State Form MO W-3

Employer’s Annual Information Return of income Taxes Withheld

The MO W-3, “Employer’s Annual Information Return of Income Taxes Withheld”, is a form used by employers in the state of Missouri. It serves several primary functions:  

Annual Reconciliation 

The MO W-3 provides the Missouri Department of Revenue with a summary of the total state income tax that an employer has withheld from its employees’ wages throughout the calendar year. This form ensures that the amounts reported on the individual wage statements (usually the W-2 forms) align with the total tax withheld and remitted to the state. 

Submission of Wage Statements 

Along with the MO W-3, employers are required to submit copies of the W-2 forms (or equivalent wage statements) issued to their employees. This ensures the state has a record of individual wage and tax information for each employee. 

Compliance with State Tax Laws 

Filing the MO W-3 is part of fulfilling an employer’s obligations under Missouri’s tax laws. Not filing or incorrectly filing can result in penalties and interest. 

Reference for Employees 

By reconciling withheld taxes and reporting them to the state, the Department of Revenue can verify and cross-check information when employees file their individual state tax returns. 

It’s essential to file the MO W-3 to remain in compliance with state’s tax laws and regulations when you’ve made payments that require information returns and have had Missouri income tax withheld. Not filing or late filing can lead to penalties and interest charges.
