How to Fill Out W-4 Step 2b: Multiple Jobs Worksheet

To fill out Step 2(b) on the W-4, complete the Multiple Jobs Worksheet on page 3 of the W-4 instructions using the wage tables on page 5, then enter the per-paycheck result on Step 4(c) of the W-4 for your highest-paying job.¹ The worksheet exists because each employer’s payroll system treats its job as your only income, applying the full standard deduction and the lowest brackets on its own. When you hold more than one job, or file jointly with a working spouse, those tax breaks get claimed more than once and neither employer withholds enough. Step 2(b) calculates the extra dollars per paycheck that close the gap.

Do the Worksheet Once, on One W-4

You fill out the Multiple Jobs Worksheet a single time for the whole household, even if you and a spouse each have a job. The result is entered on the W-4 for the highest-paying job. Every other job’s W-4 gets Step 2 left blank.¹

Before you start, you need the annual wages for each job in the household. Use gross pay, not take-home. Pull the figures from a recent pay stub and annualize, or use last year’s W-2 numbers if the pay hasn’t changed.

Two Jobs: Use Line 1

If the household has exactly two jobs, you only touch line 1 and then jump to line 3. Turn to the table on page 5 of the W-4 instructions. There are two tables, one for married filing jointly (or qualifying surviving spouse) and one for single or head of household. Use the one that matches how you’ll file.

Find the annual wage for the higher-paying job in the row headers on the left. Find the annual wage for the lower-paying job in the column headers across the top. The dollar figure at the intersection is the annual extra withholding your household needs. Write that number on line 1, then skip lines 2a through 2c and go straight to line 3.¹

Three or More Jobs: Use Lines 2a, 2b, and 2c

With three jobs in the household, you build the number in layers so each additional job is measured against the combined income sitting above it, not in isolation.¹

Line 2a: Use the same page-5 table you’d use for two jobs. Find the intersection of the highest-paying job (row) and the second-highest-paying job (column). Enter that figure on line 2a.

Line 2b: Add the annual wages of the top two jobs together. Use that combined total as your “higher paying job” row header, and use the third job’s annual wages as the “lower paying job” column header. Enter the table result on line 2b.

Line 2c: Add lines 2a and 2b. This is your annual extra withholding total. Leave line 1 blank when you use this path.

Divide by Pay Periods on Line 3, Then Enter Line 4

Line 3 asks how many pay periods the highest-paying job has per year. Weekly is 52, biweekly is 26, semimonthly is 24, monthly is 12.¹

Line 4 divides the annual amount (line 1 for two jobs, line 2c for three or more) by the number on line 3. That per-paycheck dollar amount is what you write on Step 4(c) of the W-4 for the highest-paying job. Step 4(c) is labeled “Extra withholding” and accepts a flat dollar amount per pay period.

Do not skip the division. If the table gave you $4,800 per year and you enter $4,800 on Step 4(c) without dividing, your employer will withhold an extra $4,800 from every paycheck instead of across the whole year. You would catch it on your first stub, but the fix is to run the math on line 4 the first time.

Fill Steps 3 and 4(b) Only on the Highest-Paying Job

Step 3 (dependents and credits) and Step 4(b) (deductions) also belong on the W-4 for the highest-paying job, and nowhere else. Repeating them on a second or third W-4 would claim the same tax benefits multiple times and undo the point of the worksheet. On every other job’s W-4, leave Steps 3 through 4(b) blank.¹

If you want an additional cushion beyond what the worksheet calculated, add that amount to the line 4 result before writing it on Step 4(c). Step 4(c) only accepts one number, so any voluntary extra has to be folded in.

When Step 2(b) Is Not the Right Option

Step 2 offers three approaches and you pick one. Step 2(a) sends you to the IRS Tax Withholding Estimator at irs.gov/W4App, which the IRS calls the most accurate option because it accounts for credits, itemized deductions, and non-wage income the worksheet cannot see. Step 2(c) is a checkbox that both spouses (or both jobholders) tick when the household has exactly two jobs.¹

Two situations point away from Step 2(b):

You have self-employment income. The IRS specifically directs you to the online estimator in that case, not the worksheet.¹
You have exactly two jobs that pay similar amounts. The IRS notes the Step 2(c) checkbox works best when the lower-paying job earns more than half of what the higher-paying job does. In that scenario, ticking the box on both W-4s is simpler than the worksheet and produces a close result. When the pay gap is wide, the checkbox tends to over-withhold, and the worksheet is the better fit.¹

The worksheet’s own trade-off compared with the estimator is that it uses only wages. It doesn’t know about the Child Tax Credit, itemized deductions, interest, dividends, or capital gains. If any of those meaningfully affect your tax, the estimator will land closer to your actual liability.

Redo the Worksheet When Your Income Changes

The worksheet is a snapshot. It reflects the wages you plugged in on the day you filled it out. Rerun it and submit a new W-4 whenever the household picks up or drops a job, a spouse starts or stops working, or wages shift significantly through a raise, a cut in hours, or a large bonus. A change in filing status, or the arrival of a dependent that affects Step 3, is another prompt to redo the form.

Running the online estimator once mid-year is a reasonable check even if nothing dramatic has happened. Wage drift across two or three jobs can add up to a real gap by December that a static worksheet from January would not catch.
