What information on a W-4 should you update if you recently started a second EMS job with new income?

• A. Health insurance plan choice and beneficiary.
• B. Filing status and number of allowances; may adjust to manage withholding.
• C. Social security number and filing status.
• D. Previous employer contact and job title.

Answer: (B)

When you gain a second job, your total income and the tax you owe can change, so withholding needs to reflect that new reality. The W-4 determines how much federal tax is taken from each paycheck based on your filing status and the number of allowances you claim. Updating these on the W-4 helps ensure enough tax is withheld across both jobs, reducing the chance of a big bill at tax time or a large refund you could have kept in your paycheck. You may adjust the filing status and the number of allowances to balance withholding; more allowances typically reduce withholding, while fewer allowances increase it. If things feel uncertain, you can use the IRS withholding calculator to fine-tune the setup or opt for extra withholding. Health insurance choices and beneficiaries are about benefits, not tax withholding, and the Social Security number is a fixed identifier rather than a changing withholding detail.
