Having your Oregon WBF tax to calculate correctly is my priority. Let's get this sorted out.
QuickBooks will calculate taxes based on the information and hours that you've entered on the earnings section of your employees' paycheck. To learn more about the Oregon WBF tax calculation, you may refer to this article: Set up or change Oregon Worker Benefit Fund (OR WBF).
Also, It'd be best running a payroll update every time you do payroll for your employees to ensure that your tax table is updated to the latest release.
To do that:
Go to the Employees menu, then select Get Payroll Updates.
Put a check in the Download Entire Update checkbox.
Allow me to provide additional clarifications about fixing your Oregon WBF tax calculation.
If you want to exclude the holiday pay to be included in the taxability of Oregon WBF, this option isn't available for us. This is because QuickBooks tax calculation will depend on the item type. Since a holiday pay is a compensation, automatically it will be added as taxable.
In situations like this, I'd suggest reaching out to your accountant to ensure the best course of action for your business.
Let me know if you have any other questions. I'll make sure your taken care of.
