RATE OF PAY TEST

Updated July 20, 2025

Rate of Pay Test – Affordable Care Act Compliance Tool

In plain language: The rate of pay test is a method used by employers to decide if the health insurance they provide is affordable for their employees, based on their wages. It's a part of how companies adjust to the Affordable Care Act rules. 

Technical definition: Under the ACA affordability provisions, the rate of pay safe harbor allows applicable large employers (ALEs) to gauge the affordability of their medical plan based on an employee's hourly rate of pay or monthly salary. This provision is one of three safe harbor methods and is often used to simplify ACA affordability calculations for full-time employees. 

Understanding the rate of pay test is key to navigating the challenges of hr compliance, particularly when administering employee benefits under the Affordable Care Act. A clear grasp on this concept prevents IRS penalties and supports a well-rounded contribution strategy.

What Is Rate of Pay Test in Insurance?

The rate of pay test is a provision under the ACA regulations that allows companies to determine the affordability of their health coverage based on the wages of full-time employees. The calculation is made for each hourly employee based on the employee’s lowest hourly wage during the calendar year, multiplied by 130 hours (the benchmark for full-time status under ACA), and cannot exceed the ACA affordability percentage. 

For salaried employees, affordability is established based on the employee's monthly salary. The ACA affordability calculation often plays a crucial role during ACA reporting, especially while filling form 1095-C. 

Note that the rate of pay test does not consider changes to pay rates within a plan year, increasing its complexity. While the rate of pay test provides a practical tool for affordability test, it's essential to always review state-specific regulations and consult with a professional for complete insurance compliance.

Common Questions About the Rate of Pay Test

How does the rate of pay test affect payroll administration? 

The rate of pay test can make payroll administration more complex since healthcare premium calculations must align with employee wages while not exceeding the ACA affordability percentage. This means careful monitoring of hourly rates and monthly salaries is necessary to ensure healthcare premiums remain in line with ACA affordability guidelines. 

What triggers a penalty under the ACA’s employer mandate? 

A penalty can be invoked if affordable coverage isn’t offered to a minimum of 95% of full-time employees. This is defined as meeting the minimum value and affordability threshold, determined through methods such as the rate of pay test. An affordability determination that exceeds the affordability percentage can lead to a "B" penalty. 

What is the distinction between the rate of pay safe harbor and the W-2 wages safe harbor? 

The rate of pay safe harbor calculates affordability based on an employee's hourly wage or monthly salary. Contrastingly, the W-2 wages safe harbor considers the amount in Box 1 of an employee's W-2 form. Deciding between safe harbor methods often depends on the compensation levels and structures, including the distinction between hourly employees and non-hourly employees. 

How does the affordability test apply to commissioned employees? 

Commissioned employees complicate the rate of pay test as their income might fluctuate significantly. Here, employers might choose to use the W-2 safe harbor or federal poverty line safe harbor instead of the rate of pay test.

Real Claim Examples Involving the Rate of Pay Test

Scenario 1: A company failed to track changes in their employees' hourly rates across a calendar year. Due to a mid-year pay raise, their employee contribution exceeded the affordability threshold. Consequently, they faced IRS penalties for failing the rate of pay test, leading to significant costs and a review of their ACA affordability compliance strategy. 

Scenario 2: A larger company used the rate of pay test to calculate affordability for their many hourly employees. Despite comprehensive tracking and an efficient payroll administration system, they overlooked annual changes in the ACA affordability percentage. This miscalculation led to them unknowingly violating the employer mandate and facing expensive penalties. 

Scenario 3: While transitioning many of their full-time employees to salaried roles, a company made the mistake of calculating affordability based on the prior hourly rate rather than the current monthly salaries. This ill-advised move led to overestimation of the contribution amounts, leading to errors in the affordability test and potential penalties had it not been rectified in time. 

Limitations and Common Mistakes

    The rate of pay test does not account for changes in pay rates during a plan year. 
    Misinterpretation of rules surrounding the rate of pay test can lead to serious ACA non-compliance issues. 
    Neglecting to adjust for pay changes that occur mid-year can lead to incorrect ACA affordability calculations. 
    Failing to keep up with annual changes in ACA affordability percentages can lead to costly errors.
