholds

Once you know your income for the entire year, you can more accurately determine the size of your Roth conversion. Wait until later in the year and you'll be able to make “just enough” conversions to meet your desired tax bracket without inadvertently spilling into the next tax bracket.

This precision is particularly useful when administering income-based thresholds such as Medicare IRMAA levels. Since these thresholds are determined by gross annual revenue, having complete information allows you to perform conversions with purpose rather than caution.

For many, this ability to fine-tune results is the main appeal of the year-end switch.

Cons: Year-end decision-making pressure

Waiting until the end of the year compresses decision-making into a short period of time. It can be stressful if conversion is viewed as a last-minute task along with other end-of-year planning activities.

End-of-year transitions work best if they are intentional and planned rather than rushed. If you like to space out decisions over time, this extra pressure may feel like a meaningful disadvantage.

Disadvantages: Risk of postponing decision entirely

For some, waiting until later in the year increases the risk that the switch will be delayed or not happen at all. As the year fills up with other priorities, even well-intentioned plans can be put on hold.

This is not a tax issue or a market issue. This is an implementation issue. Life tends to get busier later in the year, with holidays, travel, work deadlines and end-of-year plans all vying for attention. What started out as a “we'll do this in December” plan could quietly turn into no shift at all.

In this case, taking action early, even imperfectly, may be better than waiting for the “perfect” moment that never comes.

Full Year Split or Installment Roth Conversion

Rose's transformation doesn't have to happen all at once in any given year. You might also consider a staged approach, spreading conversions throughout the year.

This is conceptually similar to dollar-cost averaging in investing. Instead of committing everything at one point in time, you spread out the decision-making, which helps take the pressure off of getting the timing right.

Pros: Flexibility, no need to commit to everything at once

A phased approach allows you to convert some of your plan amounts earlier in the year and leave room for adjustments later. This flexibility allows you to react as revenue and market conditions become clearer, rather than committing to everything at one point in time.

If the market goes up, some assets are already on the Roth. If the market falls, later conversions may be at a lower price. This approach doesn't eliminate uncertainty, but it diffuses it, which you may find more comfortable than making one big decision all at once.

The staged approach is not about predicting the market but structuring decisions so no single choice has all the meaning.

Cons: More moving parts to manage

However, splitting conversions throughout the year requires more tracking and follow-up.

You'll want to keep a close eye on how much has been converted, how much room is left in your target tax bracket, and whether any new income changes the math along the way. This approach also creates more decision points. As the year unfolds, instead of making a clear choice, you revisit the decision multiple times, which can add to the mental load.

If you prefer simplicity to continuous adjustments, this added complexity may feel more tiring rather than empowering.

Other considerations: Coordinating taxes

Multiple Roth conversions throughout the year can also add complexity to how and when taxes are paid.

It is often recommended to use cash from an outside retirement account to pay the conversion tax, rather than withholding the tax directly from the converted amount, allowing more of the money to grow inside the Roth. As conversions spread throughout the year, you may need to think more carefully about cash flow, withholding adjustments or estimated tax payments to stay on track and avoid surprises. For some, this coordination feels like a separate project.

If managing your taxes feels like a hassle, one well-planned conversion may be easier to execute than several smaller conversions, even if it offers less flexibility.

How to model Roth conversion timing in Boldin Planner

If you're not sure which timing method works best for you, you can test different strategies directly in the Boldin Planner. Modeling removes the guesswork and replaces it with actual numbers based on your plans.

To model a Roth conversion in your plan, go to My Plans > Fund Flow > Transfers and add a new transfer. Set up future transfers from one of your tax-deferred accounts to a Roth account. If you don't already have a Roth IRA in your plan, you can simply add a Roth IRA with a $0 balance.

From there, you can select the month you wish to convert. For example, you could select January or February for beginning-of-year conversions, or November or December if you're modeling end-of-year conversions. You can also model multiple Roth conversions throughout the year rather than committing to a single conversion date.

What's the best time to convert Rose? Focus on the plan, not the calendar

There is no universally correct month to perform a Roth conversion.

Whether you make the switch early in the year, later in the year, or in stages throughout the year, the key is to make the decision consciously as part of your overall financial planning. When conversions are planned along with your income, taxes, and long-term goals, small timing differences are often far less important than you think.

The right Roth conversion method can help you stay confident, informed, and consistent with your plan year after year.
