As for the bank statements — very unlikely (but each application is unique so take that with a grain of salt). I wasn’t asked for bank statements. Only tax assessments because visa offers can estimate our monthly income from that alone. The basically ignored my invoices and bank statements.

Regarding minimum income — again it can vary. You should check what’s considered the minimum where you live. Obviously, this will be different from the monthly estimates we use for a student visa. They want to be confident that you’re earning an adult size paycheck from your business.
