Whether your LLC files its own federal tax return depends on how many owners it has and how it’s taxed. A single-member LLC doesn’t file a separate Florida LLC federal tax return; its profit goes on your personal Form 1040. A multi-member LLC files Form 1065, and an LLC that elected S corp or C corp status files a corporate return.
The upside of being in Florida: there’s no personal state income tax, so for most LLC owners the federal return is the only income tax return that matters.
Which federal return does a Florida LLC file?
The IRS has no “LLC” tax category. Your LLC defaults into an existing one or elects one:
| LLC type | Tax classification | LLC files | Owners file |
|---|---|---|---|
| Single-member (default) | Disregarded entity | No separate return | Schedule C + Schedule SE with Form 1040 |
| Multi-member (default) | Partnership | Form 1065 | Schedule E (from K-1) + Schedule SE with Form 1040 |
| S corp election | S corporation | Form 1120-S + payroll returns | W-2 wages + Schedule E (from K-1) on Form 1040 |
| C corp election | C corporation | Form 1120 | Dividend income on Form 1040 |
One Florida exception: Florida does have a corporate income tax, so an LLC that elects to be taxed as a C corporation also files a Florida corporate income tax return. LLCs taxed the default way, or as an S corp, generally don’t owe Florida income tax.
Single-member LLC: no separate return
If you’re the only owner, the IRS treats your LLC as a “disregarded entity.” The LLC doesn’t file anything on its own. You report its income and expenses on Schedule C (Profit or Loss from Business), attach it to your Form 1040, and calculate self-employment tax on Schedule SE.
Say Sunshine Consulting LLC brings in $100,000 and has $30,000 in business expenses. The owner reports $70,000 of net profit on Schedule C and pays self-employment tax at the 15.3% rate on it, on top of regular income tax.
You don’t need an EIN for the tax return itself if you have no employees, since you can report under your SSN. Most owners get one anyway because banks ask for it and it keeps your SSN off invoices and W-9s. Disregarded for tax purposes doesn’t mean disregarded legally, either: your liability protection is the same either way, as long as you keep business and personal money separate.
Multi-member LLC: Form 1065
Two or more members means your LLC is taxed as a partnership by default. The LLC files Form 1065 (U.S. Return of Partnership Income), an informational return. The LLC itself doesn’t pay income tax. Instead:
- The LLC files Form 1065 showing the business’s total income and deductions.
- Each member gets a Schedule K-1 showing their share.
- Each member reports their K-1 amounts on Schedule E of their own Form 1040 and pays self-employment tax through Schedule SE.
ABC Ventures LLC has two equal members and $200,000 in net profit. The LLC files Form 1065 showing $200,000. Each member gets a K-1 for $100,000 and reports it personally.
Form 1065 is due March 15 for calendar-year LLCs (the 15th day of the third month after the tax year ends). Form 7004 gets you an extension. File it even in a year with no profit. A missing partnership return draws penalties whether or not anyone owed tax.
Should your LLC elect S corp status?
An S corp election (Form 2553) changes the math on self-employment tax. Members who work in the business take a “reasonable salary” with payroll taxes withheld, and the remaining profit passes through without self-employment tax.
Here’s the rough comparison for a single-member LLC with $150,000 in net profit:
| Scenario | Payroll or self-employment tax |
|---|---|
| No election | About $21,000 in self-employment tax (15.3%, up to the Social Security wage base) |
| S corp election, $75,000 salary + $75,000 distribution | About $11,500 in FICA (7.65% employer + 7.65% employee on the $75,000 salary) |
| Difference | Roughly $9,500 saved |
The catch is paperwork: Form 1120-S, a Schedule K-1 (Form 1120-S) for each shareholder, payroll, a Form 941 every quarter and W-2s for owner-employees. The 1120-S has to be filed every year, even with no profit. And the salary has to actually be reasonable for the work you do.
The election usually starts making sense once the LLC consistently profits more than $50,000 to $60,000 a year and you actively work in it. Below that, the savings often don’t cover the extra payroll and accounting costs. We’d run your actual numbers with a tax professional before filing Form 2553.
What about a C corp election?
It’s rare for a small LLC. A C corporation files Form 1120 and pays tax at the corporate level, and then shareholders pay tax again on dividends (reported on Form 1099-DIV). Unless you have a specific reason, such as planning to raise venture capital, skip it.
What other federal filings might your LLC have?
If you have employees, you’ll file Form 941 quarterly (income tax and FICA withheld), Form 940 annually (federal unemployment tax, or FUTA), and W-2s for each employee each year, sent to the Social Security Administration with Form W-3.
If you pay contractors, you’ll file Form 1099-NEC for anyone you paid $600 or more.
If you expect to owe tax, you’ll likely need quarterly estimated payments on Form 1040-ES. Nobody withholds tax from LLC profits, so if you’ll owe more than $1,000 at year-end, skipping these can mean underpayment penalties.
| Estimated payment | Due date |
|---|---|
| Q1 | April 15 |
| Q2 | June 15 |
| Q3 | September 15 |
| Q4 | January 15 (of the next year) |
When are the returns due?
| Return | Due date (calendar-year filers) | Extension form |
|---|---|---|
| Form 1065 (partnership) | March 15 | Form 7004 |
| Form 1120-S (S corp) | March 15 | Form 7004 |
| Form 1040 (personal) | April 15 | Form 4868 |
| Form 1120 (C corp) | April 15 | Form 7004 |
An extension gives you more time to file, not more time to pay. Any tax you owe is still due by the original deadline.
Where new LLC owners usually slip
Self-employment tax is the usual surprise. People budget for income tax, forget the 15.3% on top and reach April with no estimated payments made. Set aside a share of every payment from day one.
The other is classification. Your default depends on how many members you have, and S corp and C corp elections only count if they were properly filed. Add a member and your single-member LLC becomes a partnership that needs a Form 1065.
When to bring in a CPA
You can handle a simple single-member Schedule C yourself. We’d get a CPA or tax attorney involved if you’re considering an S corp election, have multiple members with different ownership percentages, have employees, have complicated income or deductions, or are filing your first year in business. The first year is when the setup choices get made, and fixing them later costs more.
