Wife collects SSI Disability, I am her fulltime care giver, we have 2 children. I was told to file married filing separately in order to claim the stimulus, what do I do?

obtaining the stimulus should have nothing to do with whether you file married-joint or separate. 

filing separate could cost a lot more in tax because there are often benefits you lose by filing separate 

unless you get that advise from a qualified tax professional and he/ she gives you valid reasons for it, I would not follow it

She collects SSI/Disability and should be receiving her stimulus through SSI, I do not work and stay home due to the amount of care.  I do not get paid, the people at SSI said they were not sure how to file, other than married filing separately since she would be receiving a check through them.

@legionexus -  did you file in 2018 or 2019? I am confused because you state you do not work

are you required to file in 2018 or 2019?

based on your response, I can suggest a path forward 

[legionexus]

@NCpersonI haven't had to file since 2017, I had to quit work to take care of my wife since then.

then all yo have to do is file as a non-filer / single 

there is no married-separate designation and your spouse should get the stimulus later this week
