Hi SethL,

To add the employee's current address as their work location, here's how:

1. Go to the Gear > Payroll Settings.
2. Under Business Information, click the Work Location link.
3. Select the Add a Work Location link.
4. Enter the employee's current address and click Save.

Once done, select the address on the employee's setup.

1. On the left panel, click Workers > Employees.
2. Select the employee's name, and click the pencil icon next to Employment.
3. Choose the work location you just created from the Work Location drop-down.
4. Click Done.

With regard to the multistate situation, I'd recommend consulting with your accountant or tax advisor to make sure your payroll reports are accurate. I've got this article for more information: Multistate situations
