Reciprocal agreements between states allow employees that work in one state but live in another to only pay income taxes to their state of residency (home state).
If reciprocity exists between the two states, employees will need to complete and deliver a non-residency certificate to you in order to have residency state tax withheld instead of the work state tax.
While reciprocity is determined by an employee's home address and pertains to their income tax withheld, unemployment liability is typically determined by an employee's work address.
Before registering for unemployment tax in a new state, please reach out to an accountant or the applicable state agency for determination of liability.

Note: NY and NJ do not have reciprocity. If you work in NY and live in NJ, you will need to pay NY income taxes as a non-resident and pay NJ income taxes as a resident. However, NJ residents can take a tax credit for taxes that have been paid to other jurisdictions.
Step 1. Register for a withholding ID with the resident state
If your employee's resident state already exists in your Gusto account with a withholding ID, you don't need to complete step one.
Step 2. Receive a signed Certificate of Nonresidency
Step 3. Elect to withhold income taxes in the resident state
Step 4. Enter a withholding ID for the resident state
If your employee's resident state already exists in your Gusto account with a withholding ID, you don't need to complete this step.
Income tax withholding requirements vary by state.
Gusto does not support flexible (variable) courtesy withholding*—for now, there are safeguards in place to make sure that the required payroll taxes, both unemployment taxes and income withholding taxes, are calculated and withheld based on the applicable address(es) on file for employees during the work period you pay them for.
*Exception: courtesy withholding is supported for employees who work in Idaho, and live in either Washington or Wyoming.
