SA109 is only available in paper form. Is it good for me to submit the SA100 and SA106 online, and submit SA109 by post? Or 3 doucments submit by post is better? Thank you very much.

You need to submit the whole return in the same format so it all needs to be online or all on paper.

You cannot use both.

You can still submit the SA109 online if you purchase 3rd party software to file your return :

Thank you.
