Why Year-End Planning Matters
Tax planning is most effective before December 31, when you still have time to take action. Waiting until tax filing season means reporting what happened — not optimizing the outcome. Even simple moves like maximizing retirement contributions or harvesting investment losses can save thousands annually. The effort-to-reward ratio of year-end tax planning is among the highest in personal finance.
Maximize Tax-Advantaged Contributions
Ensure you're maximizing available tax-advantaged accounts before year-end:
• 401(k): $23,500 limit ($31,000 if 50+) — increase your contribution rate for remaining paychecks • HSA: $4,150 individual / $8,300 family — contributions are above-the-line deductions • Traditional IRA: $7,000 ($8,000 if 50+) — deductible if you meet income requirements • 529 Plans: State-specific limits — may provide state tax deductions
Tax-Loss Harvesting
If you have investments with unrealized losses in taxable accounts, selling them before year-end lets you offset capital gains and up to $3,000 of ordinary income. After selling, wait 31 days (to avoid wash sale rules) and reinvest in a similar but not identical fund. This strategy lowers your current tax bill while maintaining your investment strategy.
Charitable Giving Strategies
Bunching charitable donations into a single year can push you above the standard deduction threshold, making donations tax-deductible. Donor-advised funds allow you to take the deduction now and distribute to charities over time. Donating appreciated stock directly avoids capital gains tax entirely while providing a full fair-market-value deduction.
Income Timing and Roth Conversions
If you expect lower income this year than next, consider converting Traditional IRA funds to Roth at the lower tax rate. Conversely, if you can defer income (year-end bonuses, freelance invoicing) to a year when you'll be in a lower bracket, the timing can save meaningful tax dollars. Always model the numbers before making these moves.
