5 Year-End Tax Moves for High Earners Before December 31 For high earners, the difference between a planned tax year and an unplanned one is often decided in the final weeks of December. Many of the most useful moves have a hard deadline of December 31, and once the calendar turns, the option is gone. Here are five year-end tax moves for high earners to consider before the deadline, each with the limits that decide whether it actually fits your situation. A caution first: none of these is universally right. Each depends on your income, your accounts, and your goals, and some can backfire if applied carelessly. This is general information, not advice for your facts. 1. Max Out Tax-Advantaged Retirement Contributions Contributing fully to available retirement accounts can reduce taxable income, and some accounts have year-end or filing-deadline timing. The limit: contribution caps and eligibility phase-outs apply, and the right account mix depends on your situation. Still, leaving room on the table is a common, avoidable miss. 2. Harvest Investment Losses Selling investments at a loss can offset capital gains and, to a limited extent, ordinary income. The limit: wash-sale rules restrict repurchasing the same security too quickly, and harvesting should serve your overall strategy, not just the tax. Done thoughtfully with your advisor, it can meaningfully reduce a tax bill in a year with gains. 3. Time Charitable Giving Bunching charitable contributions into one year, or using a donor-advised fund, can increase the value of itemized deductions. The limit: the benefit depends on whether you itemize and on deduction rules, so it is not automatic. For high earners with charitable intent, the timing can matter as much as the amount. 4. Consider a Roth Conversion Converting traditional retirement funds to a Roth in a lower-income year can be powerful, paying tax now to avoid more later. The limit: it raises this year's taxable income and only makes sense under specific circumstances, so it is very much a plan-with-a-professional move. The window is the calendar year, which is why December matters. 5. Review Estimated Taxes and Withholding High earners often underpay through the year and face penalties. A year-end check of estimated payments and withholding can avoid a surprise. The limit: this is about avoiding penalties, not reducing the tax itself, but it is a cheap, high-value review before the year closes. Why Proactive Planning Beats April Filing The theme is timing. By April, these moves are off the table; they had to happen by December 31. That is the...
