What is Withholding Allowance (Legacy W-4)?

By Anthony Moretti · Updated June 2026

A pre-2020 W-4 concept where each claimed allowance reduced the amount of taxable wages subject to withholding. The current W-4 replaced allowances with actual dollar amounts for deductions, credits, and additional income.

Why Withholding Allowance (Legacy W-4) matters for employers

The old allowance system was based on personal exemptions that were eliminated by the 2017 TCJA. Employees who completed a pre-2020 W-4 may continue using their prior elections, but employers cannot require them to complete a new W-4 unless a change in their situation triggers voluntary revision. Employees hired after January 1, 2020 must use the new W-4 format.

The current W-4 asks employees to enter actual dollar amounts for anticipated itemized deductions, other income not subject to withholding, and the child and dependent care credit. This produces more accurate withholding but is less intuitive for employees accustomed to claiming a number of allowances. Payroll systems must support both old and new W-4 formats for existing employees.
