Utah Withholding Settings

Current prototype uses a direct percentage less allowance reduction based on the values provided.
Formula implemented:
Withholding = max(0, round(taxableWages × rate - max(0, baseAllowance - max(0, taxableWages - threshold) × reductionRate), 2)) + added withholding

Federal Brackets

Editable annual brackets. Prototype annualizes taxable wages, applies the bracket table, subtracts per-pay dependent credit, then de-annualizes.
Filing Status Rate Low Range High Range

Wage Types

Manage wage type behavior, hourly multipliers, flat hourly add-ons, and tax treatment codes.
Category Description Hourly Rate Effect Other Hourly Amount Tax Treatment
Tax treatment codes in this prototype:
