Same as it would if they were a resident of CA, but the 541 isnt available until mid January, is this a 2024 return? 

Make sure youve got the CA 1041 module set for install in  UPDATE > Select and Download New Products so it will install once its ready.

Inside the CA 541 there is (will be) a grid for sourcing the CA source income (and the residency of fiduciaries and beneficiaries).  I'm assuming you're filing in CA because the trust has CA source income (e.g., owns rental properties)?

And if not already, be aware of the accumulation distribution rules in CA together with 'CA expat' rules.  There are also recent cases regarding residency of (contingent) beneficiaries, etc.  Link below is old and should be updated but it might give you some background info that might be helpful.

Thanks for the information.  However, are you sure that ProSeries is going to provide a 541 by mid-January, or at all?  I don't see it in the list of available states' 541 returns.  All I see is form 1041 but nothing for California 541.

It says it should be ready by 1/23  Be sure youve got CA checked under the 1041 in the Download and Select New Products window under Update on the top menu bar

Release Dates

OK.  Thank you for the prompt reply.  I will watch for the 541 to become available.
