2026 Form W-4 & W-4P Overhaul: Five-Page Expansion and New OBBBA Deduction Worksheets
The 2026 Form W-4 expands to five pages with a redesigned Step 3 (child tax credit to $2,200), an expanded 15-line Step 4(b) deductions worksheet, and new OBBBA fields for qualified tips and overtime.
- 2026 W-4 expands to five pages — up from four — to accommodate new OBBBA deduction worksheets.
- Child tax credit in Step 3 increased to $2,200 per qualifying child (up from prior years).
- Step 4(b) now has a 15-line worksheet with new fields for qualified tips and qualified overtime deductions.
- Existing W-4s remain valid — employees only need to resubmit if they want to change withholding.
- Tipped employees and those with qualifying overtime should submit a revised W-4 to reduce withholding throughout 2026.
Key Changes to the 2026 Form W-4
The IRS released the 2026 Form W-4, Employee's Withholding Certificate, and Form W-4P, Withholding Certificate for Pension or Annuity Payments, on December 11, 2025. The W-4 expands from four to five pages primarily to accommodate OBBBA deduction worksheets. The W-4P received parallel updates.
| Element | 2025 | 2026 | Change |
|---|---|---|---|
| Total pages | 4 pages | 5 pages | ↑ +1 page |
| Child tax credit (Step 3) | $2,000/child | $2,200/child | ↑ +$200 |
| Step 4(b) Deductions Worksheet | Standard lines | 15-line expanded worksheet | Expanded |
| Qualified tips deduction line | Not available | New line in Step 4(b) | New 2026 |
| Qualified overtime deduction line | Not available | New line in Step 4(b) | New 2026 |
| Existing W-4 validity | Valid | Remains valid | No change |
Step 3: Child Tax Credit Updated to $2,200
The child tax credit amount in Step 3 has been increased to $2,200 per qualifying child. Employees with qualifying children who want to avoid over-withholding throughout 2026 should submit a revised W-4 with the updated Step 3 amount. Without a revised W-4, the prior year's credit amount remains in effect.
Step 4(b): Expanded 15-Line Deductions Worksheet
The Step 4(b) deductions worksheet has been expanded to 15 lines. The primary additions accommodate OBBBA deductions:
| Deduction | Who Should Use It | Effect on Withholding |
|---|---|---|
| Qualified tip income deduction | Employees in eligible tipped occupations | Reduces withholding on qualifying tip amounts each pay period |
| Qualified overtime compensation deduction | Eligible employees with qualifying overtime pay | Reduces withholding on qualifying overtime each pay period |
| Itemized deductions (mortgage, SALT, charitable) | Employees who itemize on federal return | Reduces withholding based on estimated amounts above standard deduction |
Existing W-4s Remain Valid
Employers are not required to collect new W-4s from existing employees. Existing forms remain in effect until the employee submits a revised version. New hires from January 1, 2026 must use the 2026 Form W-4.
