What is tax drag?
Tax drag is the reduction in long-term compound growth caused by taxes levied on investment returns along the way. When taxes remove part of each year's gain, less money remains invested inside the compounding engine, causing a significant difference over decades.
Which is better: Traditional or Roth?
Under identical tax rates at contribution and withdrawal, Traditional and Roth produce identical after-tax amounts. Traditional accounts provide an upfront tax deduction with taxes deferred until withdrawal; Roth accounts use after-tax contributions with tax-free qualified withdrawals. Timing and tax rate differentials determine which is more advantageous.
What makes an HSA unique?
An HSA offers a triple tax advantage for eligible individuals enrolled in a qualifying high-deductible health plan: eligible contributions can be tax-deductible or pre-tax, investment growth is tax-free inside the account, and withdrawals for qualified medical expenses are tax-free.
What is the difference between asset allocation and asset location?
Asset allocation asks what types of investments the portfolio should hold (e.g., stocks vs. bonds). Asset location asks which specific account type (taxable, tax-deferred, or tax-free) should hold each investment to minimize tax drag.
