Pay-As-You-Go Workers' Comp: How It Works and When to Raise It With Small-Business Clients

Small-business owners ask about pay-as-you-go workers' comp for two reasons: they do not want to put a large deposit down at the start of the policy, and they are tired of being surprised by an audit bill. Pay-as-you-go can help with both, but it is not a different kind of coverage, and it does not make the audit go away. Agents who explain it accurately set the right expectations and avoid a frustrated call at the end of the term.

This guide covers how pay-as-you-go billing differs from traditional estimated premium, how payroll integration works, what it does and does not change about deposits and audits, which clients it suits, and what to ask the carrier and the payroll provider before you recommend it. For background, ABTC's primer on what workers' comp insurance is covers the coverage basics.

How Pay-As-You-Go Billing Differs From Estimated Annual Premium

Workers' comp premium is generally based on payroll by classification. Under a traditional billing arrangement, the carrier estimates the policy's premium at the start of the term from the employer's estimated payroll for each class code. The employer pays a deposit and then installments on that estimate. After the term ends, a premium audit compares actual payroll to the estimate, and the carrier bills additional premium or refunds the difference.

Under pay-as-you-go, sometimes called PAYGO or payroll-based billing, premium is calculated from actual payroll as it is paid. Each pay period, the payroll data goes to the carrier, which applies the rates for the relevant class codes and collects the premium for that period, typically by direct debit.

What stays the same:

• The policy. It is still a standard workers' comp policy from a carrier authorized in the state. Pay-as-you-go is a billing method. The Hartford, for example, says plainly that it "isn't a type of insurance policy," just a different way of paying for the same coverage.
• The rating. Class codes, rates, experience modification where it applies, and other rating elements work the same way.
• The employer's obligations. Collecting certificates of insurance from subcontractors, reporting injuries and cooperating with the audit are unchanged.

What changes is timing: premium tracks actual payroll month by month instead of being estimated up front and trued up a year later.

Payroll Integration and Reporting Each Pay Period

Pay-as-you-go depends on payroll data flowing to the carrier, so it works through a payroll provider or tax administrator that has an arrangement with the carrier. Each pay period, the provider reports payroll, usually broken out by employee or by class code, and the premium is calculated and collected.

The details vary by carrier and payroll provider:

• Which payroll providers are supported. Not every payroll company works with every carrier, and some carriers support only a few. If the client uses a payroll service that is not integrated, pay-as-you-go may not be available without switching.
• How employees are mapped to class codes. Someone has to set up which class code applies to each employee in the payroll system. If an employee is mapped to the wrong code, every pay period reports the wrong code.
• What payroll is reported. Payroll definitions for workers' comp are set by the rating rules, and they do not always match gross wages in the payroll system. Ask how the integration handles items such as overtime, bonuses, and owner or officer payroll.
• How payment is collected. Usually by debit from the employer's account, each pay period or on a set schedule.
• Who sees the premium. Because premium is folded into payroll, the client may stop seeing the workers' comp cost as a separate bill. The Hartford notes that the employer may lose some direct visibility into the true cost of its coverage, which is worth flagging.

Effect on Deposits and Year-End Audits

Deposits

Pay-as-you-go programs generally require a smaller deposit than traditional billing, which is often the main reason a client wants it. But it is usually not zero down. Many programs still take some initial payment. Ask the carrier what the deposit is for this client and whether it is held or applied.

The year-end audit still happens

This is the most common misunderstanding. Pay-as-you-go does not eliminate the premium audit. The Hartford answers the question directly: having pay-as-you-go "doesn't prevent your business from having an audit," and the audit still verifies payroll, checks whether class codes are accurate, and confirms subcontractors had coverage during the audit period. The Hartford also notes that most carriers require a premium audit for workers' comp policies. Audits can be done by phone, mail or in person.

What pay-as-you-go usually changes is the size of the adjustment. Because premium was collected on actual payroll all year, the gap between premium paid and premium earned tends to be smaller than under estimated billing. But "smaller" depends on the data being right. The audit can still produce additional premium when:

• Employees were mapped to the wrong class code in the payroll system
• Payments to uninsured subcontractors were not reported as payroll
• Some workers were paid outside the integrated payroll system, such as through a separate account or as 1099 contractors who the auditor treats as employees
• Payroll components were reported incorrectly for workers' comp purposes
• The business's operations changed and no one updated the classification

Which Small-Business Clients It Suits and Which It Does Not

Good fits

• Seasonal businesses whose payroll swings through the year, such as landscapers, pool services and seasonal retail. Premium follows payroll instead of a flat installment schedule.
• Growing businesses that expect to add staff during the term. Traditional estimates tend to lag growth, which shows up as additional premium at audit.
• Cash-sensitive startups for whom a large deposit is a real burden.
• Clients already using an integrated payroll provider, where setup is simple.
• Clients who were surprised by a large audit bill and want premium closer to actual payroll throughout the year.

Weaker fits

• Clients who run payroll in-house without an integrated provider, or who will not switch providers.
• Clients with complex classification, such as contractors with payroll split across several class codes based on time records. Pay-as-you-go can work, but only if the payroll system tracks the split correctly every period. Otherwise, it automates the error.
• Clients who pay many workers outside payroll, such as heavy users of subcontractors or 1099 workers.
• Clients who want to budget a fixed monthly amount and prefer predictable installments over variable debits.

State-fund and monopolistic states

In North Dakota, Ohio, Washington and Wyoming, workers' comp is provided through the state fund rather than private carriers, so a private carrier's pay-as-you-go program does not apply there. Clients in those states should check the state fund's own reporting and payment options. In other states, availability depends on the carrier, the payroll provider and the class of business. ABTC's guide to workers' comp policy design covers other structural choices to weigh alongside billing.

Questions to Ask the Carrier and Payroll Provider

For the carrier

1. Is pay-as-you-go available for this state, class of business and premium size?
2. Which payroll providers are integrated?
3. What deposit is required, and is it held to the end of the term or applied to premium?
4. How often is premium calculated and collected?
5. How is the audit conducted under pay-as-you-go, and what records will the auditor want?
6. What happens if a payroll report is late or missing?
7. Can the client switch back to traditional billing at renewal?

For the payroll provider

8. Is there a fee for the workers' comp integration?
9. Who sets up the class code mapping for each employee, and how is it changed?
10. How are workers' comp payroll definitions handled, such as overtime, bonuses and officer payroll?
11. Can the client see a report of premium by pay period and by class code?
12. What happens when an employee's job changes and their class code should change too?

Write down the answers. They are the basis for the expectations you set with the client.

Keeping Class Codes and Payroll Accurate Under Pay-As-You-Go

The most valuable thing an agent can do for a pay-as-you-go client is make sure the class code setup is right at the start and stays right. Review it at setup with the client and the payroll provider. Check the code-to-employee mapping against the policy's classification schedule. Explain to the client that if an employee moves from office to field work, or the business adds a new operation, the mapping needs to change, and the carrier needs to know.

Then, at least once during the term and again at renewal, ask for a premium-by-class-code report from the payroll provider and compare it to the policy. Gaps are easier to fix mid-term than after the audit.

Agents and account managers who want a firmer grounding in how workers' comp premium is determined, along with the employer's side of claims and injury management, can find it in the Workers' Compensation Training & Certification program. It is online and self-paced, includes one year of access, and has an optional exam for the Certified Workers' Compensation Administrator designation. It is professional training, not state insurance CE. ABTC's workers' compensation training offers insurance-side courses as well.

Frequently Asked Questions

What is pay-as-you-go workers' comp?

Pay-as-you-go workers' comp is a billing method in which premium is calculated from actual payroll each pay period, usually through an integrated payroll provider, instead of being estimated at the start of the term. It is not a different type of coverage. The policy, class codes and rating work the same way, and the employer's obligations, including the premium audit, remain.

Does pay-as-you-go workers' comp eliminate the audit?

No. Carriers generally still audit pay-as-you-go policies. The audit verifies payroll, checks that class codes are accurate and confirms subcontractors had coverage. Because premium was collected on actual payroll during the term, the adjustment is often smaller than with estimated billing, but errors in class code mapping, unreported subcontractor payments or payroll outside the system can still produce additional premium.

Is pay-as-you-go workers' comp cheaper?

Not by itself. Pay-as-you-go changes when and how premium is paid, not the rates. The total premium for a term depends on actual payroll, class codes and rating factors, the same as under traditional billing. The main differences are a smaller deposit and payments that track actual payroll. Also ask whether the payroll provider charges anything for the integration.

Does pay-as-you-go require a down payment?

Usually some, but less than traditional billing. Many pay-as-you-go programs require a smaller initial payment instead of a deposit based on estimated annual premium. The amount and whether it is held or applied to premium vary by carrier, so confirm the details for the specific client before quoting or setting expectations.

Can any payroll provider be used for pay-as-you-go?

No. Pay-as-you-go depends on the payroll provider having an integration or reporting arrangement with the carrier, and carriers support different providers. If the client's current payroll service is not supported, pay-as-you-go may not be available without changing providers. Ask both the carrier and the payroll provider before recommending it.

Which clients benefit most from pay-as-you-go?

Seasonal businesses with payroll that swings through the year, growing businesses adding staff during the term, cash-sensitive startups and clients already using an integrated payroll provider tend to benefit most. It is a weaker fit for clients that run payroll without an integrated provider, pay many workers outside payroll or have complex payroll splits that the payroll system does not track reliably.
