Iowa did WHAT!?
For the first time since 2006, Iowa has changed the withholding tables. The changes are designed to align with recent changes in the state tax laws. Use the link below to see the most current withholding tax tables. There are different tables based on your pay frequency. For example, if you are paid every other week you would want to choose the bi-weekly table. If you are paid two times a month (e.g. the 5th and 20th) then you will want the semi-monthly table. These new tables were effective January 1, 2019. Employers should have automatically changed to the 2019 withholding amounts but employees can make changes to their Iowa W-4 forms by contacting their employer.
Note: If you are using a payroll software for your payroll then these tables should have been updated with your payroll subscription but you can access these tables in order to verify.
