Is it possible to process an employee's bank direct deposit to her mother's bank account which is in her mother's name and not the employee's name?

I can help you in setting up your employee's direct deposit in payroll, @silkphoenix.

When setting up your employee’s direct deposit in payroll, it must be their own checking, savings, pay card, or money market accounts. Also, it should be a US bank account that is set up for ACH transactions.

After securing an account, you can now proceed in setting up direct deposit for your employee.

Go to the Payroll Tax page, then view and print the direct deposit authorization form. Allow the employee to complete the form and supply all necessary information.

Here's how:

1. Click the Taxes menu and select Payroll Tax.
2. Go to the Employee Setup and when you reach Authorization for Direct Deposit, select Bank Verification.
3. Select View and print.

Once done, proceed to the Payroll menu and enter the routing and account information from the employee's voided check. 

Check the following steps:

1. Go to the Payroll menu, select Employees and click to open the employee's name.
2. Select the Edit ✎ icon next to Pay.
3. Under How do you want to pay this employee? select how the employee wants to receive their pay. 
4. Enter the routing and account numbers from the employee's voided check and select Done.
