Im not sure they really care, as long as they get their money...it might be one of the umpteen questions on the 568, they will all flag red until you answer them all.   

If you check the box at the top of the Sch C, that its a CA SMLLC it will transfer the info over to the 568 for you.

Concise, accurate and correct. Deserves high accolades, like SOLVED!

Thanks Lisa but it is related out-of state LLC while we file 568. 

He registered as a foreign LLC with the CA secretary of state, like he should since he's doing business in CA and the LLC was formed somewhere else.   

Do they issue a state ID number for SMLLCs (I cant remember)?  If they did, that would go on the 568 as well as the Federal EIN.

Read through that long list of questions on the 568, it may be one of those questions, in the grand scheme of things, I don't think it matters to FTB where he came from, as long as he files a return and they get their money.

I think you may want to file Colorado. Do some research at https://tax.colorado.gov/business-income-tax   and https://tax.colorado.gov/sites/tax/files/Income%20Tax%20Nexus%20Soliciting%20Sales%20General%20Infor...

I know CA would come after a CA LLC. regardless of where they are. 

Thanks
