Connecting your main bank account is not the only option when it comes to proving your sources of income.
If you have connected your account and qualify to add extra sources of income, you will see a More income needed screen. You can then select the option Upload pay stub. You can only upload alternative payslips if prompted to by this screen.
These payslips include:
Earned income (payroll/salary)
Benefits and public assistance (e.g. social security administration, unemployment assistance)
Child support
Pension
Cash or check deposits
Important to note: All payslips have a 60 day expiry window. They will "expire" 6 months after the end date of their original verified income.
