For several years, many planning discussions were shaped by the expected expiration of lower individual tax rates at the end of 2025. That pressure has eased because federal tax legislation enacted in 2025 made the individual income tax rates from the 2017 tax law permanent. So does that mean Roth conversions simply aren’t worth it or necessary anymore?
At WealthGen, we don’t see any solid reasons to throw the Roth into the dustbin. But the reasons for converting need to be more precise than simply racing to convert before taxes go back up.
A conversion should be tied to a potentially better lifetime tax picture, reduced future required distributions, stronger retirement income flexibility, or a more thoughtful estate plan. A conversion becomes much harder to justify when it is driven by fear, headlines, or a desire to move everything into a Roth without measuring the tax cost.
A Roth conversion is a deliberate trade. You voluntarily move pretax retirement dollars into a Roth account and include the taxable portion in your current income. In exchange, qualified Roth IRA distributions may later be excluded from income, and Roth IRAs do not require lifetime required minimum distributions for the original owner. Conversions are not subject to the same income limits that restrict direct Roth IRA contributions, although the taxable portion of a conversion can push income into a higher bracket.
For high-net-worth business owners and executives with employee stock options, the tax implications of those options require careful modeling because income rarely arrives in neat annual patterns. A strong income year can be followed by a slow year, a company sale, a vesting event, a stock option exercise, a large charitable gift, or a change in residency. Those moments often decide whether a Roth conversion is efficient or expensive.
The 2026 planning window is about precision
The old tax sunset should no longer drive the whole decision. Since the lower individual rates were made permanent, a Roth conversion in 2026 should be evaluated on its own merits rather than treated as a race against a disappearing bracket. Now, remember, permanent does not mean Congress can never change the rules. It simply means the automatic expiration that once dominated this planning conversation is no longer the same force.
That matters because a conversion cannot be casually undone; the IRS notes that conversions from a traditional IRA to a Roth IRA after 2017 may not be recharacterized. Once the conversion is complete, the tax result generally stays with you. That single rule is enough reason to slow down and model the decision before moving assets.
Bracket room matters more than the headline rate
A thoughtful Roth conversion often starts by measuring available room inside a desired tax bracket. For example, a married couple filing jointly with $320,000 of projected taxable income before any conversion would have roughly $83,550 of room before reaching the 32 percent bracket in 2026. That does not automatically mean they should convert that full amount. It means the bracket math gives them a starting point for deeper analysis.
The better calculation looks at the full tax return. A conversion can affect capital gains exposure, Medicare-related taxes, deduction phaseouts, estimated tax payments, state taxes, charitable planning, and the timing of business income. The conversion amount that fits neatly within a federal bracket may still be too large once the full household picture is considered.

Bracket Room Is Where the Math Begins
A sample household sits well inside the 24% bracket. The space before the next rate is only the opening filter. Four secondary considerations often shrink the true room available for a Roth conversion.
Secondary Filters That Shrink True Room
Medicare (IRMAA)
A larger conversion raises MAGI, which can push Part B and Part D premiums into higher tiers two years later.
Capital Gains Stacking
Ordinary conversion income stacks under long-term gains and may raise the rate applied to those gains.
Deduction Phaseouts
Senior, SALT, and itemized limitations begin to reduce as income climbs, raising the effective cost per dollar.
Charitable Giving
QCDs and donor-advised fund gifts can lower AGI first, changing the optimal conversion size in the same year.

Why Roth conversions can still add value
They can reduce future required distribution pressures
Traditional IRAs, SEP IRAs, SIMPLE IRAs, and many employer retirement plans eventually force taxable withdrawals through required minimum distributions. The IRS states that account owners generally must begin taking required minimum distributions at age 73, while Roth IRAs and designated Roth accounts are not subject to required minimum distributions during the original owner’s life.
That difference can matter for families with large pretax retirement balances. A business owner who has spent decades funding a 401(k), profit-sharing plan, SEP IRA, or traditional IRA may enter retirement with a large future tax liability sitting quietly on the balance sheet. Converting a portion before required distributions begin can reduce the size of future forced withdrawals, especially during the years after a business exit and before Social Security, pensions, or required distributions fully begin.
The conversion does not need to be dramatic. In many cases, smaller annual conversions over several years are more disciplined than one large conversion. The aim is to reduce the most expensive future income without creating an unnecessary current tax spike.
They can improve retirement income flexibility
A retirement plan that holds taxable, pretax, and Roth accounts gives more control over which dollars are used in a given year. Fidelity describes this as tax diversification, in which different account types can give retirees more flexibility as their income, tax law, and spending needs change.
That flexibility is especially useful for families with concentrated wealth. A business owner may have a large taxable liquidity event, real estate income, carried-over capital losses, charitable giving goals, and retirement accounts, all interacting simultaneously. A Roth balance can create another source of funds that may be less disruptive to the tax return when income needs change.
This is where technology matters. A good planning process should test multiple retirement income sequences instead of relying on a single projection. The value of a Roth conversion is rarely visible in one tax year. It usually shows up across a series of years, especially when the plan measures income taxes, investment location, withdrawal order, future required distributions, and estate goals together.
They can help with generational wealth planning
Roth conversions can also support legacy planning when heirs are likely to inherit retirement assets during high-earning years. Most non-spouse beneficiaries of inherited IRAs are subject to the ten-year distribution rule, which can compress taxable inherited traditional IRA withdrawals into a shorter period. The IRS explains that for many beneficiaries of accounts whose owners died after 2019, the account must be distributed within 10 years, with exceptions for certain eligible beneficiaries.
A Roth IRA does not change the beneficiary distribution rules, but inherited Roth IRA withdrawals are generally more tax-favorable once the required Roth aging rules have been met. Fidelity notes that inherited Roth IRA assets generally have no immediate income tax impact, and withdrawals are generally tax-free if the original owner satisfied the five-year aging requirement.
For families trying to preserve generational wealth, this can be meaningful. Paying tax at the owner’s generation may be attractive when heirs are expected to be in high brackets, live in high tax states, or inherit during their own peak earning years. The opposite can also be true. If heirs are likely to be in much lower brackets, keeping assets in a traditional account may be more efficient.
Estate size also matters. The federal estate tax basic exclusion amount for 2026 is $15,000,000 per person. That reduces immediate federal estate tax exposure for many affluent families, while still leaving income tax planning, asset location, state tax, and beneficiary design as major planning concerns.
Where 2026 conversions can become costly
Deduction phaseouts can raise the effective tax rate
The posted federal bracket is only part of the story. In 2026, several deductions and limitations can make the effective cost of a Roth conversion higher than the stated marginal bracket suggests.
The enhanced senior deduction applies from 2025 through 2028 for eligible taxpayers age 65 and older; for 2026, it can be as high as $6,000 per eligible taxpayer, or $12,000 when both spouses qualify, and it begins to phase out when modified adjusted gross income exceeds $75,000 for single filers or $150,000 for joint filers. The state and local tax deduction limit for 2026 is $40,400, or $20,200 for married filing separately, and it begins to phase down when modified adjusted gross income exceeds $505,000, or $252,500 for married filing separately; however, the limit is not reduced below $10,000, or $5,000 for married filing separately.
Overall itemized deductions may also be reduced when taxable income exceeds $768,700 for married joint filers or qualifying surviving spouses, $640,600 for single filers or heads of household, or $384,350 for married filing separately; for 2026, the reduction is 5.4% of the lesser of total itemized deductions or the amount taxable income exceeds the applicable threshold.
That means the true cost of a conversion can be higher than 24 percent, 32 percent, or 35 percent once lost deductions and other income-based limits are included. This is one of the main reasons I prefer measured conversions supported by tax projection software to broad rules of thumb.
Investment income can be affected even when the conversion itself is not investment income
A Roth conversion is generally ordinary income, not net investment income. Even so, it can increase modified adjusted gross income and expose more investment income to the 3.8 percent net investment income tax. IRS Publication 505 states that the net investment income tax is 3.8 percent of the lesser of net investment income or the amount by which modified adjusted gross income exceeds $200,000 for single filers, $250,000 for married joint filers, and $125,000 for married filing separately.
This matters for high-net-worth families with taxable portfolios, private investments, rental income, business sale proceeds, or concentrated stock positions. A conversion that looks reasonable when viewed only through the lens of ordinary income brackets may become less attractive once investment income, capital gains, and estimated tax requirements are taken into account.
Employee stock options require careful coordination
Executives with employee stock options need special care. The IRS explains that exercising incentive stock options can create an AMT adjustment when the stock becomes transferable or is no longer subject to a substantial risk of forfeiture, although no AMT adjustment is required if the stock is disposed of in the same year as the exercise. For most nonstatutory stock options without a readily determinable fair market value at grant, taxable compensation is generally recognized on exercise, but if the acquired stock is not substantially vested at exercise, income is recognized when it becomes substantially vested.
That makes timing critical. A large Roth conversion in the same year as a nonstatutory option exercise, restricted stock vesting, or significant W 2 income can create a stacked ordinary income problem. A conversion in the same year as an incentive stock option exercise may also complicate alternative minimum tax planning. The better approach is to map out option exercises, expected sales, vesting schedules, withholding, and conversion amounts on a single calendar before making decisions.
Charitable intent can change the answer
A Roth conversion is often less attractive when the retirement account is ultimately intended for charity. Fidelity notes that traditional accounts can typically be left to charity without the charity paying income tax, whereas converting those assets first can cause the owner to pay income tax that might otherwise have been avoided.
For families with meaningful charitable goals, this point deserves attention. A traditional IRA can sometimes be an efficient charitable asset, while Roth assets may be better reserved for family beneficiaries. The right answer depends on beneficiary design, estate documents, charitable intent, age, required distributions, and the mix of taxable and retirement assets.
Pre-Conversion Review
A 2026 Roth Conversion Checklist
Ten items to confirm before moving pretax dollars into a Roth. Tap each card as you review. The checklist is for personal reflection only, not a record or submission.
This checklist is educational and does not constitute individualized tax, legal, or investment advice. Roth conversions may involve state tax, Medicare, and estate considerations not represented here. Consider reviewing your situation with a qualified advisor before acting.
How to Evaluate a 2026 Roth Conversion
Start with a three-year income map. Include salary, bonus, business income, K-1 income, stock option exercises, restricted stock vesting, expected capital gains, charitable gifts, required distributions, Social Security, pension income, real estate income, and any planned business sale proceeds.
Then model the household tax return before choosing a conversion amount. Compare no conversion, a partial conversion, and a larger conversion. Show federal and state taxes, Medicare-related effects, net investment income tax exposure, capital gains effects, deduction phaseouts, and estimated tax requirements.
Next, test the impact on retirement. Compare future required distributions, projected taxable income in retirement, withdrawal order, asset location, investment costs, and the effect on a surviving spouse. A surviving spouse may later file as a single taxpayer, often with compressed tax brackets and similar household assets.
Finally, test the estate result. Compare the tax outcome for heirs, charities, trusts, and the surviving spouse. For families focused on generational wealth, Roth planning often becomes more than just a retirement income decision. It becomes part of how wealth moves from one generation to the next. 1: Do Roth Conversions In 2026 Still Make Sense_.md

No Conversion
Leave pretax balances in place and address income taxes as withdrawals are taken. The simplest path, but it defers the decision rather than solving it.
No voluntary income recognized this year.
Entire account remains subject to RMDs beginning at age 73.
Non-spouse heirs generally face a 10-year drawdown at their own rates.
No outside cash required to fund conversion tax.
