What this guide covers
A quick view of the questions and evidence developed below.
Updated July 31, 2026. Quick answer: the year a spouse dies is usually the last year of joint filing, and the year after is where the tax bill jumps – single brackets are roughly half the joint ones, so identical income costs materially more. That transition is predictable and can be planned around. Two other things are decided in the same window and are much harder to undo. Which assets step up in basis depends on how they were titled and on whether you live in a community-property state, where both halves can step up rather than one. And a surviving spouse who rolls an inherited IRA into their own name before 59 and a half can close a penalty-free door permanently. Nothing here is urgent in week one; most of it matters before the first full tax year ends.

Remarriage changes this by operation of law: a workplace plan pays your current spouse unless that spouse signs a witnessed consent — a prenup cannot do it, and a previous spouse’s consent does not carry over. Your IRA, meanwhile, still pays whoever is on the form.
If either spouse is not a US citizen, one default fails silently: there is no unlimited marital deduction for a non-citizen spouse — the statute denies it outright, and most plans are drafted assuming otherwise. Living abroad changes the benefits side too: Social Security usually follows you and Medicare never does.
