I confirmed how one can estimate the impact of Roth conversion and capital features if you get medical insurance from the ACA market within the earlier submit Roth Conversion and Capital Features On ACA Well being Insurance coverage. Some readers expressed curiosity in seeing the identical for retirees on Social Safety and Medicare.
Roth Conversion for Retirees
Whenever you do a Roth conversion, you switch an amount of cash out of your pre-tax account to your Roth account. This makes you pay taxes on the transferred quantity now within the hope of avoiding paying taxes at the next fee sooner or later. It’s a type of prepayment.
As in different conditions of prepayments, typically it is smart to prepay, and typically it doesn’t make sense to prepay. You change to Roth and prepay taxes now if you suppose your tax charges sooner or later can be larger than your tax charges now.
You want to know what tax fee you pay in your Roth conversion with the intention to choose whether or not it is smart to transform. The tax fee you pay in your Roth conversion is determined by how a lot you change. Conversely, if you happen to set a restrict on the tax fee you’re prepared to pay on a Roth conversion, you have to know the way a lot you possibly can convert earlier than you hit that most tax fee.
Case Research Spreadsheet
My favourite instrument for any such planning calculation is the Case Research Spreadsheet created by consumer MDM on the Mr. Cash Mustache discussion board. Utilizing downloaded tax software program additionally works, however tax software program for the present 12 months normally doesn’t come out till November or December and it’s usually incomplete pending updates at that stage. The Case Research Spreadsheet is up to date a lot sooner.
It’s an precise spreadsheet file, not a web based one. You will want Microsoft Excel or suitable software program to open it. As with something downloaded from the web, you’ll have to belief the supply. I had some interplay with the creator over electronic mail. I belief this spreadsheet.
The spreadsheet does numerous issues. It seems overwhelming in case you are solely searching for one characteristic out of many. I’ll present you ways this spreadsheet calculates the impact of Roth conversion when you’re on Social Safety and Medicare. I used model 22.06a launched on November 26, 2022.
Obtain the Spreadsheet
The hyperlink to the newest model of the spreadsheet is within the first submit within the Case Research Spreadsheet updates thread within the Mr. Cash Mustache discussion board. Click on on the hyperlink and select File -> Obtain to avoid wasting the file to your laptop. Make a duplicate of the spreadsheet and solely work with the copy. This fashion you possibly can at all times begin recent from one other copy of the unique spreadsheet to mannequin completely different inputs.

Open the copy in Microsoft Excel or a suitable program. Click on on Allow Modifying within the yellow ribbon you see in Excel.
Situation – Married Submitting Collectively
I’ll use this state of affairs of a married couple as the primary instance.
A retired couple, each age 66, Florida residents, married submitting collectively with no dependents. They dwell on $60,000 of Social Safety advantages, $20,000 of Conventional IRA withdrawals, $5,000 of curiosity earnings, and $10,000 of certified dividends. They don’t have any different earnings or deductions. Each of them enrolled in Medicare Half B and Half D.
They’d prefer to know the way it impacts their taxes in the event that they convert completely different quantities from their Conventional IRA to Roth.
Age and Submitting Standing
Click on on the Calculations tab on the backside of the spreadsheet. First, you enter your submitting standing, your variety of dependents, and ages in green-shaded cells beginning at cell G2.
You go all the way down to cell H37 to enter your state of residency.
Earnings and Medicare
Subsequent, you enter your earnings. As a result of the couple in our state of affairs are each retired, we skip the paycheck gadgets and go all the way down to the non-paycheck earnings beginning at cell D23. You solely enter into cells shaded in inexperienced. Use annual numbers right here.
As a result of they’re each on Medicare, we enter their Medicare Half D premium in cell AF78. That is the month-to-month premium for one particular person. In the event that they’re on completely different Half D plans, use the common premium of the 2 plans. Right here we assume their month-to-month Half D premium is $40 per particular person.
Baseline Taxes
Now we return to the tax calculation space beginning at cell F11. This exhibits their baseline earnings taxes.
This retired couple with a gross earnings of $95,000 pays $2,015 in taxes. That’s solely a bit of over 2% of their gross earnings.
Discover Roth Conversion
This couple is curious about doing Roth conversion to make the most of their low tax charges. Scroll all the way down to cell F81 to see a chart like this:
It exhibits the marginal and cumulative tax charges at completely different quantities of withdrawals from their Conventional IRA. The quantity on the X-axis consists of the $20,000 they’re already withdrawing from their Conventional IRAs for dwelling bills.
We make a number of tweaks to see the chart higher.
Regulate the Chart Scale
By default, the Y-axis within the chart goes between -50% and +50%. The underside half of the chart is empty proper now. Choose the Y-axis within the chart, right-click, and click on on Format Axis… Set the minimal to 0 and the utmost to 0.6. It’ll use the total house for the chart.
Set the Beginning Level
As a result of this couple already withdraws $20,000 from their Conventional IRAs for dwelling bills, we are able to set the start line at $20,000 to guage solely withdrawals above and past $20,000 for a Roth conversion. Enter 20,000 in cell P84. Now the chart seems like this:
It exhibits that changing about $25,000 (to take the entire withdrawal from Conventional IRAs to $45,000) will incur a marginal tax fee of about 22%. Then the marginal tax fee spikes as much as 50% earlier than it settles all the way down to 22% once more when the entire withdrawals hit about $55,000.
The spike is the so-called tax torpedo, which occurs when extra earnings makes extra of the Social Safety advantages taxable (see earlier submit Calculator: How A lot of My Social Safety Advantages Is Taxable?). Though the 50% marginal tax fee seems scary, it applies to solely a sliver of their earnings. As they improve their Roth conversion to $90,000, the impact of the “tax torpedo” will get unfold out. It solely causes a slight improve of their cumulative tax fee (the blue line) — from 22% to 23%. The “tax torpedo” is extra like a small ding than a torpedo for this couple.
Lengthen the Vary
Growing the quantity in cell P83 will prolong the X-axis within the chart to bigger numbers. For instance, altering cell P83 to $700 makes the chart appear like this:
The subsequent 4 spikes within the marginal tax fee (the grey line) symbolize Medicare IRMAA. Level your mouse at factors earlier than the blue line jumps up. You’ll see the entire Conventional IRA withdrawals and the cumulative tax fee related to every leap. Subtract the baseline Conventional IRA withdrawals for dwelling bills from the entire Conventional IRA withdrawals to get the quantity for Roth conversion.
The chart exhibits they’ll pay about 23% in taxes on their Conventional IRA withdrawals in the event that they convert $115k earlier than their earnings hits the primary threshold for IRMAA. The cumulative tax fee can be 24% in the event that they convert $165,000 and cease earlier than the second IRMAA tier, 26% in the event that they convert $230,000 and cease earlier than the third IRMAA tier, and so forth.
| Break Level | Roth Conversion Quantity | Cumulative Tax Price |
|---|---|---|
| Earlier than “tax torpedo” | $25,000 | 22% |
| Earlier than the primary IRMAA tier | $115,000 | 23% |
| Earlier than the second IRMAA tier | $165,000 | 24% |
| Earlier than the third IRMAA tier | $230,000 | 26% |
This couple can determine how a lot to transform based mostly on the dimensions of their pre-tax accounts and their view of tax charges sooner or later. Convert extra if they’ve giant pre-tax accounts they usually suppose tax charges can be excessive sooner or later. Convert much less in the event that they don’t have giant pre-tax accounts they usually suppose tax charges can be low sooner or later.
The form and the breakpoints on your particular state of affairs can be completely different. You’ll be able to comply with this instance and use the chart to map your individual breakpoints and tax charges.
Save the Spreadsheet
You might even see a warning like this if you save the spreadsheet:
That is regular. Click on on Proceed and the spreadsheet can be saved.
Situation – Single
I’ll do one other instance for somebody within the Single submitting standing.
A retired particular person, age 66, Florida resident, single with no dependents, enrolled in Medicare Half B and Half D. She lives on $30,000 of Social Safety advantages, $20,000 of Conventional IRA withdrawals, $2,000 of curiosity earnings, and $5,000 of certified dividends. She has no different earnings or deductions.
Coming into 1 in cell G2 for the Single submitting standing and go away grownup #2 clean.
Enter the earnings in the identical green-shaded cells beginning at cell D23:
After you modify the chart scale, set the start line, and prolong the vary of the X-axis, the chart seems like this:
The primary spike within the marginal tax fee (the grey line) is the so-called “tax torpedo.” The subsequent 4 spikes are as a consequence of Medicare IRMAA. Level your mouse at factors earlier than every leap within the blue line. You’ll see the entire Conventional IRA withdrawals and the cumulative tax fee related to every leap. Subtract the baseline Conventional IRA withdrawals for dwelling bills from the entire Conventional IRA withdrawals to get the quantity for Roth conversion.
Listed below are the corresponding breakpoints and tax charges:
| Break Level | Roth Conversion Quantity | Cumulative Tax Price |
|---|---|---|
| Earlier than “tax torpedo” | $8,500 | 22% |
| Earlier than the primary IRMAA tier | $48,000 | 25% |
| Earlier than the second IRMAA tier | $74,000 | 26% |
| Earlier than the third IRMAA tier | $105,000 | 27% |
| Earlier than the fourth IRMAA tier | $135,000 | 27% |
She will be able to determine how a lot to transform relying on the dimensions of her pre-tax accounts and her view of tax charges sooner or later. Convert extra if she has giant pre-tax accounts and he or she thinks tax charges can be excessive sooner or later. Convert much less if she doesn’t have giant pre-tax accounts and he or she thinks tax charges can be low sooner or later.
Once more, the form and the breakpoints on your particular state of affairs can be completely different. You’ll be able to comply with this instance and use the chart to map your individual breakpoints and tax charges.
Limitations
The Case Research Spreadsheet is a wonderful instrument to discover how changing completely different quantities to Roth impacts your taxes, however the a part of the spreadsheet used on this submit exhibits solely the present 12 months. It doesn’t present the impact of doing so over a few years.
For instance, you see that you’ll pay X% in taxes if you happen to convert this a lot now, however you don’t know whether or not changing extra (or much less) can be higher in the long term if you bear in mind the dimensions of your pre-tax accounts, your age, your spending wants, funding returns, your Required Minimal Distributions (RMD), and so on., and so on. You’ll should determine your self whether or not paying X% in taxes on Roth conversion is “value it.”
Different software program instruments comparable to Optimum Retirement Planner (ORP), Retiree Portfolio Mannequin (RPM), and Pralana Gold look throughout a number of years based mostly on a set of inputs and assumptions to recommend an quantity you need to convert to Roth every year. The large query is whether or not these inputs and assumptions will maintain true.
Mike Piper, CPA made argument in opposition to projecting out too a few years in his weblog submit Lengthy-Time period Tax Planning Requires Guessing. Give attention to the Close to-Time period. The long run can’t be predicted exactly. Your spending wants will change. Funding returns could also be sturdy or weak. Tax legal guidelines change. You received’t know what your tax charges can be sooner or later.
I see motive to solely take a look at the present 12 months with the Case Research Spreadsheet. The choice received’t be “optimum” however attempting to “optimize” could also be solely chasing rainbows. I attempt to banish the phrase “optimize” from my monetary life and from life basically.
***
The aim of a Roth conversion is to make the most of low tax charges. In case your retirement is dicey, the most effective Roth conversion technique received’t remedy it. In case your retirement is safe, an inexpensive try at Roth conversion is barely attempting to make an already good scenario higher. So don’t get wired if you don’t know the way a lot you need to convert. You need to use the Case Research Spreadsheet to discover a affordable reply for the present 12 months.
