Editor: Diksha Yadav on Apr 30,2025

If you're operating a small business in 2025, you already know you must manage many different things— marketing, customer service, records, and employee management. Unfortunately, running a payroll for small businesses is one of the most overwhelming tasks. But, with the right software and knowledge of how to do it, payroll processing can potentially be a simple, repeatable check-off item on your to-do list.

This guide will explain how to run payroll for small businesses, from choosing the best payroll to complying with tax laws to using online payroll services that will help you streamline the process.

Why Payroll Matters More Than Ever in 2025

In the changing digital economy, payroll extends beyond issuing checks—it is compliance, employee satisfaction, financial accuracy, business reputation, etc. Payroll delays and errors may lead to unhappy employees, IRS fines, or lawsuits.

By learning what payroll services modern times have to offer for small businesses, you will save yourself time and money, in addition to honoring trusted relationships and compliance. 

Step 1: Gather Business and Employee Information

Before you can start processing payroll, it's essential to have the following in place:

• Employer Identification Number (EIN): This is important, as you'll need it when filing federal taxes.
• State and Local Tax Identification Numbers: You may have to have state registration, depending on where you're located.
• Employee Documentation: The W-4 (wage withholding) forms have been completed, the I-9 (employment eligibility verification) is in place, and direct deposit information is in place.
• Pay Schedule: Decide how often you will pay employees (e.g., weekly, biweekly, or monthly).

If you are a new small business owner hesitating over how to run payroll for a small business, taking care of this documentation ahead of time will help prevent significant problems later.

Step 2: Classify Workers Correctly

Are your workers employees or independent contractors? Misclassification is one of the most common payroll mistakes, and fines can happen. 

• Employees: These individuals should be included when paying payroll or withholding taxes.
• Contractors (1099 workers): These workers are being paid separately with no taxes withheld.

Proper classification ensures accurate tax reporting and can help you select the best payroll software for small businesses.

Step 3: Choose the Right Payroll System

Now comes the critical choice: how will you run payroll?

Option 1: Manual Payroll

• Low-cost, but very time-consuming and error-prone.
• Requires calculating taxes and submitting filings yourself.
• Best only if you have one or two employees and strong accounting skills.

Option 2: Accountant or Bookkeeper

• A professional can handle everything for you.
• Costs more, but gives peace of mind.

Option 3: Payroll Software for Small Business

• Automates calculations, tax filings, direct deposits, and benefits management.
• Common providers include Gusto, QuickBooks Payroll, ADP, Patriot, and Paychex.
• The best payroll for small businesses often combines ease of use, affordability, and scalability.

Option 4: Online Payroll Services

• Cloud-based platforms with full-service automation.
• Employees can self-service pay stubs and W-2s.
• Ideal for remote teams and hybrid workplaces.

Step 4: Understand Payroll Taxes and Deductions

Payroll isn’t just about gross wages. You’ll need to deduct and remit several taxes:

• Federal income tax
• Social Security and Medicare (FICA)
• Federal unemployment tax (FUTA)
• State and local taxes (if applicable)

Employers also contribute a portion to Social Security, Medicare, and FUTA.

If you’re using payroll software for a small business, these are calculated and filed for you automatically.

Step 5: Process Payroll

Once your system is in place and you have all the required data, follow these steps:

1. Calculate gross pay based on hours worked or salary.
2. Deduct taxes: federal, state, and local.
3. Include withholdings: benefits like insurance, 401(k), or garnishments.
4. Review and Approve: Double-check everything.
5. Pay employees via direct deposit, printed checks, or pay cards.
6. Document Everything: Keep payroll records for at least 3-4 years.

Modern payroll processing software allows batch payments and automates much of this.

Step 6: Pay Payroll Taxes and File Reports

In 2025, digital tax filing is faster and more secure than ever.

Here’s what you need to file:

• Quarterly filings: IRS Form 941 for federal taxes.
• Annual filings: Form 940 for FUTA, W-2s to employees, and W-3 to the IRS.
• State filings: As per your state’s requirements.

If you’re unsure how to run payroll for small business filings correctly, consider full-service online payroll services to automate submissions.

Step 7: Provide Year-End Tax Documents

At the end of each calendar year, you must:

• Send W-2 forms to employees by January 31.
• File the W-3 form with the Social Security Administration.
• Provide 1099-NEC forms to contractors.
• Submit ACA forms (if applicable to your business size).

Payroll software typically generates and submits these automatically.

Step 8: Stay Compliant with Labor Laws

Beyond just processing payments, payroll also intersects with

• Minimum wage laws
• Overtime regulations
• Paid leave tracking
• Employee classification laws

Keep up with federal and state changes in 2025. Many payroll services for small businesses now offer compliance tools, alerts, and HR support features.
