W-4 Step 4: $52,000 → $195.85 biweekly
Most employees fill Steps 1 and 2 of Form W-4 and stop. Step 4 is where you fix a paycheck that is either short or over-withheld: it tells your employer to tax income you earn elsewhere, to honor big itemized deductions, or to withhold a flat extra amount every period.
Default example: single, Steps 1/2 wage $52,000, biweekly (26), no Step 2 checkbox → Pub 15-T tentative $5,092/yr → $195.85 per period.
Step 4 flow (Worksheet 1A)
annual wage = (Steps 1/2 wage) + 4(a) other income − 4(b) deduction benefit
4(b) benefit = max(0, deductions − 2026 standard deduction)
tentative annual = percentage-method table for your status
per period = tentative ÷ periods + 4(c) extra
The three levers
| Step | What you enter | Effect |
|---|---|---|
| 4(a) other income | Interest, dividends, freelance, side gigs | Raises withholding — that income otherwise arrives untaxed |
| 4(b) deductions | Itemized/other deductions (full amount) | Lowers withholding — only the part above $16,100 / $32,200 / $24,150 (single / MFJ / HoH) |
| 4(c) extra per period | Flat dollar amount | Adds that amount to every paycheck (most direct anti-balance-due lever) |
The standard-deduction netting is done for you: the paper W-4 asks for a pre-netted number, which is the single most common Step 4(b) mistake. Here you enter the full figure.
Default + Step 4 scenarios (single, biweekly)
| Scenario | Annual wage after Step 4 | Tentative / yr | Per period |
|---|---|---|---|
| Default $52,000 only | $52,000 | $5,092 | $195.85 |
| $40,000 base only | $40,000 | $3,652 | $140.46 |
| $40,000 + 4(a) $5,000 | $45,000 | $4,252 | $163.54 |
| $40k + $5k − 4(b) $20k itemized | $41,100 (benefit $3,900) | $3,784 | $145.54 |
| $52,000 + 4(c) $25 extra | $52,000 | $5,092 + $650 | $220.85 |
2026 standard deduction (Rev. Proc. 2025-32 §2.14)
| Filing status | Standard deduction 2026 | 4(b) only helps above |
|---|---|---|
| Single / MFS | $16,100 | $16,100 |
| Married filing jointly | $32,200 | $32,200 |
| Head of household | $24,150 | $24,150 |
Itemized $10,000 on a single return → benefit $0 (below $16,100). Itemized $20,000 → benefit $3,900.
The dependents credit (Step 3) applies after the tentative amount with its own phase-out bands tied to adjusted gross income, so it is out of scope for this first-look tool. For the full calculation use the IRS Tax Withholding Estimator. Educational estimate from IRS Pub 15-T (Rev. Dec. 2025) and Rev. Proc. 2025-32 §2.14; not tax advice.

$195.85 per period ($5,092.10/yr): Pub 15-T percentage method on a single filer with no Step 2 checkbox, no 4(a)/4(b)/4(c). That is the form default.
The optional adjustments that fine-tune withholding: 4(a) other annual income with no withholding of its own, 4(b) itemized deductions that only help above the standard deduction, and 4(c) a flat extra dollar amount withheld every period.
The paper W-4 asks for the net value, but in this calculator enter the full amount: it nets against the 2026 standard deduction for your filing status automatically (Rev. Proc. 2025-32: $16,100 single, $32,200 married joint, $24,150 head of household).
It raises the annual wage to $45,000 → tentative $4,252/yr → $163.54 biweekly (vs $140.46 base-only). That is +$23.08 per paycheck.
It adds $25 to every period: $220.85 biweekly ($5,742.10/yr) instead of $195.85.
The dependents credit applies after the tentative amount with its own phase-out bands tied to adjusted gross income, which is out of scope for this first-look estimate. Use the IRS Tax Withholding Estimator for the full calculation.
