What are the biggest changes for 2026 tax planning?
The One Big Beautiful Bill Act created four major opportunities for tax savings in 2026. The most impactful change is the enhanced retirement contribution limits — 401(k) limits increased to $23,500 (up from $20,000 in 2023) with a new "super catch-up" provision allowing $34,750 for ages 60-63.
The second major change is expanded Section 179 deduction limits for business equipment, now capped at $1.2 million (up from $1.08 million). Third, the simplified home office deduction now allows $7 per square foot up to 400 square feet ($2,800 maximum). Finally, charitable deduction limits increased from 60% to 65% of AGI.

What you should do before December 31, 2026
1. Increase your 401(k) contribution to capture the higher limits — even an extra $100/month saves $264-$370 in taxes
2. Review your withholding using the IRS Tax Withholding Estimator with updated 2026 brackets
3. Accelerate equipment purchases if you're self-employed to capture bonus depreciation
4. Consider Roth conversions while tax rates remain historically favorable
5. Bundle charitable contributions if you're close to the itemizing threshold
Key takeaway: The 2026 tax changes create $800-2,400 in additional annual tax savings for most middle-income taxpayers through enhanced retirement limits and expanded deductions, but only if you adjust your strategy before year-end.

High-earner considerations for 2026 tax changes
For high earners, the 2026 tax law changes create both opportunities and new limitations. The Net Investment Income Tax (NIIT) threshold remained at $200,000 (single) and $250,000 (married), but the additional Medicare tax now applies to wages over $250,000 (up from $200,000 for singles).
Estate planning implications are significant — the federal estate tax exemption increased to $13.99 million per person for 2026, but this enhanced exemption is set to sunset in 2027 unless extended.
Strategic considerations for $200,000+ earners
Retirement planning becomes more complex:
Investment and business income:
Multi-state tax planning:
Key takeaway: High earners face more complex planning with phase-outs and limitations, requiring careful timing of income recognition and sophisticated retirement strategies to maximize the enhanced contribution limits.
Key Takeaway: High earners need sophisticated strategies around income timing, retirement maximization, and multi-state planning to optimize the 2026 changes while managing phase-outs and limitations.
