Tax drag, RMD, and IRMAA by location
How state tax policy, RMD timing, and IRMAA shape after-tax income throughout retirement.
Key takeaways
- • State top marginal rates and pension treatment shift net income; we capture these in tax_adjust.
- • RMD and IRMAA timing can spike taxes and premiums; location changes how much it hurts.
- • Withdrawal sequencing (taxable, traditional, Roth) interacts with state policy over decades.
Deep dive
Taxes, RMD timing, and IRMAA shape your after-tax income. Location matters for net withdrawals over decades.
Your score starts with state marginal burden as a proxy and expands to retirement-specific treatments as public data allows.
Signals we consider
- • Your score starts with top marginal rates as a proxy and expands to pension treatment/credits as data is added.
- • Federal overlays: RMD and IRMAA timing can spike taxes/premiums.
- • Sequencing: Withdrawal order interacts with state policy across years.
How it enters the score
- Federal + state tax drag: Combined marginal rates and phaseouts influence after-tax withdrawals and cash flow.
- RMD timing and size: Required minimum distributions can push you into higher brackets or trigger surcharges.
- IRMAA exposure: Income-related Medicare adjustments increase healthcare costs at certain thresholds.
- Withdrawal sequencing: Order of withdrawals (taxable, tax-deferred, Roth) changes lifetime tax burden.
- Location differences: State and local tax rules (pension exemptions, property tax, sales tax) alter long-run drag.
Data sources
- • IRS federal brackets, RMD tables, and IRMAA thresholds
- • State tax policy data (income, pension treatment, property tax context)
- • Location-driven cost inputs that affect withdrawal needs
Action checklist
Use these steps to turn this explainer into practical planning decisions.
- • Review projected bracket exposure for your first 10 retirement years.
- • Identify RMD and IRMAA threshold years where income spikes may occur.
- • Test at least one alternative withdrawal sequence for tax efficiency.
- • Compare state-level net income impact before making a relocation decision.
