| Annual Net Tax Savings by Relocating | +$10,389 / year | ||
| 10-Year Cumulative Relocation Savings (without investment compounding) | +$103,890 | ||
Comparative Differential Formula
N-Year Cumulative Savings = Annual Savings × N
Key State Tax Limitations
- Local City and County Taxes: City and county taxes (e.g. New York City, Philadelphia, or Maryland county taxes) are not included.
- Sales & Property Tax Offsets: Zero-income tax states often fund public services with higher local property tax or state sales tax rates, which should be evaluated holistically.
- Recapture Rules: New York and Connecticut enforce statutory tax benefit recaptures at high income brackets, taxing entire incomes at top marginal rates above statutory limits.
