What Form IA 12.3 Is For
Form IA 12.3, Record of Employment, is the official separation notice that New York State employers must provide to workers when their employment status changes. Administered by the New York State Department of Labor's Unemployment Insurance Division, this single-page certificate serves as written documentation that an employee's job was covered under the state's Unemployment Insurance program. The form contains critical employer information—including the New York State Employer Registration Number, Federal Employer Identification Number, and the address where payroll records are kept—that helps streamline the unemployment claims process and ensures accurate benefit administration.
This is not a tax form or benefits application. Rather, it functions as an informational bridge between employer, employee, and the Department of Labor. When workers receive this certificate, they gain immediate access to essential details they'll need if they choose to file for Unemployment Insurance benefits. The form itself does not determine eligibility or guarantee that benefits will be granted; only the Unemployment Insurance Claims Center makes that determination after reviewing a complete application.
When You’d Use Form IA 12.3
Standard situations requiring the form:
- Permanent layoffs or indefinite layoffs
- Temporary layoffs or furloughs
- Discharge or termination for any reason
- Voluntary resignation or quitting
- Reduction in weekly hours to 30 or fewer
- Any interruption of continued employment resulting in total or partial unemployment
Partial unemployment trigger
As of 2023, New York expanded employer obligations beyond traditional separations. Employers must now issue Form IA 12.3 when an employee's hours are reduced below the partial unemployment threshold—working 30 hours or fewer per week OR earning less than the maximum benefit rate per week (the maximum benefit rate changes annually and can be found on the Department of Labor website).
Late filing considerations
Unlike quarterly tax forms that have specific deadlines, Form IA 12.3 must be provided at the time of separation or hour reduction. There is no formal "late filing" procedure, but failure to provide the form when required can result in delayed notices from the Department of Labor, inaccurate experience rating charges to your employer account, and potential complications in unemployment claims processing. If you realize you failed to provide the form, issue it immediately—employees may still file claims successfully, but having the form ensures smoother processing.
Amended situations
Form IA 12.3 itself is not "amended" in the traditional sense. However, if employer information changes after you've provided the form (such as a change in the address where payroll records are kept), you should use Form IA 15 (Change of Business Information) to update the Department of Labor directly. If an employee was given incorrect employer registration numbers or addresses on their Form IA 12.3, provide a corrected copy promptly to prevent processing delays if they file a claim.
