Payroll is the process of paying your employees — calculating what each person earns, subtracting taxes and other deductions, paying them their net (take-home) wages, and sending the withheld taxes to the government. The word also refers to the total of all wages a business pays and to the list of people it pays. In practice, “doing payroll” means running this calculate-pay-withhold-and-file cycle on a regular schedule.

When I hired my first employee, “payroll” sounded like one task. It’s really a handful of connected steps, and understanding them makes the whole thing far less intimidating. Here’s the plain-English version.

What payroll includes

A complete payroll process covers more than writing a check. Each pay cycle, it involves:

  • Calculating gross pay — wages, salary, overtime, bonuses, and commissions
  • Withholding taxes — federal and state income tax, Social Security, and Medicare
  • Taking other deductions — health insurance, retirement contributions, garnishments
  • Paying net wages — by direct deposit or check, with a pay stub
  • Paying employer taxes — the company’s share of Social Security, Medicare, and unemployment tax
  • Depositing and filing — sending withheld taxes to the IRS and state and filing the forms

The first four steps produce the paycheck; the last two keep you compliant. For the hands-on version, see our guide on how to do payroll.

Gross pay vs net pay

This is the distinction that confuses people most, so it’s worth nailing down.

Gross pay is the total a worker earns before anything is taken out. Net pay is what actually lands in their bank account after withholdings and deductions. The gap between the two is the taxes and deductions you, as the employer, are responsible for handling correctly.

TermWhat it meansExample
Gross payEarnings before deductions$1,000
WithholdingsIncome tax + Social Security + Medicare−$220
Other deductionsHealth premium, 401(k)−$80
Net payTake-home amount$700

The numbers above are illustrative, but the structure is always the same: gross, minus withholdings and deductions, equals net.

Payroll taxes in brief

Payroll taxes are the part that makes payroll legally serious. There are two sides:

The employee’s share is withheld from their paycheck — federal income tax, state income tax (in most states), and FICA (6.2% Social Security plus 1.45% Medicare).

The employer’s share is the company’s own cost on top of wages — a matching 6.2% Social Security and 1.45% Medicare, plus federal unemployment tax (FUTA) and state unemployment tax (SUTA). You don’t deduct the employer share from anyone; you owe it. We break this down fully in payroll taxes explained.

Pay periods

A pay period is how often you pay people, and you pick one that fits your cash flow and your state’s rules. The common options:

  • Weekly — 52 paychecks a year; common for hourly and trade work
  • Biweekly — 26 paychecks; every two weeks, the most popular schedule
  • Semi-monthly — 24 paychecks; twice a month (e.g., the 15th and last day)
  • Monthly — 12 paychecks; simplest but hardest on employees’ budgeting

Some states set a minimum pay frequency, so check your state’s rules before choosing.

In-house vs software vs full-service

You have three broad ways to actually run payroll, and the right one depends on team size and how much you want to touch it.

In-house by hand — You calculate everything with IRS tables and a spreadsheet. Cheapest in dollars, most expensive in time and risk; realistic only for one or two employees.

Payroll software — A tool like Gusto automates the calculations, payments, and tax filings for a flat monthly fee. The sweet spot for most small businesses.

Full-service / accountant — You outsource the whole thing to a payroll service or bookkeeper. Most hands-off and most expensive. Modern software has blurred this line by automating what services used to charge for.

Making payroll easier with Gusto

Once you understand the pieces, the appeal of software is obvious: it does every step above for you. I use Gusto because it’s full-service — it calculates gross-to-net pay, pays employees by direct deposit, and automatically withholds, deposits, and files your federal, state, and local payroll taxes, including year-end W-2s and 1099s. It’s a flat $49/month plus $6 per employee on the Simple plan, with unlimited payroll runs and no per-run fees, plus a $35/month contractor-only plan that’s free for six months.

For a business just starting payroll, that’s a meaningful chunk of the first year covered.

Frequently asked questions

What does payroll mean in simple terms?

Payroll is paying your employees: figuring out what each person earns, subtracting taxes and deductions, paying them the remainder, and sending the withheld taxes to the government. It also refers to the total wages a business pays.

What is the difference between gross pay and net pay?

Gross pay is what an employee earns before any deductions. Net pay is what they actually take home after income tax, Social Security, Medicare, and other deductions are subtracted. The difference is the taxes and deductions the employer withholds.

Is payroll the same as payroll taxes?

No. Payroll is the whole process of paying employees. Payroll taxes are the specific taxes — income tax withholding, Social Security, Medicare, and unemployment tax — that you withhold from pay and owe as the employer within that process.

Do I need payroll if I have only one employee?

Yes. Even one W-2 employee means you must withhold and remit payroll taxes and file the required forms. Payroll software handles this affordably and removes the deadline risk of doing it by hand.
