Payroll software converts pay and time data into paychecks, tax deposits, and filed returns. On each run it builds gross pay, subtracts pre-tax items such as Section 125 benefit premiums that sit outside federal income tax, Social Security, Medicare, and federal unemployment wages [7], then figures income tax withholding by annualizing the period's taxable wages and applying the Publication 15-T percentage method to the employee's Form W-4 entries [2]. It adds Social Security at 6.2% up to the 2026 wage base of $184,500, Medicare at 1.45% with no ceiling, and an extra 0.9% above $200,000 that the employer does not match [1][3]. Full-service products then debit the company account, send direct deposits over ACH, remit each tax on the employer's monthly or semiweekly deposit schedule [13][4], and file Form 941 quarterly, Form 940 annually, and Forms W-2 and 1099-NEC by January 31 [1][5][10]. This is general information about payroll mechanics, not tax or legal advice.
\n","summary":"Payroll software is the calculation and compliance layer between your time data and your employees' bank accounts. It builds gross pay, applies deductions in a fixed order, withholds federal, state, and local taxes, moves money by ACH, deposits taxes on a monthly or semiweekly schedule, and files Forms 941, 940, W-2, and 1099-NEC. This answer walks the full pipeline and marks where your own data, not the software, decides whether the result is right.

Federal income tax withholding depends on which version of Form W-4 the employee filed and what they entered in each step of it [2]. Social Security stops once an employee's wages reach the annual base while Medicare keeps running, an additional Medicare rate switches on partway through the year for high earners [3], and federal unemployment tax runs on a separate and much smaller wage base [5]. Payroll software carries those running totals per employee and re-evaluates every threshold on every run, which is the part hand-built spreadsheets get wrong in the fourth quarter.\n\n### What it is not\n\nPayroll software is not an accounting system, although it feeds one: most products emit a journal entry with account types, debits, and credits that posts to the general ledger after each check date [14]. It is not protection from liability either, because an employer using a payroll service provider stays responsible for the deposits and the returns [9].","introHtml":"Payroll software is an application that calculates what each worker earned in a pay period, withholds the taxes and deductions that apply, moves the remaining money to the worker, and sends the withheld amounts to the agencies owed them.
