New freelancer: EIN use on Schedule C after using ssn

Greetings, 

My spouse and I filet tases jointly. Spouse is salaried and has a higher income. 

This year was my first year as a freelancer and sole proprietor. Not an LLC

I used my social security number on the first couple of W9s, which came from trustworthy clients. I recently got an EIN and plan to use it on W-9s with any new clients in 2025. 

 

Moving forward:

Should I complete new W9s with the EIN and send these forms to the old/trustworthy clients to let them know that I use the EIN from now on? Does it matter having a mix of W9s with ssn and eins out there? 

 

On Schedule C: should I list both my SSN and EIN? [I found so many mixed answers here.]. As I said, for the 2024 tax year, I did not use the EIN. For 2025 I'd likely have a mix of w9 forms and therefore, 1099s coming in with both ssn and eins]

 

I see that Schedule SE only requires SSN. 

 

Lastly I suspect I'd continue paying estimated social security taxes through my ssn. 

 

 

Thank you!
