What South Florida Business Owners Need to Know About Taxes in 2026

Every year brings a new round of federal tax changes, phase-outs, and expiring provisions, and every year, the business owners who come out ahead are the ones who planned before December instead of reacting in April. If you run a business in Miami-Dade, Broward, or Palm Beach County, here is where your attention should be right now.

Why Mid-Year Is the Real Tax Season

By the time your return is being prepared, almost every meaningful planning opportunity has already closed. Depreciation elections, retirement plan contributions tied to compensation, entity structure changes, and timing decisions on income and expenses all have to happen during the tax year, not after it ends. A mid-year check-in gives you six months of actual results to project from and six months of runway to act. That combination is what makes strategy possible.

A good mid-year review answers three questions: Where will taxable income land if nothing changes? Which elections and deductions are still available to move that number? And are your estimated payments tracking with reality, or are you drifting toward an underpayment penalty?

Expiring and Changing Provisions: Do Not Assume Last Year's Rules Apply

Congress has spent the last several years extending, modifying, and sunsetting business provisions on a rolling basis. Rules covering bonus depreciation percentages, research and experimental cost treatment, interest expense limitations, and the qualified business income (QBI) deduction have all been in motion. Some provisions that lapsed have been restored; others carry scheduled phase-downs baked into the law.

The practical takeaway is simple: never plan a major purchase, a large distribution, or a year-end bonus strategy based on what the rule was two years ago. Confirm the current-year treatment first. The difference between a full first-year write-off and a multi-year depreciation schedule can change the economics of an equipment purchase entirely.

Depreciation Planning Deserves Its Own Conversation

For contractors, transportation companies, medical practices, and any business buying vehicles, machinery, or technology, depreciation strategy is often the single largest planning lever available. You generally have several tools to choose from:

• Section 179 expensing, which lets you deduct qualifying property in the year placed in service, subject to annual limits and income restrictions that change with inflation adjustments.
• Bonus depreciation, whose first-year percentage has been subject to legislative changes, confirm the current figure before you rely on it.
• Regular MACRS depreciation, which spreads deductions over the asset's recovery period and is sometimes the smarter choice when you expect higher income in future years.

The right answer depends on your current bracket, your expected trajectory, your state footprint, and whether accelerating deductions would waste them against income that is already lightly taxed. Owners of commercial real estate should also ask whether a cost segregation study makes sense, reclassifying building components into shorter recovery periods can meaningfully accelerate deductions on recently purchased or renovated property.

Florida-Specific Considerations

Florida remains famously friendly to individual taxpayers, with no personal state income tax. But businesses here are not tax-free. C corporations face the Florida corporate income tax, tangible personal property tax returns are due annually in most counties for business equipment, and sales and use tax compliance trips up more South Florida businesses than almost anything else, particularly contractors and companies buying equipment out of state. If your business has grown into other states through remote work, deliveries, or job sites, nexus questions deserve a serious look before another state finds you first.

Your 2026 Mid-Year Checklist

1. Project full-year taxable income using actual results through June.
2. Recalculate quarterly estimates and adjust the remaining payments.
3. Review planned equipment and vehicle purchases against current depreciation rules.
4. Confirm your entity structure still fits, profit levels change, and so does the answer.
5. Revisit retirement plan options while there is still time to establish or fund one.
6. Check payroll, sales tax, and tangible property filings for gaps.

Plan Now, Not in April

Tax law rewards the prepared. The provisions in play this year are too significant, and too fluid, to navigate with a once-a-year conversation at filing time.
