Defense contractors carry contract rules, mixed workforces and cost accounting that most employers do not. An ICHRA has to fit all three.
For a defense contractor, an individual coverage HRA means allowances set class by class, for example salaried engineers versus hourly technicians, with the option to differ by site. The real effort lies in drawing the classes, meeting contract benefit requirements and understanding how benefit costs end up in the rates billed to the government.
Why defense contractors look at an ICHRA.
Salaried and Hourly Classes
Salaried engineers and program managers and hourly technicians or assemblers fall into different permitted classes. Everyone in a class receives the same allowance.
Each Site Can Be Its Own Rating Area
Allowances can differ where sites sit in separate rating areas. The calculator prices each site.
Union Employees Can Be a Separate Class
Workers covered by a specific collective bargaining agreement may form their own class. Have counsel read each agreement before deciding.
Contract Awards Change Headcount
Contract awards and recompetes push headcount up and down. A fixed monthly allowance for each class tells you ahead of time what each additional hire will cost in benefits.
A Waiting Period for New Hires
Allowances can be held back for new hires for as long as 90 days, so long as the same waiting period covers the entire class.
A Different Option from Group Health
An ICHRA may take the place of the group plan, or it may operate next to it for chosen classes. Participation and cost determine the better fit.
The contractor issues that decide whether it works.
Affordability for Larger Contractors
Once a contractor reaches 50 full-time equivalent employees, the coverage it offers has to pass the affordability test. Test every class individually and not only the average.
Contract Benefit Requirements
Some federal service contracts require a set health and welfare benefit per hour for covered employees. Confirm with counsel whether an ICHRA allowance can satisfy the requirement.
Plan Choice Near Each Site
Each employee shops for an individual plan in his or her own market, so look at carriers and networks close to every site.
Employee Shopping Experience
Engineers and technicians seldom spend time shopping for benefits, so someone must guide them through the marketplace and the steps for reimbursement.
Notice and Timing
Eligible staff must get written notice 90 or more days before the plan year, so begin counting at the effective date.
Rates and Cost Accounting
Benefit costs often flow into indirect rates charged to the government. Review any change with your accounting and contracts staff before it takes effect.
What to settle before moving a contractor to an ICHRA.
Which contracts carry benefit requirements?
List every contract and any health and welfare clause or wage determination.
Which employees are in which class?
Job title is not a permitted class. Sort engineers, technicians and staff by full-time, part-time, salaried or hourly status.
Which employees are covered by an agreement?
Before you draw class lines, make a list of every bargaining agreement.
Who helps employees buy a plan?
Assign someone to answer questions during the first enrollment, and tell people when that person is available.
Does every class pass affordability?
Every class must pass the test itself; one class that fails is a compliance problem even when the rest pass.
How will the change affect rates?
Ask accounting how the allowance will appear in indirect rates before choosing a start date.
The questions defense contractors ask about ICHRAs.
Can a defense contractor give engineers and technicians different allowances?
Yes, if they fall into different permitted classes such as salaried and hourly or full-time and part-time. Job title alone is not a class, so counsel should review the definitions.
Does an ICHRA satisfy a contract health and welfare requirement?
Some federal service contracts require a set health and welfare benefit. Department of Labor guidance we reviewed does not address ICHRAs, so counsel should confirm whether an allowance can count.
How do benefit costs affect government billing rates?
Benefit costs often flow into indirect rates, so review the change with accounting and contracts staff before it starts.
Can union employees be a separate class?
Yes. Staff covered by one collective bargaining agreement can be placed in a class by themselves, but counsel should look at each agreement first.
Does a new hire have to wait before the allowance starts?
A waiting period is allowed for up to 90 days, applied the same way to everyone in the class.
What notice do employees need?
Send eligible employees written notice no later than 90 days ahead of the plan year, counting from the effective date.
Should a contractor keep its group plan?
Some contractors retain the group plan for one class and put others on an ICHRA; others switch completely. Cost, participation and class design decide it, and we model both.
