Why taxes matter in retirement
Taxes reduce the income available for living expenses and may affect Medicare premiums, Social Security taxation, and the Net Investment Income Tax (NIIT). Being deliberate about where you hold assets and how you realize gains or losses may improve after-tax outcomes depending on individual circumstances.
Mistake 1 — Putting tax-inefficient assets in taxable (brokerage) accounts
Putting assets that generate ordinary interest in a taxable brokerage account may result in higher taxable income and impact after-tax returns.
- Corporate and many government bond interest is taxed as ordinary income (higher rates compared to long-term capital gains rates) maybe a poor fit for taxable accounts.
- By contrast, qualified dividends and long-term capital gains often get preferential long-term capital gains rates (0%, 15%, or 20%), which are usually lower than ordinary income tax rates.
Table: Typical tax treatment by asset type
| Asset | Typical Tax Treatment in a Taxable Account |
|---|---|
| Corporate bond interest | Ordinary income tax rates |
| Treasury interest | Ordinary income tax rates (federal taxable; state may differ) |
| Unqualified dividends | Ordinary income tax rates |
| Qualified dividends | Long-term capital gains rates |
| Long-term capital gains | Long-term capital gains rates |
Practical Ways Investors May Improve Tax Efficiency:
- Some investors choose to hold tax-inefficient fixed income in tax-advantaged accounts, depending on their goals and tax profile.
- Tax-efficient holdings, including broadly diversified equity index funds or tax-managed funds, are often placed in taxable accounts because long-term capital gains and qualified dividends may receive favorable tax treatment.
- Rebalancing may be approached with tax awareness, such as realizing gains in lower-income years or using tax-loss harvesting when applicable.
Mistake 2 — Putting municipal bonds in retirement accounts
Many municipal bonds generate interest that is exempt from federal income tax — one of their core benefits. Placing these tax-exempt assets inside tax-deferred accounts may negate that benefit.
Why this is costly:
- Withdrawals from most tax-deferred accounts are generally taxed as ordinary income, which may include interest that would have otherwise been tax-exempt.
Practical considerations:
- Some investors prefer to hold federally tax-exempt municipal bonds in taxable accounts to maintain their tax-exempt characteristics, depending on their individual situation.
- Reviewing tax-equivalent yield calculations can help investors compare municipal and taxable bond yields when evaluating potential account placement.
Example — tax-equivalent yield for muni vs corporate bond
If a municipal bond yields 3.5% tax-free, and your federal marginal tax rate is 24%, the tax-equivalent yield = 3.5% / (1 - 0.24) = 4.61%. This hypothetical example is for illustration only and actual results depend on an investor’s tax profile and specific investments.
Mistake 3 — Not understanding tax-loss harvesting properly
Tax-loss harvesting may be a useful strategy, but misunderstandings (or ignoring rules) may reduce its benefits.
How it works (brief):
- Sell an investment at a loss to realize a capital loss.
- Realized capital losses offset realized capital gains. Excess losses offset up to $3,000 of ordinary income per year, with the remainder carrying forward.
- Be mindful of the wash-sale rule (disallows a loss if you buy a “substantially identical” security within 30 days before or after the sale).
Common traps and tips:
- Replacing a sold position with a nearly identical ETF or fund that triggers a wash sale can invalidate the loss — use a suitable replacement (different fund with similar exposure) or wait 31+ days.
Tax-loss harvesting should be considered alongside an investor’s overall asset allocation and risk tolerance.
Quick action checklist for retirees
- Inventory — list current holdings by account type (taxable vs tax-deferred vs Roth).
- Map — classify each holding as tax-efficient (equities, qualified dividends), tax-inefficient (ordinary interest), or tax-exempt (munis).
- Reposition — review whether certain assets may be more tax-efficient in different account types based on your broader financial plan.
- Harvest — review opportunities for tax-loss harvesting while respecting wash-sale rules.
- Coordinate — consider timing of Roth conversions and distributions as part of overall tax planning.
