Working spouse

What's your W4 recommendation when both spouses work full time?

Update:  we file jointly; $77,500 AGI; our goal is to pay as close to $0 when we file

You should focus on Step 2 of the W4 form: Multiple jobs or spouses work. If you have one job each that pays relatively the same amount, you can check the box in Step 2(c). 

If you and your spouse have multiple jobs or one job pays more than half of the other job, fill out the worksheet for Step 2(b) for only one of the W4s. Enter the results for that Step 2(b) worksheet on Line 4(c).

For either choice in Step 2, be sure to complete Step 3 for only one W4s you complete for your employer If you have dependents.

Best recommendation for married taxpayers that both work is to update the highest earner's Form W-4 to reflect the second job and ensure proper withholdings based on the actual tax brackets for your income level. You can complete this by checking the Box on Line 2c of the Form W-4 and reviewing Line 4c including the Multiple Jobs Worksheet in the instructions to Form W-4.

For married taxpayers, coordinating the withholdings is essential, given the potential combined income to affect tax brackets and tax liabilities. The goal is to withhold enough to match your tax liability, avoiding both a large tax bill and overpaying, which effectively gives the government an interest-free loan.

Key Steps to Adjust Withholdings

To ensure you and your spouse do not owe money each year:

1. Understand Your Tax Situation
   • Combined Income and Filing Status: Most Couples benefit from filing jointly, which doubles certain deductions. However, calculate both joint and separate filing options to determine the most advantageous approach. 
   • Deductions and Credits: Account for eligible deductions (e.g. mortgage interest, charitable contributions) and credits (e.g. Child Tax Credit) that reduce taxable income. 
   • Use the IRS Tax Withholding Estimator.
2. Complete and Update Form W-4
   • Submit New Forms to include the Multiple Jobs Worksheet: If both spouses work, use the Multiple Jobs Worksheet to coordinate withholdings. This prevents under-withholding, which can lead to a tax bill. For example, if both earn similar amounts, check the box on Line 2c of Form W-4 to indicate this, ensuring proper withholding. 
   • Additional Withholding: Use Line 4c on Form W-4 to request extra withholding if you anticipate owing more due to non-wage income or other factors. This can help cover potential shortfalls. 
3. Review and Adjust Periodically
   
   • Annual Review: Check withholdings at least once a year, especially after major life events. The IRS recommends a "Paycheck Checkup" to ensure withholdings align with your tax liability.
   • Monitor Paystubs: Regularly review paystubs to confirm correct amount is being withheld.
