3 Tax Planning Opportunities Before December 31

With 2025 coming to an end, now is an opportune time for investors to evaluate decisions that may affect their tax obligations and overall financial well-being. Although financial planning should occur throughout the year, numerous tax-related deadlines align with December 31. Therefore, the closing weeks of the year present a valuable window for investors to assess their tax approaches and complete any actions that could influence their 2025 tax liability.

This article examines three important considerations for investors: retirement account distribution management, Roth IRA conversions, and tax-efficient portfolio positioning. Given the complexity of these topics and the varied rules affecting different people, consulting with professional advisors is essential.

December 31 deadline applies to Required Minimum Distributions

While much of the investment journey centers on accumulating wealth and building portfolios, the method of withdrawing from retirement savings carries equal importance. This becomes particularly critical when investors reach the age at which Required Minimum Distributions (RMDs) commence. December 31 stands as a crucial deadline in this context, as failing to meet it can trigger substantial IRS penalties—currently 25% of the amount that should have been withdrawn.

RMDs represent mandatory annual withdrawals from traditional IRAs, 401(k)s, and similar tax-deferred retirement vehicles once account holders reach a specified age. The SECURE 2.0 Act, enacted by Congress in 2022, increased the RMD starting age to 73 for individuals who turned 72 after December 31, 2022. This threshold will rise again to 75 in 2033.

The accompanying chart displays current distribution periods measured in years, along with corresponding required withdrawal percentages applicable to most account holders. Withdrawal amounts depend on the account balance from the previous year's December 31, modified by an IRS-published life expectancy factor. Despite straightforward calculations, the planning implications can prove considerably more intricate:

• Account selection: Thoughtful coordination helps determine which accounts to tap first, optimal withdrawal timing during the year, and how to synchronize RMDs with additional income streams. The sequence of account withdrawals can impact total tax liability, particularly since Social Security benefits become taxable at specific income levels and may result in higher taxation.
• First-year delay: New RMD participants can postpone their initial distribution until April 1 of the subsequent year. However, this approach requires taking two RMDs in year two, potentially elevating the investor into a higher tax bracket.
• Other distribution strategies: Additional approaches include Qualified Charitable Distributions (QCDs), which enable investors to contribute directly from their IRA to eligible charities. This satisfies the RMD obligation while avoiding an increase to taxable income. Nevertheless, timing considerations surrounding these choices demand thorough planning.

Prior to reaching age 73, investors should evaluate whether voluntary distributions make sense. Some may benefit from withdrawing amounts that maximize their current tax bracket without crossing into the next higher bracket. This approach proves especially beneficial when higher tax brackets are expected once RMDs commence.

These considerations underscore why retirement planning demands a multi-year outlook rather than single-year focus.

Today's environment presents strategic advantages for Roth conversions

Roth conversions represent another valuable year-end planning mechanism with a December 31 deadline. Similar to RMDs, they demand thorough evaluation and preparation. A Roth conversion entails moving assets from a traditional IRA into a Roth IRA, generating immediate taxable income while securing tax-free growth and future withdrawals.

While Roth contributions face income restrictions, conversions remain accessible to all investors without income limitations. For high-income individuals exceeding Roth IRA contribution thresholds, these transactions are frequently termed "backdoor" Roth conversions.

The "One Big Beautiful Bill" enacted earlier this year permanently extends the reduced tax rates established under the Tax Cuts and Jobs Act. Many investors currently face more advantageous tax rates compared to potential future scenarios. Given mounting national debt and ongoing fiscal deficits, concerns about future tax rate increases add another dimension to conversion decisions.

Important factors influencing Roth conversion decisions include:

• Tax bracket comparison: Evaluating current versus expected retirement tax brackets guides conversion timing. Anticipating higher future brackets due to RMDs, pension distributions, or Social Security income suggests converting now at lower rates may prove beneficial
• Time horizon for tax-free growth: Extended periods of tax-free growth within the Roth account enhance conversion value. Therefore, earlier conversions often yield better results.
• Medicare premiums: Increased income from Roth conversions may activate Income-Related Monthly Adjustment Amounts (IRMAA), raising Medicare Part B and Part D premiums. While this doesn't necessarily preclude conversions, it represents another element in the comprehensive analysis.

Tax-loss harvesting provides opportunities to reduce tax liability and offset gains

Unlike RMDs and Roth conversions targeting retirement accounts, tax-loss harvesting applies to taxable investment portfolios and can optimize annual tax outcomes. This technique involves selling depreciated investments to recognize capital losses, which then offset capital gains recognized during the year. This must also occur before December 31 to affect the current tax year, making it an essential component of comprehensive investment and financial planning.

How does this function practically? When an investor sells investments during 2025 and recognizes capital gains, harvesting losses from other holdings can offset those gains on a dollar-for-dollar basis. Tax loss harvesting remains beneficial even during years without substantial gains. When losses surpass gains, investors can apply up to $3,000 of net capital losses against ordinary income each year, carrying forward any remaining losses to subsequent years.

Multiple factors influence tax-loss harvesting effectiveness:

• Capital gains rates: Long-term capital gains (from holdings exceeding one year) receive preferential tax treatment at 0%, 15%, or 20% rates based on income, whereas short-term gains face ordinary income tax rates. Harvesting losses to offset short-term gains can deliver exceptional value since those gains would otherwise incur higher taxation. This advantage may be amplified for residents of high-tax states.
• Wash sale rule: A critical consideration involves the "wash sale" rule, which prevents repurchasing identical or "substantially identical" securities within 30 days before or after the sale. This restriction stops investors from claiming tax losses while preserving identical investment positions. Investors may, however, substitute similar investments like an ETF, maintaining market exposure and desired asset allocation while still capturing the tax loss.
• Account considerations: Tax-loss harvesting applies exclusively to taxable brokerage accounts, not IRAs or 401(k)s where gains and losses don't trigger taxable events. This distinction exists because retirement accounts provide tax-deferred growth independent of internal trading activity.

Effective coordination of these strategies demands thorough planning

The effectiveness of year-end financial planning stems not merely from executing isolated strategies, but from coordinating them strategically to optimize overall benefits. Naturally, maintaining perspective on broader objectives remains crucial. While minimizing current-year taxes holds value, it shouldn't undermine overarching financial goals. Optimal planning weighs both near-term tax consequences and long-term wealth building, ensuring current decisions align with future aspirations.

The bottom line? Many investors can benefit from timely year-end actions. This is an ideal moment to examine your tax position and financial circumstances.
