REGISTERING FOR UNEMPLOYMENT INSURANCE

If you've never run payroll in New Mexico before, you'll need to register with the New Mexico Department of Workforce Solutions by completing the online registration .

Once registered, you will receive an Unemployment Account Number (UI) (called Employer Account Number) and Unemployment Rate (%) which you will need to enter into Namely Payroll under Company > Tax screen (UI tax). 

If you've run payroll in New Mexico in the past, you can find your Employer Account Number on notices received from the New Mexico Department of Workforce Solutions such as the Quarterly Wage and Contribution Report. 

 

REGISTERING FOR INCOME TAX WITHHOLDING

If this is your first time running payroll in New Mexico, you'll need to register with the New Mexico Taxation and Revenue Department by completing the online registration. 

Once registered, you'll receive a Withholding Tax Account Number (WH), which you'll need to enter into Namely Payroll under Company > Tax screen (WH tax).

If you've run payroll in New Mexico in the past, you can find your CRS Identification Number on Form CRS-1 and other notices received from the New Mexico Taxation and Revenue Department. 


Out of State Tax Withholding

If you have an employee move mid-year to a new state, the Namely Payroll system will automatically apply a SUI Reciprocity Wage Credit for the taxable wages accrued in the first state when appropriate. This means the employee will not pay taxes up to the full wage limit for this employee in the second or subsequent states. 

Several states do require reporting on their quarterly unemployment returns when taking a Reciprocity Wage Credit for an employee. In these cases, Namely will automatically handle the Out-of-State Wage reporting requirement on your behalf. However, New Mexico requires an additional form to be filed by you, outside of the quarterly unemployment returns. Namely will not handle this reporting requirement. You will need to fill out this PDF form for any employees where you have taken a credit due to prior YTD Out-of-State Wages.

 

POWER OF ATTORNEY FORMS

Please note, Namely does not require a Power of Attorney for this state at this time. It is not required to file or remit payments on your behalf. If one is needed to resolve a tax matter, the tax notice team will request one from you at that time.

If a Power of Attorney is requested from you, you should email completed copies of the forms namelyPOA@Namely.com with the CID in the subject line for processing. We will update our system and maintain a copy of each form for record-keeping purposes

For additional information on Power of Attorney, read Completing the Power of Attorney Package.
