Good morning experts!

Thank you qbteachmt for the detail information! It's really good to know you teach business class. My goal is do bookkeeping as well eventually. I want to focus on the tax season now. 

My client wants me to file S Corp extension and I will. Then she will find somebody else to fix the mess. Due to she doesn't understand English well, I cannot referral her to our community here unfortunately. 

By the way, does the S Corp need to file multi State extension? The S Corp was registered in New York in Sep 2024 but the job had done in AZ state. And she moved to AZ state since Aug 2024. The address on the 1099 NEC used her AZ address, but used S Corp' name and EIN. 

Thank you in advance!
