For most owners, filing LLC taxes with personal taxes is the default. The IRS does not have a separate tax category called “LLC.” It classifies your business based on how many owners it has and whether you’ve filed an election to be taxed differently. A single-member LLC reports its income and expenses right on your Form 1040. A multi-member LLC files its own return but pays no tax at that level; the profit lands on each owner’s personal return. Only an LLC that has elected C corporation status pays tax as a separate business and keeps its income off your 1040 entirely.
So the honest answer is: it depends on which of the four possible tax classifications your LLC falls into. Three of them mean your LLC’s income shows up on your personal return. One doesn’t.
Single-Member LLC: One Return, Yours
If you’re the sole owner of your LLC and you’ve never filed an election with the IRS, your LLC is a “disregarded entity.” The IRS treats the business as if it doesn’t exist as a separate taxpayer.1Internal Revenue Service. Limited Liability Company (LLC) You still get the liability protection your state gives you for forming the LLC, but for federal tax purposes, you and the business file as one.
You report the LLC’s income and expenses on Schedule C, which attaches to your Form 1040.2Internal Revenue Service. Single Member Limited Liability Companies Schedule C lists gross receipts, subtracts cost of goods sold if applicable, and itemizes deductions like rent, supplies, insurance, and vehicle costs. The net profit or loss at the bottom of Schedule C flows to your 1040 and gets combined with your other income, whether that’s W-2 wages, investment income, or anything else.
There’s no separate business return to file. There’s no separate business tax to pay. Your LLC’s tax year is your tax year, and the deadline is your personal filing deadline.
One thing to keep in mind: because everything appears on your personal return, the IRS sees exactly what you’re deducting. Schedule C draws more scrutiny than most parts of a 1040. Keep receipts, mileage logs, and documentation for every business expense. That’s where audit problems usually start.
Multi-Member LLC: Two Returns, but Tax Only on Yours
When an LLC has two or more owners and hasn’t elected corporate treatment, the IRS classifies it as a partnership.3Internal Revenue Service. LLC Filing as a Corporation or Partnership Here the answer to “do I file with my personal taxes” gets more nuanced. The LLC does file its own return, but it doesn’t pay income tax. You still pay all the tax on your personal return.
The LLC files Form 1065 (U.S. Return of Partnership Income) by March 15 for a calendar-year business. Form 1065 is an information return: it reports the company’s total revenue, deductions, and net income, but it isn’t the return that pays the tax.4Internal Revenue Service. Instructions for Form 1065 – U.S. Return of Partnership Income (2025) From that return, the LLC issues each member a Schedule K-1 showing their share of the profits, losses, and other tax items.5Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income
You take your K-1 and report the numbers on your personal Form 1040. The income is taxed once, at your individual rate. Profit and loss splits follow your operating agreement, and those splits don’t have to match ownership percentages as long as they have a legitimate business purpose.
One trap catches new members: you owe tax on your allocated share of the profit whether the LLC actually distributed cash to you or not. If the business earned $200,000 and kept it all in the bank, you still owe tax on your share. This is sometimes called “phantom income,” and it’s why a well-drafted operating agreement addresses required tax distributions.
LLC Taxed as an S Corporation: Salary Plus K-1 on Your 1040
An LLC can elect S corporation tax treatment by filing Form 2553.6Internal Revenue Service. About Form 2553, Election by a Small Business Corporation This is the election people usually mean when they talk about an LLC “saving on self-employment taxes.” The S corp is still a pass-through, so income still flows to your personal return. What changes is how you get paid.
The LLC files Form 1120-S annually, another information return with no corporate-level tax due.7Internal Revenue Service. About Form 1120-S, U.S. Income Tax Return for an S Corporation The return generates a K-1 for each owner. But any owner who works in the business must also receive a “reasonable salary” through payroll, reported on a W-2.8Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers
On your personal 1040 you report both pieces: the W-2 salary on the wages line, and the K-1 income on the pass-through line. The W-2 salary is subject to Social Security and Medicare tax. Profit beyond the salary comes to you as a distribution reported on the K-1 and generally isn’t subject to the 15.3% self-employment tax.
Say your LLC earns $150,000 and you pay yourself a $70,000 salary. Only that $70,000 gets hit with payroll taxes. The other $80,000 flows through the K-1 and is taxed at ordinary income rates without the self-employment tax layer. The IRS takes “reasonable” seriously, though. Pay yourself $20,000 for work that would cost $70,000 to hire out, and the IRS can reclassify distributions as wages and assess back payroll taxes, penalties, and interest.9Internal Revenue Service. Wage Compensation for S Corporation Officers
Not every LLC qualifies. The IRS caps S-Corp shareholders at 100, requires all of them to be U.S. citizens or residents (no partnerships or corporations as owners), and allows only one class of stock.10Internal Revenue Service. S Corporations Foreign investors or entity members put S-Corp status off the table.
LLC Taxed as a C Corporation: Filed Separately
The C corporation election is the one classification where you truly don’t file the LLC’s taxes with your personal taxes. The LLC files Form 8832 to elect corporate classification.11Internal Revenue Service. About Form 8832, Entity Classification Election From that point forward, the business files its own Form 1120 and pays a flat 21% federal corporate income tax on its profits.12Internal Revenue Service. Instructions for Form 1120 (2025)
The LLC’s operating income and losses never touch your 1040. You only report money you personally receive from the corporation: W-2 wages if you work there, or dividends when the company distributes after-tax profits. That’s the setup that produces “double taxation” — the corporation pays tax on its profits, then you pay tax again on dividends. Qualified dividends get the lower capital gains rate, which softens the impact, but for most small businesses the total tax is higher than pass-through treatment.
C-Corp status generally fits LLCs planning to raise outside investment, keep significant earnings inside the business at the 21% rate, or pursue venture capital. For a typical small business that pays its profits to its owners, the double taxation usually outweighs the benefit.
Self-Employment Tax on the Pass-Through Profit
When your LLC is a disregarded entity or a partnership, the net profit that flows to your personal return also triggers self-employment tax. This covers Social Security and Medicare — the same taxes a W-2 employee splits with their employer, except here you pay both halves.
The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.13Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The Social Security portion applies only to the first $184,500 of combined wages and self-employment income in 2026.14Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Above that ceiling, only the 2.9% Medicare piece continues, with no cap.
You calculate self-employment tax on Schedule SE and report it on Form 1040. Net earnings are first reduced by multiplying by 92.35% to approximate the deduction W-2 employees effectively get. After calculating the tax, you can deduct half of it as an above-the-line deduction, which lowers your income tax (but not the self-employment tax itself).
S-Corp owners avoid self-employment tax on the distribution portion of their income (only the W-2 salary is hit with payroll taxes). C-Corp owners don’t pay self-employment tax at all because they receive wages or dividends instead. This gap is the main financial reason LLC owners consider moving off the default classification.
Quarterly Estimated Payments
Because no employer withholds taxes from your LLC profit, the IRS expects you to pay as you earn. You send estimated payments using Form 1040-ES, with four deadlines for 2026: April 15, June 15, and September 15 of 2026, plus January 15, 2027.15Internal Revenue Service. 2026 Form 1040-ES Estimated Tax for Individuals You can skip the January payment if you file your 2026 return and pay the balance by February 1, 2027.
You avoid the underpayment penalty if you meet any of these:
- Your total tax due at filing is less than $1,000.
- Your estimated payments covered at least 90% of the current year’s tax liability.
- Your estimated payments covered at least 100% of last year’s total tax (110% if last year’s AGI was over $150,000, or $75,000 married filing separately).16Office of the Law Revision Counsel. 26 USC 6654 – Failure by Individual to Pay Estimated Income Tax
The prior-year safe harbor is the most useful tool for LLC owners whose income swings from year to year. If last year’s total tax was $30,000 and your AGI was under $150,000, sending $7,500 per quarter guarantees no penalty no matter how much more you earn. New businesses without a prior year have to lean on the 90% current-year method.17Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty
Changing How Your LLC Is Taxed
Your default classification isn’t permanent, and switching changes whether the LLC gets filed with your personal return.
For S-Corp status, file Form 2553. To take effect for the current tax year, the form must be filed no later than two months and 15 days after the tax year begins — for calendar-year LLCs, that’s March 15. You can also file during the preceding tax year.18Internal Revenue Service. Instructions for Form 2553 (12/2020) Miss the deadline and there’s a late-election relief procedure that generally gives you up to three years and 75 days from the intended effective date, provided you can show reasonable cause, all owners agree, and everyone has been filing consistently with S-Corp treatment.
For C-Corp status, file Form 8832. The effective date can’t be more than 75 days before you file the form and can’t be more than 12 months after.19Internal Revenue Service. Form 8832 (Rev. December 2013)
Once you make a classification change via Form 8832, you generally can’t make another change for 60 months from the effective date.20Internal Revenue Service. Limited Liability Company – Possible Repercussions An election a brand-new LLC makes on formation doesn’t count as a “change” for this purpose. Switching from C-Corp back to pass-through does start the clock.
Before filing either election, check your operating agreement. S-Corp status requires the equivalent of one class of stock, meaning all owners must have identical distribution and liquidation rights.10Internal Revenue Service. S Corporations Preferential distributions or economic-interest-based voting can block the election until the agreement is amended. State filing requirements and franchise taxes are separate and continue regardless of your federal classification, so confirm those with your Secretary of State’s office as well.
