What is lst on w2?

The box labeled "lst" on a W-2 form refers to the amount of money withheld from an employee's paycheck for state and local taxes. This includes state income tax, local income tax, and in some cases, state disability insurance and unemployment tax. The amount listed in the lst box represents the total of all state and local taxes withheld from the employee's pay throughout the year and is used to determine the employee's tax liability for the year. The amount is also reported to the state and local tax authorities for tax reporting purposes.
