What Is Payroll?

What payroll is and why it matters

Payroll is one of the largest and most compliance-sensitive expenses a business faces. Each pay period, an employer must calculate gross pay, withhold the correct federal, state, and (in the US) FICA taxes, deduct benefits, pay net wages, and then remit the withheld amounts to tax authorities on strict schedules. Errors are costly — miscalculated withholdings or missed deposit deadlines trigger penalties. Payroll also creates multiple accounting entries: wage expense, several tax liabilities, and the eventual cash payments. Getting it right matters for employees, for compliance, and for accurate financials.

A worked example

An employee earns $5,000 in gross pay for a period. The employer withholds $800 federal income tax, $310 Social Security, and $73 Medicare, plus $200 for benefits — leaving net pay of $3,617. The accounting captures: debit *Wage Expense* $5,000; credit *Cash* $3,617; and credit the various *Tax and Benefit Payable* accounts $1,383. The employer later remits those withholdings, clearing the liabilities.

How firms handle it today

Firms run payroll through dedicated payroll software, then record the resulting journal entries and reconcile payroll liabilities at close, ensuring withholdings are remitted and filings are made on time.
