For IRA Millionaires who have been thinking about Roth conversions “sometime this year” or “sometime next year,” the strategic frame is often too small. A Roth conversion is not a single afternoon of clicking buttons in December. It is closer to a chess game against the IRS — the outcome depends on where the pieces sit long before the move gets made.
After more than 14 years and studying more than 2,000 real client conversion plans, our team has watched two things play out repeatedly. First, the households that treat conversions as a game with multiple pieces and multiple moves produce dramatically better lifetime outcomes than the households that treat conversions as a single transaction. Second, waiting — even by a single year — costs real money that never comes back. This article walks through the five pieces that make up a well-built conversion plan, why each one has its own lead time, and what our research shows waiting actually costs in dollars.
The Rook: Your CPA (The Tax-Season Constraint)
The rook is a powerful piece — it can move as far as it wants in a single move once the board is open. Early in the game, though, it sits stuck behind the pawns, not much use until the surrounding pieces have cleared out of the way.
Your CPA is your rook. From February through April, they are buried in filings, deadlines, extensions, and client returns. If you want to coordinate estimated payments, withholding, and conversion timing properly, you need that conversation done well before they get swamped — or well after tax season ends. Miss both windows entirely and the coordination conversation gets pushed into next year.
Move Your Pieces Into Place
Our team has built more than 2,400 multi-year conversion plans, and every strong plan is the result of five pieces coordinated well in advance. Find out what waiting is costing your specific household — with no product pitch and no obligation.
The Bishop: Your Investment Advisor (The Diagonal Lines)
The bishop moves diagonally across the board. It spots lines that aren’t obvious if you’re only looking straight ahead — the paths that cut across the position.
Your investment advisor is the bishop. Most households ask how much to convert. The bishop asks what to convert. Which specific holdings are down at the moment. Which have the strongest recovery potential. Which fit the household’s broader portfolio structure. Those are the diagonal questions — the ones a simple “convert to the top of the bracket” calculation never reaches — and they require time to work through.
Identifying the right assets takes real evaluation across the portfolio. That work rarely produces its best answer when compressed into the last three weeks of December. By then the cake is baked, and much of the year’s most useful information about which positions to convert is already locked in.
The Knight: Your Estate Attorney (The Unexpected Move)
The knight is the piece most people ignore until it changes the entire game. It does not move in straight lines or diagonals — it jumps. It attacks pieces the opponent didn’t see coming.
When you convert dollars from a traditional IRA to a Roth IRA, you’re not just moving money between two retirement accounts. You’re changing the tax character of those dollars from pre-tax to post-tax. That change can jump into places you didn’t expect. It can affect how the account passes to heirs. It can affect the interaction between the Roth conversion and existing trust structures. It can affect whether the estate documents on file still do what the household thinks they do.
Your estate attorney is the knight. Before any major conversion sequence starts, a quick review — often a short conversation — is what keeps the strategy from inadvertently breaking something else in the plan.
The King: Your Spouse (The Piece the Whole Strategy Protects)
The king is the piece the entire strategy is built around protecting. He can only move one square at a time, so when he gets cornered, there is not much he can do. You do not win by ignoring the king or leaving him exposed. You definitely do not win by making bold moves on one side of the board while the king is vulnerable on the other side.
Your spouse is the king. Roth conversion planning affects both spouses’ retirements, and it affects what happens to the surviving spouse after the first passes — including the survivor’s exposure to single-filer brackets, IRMAA thresholds, and forced RMD income. A strategy can look excellent on paper and still fail if the person most affected by the long-term consequences isn’t fully part of the decision.
Our team has watched more plans stall because a spouse wasn’t fully in the room than for almost any other reason. Getting both spouses aligned — not just informed, but actively part of the conversation — is what allows the plan to actually execute confidently.
The Queen: Timing (Your Most Flexible Piece)
The queen is the most flexible piece on the board. She can move in multiple directions and create major advantage — but only when she has space to move. Rush her into a cramped position and the opponent takes her out before the advantage materializes.
Timing is the queen. The best conversion opportunity in any given year rarely arrives in December. It often arrives when markets are temporarily down, when the household’s projected income is lower than expected, or when a tax projection reveals unused room in the current bracket. Recognizing those moments requires a full year to monitor them and the flexibility to act when they appear.
Our team’s research is unambiguous on this point: December is the worst time of year to convert once all the variables are weighted together. The households that produce the best conversion outcomes are the ones whose queen has been positioned for tactical moves all year long. For more on why annual timing matters, see our team’s analysis of the best time of year for a Roth IRA conversion and navigating Roth conversions in a volatile market.
The Real Cost of Waiting: The Math on 2,000+ Plans
Here’s what our team’s research across more than 2,000 real client conversion plans actually shows. The numbers below come from a sample plan our team modeled. Specific dollar figures will differ from household to household — IRA balance, age, income, and tax-law context all vary. The direction is consistent across thousands of cases.
Consider a household whose well-executed Roth conversion strategy, started now with a full planning year and all five pieces in position, produces approximately $1.8 million in projected lifetime tax savings. Higher-balance households in this same modeling range can reach $2 to $3 million. That’s the baseline — the dollar value of playing chess strategically.
Now consider what waiting looks like.
| Decision | Projected Lifetime Tax Savings | Cost of Delay |
|---|---|---|
| Start now, full planning year | ~$1.8M | — |
| Wait one year | ~$1,768,600 | ~$66,400 |
| Wait five years | ~$1.44M | ~$357,000 |
$66,400 of lifetime tax benefit, gone, because the household waited one tax year. Not because the plan got worse. Not because anything went wrong. Simply because the window was one year narrower and the queen had less room to move.
$357,000 of lifetime tax benefit, gone, after five years of delay. Five years of “I’ll get to it,” “I’ll wait until markets settle,” or “I’ll do it once I’m in a lower tax bracket.” That money doesn’t disappear. It stays with the IRS and comes directly out of what the household, the surviving spouse, and eventually the heirs would have kept.
Alongside the delay math, our team’s research on those same plans shows that a fully coordinated conversion — proper CPA timing, strategic asset selection, in-year market awareness — adds as much as $30,000 of value for every $1 million converted compared to plans compressed into the last few weeks of the year. That value isn’t created by a better plan on paper. It’s created by every piece having the time it needs to move.

Why Compounding Now Works Against You
Most IRA Millionaires built their wealth by understanding compounding. Every year the IRA grew, the next year’s growth happened on a larger balance, and over thirty or forty years that produced real wealth.
That same force is now working against the household. Every dollar sitting in a traditional IRA will eventually be taxed at ordinary income rates — that was the agreement made when the contribution went in. The only remaining questions are when the tax gets paid and on what amount. While the household decides, the account keeps growing. Every dollar of growth is another dollar the IRS has a claim on.
One of our clients put it better than anyone: “It feels good to look at your spreadsheet and say I’ve got all this money. Then you have to stop and say, ‘Wait a minute — that’s not all my money. It’s the government’s money too.'” He’s right. That number on the statement includes a meaningful portion that was never the household’s to spend. The longer it sits in the traditional IRA, the larger the IRS’s share becomes — and the tighter the board gets for every piece the household is trying to move.
Common Mistakes to Avoid
Several errors quietly compound the cost of waiting:
- Treating conversion as a December transaction. A real plan needs a full year of execution runway. The last six weeks aren’t enough to move all five pieces.
- Delaying the CPA conversation until next tax season. The right time to coordinate is now, between filings, while the rook can actually move.
- Postponing the spouse conversation. Plans stall most often because the king isn’t in the room. Getting genuine alignment early is more valuable than perfect math later.
- Confusing “I have a plan” with “I have a result.” The plan in a folder does not reduce taxes. Only execution does.
- Waiting for markets to feel certain. They never feel certain. The queen moves best when the household is ready, not when the headlines feel reassuring. For more on why multi-year sequencing beats single-year decisions, see our team’s analysis of multi-year Roth conversion strategies.

Frequently Asked Questions
Why is waiting a year on a Roth conversion so expensive?
Because a conversion plan is not a single move — it’s a coordinated set of decisions across CPA timing, investment selection, estate coordination, spouse alignment, and market timing. Each of those pieces requires lead time to position properly. Waiting a year doesn’t compress the plan; it compresses the execution window. In one sample plan our team modeled, that compression cost approximately $66,400 in projected lifetime tax savings.
When should I start planning my 2026 Roth conversion?
As early in 2026 as practical. The first quarter is the widest planning window — the rook (CPA) is most accessible before tax season, the queen (timing) has a full year to spot tactical opportunities, and the other pieces have time to position properly. December starts are heavily compressed and consistently produce worse outcomes than plans built in Q1.
Is a “convert to the top of my current bracket” approach enough?
For households with modest IRA balances, sometimes. For IRA Millionaires, rarely. That approach optimizes for this year’s tax bracket, not the household’s lifetime tax bill. Future RMDs sit in much higher brackets for decades, the surviving spouse files single, and the heirs inherit at their highest-earning years. The full chess game — all five pieces — routinely produces materially better lifetime outcomes than any single-year rule of thumb.
What if I’m already in the last quarter of the year?
Do the most urgent things this year and clean up in Q1 of the following year. Q4 conversions are less than optimal, but that isn’t a license to skip the year entirely — waiting produces its own cost. The right move is to complete the highest-value decisions before December 31 and start the following year’s plan much earlier.
What does the “$30,000 per $1 million converted” figure represent?
Across our team’s research on more than 2,000 client conversion plans, conversions executed with a full planning year — proper coordination, the right timing, strategic investment selection — add as much as $30,000 of value for every $1 million converted, compared to plans executed in compressed end-of-year windows. That value isn’t created by a better plan on paper. It’s created by every piece having the time it needs to move.
Why is coordinating with my spouse so critical?
Because the strategy is built around protecting both spouses’ financial futures, including what happens to the surviving spouse. Single-filer brackets and IRMAA thresholds hit at much lower income levels than joint thresholds. A strategy that ignores this — or that only one spouse fully understands — tends to stall in execution and can leave the surviving spouse exposed to exactly the tax problem the conversion was supposed to prevent.
