How will changing state withholding to married filing jointly with one spouse working affect state taxes?

[roger321]

in Georgia you have an option to claim married filed jointly with both, or one spouse working. we are currently claiming both spouses working, but would like to know whether changing it to one spouse working would withhold more or less from my wife's state taxes on her paycheck

[Critter · Accepted solution]

They will withhold less which may mean you are underwithheld and will owe at the end of the year.

I’m currently not working, but will start receiving SS in October 2019. Same answer?

Then you will not need withholding on 2 wages any longer and GA doesn't tax SS benefits.
