Why a Year-End Review Pays Off
The final weeks of the calendar year are one of the few windows where several consequential financial deadlines converge. Contribution limits reset. FSA balances expire. Open enrollment closes. Tax withholding shortfalls that have been quietly accumulating all year are still fixable — but only if you act before December 31.
Most households don't miss these deadlines because they don't care. They miss them because everyday life gets in the way and nobody sends a reminder. This checklist is that reminder. Work through it section by section and you'll head into the new year with a clearer picture of where you stand.

This Is General Information, Not Personal Advice
This checklist provides general financial education for informational purposes only. It is not personalized financial, tax, or legal advice. Your situation depends on your income, household composition, employer plan rules, and state law. Consult a qualified financial adviser, CPA, or attorney before making decisions specific to your circumstances.
What You'll Need Before You Start
Before working through the checklist, gather a few key documents to avoid unnecessary back-and-forth:
- Your most recent pay stub (year-to-date figures are on it)
- Last year's tax return for reference
- Login credentials for your employer benefits portal and retirement account
- Statements for any credit cards, loans, or savings accounts you want to review
- Receipts or records of charitable donations made this year
Having these in one place — even just a folder on your desktop — keeps the process from stalling. Most of the tasks below take only a few minutes once the right information is in front of you.

Working Through the Checklist
The six groups below cover the areas where year-end timing matters most. You don't have to tackle them in order, but tax and benefits items tend to have the hardest deadlines, so start there if time is limited.

FSA Funds Can Vanish at Year-End
Most Flexible Spending Accounts operate on a strict use-it-or-lose-it basis. Any unspent balance on December 31 is typically forfeited back to your employer — you do not get a refund. Check your balance now and stock up on eligible expenses such as prescription refills, glasses, or approved over-the-counter items before the deadline.
Missed Open Enrollment Is Costly
If you skip your employer's open enrollment window without making an active election, you may be automatically re-enrolled in last year's plan — which may no longer fit your needs or budget. Missing the window entirely can lock you out of making changes until the next enrollment period unless you experience a qualifying life event.
Once you've completed the tax, benefits, and retirement sections, the budget and credit items are valuable but more flexible — many of those tasks can carry into January without penalty. Our annual credit and savings health check walks through the credit review steps in more detail if you want a deeper dive.
After You've Checked the Boxes
Completing this checklist isn't the finish line — it's a reset point. Once you've confirmed your withholding, locked in your benefits elections, and reviewed where your money went this year, you're in a much stronger position to set realistic targets for the months ahead.
A few follow-up moves worth scheduling:
- Update your budget for the coming year using what you learned from this year's actual spending. See budgeting basics for simple frameworks.
- Note upcoming renewal dates for insurance policies so you have time to review coverage before auto-renewing. Our auto policy review checklist is a useful companion.
- Flag any tax form questions now so you're not scrambling in February. Our plain-language tax form reference explains the forms most households encounter.
