Can I submit my tax documents separately after submitting my visa application to the Los Angeles Consulate?

Just submitted to Los Angeles Consulate and I was trying to add my tax documents (CA state income + federal) along with my bank statement but even after compressing many times the files were still way too big (if I kept compressing it the quality would be awful) so I submitted the application only with bank statement without the tax documents.

Can I submit them separately or just have to wait until they request it?

Will this delay my application if they ask for them later or should I be ok without them? My flight out date is Jan 12 so I'm hoping it won't push it back or delay too far from now.
