Steps to Calculate Withholding Tax
Step 1: Assemble Essential Paperwork
Begin by gathering all the necessary paperwork to assess the federal income tax withholding amount. Ensure you have the following items:
- W-4 forms completed by employees
- Each employee’s gross earnings for the given pay period
- IRS income tax withholding tables (found in IRS Publication 15-T)
- The tax calculator for the current year
2. Review Employee W-4 Forms
Verify that you have the correct W-4 forms for your employees. These forms contain key information for federal income tax withholding calculations, including filing status, tax credits for dependents, additional income sources, and any extra amounts employees request to be withheld. Significant life changes such as marriage, divorce, or having children can affect an employee’s withholding requirements, so it’s advisable for employees to review and possibly update their W-4 forms when their circumstances change.
3. Examine Payroll Data
Gather data from your payroll system to calculate federal tax withholding. This will require:
- Specifics about the payroll period, including how often the pay periods occur (whether weekly, biweekly, semi-monthly, or monthly) and the length of each period
- Total earnings for the pay period for each employee, which is the gross amount before any deductions
4. Select a Calculation Method
After gathering all necessary W-4 and payroll information, choose a calculation method. There are two options:
Wage Bracket Method
The simplest method involves using IRS income tax withholding tables to identify each employee’s wage range. Instructions and tables are available in IRS Publication 15-T.
Percentage Method
A more complex approach, the percentage method also has instructions in IRS Publication 15-T, differing based on whether you use automated payroll software or a manual payroll system. This method requires careful calculation, including factoring in tax credits and determining the final withholding amount.
Remember, these instructions cover only federal income tax withholding. Depending on employee location, you may also need to account for state and local income taxes. Additionally, employers must withhold Federal Insurance Contributions Act (FICA) taxes, which include Social Security and Medicare.
What are Withholding Allowances?
Before 2020, withholding allowances were used as personal and dependency exemptions to reduce the income tax deducted from an employee’s paycheck. Employees would claim these allowances on Form W-4, and the more allowances they claimed, the less federal tax their employer would withhold.
However, the new Form W-4 no longer includes withholding allowances. Instead, it has been updated to include four steps that provide the necessary information to determine the appropriate amount of tax to withhold from an employee’s paycheck. These steps include specifying the employee’s filing status, the number of jobs held concurrently, tax credits for dependents, and any extra amounts that need to be withheld. Employees can also utilize the IRS’s Tax Withholding Estimator tool to see how their withholding choices impact their take-home pay.
Income Tax Rates for 2023 and 2024
Tax liability is incurred when you earn taxable income. This is your gross income minus any allowable tax deductions. When reviewing your income tax returns, it’s essential to know which income tax rate applies to you. Federal income tax rates are segmented into the following tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. These rates apply to taxes due in April 2023 or April 2024.
For individuals filing under single, married filing jointly, married filing separately, or head of household status, the federal income tax brackets and rates for the 2023 tax year are as follows:
