Can I change my child's dependent status from year to year to get the best outcome?

I would like to know if I can stop claiming my child as a dependent on my 2019 taxes if it benefits him to file his own taxes specifying that he is not a dependent on anyone else's return.

 

Until now, I have claimed him - all criteria met - on my returns as a dependent, but for 2019 I wonder if he could get the 1200/- stimulus check if he were to file on his own without being our dependent. (He has a small self-employment income for 2019 for which he would have to file taxes anyway.)

 

And then revert to claiming him as a dependent in a later year if that is suitably beneficial to me?

 

Any advice on going back and forth like this on a dependent would be much appreciated. I could not find any IRS advice on this situation.

 

Thanks.
