What Does ‘Total Number of Allowances You Are Claiming’ Mean?

The phrase “total number of allowances you are claiming” historically referred to a key input on the IRS Form W-4, the Employee’s Withholding Certificate. Employers used this number to determine the amount of federal income tax to deduct from an employee’s paycheck, helping individuals align their tax withholding with their estimated annual tax liability.

The Old W-4 Form and Allowances

Before 2020, the W-4 form utilized a system of “allowances” to help calculate federal income tax withholding. An allowance essentially represented an exemption from tax for a portion of an individual’s wages. The more allowances an employee claimed, the less federal income tax an employer would withhold from each paycheck. Conversely, claiming fewer allowances meant more tax was withheld.

Each allowance typically corresponded to a personal exemption or a dependent claimed on an individual’s tax return. Employees would use worksheets provided with the W-4 form to determine the appropriate number of allowances to claim. These worksheets considered factors such as filing status, whether an individual had multiple jobs, and eligibility for certain tax credits or deductions.

Individuals might claim more allowances if they had dependents, planned to itemize deductions, or expected to receive tax credits. For instance, a married couple with a child might claim three allowances (one for each spouse and one for the child) to reduce their withholding. Conversely, fewer allowances were claimed by individuals with multiple jobs or those who anticipated significant untaxed income, to ensure enough tax was withheld throughout the year.

Impact of Allowances on Your Paycheck

The number of allowances claimed directly influenced an individual’s take-home pay and their financial situation at the end of the tax year. Claiming a higher number of allowances resulted in a larger net paycheck because less federal income tax was withheld. However, this approach could lead to a smaller tax refund or even an unexpected tax bill when filing the annual tax return if insufficient tax had been paid throughout the year.

Conversely, claiming fewer allowances meant a smaller take-home paycheck, as more tax was withheld from each pay period. This often resulted in a larger tax refund at the end of the year. The goal of accurately claiming allowances was to ensure that the amount withheld closely matched the actual tax liability, avoiding large refunds or significant tax bills that could incur penalties. Adjusting the W-4 was important after significant life events such as marriage, divorce, or the birth of a child, to ensure withholding remained accurate.

Why the W-4 Form Changed

The allowance system on the W-4 form became obsolete primarily due to the Tax Cuts and Jobs Act (TCJA) of 2017. This legislation made significant changes to the tax code, including setting the personal exemption amount to $0 for tax years 2018 through 2025. Since the allowance system was tied to personal exemptions, its foundation was removed.

Without personal exemptions, the old W-4 form no longer effectively estimated the correct amount of tax to withhold from paychecks. The Internal Revenue Service (IRS) redesigned the W-4 form, effective for 2020, to simplify the process and improve the accuracy of tax withholding. This redesign aimed to reduce instances of over or under-withholding.

How the Current W-4 Form Works

The current W-4 form, introduced in 2020, achieves accurate tax withholding without using allowances. It relies on more direct inputs to calculate the amount of federal income tax to be withheld from an employee’s pay. The form is structured into five steps, with only the first and fifth steps (personal information and signature) being mandatory for all employees.

Step 3 of the current W-4 allows employees to account for dependents, which directly impacts withholding through tax credits like the Child Tax Credit (up to $2,000 per qualifying child) and the Credit for Other Dependents (up to $500 per qualifying dependent). Step 4 provides sections for other adjustments, such as reporting other income not from jobs (like interest or dividends) or accounting for deductions beyond the standard deduction. This approach allows for a more precise calculation of tax liability at the source.

The form also includes options for employees with multiple jobs or those whose spouses work. Step 2 allows for adjustments to withholding to prevent under-withholding in households with multiple income streams, which can be done by using an online estimator, a worksheet, or by checking a box for two jobs with similar pay. These direct inputs replace the indirect method of allowances, improving federal income tax withholding accuracy.
