Filing status from your W-4 form
Number of dependents and credits claimed
Pay frequency (weekly, biweekly, etc.)
Gross pay per period
Pre-tax deductions (401k, health insurance)

Frequently Asked Questions
Common questions about federal tax withholding
What is a W-4 form and why does it matter? −
The W-4 (Employee's Withholding Certificate) is a form you fill out when starting a new job. It tells your employer how much federal income tax to withhold from your paycheck. The 2020 redesign eliminated allowances and instead uses filing status, multiple jobs adjustments, dependent credits, and additional withholding amounts to calculate your withholding.
What happened to withholding allowances? +
The IRS eliminated withholding allowances starting with the 2020 W-4 form. Previously, each allowance reduced your taxable income by a fixed amount. The new W-4 uses a more straightforward approach based on your expected filing status, income from multiple jobs, dependent tax credits, and any additional amounts you want withheld. If you filed a W-4 before 2020, your employer will continue using your old allowances until you submit a new form.
How can I reduce my federal tax withholding? +
You can reduce your withholding by: contributing to a pre-tax 401(k) or traditional IRA, claiming eligible dependent credits on your W-4, using the married filing jointly status if applicable, and contributing to a Health Savings Account (HSA) or Flexible Spending Account (FSA). Be careful not to under-withhold, as you may owe taxes and penalties when you file your return.
When should I update my W-4? +
You should update your W-4 after any major life event: getting married or divorced, having a child, buying a home, starting a second job, or if your spouse starts or stops working. The IRS also recommends an annual checkup using their Tax Withholding Estimator. If you received a large refund or owed taxes at filing time, adjusting your W-4 can help you get closer to the right withholding amount.
