In our 510,000-path Monte Carlo study of 30-year retirement outcomes, Pennsylvania retirees finished at 76.53% success rate (ranked #4 of 51 by success rate, #8 of 51 by lowest median lifetime state tax). Median 30-year state-tax cost: $0. Median terminal balance after 30 years: $995,266. State tax is part of the optimization here — the playbook below shows the federal-state-ACA stack.
The PA verdict
For a retiree planning withdrawals in 2026, Pennsylvania is broadly retirement-tax-friendly, with most distributions sheltered. One flat bracket that exempts all qualified retirement income, with an inheritance tax of 0-15%.
Pennsylvania exempts qualified retirement income — pensions, 401(k) and IRA distributions alike — so a withdrawal costs $0 in state income tax, and a conversion out of one of those accounts is treated the same way. The binding constraints on a Pennsylvania conversion ladder are the federal bracket, the 400% FPL ACA cliff and the IRMAA two-year lookback, not the state rate.
Worked example: $30k Roth conversion in Pennsylvania
Consider a married couple age 58 in Pennsylvania with $75,000 of taxable income, both on ACA Marketplace coverage. They want to convert $30,000 from a traditional IRA to a Roth. The Pennsylvania state tax on that conversion is approximately $0 — Pennsylvania exempts qualified retirement income, and a conversion is a distribution from a qualified account. Federal tax at the 22% bracket adds another $6,600. And because the conversion pushes their MAGI to $105,000 — over the 400% FPL cliff of $84,600 — they lose their full ACA premium tax credit, roughly $12,000. Total cost of the $30,000 conversion: about $18,600, or an effective 62.0% marginal rate. Pennsylvania applies one rate to all taxable income, so that state figure is the full amount before any deduction Pennsylvania allows. The federal-state-ACA stack matters in Pennsylvania.
Cost breakdown
| Component | Amount |
|---|---|
| Federal income tax (22% bracket) | $6,600 |
| Pennsylvania state income tax | $0 |
| ACA premium tax credit clawback | $12,000 |
| Total cost on $30,000 conversion | $18,600 (62.0% effective) |
Scenario B (friendly): $50k post-65 conversion in Pennsylvania
A married Pennsylvania couple age 67, both on Medicare, with $40K pension income converts $50,000 in a single year. State tax owed: $0 — Pennsylvania exempts qualified retirement income, and a conversion is a distribution from a qualified account. Federal tax at 22%: ~$11,000. No ACA clawback (on Medicare). Total: $11,000, or 22.0% effective. The post-65 conversion window is where a Pennsylvania ladder is cheapest.
What the Monte Carlo data says about Pennsylvania
QuantCalc Research ran a 30-year, 10,000-path Monte Carlo simulation for an identical representative retiree (age 60, $2M starting balance, 60/40 portfolio, $80K real annual spend) in each of the 51 U.S. jurisdictions. Here's how Pennsylvania compared to the best- and worst-case states:
| Metric | Pennsylvania | Wyoming (best) | California (worst) |
|---|---|---|---|
| 30-year success rate | 76.53% | 77.11% | 69.03% |
| Rank (of 51) | #4 | #1 | #51 |
| Median lifetime state tax (30y) | $0 | $0 | $154,980 |
| Median total tax (30y) | $218,400 | $218,400 | $373,380 |
| Median terminal balance | $995,266 | $999,751 | $695,612 |
| Δ success vs Wyoming | -0.58 pp | — | −8.08 pp |

How Pennsylvania treats capital gains in retirement
Pennsylvania taxes capital gains at the flat 3.07% rate — the same as wages and ordinary income — but it does not allow capital-loss offsets against ordinary income at the state level.
Why the ACA cliff hits hard in Pennsylvania
The 400% federal-poverty-level cliff is federal, not state-specific — but its dollar impact depends on the benchmark Silver-plan premium in your county. Pennsylvania's Marketplace pricing and your household composition determine the size of the subsidy at risk. A two-person household near 400% FPL can easily have $10,000–$15,000 of annual premium tax credit on the line. Under the OBBBA 2026 restoration of the cliff, $1 of additional MAGI above 400% FPL eliminates the entire credit.
For 2026 the 400% FPL threshold is:
- Household of 1: $62,600
- Household of 2: $84,600
- Household of 3: $106,600
- Household of 4: $128,600
Optimal Roth conversion strategy for Pennsylvania
The PA-specific playbook depends on tier:
- Identify your cliff distance. Compute MAGI from all income sources (wages, capital gains, interest, dividends, traditional withdrawals). Find your headroom under 400% FPL. Use the live cliff widget above for a quick check.
- Stay under the cliff if you can. In Pennsylvania at 3.07%, the marginal cost of going over the cliff is federal tax + state tax + full PTC clawback. The break-even conversion size is smaller than in tax-free states.
- If you must go over, convert big. Once you've crossed the cliff, additional conversion dollars only cost federal + state tax (no incremental PTC loss). A "rip the bandage" conversion year can be efficient if you have many traditional dollars to move.
- Coordinate with capital gains and the 0% LTCG bracket. Pennsylvania taxes capital gains at the flat 3.07% rate — the same as wages and ordinary income — but it does not allow capital-loss offsets against ordinary income at the state level.
- Plan ahead for IRMAA. The IRMAA Medicare premium surcharge has a 2-year lookback. A Pennsylvania resident in their early 60s converting today will see IRMAA implications at 65. See RMD + IRMAA calculator for the lookback math.

FAQ
Does Pennsylvania tax Roth conversions?
Pennsylvania taxes Roth conversions as ordinary income at the state level. A $30,000 conversion by a couple aged 58 costs about $0 in state tax alone — Pennsylvania exempts qualified retirement income, and a conversion is a distribution from a qualified account — on top of federal tax and any ACA subsidy clawback. Pennsylvania applies one rate to all taxable income, so that state figure is the full amount before any deduction Pennsylvania allows.
