When you receive unsubstantiated claims notices from TASC, the Flexible Spending Account (FSA) Administrator, substantiate, substitute, or repay your unsubstantiated claims, preferably by December 31. This page includes information on how to resolve your 2026 claims and a timeline of what will occur in 2027 if you do not resolve your claims timely.
Basics of Healthcare FSA Unsubstantiated Claims
If a health care FSA payment card transaction is not automatically substantiated, you will be notified of an “unsubstantiated claim” that needs to be resolved by substantiation, substitution, or repayment. You will receive notices about the unsubstantiated claim via the email address associated with your TASC account:
- 10 days after the transaction
- 40 days after the transaction
- 70 days after the transaction
If your claims are not resolved within 85 days, your payment card will be deactivated (until your claims are resolved). Check the junk folder in your email for these notices. If you do not have an email address associated with your TASC account, the notices will be sent via U.S. Mail.
The FSA administrator sends these notifications for every health care FSA unsubstantiated claim throughout the year.
Resolving Your Unsubstantiated Claims
To avoid the payroll withholding process, 2026 healthcare FSA claims must be resolved by December 31, 2026. To resolve a claim, you should do one of the following:
- Substantiate the original claim with documentation. Documentation may include:
- Explanation of benefits (EOB) provided by your health or dental insurance carrier (recommended when available)
- Itemized statement
- Substitute the original claim with another eligible expense. A substituted claim cannot be a claim previously submitted, and must be for the 2026 plan year.
- Repay the amount of the claim directly to TASC. To do so, contact TASC to walk you through this option.
You may submit documentation to resolve your claims using the TASC mobile app or the TASC website.
Inactive Employees
If you are no longer an active employee:
- You are responsible for updating your email and mailing address directly with TASC.
- If you do not resolve an unsubstantiated claim, it will be converted to business debt.
