How to Fill Out Your W-4
When starting a new job or experiencing a significant life change, one important task you'll need to tackle is filling out the IRS Form W-4, the Employee’s Withholding Certificate. Your W-4 determines how much federal income tax your employer will withhold from your paycheck. This form impacts your year-end tax situation, influencing whether you receive a refund or owe money when you file your taxes.
Understanding how to fill out your W-4 correctly will ensure you are neither over-withholding nor under-withholding taxes, which can save you from financial surprises in the future. This guide will walk you through each step to help you complete your W-4 accurately and with confidence.
The Basics of Form W-4
The W-4 form was redesigned in 2020 to make withholding more accurate and simpler to understand. Understanding its sections before filling it out can help in completing it accurately:
-
Personal Information (Step 1): This section requires basic details such as your name, address, social security number, and filing status (single, married filing jointly, etc.).
-
Multiple Jobs or Spouse Works (Step 2): If you have more than one job or are married filing jointly and your spouse also works, the form provides several methods to ensure accurate withholding.
-
Claim Dependents (Step 3): This is where you account for qualifying children and other dependents to determine additional credits that will reduce your tax withholding.
-
Other Adjustments (Step 4): This optional section allows for additional income, itemized deductions beyond the standard deduction, and any extra withholding you want to put in place.
-
Sign and Date (Step 5): Once completed, your W-4 must be signed to verify the information and formally submit it to your employer.
Step-by-Step Guide to Completing Your W-4
Step 1: Enter Personal Information
Begin by filling out your full name, address, Social Security number, and choose your filing status. These details are fundamental for the IRS to correctly match your information with their records.
Step 2: Account for Multiple Jobs or a Working Spouse
If you have more than one job or you’re married and your spouse works, you'll need to calculate the total number of allowances accurately:
-
Option A: Use the IRS's online Tax Withholding Estimator for more precise results. This is recommended for a clearer understanding of your tax obligations, especially when income varies significantly.
-
Option B: Account for all additional jobs on a single W-4 form by using the Multiple Jobs Worksheet provided in the IRS instructions, which factors in the earnings from all jobs.
-
Option C: If you prefer simplicity and are okay with a slightly larger refund or balance due, consider checking the box here. Ensure both you and your spouse do this for accuracy.
Step 3: Claim Dependents
In this section, you specify the number of children under 17, each worth $2,000, and other dependents you want to claim for a $500 tax credit per dependent. Calculate the total eligible credits you wish to claim, based on your expected filing status and annual income.
Step 4: Other Adjustments
Optional adjustments include:
-
Other Income: Enter amounts from other income sources like dividends or retirement, which usually aren’t subject to withholding.
-
Deductions: List deductions you expect to take beyond the standard deduction. Use the Deductions Worksheet to calculate this accurately.
-
Extra Withholding: If you prefer to have additional taxes withheld from each paycheck, list the exact additional amount you’d like withheld per pay period.
Step 5: Sign and Date
This step is straightforward but essential. After reviewing your entries, sign and date the form to authorize its completion. Without your signature, the form isn’t official.
Tips and Considerations
Review and Adjust Annually: Tax laws change, personal circumstances evolve, and you might receive a raise or bonuses, all of which could impact your tax situation. Reviewing your W-4 annually ensures it remains accurate.
Use the IRS Withholding Calculator: Available on the IRS website, this tool helps estimate your federal tax withholding and helps avoid any tax surprises.
Consider Consulting a Tax Professional: If your situation is complex—or if you're unsure—consider seeking help from a tax advisor. This can be particularly beneficial for those with multiple income streams or tax credits.
Life Changes That Might Impact Your W-4:
- Marriage or Divorce: Changes in filing status can significantly alter your tax obligations.
- Birth of a Child: This can increase your dependent claims, impacting your total tax liability.
- Job Changes: Starting a new job or taking additional work requires updates to withholding.
- Change in Income: Significant changes, such as a raise, merit reviewing your withholding rates.
Frequently Asked Questions
Do I Need to Submit a New W-4 Every Year?
No, you don’t need to submit a new W-4 each year unless your tax situation changes.
What If I’m Exempt from Withholding?
If you're exempt from withholding, write "Exempt" in the space below Step 4(c) on the W-4, but understand the nuanced rules that apply and assure you meet the criteria before doing so.
Can Filing Status Impact My Withholding?
Yes, your filing status (single, married, head of household) heavily influences the calculations, affecting the withholding amounts appropriately configured.
What Happens If I Don’t Submit a W-4?
If you don’t provide a W-4, your employer must withhold taxes as if you are single with no other adjustments, potentially leading to over-withholding or under-withholding.
