You may protest a claim by completing and returning the "Notice to Employer" (UB-110) (view UB-110 Sample 105 KB PDF) within 10 working days of the date of the notice. This notice indicates whether the claimant identified you as the last employer prior to filing the claim or you are considered a base period employer. You may receive and respond to the “Notice to Employer” by paper-based mail or, if you sign up for the UI State Information Data Exchange System (UI SIDES) or SIDES E-Response, you may receive and respond to it electronically. A telephone call to the benefit claims office does not constitute a valid protest; it does not exempt you from the necessity of completing and returning the "Notice to Employer."
To protect your rights, return the "Notice to Employer" (UB-110)
within 10 working days.
Any Employer (including reimbursement employers) should return the "Notice to Employer" if:
1. The claimant named on the notice was not your employee, or
2. You have information that the claimant is not willing or able to seek and accept suitable work, or
3. You have work available and want to offer the claimant employment.
If you are a Last Employer and wish to protest a claim, see Determining Eligibility for Unemployment Benefits.
Base Period Employers
If you are a Base Period Employer, you should complete and return the "Notice to Employer" within 10 working days if the claimant voluntarily left your employment or was dismissed for a reason other than lack of work. (Reimbursement base period employers need not return the notice under these circumstances. This is because by law, the relief of charges discussed below does not apply to them. Arizona Revised Statutes § 23-750(B)(4) and Arizona Administrative Code § R6-3-1717(A)).
As a Base Period Employer, the claimant's reason for separation from your employment determines whether your account will be charged for its proportionate share of any benefits paid to the claimant. It does not affect the claimant's current entitlement to benefits. If your account is to be charged, the amount of taxes you have paid on your unemployment tax account will be reduced by your share of the benefits paid to the claimant. If your account is not charged, no reduction in the balance of taxes in your unemployment account will be made. (Benefit charges are one of several factors that can potentially increase your tax rate in future calendar years.)
Specific information concerning the claimant's current availability for work or ability to work (e.g., the claimant is currently a full-time student) may postpone the claimant's receipt of benefits but will not relieve you of charges to your unemployment account if the claimant later qualifies for benefits.
