Kentucky employers prepare for Aug. 17 unemployment tax-portal launch after TPA deadline
Kentucky’s final deadline for third-party administrators seeking automatic account setup has passed, and the state’s new unemployment-insurance tax portal is scheduled to launch Monday, Aug. 17, 2026.
The Kentucky Unemployment Insurance Portal, or KUIP, will move employer tax functions from the legacy Kentucky Employer Web-based Employer Services system, known as KEWES. Employers and TPAs should prepare for new credentials, updated employer identification numbers and additional transition deadlines.
What changes Aug. 17
After the scheduled Tax-phase launch, employers and TPAs will use KUIP for wage filing, electronic payments, viewing charge statements and maintaining employer accounts. Kentucky previously targeted May 2026 for the Tax phase but moved the launch to Aug. 17, citing the need for additional time for system stability, data integrity and user preparation.
Existing employers will receive an eight-digit account activation code and a new nine-digit Kentucky Employer Identification Number, or KEIN. The state says those credentials will be sent by mail to the employer’s physical address and displayed in KEWES through a pop-up message.
To activate the existing business account in KUIP, an employer will need its Federal Employer Identification Number, or FEIN, the new nine-digit KEIN and the eight-digit activation code. The employer must then create a new KUIP user account, username and password. Existing employers do not need to re-register the underlying business account, but their legacy login will not simply transfer.
What TPAs need to know
The final passive-role-assignment submission window for TPAs ran from July 13 through Aug. 3. Kentucky says there will be no additional submission opportunity.
Passive role assignment was an optional, one-time process intended to create TPA accounts, assign TPA IDs and establish existing TPA-employer relationships before go-live. The Aug. 3 deadline applied to TPAs seeking that automatic setup; it does not mean every TPA failed to meet a requirement.
TPAs that did not participate, or whose submission was not accepted, must register in KUIP after launch and request authorization from each client employer. Before a TPA can be authorized, it must register and receive a TPA ID.
A TPA can request access by entering the employer’s KEIN and FEIN. The employer will be notified according to its selected contact method and will have 14 calendar days to approve or deny the request. If the employer does not respond within that period, the TPA will automatically receive the requested access.
Employers included in an accepted passive-assignment submission still must activate their KUIP accounts. The state’s guidance says passive assignment can establish selected TPA-employer relationships before launch, but TPAs may not perform functions beyond the roles and permissions assigned or authorized.
Legacy-system deadlines
Several KEWES employer and TPA functions closed at the end of business on Aug. 3. That deadline covered second-quarter 2026 wage and tax reports, electronic payments, employer, TPA and PEO registrations, and account-close requests.
As of Aug. 4, two listed deadlines remain:
- Aug. 10: Address changes must be completed.
- Aug. 12: IRS recertification requests must be submitted.
The state also has published updated wage-file guidance. KUIP will use revised ICESA specifications and will accept a CSV file format. Employers and TPAs should review the specifications before submitting reports through the new portal.
Benefits are not moving on Aug. 17
The Aug. 17 change is primarily an employer tax-system transition. During the bridging period, Kentucky says benefits-related functions such as fact-finding, claims-related correspondence and appeals filing will continue in legacy systems.
Claimants should continue using KEWES and other instructions from the Office of Unemployment Insurance for benefits-related activity. Kentucky’s modernization project has two phases, with the Benefits and Appeals phase expected to launch in 2028. The Aug. 17 date is a scheduled Tax-phase launch, not a completed transition of every unemployment service.
What Kentucky businesses should do now
- Watch the company’s physical mail and KEWES messages for the activation code and new KEIN.
- Plan to create a new KUIP username and password on or after Aug. 17.
- Confirm whether the company’s TPA was included in an accepted passive-role-assignment submission.
- If post-launch authorization will be needed, coordinate with the TPA and respond promptly to KUIP requests.
- Complete address changes by Aug. 10 and IRS recertification requests by Aug. 12.
- Review the revised ICESA and CSV wage-file specifications.
- Use the state’s employer and TPA training resources before the first filing or payment through KUIP.
Kentucky’s Office of Unemployment Insurance has scheduled webinars for employers and TPAs covering registration, account maintenance, wage reporting and payments before and after the planned launch.
