From maximizing tax-advantaged savings accounts to donating to charity, here are strategic tax moves to consider before year-end.

Tax Day may still be months away, but there are plenty of actions you can consider taking before then to help manage your tax bill. In fact, certain tasks should not—or in some cases cannot—wait until next year, lest you miss out on potentially important tax opportunities.

Here are the top tasks to consider before December 31—and those you have until Tax Day on April 15, 2024, to accomplish.

To consider by year-end

Take required minimum distributions (RMDs)

If you’re age 73 or older, you generally must take minimum distributions from your tax-deferred retirement accounts by the end of the year. If you miss the deadline, you could be subject to a 25% penalty on the portion of your RMD you failed to withdraw.

Maximize your 401(k)

Contributing the maximum amount to your tax-deferred employer-sponsored retirement plan can help reduce your taxable income for the current year. In 2023, the maximum contribution for 401(k)s and similar plans is $22,500 ($30,000 if age 50 or older).

Contribute to a Roth 401(k)

If your employer offers the option and you haven’t maxed out your traditional 401(k), you can make after-tax contributions to a Roth 401(k) up to the $22,500 limit ($30,000 if age 50 or older)—minus whatever you might’ve contributed to your traditional 401(k)—before year-end.

Consider a Roth conversion

If your income exceeds Roth individual retirement account (IRA) contribution limits (see “To consider by Tax Day” below for more on Roth IRAs), you can convert the pretax savings in a traditional IRA to a Roth IRA in order to reap those tax-free withdrawals in retirement. As with any withdrawal from a tax-deferred account, the converted funds will be treated as income, so generally, you’ll want to convert just enough to remain within your current tax bracket to avoid a hefty tax bill. For example, if you’re single and will earn $175,000 this year, you fall into the 24% tax bracket, which ranges from $95,376 to $182,100 in 2023. That means you can convert up to $7,100 ($182,100 – $175,000) without being pushed into the next bracket.

Consider a mega backdoor Roth

If permitted by your workplace retirement plan, a so-called mega-backdoor Roth allows high-income earners to save in a Roth account while eschewing the income limits of a Roth IRA and the tax consequences of a regular Roth conversion. To take advantage of this strategy, you first max out your normal, pretax 401(k) contributions for the year, then contribute after-tax dollars up to the overall account limit of $66,000 in 2023 ($73,500 if 50 or older), after which you can convert those funds to a Roth IRA. You’ll want to roll over those funds as quickly as possible to avoid being taxed on any additional investment returns.

Optimize your giving

If charitable giving is part of your financial plan, act by year’s end to ensure your donation is as tax-efficient as possible:

Exercise nonqualified stock options (NSOs)

If your company issues NQSOs, which are taxed as ordinary income when exercised, waiting until the end of the year allows you to exercise just enough to stay within your tax bracket, thereby keeping your taxes lower than if you had exercised your options all at once.

Harvest losses

The end of the year is a great time to make sure your portfolio is still aligned with your goals. When rebalancing, you may be able to reduce your tax liability by offsetting any realized capital gains with your losses. To employ this strategy, tally up your gains, then cash out losing positions of equal value. If you have more losses than gains, you can offset up to $3,000 of ordinary income. If you do employ tax-loss harvesting, be sure not to buy the same or a similar security within 30 days to avoid the pitfalls of the wash-sale rule.

To consider by Tax Day

Maximize all other tax-deferred savings accounts

Money set aside in these tax-advantaged accounts can potentially help reduce taxable income, and with these, you’ll have until Tax Day to make contributions for the prior tax year. For 2023, the maximum contributions are:

Contribute to a Roth IRA

Roth IRA contributions are made with after-tax dollars, so they won’t help reduce your taxable income. However, once you reach retirement, all contributions and earnings can be withdrawn tax-free if you’ve held the account for five years and are age 59½ or older—and Roth IRAs aren’t subject to RMDs. Unfortunately, you can’t contribute to a Roth IRA if your income exceeds $153,000 ($228,000 for married couples), and the contribution limit is gradually phased out for those with income between $138,000 and $153,000 ($218,000 and $228,000 for couples).

A final idea

In 2023, you can give away up to $17,000 ($34,000 if married) per person to an unlimited number of people without eating into your lifetime estate- and gift-tax exemption. This won’t reduce your taxable income for the year, but it will allow you to strategically transfer wealth to your heirs tax-free.
