December contains more financial decisions than any other month. Most people navigate it reactively. Here's a proactive checklist of everything worth addressing before January 1.
Debt Decisions
- Make any final extra payments to reach a year-end milestone
- Call any card issuers where a rate negotiation hasn't been tried this year
- Check whether any balance transfer opportunities exist before new card promotions reset
- Pre-commit your tax refund to the highest-rate balance
Benefits and Insurance
- Confirm open enrollment decisions are finalized and elected benefits start January 1
- Use any remaining FSA balance on qualified expenses before year-end forfeiture
- Review life and disability insurance coverage for adequacy
- Check auto insurance renewal terms if they fall in December or January
Retirement and Savings
- Calculate remaining 401(k) contribution room (2026 limit: $23,000 or $30,500 for 50+)
- Confirm contributions are maximizing employer match
- Make any final IRA contributions for the tax year if applicable
Tax Moves
- Make charitable contributions before December 31 if claiming deductions
- Harvest any investment losses to offset gains before year-end
- Estimate your tax liability and adjust withholding or make a Q4 estimated payment if needed
Administrative
- Update your emergency contact information with all financial institutions
- Review beneficiary designations on retirement accounts and life insurance
- Download the year's financial statements if you keep records for tax purposes
- Set up any new automation for January (new payment amounts, new savings transfers)
