Why 2025 Tax Planning Matters More Than Usual
The 2025 tax year brings several important inflection points. Key provisions of the Tax Cuts and Jobs Act (TCJA) are set to sunset after 2025, which means 2026 could look very different — higher rates, lower standard deductions, and the return of personal exemptions.
This makes proactive 2025 planning especially valuable. Here are the most impactful strategies to consider before December 31, 2025.
1. Maximize Retirement Contributions
401(k) and 403(b)
The 2025 employee contribution limit is $23,500 ($31,000 if age 50+). If you haven’t maximized your contributions, increasing your paycheck deferrals now can meaningfully reduce your taxable income.
New for 2025 — Super Catch-Up Contributions: Under SECURE 2.0, individuals ages 60–63 can make a “super catch-up” contribution of $11,250 (total $34,750) to employer plans in 2025. If you’re in this age range, this is a significant opportunity.
SEP-IRA (Self-Employed)
For self-employed individuals, the SEP-IRA limit is 25% of net self-employment income, up to $70,000 for 2025. Contributions can be made up to your tax filing deadline (including extensions).
Solo 401(k)
If you’re self-employed with no employees, a Solo 401(k) allows both employee deferrals ($23,500) and employer contributions (up to 25% of compensation), for a potential combined contribution of up to $70,000.
2. Roth Conversion Strategy
If 2025 is a lower-income year for you — perhaps due to a job transition, business startup losses, or retirement — consider converting traditional IRA funds to a Roth IRA.
Why it matters: Converting in 2025 means paying tax at current rates before potential TCJA sunset in 2026. If marginal rates increase in 2026, converting now locks in the lower rate.
Key considerations:
- The converted amount is added to your taxable income — model the impact carefully
- Avoid pushing income into a higher bracket or triggering Medicare IRMAA surcharges
- There’s no income limit for Roth conversions (unlike direct Roth IRA contributions)
3. Harvest Tax Losses
If you have investment accounts with unrealized losses, December is the time to harvest them. Tax-loss harvesting lets you:
- Offset capital gains dollar-for-dollar
- Deduct up to $3,000 of net losses against ordinary income per year
- Carry forward excess losses to future years
Watch for the wash-sale rule: You cannot repurchase substantially identical securities within 30 days before or after selling at a loss. You can immediately reinvest in similar (but not identical) funds to maintain your market exposure.
4. Qualified Business Income (QBI) Deduction — Last Major Year
The Section 199A QBI deduction allows eligible self-employed individuals and pass-through business owners to deduct up to 20% of qualified business income.
This deduction is currently scheduled to expire after 2025 unless Congress acts.
If you’re a business owner on the cusp of income limits:
- 2025 phase-out begins at $197,300 (single) / $394,600 (married filing jointly)
- Strategic timing of income and deductions can keep you in the deduction window
- Consider accelerating deductible expenses into 2025
5. SALT Deduction Strategy
The current $10,000 cap on state and local tax (SALT) deductions is one of the most impactful TCJA changes for high-income earners in high-tax states like Virginia, Maryland, and DC.
Pass-Through Entity (PTE) Tax Elections
Many states have enacted workarounds allowing pass-through businesses (S-Corps, partnerships) to pay state tax at the entity level — bypassing the individual SALT cap. Virginia, Maryland, and DC all have PTE elections.
If you own a pass-through business in these states, this election can restore thousands of dollars in federal deductions that the SALT cap currently blocks.
6. Accelerate Deductions, Defer Income
A classic year-end strategy is to accelerate deductible expenses into the current year while deferring income to the next:
Deductions to accelerate:
- Charitable contributions (including QCDs from IRAs if 70½+)
- Property tax prepayments (if local assessor allows)
- Business expenses and equipment purchases
- Professional fees and subscriptions
Income to defer (if possible):
- Year-end bonuses (negotiate to receive in January)
- Self-employment invoice timing
- Installment sale structuring
7. Year-End Charitable Giving Strategies
Qualified Charitable Distributions (QCDs)
If you’re 70½ or older and have a traditional IRA, you can donate directly to charity from your IRA — up to $108,000 in 2025 — through a QCD. This:
- Satisfies your Required Minimum Distribution (if applicable)
- Excludes the amount from your adjusted gross income entirely
- Provides a tax benefit even if you take the standard deduction
Donor-Advised Funds
If you’re planning a large charitable gift, consider bunching multiple years’ worth of contributions into a donor-advised fund in a single year. This can push you over the standard deduction threshold, allowing you to itemize — while spreading your actual donations to charities over multiple years.
8. Review Your Withholding and Estimated Taxes
Before year-end, check whether you’ll owe a penalty for underpayment of estimated taxes. The IRS safe harbor requires you to pay either:
- 100% of last year’s tax liability (110% if AGI exceeded $150,000), OR
- 90% of your current year’s tax liability
If you’re short, making an additional estimated payment by January 15, 2026 (for Q4 2025) can reduce or eliminate the penalty.
Planning for 2026 — TCJA Sunset Watch
Assuming no congressional action, key TCJA provisions expiring after 2025 include:
- Higher individual tax rates returning (top rate goes from 37% to 39.6%)
- Standard deduction cut roughly in half
- Personal exemptions returning ($5,300+ per person estimated)
- Child Tax Credit reducing from $2,000 to $1,000
- QBI deduction eliminated
This potential change argues for accelerating income into 2025 (locking in lower rates) and deferring deductions to 2026 (when itemizing may become more valuable again) — the opposite of the usual advice.
