Why it matters in retirement

Fewer than 0.1% of estates owe federal estate tax — but the step-up in basis affects everyone. For most retirees, the biggest estate-planning decision isn't taxes, it's beneficiary designations and whether to use trusts to simplify inheritance and protect assets.

Pros
  • Step-up in basis eliminates capital gains at death
  • Exemption portable between spouses
  • Charitable bequests fully deductible
Cons
  • State estate tax thresholds can be much lower
  • Future law can change exemption amounts
  • Trust planning adds complexity
  • Portability must be elected

Common mistakes

  • Skipping portability election at first spouse's death
  • Ignoring state estate tax in states like MA, OR, NY
  • Leaving IRAs to an estate instead of named beneficiaries
  • Assuming the federal exemption will always be this high
The part most people miss

The step-up in basis at death means appreciated stock inherited by a beneficiary resets to fair market value on the date of death — potentially saving six figures in capital gains tax. This is why "never sell your most appreciated shares" is common retirement advice.
