Handling Partial Reimbursements for Benefits: 2026 Guide

Health Reimbursement Arrangements (HRAs), especially the Individual Coverage HRA (ICHRA), are changing the game for employee health benefits. Instead of a one size fits all group plan, an ICHRA gives companies the flexibility to offer tax free allowances for employees to buy their own health insurance. With reports showing triple digit growth in ICHRA adoption since 2020, it’s clear that employers value the cost control and flexibility.

But with this new freedom comes new administrative questions. One of the most common challenges is learning the rules around handling partial reimbursements for benefits. What happens when an employee joins mid year or leaves before the plan year ends? How do you ensure every claim is legitimate?

Handling partial reimbursements for benefits correctly involves three core principles: prorating allowances based on an employee’s start and end dates, requiring documented proof for every expense, and adhering strictly to the rules outlined in your plan documents. This guide breaks down the entire process, ensuring you can manage your HRA compliantly and efficiently for a smooth experience.

Setting the Rules: Your HRA Plan Document

The foundation of any successful HRA is a solid plan document. This is a formal, legally required document that acts as the rulebook for your benefits plan. It needs to clearly define how everything works, from eligibility to the claims process.

Defining Allowances and Claim Procedures

Your plan document must spell out the specific monthly reimbursement allowance for each employee or employee class. For example, you might offer full time staff $500 per month and part time staff $300 per month. These amounts are locked in for the plan year. A critical rule to remember is that you generally cannot change HRA allowance amounts mid year.

The document also outlines:

• Eligible Expenses: Will you reimburse only insurance premiums, or will you also cover other qualified medical expenses like copays and prescriptions? You decide this when you set up the ICHRA.

• Claim Submission Process: It should detail how employees submit claims, what proof they need to provide, and any deadlines for submission. This ensures a consistent and fair process for everyone.

• Compliance Language: As a group health plan, the document needs to include standard ERISA provisions, COBRA rights, and appeal procedures.

The Employee Side: Submitting a Reimbursement Request

Once the plan is in place, the reimbursement process begins with the employee. Unlike traditional insurance where a provider bills the insurer, an HRA requires the employee to initiate the request.

The typical workflow involves the employee gathering proof of an expense, like a premium invoice or a doctor’s bill, and submitting it through a designated system. Most modern HRAs use a secure online portal where employees can upload documents, track their allowance balance, and check the status of their claims.

The Claim Substantiation Requirement

This brings us to a crucial IRS rule: the claim substantiation requirement. This means employees must provide proof that an expense is for a qualified medical cost and that they had eligible health coverage when the expense occurred.

• Proof is Mandatory: An HRA cannot legally reimburse any expense unless the employee provides documentation. Simply taking their word for it is not enough.

• No Shortcuts: The IRS has been very clear that “honor system” methods or random spot checks are non compliant. Every single claim must be verified with legitimate documentation.

• Maintains Tax Free Status: This verification process is what allows HRA reimbursements to be tax free for both the employer and the employee.

Platforms like SimplyHRA make this easy by allowing employees to upload photos of receipts directly from their phone. The system can even help verify that an employee’s insurance plan meets Affordable Care Act (ACA) Minimum Essential Coverage (MEC) requirements, simplifying compliance.

The Admin Side: Review, Approval, and Payment

After an employee submits a claim, it’s up to the employer or a third party administrator (TPA) to review and approve it. This step is a critical checkpoint for compliance.

The Review and Approval Workflow

The reviewer checks each claim against the plan rules to confirm:

1. The expense is an eligible category.

2. The documentation is sufficient and matches the request.

3. The employee was covered by the HRA and had valid insurance on the date of service.

4. The employee has enough allowance remaining to cover the reimbursement.

Many employers outsource this task to a TPA or HRA software to ensure consistency, maintain employee privacy (HIPAA), and reduce administrative workload. An automated system can flag issues instantly, so a human reviewer only needs to look at exceptions. Effective handling partial reimbursements for benefits starts with a consistent approval process.

Reimbursement Mechanisms: Payroll vs. Direct Payment

Once a claim is approved, it’s time to pay the employee. There are two primary methods:

• Payroll Integration: The reimbursement amount is added to the employee’s next paycheck as a non taxable line item. This keeps payments consolidated, but it requires careful setup in your payroll system to ensure it isn’t taxed. Many find this the cleanest approach for handling partial reimbursements for benefits.

• Direct Payment: The payment is sent outside of payroll via a company check, ACH transfer, or a benefits debit card. This method can be faster, as it isn’t tied to the payroll schedule. Direct deposit is particularly efficient, speeding up the process for employees.

Modern platforms often provide the best of both worlds. For instance, SimplyHRA can trigger reimbursements automatically through integrated payroll systems or offer a pre funded debit card, giving employers and employees flexibility.

Navigating Nuances in HRA Reimbursements

Things get more complex when employees don’t stay for the entire plan year. This is where mastering the art of handling partial reimbursements for benefits becomes essential.

Pro-Rating Allowances for Partial Year Coverage

If an employee is hired mid year or becomes eligible partway through, their allowance should be prorated. ICHRAs are typically offered on a monthly basis, which makes this simple. For rollout steps and reminders, use our ICHRA onboarding checklist for new employer customers.

For example, if the annual allowance is $6,000 ($500 per month) and an employee starts on July 1, they are eligible for the monthly allowance for the remaining six months of the year, totaling $3,000. They don’t receive the full year amount. This method of handling partial reimbursements for benefits ensures fairness for all employees. For some HRAs like the QSEHRA, prorating the annual limit is not just a best practice, it is a legal requirement.

Disallowing Reimbursement After Coverage Termination

The rules are just as clear when an employee leaves. HRA eligibility is tied directly to active employment and active health insurance coverage.

If an employee terminates their employment or their insurance policy lapses, their HRA reimbursements must stop immediately. An HRA cannot reimburse any expenses incurred after the date coverage ends. For instance, if employment ends June 30, a doctor’s visit on July 1 is not eligible. This is a core principle of handling partial reimbursements for benefits. Most plans include a “run out” period, which gives former employees a short window (e.g., 60 days) to submit claims for expenses that occurred before their termination date.

Staying Compliant: Recordkeeping and Reporting

Properly handling partial reimbursements for benefits doesn’t end when the money is paid. Maintaining accurate records and fulfilling reporting duties are essential for compliance.

Employers must keep an audit trail for every reimbursement, including the employee’s request, the supporting documentation, and proof of approval. The IRS reiterated the importance of substantiation and recordkeeping in a 2023 memo, signaling that enforcement is a priority.

Key reporting requirements can include:

• Form W-2: Employers with a QSEHRA must report the permitted benefit on each employee’s W-2 in Box 12 using code FF.

• Forms 1094-C and 1095-C: Applicable Large Employers (ALEs) offering an ICHRA must report the offer of coverage to the IRS to show they complied with the employer mandate.

• Form 720: HRAs are subject to the Patient Centered Outcomes Research Institute (PCORI) fee, which is filed and paid annually using this form.

Managing these details manually can be a major headache. Using a dedicated HRA platform can automate much of this, generating audit ready reports and simplifying year end tax filings—see our healthcare compliance guide for what to include.

Frequently Asked Questions About Handling Partial Reimbursements for Benefits

1. Can we give a new employee a lump sum to “catch up” on their HRA allowance?

No, this would likely violate the rule against changing allowance amounts mid year. Allowances are earned monthly. The correct method for handling partial reimbursements for benefits for new hires is to provide the standard monthly amount for each month they are eligible.

2. What happens if an employee submits a claim for more than their remaining allowance?

The HRA should only reimburse up to the available balance. For example, if an employee has $100 left and submits a $150 claim, you would approve a partial reimbursement of $100. Most HRA software manages this automatically.

3. Do we have to offer COBRA for our ICHRA?

If your company has 20 or more employees and is subject to federal COBRA, you generally must offer COBRA continuation for the ICHRA. A terminated employee could elect to continue the HRA, but they would have to pay up to 102% of the HRA’s value out of pocket.

4. How long do we need to keep HRA reimbursement records?

It’s a best practice to keep all plan documents, employee notices, claim submissions, and substantiation records for at least seven years to be safe in the event of an audit by the IRS or Department of Labor.

5. What is the easiest way to manage prorating and termination rules?

Using an HRA administration platform is by far the easiest way. Software like SimplyHRA automates allowance calculations for new hires and properly cuts off eligibility upon termination, ensuring the complex rules around handling partial reimbursements for benefits are followed correctly every time.
