Small Business Taxes in North Miami: What Owners Owe & Deduct in 2026
Running a North Miami LLC? You have four tax deadlines a year — not one. Here's how to stay compliant and keep more of what you earn.
Federal quarterly estimates
If you'll owe more than $1,000, pay quarterly — Apr 15, Jun 15, Sep 15, Jan 15. Underpayment triggers 8% IRS penalties in 2026.
Florida sales tax = 7% in Miami-Dade
6% state + 1% Miami-Dade surtax. If you sell tangible goods or taxable services, register with the Florida DOR and file monthly, quarterly, or annually based on volume.
S-Corp reasonable compensation
Most North Miami service businesses save $8K–$18K/yr with an S-Corp election — but the IRS requires 'reasonable' salary before distributions. Get the split wrong and you invite an audit.
Top overlooked deductions
Home office, vehicle mileage (67¢/mi in 2026), health insurance, cell phone, professional development, Section 199A QBI, and retirement plan contributions.
Bookkeeping saves the return
Clean books = maximum deductions and 3x faster prep. I include quarterly bookkeeping review with annual tax prep for North Miami clients.
