Workers’ Compensation: What’s payroll got to do with it?



“Payroll” used to have a simple meaning.  According to the Online Etymology Dictionary:
payroll (n.)1740, from pay (v.) + roll (n.); "total amount paid to employees over a period," hence, via records-keeping, "list of employees receiving pay." [ See https://www.etymonline.com/word/payroll ]

Today, the word “payroll” more often than not refers to the department or system that manage employer costs for a range of employee compensation components. 

For workers’ compensation, payroll can have different meanings depending on your jurisdiction and whether you are a worker or an employer.  Rules in different jurisdiction may use different terms to describe or define payroll.  Common terms include wages, salaries, benefits, fringe benefit, and remuneration or earnings—often used interchangeably—but they are all referring to the same thing:  money paid by the employer to a worker or on behalf of a worker as part of compensation for labour/work performed.  Rating bureaus, legislation or policy for each jurisdiction define which components of employer costs of employee compensation are subject to rating and included in the premium calculation.   

For employers, correctly reporting the payroll components and knowing about any caps or limits is critical to the calculation of the overall workers’ compensation premium; for workers, knowing which payroll components are covered in the calculation of temporary total disability benefits as well as limits on those benefits is essential to determining the adequacy of the coverage in the event of a work-related injury.  More on that in a future post.   For policy makers and those of us who engage in comparative analysis of workers’ compensation coverage, benefits and costs, the exact meaning of payroll in each jurisdiction is essential.

“Payroll” and the Components of Employer Costs for Employee Compensation


The US Bureau of Labor Statistics (BLS) uses  “Employer Costs for Employee Compensation” to more accurately report the main components of employee compensation.  The March 2019 release [USDL-19-1002] provides the following synopsis:

Employer costs for employee compensation for civilian workers averaged $36.77 per hour worked in March 2019, the U.S. Bureau of Labor Statistics reported today. Wages and salaries cost employers $25.22 while benefit costs were $11.55…

Note, in this context, “civilian” workers include those employed in the private nonfarm economy (except those in private households) and workers in the public sector (except the federal government).

I’ve mapped the values from the US Bureau of Labor Statistics release to illustrate the relative size of each component of employee compensation for the average hour worked by a civilian worker.  

Note:  Canadian and Australian data are not available in the same format.  A recent study of manufacturing hourly compensation demonstrated a similar pattern for the main components (social insurance, wages or salaries, and direct benefits) paid by employers in Canada and Australia:

  
The main divisions of employer costs for employee compensation under the BLS study are wages or salaries and benefits.  Many of the benefit components are “wage-like”; these include paid leave for vacation, statutory holidays, sickness and personal reasons.  Some components are related to production needs and include overtime and shift differentials.  Many employers provide insurance coverage for life, health, short-term disability, and long-term disability.  The cost of these coverages may be shared with the employees (with worker contributions deducted from the wages or salary) but are otherwise a form of earnings, providing value that a worker might otherwise have to purchase.  Retirement plans (including defined benefit [DB in the graphic] and defined contribution [DC in the graphic] plans) are essentially deferred earnings typically based on wages, salary and other wage-like compensation.

In the graphic of the employer cost of employee compensation above, the “wages and salaries component” is shown in blue. “Benefits” are grouped into the following categories:  wage-like benefits shown in green, state or federally mandated assessments shown in yellow, and workers’ compensation shown in brown. 

This last group of benefit components are mandatory or statutory payments required of employers.  Social Security, Unemployment Insurance, Medicare, and Workers’ Compensation require employers pay a percentage of “earnings” over and above any contribution required of workers (typically paid out of gross earnings and often lumped together as “payroll taxes”).   

Each jurisdiction has its own rules regarding which parts of employee compensation are to be assessed at what rate.  The workers’ compensation component of this average hourly payroll example is about $0.46 or 1.25% of total employer cost of employee compensation [$36.77]. For workers’ compensation, however, total employer cost of employee compensation does not equate to reportable or assessable payroll for workers’ compensation premium calculations.

Workers’ compensation funding:  Total Premium = Rate  x  Payroll

Workers’ compensation insurers are funded by the premiums paid by employers.  Each employer’s total premium is the sum of the premiums paid for each classification of workers covered by workers’ compensation based on a premium rate (usually expressed as a dollar cost per $100 of payroll) applied to the reportable payroll for workers in each classification.  Generally speaking, industries (or occupations) with higher rates of injury and greater severity of injury in terms of dollar costs for compensation, medical and rehabilitation expenses will attract a higher premium rate.  The underwriting process may also modify rates based on claim experience.  For the purpose of this discussion, these rating provisions are not critical.  What is critical is how “payroll” figures into the process. 

Not all components of employer costs for a worker attract a premium but most workers’ compensation system defined which components are considered “reportable” or “assessable” payroll.  How the payroll is defined can impact the rate required to result in the premium income necessary to cover expected losses (and other costs including administration and profits).   To illustrate this, consider the hypothetical average hour of work represented in the graphic above. The  $0.46 required to insure that one hour represents 1.25% of total employee compensation.   Put another way, a premium rate of $ 1.2669 per $100 applied to all the components of employee compensation would be required to generate hat same $0.46.   A larger rate would be required to generate that $0.46 if some components are omitted from the calculation.  A rate of  $1.35 per $100 applied to all wages, salary and benefits except the federal and state UI, social security and Medicare mandatory employer contributions would be required to generate that same $0.46.  The total employer cost for workers’ compensation insurance remains the same but the percentage or rate depends on the denominator used to determine that cost.

NAIC:  “Total Payroll: universally available… readily verifiable”

The National Association of Insurance Commissioners (NAIC) reviewed various alternatives to total payroll as the basis for premium calculation and concluded: 

Any system of adequate and reasonable rates requires that the same overall premium to be collected to pay the losses incurred and the expenses of conducting the business, regardless of the basis under which such premium is collected. Thus, the simplest and most readily verifiable basis is of the greatest advantage to all concerned. Total payroll offers the only universally available basis and is the most readily verifiable of any base which has been found.
The present approach, which requires the use of total payroll, has demonstrated to be a fair and practical method in computing worker's compensation insurance. A certain amount of premium must be developed to pay for claims and assure the continuance of necessary services to the insured. Since premium is the product of the rate and exposure base, any reduction in payroll through the use of a payroll cap ultimately results in an increase in the rate, otherwise the overall premium collected will not remain the same.

In its annual review of Workers’ Compensation Benefits, Costs, and Coverage, the National Academy of Social Insurance (NASI.org) uses total payroll as its denominator in determining the employer cost of workers’ compensation on a state by state and national basis.  The resulting cost per $100 payroll is not a proxy for an average workers’ compensation rate but a standardized way of looking at the workers’ compensation component of employer cost across jurisdictions and timeframes. 

While “payroll” records are available and auditable, “reportable” or “assessed” payroll may vary greatly from state to state because of limitations and exceptions to what is included or excluded from the payroll calculation.  The “full payroll” approach may also engender a false sense of security about the extent of coverage; just because you pay a premium on total payroll you might assume all components of employee compensation are “covered” against losses.  This is generally not the case.  Different definitions of payroll and restrictions on maximum temporary and permanent benefits effectively leave much of worker’s wages uninsured.  More on that in a future post. 

What’s Reportable as Payroll for Workers’ Compensation?

Most US jurisdictions define “reportable” payroll as including the following:
  • Wages and Salaries
  • Vacation and Holiday Pay
  • Bonuses and Commissions
  • Payment by employer into statutory insurance and/or pension plans [Social Security, UI, Medicare]
  • Sick pay - Paid Leave provided by the employer
  • Employee contributions to a 401k [retirement savings],  
  • Deferred compensation plan
  • The value of lodging or rental of an apartment or house provided to an employee
  • Meals provided by the employer (at no cost to the worker)
  • Stand-by, On-call, Travel or “Show Up” pay
  • Payments for hand tools provided by the employee, either directly or through a third party

Other items may be included or excluded from reportable payroll depending on the state. For example, in most states, overtime premiums (e.g., “time and a half “ or “double time” paid for overtime hours worked) are not reportable and only the straight-time portion is included in the reported payroll for workers’ compensation purposes.  Nevada and Pennsylvania do not exclude overtime pay.  Most Canadian jurisdictions include the full value of overtime (e.g.,  if overtime is paid at twice the hourly rate than the full value of the wages for the straight time  and  payment for the overtime including other amounts associated with any overtime) are included in the assessable payroll calculations.  Most states exclude tips and gratuities but New Jersey includes them for most classifications.   [see NCCI,   Basic Manual (2001 Edition) “Rule 2  Premium Basis and Payroll Allocation” for a more complete listing of payroll inclusions, exceptions and limitations commonly used in the US.  Many jurisdictions publish a version of the rule either in the NCCI wording or with minor modifications.  See, for example, The Minnesota Workers’ Compensation Insurers Association, Inc. (MWCIA.org) Basic Manual  or North Carolina Rating Bureau (NCRB.org) “Rule 2- Premium and Payroll”  ].          

Some states limit payroll subject to reporting and assessment for premium calculations.  Notably, Nevada has a $36,000 maximum or cap  [see https://www.wcf.com/about-your-policy-nevada ].  The payroll for each employee is capped at $36,000 annually for the purposes of calculating  workers’ compensation premiums; no workers’ compensation premium is collected for reported payroll above this amount. 

Several other states have maximums for specific occupations.  The Bureau of Workers’ Compensation [BWC] in Ohio also has construction class codes where payroll limitations apply.  Construction industry payroll reporting limits to weekly maximum of $1425; earnings that would otherwise be part of total reportable payroll that exceeds that limit for any individual are excluded from the calculation.  New York  similarly restricts payroll for inclusion in the workers’ compensation premium calculation for dozens of construction classification codes [see http://x.nycirb.org/library/index.cfm?man=wcelmanual&chapter=PART%20I&sub=RULE%20V#collapse195   part G]. 

Although corporate officers, directors, partners and sole proprietors make up a small percentage of workers that may be covered by workers’ compensation, their remuneration is often a significant segment of a firm’s overall payroll.  Many states allow workers’ compensation coverage for these categories of workers but often provide both minimum and maximum dollar values or flat amounts to be included in total payroll for workers’ compensation premium calculations.  In Massachusetts, for example, corporate officers are assessed at a minimum of $11,400 and a maximum of $57,200 while partners are assessed at a flat rate of $50,400 [as at Oct 2018].  Maryland has a corporate officer minimum at $57,200 and a maximum value set at $228,200 with partners as a flat rate of $56,900 [as at Jan 2019]. 

Variations and Alternatives

Not all states use payroll as the basis for calculation of premium.  Most notably, Washington state uses “hours of exposure” – a risk-based metric—as the main basis for the premium calculation.  This works well in a state where workers pay between 20 and 25% of the cost of workers’ compensation through worker-paid premiums.  On the other hand, the premium rates charged workers and employers are not easily compared across jurisdictions and  “worker hours” are far less transparent and auditable than actual dollars paid. 

Washington state uses another alternative to payroll and worker hours for the purposes of its rate calculations in at least one construction-related risk.  Wallboard or drywall installation is assessed “by square footage”.  This is an auditable, objective alternative as a basis for rate calculation. 
Outside the US, the general term “payroll” is often expanded to “assessable payroll”.  This term recognizes that there are limitations and caps.  Assessable payroll will be less than total payroll; as a consequence, jurisdictions with payroll limitations or caps will likely have higher workers’ compensation premium rates than jurisdictions without payroll limitations or caps.  This is particularly important when comparing or ranking workers’ compensation premium rates.

Canadian workers’ compensation boards typically use “assessable payroll” terminology and include both wages and employer-paid benefits (sick leave, bonuses, profit sharing, employer contributions to pensions, accommodations, gratuities, etc.) but notably exclude employer contributions to Canada’s social insurance plans (Canada Pension Plan, Quebec Pension Plan, Employment Insurance).   Each jurisdiction publishes its own rules on what constitutes assessable payroll [See, for example, WorkSafeBC’s Assessment Manual, WSIB’s Operational Policy Manual].   Most align their definitions of earnings to be in line with taxation definitions of earnings reported Canada Revenue Agency (CRA) requirements for reporting earnings [ See Form T4 – Statement of Remuneration issued annually to workers and filed electronically with governments reporting earnings and certain other income and deductions made from earnings].

The reported payroll is typically limited by a per employee maximum assessable earnings amount.  This is typically the maximum insurable earnings. The Association of Workers’ Compensation Boards of Canada (AWCBC.org) provides the following:

        Maximum Assessable / Insurable Earnings
Province/Territory                                               2019
Manitoba                                                            $127,000
Alberta                                                                 $98,700
Ontario                                                                 $92,600
Northwest Territories and Nunavut                     $92,400
Yukon                                                                  $89,145
Saskatchewan                                                      $88,314
British Columbia                                                 $84,800
Québec                                                                $76,500
Newfoundland and Labrador                              $65,600
New Brunswick                                                   $64,800
Nova Scotia                                                         $60,900
Prince Edward Island                                          $55,000

Note:  Manitoba has no maximum insurable but caps assessable payroll at $127,000 except for Personal Coverage available for purchase by sole proprietors, partners or directors where the Maximum Optional Coverage is $502,200 (for 2019). 

Note:  Alberta WCB adopted “compensable earnings” as opposed to “insurable earnings” in 2018 because as of September that year, worker compensable benefits are no longer capped by the individual payroll assessment limit. 

Australian jurisdictions typically define payroll to include most of the same items US and Canadian jurisdictions include.  Queensland’s WorkCover Employers Wages Definition Manual [see https://www.worksafe.qld.gov.au/__data/assets/pdf_file/0007/3040/Wages-definition-manual.pdf] notes the following inclusions and exclusions for assessment purposes:
Inclusions
(a) Total of all PAYG [pay as you go] gross salary and wage payments
(b) All superannuation payments including super salary sacrifice
(c) Fringe benefits and other entitlements having a monetary value
(d) Total of all individual contractor payments for deemed workers
Exclusions
 (f) Any allowances or expenses reimbursed for work related expense included in (a)
(g) Lump sum termination payments included in gross wages (a)
(h) Excess period payments (i) Compensation payments reimbursed by WorkCover
(j) All payments made to, or in respect of, Directors / Trustees / Partners

Additional payroll-based assessments

Three US states have features related to the funding of their workers’ compensation systems that involve additional consideration. 

In addition to the premium charged employers in New Mexico, workers and employers are also assessed on a per capita per quarter.  Employers pay $2.30 per capita and workers employed at the end of a quarter have a $2.00 charge.  The employer portion is an employer cost of employee compensation.  The worker portion is a deduction from earnings. 

Oregon requires employers and workers contribute to the Worker Benefit Fund on an hour worked basis.  In 2019, this assessment is 2.4 cents per hour worked with employers and employees each paying 1.7 cents per hour worked. The employer cost of this payroll amount is a component of workers’ compensation cost; the worker contribution is a deduction from earnings. 

Washington state’s premium is based on hours of exposure and worker in that state pay a proportion of the premium.  This would be considered a deduction from earnings rather than an employer cost component. 

The premium charged may or may not include funding for uninsured employers, oversight, or other functions like occupational safety and health.  States apply separate assessments based either on premium totals or payroll.   California, for example, assesses premiums by applying the following factors for 2019:

Workers’ Compensation Administration Revolving Fund Assessment (WCARF)      0.014479
Uninsured Employers Benefits Trust Fund Assessment (UEBTF)                                   0.000831
Subsequent Injuries Benefits Trust Fund Assessment (SIBTF)                                        0.002737
Occupational Safety and Health Fund Assessment (OSHF)                                              0.003765
Labor Enforcement and Compliance Fund Assessment (LECF)                                      0.003431
Workers’ Compensation Fraud Account Assessment (FRAUD)                                       0.002878

For self-insured employers, a different set of factors are applied to indemnity payments. Whether the base is premium or indemnity, the underlying payroll definition with possible limitations and caps are inherently reflected in the calculation. In comparing rates between jurisdictions, it is essential to determine the impact of these factors. 

Concluding comments

How payroll is defined and the limitations, caps, and exclusions imposed on payroll can vary widely between jurisdictions.  As an employer, if your reported payroll for workers’ compensation includes income above a cap or limit, you will be paying too much in total premium and other assessments that rely directly or indirectly on premium.

For policy analysts,  It is insufficient to compare a workers’ compensation premium rate without considering the payroll base and associated caps or limits to which the premium rate is applied.  That reported or assessable base may differ significantly across any set of jurisdictions under comparison. 

Despite the arguments for the use of full payroll as the basis for premium calculation, the practice may give employers and workers a false sense of security.  Many systems limit the workers’ compensation indemnity payable, effectively limiting the portion of worker earnings that are actually insured.   This dichotomy between payroll that is assessed and what is actually insured is not well understood.  Even in Canada where there is an explicit statement in most provinces regarding insurable earnings, many workers will have earnings above limits for benefits leaving a potentially large portion of earnings uninsured.  It is not just that the compensation rate limits the percentage of earnings covered by workers’ compensation temporary or permanent benefits; caps on weekly benefits payable effectively limit insured payroll.  Such limits, of course, control costs but may leave many workers shocked when they have to access workers’ compensation only to learn they are under insured relative to their expectations.  More on that in a future post.
