$124,740 difference over 30 yearsFor an identical retiree (age 60, $2M, 60/40, $80K real spend), QuantCalc's Monte Carlo study found a median 30-year state-tax gap of $124,740 between Oregon and Nevada — Nevada is the cheaper state. That money stays invested, which is why Nevada's median terminal balance is higher.

The income-tax difference, year by year
The simplest way to see the gap: on a steady $100,000 annual retirement withdrawal, Oregon collects about $9,900 in state income tax and Nevada collects about $0 — a difference of roughly $9,900 every year. 9.9% top rate over $125k single, no sales tax, $1m estate exemption (one of lowest). No state income tax, no estate tax, sales tax 6.85%.
Over a 30-year retirement, QuantCalc's Monte Carlo simulation (identical portfolio and spending in both states, only the tax code changes) puts the median lifetime state-tax difference at $124,740 — and because the saved tax stays invested and compounds, Nevada's median ending balance is the higher of the two.
Beyond income tax
State income tax is only part of the retirement-cost picture. When comparing Oregon and Nevada, also weigh:
- Property tax — a tax-free-income state can still have high property tax; factor your home value.
- Sales tax — affects every dollar you spend, not just income.
- Estate / inheritance tax — Oregon: has one; Nevada: none. Matters for larger estates.
- Roth conversion cost — converting in the lower-income-tax state of the two cuts the state tax on each converted dollar. See conversion-tax scenarios.
