Running payroll is one of those tasks that sounds simple until you actually have to do it. At first glance, it seems to mean just paying your employees. However, in reality, small business payroll also includes tax withholding, record keeping, reporting, and ensuring you follow federal and state rules.
The good news is that payroll usually follows the same repeatable process each pay period, which makes it much easier once you understand how it works.
In this guide, we’ll break down small business payroll processing, explain the different systems that businesses use, and help you understand what payroll services for small businesses can do to make this task easier.
What is small business payroll?
Small business payroll is the process of paying employees and handling the tax and reporting obligations that come with those payments. This includes:
- Calculating gross pay
- Withholding federal income tax and payroll taxes
- Issuing paychecks or direct deposits
- Filing required reports with tax agencies
If you have full-time or part-time employees, or even just hiring your first employee, payroll will be part of your ongoing responsibilities as an employer, not a one-time task. Independent contractors are handled a bit differently since you generally don’t withhold income tax or payroll tax from contractor payments. However, for contractors, you will still need the right documentation, and you may have year-end reporting obligations. Either way, whether you have employees or hire contractors, when you learn how to start a small business, you will need to ensure that you maintain compliance with federal and state rules.
How do I do payroll for my small business?
Small business payroll processing usually follows a repeatable cycle. Once you have a system in place, payroll becomes a much more manageable task. Below, we’ll go over the basics to show you how to handle small business payroll.
1. Register for employer accounts
Before you can run payroll, you need an Employer Identification Number, or EIN. The IRS uses this number to identify your business for tax purposes, and you’ll generally need one if you have employees.
Depending on your state, you may also need to register for state income tax withholding and state unemployment insurance accounts before your first payroll run.
2. Classify workers correctly
One of the first payroll decisions is determining whether a worker is an employee or an independent contractor. The IRS states that this depends on the overall relationship and the degree of control the business has over the work, not just what the contract says. Employees typically complete Form W-4 so that you can withhold the correct federal income tax. Contractors usually fill out Form W-9 so that you have their taxpayer information on file for reporting purposes.
3. Track hours and wages
Next, you need a reliable way to track what each worker has earned. For hourly employees, that means accurate time tracking. For salaried employees, it means documenting pay periods and any adjustments such as bonuses, commissions, or unpaid leave. If you have nonexempt employees, overtime matters, too. Under the Fair Labor Standards Act, covered nonexempt employees must receive overtime pay for hours worked over 40 in a workweek at a pay rate of no less than time and a half.
4. Calculate payroll taxes
Once wages are tracked, the next step is to calculate the amount to withhold and the amount the business owes. This usually includes federal income tax withholding based on the employee’s Form W-4, plus Social Security and Medicare taxes. Employers also owe their own share of Social Security and Medicare taxes, and they may owe federal and state unemployment taxes as well. If your state has income tax, you may also need to withhold state income tax from employee wages.
5. Pay employees
After deductions are calculated, you issue net pay to employees. Many small businesses use direct deposit because it’s efficient and easier to manage consistently, but paper checks are still an option. You’ll also need to choose a payroll schedule, such as weekly, biweekly, semimonthly, or monthly, depending on your cash flow, state rules, and team size.
6. File payroll tax reports
Running payroll does not end when employees are paid. Employers also have to report and deposit payroll taxes on schedule. Many businesses file Form 941 quarterly to report federal income tax withheld and both the employee and employer shares of Social Security and Medicare taxes.
State reporting requirements vary, and employers may also need to file unemployment insurance reports. At year-end, employers must provide Form W-2 to employees and file it with the Social Security Administration, while certain contractor payments must be reported on Form 1099-NEC. Payroll calendars matter, missing deadlines can lead to penalties and interest.
What are the 4 types of payroll systems?
Businesses use different payroll systems depending on their size, budget, and the complexity of their payroll needs. A company with one employee and a simple payroll may manage things differently than one with dozens of hourly workers across multiple states.
1. Manual payroll
Manual payroll means calculating wages, taxes, and deductions by hand. This gives you full control, but it also creates the most room for error. It’s time-consuming, easy to get wrong, and usually not a good long-term option once payroll becomes more complex.
2. Spreadsheet-based payroll
Spreadsheet payroll is a step up from full manual processing. Templates add structure and can help with repeatable calculations, but it still depends heavily on the person managing it. You’ll need a solid understanding of payroll tax rules, overtime requirements, filing deadlines, and proper recordkeeping to do it well.
3. Payroll software
Business online payroll systems automate much of the process. They can calculate wages, withhold taxes, generate pay stubs, and in some cases, help with filings and deposits. For many small businesses, payroll software is the middle ground between doing everything manually and fully outsourcing it.
4. Outsourced payroll services
Outsourced payroll processing for small business hands much of the payroll workload to a third party. That may include wage calculations, direct deposit, tax filings, and compliance support. Many small businesses move in this direction as payroll grows more complex or the cost of mistakes begins to outweigh the cost of outside help. The right choice depends on your payroll complexity, your budget, and how comfortable you are handling compliance yourself.
Small business payroll processing: common mistakes to avoid
A few payroll mistakes keep showing up in small businesses. Worker misclassification is one of the biggest. If you treat an employee like a contractor or a contractor like an employee, you can end up with tax and compliance problems very quickly.
Be sure to also take note of the following:
- Missing tax deposit or filing deadlines is a common issue, and penalties can add up quickly when payroll taxes are late.
- Incorrect overtime calculations are another frequent problem, especially when businesses assume that salaried pay automatically exempts employees from overtime rules.
- Poor PTO tracking can create issues if your records don’t match what employees actually accrued or used.
- Mixing personal and business finances makes payroll harder to document, harder to reconcile, and riskier in an audit.
Payroll mistakes tend to compound because one bad assumption can affect multiple pay periods, tax forms, and employee records. Good documentation is one of the best ways to reduce that risk.
How much should I charge to do the payroll for a small business?
If you’re a bookkeeper or small business service provider, payroll pricing depends on how complicated the work is. A simple one-state payroll for two salaried employees is very different from a business with hourly staff, benefits deductions, and multiple pay schedules.
Factors that influence payroll pricing
The biggest pricing factors for payroll include:
- The number of employees
- How often payroll needs to be run
- Whether the business operates in multiple states
- Whether benefits and other deductions need to be managed
- How much tax filing responsibility you take on
If you’re doing more than simply processing payroll, like handling filings, deposits, year-end forms, and compliance deadlines, your fee should reflect that added responsibility.
Typical pricing models
There are three common pricing models that payroll providers use. Refer to the list below to learn more about what each model entails.
- Per employee, per month: With this model, the provider charges a set monthly fee for each employee within the client’s organization. Typical prices range between $2 and $15 per employee, and depending on complexity, you may also charge a base monthly fee between $40 and $100.
- Flat monthly fee: In this model, you’ll charge a single monthly fee that covers your cost to handle the number of employees on the client’s business payroll, plus any additional duties you may have. Most payroll providers calculate this sum using similar numbers as above, adding up the cost per employee, plus a base fee to handle filings, compliance paperwork, or other responsibilities that you’ve agreed to.
- Tiered pricing based on size: Under this model, you’ll offer package deals that bundle services and price according to the client’s business size. Typical prices range between $50 and $200 per month for businesses with simple payroll and fewer than 20 employees, and scale up to between $200 and $500 a month for businesses with more complex needs and more than 20 employees.
Keep in mind that whatever pricing model you choose, your pricing should reflect the level of compliance responsibility that you’ve taken on.
How much does small business payroll cost?
For business owners, payroll costs come from more than one place. Expect to pay the following:
- Monthly fees for software subscriptions
- Per-employee fees for software and payroll services
- Outsourced payroll service costs
- Costs for tax filing, direct deposit, year-end forms, and other administrative details, whether handled internally or outsourced
- Penalties for errors, if they happen
The option that looks cheapest at first may not always be the least expensive in practice. Low-cost setups that cause tax errors, missed deadlines, or overtime mistakes can end up costing far more than a reliable system. Payroll is one of those back-office functions where small errors can become expensive problems.
Setting up payroll properly from the start
A smoother payroll process usually starts long before the first paycheck. Forming your business properly, getting an EIN, separating business and personal finances, and keeping organized records all make payroll easier to manage.
Platforms like Tailor Brands help entrepreneurs form an LLC and obtain an EIN so they can properly register as employers and manage payroll compliance from the beginning. LLC formation does not replace payroll registration or tax filing, but a properly registered LLC gives you a stronger foundation for handling these things correctly.
Conclusion
Small business payroll isn’t just about sending money to employees. It’s an ongoing compliance process that involves wages, taxes, reporting, deadlines, and documentation. The more clearly you understand how payroll works, the easier it becomes to choose the right system for your business and avoid preventable mistakes.
Automation can reduce risk and save time, but it does not remove your responsibility as an employer. In the end, organized records, a repeatable process, a strong business foundation, and a clear understanding of your payroll obligations are what help you protect your business.
