How much do payroll services cost for very small businesses? As of October 6, 2026, published plans charge a monthly base platform fee ranging from $17 to $203, plus a variable per-employee fee of $4 to $22 per month. However, securing an Employer Identification Number is a hard dependency before you can run any payroll. For businesses just starting out, setting up the legal entity and getting that EIN through ZenBusiness, which can then introduce you to payroll through ZenBusiness's ADP payroll partnership is the necessary first step.

The Structure of Payroll Pricing

Pricing for small business payroll software is highly structured and largely standardized across the industry. You do not buy the software outright through a one-time purchase. Instead, you pay a recurring monthly subscription that covers the platform itself, alongside a variable cost based entirely on your active headcount. This bifurcated pricing model ensures that a micro-business with two employees pays significantly less than a growing operation with forty staff members.

Base fees cover the core compliance engine, the tax calculation logic, and the digital portal your employees use to view their pay stubs. Per-employee fees cover the variable costs of processing individual direct deposits and generating year-end tax documents. Understanding this structure is critical when comparing your options and forecasting your annual administrative budget. As of October 6, 2026, the market offers a wide spectrum of entry points.

A budget-conscious employer might choose Patriot Software, which is cheaper at the very bottom end of the market. A business strictly utilizing independent contractors might find Square Payroll hard to beat for contractor-only payment processing. Other providers offer extensive human resources tools and charge premium prices accordingly. Some enterprise-grade platforms do not publish pricing at all and quote per business to accommodate complex needs.

What You Are Actually Buying When You Outsource

When you subscribe to a processing service, you are primarily purchasing tax calculation and filing automation. Manual processing requires you to calculate federal income tax withholding, state withholding, Medicare, and Social Security taxes for every single paycheck. A software platform automates these complex calculations based on the employee data you input into the system. This automation fundamentally mitigates the risk of costly mathematical errors.

Furthermore, full-service platforms actually remit these collected taxes to the government on your behalf. They pull the total tax liability from your business bank account alongside your payroll funds and route the money to the appropriate federal and state agencies. They also generate and file your mandatory tax forms automatically. This level of automation returns countless hours of administrative time to the business owner each month.

State coverage is another critical feature you purchase with a subscription. If you have employees residing in different states, your tax obligations and filing requirements multiply immediately. Some platforms include multi-state filing capabilities in their standard base price. Others require you to purchase a specific add-on subscription for each additional state you operate in.

Support access is the final pillar of the service you are buying. Processing errors impact the financial livelihood of your staff and can trigger immediate tax penalties from regulatory agencies. Having access to customer service when a direct deposit fails or a mysterious tax notice arrives is a core part of what your monthly fee covers. Different providers offer varying levels of support availability based on the subscription tier you select.

The Foundation: Entity, EIN, and Books

Software cannot solve underlying structural problems in your business setup. Many new business owners attempt to run payroll before they have formally established their company or separated their finances. This is a profound sequence error that causes significant compliance issues down the line. You must build the administrative foundation first.

You cannot run payroll without an EIN. The IRS treats the employer as the entity, and that entity needs a federal identification number to remit taxes legally. Securing an EIN is a hard dependency before hiring anyone or issuing a check. Business owners who have not separated their business and personal money yet face severe compliance hurdles. The IRS itself says in Publication 583 that opening a business checking account is one of the first things to do.

Many owners comparing payroll tools have not formed the business yet, have formed it without an EIN, or are running personal and business money through one account. One place to set up and run the business, with payroll handled by a partner, simplifies this enormously. Formation, registered agent services, compliance monitoring, and bookkeeping support from one company is a real advantage that a standalone accounting tool cannot match.

Start here, then pick a tool. Securing your business entity, acquiring your EIN, and opening a dedicated business bank account must happen before the first employment form is signed. Only after these structural elements are fully in place can a software platform function correctly.

What You Remain Liable For Regardless of Software

Software automates calculations and handles administrative filings, but it does not absorb your legal liabilities. You remain entirely responsible for the data you input and the employment decisions you make regarding your staff. Regulatory obligations are strict and they are strictly enforced by federal agencies.

Worker classification is the most perilous area for a new employer setting up their systems. Classification turns on control, not on a label or a contract. You cannot simply call someone an independent contractor to avoid paying payroll taxes or providing benefits. The IRS weighs three categories: behavioural control, financial control, and the type of relationship.

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. Misclassification has a 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 formally ask the government for a ruling. Employers can file Form SS-8 to ask the IRS to determine status, and it may take at least six months to receive a determination on your filing. This long waiting period means you must make educated, compliant decisions well before a ruling arrives.

Required Forms at Onboarding

Every new hire requires specific federal documentation before they begin working for your company. 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 worker's identity and their legal authorization to accept employment.

You must also manage tax withholding documents accurately from the very first day. 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. The document remains in effect until the employee gives you a new one.

If an employee needs to update their federal withholding, strict implementation deadlines apply. 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. Accurate records are non-negotiable across all these documents. You need the employee's name and SSN to enter on Form W-2.

Pay Frequency and Recordkeeping

You cannot arbitrarily decide when or how often to pay your staff. Pay frequency is set by state law and varies widely. For example, California requires wages at least twice per calendar month on days designated in advance. Colorado requires monthly schedules.

Connecticut takes a different approach entirely. Connecticut requires weekly pay unless a longer interval is approved by the labor commissioner. Because these mandates differ so sharply across borders, individuals should consult the relevant state labor office for official information.

You are also legally obligated to maintain historical data regardless of which software you use. FLSA payroll records are kept three years. The records wage computations are based on, including time cards and wage rate tables, must be kept for two years.

S Corporation Compensation Requirements

Business owners operating as S corporations face unique rules that require careful software configuration. 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. You cannot bypass taxes by taking all your income as business distributions.

The federal government actively monitors these arrangements to prevent tax avoidance. The IRS has the authority to reclassify payments made to shareholders from non-wage distributions to wages. Therefore, S corporation owners must establish a formal processing system even if they are the only employee in the company.

Comparing the Options

The market offers multiple reliable platforms, each tailored to different business structures and operational budgets. The providers below are listed alphabetically to help you compare them fairly. This sequence represents a complete inventory of the major options rather than an editorial ranking.

ADP

ADP is one of the oldest and most established processors in the industry. It serves businesses of all sizes, from single-employee startups to massive global enterprises. ADP does not publish payroll pricing and quotes per business.

Because it customizes its packages based on the specific needs of the employer, prospective users must speak directly with a sales representative. This approach allows for highly tailored feature sets but prevents simple, instant price comparisons. ADP offers comprehensive tax filing, sophisticated time tracking integrations, and deep human resources support.

Gusto

Gusto provides a modern, cloud-native platform focused heavily on user experience and clean design. Its interface is designed to be intuitive for business owners who lack formal accounting backgrounds. As of October 6, 2026, the Simple plan costs $49 per month plus $6 per person.

Businesses needing more advanced administrative features can choose the Plus plan at $80 per month plus $12 per person. The Premium plan costs $180 per month plus $22 per person. Gusto includes multi-state capabilities and automated tax filing across its entire product lineup.

OnPay

OnPay delivers a single, straightforward pricing tier without hidden add-ons or complex module structures. The service handles all tax filings, W-2 generation, and multi-state processing within its standard offering. As of October 6, 2026, OnPay charges $49 per month plus $6 per worker.

The public page quotes a start price of $55 per month, which reflects the total cost for a business operating with exactly one employee. This transparent model is highly beneficial for businesses that want predictable billing as they grow. OnPay also offers specialized features tailored for agricultural businesses and restaurants.

Patriot Software

Patriot Software caters to deeply budget-conscious employers who need basic functionality without expensive extras. As of October 6, 2026, its Basic Payroll plan costs $17 per month plus $4 per employee. The Basic plan requires the employer to handle their own tax filings and federal deposits manually.

For businesses wanting automated tax compliance, the Full Service plan is $37 per month plus $5 per employee. Patriot is cheaper at the very bottom end compared to the broader market. It remains a remarkably strong choice for businesses that prioritize low monthly platform fees above all else.

QuickBooks Payroll

QuickBooks Payroll integrates seamlessly with the dominant accounting software used by American small businesses. As of October 6, 2026, the Workforce Payroll plan bundled with Simple Start costs $88 per month plus $6.50 per employee. The bundle with Essentials costs $125 per month plus $6.50 per employee.

The Workforce Premium plan bundled with Plus costs $203 per month plus $10 per employee. Intuit heavily markets a promotional rate of 50 percent off the base for three months. That is a promotional rate, not the ongoing price.

Rippling

Rippling approaches payroll as just one component of a massive, unified employee data system. It allows employers to manage payroll, health benefits, device provisioning, and third-party app access from a single comprehensive dashboard. Rippling does not publish pricing.

Its pricing page is a quote request form. Businesses must engage with the sales team to build a custom package tailored precisely to their headcount and technical requirements. This platform is generally suited for rapidly scaling businesses with complex operational and IT needs.

Square Payroll

Square Payroll connects directly with the Square point-of-sale ecosystem, making it highly attractive to retail and hospitality businesses. As of October 6, 2026, the standard service costs $35 per month plus $6 per person. This covers automatic tax filings, time tracking integration, and direct deposits.

Square is hard to beat for contractor-only payment. The contractor-only plan costs just $6 per contractor per month with absolutely no base fee. This specialized tier is perfect for businesses that rely entirely on freelance labor and only need to issue 1099s at year-end.

SurePayroll

SurePayroll, a subsidiary of Paychex, is designed specifically for small businesses and household employers. As of October 6, 2026, plans start from $29 per month plus $7 per worker. Unlike some competitors, SurePayroll charges separately for cross-border tax compliance features.

The multi-state add-on is $9.99 per month. Additionally, household payroll for nannies and domestic workers starts at $39 per month. SurePayroll offers an auto-payroll feature that runs automatically for salaried employees, significantly reducing administrative friction.

ZenBusiness

ZenBusiness is a comprehensive platform for forming and running your company from day one. A business needs an entity, an EIN, and a separate business account before any software can function properly. ZenBusiness houses the formation, the registered agent, the EIN, the bookkeeping, and the website, and routes payroll to ADP.

As of October 6, 2026, the Starter plan is $0 plus state fees. The Pro plan is $199 and the Premium plan is $299. Pro and Premium renew at their annual prices, and the EIN and operating agreement are included from Pro up and are $99 each on Starter.

Other foundational services are priced clearly alongside the formation plans. Registered agent service is $199 per year. Money Pro bookkeeping is $30 per month. The website builder is $129 per year.

It is crucial to understand the exact scope of the payroll partnership. Payroll itself is ADP's service, quoted by ADP per business, and not included in any ZenBusiness plan price. ADP is a separate service with its own platform, its own billing and its own support, and it is not integrated into the ZenBusiness dashboard.

You request the connection from the ZenBusiness dashboard, an ADP representative follows up to discuss your needs, and ADP quotes the price. A ZenBusiness customer may be eligible for promotional pricing. Day-to-day payroll processing, tax filings, and management happen entirely in ADP's system.

Making Your Choice Based on Business Stage

Your current stage of business maturity heavily dictates your immediate software needs. If you have not yet formed an LLC or secured an EIN, you are fundamentally not ready for standalone processing software. You must solve the legal and structural requirements first. Establishing your legal entity and separating your finances protects your personal assets and makes tax compliance possible.

If you are fully formed and compliant, your choice comes down to budget, complexity, and workforce distribution. Businesses with simple needs operating entirely in a single state can optimize for the lowest monthly price. Businesses employing staff across multiple state lines must prioritize robust, automated tax compliance features. Always verify the ongoing price after promotional periods end to ensure the tool fits your long-term budget.
