LLCs don't pay federal income tax as a business — you do, on your personal return

An LLC itself does not file or pay federal income tax. Instead, the IRS treats an LLC as a pass-through entity, meaning the business's income passes through to the owners' personal tax returns. You report the LLC's profits and losses on your own federal return and pay tax at your individual rate. The LLC files an informational return with the IRS (Form 1065 if there are multiple owners, or nothing if you're a sole proprietor), but that form does not result in a tax bill to the business itself.

How much you actually owe depends on how many owners the LLC has and whether you've made a special election with the IRS. Most single-owner LLCs are taxed as sole proprietorships. Most multi-owner LLCs are taxed as partnerships. Both are pass-through structures. If you want the LLC taxed as a corporation instead, you can file Form 8832 with the IRS to make that election — but that's uncommon and changes the entire tax picture.

Key Takeaways

  • An LLC with one owner is taxed as a sole proprietorship on your personal return unless you elect corporate taxation.
  • An LLC with multiple owners is taxed as a partnership, and each owner reports their share of profit or loss on their personal return.
  • You report LLC income on Schedule C (sole proprietor) or Schedule E (partnership), not on a separate business tax return.
  • Self-employment tax on LLC income is your responsibility, calculated on Schedule SE and paid with your personal return.
  • The LLC itself files an informational return with the IRS, but you pay the actual tax bill as an individual.

Single-Owner LLCs and Personal Tax Returns

If you own an LLC by yourself, the IRS treats it as a sole proprietorship for tax purposes unless you file Form 8832 to elect corporate status. This means you report all the LLC's income and expenses on your personal federal return using Schedule C (Profit or Loss from Business). The net profit or loss from Schedule C flows into your main 1040 return and is taxed at your individual income tax rate.

You also owe self-employment tax on the LLC's net income. Self-employment tax covers Social Security and Medicare for self-employed people. You calculate it on Schedule SE and pay it along with your income tax. The self-employment tax rate is approximately 15.3 percent of your net earnings (the exact rate and income cap change yearly). This is in addition to federal income tax, not instead of it.

The LLC itself does not file a federal income tax return. You file only your personal 1040 with the schedules attached. If your LLC has employees or certain other circumstances, you may need to file other forms (like employment tax returns), but those are separate from your income tax obligation.

Multi-Owner LLCs and Partnership Taxation

If your LLC has more than one owner, the IRS treats it as a partnership for tax purposes by default. The LLC files Form 1065 (U.S. Return of Partnership Income) with the IRS by the deadline (usually March 15 for calendar-year businesses). Form 1065 is informational only — the partnership itself pays no tax.

Instead, the LLC calculates each owner's share of profit or loss and issues a Schedule K-1 to each owner. The Schedule K-1 shows your portion of the LLC's income, deductions, credits, and other tax items. You then report this information on your personal return, typically on Schedule E (Supplemental Income and Loss). Your share of the LLC's profit is added to your other income and taxed at your individual rate.

Like sole proprietors, LLC owners in a partnership also owe self-employment tax on their share of the business income. You calculate this on Schedule SE using the net earnings from your Schedule K-1. Each owner pays self-employment tax individually based on their ownership stake and the LLC's profitability.

When an LLC Elects to Be Taxed as a Corporation

You can file Form 8832 (Entity Classification Election) to have your LLC taxed as a corporation instead of a pass-through entity. If you do this, the LLC becomes a C corporation for tax purposes and files its own federal income tax return (Form 1120). The corporation pays tax on its profits at the corporate tax rate (currently a flat 21 percent). Any money the corporation distributes to you as dividends is then taxed again at your individual rate — this is called double taxation.

Most small business owners do not elect corporate taxation because of this double tax. However, some situations make it worthwhile: if the LLC will retain earnings in the business rather than distribute them to owners, or if the owners want to take a salary and deduct it as a business expense. This is a complex decision that depends on your specific circumstances and income level.

If you elect corporate taxation, you must file Form 8832 by the deadline (usually 60 days after the LLC is formed or the election is effective). Once filed, the election generally stays in place until you revoke it or the IRS terminates it.

Quarterly Estimated Tax Payments

Because the IRS does not withhold taxes from LLC income the way an employer withholds from a paycheck, you are responsible for paying estimated tax four times a year. Estimated tax covers both income tax and self-employment tax on the income you expect to earn.

You calculate estimated tax using Form 1040-ES and pay it by the quarterly deadlines: April 15, June 15, September 15, and January 15 of the following year. If you do not pay enough in estimated taxes throughout the year, you may owe a penalty when you file your annual return, even if you are due a refund. The penalty is calculated based on how much you underpaid and how late the payment was.

Many LLC owners set aside a portion of each month's income to cover estimated taxes, then pay the quarterly amounts on time. This prevents a large tax bill at filing time and avoids penalties.

Deductions and Expenses You Can Report

The main advantage of LLC taxation is that you can deduct legitimate business expenses from your income before calculating tax. Common deductions include rent or mortgage on a home office, equipment and supplies, vehicle expenses, insurance, professional fees, and wages paid to employees. You report these deductions on Schedule C (sole proprietor) or on the partnership return (multi-owner LLC).

Keep records of all business expenses: receipts, invoices, bank statements, and mileage logs. The IRS may ask to see these records if you are audited. Deductions reduce your taxable income, which lowers both your income tax and your self-employment tax.

Some expenses are not deductible, such as personal expenses, fines or penalties, and certain meals and entertainment. If you are unsure whether an expense qualifies, consult a tax professional or review IRS Publication 334 (Tax Guide for Small Business).

Frequently Asked Questions

Do I have to file taxes if my LLC made no profit?

You must still file your personal return if you meet the income threshold for your filing status, even if the LLC had no profit. However, if the LLC had a loss, you can report that loss on your return, which may reduce your overall tax bill or generate a refund. If the LLC is a multi-owner partnership, Form 1065 must be filed regardless of profit or loss.

What if I have an LLC but also work a regular job?

Report your W-2 wages from your job on your 1040 as usual. Report your LLC income on Schedule C or Schedule E, depending on whether you are a sole proprietor or partner. Both income sources are combined on your return and taxed together. You may owe estimated tax on the LLC income if your employer is not withholding enough from your paycheck to cover your total tax liability.

Can I deduct losses from my LLC on my personal return?

Yes, if your LLC has a net loss, you can report that loss on your personal return, which reduces your taxable income from other sources. However, there are limits: passive activity loss rules may restrict how much loss you can deduct in a given year, and you cannot deduct more than you invested in the LLC. Consult a tax professional if your LLC has significant losses.

Do I need to pay state income tax on LLC income?

Most states tax LLC income the same way the federal government does — as pass-through income on your personal return. However, some states impose a separate LLC tax or franchise tax on the business itself, regardless of profit. Check your state's tax website or consult a tax professional to understand your state's rules.
