Hiring your first employee as your business grows is an exciting milestone for any business. But shifting from solopreneur to employer means learning an entirely new set of rules: tax filings, compliance deadlines, and the mechanics of getting people paid accurately and on time.
The good news is that modern payroll processing software can automate many of these tasks, from calculating tax withholdings to preparing required reports, helping reduce errors along the way.
This guide walks through the mechanics of processing payroll step by step, so you can understand what’s required, follow a structured process, and pay your staff with confidence.
What is payroll processing?
Payroll processing is the series of actions an employer takes to pay workers. The payroll management process involves everything from tracking hours and calculating wages to distributing payments and filing payroll taxes. It covers the entire process of getting employees’ wages into their bank accounts on time, with the appropriate taxes withheld and benefits contributions deducted, if applicable.
Beyond cutting checks, a payroll system calculates and withholds income taxes, coordinates benefits, and files mandatory forms. Here’s what that looks like in practice:
-
Calculate and withhold income taxes. Accurately subtract federal income tax based on the employee’s W-4, plus any state and local income tax withholdings, which vary significantly by jurisdiction.
-
Deduct employee payroll taxes. Beyond income tax, subtract the employee’s portion of FICA taxes (Social Security and Medicare).
-
Coordinate benefits and retirement. Handle selective deductions, such as health insurance premiums and 401(k) or 403(b) contributions. When applicable these are taken out pre-tax when applicable, which lowers the employee’s overall taxable income.
-
Handle unemployment and insurance. Track and process federal unemployment tax (FUTA) and state unemployment insurance (SUI). A good payroll system helps track these rates.
-
Apply post-tax deductions. These include wage garnishments such as court-ordered payments or union dues, which are taken out after taxes.
-
Remit taxes to appropriate agencies. As an employer, you act as a collection agent for the government. Your payroll software will calculate your share of FICA taxes, as you must match employee contributions dollar-for-dollar, and submit the withheld income taxes along with the required employer tax contributions.
-
File mandatory tax forms. Compliance involves strict filing schedules. This includes IRS Form 941, which is filed quarterly to report income taxes, Social Security tax, and Medicare tax withheld. IRS Form 940 is filed annually for FUTA taxes, and Forms W-2 and W-3 go to employees and the Social Security Administration each year. Your business may also be required to file state-specific tax forms as well.
-
Ensure labor law compliance. Monitor overtime pay requirements under the Fair Labor Standards Act (FLSA), tracking minimum wage increases, and maintaining the recordkeeping formats required by the Department of Labor.
Typical payroll cycle
The typical payroll cycle is the recurring schedule you follow to pay your team. This frequency—often called the payroll schedule or pay period—defines the specific period of time for which employees are being compensated in each paycheck and determines the cadence of your payroll processing work.
Common payroll processing times include:
-
Weekly. Every week (52 pay periods per year), often used in industries with high overtime or fluctuating hours, such as construction, manufacturing, or trade.
-
Biweekly. Every two weeks (26 pay periods per year), commonly used for teams with both hourly and salaried staff.
-
Semimonthly. Twice a month (24 pay periods per year), often used for salaried employees.
-
Monthly. Once a month (12 pay periods per year), sometimes used for salaried roles where state law allows longer pay intervals.
You cannot simply choose a pay frequency based on personal preference. Most states have minimum pay frequency requirements that act as a legal floor. For example, New York has a strict weekly pay requirement for manual workers, which is defined as those spending 25% or more of their time on physical labor. Paying these workers biweekly or semimonthly without a specific state waiver can lead to heavy fines. Always consult your state’s Department of Labor or a legal professional when setting your schedule.
Selecting your business’s payroll frequency also affects your cash flow, your ability to plan around fluctuating revenue, and your employees’ financial planning. Some businesses run multiple payroll schedules to stay compliant with state laws that mandate different pay frequencies for specific worker types. For example, an employer may pay hourly manual workers weekly to meet New York’s frequency requirements, while paying salaried employees semimonthly as permitted by law.
Regardless of the split, the Fair Labor Standards Act requires employers to apply payroll schedules consistently and avoid practices such as pay period manipulation that could improperly affect overtime obligations.
Automated vs. manual payroll processing
When deciding how to process payroll, you generally have two choices: manual payroll processing or automating payroll with software.
-
Manual payroll. To process payroll manually means using spreadsheets and calculators to determine an employee’s gross pay, taxes, and deductions. Although this method costs less upfront, it requires more time and a strong working knowledge of payroll regulations. It also can lead to payroll errors, and payroll compliance can become difficult to maintain as tax rules and labor laws change.
-
Automated payroll. Payroll software automates calculations, tax filings, and deposits. Using payroll processing software reduces the time it takes to complete payroll and can significantly improve payroll accuracy, especially as employee counts and pay structures grow. A good payroll system can automatically update tax tables, helping keep you in compliance with federal payroll taxes and state income tax requirements.
Basic steps for payroll processing
- Get an EIN and open payroll tax accounts
- Collect and secure employee documents
- Determine your payroll schedule
- Track and verify employee time
- Calculate gross pay, deductions, and net pay
- Pay employees
- Remit taxes and file reports
- Maintain payroll records and issue year-end forms
If you’re looking to understand what it takes to process payroll, it helps to view it not as a single payday task but as an ongoing cycle of data collection, calculation, and reporting.
Businesses often accomplish many of the steps below by using standalone payroll processing software or by integrating their ecommerce platform with third-party payroll apps or accounting software. For example, Shopify merchants can easily integrate payroll processing services using third-party apps found in the Shopify App Store. The ecommerce platform also integrates with popular accounting software like QuickBooks, which has robust payroll features.
1. Get an EIN and open payroll tax accounts
Before you can start paying employees, you must register with federal and state governments as an employer. If you don’t already have one, you need a free federal employer identification number (EIN) from the IRS, which is required for all payroll tax filings and payments. Most businesses can apply for an EIN directly through the IRS, often completing the process online in a matter of minutes.
You may also need to register with your state’s labor department and revenue agency to set up accounts for state income tax withholding and unemployment insurance taxes. While registration is standard, you can skip state income tax accounts if you operate in one of the nine states with no personal income tax, including Texas, Florida, and Washington. These agencies will assign you the account numbers you’ll use when filing your payroll reports and remitting state taxes. Requirements vary by state, so check your state’s labor or revenue agency website to confirm what registrations are needed.
2. Collect and secure employee documents
You can’t start running payroll without requesting a few forms from your new hires. When onboarding employees, you’ll need to collect or complete these key documents required for payroll processing. Many payroll softwares allow employees to complete these forms electronically, via a personal login. Otherwise, you may use paper copies and enter the data manually into your payroll provider.
-
Employment eligibility verification (Form I-9). This form verifies that the employee is legally permitted to work in the US. The employee completes Section 1 on their first day, and the employer must physically examine their identification documents and complete Section 2 within three business days of the hire. Keep these forms in a separate file—away from general personnel records—to be ready for inspection by the Department of Homeland Security or the Department of Labor.
-
Form W-4. The employee completes this to declare their filing status and adjustments, which are used to calculate federal withholding. You must keep the original signed form on file for at least four years after the tax is due or paid.
-
State tax forms. In states with income tax, the employee completes a state-specific withholding certificate. Use this to manage state-level deductions and store it alongside federal tax records.
-
Direct deposit authorization. If you plan on distributing employee wages electronically (the most common method), the employee must provide signed authorization and banking details such as routing and account numbers. Store physical copies of signed authorization (and any voided checks) in a confidential payroll file for as long as the employee uses the service, plus two additional years.
-
Benefits enrollment. If you offer benefits like health insurance or a retirement plan, you need signed documents indicating the employee’s chosen coverage and contribution levels, as these affect payroll calculations. Retain these records for at least three years for IRS and Department of Labor compliance, and make sure the deductions are accurately reflected in the payroll system.
Store completed forms securely to protect employee information. If your payroll software stores the forms for you, verify it has security controls like multifactor authentication.
3. Determine your payroll schedule
One of your first decisions is how often payroll will run. When choosing a payroll schedule, consider your cash flow predictability, the mix of hourly and salaried employees, and any state requirements that govern pay frequency.
4. Track and verify employee time
Once your payroll schedule is set, you must track the work performed during each pay period. For hourly employees, this means recording employee hours—a step that directly affects compliance with wage and hour laws.
Under the federal Fair Labor Standards Act, you must accurately record hours worked to prove your employees are receiving at least minimum wage. The rate of pay is the critical anchor here; for every workweek, you must be able to show that an employee’s total earnings divided by their total hours worked equals or exceeds the legal minimum. This is particularly important for staff who earn commissions or tips, where an employer may need to provide a “top-off” payment if the fluctuating rate of pay fails to meet the minimum wage threshold for that specific period.
Whether you use time-tracking software, a digital time clock, or manual timesheets, verify this information before payroll processing work begins to prevent payroll mistakes. Verifying time records is a legal necessity, as federal and state agencies can audit your business specifically for recordkeeping compliance.
Under the Fair Labor Standards Act, the Department of Labor can inspect your time tracking logs for several prior years, depending on the type of record and applicable law. If records are missing or incomplete, employers may face back-pay penalties during audits. You must also account for state-specific rules; for example, New York mandates that these records be retained for at least six years—double the federal requirement.
5. Calculate gross pay, deductions, and net pay
Payroll calculations begin with gross pay, or the total amount an employee earns before any taxes or deductions. In practice, most businesses rely on payroll or accounting software to perform these tax calculations automatically, but understanding the underlying math helps you catch errors and verify your payroll service is working correctly.
To calculate gross pay for hourly workers, multiplying the number of hours worked by the hourly rate, including any required overtime pay. For salaried employees, divide their total annual salary by the number of pay periods in the year. Be sure to include any additional earnings such as commissions, bonuses, or tips, where applicable.
Next, subtract income tax withholdings and other payroll deductions from the gross pay to determine net pay—the final dollar amount of the employee’s paycheck.
6. Pay employees
With the final numbers calculated, most modern businesses favor direct deposit, which electronically transfers funds from your business account to the employee’s bank account via an ACH deposit. In most cases, payroll software or a payroll provider automatically submits payroll information to your bank ahead of the scheduled pay date, which requires you to finalize payroll a few days early.
Some employees may still receive physical checks or paycards (prepaid debit cards that employers load with wages), depending on business practices and employee preferences. Regardless of the payment method, most states require you to provide access to physical or electronic pay stubs. These documents must detail the wages paid, tax withholdings, and the year-to-date totals, giving employees a clear record of how much they’ve earned and how their pay was calculated.
7. Remit taxes and file reports
The work isn’t done once employees are paid. You or your payroll software must remit the income taxes you withhold along with your own required employer tax contributions.
-
Employer taxes. You must match the employee’s Social Security and Medicare tax payments dollar for dollar. Additionally, you are responsible for paying the Federal Unemployment Tax Act (FUTA) taxes and, where applicable, state unemployment taxes (SUTA), which are generally paid entirely by the employer.
-
Filing. You must file regular payroll tax reports, such as quarterly IRS Form 941 to report wages and taxes, and an annual unemployment tax return (Form 940). Failure to file or pay payroll taxes on time can result in penalties and interest that add up quickly.
8. Maintain payroll records and issue year-end forms
The final step in payroll processing is archiving your data. Federal labor laws and the IRS require you to keep payroll records for a specific period—typically at least three to four years.
These records should include the amounts of wages paid, proof of tax payments, copies of filed tax returns, and employee tax forms such as W-4s. Good recordkeeping is your primary defense if your business is ever audited or if there is a dispute regarding employee wages. You also use payroll records to prepare year-end forms such as W-2s, which must be provided to employees by required deadlines.
Most payroll processing software automatically stores this information and creates a searchable digital paper trail, reducing the need for manual recordkeeping.
