As the world increasingly embraces green energy, renewable energy companies have been at the forefront of promoting sustainable practices. To encourage this transition, the government offers a variety of tax breaks and incentives, including the Inflation Reduction Act (IRA). There are many incentives within the IRA, but to qualify for most of them you have to follow prevailing wage and/or apprenticeship requirements. For companies that have never before encountered prevailing wage work, this can be daunting. This guide provides a brief overview of the Inflation Reduction Act’s prevailing wage requirements and what that means for your renewable energy company.

Inflation Reduction Act 101

The Inflation Reduction Act is a legislative initiative aimed at mitigating the adverse effects of inflation on the economy. Under the act, companies may receive certain increased tax benefits by meeting prevailing wage and apprenticeship requirements.

By statute, the prevailing wage and apprenticeship requirements generally apply to qualifying facilities where construction begins 60 days or more after the U.S. Department of the Treasury and the Internal Revenue Service (IRS) published guidance on those requirements.

New Renewable Energy Provisions

On November 30, 2022, this guidance was published, marking the beginning of the 60 days. This means that to receive increased incentives, you must meet the prevailing wage and apprenticeship requirements for facilities where construction begins on or after January 29, 2023. Prevailing wage and apprenticeship provisions apply to the following programs under the IRA:

  • Alternative Fuel Refueling Property Credit
  • Production Tax Credit
  • Credit for Carbon Oxide Sequestration
  • Credit for the Production of Clean Hydrogen
  • Clean Fuel Production Credit
  • Investment Tax Credit
  • Advanced Energy Project Credit
  • Energy-Efficient Commercial Buildings Deduction

In addition, the Inflation Reduction Act’s prevailing wage provisions apply to the:

  • New Energy Efficient Home Credit
  • Zero-Emission Nuclear Power Production Credit

To take advantage of these programs, your company must follow prevailing wage provisions or prevailing wage and apprenticeship provisions.

Understanding Prevailing Wage Laws for Renewable Energy Projects

Federal prevailing wage laws were put in place to ensure fair compensation for workers on federally funded projects. This is for all federally managed construction including renewable energy projects. These laws fall under Davis-Bacon and Related Acts, and they mandate that workers on public works projects receive wages that are consistent with wages paid for similar jobs within the area.

Some states have their prevailing laws for state-funded projects. Companies that take on government projects must follow the requirements outlined in these laws to receive payment and stay compliant. This includes companies hoping to take advantage of the benefits offered under the Inflation Reduction Act. Let’s look at the basics of complying with federal prevailing wage laws.

Prevailing Wage Basics

Prevailing wage law can get complicated but complying with it comes down to the following actions:

  • Paying workers the correct prevailing wage and fringe benefits as determined by wage determinations published by the government.
  • Following record-keeping and reporting requirements for certified payroll.
  • Following apprenticeship requirements when applicable.

Keeping sufficient records to demonstrate laborers and mechanics were paid prevailing wage rates is key to obtaining your ability to qualify for any incentives under IRA. If you contract work out to subcontractors, they must also comply with these provisions to maintain your eligibility for incentives.

What workers qualify for prevailing wages?

Laborers and mechanics: Workers that perform work in trades and occupations that are primarily manual labor and skilled trades such as electricians, ironworkers, carpenters, and general laborers. Under IRA, this includes non-employees who perform this work on your behalf, including independent contractors who receive a 1099.

What workers do not qualify for prevailing wages?  

Administrative, clerical, architects, inspectors, and executive work are examples of work that is not included under “laborers and mechanics” and do not fall under prevailing wage requirements.

What are prevailing wage rates?

Prevailing wages are determined by the Secretary of Labor and refer to the wage listed for a specific classification of laborer or mechanic on the wage determination for the type of work AND geographic area. Classifications are job types such as electrician, carpenter, general laborer, and similar roles. Prevailing wages include basic hourly wage rates PLUS fringe benefits. The following wage determination shows the hourly and fringe rates for two types of electrical job classifications in Alaska. The full amount owed to workers performing this specific type of work is the amount in the Rates column added to the amount in the Fringes column.

What are fringe benefits under IRA?

Fringe benefits are in addition to the hourly prevailing wage rate. Fringe benefits can either be paid in cash and simply added to the hourly wage rate or paid through some types of benefits. Anything that is required by law, like workers’ comp or social security, does not count toward fringe benefits. This means fringes can be paid in cash or options such as:

  • Life insurance
  • Health insurance
  • Pension
  • Vacation
  • Holidays
  • Sick Leave

Cash is the most expensive way to pay fringe benefits because you pay more in payroll taxes, workers’ comp, and general liability. Fringe benefits paid through an eligible bona fide trust can save your company lots of money.

How do you find prevailing wage rates

The awarding agency will often provide you with the correct wage determinations for the project. However, there are other times when the wage determination is not provided, and you must find the correct prevailing wage for each work classification on your project. Either way, it is your responsibility to use the correct information, so you’ll always want to verify wage rates. The Department of Labor (DOL) publishes official wage determinations on SAM.Gov. This is the official government website for those who make, receive, and manage federal awards. If you go to the home page, you’ll need to select “Wage Determinations” to get started. You can also bookmark the following link to take you directly to the wage determination section. Once there, the following steps will help you locate wage determinations for your project:

Certified Payroll Basics and Renewable Energy

Certified payroll reports play a crucial role in demonstrating compliance with labor laws, particularly in the context of renewable energy projects. These reports, submitted to the Department of Labor (DOL) on a weekly basis, serve as detailed records outlining important payroll information. They provide evidence that all applicable laws, including prevailing wage requirements, are being adhered to throughout the duration of the project.

One of the most straightforward methods of meeting these reporting obligations is by utilizing form WH-347. This form facilitates the inclusion of a multitude of essential details pertaining to each worker, such as their pay rates, specific roles undertaken, and total hours worked. By meticulously documenting this information, renewable energy companies can ensure transparency and accountability in their payroll processes, thereby upholding legal standards and maintaining the integrity of their projects.

List of Certified Payroll Report Inclusions

They must include a great number of details on each worker’s pay, role, and time worked, including the following information:

  • Complete the legal name and an identifying number of each worker. This can be the last four of their SSN.
  • Work classification they worked under, which may be more than one.
  • All hours worked, including the day, date, straight time, and overtime hours.
  • Total hours worked for the week being reported on.
  • Rate of hourly pay. If more than one work classification is worked, this must be shown per each one
  • Gross amount earned
  • Payroll deductions and total of the deductions
  • Net wages paid for the week

Certified payroll reports are mandatory, time-consuming, and complicated. It is easy to make mistakes, especially if you’re new to them or using manual processes like hand-written timecards.
