How an LLC Files Taxes (Every Setup Explained)

An LLC files taxes according to its IRS classification. A single-member LLC reports on Schedule C with the owner's Form 1040. A multi-member LLC files Form 1065 as a partnership and issues K-1s to owners. An LLC that elects S-corporation status files Form 1120-S and pays owners a salary plus distributions. Texas LLCs also file an annual franchise tax report.

How the IRS decides what your LLC files

There is no federal form called an LLC return. The IRS does not tax an LLC as a thing in itself. It taxes it according to its classification, and that classification decides the form, the deadline, and who signs.

A one-owner LLC, a two-owner LLC, and an LLC that elected S corporation status can be identical legal entities at the state level while filing three completely different federal returns. That single fact is why the question "how does my LLC file taxes" only has a conditional answer: it depends on which box you are in.

Most single-member LLCs never file a separate federal business return.

The classification rules below are the same whatever year you read this in. Only the calendar dates move.

Single-member LLC: Schedule C with your Form 1040

One owner, no election filed: the IRS treats the LLC as a disregarded entity. The business sends no federal income tax return of its own. Everything reports on Schedule C, attached to your personal Form 1040, due April 15, 2026.

Schedule C lists the business income and expenses. The net profit then carries two charges at your personal level: income tax at your individual rates, and self-employment tax on that net profit. What comes off the top before either tax is computed matters more than most new owners expect, and the self-employed deductions guide walks through that side of the math.

One wrinkle catches single-member LLCs with employees. Employment tax filings, the payroll deposits and wage reports, happen under the LLC's own name and EIN, separate from your 1040, even though the income tax side never leaves your personal return.

Form 8832 exists if you ever want to elect corporate classification outright. In practice, owners who want corporate treatment usually take the S corporation route instead, because it carries its own dedicated form and rules, covered next.

Multi-member LLC: Form 1065 and K-1s

Add a second owner and the default flips to partnership taxation. The LLC files Form 1065, the partnership return, by Monday, March 16, 2026. March 15 is a Sunday, so the deadline slides to the next business day.

Form 1065 is an information return. The LLC reports its income and deductions, and the partnership itself generally pays no income tax. Each owner instead receives a Schedule K-1 showing their share of the results, and reports that share on their personal Form 1040.

The practical headache is sequencing. Your personal return cannot finish until your K-1 arrives, so a late 1065 makes every owner late. Partnerships that need more time file Form 7004, which moves the deadline to September 15, 2026.

LLC electing S corporation status: Form 1120-S

An LLC can elect S corporation treatment for federal taxes. The election form is Form 2553, and once it takes effect the LLC files Form 1120-S, on the same Monday, March 16, 2026 deadline as the partnership path.

The mechanics change how owners get paid. An owner who works in the business becomes an employee: compensation runs through payroll as a salary, and remaining profit comes out as distributions on top.

Whether the election actually saves money comes down to arithmetic. The salary-and-distribution split changes which earnings carry employment taxes, and the election adds costs of its own: payroll setup, deposits, and the wage filings that come with employees. At a healthy profit level the split can come out ahead. At a thin one, payroll costs can eat the difference. Run the numbers, or have them run, before filing Form 2553. Who should run them is its own question, and the CPA versus tax preparer comparison sorts out which setup fits which situation.

Texas LLCs: the franchise report sits on top

Federal classification does not touch state obligations. A Texas LLC files an annual franchise report with the Texas Comptroller, together with the Public Information Report, every year, including years when no franchise tax is due.

The franchise tax has its own base, its own threshold rules, and its own consequences for missed reports. The franchise tax guide covers what the report costs, how the no-tax-due threshold works, and what happens after a missed filing.

Common first-year mistakes

Four patterns show up over and over in a first LLC year.

• No quarterly estimates. Pass-through owners generally owe tax as the year runs, not only at filing time. The quarterly estimated taxes guide explains the safe harbors and the payment calendar.
• Mixed money. Business costs paid from a personal account, or the reverse, turn bookkeeping into archaeology and weaken the records behind every number on the return. A dedicated business account and monthly books fix it.
• The reflex election. Filing Form 2553 because another owner said "S-corp" at a networking event, before anyone ran the payroll-versus-savings numbers, is how LLCs end up with salary questions they cannot answer.
• Scattered documents. Entity paperwork, the EIN letter, bank statements, and receipts each live somewhere different until gathering season arrives. The small business tax preparation checklist lays out what to collect and when.
