How are married couples affected, if only one spouse has a Social Security number?

As with EIP2, joint filers where only one spouse has a Social Security number (SSN) will normally get the third payment. This means that these families will now get a payment covering any family member who has a work-eligible SSN.

For taxpayers who file jointly with their spouse and only one individual has a valid SSN, the spouse with a valid SSN will receive up to a $1,400 third payment and up to $1,400 for each qualifying dependent claimed on the 2020 tax return.

Active Military: If either spouse is an active member of the U.S. Armed Forces at any time during the taxable year, only one spouse needs to have a valid SSN for the couple to receive up to $2,800 for themselves in the third stimulus payment.
