An FSA and an HSA can both help pay eligible expenses, but retirement does not affect them in the same way. First identify the account's exact name and administrator. A balance displayed on a dashboard does not by itself establish which expenses remain reimbursable.
Identify each account before making a spending plan
OPM distinguishes Health Care and Limited Expense Health Care FSAs from Dependent Care FSAs after separation or retirement. HCFSA and LEX HCFSA participation ends at separation; eligible earlier expenses may still be submitted under the claims rules, while later expenses are not reimbursable. DCFSA balances follow different rules for eligible expenses through the remaining calendar year. Obtain the administrator's applicable conditions and submission deadline.
An HSA is a separately owned account. Retaining or spending existing HSA funds is a different question from eligibility to make new contributions. Medicare enrollment affects contribution eligibility, including potential retroactive Part A coverage. Publication 969 reviewed for this draft is the 2025 edition; verify current-year tax changes before applying dollar limits or eligibility exceptions.
Make a four-date worksheet
| Account | Contribution end | Expense eligibility cutoff | Claim submission deadline | Confirmation source |
|---|---|---|---|---|
| Health Care FSA | Ask payroll | Confirm separation rule | Obtain current instructions | FSA administrator |
| Limited Expense FSA | Ask payroll | Confirm separation rule | Obtain current instructions | FSA administrator |
| Dependent Care FSA | Ask payroll | Confirm post-separation conditions | Obtain current instructions | FSA administrator |
| HSA | Review eligibility by month | Qualified-expense and account rules | Tax-record requirements differ | Custodian and tax adviser |
Do not substitute the deadline to submit a receipt for the last date an eligible expense can occur. Put both dates on the calendar. Ask how the program handles a service spanning several dates before assuming the invoice date controls.
Reconcile payroll and Medicare records
List employer contributions and employee deductions separately. Bring the proposed retirement date, any Social Security application date and the confirmed Medicare effective dates to the HSA review. Ask who will stop contributions and how to identify amounts already credited for an ineligible month.
Do not assume that keeping a high-deductible plan automatically permits HSA contributions after Medicare enrollment. Likewise, do not assume that stopping payroll deductions resolves every contribution issue. Have a qualified tax adviser explain any correction process for the actual record.
Organize receipts without creating a new data exposure
Keep itemized receipts and reimbursement records in personal files. Mark whether another account or insurer has already reimbursed an expense so the tax review can identify duplicate reimbursement questions. Send medical and dependent-care details only through the administrator's appropriate secure channel.
For an unresolved claim, record the service date, amount claimed, submission receipt and administrator response locally. A public website inquiry can ask how to prepare for retirement without including diagnoses, dependent identifiers or account numbers.
Confirm which employer program applies
Postal benefits require a separate check. Do not assume every postal flexible spending arrangement is FSAFEDS merely because the medical plan is PSHB. Ask the employer to identify the correct program and current administrator.
Use the Medicare timing worksheet and FEDVIP review for connected questions. This guide does not determine tax eligibility, authorize reimbursement or replace current account instructions.
