When a client asks, “Should I complete a Roth conversion?”, it can feel like stepping into the unknown. There’s no turning back — recharacterizations are no longer allowed, and once you convert, the tax bill is locked in.
But uncertainty doesn’t mean guesswork or needing a crystal ball. Instead, with the right modeling and analytics, advisors can turn ambiguity into precision. Here are three key considerations — and the hidden risks that often go overlooked.
Should I Convert?
What clients are really asking: Will paying taxes now yield more tax-free growth later — net of risks and opportunity cost?
Key factors to weigh:
- Current vs. future tax rates: If future marginal rates are likely to rise, conversion today may hedge that risk.
- Time horizon: Longer tax-free growth can overcome the upfront “tax drag.”
- Estate goals: Roth IRAs avoid RMDs and can be more favorable to heirs.
- Income interactions: Conversions may trigger IRMAA surcharges or increase Social Security taxation — often missed in basic modeling.
💡 Quick check: If paying tax now and future tax-free growth beats tax-deferred growth and later taxes, clients should consider converting.
How Much Tax Will I Owe? Precision Matters
Clients need clarity — not surprises. Estimating the tax impact accurately is key to buy-in.
Watch for these traps:
- Bracket creep: Large conversions can push income into higher marginal brackets — a hidden shock if not modeled incrementally.
- IRMAA & Social Security: Higher income years can spike Medicare premiums and increase taxable Social Security — two of the most overlooked risks.
- Tax funding strategy: Using IRA assets to pay the tax may feel convenient but erodes long-term growth — a costly mistake.
- Pro rata rule: You can’t only convert the after-tax amount. All Traditional, SEP and SIMPLE IRAs a client has are aggregated, and conversions are taxed proportionally.
📊 Example: A $50K conversion from a $200K IRA with $20K after-tax = $45K taxable income.
When is it Optimal for Me to Convert? Timing Is Tactical
Conversion timing can make or break the strategy.
Best-case windows:
- Low-income years: Early retirement, sabbaticals, or business transitions offer bracket space.
- Market dips: Lower account values during market downturns mean you pay less tax on the conversion now, while positioning the converted funds for potential tax-free growth in the future.
- Layered conversions: Spread across years to avoid bracket jumps and IRMAA cliffs.
- Before RMDs: Once RMDs begin, taxable income may diminish conversion opportunities. RMDs cannot be converted – investors are often not aware of this.
- Legislative Opportunity: Use today’s favorable tax rates before potential policy changes — a risk often overlooked.
⏳ Pitfall alert: If retirement is near, there may not be enough runway for the tax-free growth to offset the upfront cost.
No Crystal Ball? No Problem — Break Analytics Brings Clarity
Break Analytics helps advisors model Roth conversions with precision. You can:
- Run multi-dimensional scenarios (tax, growth, inflation, MAGI)
- Forecast Medicare IRMAA surcharges to help clients understand the full cost of conversion
- Identify optimal conversion thresholds year-by-year
- Stress-test for tax rate shifts and legislative changes
- Re-run assumptions as client income evolves
- Present clear, defensible recommendations
No more guesswork — just a confident, quantifiable strategy.
Roth Conversion Frequently Asked Questions
No. Recharacterizations (undoing a conversion) have been eliminated.
Yes. There is no income limit on conversions. Even high earners can convert a Traditional IRA to Roth.
If you distribute converted amounts before completing the five-year conversion clock and you are not at least age 59½, you may incur a 10% early distribution tax on that converted amount (unless exceptions apply). Each conversion has its own 5-year clock. Once your Roth IRA has been opened for more than 5 years (different clock) and you are at least age 59 ½, all distributions are Qualified, meaning no tax or 10% additional tax.
When you distribute from a Roth IRA, the IRS applies this order:
Contributions – Always come out first. These are tax- and additional 10% tax-free since they were made with after-tax dollars.
Conversions – Come out next, in the order they were made (first-in, first-out). Each conversion has a separate 5-year clock to avoid the 10% additional tax.
Earnings – Come out last. Earnings are tax- and 10% additional tax-free only if:
– The Roth IRA has been open at least 5 years, and
– You’re age 59½ or older, or the distribution is due to your death, or your disability, or as a first-time homebuyer.
Otherwise, earnings may be taxed, including the 10% additional tax unless an exception applies.
The taxable income from a Roth conversion increases your modified adjusted gross income (MAGI) in the year of the conversion. This higher MAGI can trigger Medicare IRMAA surcharges, but the impact is delayed, because IRMAA is based on income from two years prior. This timing often catches people off guard.
The break-even horizon is the number of years needed such that the future tax-free growth offsets the upfront tax cost. It varies depending on tax rates, growth assumptions, and distribution behavior. Using modeling tools helps compute this per scenario.
