Year-End Tax Planning Strategies for 2026

By the time you prepare your tax return, many decisions affecting what you owe have already been made. Year-end planning gives you a chance to review those decisions while there is still time to act.

Whether you are managing investments, receiving equity compensation, or preparing for retirement, your financial choices rarely happen in isolation. Selling stock can affect your income. A Roth conversion can change the tax impact of other decisions. Charitable giving may work differently depending on what you donate and how you make the gift.

Before 2026 ends, take time to coordinate your investment, retirement, charitable, and income decisions. The goal is not simply a smaller tax bill. It is a more thoughtful connection between your taxes and the financial goals you are working toward.

Key Takeaways

• Review investment gains and losses together before selling investments or rebalancing.
• Confirm retirement contribution opportunities, Roth conversion considerations, and required distribution deadlines.
• Evaluate charitable gifts under the rules applicable to 2026, including new deduction provisions.
• Compare withholding and estimated payments with your projected tax liability, especially after bonuses or equity transactions.
• Start early enough to accommodate payroll, account custodian, and charitable transfer processing deadlines.

Why Year-End Tax Planning Matters

Some planning opportunities remain available until the tax filing deadline. Others depend on transactions occurring within the calendar year. For example, investment sales affect the year in which gains and losses are realized, while most annual required minimum distributions must be taken by December 31. Eligible IRA contributions generally have a later deadline¹.

That distinction matters. Discovering an opportunity in March does not necessarily mean you can apply it to the prior year.

Still, reducing this year’s taxes should not override your broader plan. Holding too much employer stock to avoid capital gains, making a charitable gift you cannot comfortably afford, or completing a large Roth conversion without evaluating its tax cost can create other problems.

A useful starting point is a projection of your 2026 income and taxes. Ask your CPA to incorporate investment activity, retirement distributions, compensation, and any planned transactions. Then evaluate potential changes with your financial advisor before taking action.

Year-End Tax Planning Strategies for 2026

A year-end review should bring together the decisions that are often considered separately: investment sales, retirement contributions, charitable gifts, income timing, deductions, and tax payments.

Begin by gathering your latest pay statement, investment gain-and-loss reports, retirement contribution totals, and records of estimated payments. Add expected bonuses, stock vesting, distributions, or other income that has not yet occurred.

Looking ahead is equally important. A planned retirement, business sale, or unusually high-income year in 2027 may influence whether a transaction makes more sense now or later. Where you have legitimate flexibility, ask your tax professional to compare the alternatives rather than assuming that deferring income or accelerating deductions is always better.

Investment and Portfolio Tax Strategies

Review Opportunities for Tax-Loss Harvesting

Tax-loss harvesting involves selling an investment at a loss in a taxable account. Realized capital losses can offset capital gains. If losses exceed gains, you can generally deduct up to $3,000 against other income, or $1,500 if married filing separately, and carry unused losses forward¹.

The tax benefit is only part of the decision. Consider whether selling the investment improves your portfolio and what you will hold instead.

Wash-sale rules generally disallow a loss deduction when you acquire substantially identical securities within 30 days before or after the loss sale. Purchases in an IRA or Roth IRA can also trigger these rules².

Before selling, review purchases across your accounts, including automatic investments and dividend reinvestments. A late-December loss sale can still be affected by a January purchase within the wash-sale window.

Review Capital Gains Before Year-End

Your unrealized gains show how much investments have appreciated. Your realized gains show what you have already recognized through sales. Both deserve attention, but they play different roles in tax planning.

Holding periods matter, too. Investments held for more than one year generally receive long-term capital gain treatment, while gains on investments held one year or less are generally taxed as ordinary income¹.

Download a year-to-date realized gain-and-loss report from each taxable account. Before making another sale, ask your advisor and CPA to evaluate the proposed transaction alongside existing gains, available losses, and your expected income.

Avoid letting taxes become the only reason to keep an investment. A tax cost may be acceptable when a sale addresses excessive concentration or supports an important financial need.

Rebalance With Taxes in Mind

A portfolio review may reveal that market changes have pushed your investments away from your intended allocation. Restoring that allocation can involve selling appreciated holdings, so the tax consequences deserve consideration.

Ask whether new contributions, available cash, or planned withdrawals can help adjust the allocation before making taxable sales. If sales are appropriate, review the specific tax lots rather than treating every share of an investment as having the same cost basis.

The objective is to coordinate tax efficiency with an appropriate portfolio, not preserve an unsuitable allocation simply to avoid realizing a gain.

Retirement and Income Tax Planning Strategies

Review Retirement Contributions

Check how much you have contributed so far and whether you have room to contribute more. For 2026, the employee contribution limit for most 401(k) and 403(b) plans is $24,500 before eligible catch-up contributions. The IRA contribution limit is $7,500, with an additional $1,100 available for those age 50 or older. Income and workplace coverage can affect IRA deductibility and Roth IRA eligibility³.

Contact your payroll team early about changes to remaining workplace contributions. Do not assume a last-minute election will reach the final paycheck.

IRA contributions generally can be made by the tax filing deadline, excluding extensions. That later deadline should not be confused with the timing of workplace payroll contributions or other year-end transactions⁴.

Also distinguish between tax treatments. Pre-tax contributions may reduce current taxable income, while Roth contributions do not provide a current deduction. Choose the approach based on your broader retirement and tax plan.

Evaluate Roth Conversion Opportunities

A Roth conversion moves eligible retirement assets into a Roth account and generally creates taxable income on amounts that have not previously been taxed. Conversions cannot later be reversed through recharacterization⁵.

A lower-income year may create an opportunity, but a conversion is not automatically beneficial. The amount converted, your current tax bracket, expected future income, and the funds available to pay the tax all matter.

Ask your CPA to compare several conversion amounts rather than evaluating an all-or-nothing decision. Include the conversion in your complete tax projection and confirm the custodian’s processing deadline if you want it reflected in 2026.

Review Required Minimum Distributions

If you are subject to required minimum distributions, or RMDs, confirm the amount required and how much you have already withdrawn.

For traditional IRA owners reaching age 73 in 2026, the first RMD generally can be delayed until April 1, 2027. However, the next annual RMD is still due by December 31, 2027, potentially placing two distributions in the same tax year. Most subsequent annual RMDs are due December 31. Workplace plan exceptions and inherited-account rules require separate review⁶.

Do not assume a withdrawal from one account satisfies every account’s requirement. Ask your advisor or custodian to confirm the applicable rules, then coordinate any remaining distributions with charitable plans and your projected income.

Charitable Giving Strategies Before Year-End

Start with what you want your giving to accomplish. Then consider which assets and giving methods fit both that purpose and your finances.

If you own appreciated securities held for more than one year, donating them directly to an eligible public charity may avoid the capital gains tax associated with selling them first. A charitable deduction may also be available, subject to applicable limits and requirements. A donor-advised fund can allow you to make a charitable contribution now and recommend grants over time, but the contribution is irrevocable⁷.

For eligible IRA owners age 70½ or older, a qualified charitable distribution, or QCD, transfers funds directly from an IRA to an eligible charity. A qualifying QCD can count toward an IRA RMD and is excluded from taxable income rather than claimed as a separate charitable deduction⁸.

The 2026 rules also deserve attention. Beginning this year, itemizers generally can deduct charitable contributions only to the extent they exceed 0.5% of adjusted gross income. Eligible non-itemizers may deduct up to $1,000, or $2,000 for joint filers, for qualifying cash contributions to certain organizations⁹.

Before transferring assets, ask your CPA how these provisions affect your gift. Confirm the recipient’s eligibility, documentation requirements, and processing timeline. If considering a QCD, verify that the recipient qualifies rather than assuming every charitable organization or giving vehicle is eligible.

Year-End Tax Planning for Executives and High-Income Earners

When your income includes bonuses, equity compensation, and investment proceeds, a salary-based estimate may miss important parts of your tax picture.

Build a calendar of expected compensation events and planned stock transactions. Include vesting dates, potential option exercises, sales, and any company trading restrictions. Your advisor and CPA can then evaluate the combined impact rather than reviewing each event separately.

Also compare taxes already paid with your projected liability. Withholding may not cover taxes associated with all your income, particularly capital gains or other income outside regular payroll. Depending on your circumstances, additional withholding or estimated payments may be appropriate.

If you hold a concentrated employer-stock position, consider diversification and charitable giving together. Any transaction should also be reviewed against company policies and applicable legal restrictions.

The practical next step is a coordinated conversation among your financial advisor, CPA, and, when needed, your company’s compliance team or legal advisor.

Your 2026 Year-End Tax Planning Checklist

Before year-end, work through these items:

• Investments: Gather realized gains, losses, and carryforwards. Review proposed sales and potential wash sales.
• Retirement contributions: Confirm remaining contribution room, eligibility, and payroll deadlines.
• Roth conversions: Compare potential conversion amounts and arrange for the associated tax payments.
• Required distributions: Verify RMD obligations and complete any remaining withdrawals on time.
• Charitable giving: Choose the assets and giving method, confirm 2026 deduction rules, and retain documentation.
• Income and deductions: Update your projection for bonuses, equity events, deductible expenses, and other relevant changes.
• Tax payments: Compare withholding and estimated payments with expected liability. The federal estimated payment for the final 2026 payment period is generally due January 15, 2027.
• Upcoming events: Discuss retirement, relocation, a business sale, or other changes that may affect next year’s plan.

Confirm federal and applicable state rules before acting. December 31 may be the legal deadline for a transaction, but your payroll provider, custodian, or charity may need instructions much earlier.

Conclusion

Year-end tax planning works best when your decisions support more than one year’s tax return. Investment sales, retirement contributions, charitable gifts, and income choices should fit the financial life you are building.
