How to process payroll for employees

Payroll is one of those processes that can look straightforward – until it isn’t. Everything seems fine until a missed deadline or a miscalculated check. Suddenly, you’re correcting errors and fielding calls from employees. And maybe even facing penalties.  

This article guides you through how to do payroll correctly, step by step, so your process holds up as your workforce grows. 

Key takeaways

• Processing payroll correctly starts with clean, accurate employee data. Errors at the input stage can compound through every calculation that follows. 
• Accurate gross-to-net calculations, including taxes and benefits, can keep employees confident in their pay and the organization on the right side of compliance.  
• Strict adherence to tax deadlines and recordkeeping requirements helps avoid the risk of costly government or tax authority penalties.  
• At scale, manual payroll processes tend to create more opportunities for error than automated ones. 

Step 1: Collect the necessary information

Clean, complete data is the starting point for doing payroll properly. Missing information at this stage may lead to processing delays or compliance issues.  

Start with business details, including:

• Employer identification number (EIN)  
• State and local tax IDs  
• Filing frequencies and jurisdictional requirements  

Next, you'll need the following employee information:

• Social Security number
• Date of birth
• Compensation structure (e.g., hourly, salary, variable pay) 
• Pay rate (hourly amount or salary amount) 
• Pay cycle (weekly, semi-monthly, bi-weekly) 
• Tax forms
• Benefit elections and deductions

Neatly compiling this information is where payroll teams sometimes hit a wall. A PayrollOrg survey found that poor-quality data inputs, late or inaccurate time data, and inputs after payroll cut-off are the top causes of decreased payroll accuracy. 

A single HCM software platform helps keep employee records connected, so updates flow directly into payroll without manual re-entry. That payoff can be significant. A recent Forrester Consulting study found that moving workforce management (WFM) and pay into a single system reduced payroll-related effort by 35%, delivering $1.4 million in savings over three years through fewer corrections and less manual work.

Step 2: Determine a payroll system

Once your data is in place, it’s time to decide on a payroll system and process that best supports accuracy and compliance. The right approach depends on your workforce size and internal bandwidth to manage the process. 

Manual payroll can work for very small businesses, but the margin for error grows as headcount and compliance obligations increase. Many organizations eventually move toward payroll automation for that reason.

Using payroll software can automate much of the process, handling everything from time tracking to tax calculations. This helps reduce manual touchpoints and gives your team a single, reliable system to manage payroll from end to end. 

Some businesses choose outsourced payroll services instead, handing off payroll processing and tax filing to a third-party vendor. This makes sense when internal teams need additional bandwidth or specialized expertise to manage payroll compliance.

To choose the right payroll system for your business, start with two questions: How complex is your workforce, payroll configuration, and how much control do you want over day-to-day operations?  

Your answers will point you toward the right fit. 

Step 3: Calculate pay

Learning how to do payroll for employees involves more than handing out a check or approving a direct deposit each pay cycle. To calculate pay correctly, employers need to account for the different ways employees may earn compensation, including: 

• Hourly pay: Total hours worked, overtime, shift differentials, and weekend or holiday premiums 
• Salaried (annual) pay: Fixed base pay, adjusted for bonuses, commissions, or unpaid leave 
• Variable pay: Incentives, reimbursements, or one-time payments 
• Premium pay: Additional compensation for work performed during nights, weekends, or holidays; applied on top of the base hourly rate 
• Overtime pay: Hours worked beyond the standard threshold, calculated at the applicable overtime rate (commonly 1.5 times the regular rate) 

Some employees may earn premium or overtime pay in addition to their regular wages, and different teams within the same organization may be paid differently. Your payroll team needs accurate records to calculate gross pay, which is the amount an employee earns before taxes and other deductions. 

Payroll software can help reduce manual calculation errors by automatically connecting approved time data to your pay rules. That way, payroll teams aren’t left to reconcile the two manually. 

Step 4: Withhold taxes and payroll deductions

Next, you’ll subtract taxes and deductions from an employee’s gross pay to reach the net pay amount. Mistakes here can trigger reporting issues (since deductions are typically made for state and federal taxes or other government programs) or result in an employee receiving the wrong amount on their paycheck. To maintain accuracy, you need to:  
 

•  Calculate gross pay based on total earnings before deductions 
• Calculate and apply pre-tax deductions, such as health insurance premiums and retirement contributions 
• Calculate federal, state, and local income taxes, along with Social Security and Medicare 
• Apply post-tax deductions, such as wage garnishments, union dues, and other voluntary deductions 
• Track employer obligations, such as unemployment taxes 
• Net pay is calculated and paid  

The real challenge in getting payroll right is staying consistent when tax rules change or employee elections vary. Payroll software that stays current with legal requirements takes that burden off your team and helps reduce the risk of compliance gaps between pay cycles. 

Step 5: Disburse payroll

Before disbursing payroll, have managers verify hours and deductions with a deadline buffer. Building in review time gives you time to catch and correct errors before funds go out. 

Most organizations use direct deposit for speed. In PayrollOrg’s Getting Paid in America survey, nearly 93% of respondents said they receive their pay that way, making it the most common payment method by far. But paper checks and pay cards may still be appropriate depending on your workforce’s needs.

Once payment details are confirmed, run a final check of totals and account numbers before releasing funds. 

Step 6: File payroll taxes

Filing payroll taxes is a separate obligation from paying employees. Employers must track, deposit, and report payroll taxes according to the schedules and requirements that apply to their business: 

• Federal income tax: Withheld from employee paychecks based on W-4 elections and submitted to the IRS on a set schedule 
• Federal Insurance Contributions Act (FICA) taxes: Covers Social Security and Medicare, split between employer and employee contributions 
• Federal unemployment tax (FUTA): Paid entirely by the employer to fund unemployment benefits 
• State and local taxes: Vary by jurisdiction and may include income, unemployment, or other regional obligations 

Many organizations rely on automated systems to track deadlines and submit filings on time. These platforms help reduce administrative effort and help support compliance across regions.

Step 7: Maintain records

Teams that know how to do payroll well keep accurate records long after each pay cycle closes. The IRS requires employers to retain employment tax records for at least four years and make them available for review at any time. 

Businesses should maintain: 
 

• Pay statements and payroll registers 
• Tax filings and remittance confirmations 
• Employee tax forms and deduction details 
• Time and attendance data 

Organized records make audits easier to navigate and provide a reliable trail for resolving any discrepancies that come up later. 

Payroll processing mistakes to avoid

Payroll errors can lead to compliance risk, as well as time and money sunk into avoidable issues. Here are some of the more common payroll mistakes and how to avoid them: 

Payroll mistake	Impact	Prevention tip
Maintaining inaccurate employee data	Can lead to incorrect pay calculations and tax errors that require costly corrections	Audit employee records regularly and use a single platform that keeps HR and payroll data in sync.
Misclassifying employees	Exposes the organization to potential legal liability and financial penalties	Document worker classification decisions and review them whenever roles or contract terms change.
Not complying with tax rules	Results in late filings, interest charges, and potential IRS penalties	Use payroll software that updates automatically when federal, state, or local tax rules change.
Making errors in time tracking	Distorts gross pay and overtime calculations, affecting both accuracy and compliance	Integrate time tracking directly with payroll so approved hours flow through without manual re-entry.
Relying on manual calculations	Increases the risk of human error, particularly as workforce complexity grows	Transition to automated payroll processing to standardize calculations across all employee types.
Applying incorrect deductions or benefit applications	Affects net pay accuracy and can create discrepancies in employer contributions	Verify benefit elections and deduction rules at the start of each plan year and after any life events.
Not establishing audit trails	Limits your ability to resolve disputes and respond to audits with confidence	Establish a records retention policy that covers pay statements, tax filings, and remittance confirmations, and store them somewhere your team can access quickly.

Determining how to do payroll for your business

The right payroll process looks different for every organization. But the ultimate goal is the same: a process that can handle complexity without creating more of it.  

Single HCM platforms like Dayforce bring HR, workforce management, payroll, and benefits together in one place, so the data feeding your payroll calculations stays current and consistent across your workforce. Employers with more complex requirements may also benefit from payroll tax services that help you stay on top of filing obligations across jurisdictions while reducing administrative burden. 

Frequently asked questions

How do you do payroll step by step?

To do payroll step by step, employers typically collect employee and business information, choose a payroll system, calculate gross pay, withhold taxes and deductions, disburse payments, file payroll taxes, and maintain records. Because each step builds on the last, accuracy at the start helps reduce errors and compliance issues later on. 

What information do employers need before running payroll?

Employers need their EIN and applicable state or local tax IDs on the business side. For each employee, you’ll need their Social Security number, compensation structure, and W-4 withholding form on file, along with any benefit elections or deduction authorizations, before the first payroll run. 

How are payroll taxes and deductions calculated?

Payroll taxes are calculated based on employees’ gross earnings and W-4 elections, then applied at the rates set by each applicable jurisdiction. Pre-tax deductions like retirement contributions come out first, followed by post-tax deductions such as wage garnishments, arriving at each employee’s net pay. 

What are some common payroll mistakes to avoid?

Some of the most common mistakes include using outdated employee data and misclassifying workers, both of which carry real compliance risk if left unaddressed. Missing tax filing deadlines and relying on manual calculations are also problematic, potentially carrying financial penalties that grow the longer they go unaddressed.

What is the difference between running payroll manually and using payroll software?

Manual payroll places the full burden of calculations and compliance on your team, making it increasingly difficult to manage as headcount grows. Payroll software automates those calculations and applies current tax rules consistently, removing the administrative overhead that tends to compound as a workforce grows.
