What is Tax Withholding?
The income tax an employer holds back from each paycheck and sends to the government on the employee behalf.
Tax Withholding: definition
Rather than employees paying all their income tax at year-end, withholding collects it gradually from each paycheck - a pay-as-you-earn system. The amount is based on the employee earnings and the elections on their Form W-4 (filing status, dependents, adjustments). Correct withholding aims to match the year tax liability, so the employee neither owes a large sum nor gets an oversized refund. Under-withholding can trigger penalties.
- Employers withhold federal, and often state and local, income tax each pay run
- Amounts are driven by earnings and the employee Form W-4 elections
- Withheld tax is remitted to the authorities on a schedule and reported on Form W-2
- Distinct from FICA (Social Security and Medicare), which is a separate withholding
How Fintra handles it
Fintra payroll applies each employee W-4 elections and the current tax tables to withhold the right amount, tracks the resulting liabilities, and posts them to the ledger so remittance obligations are visible. Because payroll and accounting share one model, withheld taxes appear as liabilities until paid, and year-end reporting is built from the same records.
- Withholding computed from W-4 elections and current tax tables
- Tax liabilities tracked to the ledger until remitted
- Year-end W-2 reporting built from the same payroll data
Worked example
Frequently asked questions
What determines how much tax is withheld?
The employee earnings for the period and the elections on their Form W-4 - filing status, dependents, and any additional withholding or adjustments. Payroll applies the current federal, state, and local tax tables to these to compute the amount withheld each pay run.
What is the difference between tax withholding and FICA?
Income tax withholding covers federal, state, and local income taxes based on the W-4. FICA is a separate, fixed-rate withholding for Social Security and Medicare. Both come out of the paycheck, but they fund different things and are calculated differently.
What happens if too little tax is withheld?
The employee may owe a balance at tax time and could face underpayment penalties. Employees can adjust their W-4 to withhold more. Correct withholding aims to match the annual liability, avoiding both a large bill and an excessively large refund.
Who is responsible for remitting withheld tax?
The employer. It deducts the tax from paychecks and must remit it to the tax authorities on the required schedule, then report it on each employee Form W-2. Failing to remit withheld taxes carries serious penalties, so Fintra tracks the liability until it is paid.
