Proof, attestation, timing, and the two ways your premium actually gets paid. This is the part people get wrong.
The allowance is the promise. Reimbursement is the mechanics. Most ICHRA frustration comes from this step, so here's exactly how it usually works.
| Model | How it works | What you do |
|---|---|---|
| Reimbursement | You pay the carrier from your own account. You upload proof. The employer (or its administrator) pays you back, typically through payroll or direct deposit. | Keep the premium invoice or receipt every month; submit it by the deadline. |
| Direct pay / premium advance | The administrator pays the carrier on your behalf, or your employer fronts the allowance. You may see the employee share deducted from your paycheck. | Confirm enrollment once; mostly hands-off after that. |
Your employer's notice or administrator's app will tell you which model applies. Many use a mix — direct pay for premiums, reimbursement for everything else.
Before your first reimbursement each plan year, you'll generally be asked to attest — confirm in writing — that you and anyone else being reimbursed are enrolled in individual coverage or Medicare for the coming year. It's usually a short online form. Missing it typically holds up every reimbursement after it.
For each reimbursement, you'll typically provide one of:
Many administrators let you submit once and set the premium to recur monthly. Ask.
| Expense | Reimbursable? |
|---|---|
| Individual plan premium — Marketplace or off-Marketplace | Generally yes |
| Medicare Part B, Part D, Advantage, Medigap premiums | Generally yes |
| Family members' premiums, if they're on individual coverage | Generally yes, if included in your allowance |
| Deductibles, copays, prescriptions, dental, vision | Only if your ICHRA is set up to reimburse them |
| Spouse's employer group plan premium | Generally no |
| Short-term or limited-benefit plans, health-sharing ministries | Generally no |
| COBRA from a previous employer, TRICARE-only, Medicaid | Generally no |
