Pick the right filing status, claim dependents, set extra withholding, and avoid a tax-time bill.","totalDurationSeconds":364,"difficulty":"easy","tools":[],"materials":[],"steps":[{"number":1,"title":"Get a Blank W-4","text":"Your employer almost always hands you a blank W-4 during new-hire paperwork. If you misplaced it or need to update an old one, download the current version from the IRS at irs.gov/forms-pubs/about-form-w-4. Make sure it says \"Form W-4\" across the top and that it's the current tax year.The W-4 is not the same as the W-2. The W-4 tells your employer how much to withhold from each paycheck. The W-2 is the year-end summary you get in January. Keep a pen handy and have your Social Security card and most recent tax return nearby - you'll reference both.Watch this moment in the video."},{"number":2,"title":"Step 1 - Enter Personal Information and Filing Status","text":"In Section A, write your first name and middle initial in the first box, then your last name. On the second line, write your full street address with any apartment or unit number. On the third line, write your city, state, and ZIP. In box B on the right, write your Social Security number exactly as it appears on your card.In box C, check one of three filing-status boxes. Pick single or married filing separately for the first box. Pick married filing jointly or qualifying surviving spouse for the second. Pick head of household for the third - but only if you are unmarried and pay more than half the cost of keeping up a home for a qualifying person who lived with you over half the year. There are special rules for parents you claim as dependents; if you're unsure, check the IRS instructions on page 2 of the form.Watch this moment in the video."},{"number":3,"title":"Step 2 - Multiple Jobs or Spouse Works","text":"Skip this step entirely if you have one job and your spouse (if any) doesn't work. Otherwise, you have three options. Option (a) is reserved for future use - ignore it. Option (b) is the IRS Multiple Jobs Worksheet on page 3; use it for the most accurate result and write the answer on line 4(c) later. Option (c) is the shortcut: if you and your spouse have a total of two jobs and earn roughly the same amount at each, just check box 2C on both W-4s.If you have multiple jobs, complete Steps 2 through 4(b) only on the W-4 for the highest-paying job. Leave those steps blank on the W-4s for any other job. That's how the math works out correctly. If you don't want your employer to know about your second income, leave Step 2 alone and either add extra withholding on line 4(c) yourself or send quarterly estimated payments straight to the IRS.Watch this moment in the video."},{"number":4,"title":"Step 3 - Claim Dependents","text":"This is where you tell your employer about kids and other dependents so less tax gets withheld. Multiply the number of qualifying children under age 17 by $2,000. Multiply the number of other qualifying dependents (older kids in college, a parent you support) by $500. Add the two totals together and write the sum on line 3.In the video example, Buddy is married filing jointly and has one daughter, so he writes one child times $2,000 for a $2,000 total. The Child Tax Credit phases out at higher incomes - the form prints the income thresholds right next to the line. Only one parent can claim a child on their W-4, so if you file separately or split custody, agree with the other parent before filling this in.Watch this moment in the video."},{"number":5,"title":"Step 4 - Other Adjustments (Optional)","text":"Most people leave Step 4 blank. Use line 4(a) for other taxable income you want covered by paycheck withholding - things like interest, dividends, or retirement-account distributions where no tax is withheld at the source. Use line 4(b) for itemized deductions above the standard deduction; the Deductions Worksheet on page 3 walks you through the number.Line 4(c) is the most useful line in this section. Enter an extra dollar amount you want withheld from every paycheck. Common reasons to use it: you have a side hustle or freelance income with no withholding, you under-withheld last year and owed money, or you ran the IRS Tax Withholding Estimator at irs.gov/W4App and it spit out a target number. Whatever you put on line 4(c) gets withheld on top of the normal calculation.Watch this moment in the video."},{"number":6,"title":"Step 5 - Sign, Date, and Hand It In","text":"Sign and date the form on Step 5, then give the original to HR or your payroll team. Keep a photo or copy for your records. Your new withholding takes effect on the next pay period or two, depending on your employer's payroll cycle.Revisit your W-4 anytime your life changes - new job, marriage, divorce, new baby, home purchase, or a meaningful change in income. You can submit a fresh W-4 to your employer at any time. Many people update once a year right after they file their tax return, because that's when they can see how close their withholding actually was. The goal is paychecks that withhold just enough to cover your tax bill, no more, no less.Watch this moment in the video."}],"recipe":null,"lastUpdated":"2026-05-29T23:54:48.113Z","published":"2026-05-29T14:00:30.836Z","license":"CC BY 4.0.
