Explication simple

Portability can allow a surviving spouse to use a deceased spouse's unused federal exclusion, but the deceased spouse's estate generally must make a valid election on Form 706 or qualify for available relief.

A federal election that states may not follow
Portability is a federal election; state treatment may differ.
The GST exemption does not port
It does not port the deceased spouse's GST exemption.
Remarriage can change which exclusion is available
Remarriage and the identity of the last deceased spouse can matter.
Even a nontaxable estate faces a filing decision
A portability filing requires a deliberate deadline and documentation decision even for a nontaxable estate.

Approfondir

Portability lets a surviving spouse add a deceased spouse's unused exclusion to their own, but only if the first estate makes the election. The sections below cover the filing, its limits and how remarriage affects it.

Prisme fiscal

The election is made on a timely filed Form 706, and the IRS offers simplified late-election relief within five years of death for estates not otherwise required to file (Rev. Proc. 2022-32). The ported amount is fixed at the first death and is not indexed for inflation, and GST exemption does not port.

Questions sur Portability and Form 706

Does state law matter?

Usually. Document execution, probate, spousal rights, creditor rules, trust administration, and state tax treatment can vary by jurisdiction.

What should be verified before acting?

Verify the current governing instrument, title and beneficiary records, applicable state law, current tax year, primary authority, and advice from appropriately qualified professionals.
