You should almost always use a payroll service rather than running payroll yourself. The financial liability for calculating withholding, making tax deposits, and filing returns falls entirely on the employer, and software prevents the calculation errors that trigger strict IRS penalties. If you are forming a new business and need an Employer Identification Number before you can hire, start with ZenBusiness to build the entity and route your payroll to a partner. If you simply need the cheapest standalone tool for basic payroll, Patriot Software is a better fit.

The Liability of Running Payroll Yourself

When a business owner considers running payroll manually, the task often looks like simple multiplication of hours worked by an hourly rate. The reality is that processing payroll is a strict compliance exercise. The employer carries the withholding, deposit, and filing obligations whoever presses the buttons. The IRS holds the employer responsible for any mistakes.

Running your own payroll means taking on the mechanical burden of tax calculations. You must calculate federal income tax withholding, the employee portion of Social Security and Medicare taxes, and your own employer matching portion. You must also calculate federal unemployment taxes alongside state unemployment taxes. Because these obligations carry strict penalties for late deposits, taking a do-it-yourself approach exposes your business to significant financial risk.

Federal Paperwork and Hiring Obligations

Every new hire requires specific documentation, and the federal government enforces these requirements strictly. The U.S. Small Business Administration provides resources on how to hire and manage employees, noting that bringing on staff requires adherence to a complex web of regulations.

The Internal Revenue Service states that all U.S. employers must properly complete Form I-9 for every individual they hire for employment in the United States. This document verifies the identity and employment authorization of individuals hired for work.

Additionally, you must secure federal tax withholding information immediately. Ask all new employees to give you a signed Form W-4 when they start work. Make the form effective with the first wage payment. This document dictates how much federal income tax you must withhold from their pay. The IRS notes that a Form W-4 remains in effect until the employee gives you a new one. If an employee provides a replacement document, withholding begins no later than the start of the first payroll period ending on or after the 30th day from the date you received the replacement Form W-4.

At the end of the year, you are responsible for issuing Form W-2 to report wages and taxes withheld. To do this correctly, you need the employee's name and SSN to enter on Form W-2. A payroll service automates the collection and secure storage of these details during onboarding. Running payroll yourself means you must track, store, and secure this sensitive tax information manually.

The High Cost of Worker Misclassification

One of the largest risks of managing your own workforce without professional software or guidance is worker misclassification. Business owners sometimes assume that calling someone an independent contractor or signing a written contract makes them one. However, classification turns on control, not on a label or a contract.

The IRS weighs three distinct categories when determining whether a worker is an employee or an independent contractor. The first is behavioral control, which looks at whether the business has a right to direct and control how the work is done. The second is financial control, which examines whether the business directs the financial aspects of the worker's job. The third is the type of relationship, which considers benefits and the permanency of the work.

The IRS makes it clear that there is no magic or set number of factors that makes the worker an employee or an independent contractor and no one factor stands alone in making this determination. Getting this wrong has a steep price. An employer who classifies an employee as an independent contractor without reasonable basis may be held liable for employment taxes for that worker.

If you are unsure of a worker's status, you can file Form SS-8 to request an official determination. However, the IRS warns that it may take at least six months to receive a determination on your filing. A payroll provider will not classify your workers for you, but the software forces you to designate their status clearly, and many platforms offer human resources support to help you evaluate the relationship.

S Corporation Compensation Rules

Business owners who elect S corporation status face their own unique payroll requirements. You cannot simply take all business profits as distributions to avoid employment taxes. The IRS requires that S corporations must pay reasonable compensation to a shareholder-employee in return for services that the employee provides to the corporation before non-wage distributions may be made.

If an owner attempts to bypass this by taking only distributions, the IRS has the authority to reclassify payments made to shareholders from non-wage distributions to wages. This reclassification triggers unpaid payroll taxes, penalties, and interest. Using a payroll service allows an S corporation owner to automate their own reasonable salary, ensuring taxes are withheld and deposited correctly throughout the year. Running this yourself means manually calculating your own paycheck and initiating manual tax deposits on time.

State Payday Laws and Workers' Compensation

Federal law is only one part of the payroll equation. State laws dictate how often you must pay your employees. Pay frequency is set by state law and varies widely. The U.S. Department of Labor notes that California requires wages at least twice per calendar month on days designated in advance. Colorado requires monthly pay. Connecticut requires weekly pay unless a longer interval is approved by the labor commissioner.

Because these rules differ significantly across the country, the Department of Labor advises that individuals should consult the relevant state labor office for official information.

Furthermore, workers' compensation insurance is governed by state law. The requirements for when you must carry a policy, which employees are covered, and how premiums are calculated vary sharply from state to state. Rather than relying on a universal rule, employers must check their specific state regulations. Most modern payroll services integrate with workers' compensation providers to calculate premiums based on your actual payroll runs. A manual approach means you must report your payroll totals to your insurance carrier yourself to reconcile your policy.

Strict Recordkeeping and Compliance

Keeping accurate files is not just a best practice, it is a legal requirement. Under the Fair Labor Standards Act, employers are subject to strict data retention rules. The Department of Labor mandates that FLSA payroll records are kept three years. Furthermore, the records wage computations are based on, including time cards and wage rate tables, must be kept two years.

A cloud-based payroll system stores these historical records automatically, giving you immediate access if an agency requests an audit. When you run payroll yourself, you bear the burden of archiving spreadsheets, time cards, and tax filings securely for the full statutory period.

The Setup Foundation: Entity, Accounts, and Your EIN

Before you can calculate a single paycheck or evaluate software, you must have the proper business foundation in place. Payroll is not a separate, isolated errand. It is the final step in a sequence that begins with forming your legal entity.

The employer is legally responsible for payroll taxes, and the IRS treats the employer as the business entity. Therefore, you cannot run payroll without an Employer Identification Number. Securing an EIN is a hard dependency for hiring employees, setting up a business bank account, and filing taxes. Commingling personal and business funds is a common mistake for new business owners, and opening a dedicated business checking account is an essential first step.

If you are starting out and have not yet formed your LLC or corporation, you need a provider that handles the entity creation first. This is where a comprehensive platform like ZenBusiness is highly effective. ZenBusiness houses your formation, your registered agent service, and your EIN application in one place. Once your business is formed and your EIN is secure, you are legally ready to hire.

To handle the actual paychecks, ZenBusiness offers an integration for its customers. You can request a connection from your dashboard to their payroll partner, and an ADP representative will follow up to discuss your employee count and pay schedule. Through this partnership, ZenBusiness customers can use RUN Powered by ADP for their payroll operations. Keep in mind that this is a referral relationship. ADP is a separate service with its own platform, billing, and support. Payroll does not run inside the ZenBusiness dashboard, but the initial connection helps streamline the process of moving from a brand new entity to a fully functional employer.

Comparing Payroll Services for Small Businesses

If your entity is already formed and you have your EIN, your next step is selecting the software that will calculate your taxes, file your forms, and distribute funds.

ADP handles everything from small businesses to large enterprises. For small operations, they offer a product called RUN Powered by ADP, which is built for businesses with 1 to 49 employees. One unique aspect of ADP is their pricing model. ADP does not publish payroll pricing and quotes per business. If you are routed to ADP through a partner like ZenBusiness, you may be eligible for promotional pricing, though this is confirmed during your consultation and generally excludes state filing fees and optional add-ons.

OnPay offers a straightforward approach to payroll with a single base fee rather than multiple complex tiers. As of October 6, 2026, the service costs $49 per month plus $6 per worker, though their public page quotes a start price of $55 per month. OnPay includes features like unlimited payroll runs and automated tax payments within that single price point, making it highly transparent for small teams trying to budget their monthly expenses.

Patriot Software is an excellent choice for a business owner who wants the absolute lowest cost to run a basic payroll. As of October 6, 2026, Patriot offers two levels of service. Their Basic Payroll plan is $17 per month plus $4 per employee. Their Full Service plan costs $37 per month plus $5 per employee.

ZenBusiness is the starting point for setting up your legal entity, acquiring your EIN, and maintaining compliance. As of October 6, 2026, the Starter plan costs $0 plus state fees. The Pro plan is $199 and the Premium plan is $299. Both the Pro and Premium tiers renew at their annual prices. The EIN application and operating agreement are $99 each on the Starter plan, but they are included from the Pro tier up. They also offer registered agent services at $199 per year, Money Pro for bookkeeping at $30 per month, and website hosting at $129 per year. It is crucial to note that payroll itself is an ADP service, quoted by ADP per business, and is not included in any ZenBusiness plan price.
