Managed Payroll Service Guide for SMB Leaders
A managed payroll service for a small business is an arrangement in which a provider’s specialists run your payroll and payroll tax filing while you remain the employer. The IRS says an employer that outsources these duties generally remains responsible for them. Asure Software offers this model through AsureWorks, which runs on AsureCentral, as part of Asure’s payroll and HR solutions.
What is a managed payroll service?
Managed payroll puts the recurring work with provider specialists, who run payroll processing and payroll tax filing and reporting, plus day-to-day HR administration where the service includes it. Unlike payroll software, where your own administrator does the work, a managed service puts that work with the provider’s specialists. You keep the decisions about hiring, pay, and people.
You want payroll off your desk without handing over decisions about your people, and handing off the work can feel like handing off control. The IRS rules on third-party payers, covered below, show what moves and what stays with you.
Buyers use “outsourcing,” “payroll processing,” and “managed payroll” loosely, and payroll, payroll tax, and payroll tax filing are three different things. Payroll is paying employees, payroll tax is the withholding and employer taxes on each paycheck, and payroll tax filing is the returns and deposits that report and pay them.
How is managed payroll different from payroll software and a PEO?
The models differ in who runs payroll day to day and in who the IRS treats as the employer and whose EIN the returns go out under. Payroll software means your own payroll administrator runs payroll in a platform. Managed payroll means provider specialists run payroll while you stay the employer.
A professional employer organization (PEO) enters a co-employment relationship with you. In co-employment, the PEO asserts that it is the employer, or co-employer, of your employees and pays their wages under a service agreement, as described in Treasury Regulation 31.3504-2. A certified professional employer organization (CPEO) is a PEO that holds a voluntary IRS certification.
A payroll service provider (PSP) and a reporting agent both work under your employer identification number (EIN), while a section 3504 agent files under its own EIN.
The table shows three points on which the models differ, reflecting distinctions the IRS documents in the sources linked here.
Question
Payroll software you run yourself
Managed payroll service
PEO
Who runs payroll day to day?
Your own payroll administrator runs payroll.
Provider specialists run payroll, including payroll tax filing and reporting, on your behalf.
The IRS describes PEOs as handling various payroll administration and tax reporting responsibilities for clients.
Whose EIN do the returns go out under?
Returns go out under your EIN.
Your EIN for a payroll service provider or reporting agent. A section 3504 agent files aggregate returns under its own EIN.
A CPEO files aggregate returns under its own EIN.
Is there a co-employment relationship?
No co-employment relationship.
No co-employment relationship, and the employer role stays with you.
Yes, co-employment is the PEO model, with the PEO paying wages under a service agreement.
Payroll software and managed payroll both leave you as the employer and as the party liable to the IRS for deposits and returns. A PEO involves co-employment. With a managed payroll service, specialists do the work and you remain the employer, with control of hiring, pay, and people decisions. Under the IRS control test, anyone who performs services for you is your employee if you control what will be done and how, and the substance of the relationship, not the label, governs.
Where do AsureCentral and AsureWorks fit?
AsureCentral is for teams that run payroll and HR themselves. It is built for growing employers, with a primary range of 25 to 500 employees and reach to 1,000-plus for multi-state, multi-location, or hourly-workforce complexity, and it gives your team one login and shared data.
AsureWorks is the managed service that runs on AsureCentral, with Asure specialists doing the work, and it is a PEO alternative. Its primary range is 25 to 250 employees, and it is also used by faster-growing smaller teams and by larger employers with fragmented payroll and HR. AsureWorks involves no co-employment, you remain the employer, and you keep your own benefits plans, broker, retirement programs, and partners. Asure specialists run payroll and handle day-to-day HR administration, including payroll tax filing, reporting, employee records, new hires and changes, HR documentation, compliance administration, and benefits coordination.
Who is legally responsible when a provider files your payroll taxes?
When a payroll service provider, reporting agent, or managed payroll service handles your payroll taxes, you generally remain responsible to the IRS for federal payroll compliance, including deposits and returns. The IRS says the employer is the responsible party for federal tax deposits and payments even when a third party makes them (as of March 2026). IRS Publication 15 (2026), section 16, adds that an employer that outsources payroll and tax duties generally remains responsible for them. A private contract cannot change this. The Internal Revenue Manual says employment tax liability cannot be altered by a private agreement or contract between an employer and a third party. With a managed payroll service, you are choosing who does the work and how you will verify it, not who carries the legal responsibility.
The IRS sorts third-party arrangements by whose EIN files, as of September 2026. A payroll service provider prepares returns for you to sign. A reporting agent, authorized on Form 8655, signs and generally e-files separate returns. Both use your EIN, and you remain liable. A section 3504 agent, appointed on Form 2678, files aggregate returns under the agent’s own EIN and is liable along with you, although you still file Form 940 under your own EIN (IRS third-party arrangement chart). A CPEO files aggregate returns under its own EIN.
Who is liable and whose EIN files changes by arrangement type, so ask every provider which arrangement it operates under.
The failure-to-deposit penalty has four tiers, as of October 2026. The IRS charges 2% of the unpaid deposit for one to five days late, 5% for six to 15 days, and 10% beyond 15 days. The rate is 15% when the deposit is still unpaid more than 10 days after the first IRS notice, or on the day you receive a notice demanding immediate payment. A higher tier replaces the lower one, and the IRS may remove or reduce penalties for reasonable cause. The Trust Fund Recovery Penalty is 100% of the unpaid trust fund tax, which is the income tax withheld plus the employee share of Federal Insurance Contributions Act (FICA) taxes. The IRS may assess it against a responsible person who willfully fails to collect or pay that tax. Per the IRS, that can include responsible people at the business and at a provider.
With AsureWorks, what transfers is execution, and statutory liability stays with you as the employer.
What does a managed payroll service cover?
The service agreement sets the scope, so read it. These are obligations an agreement may assign to a provider, each tied to its rule.
* Run payroll on each pay date.
* Prepare and file payroll tax returns and make deposits on your behalf, which IRS Publication 15 (2026) says a payroll service or other third party may do.
* Prepare year-end wage forms, though you remain responsible for furnishing Forms W-2 to employees and filing Forms W-2 and W-3 with the Social Security Administration, per the IRS W-2 and W-3 instructions.
* Submit new hire reports to the designated state agency, which federal law requires within 20 days of hire, and some states require sooner.
* Honor valid withholding orders such as child support, which employers are legally required to do.
* Keep payroll records. The IRS says to keep employment tax records at least four years, and the Fair Labor Standards Act (FLSA) requires payroll records for at least three years.
Form W-2 covers employees, while Form 1099-NEC covers non-employee contractors, so these are different obligations. Wage and hour duties also stay with the employer, including classifying employees as exempt or nonexempt and paying overtime under the Fair Labor Standards Act and state law, so give the provider accurate hours, pay rates, and classifications. The new hire report goes to a state agency, and the IRS does not receive it. Pay frequency (Department of Labor state payday table), state income tax withholding, and state unemployment registration are set state by state. The Department of Labor’s directory of state unemployment tax agencies is the place to start for registration.
What drives the cost of a managed payroll service?
Cost depends on the scope of work, headcount, the number of states where you have employees, and added services such as benefits administration or HR support. Ask each provider for a written fee schedule and what the base fee covers, such as off-cycle runs, year-end forms, and garnishment processing.
The useful comparison is the provider’s fee against what payroll costs you today in staff time and software. The IRS adds one neutral data point about a different model, saying PEOs are typically paid a fee based on payroll costs.
AsureCentral and AsureWorks pricing is a custom quote based on employee count, setup (self-service, hybrid, or fully managed), the plan chosen, and the modules added, for example Asure HR Compliance, Asure Time & Attendance, Asure Recruiting, or 401(k) Plans.
When does handing off payroll make sense?
Payroll runs on a fixed calendar, and the work does not pause when your payroll administrator is out. The third-quarter Form 941 is due Monday, November 2, 2026, because October 31 falls on a Saturday, or Tuesday, November 10, 2026 if all deposits were made on time (IRS Instructions for Form 941), and Forms W-2 and W-3 for 2026 are due February 1, 2027 (IRS Instructions for Forms W-2 and W-3). Handing the work to specialists can make sense when payroll is pulling leadership time from running the business, when one person holds all of the payroll knowledge, or when a hire in a new state adds registration and reporting you have not handled before. Because you generally remain responsible to the IRS when a managed payroll service does the work, the case for handing off rests on capacity and continuity, not on shifting liability.
How do you evaluate a managed payroll provider?
Evaluating a provider comes down to a short set of questions, and the IRS’s own guidance supplies most of them.
* Ask which IRS arrangement type the provider operates under and whose EIN the returns file under.
* Ask whether the provider acts as a reporting agent under Form 8655. If so, ask whether it sends the quarterly written statement that the employer remains responsible for filing and paying on time, as IRM 5.1.24 describes and an IRS Tax Tip from May 2023 corroborates.
* Keep your own Electronic Federal Tax Payment System (EFTPS) enrollment, or IRS Business Tax Account access if you are eligible, so you can verify deposits yourself. EFTPS shows 16 months of payment history.
* Keep your own business address as the IRS address of record, and do not change it to the provider’s address.
* Get the scope, the fee schedule, and the name of your accountable contact in writing, including whether W-2 preparation, filing, and delivery are covered.
* Know the escalation path. File Form 14157 if you suspect improper or fraudulent payroll service provider activity involving deposits or returns. Contact the IRS promptly about any notice a provider problem causes, per the IRS guidance on outsourcing payroll duties.
The IRS says a provider’s first missed payment should raise a red flag, and your own EFTPS or Business Tax Account view is how you would see one.
What should you do before you talk to a provider?
Three actions put you in a position to compare providers on facts. First, confirm you have your own EFTPS or IRS Business Tax Account access, so you can see deposits. Second, write down which payroll tasks you want a provider to own and which ones you keep. Third, ask each provider for its arrangement type, EIN, written scope, and fee schedule.

Frequently Asked Questions
How is a managed payroll service different from a PEO?
A PEO operates under co-employment, and a managed payroll service does not. In co-employment, the PEO asserts that it is the employer, or co-employer, and pays wages under a service agreement (Treasury Regulation 31.3504-2). With a managed payroll service such as AsureWorks, you remain the employer.
What does a managed payroll service include?
A managed payroll service includes whatever its service agreement assigns to the provider, so read the written scope. An agreement may assign running payroll, filing returns, making deposits, year-end wage forms, state new hire reports, and honoring withholding orders. You still own the duty to furnish Forms W-2 to employees and to file Forms W-2 and W-3 with the Social Security Administration.
How much does a managed payroll service cost for a small business?
Cost depends on scope, headcount, the number of states where you have employees, and added services such as benefits administration or HR support. Ask each provider for a written fee schedule, and ask Asure for a custom quote.
When should a small business consider outsourcing payroll?
A small business should consider outsourcing payroll after a hire in a new state, a tax notice or missed deposit, or payroll pulling leadership time from running the business. A hire in another state brings state unemployment registration and new hire reporting, and both vary by state. The Department of Labor directory of state unemployment tax agencies is a starting point.
What should you look for in a managed payroll provider?
Look for a provider that can state its arrangement type and EIN, send the quarterly written statement if it is a reporting agent, leave you with your own EFTPS or IRS Business Tax Account access, and put scope and fees in writing. Each item lets you check the work yourself.
What are the benefits of managed payroll for HR leaders?
A managed payroll service can take recurring payroll and payroll-administration work off an HR leader’s plate while the employer keeps decisions about people. Asure HR Compliance, an add-on to AsureCentral or AsureWorks, adds on-demand support from certified HR professionals.
