Why tax drag deserves attention

A retirement spending plan that looks comfortable before taxes can feel much tighter once income taxes are considered. Tax drag can also change how large a portfolio really needs to be.

A tax rate in this range is typical of a retiree whose taxable income sits in a lower bracket, whether from a smaller withdrawal, tax-advantaged account mix, or lower non-retirement income.

A longer retirement horizon raises the stakes of tax-aware planning, since small differences in the effective tax rate compound across many more years of withdrawals.

Limits of this simplified example

The model uses one assumed tax rate, not a full tax return or account-order withdrawal strategy.

Real-world retirement taxes depend on filing status, deductions, account types, Social Security taxation, state taxes, and changing tax brackets.
