In Part 1 and Part 2, Ben and Leslie discovered something uncomfortable as they planned their early retirement withdrawals. They weren’t running out of money, but they were running out of accessible money.
Most of their wealth lived inside retirement accounts they couldn’t easily access before age 59½. If they relied on just their taxable brokerage for spending, the account ran dry at age 58.
Now it’s time to build the bridge properly. The question we’re trying to solve for is:
How do Ben and Leslie create a reliable paycheck between ages 50 and 59½ without blowing up taxes, losing ACA subsidies, or locking themselves into a rigid withdrawal strategy?
As a reminder, here’s where Ben and Leslie start at age 50:
| Account | Balance | Cost Basis |
| Traditional 401(k) / IRA | $1,600,000 | — |
| Roth Accounts | $300,000 | $100,000 |
| Taxable Brokerage | $600,000 | $300,000 |
| Total | $2,500,000 | — |
Their target spending is $90,000 per year. The assumptions behind the projections:
- Portfolio growth: 6%
- Inflation: 2.5%
- Taxable dividend yield: 1.5% (95% qualified)
- ACA health insurance costs are included in spending ($10,000 per year)
- Goal: remain below 400% of the federal poverty level to preserve ACA premium tax credits
But before we jump into spreadsheets, it’s worth defining what success actually looks like. We’re evaluating each strategy across four categories:
| Goal | Why It Matters |
| 1. Cash Flow Stability | Can Ben and Leslie reliably fund retirement spending? |
| 2. Tax Efficiency | Are they making use of low tax brackets and the standard deduction? |
| 3. ACA Optimization | Can they preserve affordable healthcare subsidies? |
| 4. Flexibility | Can the plan adapt if markets or life circumstances change? |
scenario 1: 72(t) AKA SEPP
A Rule 72(t) SEPP plan allows retirees to access retirement accounts early without the 10% penalty, provided they agree to take “substantially equal periodic payments” for at least five years or until age 59½, whichever is longer. The biggest advantage of a 72(t) is that it creates income immediately.
For Ben and Leslie, we’ll assume they move $700,000 into a separate IRA and generate fixed annual withdrawals of roughly $40,000 per year. That immediately reduces pressure on the taxable brokerage account. Here’s what the next decade looks like:
| Age | Eff. Spend | Dividends | 72(t) SEPP | Brk. Draw | Fed Tax | % FPL |
| 50 | $86,770 | $9,000 | $40,000 | $38,595 | $825 | 315.6% |
| 51 | $89,225 | $8,637 | $40,000 | $41,331 | $743 | 317.7% |
| 52 | $91,770 | $8,495 | $40,000 | $43,935 | $659 | 320.6% |
| 53 | $94,381 | $8,305 | $40,000 | $46,650 | $574 | 323.4% |
| 54 | $97,060 | $8,061 | $40,000 | $49,485 | $486 | 326.3% |
| 55 | $99,797 | $7,758 | $40,000 | $52,436 | $396 | 329.2% |
| 56 | $102,602 | $7,389 | $40,000 | $55,515 | $303 | 332.1% |
| 57 | $105,477 | $6,951 | $40,000 | $58,734 | $207 | 334.9% |
| 58 | $108,425 | $6,435 | $40,000 | $62,100 | $109 | 337.8% |
| 59 | $111,448 | $5,835 | $40,000 | $65,621 | $8 | 340.6% |
The results are surprisingly effective. By replacing part of their annual spending with SEPP/72(t) income:
- Their brokerage account survives into their 60s
- ACA subsidies remain largely intact
- Federal taxes stay extremely low
- The “bridge problem” effectively disappears
Even though they are receiving $40,000 per year from retirement accounts, much of the rest of their spending still comes from brokerage basis withdrawals and qualified dividends, keeping taxable income relatively modest. Their long term capital gains stay within the zero percent tax bracket.
It is worth noting that this simplicity comes with tradeoffs. A 72(t) plan is rigid. Once started, the payment stream generally cannot be modified without triggering retroactive penalties on prior withdrawals. If spending needs change, markets perform poorly, or Ben and Leslie simply want more flexibility, the IRS is not especially forgiving.
In other words: a 72(t) solves the bridge problem by sacrificing flexibility.
For retirees who already have a shortfall and need immediate retirement account access, that tradeoff may be worthwhile.
A Roth conversion ladder approaches the problem differently.
Scenario 2: The Roth Conversion Pipeline
Instead of creating income today, a Roth conversion ladder creates future access. What does this look like?
Ben and Leslie can convert money from their Traditional IRA into a Roth IRA each year. The conversion is taxable ordinary income, and once the converted funds have aged five years, they can be withdrawn tax and penalty-free. In this scenario, Ben and Leslie convert $30,000 per year starting at age 50. Because the standard deduction offsets the conversion income, their federal tax bill remains extremely low (zero!).
During the first several years, the converted funds are still “seasoning” inside the Roth IRA. Ben and Leslie must continue relying primarily on their taxable brokerage account for living expenses. The payoff comes later, when the earlier conversions begin becoming accessible.
Here’s what that looks like in practice:
| Age | Eff. Spend | Roth Conv. | Brk. Draw | Roth Draw | % FPL | Fed Tax |
| 50 | $88,263 | $30,000 | $79,263 | – | 363.40% | – |
| 51 | $90,818 | $30,000 | $83,133 | – | 367.90% | – |
| 52 | $93,490 | $30,000 | $86,659 | – | 373.50% | – |
| 53 | $96,222 | $30,000 | $90,347 | – | 378.90% | – |
| 54 | $99,021 | $30,000 | $94,219 | – | 383.90% | – |
| 55 | $101,890 | $30,000 | $98,287 | – | 388.70% | – |
| 56 | $104,825 | $30,000 | $102,557 | – | 393.20% | – |
| 57 | $107,828 | $30,000 | $103,676 | $3,366 | 388.70% | – |
| 58 | $99,656 | – | – | $99,656 | 0.00% | – |
| 59 | $102,398 | – | – | $100,000 | 0.00% | – |
At first glance, the Roth ladder appears to create the same problem that Ben and Leslie were initially facing: their taxable brokerage account runs dry before 59 ½.
But if you look at the rows for age 58 and 59, you can see what changed. Ben and Leslie have built a growing pool of accessible Roth conversion dollars. Instead of relying on taxable assets, they are now funding retirement from prior Roth conversions that have completed the five-year waiting period.
This approach creates more flexibility than a 72(t), but it also exposes an interesting ACA planning problem.
The ACA Income Problem
Astute readers will notice that Ben and Leslie are generating zero taxable income by ages 58 and 59 because they are living off prior Roth conversions. That sounds ideal from a tax perspective, but extremely low income can create ACA complications. Ben and Leslie’s Modified Adjusted Gross Income (MAGI) could fall low enough that they would likely qualify for Medicaid and no longer be eligible for ACA premium subsidies. Depending on the retiree, that may or may not be desirable.
- The goal is not generally minimizing income to zero.
- The goal is generating the right kind of income in the right amounts.
That realization leads many early retirees toward a hybrid strategy.
Scenario 3: The Hybrid Approach
The most effective bridge strategies often are hybrids that rely on multiple strategies. Instead of relying entirely on brokerage withdrawals, entirely on 72(t) income, or entirely on Roth conversions, Ben and Leslie can coordinate all three options together.
What might that look like?
A modest 72(t) that:
- Creates immediate spending cash flow
- Reduces pressure on the brokerage account during the early years of retirement
- Helps preserve ACA subsidy eligibility
At the same time:
- Roth conversions to intentionally fill lower tax brackets
- Future tax-free assets continue growing
- Long-term flexibility improves
Rather than trying to minimize taxes in any single year, the hybrid strategy focuses on optimizing taxes across decades.
As an example, Ben and Leslie could establish a $40,000 per year 72(t) payment to cover part of their annual spending needs while simultaneously performing Roth conversions each year up to 399% of the federal poverty level to preserve some ACA premium tax credits.
| Age | Eff. Spend | Roth Conv. | Brk. Draw | Ordinary income (72t, Roth conversion, NQ div.) | % FPL | Fed Tax |
| 50 | $89,398 | $13,000 | $42,523 | $53,450 | 385% | $2,125 |
| 51 | $91,855 | $13,000 | $45,353 | $53,427 | 386% | $2,042 |
| 52 | $94,410 | $13,000 | $48,034 | $53,417 | 387% | $1,959 |
| 53 | $97,030 | $13,000 | $50,831 | $53,404 | 389% | $1,873 |
| 54 | $99,715 | $13,000 | $53,752 | $53,387 | 390% | $1,784 |
| 55 | $102,467 | $13,000 | $56,802 | $53,368 | 392% | $1,694 |
| 56 | $105,289 | $13,000 | $59,990 | $53,345 | 394% | $1,600 |
| 57 | $108,181 | $13,000 | $63,325 | $53,318 | 395% | $1,504 |
| 58 | $111,145 | $13,000 | $66,813 | $53,287 | 397% | $1,405 |
| 59 | $114,182 | $13,000 | $70,465 | $53,251 | 398% | $1,304 |
That combination creates immediate accessible income, gradually builds a larger Roth pipeline for future years, and prevents them from wasting valuable low-tax-income years entirely. Ben and Leslie are now paying $1k-$2k in federal income taxes each year, but that is still an effective tax rate of only 1-2%.
In practice, this is where many sophisticated early retirement plans eventually land: not on a single strategy, but a coordinated system of withdrawals, conversions, subsidies, and tax management working together.
Once retirees understand how taxable accounts, Roth conversions, SEPPs, and ACA subsidies interact, the wall around retirement accounts starts looking much less like a prison and much more like a timing puzzle.
If Ben and Leslie are the worrying types, then they can start thinking about an entirely different problem.
What happens if their investments are too successful?
In the next part, we’ll explore how low-income early retirement years can become an opportunity for long-term tax planning, and why retirees with large pre-tax balances may eventually need to worry less about running out of money and more about future required minimum distributions, IRMAA surcharges, and lifetime tax exposure.
