Does a Single-Member LLC File Schedule C? Disregarded Entity Taxes (2026)

Q: Does a single-member LLC file a Schedule C?

Yes. By default a single-member LLC (SMLLC) is treated as a 'disregarded entity' for federal income tax, meaning the IRS ignores the LLC and treats the business as a sole proprietorship owned by you. You report all of the LLC's income and expenses on Schedule C, which attaches to your personal Form 1040. The LLC does not file its own separate federal income tax return unless it has elected to be taxed as a corporation. So forming an LLC, by itself, does not change how you file — you still use Schedule C.

Q: What does 'disregarded entity' mean for taxes?

A disregarded entity is a business that legally exists (the LLC is real for liability and state-law purposes) but is 'disregarded' — ignored — for federal income tax. The IRS looks straight through the LLC to its single owner and taxes the activity on the owner's return. For an individual owner, that means Schedule C; the LLC's profit becomes your profit. The status is automatic for a single-member LLC unless you file Form 8832 or Form 2553 to be taxed as a corporation.

Q: Does a single-member LLC pay self-employment tax?

Yes. Because the net profit flows to your Schedule C, it is subject to self-employment tax (about 15.3% for Social Security and Medicare) just like any sole proprietor's profit. Forming an LLC does not reduce self-employment tax on its own — that only changes if you elect S-corporation taxation and pay yourself a reasonable W-2 salary, leaving the remaining profit free of SE tax. Until you make that election, an SMLLC and a sole proprietor owe identical self-employment tax.

Q: Should a single-member LLC use an EIN or SSN on Schedule C?

On Schedule C itself, a disregarded SMLLC generally reports under the owner's name and Social Security number, because the return is the individual's. However, you can — and often should — obtain an EIN for the LLC to open a business bank account, give to clients on a Form W-9, and avoid putting your SSN on paperwork. If you have employees or pay certain excise taxes, the LLC must use its own EIN for those filings. So: EIN for banking, payroll, and W-9s; the income still lands on your personal Schedule C.

Q: When should a single-member LLC stop filing Schedule C?

Switch away from Schedule C when you elect corporate taxation. Filing Form 2553 makes the LLC an S corporation, which files Form 1120-S and pays you a W-2 salary plus K-1 distributions — this can cut self-employment tax once profits are high enough (often around $40,000–$80,000 of net profit, after weighing payroll and accounting costs). Filing Form 8832 to be a C corporation moves you to Form 1120. Adding a second member turns the LLC into a partnership filing Form 1065. Until one of those happens, you stay on Schedule C.

TL;DR: A single-member LLC (SMLLC) is a disregarded entity by default — the IRS ignores the LLC for income tax and treats you as a sole proprietor, so you report the business on Schedule C of your personal Form 1040. The LLC files no separate federal income tax return unless it elects corporate status. You still owe self-employment tax on the profit and pay quarterly estimates. Get an EIN for banking and W-9s even though your SSN anchors the return. The filing only changes when you elect S-corp (Form 2553 → Form 1120-S), C-corp (Form 8832 → Form 1120), or add a partner (Form 1065).

You formed an LLC for liability protection, and now tax season is here. The most common question — and the most common myth — is whether the LLC changes how you file. For a single-member LLC, the answer for 2026 is reassuringly simple: nothing about your federal filing changes. You file the same Schedule C a sole proprietor files. Here's why, and what to actually do.

What "disregarded entity" really means

When you form a single-member LLC, you create a separate legal entity under state law — that's what gives you the liability shield. But for federal income tax, the IRS default rule is to disregard that entity. It looks through the LLC to its one owner and taxes the business activity on the owner's return as though the LLC didn't exist.

For an individual owner, "the owner's return" means Form 1040 with a Schedule C attached. Your LLC's revenue is your gross receipts; its expenses are your deductions; its profit is your profit. The LLC does not file its own income tax return.

So the LLC is real for lawsuits, contracts, and your bank — and invisible to the IRS for income tax. That dual nature is the whole point of "disregarded entity."

Where the numbers go: still Schedule C

Because the IRS treats you as a sole proprietor, every line works the same way it would without the LLC. See how to fill out Schedule C for the full walk-through; the short version:

Item	Where it goes
Business income (all of it)	Schedule C Line 1
Ordinary, necessary expenses	Schedule C Part II lines 8–27a
Vehicle/mileage	Line 9 (car & truck)
Home office	Line 30
Net profit or loss	Line 31 → flows to Form 1040
Self-employment tax	Schedule SE

The LLC name can appear in the Schedule C header (Line C, business name), but the return is filed under you. There is no separate LLC tax return to prepare. Categorize as you would any sole proprietor — our Schedule C categories guide maps each expense to its line.

You still pay self-employment tax

This is the deduction-saving truth that surprises new LLC owners: an LLC does not lower your self-employment tax. Your Schedule C net profit flows to Schedule SE and is hit with roughly 15.3% for Social Security and Medicare — exactly the same as a sole proprietor with no LLC. See self-employment tax explained.

You also still:

Pay quarterly estimated taxes on the profit (guide)
May claim the 20% QBI deduction, subject to the usual rules (QBI for freelancers)
Deduct self-employed health insurance above the line (how)

The LLC changed your liability exposure, not your tax math.

EIN vs. SSN: use both, for different jobs

A disregarded SMLLC sits in an odd spot on tax IDs. Here's the practical rule:

On Schedule C / Form 1040: the return is yours, so your SSN is the taxpayer ID for income tax.
For banking, W-9s, and clients: get an EIN for the LLC. It lets you open a business account and hand clients an EIN instead of your SSN — better privacy and cleaner records. See EIN vs. SSN on Schedule C.
For payroll or excise taxes: if the LLC has employees, it must use its own EIN for employment-tax filings, even while income still lands on your Schedule C.

Bottom line: an EIN is worth getting; it just doesn't move where the income is reported.

When the filing actually changes

You leave Schedule C only when you change the LLC's tax classification or ownership:

Elect S-corporation taxation (Form 2553)

The LLC becomes an S corp, files Form 1120-S, and pays you a reasonable W-2 salary plus profit distributions. Done right, this can shave self-employment tax off the distribution portion. It usually pays off once net profit is consistently high — often roughly $40,000–$80,000+ — after accounting for payroll, bookkeeping, and a separate return. Weigh it carefully: see S-corp election for freelancers and LLC vs. sole proprietor taxes.

Elect C-corporation taxation (Form 8832)

Less common for freelancers; the LLC files Form 1120 and is taxed as a separate corporation.

Add a second member

Two or more members make the LLC a partnership by default, filing Form 1065 and issuing K-1s — Schedule C no longer applies.

Until you do one of these, your default disregarded SMLLC stays on Schedule C.

Recordkeeping: the LLC raises the bar

A disregarded entity is taxed simply, but the liability shield only holds if you respect the LLC as separate. Keep a dedicated business bank account, never commingle personal and business spending, and keep clean, line-by-line expense records — both to protect the shield and to defend your deductions.
