Year-End HSA Checklist

As the year winds down, take these steps to maximize your HSA benefits before December 31.

1. Max Out Your Contributions

2026 Limits:

• Individual: $4,400
• Family: $8,750
• Catch-up (age 55+): +$1,000

Check your year-to-date contributions and calculate how much room you have left. If you contribute through payroll, you may need to act quickly—some employers require changes 1-2 pay periods in advance.

Can't max out through payroll? You can make direct contributions to your HSA until April 15, 2027 for the 2026 tax year. You'll claim the deduction on your tax return.

Use our Growth Calculator to see exactly how much you'll save by contributing more.

2. Review Your Receipts

If you're saving receipts for future reimbursement, now is a good time to verify:

• All receipts are properly documented with date, provider, and amount
• Expenses are HSA-eligible (see our Eligible Expenses guide)
• You have backup documentation (EOBs, itemized bills) for larger expenses

Using HSA Vault? Log in to review your stored receipts and ensure nothing is missing from this year.

3. Check Your Unreimbursed Balance

One of the most powerful HSA strategies is paying for medical expenses out-of-pocket and letting your HSA grow tax-free. Track what you could reimburse yourself for later.

Consider reimbursing now if:

• You need cash for holiday expenses or emergencies
• You have a large expense and want to reduce taxable income this year
• Your HSA isn't invested and isn't earning meaningful returns

Consider waiting if:

• Your HSA is invested and growing
• You don't need the cash
• You want to maximize long-term tax-free growth

4. Verify Your HDHP Coverage

Your HSA contribution eligibility depends on having qualifying HDHP coverage. Confirm:

• You were covered by an HDHP for each month you want to contribute
• You weren't covered by a disqualifying plan (like a full FSA or non-HDHP spouse plan)
• If coverage changed mid-year, you may need to prorate your contribution limit

Changing plans during open enrollment? Make sure your new plan qualifies. Our Plan Optimizer can help you compare options.

5. Use It or Lose It? Not with HSAs

Unlike FSAs, HSA funds never expire. You don't need to spend down your balance by year-end. But you should:

• Verify your HSA provider isn't charging excessive fees
• Consider investing your balance if it exceeds 3-6 months of typical medical expenses
• Review your beneficiary designation

6. Gather Tax Documents

You'll need these for your tax return:

• Form 5498-SA: Shows your total contributions (sent by your HSA custodian)
• Form 1099-SA: Shows distributions (if you reimbursed yourself)
• Receipts: Keep records of all expenses you paid from your HSA

If you made direct contributions (not through payroll), you'll report them on Form 8889.
