Steps 2–4: not applied to withholding or the PDF while Exempt is checked.
Step 2: Multiple Jobs or Spouse Works
Basic mode works for most users. Advanced mode improves accuracy for multiple jobs and variable income: it uses Step 4(c) instead of Step 2(c). For tax year 2026, the PDF fills the Multiple Jobs Worksheet (page 3) and Deductions Worksheet (page 4) automatically from your main-form entries when those worksheets apply (you can still use the Step 4(b) worksheet UI if you prefer to enter every IRS line yourself).
Suggestion: For better accuracy with multiple jobs, consider Advanced mode (Step 4(c) only; no Step 2(c)).
If you answer Yes in Basic mode, you can check Step 2(c) on the W-4 (two jobs with similar pay) or use the Multiple Jobs Worksheet (PDF page 3).
For the most accurate result, use the official IRS Tax Withholding Estimator, then enter the extra withholding per pay period in Step 4(c).
Estimated Step 4(c) uses the same federal income tax calculation service as pay stubs: we compare tax on all wages plus Step 4(a) and optional bonuses to tax on the highest job’s wages only, then spread the difference per pay. The per-pay amount is sized for the employer you’re submitting this W-4 to (highest job vs second-highest, per your answer below). For the closest match, use the IRS Tax Withholding Estimator.
Section 1 — Job details
For each job: expected annual wages and how often that job pays you.
Section 2 — Additional income (included in estimate)
We use Step 4(a) below (other annual income such as interest, dividends, or freelance work). Fill that field if it applies.
Section 3 — Optional (bonuses / irregular pay)
We put the estimate into Step 4(c) on the PDF; any amount you type in Step 4(c) is added on top—use 0 there if the estimate alone is enough.
