Income Tax Return for Businesses in Florida

All businesses are required to file an annual income tax return with the IRS. The process varies slightly depending on the business type — for example, partnerships are not taxed at the entity level but must file an informational return (Form 1065) to report income, deductions, and other financial details, while the individual partners report their share of the income on their personal tax returns.

The specific tax form you must file depends on your business structure — whether it's a Limited Liability Company (LLC), S Corporation, C Corporation, Partnership, or Sole Proprietorship — as each type has its own filing requirements and tax treatment under federal law.

The federal income tax system operates on a pay-as-you-go basis, meaning that taxes must be paid as income is earned or received throughout the year, rather than in a single payment at the end of the year. These ongoing payments are known as Estimated Taxes, and they help businesses and individuals stay compliant and avoid potential penalties for underpayment.

Employment Taxes

When your company is ready to hire employees, you as the employer have certain responsibilities like employment tax, that must be paid and forms you must file. Employment taxes include the following:

  • Social security and Medicare taxes
  • Federal income tax withholding
  • Federal unemployment (FUTA) tax

All employers are required to make federal payroll tax payments to the government and at the same time, file a report. Companies that have direct employees or hire contractors are required to yearly report to the IRS the payments made to those employees or contractors using the forms W2 and 1099 respectively. Rules can be a bit complex for a small company owner, that is why this service is often outsourced.

Handling payroll tax responsibilities involves the following:

  • Federal and state taxes are paid and reported
  • Income reporting (forms W2), amounts withheld (forms W4), and amounts paid on behalf of employees (forms 940 & 941) and contractors (Form 1099) are correct and file or send on time.
  • Required federal and state records are kept

What Types of Businesses Do We Serve?

  • LLCs (Single-Member and Multi-Member) — Each with different filing requirements and tax treatment.
  • S-Corporations — Ideal for business owners looking to reduce self-employment tax through salary and distribution splitting.
  • C-Corporations — For businesses planning to scale, attract investment, or issue multiple classes of stock.
  • Partnerships — With their specific Form 1065 information return requirements.
  • New businesses in Florida — Getting tax obligations right from day one saves costly corrections later.
  • Foreign-owned businesses operating in the U.S. — Needing guidance on the American tax system, in English or Spanish.

The Enrolled Agent Advantage:
Real IRS Protection

An Enrolled Agent is a federally licensed tax practitioner with unlimited rights to represent taxpayers before the IRS — a level of authority that many CPAs and most tax preparers simply don't hold. To earn this designation, Susana Rivera passed all three parts of the IRS Special Enrollment Examination and meets strict continuing education requirements. Her credentials — a B.S. in Accounting, a B.S. in Finance, and an M.S. in Accounting, all from Florida International University (FIU) — back that designation with deep academic foundation. What this means for your Miami business: when an IRS letter arrives, Susana responds on your behalf. If an audit is triggered, she handles it. If back taxes need to be negotiated, she's fully authorized to do so. This is not a common capability among Miami-area bookkeeping and accounting firms — it's a meaningful differentiator that protects your interests.

Estimated tax

Generally, you must pay taxes on income, including self-employment tax, by making regular payments of estimated tax during the year.  Even if you made partial payments throughout the year, you may still need to pay any tax due when you file your annual tax return.  These payments are like the tax withheld from any individual’s pay/salary.

For most businesses and individuals, Estimated Tax Payments are made four times per year. The standard due dates are as follows:

  • 1st Payment: April 15 — for income earned from January 1 through March 31
  • 2nd Payment: June 15 — for income earned from April 1 through May 31
  • 3rd Payment: September 15 — for income earned from June 1 through August 31
  • 4th Payment: January 15 (of the following year) — for income earned from September 1 through December 31

Excise taxes

Are taxes imposed on goods, services and activities. Excise taxes may be imposed on the manufacturer, retailer or consumer, depending on the specific tax. Examples of excise taxes for which may include:

  1. Petroleum Tax
  2. Superfund Chemical Excise Taxes Reinstated
  3. Excise Tax on Coal
  4. Kerosene Used in Aviation - Form 720 Tax Liability Reporting
  5. Extended Fuel Tax Credits
  6. Sports Wagering
  7. Heavy Highway Vehicle Use Tax
  8. Excise Tax on Indoor Tanning Services

Self-Employment Tax

Self-employment tax accounts primarily for Social Security and Medicare taxes for individuals who work for themselves. It is like the Social Security and Medicare taxes withheld from the paychecks of direct company employees. Self-employed individuals must figure the amount using Schedule SE (Form 1040 or 1040-SR). Also, you can deduct the employer-equivalent portion of your SE tax in figuring your adjusted gross income. Wage earners cannot deduct Social Security and Medicare taxes.

The self-employment tax rate is 15.3%. The rate consists of two parts: 12.4% for social security and 2.9% for Medicare.

Frequently Asked Questions About
Corporate Taxes in Miami

What's the difference between an LLC and an S-Corp for tax purposes?

A single-member LLC is treated by default as a 'disregarded entity' — all income passes through to your personal return (Schedule C of Form 1040) and is subject to self-employment (SE) tax at 15.3% on net profit. An S-Corp allows the owner to be an employee, paying SE tax only on a 'reasonable salary' — distributions above that salary are not subject to SE tax. For business owners with net income over roughly $50,000/year, an S-Corp election can produce meaningful tax savings. We recommend evaluating this structure during a planning consultation.

Can you represent me if I get audited by the IRS?

Yes. Our IRS Enrolled Agent, Susana Rivera, is fully authorized to represent any taxpayer or business before any IRS office nationwide — including audits, CP2000 notices, payment plans, offers in compromise, and appeals. You don't need to appear or hire a tax attorney. We handle it.

When are corporate tax returns due in Florida?

Key filing deadlines: March 15 for Partnerships, Multi-Member LLCs, and S-Corps; April 15 for C-Corps and Sole Proprietors. Extensions are available. Quarterly estimated tax payments are due April 15, June 15, September 15, and January 15. Note: Florida has no personal state income tax, but C-Corps pay a 5.5% Florida Corporate Income Tax.

What happens if I haven't filed my business taxes for previous years?

Unfiled returns are more common than you might think, and the solution is always to address them proactively. We can help you get current on back taxes, communicate directly with the IRS on your behalf, and request penalty abatement where applicable. The sooner you act, the more options you have — waiting invites liens, levies, and escalating penalties.

Does Florida have a state corporate income tax in addition to federal?

Florida has no personal state income tax, making it one of the most business-friendly states in the country. However, C-Corporations are subject to the Florida Corporate Income Tax at 5.5% on net income. LLCs, S-Corps, and Partnerships are exempt from this state tax. All businesses with employees are subject to Florida Reemployment Tax (the state equivalent of FUTA).

Can I deduct business expenses if I operate as an LLC?

Yes. LLCs can deduct all legitimate business expenses: office rent, equipment, software, business travel, salaries, marketing, insurance, and more. Good bookkeeping throughout the year is essential to capturing every deduction available. Our bookkeeping and corporate tax services are designed to work together to maximize your tax advantages.
