Can a spouse be a dependant married filing jointly?

It is my understanding the spouse qualifies except having same social security number

Dependents are either a qualifying child or a qualifying relative of the taxpayer. The taxpayer's spouse cannot be claimed as a dependent.

A spouse can NEVER be claimed as a dependent.  File a joint return.  You can file a joint return even if one spouse has little or no income.

If you were legally married at the end of 2023 your filing choices are married filing jointly or married filing separately.

Married Filing Jointly is usually better, even if one spouse had little or no income. When you file a joint return, you and your spouse will get the married filing jointly standard deduction of $27,700 (+$1500 for each spouse 65 or older)  You are eligible for more credits including education credits, earned income credit, child and dependent care credit, and a larger income limit to receive the child tax credit.
