Withholding tax penalties and interest for employers

Changes to withholding tax and wage reporting take effect March 2025

The Tax Department is streamlining withholding tax and wage reporting forms and Web File applications. Beginning March 2025, these improvements will affect the way you file. For detailed information, see Significant changes coming to withholding tax and wage reporting.

We’re updating our website, publications, and other content to reflect the coming changes. To stay up to date, check back frequently or subscribe to Withholding tax emails.

  • File returns using an electronic method
  • File returns and make payments on time
  • Withhold and remit proper amount due
  • Report newly hired and rehired employees
  • Keep adequate records
  • Use the correct filing format
  • File accurate wage reports
  • Report accurate and complete withholding reconciliation information
