How Do I Update My Iowa Tax Tables?


Where do I find the tax tables?

For IA tax tables, you will need the current IA Withholding Formula and Instructions from the IA Department of Revenue.

Which tables do I use?

Use the Withholding Formula detailed on page 1 on the Witholding Formula and Instructions booklet. The images below show the relevant information to enter in PowerChurch.

Note that the figures shown in this document are for demonstration purposes only, and may not be current. Please consult the current publication for the most up-to-date information. Though the figures change periodically, the method of calculation should remain the same. If the calculation method has changed for this state please notify the webmaster.

How to setup/update the tables in PowerChurch Plus

To setup/update PowerChurch Plus with the state tax table, select the Accounting menu, Payroll, Setup, then Maintain Tax Tables. Only one table will need to be created. There was a redesign of the Iowa tax tables for tax year 2024, so you will see Iowa (Pre-2024) and Iowa (Post-2024). You will receive a warning if existing employees have the old style tables assigned on or after 01/01/2024.

Click Add to enter a new table, or use the Find/Locate buttons to select an existing IA tax table to update. When adding a new table, you will be prompted for the type of tax table you're adding. Select State: Iowa (Post 2024). For each table, enter the following information:

  • Description: Enter a unique name to identify the tax table (for example, "IA State Tax - 0 or 1").
  • Tax type: The type of tax in which this table applies. In this instance, select State Tax.
  • Standard deduction: Enter the amount for the annual standard deduction. This figure is found in a table under the computer formula instructions (see Figure 1).
