Why does state tax change the Roth vs Traditional math?

Traditional contributions are deductible now — in a state with income tax, that deduction saves you state tax today. But withdrawals are taxed by your state in retirement. Roth gives up that upfront state deduction but withdrawals are tax-free. The trade hinges on whether your retirement state tax rate beats your current one.

What if I retire in a no-income-tax state?

That is the strongest case for Traditional: you deduct at your current (higher) state rate now, then withdraw in a 0% state and pay no state tax on the money. Nine states have no income tax (AK, FL, NV, NH, SD, TN, TX, WA, WY). Pick your retirement state below to see the effect.

Does this include federal tax?

Yes — you enter your current and retirement federal marginal rates. The state rates come from verified 2026 data; the federal rates are your inputs. The point is to show the state-layer difference most tools miss.

Q: How is the state rate applied here?

No-income-tax states are 0%. Flat states use their statutory rate. Progressive (graduated) states use their TOP marginal rate as an upper-bound approximation for the comparison, since full brackets are not embedded.

Every generic Roth-vs-Traditional calculator ignores state tax — yet for a high-earner in California retiring in Texas, the state layer can flip the answer. This tool folds in verified 2026 state rates for both your current and retirement state.

Educational estimate, not tax advice. Both accounts receive the same annual contribution and grow at the same rate; the comparison isolates the state (and federal) tax treatment. Traditional withdrawals are taxed at your retirement state and federal rates; Roth qualified withdrawals are assumed tax-free at the state level (most states honor this; a few tax part of conversions/distributions). Graduated states use their TOP marginal rate as an upper-bound approximation. Verify with a CPA or enrolled agent. Source: Tax Foundation Facts & Figures 2026 (state rates).
