Tax-Loss Harvesting and Capital Gains: Year-End Moves for Rochester Investors

Nobody enjoys looking at an investment that has lost money.
But if you hold investments in a taxable account, those losing positions have a use, and the window to put them to work closes on December 31.
Tax-loss harvesting is one of the more reliable year-end moves available to investors in Rochester, Greece, and Monroe County, and it is widely misunderstood.
The Basic Idea
When you sell an investment for less than you paid, you realize a capital loss.
Those losses are not wasted. They offset capital gains you realized elsewhere during the year, reducing the amount you are taxed on.
So if you sold one position at a healthy gain and another has been underwater for a while, selling the loser can cancel out part or all of the tax on the winner. Same portfolio, smaller tax bill.
What Happens When Losses Exceed Gains
This is the part many investors do not realize.
If your losses are larger than your gains, you can use up to 3,000 dollars of the excess to offset ordinary income, things like wages and business income, which are typically taxed at higher rates than capital gains.
And if you still have losses left over after that, they carry forward. There is no expiration. Unused losses roll into future years indefinitely, available to offset gains down the road.
That makes a bad year in the market considerably less bad. Losses banked now can shelter gains years from now.
Short-Term Losses Are Worth More
Not all gains and losses are created equal, and the ordering matters.
Investments held a year or less produce short-term gains, taxed at ordinary income rates. Investments held longer produce long-term gains, taxed at preferential rates that are usually meaningfully lower.
Losses are applied first against gains of the same type, short against short and long against long, before crossing over. Because short-term gains are taxed more heavily, a loss that offsets one is doing more work for you than a loss offsetting a long-term gain.
Worth knowing when you are deciding which positions to sell.
The Wash Sale Rule
Here is the rule that undoes careless harvesting.
If you sell an investment at a loss and buy the same or a substantially identical security within 30 days before or after the sale, the loss is disallowed. You do not get to claim it.
A few things people miss:
- The window runs both directions, 30 days before and 30 days after, so a purchase you made earlier in the month can spoil a sale
- It applies across your accounts, including purchases in an IRA
- Automatic dividend reinvestment can trigger it without you doing anything deliberately
- A spouse’s purchases can count as well
The disallowed loss is generally added to the basis of the replacement shares, so it is deferred rather than destroyed. Still, it defeats the purpose of the exercise this year.
The common workaround is to buy something similar but not substantially identical, which keeps you invested in the market while the window runs. Where exactly that line sits can be a judgment call, which is a good reason to talk it through rather than guess.
Do Not Let Taxes Drive the Investment
This deserves saying plainly.
Selling a good long-term holding purely to capture a tax benefit is usually a mistake. The tax saving is real, but it is a one-time benefit, and abandoning a sound position to get it can cost far more over time.
Tax-loss harvesting works best when it aligns with something you were considering anyway: rebalancing a portfolio that has drifted, exiting a position you no longer believe in, or trimming a concentrated holding.
Let the investment case come first. Then handle the timing in a tax-aware way.
Gains Are Worth Planning Too
Harvesting works in the other direction as well, and it gets far less attention.
In a year when your income is unusually low, perhaps a gap between jobs, a business downturn, or early retirement before Social Security begins, you may be able to realize long-term gains at a very low rate.
Deliberately taking some gains in a low-income year can reset your basis higher at little or no tax cost. This is a genuine opportunity that tends to go unnoticed precisely in the years when people feel least like thinking about taxes.
Watch the Calendar and the Paperwork
Two practical points.
First, the trade needs to happen by December 31 to count for this year. Do not leave it to the last day, particularly around holidays and shortened market sessions.
Second, check how your basis is being reported. Brokerages track cost basis, but if you have transferred accounts over the years, inherited shares, or reinvested dividends for a long time, the recorded basis is not always right. An incorrect basis means an incorrect gain or loss on your return.
How We Help Rochester Investors
The mechanics of harvesting are simple. Fitting it to your actual tax situation is where the value is.
Through our advisory services, we help Rochester and Monroe County households look at realized gains, available losses, and their overall income picture together, so year-end trades are made with the full context rather than in isolation.
That coordination between what your investment accounts are doing and what your return will look like is usually where the real savings appear.
The Bottom Line
Losses in a taxable account are an asset if you use them.
Offset your gains, take the ordinary income deduction if you have excess losses, carry the rest forward, and respect the wash sale rule so the effort is not wasted.
Just make sure the investment decision makes sense on its own. The tax benefit should be the bonus, not the reason.
