For much of your working life, managing a taxable investment account can be relatively hands-off. You invest consistently and give your portfolio time to grow. But once you retire and begin relying on your investments for income, you’ll face more decisions about which investments to sell and when to sell them. Those choices can have a significant impact on your tax bill.
Managing capital gains may seem like another complicated part of retirement planning, but the basic principle is fairly simple: timing matters. Being intentional about when you realize gains can help you manage the taxes you owe.
What capital gains actually are.
When you sell an investment for more than you paid for it, the difference is considered a capital gain. How a gain is taxed depends in part on how long you’ve owned the investment. Generally, investments held in a taxable account for more than one year receive long-term capital gains treatment, while investments held for less than one year are treated as short-term gains. This distinction matters because short and long-term gains can receive different tax treatment. Understanding what you own, what you paid for it, and how long you’ve held it gives you a starting point for making more thoughtful selling decisions.
Capital gains planning in retirement.
While you’re working, most of your income may come from a paycheck, and selling investments might be an occasional event. In retirement, your portfolio may become one of your primary sources of income, which means deciding what to sell can have a much more direct impact on your taxable income from year to year. Retirement income can also be less consistent than a paycheck. One year you may have relatively little taxable income, while another year could include larger retirement account withdrawals or investment gains. That variability creates some complexity, but it can also create planning opportunities.
Tax-loss harvesting.
No one likes seeing an investment decline in value, but a loss may have some value from a tax-planning perspective. Tax-loss harvesting involves selling an investment at a loss and using that loss to offset capital gains elsewhere in the portfolio. Depending on your situation, excess losses may also be used against a limited amount of ordinary income or carried forward to future tax years. The key is to make the sale decision as part of your larger investment strategy rather than simply because the market has fallen.
Tax-gain harvesting.
Sometimes realizing a gain intentionally can make sense too. Tax-gain harvesting involves selling appreciated investments during a year when your taxable income is relatively low. Depending on your income and filing status, some long-term capital gains may qualify for a lower federal tax rate. This can be especially relevant during certain retirement years. For example, you may have a period after leaving work when earned income has stopped but before other sources of taxable income increase. Those lower-income years can be worth identifying in advance rather than simply letting them pass by.
Why timing matters in retirement.
Capital gains don’t exist in a vacuum. Realizing a large gain can affect other parts of your financial picture, which is why it’s important to look beyond the tax on the investment itself.
Retirement account withdrawals can increase your taxable income. Required minimum distributions and other withdrawals from tax-deferred accounts affect your overall income for the year, which can influence how additional investment gains are taxed.
Capital gains can affect the taxation of Social Security benefits. Depending on your overall income, realizing additional gains could increase the portion of your Social Security benefits subject to federal income tax.
A higher-income year can affect Medicare premiums. Medicare uses income-related adjustments for certain premiums, so realizing a significant gain could potentially increase future Medicare costs.
None of these considerations should automatically preclude you from realizing a gain. They simply reinforce why it’s worth looking at the entire tax picture before making the decision.
Take a thoughtful approach.
Capital gains planning tends to work best when it’s proactive. Rather than waiting for a market move to force your hand, periodically review where your portfolio stands. Which investments have meaningful gains? Where do you have losses? What does your taxable income look like this year? Are there opportunities for adjustments while staying aligned with your investment strategy?
Before making investment sales, take a look at your gains, losses, and overall income for the year. A little planning around what you sell and when you sell it can help you manage the tax impact while keeping your decisions aligned with your broader retirement goals.
Frequently asked questions.
What is the difference between a short-term and long-term gain?
Generally, a gain is considered short-term if you held the investment for one year or less and long-term if you held it for more than one year. Long-term gains typically receive more favorable federal tax treatment than short-term gains.
Can capital losses reduce my taxes in retirement?
Capital losses can generally be used to offset capital gains, which may reduce your taxable income. If your losses exceed your gains, you may also be able to deduct a limited amount against ordinary income and carry additional losses forward to future years.
When might tax-gain harvesting make sense?
Tax-gain harvesting may be worth considering during years when your taxable income is lower than usual. Intentionally realizing gains during those years could allow you to take advantage of a lower long-term capital gains tax rate, depending on your individual situation.
Can capital gains affect my Social Security or Medicare costs?
Realizing capital gains may increase your income for certain tax calculations, potentially impacting how much of your Social Security is taxable or whether you pay income-related Medicare premium adjustments.
When should I review my portfolio for capital gains planning opportunities?
It can be helpful to review your gains and losses throughout the year and again as year-end approaches, when you may have a clearer picture of your overall income. Any tax-driven investment decision should also be considered in the context of your broader investment and retirement strategy.
