Depositing and Reporting Withheld Taxes: Missouri
Federal law and guidance on this subject should be reviewed together with this section.
- Four different income tax deposit and filing frequencies apply in Missouri: quarter-monthly, monthly, quarterly, and annually. An employer's status depends on how much it withheld during certain time periods. See Deposit and Filing Requirements.
- An employer may use the paper forms provided in its voucher booklet to file its returns, or it may file returns electronically using various options available on the Department of Revenue's website. Employers must file a return even if there is no payroll for the reporting period or the employer did not withhold any tax. See Forms.
- Missouri employers that file 250 or more Forms W-2, Wage and Tax Statement, must file them on magnetic media along with a transmittal form. See Annual Reconciliation Forms and Filing Requirements; Electronic and Magnetic Media Form W-2 Reporting Requirements.
- Penalties apply to Missouri employers that do not timely file withholding tax returns and/or do not make payments when required. See Penalties.
