How It Works

Spanish autonomous regions set progressive wealth tax bands requiring localized rate input for personal planning accuracy. Enter portfolio value net of debts if your jurisdiction allows debt deduction against wealth tax base otherwise enter gross asset value for conservative drag estimate.

Wealth tax creates guaranteed annual headwind unlike capital gains tax triggered only on sale. Effective return equals gross return minus wealth tax rate.

Year by year table shows taxed versus untaxed ending balance path when wealth tax applies annually to beginning of year portfolio value. Compare annualized drag percentage against expected equity risk premium to judge whether wealth tax consumes most of expected market return.
Norway Switzerland and Spain apply net wealth taxes above thresholds that vary by canton or autonomous region. Model relocation scenarios by setting wealth tax rate to zero for target jurisdiction and comparing final values.

endValueTaxed = portfolioValue × (1 + effectiveReturn)^years
endValueUntaxed = portfolioValue × (1 + grossReturn)^years
totalDragDollars = endValueUntaxed - endValueTaxed
annualDragPct = (1 - (1 + effectiveReturn) / (1 + grossReturn)) × 100
