Updated July 29, 2026. Quick answer: It does not, and no state’s law changes that. IRC §1014(c) provides that the section “shall not apply to property which constitutes a right to receive an item of income in respect of a decedent under section 691.” Traditional IRAs, 401(k)s, annuities and unpaid deferred compensation are all income in respect of a decedent. Community property status is irrelevant to them.
What gets a new basis and what does not
| Asset | New basis at death? |
|---|---|
| Taxable brokerage account | Yes |
| Real estate | Yes |
| Traditional IRA or 401(k) | No — §1014(c) |
| Annuity | No |
| Unpaid deferred compensation | No |
Which reverses the usual instinct about what to spend first. If a taxable account will take a new basis at death and a traditional IRA never will, then spending the taxable account first — and preserving the IRA — wastes the one benefit death actually confers. The asset that gets forgiven is the one people are most reluctant to touch.
The partial offset, and it is genuinely partial
§691(c) allows a deduction for estate tax actually attributable to the income in respect of a decedent. Since the overwhelming majority of estates pay no estate tax at all, there is usually no such tax and therefore no deduction. The relief exists for large estates; for everyone else it is nothing.
This is also why a community property double step-up is worth so much less to a household whose wealth sits mostly in retirement accounts than to one holding a large taxable portfolio.
