ICHRA plan document: what it is and why you need one

What the plan document is

An ICHRA plan document is the formal written agreement that establishes your ICHRA under IRS and Department of Labor rules. It''s the governing rulebook for the arrangement — defining who''s eligible, how much they get, what''s reimbursable, and how claims are handled. Without it, the ICHRA isn''t properly established and reimbursements can lose their tax-free status.

What it must include

• Which employees (classes) are eligible
• The reimbursement amounts (allowances) by class
• What expenses are reimbursable (premiums and/or medical expenses)
• How employees substantiate coverage and claims
• How and when reimbursements are paid
• Plan year, effective dates, and required legal provisions

Plan document vs. employee notice

These are two different things people often confuse. The plan document is the governing rulebook — the legal foundation of the arrangement. The employee notice is the communication you send employees explaining how the benefit works and how it affects their ACA subsidy. You need both: the document establishes the plan; the notice informs employees.

Why it matters

Without a compliant plan document, reimbursements can lose their tax-free status and the arrangement may not hold up to scrutiny. The document is what separates a real, compliant ICHRA from simply giving employees money — it''s the legal basis for the entire tax-free benefit.

How to get one

You don''t draft this yourself. An ICHRA administrator or broker generates a compliant plan document (and the matching employee notice) as part of setup. They keep the language current as rules change, so you''re not tracking regulatory updates on your own.

Keeping it updated

The plan document should reflect your current design — allowances, classes, and what''s reimbursable — and stay aligned with current regulations. When you change the allowance or add a class, the document is updated accordingly. Your administrator or broker maintains it across plan years.

Common mistakes

• Running an ICHRA with no formal plan document (jeopardizes tax-free status).
• Confusing the plan document with the employee notice — you need both.
• Letting the document fall out of date with your actual design.
• Trying to draft it yourself instead of using an administrator or broker.

Who needs to see the plan document

The plan document is the legal backbone, and employees are entitled to the information in it. In practice you provide a summary to employees and make the full document available on request. Because an ICHRA is an ERISA plan in most cases, proper documentation and disclosure are not optional.

How classes and allowances appear in it

Your plan document is where the specifics live: which employee classes are eligible, the monthly allowance for each, whether unused amounts carry over, and how substantiation works. If you ever change allowances or classes, the document has to be updated to match.

DIY vs. professional plan documents

Free templates exist, but a plan document that is vague, outdated, or misaligned with how you actually run the ICHRA can undermine the tax treatment and create compliance exposure. Most employers use a broker or administrator to produce and maintain a compliant document.
