Payroll is the process of paying employees correctly and on time. It covers calculating gross pay, withholding taxes and deductions, paying net pay and filing and depositing payroll taxes with the right agencies. For employers, it also means keeping accurate pay records and meeting every federal, state and local deadline.

Paying employees correctly and on time, with taxes and deductions withheld and filed.
A payroll run starts with hours or salary, adds overtime, bonuses and commissions, then subtracts pre tax and post tax deductions such as retirement contributions and health premiums. In the US, employers withhold federal income tax and the employee share of Social Security and Medicare, pay the employer share, and report it, usually quarterly on Form 941. State income tax, unemployment tax and local taxes add more layers.
Most employers use payroll software, an HRIS with payroll built in, a PEO or an employer of record to handle the math, filings and deposits. Even with software, someone must keep employee data, pay rates and tax setup accurate, because the tool only pays what it is told.
Payroll links tightly with time and attendance, benefits administration and onboarding. A new hire's Form W-4, state forms and direct deposit details all feed the first paycheck.
Why it matters to recruiters
For recruiters and HR, payroll is where an accepted offer becomes real. A late or wrong first paycheck damages trust in week one and can trigger early turnover. Staffing agencies run payroll for every contractor, so errors there hit margin and compliance directly. Knowing how payroll works helps you set start dates and collect paperwork early.
An example from a recruiting desk
A 40 person company hires five people in a new state. HR registers for that state's withholding and unemployment accounts before the start date, adds the new hires' tax forms in the payroll system and checks the first preview run. Every new hire is paid correctly on the first payday, with state tax withheld from day one.
Tips that help
Register in a new state before the first employee there starts work.
Collect tax forms and bank details during onboarding, not on payday.
Review a payroll preview each cycle for unusual hours or pay changes.
Keep pay rates in one system of record so payroll and the ATS offer match.
Mistakes to avoid
Treating employees as contractors to avoid payroll taxes, which can lead to penalties.
Missing a tax deposit deadline because the payroll calendar was not set up.

In the US, employers generally withhold federal income tax and the employee share of Social Security and Medicare, then pay the employer share. Most states add income tax withholding and unemployment tax, and some localities add their own taxes. Check IRS and state guidance for your situation.
What is the difference between payroll and HRIS?
Payroll pays people and handles payroll taxes. An HRIS stores employee records such as job, manager and start date. Many modern systems combine both, but some businesses still run them separately and connect them.
Can a small business outsource payroll?
Yes. Small businesses often use payroll software, an accountant, a PEO that co employs staff, or an employer of record for workers in other countries. The employer usually stays responsible for accurate information and on time funding.
