Employers - Instructions, Forms, Calculator

Withholding the Multnomah County Personal Income Tax for your employees is a great service. It provides employees with the security of knowing they will not have a surprise tax bill at the end of the year. Also, employer withholding ensures the funds reach their intended destinations as soon as possible: schools, health and safety services.

Tax year 2005 is the last year of the Multnomah County Income Tax.

Employer reminders for the final year of the tax:

  • Any tax withheld from employees' wages for the quarter ending December 31, 2005 must be remitted to the ITAX Administration by January 31, 2006.
  • Starting January 1, 2006, employers should not withhold any ITAX from employees' wages.
  • Annual Withholding Tax Reconciliation Reports and Employee Withholding Schedules for tax year 2005 (Form MCWR 2005) are due no later than March 31, 2006.

Please note: If you are a payroll service filing on behalf of more than one Multnomah County employer or an employer with more than 50 employees, you must submit the data required on the Form MCWR in a standard electronic format. Please see our website for electronic format options and specifications.
