The magician’s trick works because you watch the wrong hand.
Congress passes a sweeping tax law. The headlines celebrate. Business owners feel relieved. And while everyone focuses on what the government just gave them, something else is quietly reaching into the other pocket. Tariffs. Supply chain costs. Margin compression that does not show up in a deduction table but absolutely shows up in your bank account.
That is where we are in May 2026. The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, delivered genuinely significant tax relief to small business owners across the country. I want to be clear about that. These are real benefits, not political window dressing. However, reading the law without reading the economic environment around it is like counting your winnings at the poker table without noticing the house rake.
Today I want to give you both hands. What the law actually changed, what it actually means in dollar terms, and why the planning opportunity inside all of this is bigger than most business owners realize.
What the OBBBA Actually Did for Small Business Owners
Let’s start with the good news, because there is plenty of it.
The most consequential change in the OBBBA, at least for business owners who invest in equipment, vehicles, and technology, is the permanent restoration of 100% bonus depreciation. Under the old rules set by the Tax Cuts and Jobs Act, bonus depreciation was phasing out fast. It had already dropped to 60% in 2024 and was heading toward zero by 2027. If you bought a piece of equipment in 2025 under those old rules, you could only deduct 40% of the cost in year one.
The OBBBA reversed that entirely. For any qualified property acquired and placed in service after January 19, 2025, you can now immediately deduct 100% of the cost in the year you place it in service. That applies to both new and used assets, provided the asset is new to you and acquired at arm’s length. Equipment, computers, vehicles, furniture, certain interior improvements to commercial space… the list is broad.
For a business owner buying $150,000 in equipment, the difference between 40% and 100% first-year deduction is $90,000 in additional taxable income reduction. At a 32% bracket, that is roughly $28,800 in federal tax savings in a single year. That is not nothing. That is a real number that changes cash flow planning.
Section 179 Got Even Better
Beyond bonus depreciation, Section 179 also received a major upgrade.
For 2026, the Section 179 expensing limit is $2.56 million, with a phase-out beginning at $4.09 million of total qualifying property placed in service. The deduction phases out completely once you hit $6.65 million. These limits are inflation-adjusted going forward, so they will not erode in real terms over time.
For context, the pre-OBBBA limit was $1.25 million with a phase-out starting at $3.13 million. The new law more than doubled the cap. For mid-sized businesses investing heavily in capital equipment, this expansion meaningfully changes the math.
The strategic difference between bonus depreciation and Section 179 is worth understanding. Bonus depreciation applies automatically to entire asset classes and can create a net operating loss, which then carries forward to offset future income. Section 179 cannot create a loss but gives you asset-by-asset control, which is useful when you want to fine-tune your taxable income to a specific number.
In most situations, the right approach is to apply Section 179 first where precision matters, then layer bonus depreciation on top for everything else. A conversation with your tax advisor about this sequence could easily be worth thousands of dollars in a single year.
The QBI Deduction Is Now Permanent
The other headline change from the OBBBA is the permanent extension of the Section 199A Qualified Business Income (QBI) deduction. This one matters enormously for sole proprietors, partnerships, and S-corporation owners.
Before the OBBBA, the QBI deduction was always scheduled to sunset at the end of 2025. Business owners who structure around this benefit, including those who have made S-corporation elections specifically to optimize the QBI calculation, have been living with that uncertainty since 2017. That uncertainty is now gone.
The deduction allows eligible pass-through business owners to deduct up to 20% of their qualified business income. For 2026, the full deduction is available for single filers with taxable income below approximately $203,000 and married filing jointly filers below approximately $406,000. Above those thresholds, limitations based on W-2 wages paid and qualified property may reduce or phase out the deduction, particularly for owners of specified service trades or businesses (SSTBs) such as consulting, law, and financial services.
Two additional improvements deserve mention. First, the OBBBA widened the phase-in ranges. Previously, a single filer had a $50,000 phase-in window above the threshold before the deduction was fully eliminated. That window is now $75,000. For married couples, it expanded from $100,000 to $150,000. More business owners at higher income levels now qualify for at least a partial deduction.
Second, the law introduced a new minimum deduction of $400 for any active business owner with at least $1,000 in qualified business income. Even at the top of the income range, where the standard calculation might otherwise produce zero, there is now a floor.
The QBI deduction becoming permanent is not just a tax benefit. It is a planning foundation. You can now build compensation strategies, entity elections, and retirement contributions knowing the 20% deduction will be there in five, ten, and twenty years.
If you have been putting off an S-corporation conversion because of the QBI sunset risk, that reason no longer exists. The piece I wrote on LLC vs. S-Corp planning in 2026 covers the broader decision framework, and that math looks even better now that the QBI deduction is locked in.
Now the Other Hand
Here is where the picture gets more complicated, and more interesting.
At the same time Congress was delivering these benefits, the trade environment was doing something very different to the bottom lines of small business owners across South Florida.
The tariff story of 2025 and 2026 is not simple. The Trump administration imposed sweeping tariffs under emergency powers in 2025. The Supreme Court ruled those IEEPA-based tariffs unconstitutional in February 2026. The administration immediately pivoted to Section 122 authority, imposing a 10% global tariff with a 150-day clock. Sector-specific tariffs on aluminum, copper, steel, and pharmaceuticals remain in place under separate authority. At the same time, targeted Section 301 investigations are underway against dozens of countries, with the possibility of new country-specific tariffs to follow.
The result is an environment that has not returned to stability. It has simply changed its legal wrapper.
For small business owners, the numbers are real. Research from the American Action Forum estimates that direct tariff costs to U.S. small businesses run approximately $85 billion annually. Small businesses are structurally more vulnerable than large ones, because they typically rely on fewer suppliers, import from fewer countries, and have less leverage to renegotiate contracts or absorb margin hits.
A report from the Federal Reserve Bank of Atlanta found that small businesses expected sales to be nearly 9% lower compared to normal levels, while large firms expected a 3.5% dip. That is a gap that matters.
Why South Florida Business Owners Feel This Differently
Weston sits in a region that has a very specific relationship with international trade. South Florida is a gateway economy. Construction, retail, hospitality, import-driven distribution, and professional services all have supply chains that run through ports, through Latin America, through European suppliers. When tariff costs move, they move through those channels quickly.
Think about what has happened to construction materials over the past 18 months. Aluminum tariffs at 25% to 50% on full customs value. Steel derivatives subject to additional levies. A contractor or developer in Broward County who priced a project last year and is executing it this year is looking at cost structures that did not exist when they signed the contract. That is a margin compression problem that no depreciation deduction fully offsets.
Furthermore, service businesses that depend on imported technology, equipment, or even software infrastructure face indirect cost pressure. And businesses that export, or that serve clients who do, face the added complexity of retaliatory measures in foreign markets.
The Planning Opportunity That Lives in the Gap
Here is what I find genuinely exciting about this moment, and I mean that without any sarcasm.
The gap between what the tax law gives and what the economic environment takes creates a planning problem that is more nuanced than either side of the equation on its own. And more nuanced problems reward more sophisticated planning.
Consider a business owner in Weston who invests $200,000 in new equipment this year. Under the OBBBA, they can deduct the full $200,000 in year one via bonus depreciation. If they are in the 32% bracket, that is approximately $64,000 in federal tax savings. Meanwhile, their material costs are running 10% to 15% higher because of tariff-driven price increases on their inputs. If their cost base runs $500,000 per year, that tariff impact could be $50,000 to $75,000 in additional expense.
The tax savings and the cost increase are both real. However, they are not on the same clock. The depreciation deduction happens this year on this year’s return. The cost pressure is ongoing, year after year, until trade policy stabilizes. That asymmetry matters enormously for cash flow planning and for how you time major capital investments.
If you are going to buy equipment anyway, buying it now is almost certainly the right call, because the full 100% deduction is available and the timing advantage is real. If you are considering a major purchase primarily as a tax move, the analysis needs to account for how tariff pressure on your operating costs affects whether you actually need the asset and whether the cash flow timing works.
This is also a strong argument for the kind of proactive mid-year planning I described in the Tax Planning Starts Now piece from earlier this year. The business owners who use this moment well are not waiting until December. They are modeling both the tax benefits and the cost environment together, right now, while there is still room to adjust.
The Entity Structure Question Becomes Even More Urgent
One more layer worth examining: the combination of permanent QBI and a challenging cost environment makes your entity structure more consequential than ever.
If you are operating as a sole proprietor or a single-member LLC taxed as a disregarded entity, you may be leaving significant QBI deduction money on the table. The S-Corp reasonable salary question that I have written about before becomes even more important when the deduction is permanent, because optimizing the salary-versus-distribution split in an S-Corp can dramatically affect how much of your income qualifies for the 20% deduction.
At the same time, if your cost pressures are rising and margins are tightening, the structure of your entity affects how much flexibility you have in managing cash. An S-Corp election requires payroll compliance, reasonable compensation calculations, and more administrative overhead. For some businesses in the current environment, that overhead is absolutely worth it. For others, the math is less clear. Every situation is different, and as I have said before, your neighbor’s answer is probably not your answer.
What I Would Be Doing Right Now
The simplest version of the right response to this moment is this: capture the benefits that are available to you now, and plan for the costs that are coming.
On the benefit side, that means reviewing any major capital purchases you have been considering and understanding exactly how bonus depreciation and Section 179 interact for your specific entity type and income level. It means stress-testing your QBI calculation under the new permanent rules and making sure your compensation structure still makes sense. It also means confirming that your entity type is still the right one, because the law changed enough in 2025 to make many prior decisions worth revisiting.
On the cost side, it means looking honestly at your supply chain and identifying where tariff exposure sits. It means pricing that exposure into your forward projections, not just looking backward at last year’s numbers. And it means understanding that the tax savings and the cost pressures live in the same business and need to be managed together.
Because a $64,000 deduction benefit and a $60,000 cost increase in the same year are not a wash. They are two different planning variables, and they require two different responses. One is a reason to act strategically. The other is a reason to be cautious. Holding both truths at the same time is what separates reactive tax filing from genuine tax strategy.
The law changed everything. Just not the way most people think.
