Guide to Fill Up your W4
Filling out a W-4 form correctly ensures the proper amount of federal income tax is withheld from your paycheck. Below is a guide for Single and Married Filing Jointly statuses:
Step-by-Step Guide to Filling Out the W-4
Step 1: Enter Personal Information
Provide your name, Social Security Number (SSN), and address.
Indicate your filing status:
Check Single or Married Filing Separately if you're single or filing separately.
Check Married Filing Jointly if you and your spouse file jointly.
Step 2: Multiple Jobs or Spouse Works (if applicable)
If you have more than one job or your spouse works, complete this step. Use only one W-4 for the highest-paying job to get accurate withholding.
Options to complete:
Use the IRS's Tax Withholding Estimator (recommended for accuracy).
Check the box if there are only two jobs total (you and your spouse or two jobs for yourself) and both incomes are roughly equal.
Fill out the worksheet on Page 3 to calculate adjustments.
Step 3: Claim Dependents
If your total income is $200,000 or less ($400,000 for married filing jointly), claim dependents to reduce your withholding:
Multiply the number of qualifying children under 17 by $2,000.
Multiply the number of other dependents by $500.
Add these amounts and write the total.
Step 4: Adjustments (Optional)
Use this step if you:
Want extra withholding from each paycheck (e.g., to cover other income like side gigs or investments).
Want to reduce withholding due to tax credits or deductions (like mortgage interest).
Use the IRS withholding estimator or consult with a tax advisor for precision.
Step 5: Sign and Date the Form
Sign and date the form to complete it.
Submit it to your employer. Do not send the W-4 to the IRS.
Tips for Single Filers
Complete Step 2 if you have more than one job or significant non-wage income.
Use the IRS withholding estimator if you want to avoid over- or underpaying taxes.
Skip Step 3 if you have no dependents.
Tips for Married Filing Jointly
If both spouses work, fill out Step 2 on the higher-paying job's W-4.
Claim dependents in Step 3 only on one spouse’s W-4.
Communicate with your spouse to avoid claiming the same deductions or dependents on both forms.
