The QBI Deduction (Section 199A): How South Florida Business Owners Can Save Up to $10,000/Year Before It Expires

The Qualified Business Income deduction lets pass-through business owners deduct up to 20% of their business income — but it sunsets after 2025. Here's exactly how to maximize it while you still can.

If you own a pass-through business in South Florida — whether you're an LLC, S-Corp, sole proprietor, or partner — there's a deduction available right now that could be saving you $5,000 to $10,000 or more per year. It's called the Qualified Business Income (QBI) deduction, codified in IRC Section 199A, and most business owners either don't know it exists or aren't maximizing it.

Worse: this deduction is scheduled to expire after the 2025 tax year unless Congress extends it. That means 2025 returns (filed in 2026) may be your last chance.

What Is the QBI Deduction?

The QBI deduction allows owners of pass-through businesses to deduct up to 20% of their qualified business income from their federal taxable income. It was created by the Tax Cuts and Jobs Act (TCJA) in 2017 and applies to tax years 2018 through 2025.

In plain English: if your business earns $200,000 in profit, you may be able to exclude $40,000 from your taxable income — without changing anything about how your business operates.

Who Qualifies in South Florida?

The QBI deduction is available to owners of pass-through entities, which includes most South Florida business structures:

Sole proprietors — freelancers, consultants, independent contractors
Single-member LLCs — the default for most Fort Lauderdale small businesses
S-Corporations — the preferred structure for high earners (see our S-Corp election guide)
Partnerships and multi-member LLCs

C-Corporations do not qualify — they have their own flat 21% rate.

The Math: How Much Can You Save?

Here's what the QBI deduction looks like for a typical South Florida professional:

Annual Business Income	QBI Deduction (20%)	Tax Savings (at 32% bracket)
$100,000	$20,000	$6,400
$150,000	$30,000	$9,600
$200,000	$40,000	$12,800
$300,000	Up to $60,000*	Up to $19,200*

*Subject to income phase-outs and W-2 wage limitations for higher earners — see below.

Combined with Florida's zero state income tax, this makes South Florida one of the most tax-efficient locations in the country for pass-through business owners.

The Income Limits You Need to Know

The QBI deduction has phase-out thresholds that affect higher earners. For the 2025 tax year:

Single filers under $191,950 — Full 20% deduction, no restrictions
Married filing jointly under $383,900 — Full 20% deduction, no restrictions
Above these thresholds — The deduction begins to phase out and becomes subject to the greater of:
- 50% of W-2 wages paid by the business, OR
- 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property

This is where entity structuring becomes critical. If you're a high-earning S-Corp owner in Fort Lauderdale paying yourself a reasonable salary, your W-2 wages directly increase your QBI deduction ceiling. This is one reason the S-Corp election and QBI deduction work so well together.

Specified Service Businesses (SSTB): The Exception

Certain professions are classified as "Specified Service Trades or Businesses" (SSTBs), which face additional restrictions at higher income levels:

Doctors, dentists, and healthcare professionals
Lawyers and accountants
Financial advisors and consultants
Athletes and performing artists

If you're an SSTB owner above the income threshold, your QBI deduction phases out entirely. However, many South Florida professionals in real estate, construction, engineering, architecture, and technology are not SSTBs — and can claim the full deduction regardless of income, as long as they meet the W-2 wage test.

Even SSTB owners below the threshold get the full 20%. A Fort Lauderdale attorney earning $180,000 still qualifies for a $36,000 deduction — saving roughly $11,500 in federal taxes.

How to Stack QBI With Other Strategies

The QBI deduction becomes even more powerful when combined with other IRS-backed strategies:

Strategy	IRC Section	Estimated Savings
S-Corp Election	IRC §1361	$15,000–$25,000/yr
QBI Deduction	IRC §199A	$5,000–$12,000/yr
Solo 401(k)	IRC §401(k)	$15,000–$23,000/yr
Augusta Rule	IRC §280A(g)	$3,000–$15,000/yr
Combined Total		$38,000–$75,000/yr

Each strategy is independent and additive. An S-Corp election reduces your self-employment tax. The QBI deduction reduces your income tax. A Solo 401(k) shelters income from tax entirely. The Augusta Rule creates tax-free rental income. Stack all four and you're looking at significant five-figure savings every year.

The 2026 Expiration: Why This Is Urgent

The QBI deduction was part of the TCJA, which is set to sunset after December 31, 2025. Unless Congress passes new legislation, Section 199A disappears entirely starting in 2026.

What this means for South Florida business owners:

2025 is potentially the last year to claim this deduction
If you haven't been claiming it, you may have missed years of savings (you can amend prior returns)
Your tax planning for 2025 should maximize QBI before the window closes
Income acceleration or deferral strategies may help you stay within favorable thresholds

Common Mistakes South Florida Business Owners Make

Not claiming it at all — Many sole proprietors don't realize they qualify
Wrong entity structure — Operating as a C-Corp when a pass-through would save more
Not paying enough W-2 wages — High earners need sufficient wages to maximize the deduction
Misclassifying as SSTB — Some businesses are incorrectly categorized, losing the deduction unnecessarily
Ignoring the phase-out math — Strategic income timing can keep you below thresholds
