Do HSA/FSA Reimbursement Claims Require a Tax ID/TIN?

When submitting an HSA or FSA reimbursement claim, you might sometimes see a request for a Tax ID (TIN). This is a common point of confusion-here’s what you need to know.

• HSA/FSA claims do not require a Tax ID/TIN.

• If you are being asked for a TIN, you are most likely filing through your healthcare provider’s portal rather than your HSA/FSA provider’s portal.

• Your HSA/FSA provider has its own dedicated claim submission system.

When filing through your HSA/FSA provider, claims usually require only:

• An itemized receipt

• A Letter of Medical Necessity (LMN) (if applicable)

No Tax ID/TIN is required.

1. Confirm your HSA/FSA provider.
   Examples include: Fidelity, HealthEquity, Optum, etc.

2. Log in to their dedicated HSA/FSA portal.
   This is where you should submit your claim.

3. Upload your documents.

   • Itemized receipt

   • LMN (if required)

• If you’re asked for a Tax ID/TIN, double-check that you’re not filing through your health insurance company’s portal instead of your HSA/FSA provider’s portal.

• If you’re not sure who your HSA/FSA provider is:

  • Ask your employer’s HR/benefits team

  • Check with the card issuer

  • Or contact Truemed Support and we’ll help point you in the right direction

Bottom line: HSA/FSA reimbursement claims never require a Tax ID/TIN. Always file through your HSA/FSA provider’s portal for a smooth process.
