Tax Deadlines Every Brevard County Small Business Should Know

Why tax deadlines trip up so many local businesses

If you run a small business in Melbourne, Palm Bay, Viera, or anywhere else in Brevard County, you already know the tax calendar never really stops. Federal returns, Florida sales tax, payroll deposits, and quarterly estimates all land on different dates, and missing one can mean penalties that add up fast.

The good news: once you understand the rhythm of the year, staying on time becomes routine. This guide walks through the deadlines that matter most for Brevard County small businesses, in plain English.

Note: exact dates shift slightly each year when they fall on weekends or holidays. Always confirm the current year’s dates with your accountant or the IRS and Florida Department of Revenue calendars.

What are the quarterly estimated tax deadlines?

If you’re a sole proprietor, partner, or S corporation owner who expects to owe tax at year-end, the IRS generally expects four estimated payments during the year:

• Q1: mid-April, covering income earned January through March
• Q2: mid-June, covering April and May
• Q3: mid-September, covering June through August
• Q4: mid-January of the following year, covering September through December

These payments cover both income tax and self-employment tax. A common mistake new Brevard County business owners make is treating their first profitable year like a paycheck job — nothing is withheld automatically, so the April surprise can be painful. Setting aside a percentage of every deposit into a separate savings account makes these dates far less stressful.

When are business tax returns due?

The filing deadline depends on how your business is structured:

• Sole proprietors and single-member LLCs file Schedule C with their personal return, due in mid-April.
• Partnerships and multi-member LLCs file Form 1065, due in mid-March — a month earlier than most people expect.
• S corporations file Form 1120-S, also due in mid-March.
• C corporations generally file Form 1120 by mid-April.

Extensions are available for all of these, but an extension to file is not an extension to pay. If you owe, the payment is still due on the original date.

What Florida-specific deadlines should Brevard County businesses know?

Florida has no personal state income tax, which is one reason so many entrepreneurs move here. But businesses still have state obligations:

• Florida sales tax: if you sell taxable goods or certain services, you collect and remit sales tax to the Florida Department of Revenue. Returns are typically due monthly or quarterly, on the 1st of the month following the reporting period, and considered late after the 20th.
• Reemployment (unemployment) tax: if you have employees, quarterly reports and payments are due at the end of the month following each quarter.
• Corporate income tax: Florida C corporations file a state corporate return, generally due by the first day of the fourth month after the tax year ends.
• Annual report: every Florida LLC and corporation must file an annual report with the state by May 1 to keep the business in good standing. Miss it and a steep late fee applies.

What payroll deadlines apply if I have employees?

Once you hire your first employee in Brevard County, a new layer of deadlines appears:

• Payroll tax deposits: federal income tax withholding and Social Security/Medicare taxes are deposited either monthly or semi-weekly, depending on your size.
• Form 941 (quarterly payroll return): due at the end of the month following each quarter.
• W-2s and 1099s: due to workers and the IRS by the end of January.

Payroll deadlines are the ones the IRS enforces most aggressively, so this is the area where professional help pays for itself fastest.

How can I make sure I never miss a deadline?

1. Put every date on one calendar at the start of the year, with reminders two weeks ahead.
2. Separate your tax money into its own account as revenue comes in.
3. Keep bookkeeping monthly, not yearly — you can’t estimate a quarterly payment accurately from a shoebox of receipts.
4. Work with a local accountant who tracks the calendar for you and flags what’s coming.

Frequently asked questions

What happens if I miss a quarterly estimated payment?

The IRS generally charges an underpayment penalty calculated as interest on the shortfall. Catching up at the next quarter usually limits the damage.

Do I owe Florida sales tax if I only sell services?

Many services are exempt in Florida, but some — like certain repairs and commercial cleaning — are taxable. It’s worth confirming your specific situation rather than assuming.

Is the Florida annual report the same as a tax return?

No. The annual report is a simple filing with the state Division of Corporations that keeps your business active. It’s separate from every tax return.
