Imagine waking up on January 1, 2026, and discovering that your hard-earned income is suddenly subject to a tax rate nearly 10% higher than the year before—not because you earned more, but because the law simply "reset." According to the Congressional Budget Office (CBO), the expiration of the Tax Cuts and Jobs Act (TCJA) is projected to increase federal revenues by $4.6 trillion over the next decade as individual tax provisions sunset. For high earners, self-employed professionals, and US expats, this isn't just a political talking point; it is a ticking clock. At Zenith Financial Advisors, we are already seeing a surge in "bracket anxiety" among our clients. The jump from 37% back to the 39.6% top tax bracket, combined with the loss of the 20% Qualified Business Income (QBI) deduction, represents a massive shift in how you must manage your taxable income. In this guide, our team outlines the precise legal methods to insulate your wealth before the 2026 deadline.
Key Takeaways for 2026 Planning
- Income Shifting: Accelerate bonuses and capital gains into 2025 to lock in the 37% rate.
- QBI Expiration: The 20% deduction for self-employed individuals (Section 199A) disappears after Dec 31, 2025.
- Exemption Cliff: The lifetime gift/estate tax exemption is expected to drop from approximately $13.61 million to roughly $7 million.
- Expat Arbitrage: Strategically using Form 1116 (Foreign Tax Credit) to bank credits before US rates climb.
1. Income Shifting: The Art of Bracketing Early
The most fundamental rule of tax planning is to pay taxes when the rates are lowest. As we approach the TCJA sunset, we are advising our clients to front-load their taxable income into the 2024 and 2025 tax years. If you are a business owner or a professional with control over your billing cycles, this may mean incentivizing clients to pay outstanding invoices before year-end 2025 or taking a larger distribution from your S-Corp earlier than originally planned.
For 2024, the top tax bracket of 37% applies to single filers with income over $609,350 and married couples filing jointly with over $693,750. Per the Tax Foundation, when these rates revert in 2026, the 39.6% bracket will likely kick in at much lower thresholds—estimated at approximately $450,000 for individuals, adjusted for inflation. By realizing income now, you are essentially buying a "discount" on your tax bill compared to what you will owe in 2026.

Income shifting isn't just for business owners. If you have non-qualified deferred compensation plans or significant stock options (ISOs or NSOs), 2025 might be the optimal window to exercise and sell. Our team uses multi-year projections to ensure that by accelerating income, you don't inadvertently push yourself into a situation where the Alternative Minimum Tax (AMT) negates your savings. Planning requires a surgical approach to Form 1040 Schedule D and Schedule C reporting.
2. Protecting the 20% QBI Deduction (Section 199A)
For our self-employed clients and small business owners, the loss of the Section 199A deduction is perhaps the most significant "hidden" tax hike. Currently, eligible taxpayers can deduct up to 20% of their qualified business income from their taxable total. According to the IRS, over 17 million taxpayers benefited from the QBI deduction in recent filing cycles. However, this provision is scheduled to expire entirely on December 31, 2025.

To maximize this before it's gone, we recommend looking at capital expenditures. Under Section 179 and Bonus Depreciation (which is also phasing down—currently 60% in 2024, 40% in 2025, and 20% in 2026), you can reduce your 2024/2025 taxable income while still qualifying for the 20% QBI haircut. After 2025, that 20% "free" deduction disappears, meaning a business owner earning $500,000 could see their taxable base increase by $100,000 overnight.

3. Strategic Roth Conversions: Pay Now, Save Later
If you believe your tax rate will be higher in 2026 and beyond (which it legally will be, barring new legislation), a Roth conversion in 2024 or 2025 is a powerful move. By converting a Traditional IRA or 401(k) to a Roth IRA now, you pay taxes at the current 37% (or lower) rate. Once the funds are in the Roth, they grow tax-free, and future withdrawals are also tax-free.
Per IRS Notice 2024-02, the rules around retirement contributions and distributions continue to evolve with SECURE 2.0, but the core benefit of the Roth remains: tax-rate arbitrage. If you wait until 2026 to realize that income through a conversion, you may be paying that 39.6% premium. We work with clients to "fill up" their current tax brackets—converting just enough to stay within the 32% or 35% bands before they jump higher in 2026.
PRO TIP: The "Bracket Topping" Strategy
Most taxpayers wait until April to think about their brackets. Instead, look at your projected 2024 income today. If you are $50,000 away from the next highest bracket, consider a Roth conversion or a capital gain harvest for exactly that amount. You are effectively "locking in" current low rates on money that would otherwise be taxed at 39.6% in the future.
4. Cross-Border Optimization: Credits vs. Exclusions
For our US expats living in Canada or abroad, the 2026 shift adds a layer of complexity to Form 2555 (Foreign Earnings Income Exclusion) versus Form 1116 (Foreign Tax Credit). Currently, many expats use the Foreign Tax Credit (FTC) to offset US taxes because foreign rates (like those in Canada or the UK) are often higher than the US 37% top rate.
However, as the US top tax bracket 2026 rises to 39.6%, the "buffer" of foreign credits may shrink. According to FinCEN data, over 1.2 million FBARs (Report of Foreign Bank and Financial Accounts) are filed annually, highlighting the massive scale of Americans living abroad who must navigate these shifts. If the US rate exceeds your local foreign rate, you could owe a residual US tax for the first time in years. At Zenith, we help clients "bank" excess foreign tax credits now, which can often be carried forward for up to 10 years, to offset the higher US bills coming in 2026.
5. The Gift Tax Exemption Sunset: Use It or Lose It
Perhaps the most urgent deadline involves the unified gift and estate tax exemption. In 2024, an individual can transfer $13.61 million (or $27.22 million for a married couple) tax-free. On January 1, 2026, this exemption is scheduled to revert to the pre-TCJA level of roughly $5 million, adjusted for inflation—likely around $7 million.
The IRS issued Treasury Decision 9884, confirming that taxpayers who take advantage of the higher gift tax exclusion before 2026 will not be "clawed back" when the exemption drops. This means if you have a high net worth, gifting assets into an Irrevocable Life Insurance Trust (ILIT) or a Spousal Lifetime Access Trust (SLAT) in 2025 could save your heirs millions in 40% estate taxes. This is the ultimate form of income shifting—shifting the future appreciation of assets out of your taxable estate entirely.
Common Mistakes to Avoid
- Ignoring the SALT Cap Expiration: While the $10,000 State and Local Tax (SALT) cap is scheduled to expire (a potential win for those in high-tax states like NY or CA), it may be replaced by new limitations. Don't assume your itemized deductions will be fully restored without watching the legislative updates.
- Over-Accelerating into the AMT: Moving too much income into 2025 can trigger the Alternative Minimum Tax. While the TCJA increased AMT exemption thresholds, these are also subject to revision and sunset nuances.
- Failing to Coordinate Cross-Border Credits: For US-Canada filers, failing to align the timing of Canadian tax payments with US tax filings can lead to double taxation. Ensure your Form 1116 is filed on an accrual basis if appropriate.
- Missing the FBAR/Form 8938 Thresholds: As assets grow through 2026 planning, ensure you remain compliant with the $10,000 FBAR threshold (FinCEN Form 114) and the much higher Form 8938 thresholds for foreign financial assets.
Frequently Asked Questions
Will Congress extend the TCJA before 2026?
While there is political pressure to extend certain provisions (like the lower middle-class brackets), the top 39.6% rate is a frequent target for revenue generation. Relying on an extension is a high-risk strategy compared to proactive planning.
What happens to the Standard Deduction in 2026?
The Standard Deduction is set to decrease significantly (nearly halving). This means many taxpayers who currently take the standard deduction will find it more beneficial to itemize again, especially if the $10,000 SALT cap is lifted.
Does the 2026 sunset affect capital gains rates?
The 0%, 15%, and 20% long-term capital gains brackets are generally not part of the sunset, but the income thresholds for those brackets are tied to the ordinary income brackets, meaning more of your gains could potentially be pushed into the 20% tier.
Is the $10,000 SALT cap definitely going away?
Legally, yes, on Dec 31, 2025. However, this is one of the most debated pieces of tax law. We recommend planning for both scenarios: one where the cap remains and one where it is removed.
