December is the accountant’s month, and it should be yours too. The year-end portfolio review is the annual tune-up that keeps your investments aligned with your goals, your taxes under control, and your plan sane. It takes an hour, and it answers the questions that quietly nag all year: am I on track, am I paying too much, and is my money where I think it is? Here is the checklist to run before January.
Check Your Asset Allocation
Start with the big picture. Compare your actual portfolio allocation, stocks, bonds, cash, and alternatives, against your target. Markets move, and a strong stock year can silently push your stock allocation far above your target, which means more risk than you agreed to take. If you are more than five percentage points off, rebalance by selling what grew and buying what shrank, or by directing new contributions to the laggards.
Recheck the allocation itself too. If your life changed this year, a new job, a baby, a marriage, an inheritance, your risk tolerance may have changed, and your target should change with it. The review is the moment to decide, not in the middle of a market panic.
Harvest Losses Before the Deadline
December is the last chance to realize capital losses for this tax year. Review your taxable accounts for positions trading below your cost basis, sell any losers you are comfortable replacing with a similar fund, and bank the losses to offset gains or up to $3,000 of ordinary income. Watch the wash sale rule: do not buy the same security within 30 days, and be careful about the same fund in your retirement accounts.
If you have unrealized gains you want to take, either to rebalance or to use up harvested losses, the year-end window lets you do both in one transaction and net them on your tax return.
Audit Your Fees and Your Contributions
Look at every fund’s expense ratio and any account fees you paid this year. High fees are the one portfolio flaw you can fix instantly, and the year-end review is the natural moment to switch to lower-cost options, especially inside retirement accounts where the switch is tax-free. If you are paying an advisor, confirm the fee is competitive and the advice is worth it.
Then check the limits. Are you on track to max out your 401(k), IRA, and HSA for the year? December is often the last month to adjust payroll deferrals for the current year, and it is the month to set next year’s increase. Small annual increases compound into large balances, and the year-end is when they get set.
Review Beneficiaries, Insurance, and Documents
Beneficiary designations override wills, which is why outdated ones cause so much heartbreak. Check every account, retirement plan, life insurance policy, and payable-on-death account, and update after any marriage, divorce, birth, or death in the family. If you have no beneficiaries listed, that is a problem; unlisted accounts go through probate.
Review your insurance: life, disability, home, and auto, to confirm coverage still matches your life. Then check your emergency fund is at the target level and parked in a high-yield account. Finally, look at your estate basics, a will or trust, a durable power of attorney, and a healthcare directive. If you do not have them, the new year is the time to fix that.
Write Down What Changed
End the review by writing a one-page summary: your current allocation, what you rebalanced, the losses you harvested, your contribution plan for next year, and any open tasks. File it with your tax documents. Next December, you will thank yourself for the record. The year-end review is not about predicting the market, which no one can do. It is about making sure your money matches your plan, your plan matches your life, and the tax code works for you instead of against you.
