How does a freelancer prove their income to the bank?

Freelancers can prove their income in several ways, depending on the bank, such as bank statements showing regular transfers, contracts or invoices, tax documents, or any official document that clarifies the nature of their business and income.

There isn't one specific document required by all banks, so prepare multiple forms of proof of your work and income.
