For federal tax purposes, LLC income is personal income for almost every owner. The IRS treats the standard LLC as a pass-through entity, so the company’s profits skip the business return and land directly on the owner’s Form 1040, taxed at individual rates. The one exception is an LLC that has elected to be taxed as a C corporation. Everything else about how you report, what extra taxes apply, and when you pay them follows from that basic fact.1Internal Revenue Service. LLC Filing as a Corporation or Partnership
Why LLC Profit Becomes Your Income
Pass-through taxation means the LLC itself doesn’t pay federal income tax. The net profit is calculated at the business level, then flows to the owners, who report their share on their personal returns and pay tax at their own marginal rates.1Internal Revenue Service. LLC Filing as a Corporation or Partnership
The LLC is still a separate legal entity for liability purposes. The IRS just ignores that separation when calculating income tax. From the tax code’s perspective, the money the business earns is your money the moment it’s earned, whether you withdraw it or leave it in the company bank account.
How Each Classification Reports Income
The IRS gives an LLC four possible tax classifications, and each one changes how the income shows up on your personal return. If you never file an election, the default depends on how many owners the LLC has.
Single-Member LLC
A single-member LLC is automatically a disregarded entity. The IRS treats all business activity as if you conducted it personally, and you report the net profit or loss on Schedule C, attached to your Form 1040.2Internal Revenue Service. Single Member Limited Liability Companies The profit is taxed at whatever marginal rate applies to your total income for the year. There’s no separate business return.
Multi-Member LLC
When two or more people own an LLC, it defaults to partnership taxation. The LLC files Form 1065, an informational return that reports total income, deductions, and credits but doesn’t generate a tax bill for the business.3Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income Each owner receives a Schedule K-1 showing their share of profit or loss, and that K-1 number goes onto their personal Form 1040. Ownership percentages and profit-sharing terms in the operating agreement determine how much gets allocated to each member.
S Corporation Election
An LLC can elect S corporation taxation by filing Form 2553.4Internal Revenue Service. About Form 2553, Election by a Small Business Corporation The legal structure doesn’t change, only the tax treatment. Income still passes through to the owner’s personal return, but in two pieces. An owner who works in the business must take a reasonable salary reported on a W-2. Any remaining profit is distributed through a Schedule K-1. Both pieces are personal income; they just get treated differently for payroll tax purposes.
The IRS scrutinizes what counts as reasonable compensation. There’s no bright-line rule; courts look at the owner’s training, duties, time devoted to the business, and what similar companies pay for comparable work.5Internal Revenue Service. Fact Sheet 2008-25, S Corporation Reasonable Compensation Setting an artificially low salary to shift income into distributions is one of the fastest ways to attract an audit, and courts have consistently ruled against owners who try to recharacterize wages that way.6Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers
C Corporation Election: The Exception
An LLC that elects C corporation status by filing Form 8832 is the one case where business income does not automatically become personal income. The LLC files Form 1120 and pays corporate income tax at the entity level, currently a flat 21%.7Internal Revenue Service. About Form 1120, U.S. Corporation Income Tax Return The business keeps its after-tax profits until it distributes them.
When profits are distributed as dividends, the owner pays tax again on the personal return. That double taxation is why most small LLCs avoid this election. It typically makes sense only for businesses that plan to reinvest most profits rather than distribute them, or that need a traditional corporate structure to attract outside investors.
Self-Employment Tax on Pass-Through Income
Income tax isn’t the only bill that follows from personal-income treatment. Owners of pass-through LLCs also owe self-employment tax, which funds Social Security and Medicare. It’s an additional 15.3% on top of income tax, and no employer is covering half of it for you.
The 15.3% breaks down into 12.4% for Social Security and 2.9% for Medicare. The tax doesn’t apply to every dollar of net profit; the IRS first reduces your net self-employment earnings to 92.35% before calculating the tax, which approximates the deduction traditional employers get on their share of payroll taxes.8Internal Revenue Service. Topic No. 554, Self-Employment Tax The 12.4% Social Security portion only applies to earnings up to the annual wage base, which is $184,500 for 2026.9Social Security Administration. What Is the Maximum Amount of Earnings Subject to Social Security Tax Above that cap, only the 2.9% Medicare tax continues.
High earners face an extra layer. Self-employment income above $200,000 for single filers or $250,000 for joint filers triggers an Additional Medicare Tax of 0.9% on the excess.10Internal Revenue Service. Questions and Answers for the Additional Medicare Tax The IRS combines wages and self-employment income when measuring against these thresholds.
You calculate self-employment tax on Schedule SE and file it with your Form 1040.11Internal Revenue Service. About Schedule SE (Form 1040), Self-Employment Tax You can deduct half of the self-employment tax as an adjustment to income, which reduces your AGI and lowers your income tax without reducing the self-employment tax itself.8Internal Revenue Service. Topic No. 554, Self-Employment Tax
S corporation owners get the most significant break. Only the W-2 salary is subject to FICA taxes. The remaining profit distributed through a K-1 is not subject to those payroll taxes.6Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers That split is the main reason LLCs elect S corp status, though the savings have to cover the cost of running payroll, filing a separate return, and defending a reasonable salary if the IRS asks.
The 20% Qualified Business Income Deduction
Personal-income treatment comes with a specific offset for pass-through owners. Under Section 199A, eligible LLC owners can deduct up to 20% of their qualified business income from taxable income.12Office of the Law Revision Counsel. 26 USC 199A – Qualified Business Income On $100,000 of LLC profit, that’s a $20,000 deduction before you get to the standard or itemized deduction. The provision was made permanent by legislation signed in 2025.
The deduction is straightforward below certain income thresholds. For 2026, limitations begin phasing in at approximately $203,000 for single filers and $406,000 for joint filers. Above those levels, the deduction may be reduced or eliminated depending on the type of business and how much it pays in W-2 wages.
Service-based businesses like law firms, medical practices, consulting firms, and financial advisory practices face the tightest restrictions. Owners in these fields lose the deduction entirely once income exceeds the phaseout range. Owners of non-service businesses may still qualify above the threshold, but the deduction is limited based on W-2 wages paid and the value of qualified property held by the business. The deduction is available whether you itemize or take the standard deduction. C corporations are excluded, since this is specifically a pass-through benefit.
Paying Tax Throughout the Year
Because no employer withholds taxes from your LLC income, you pay the IRS as you earn. If you expect to owe $1,000 or more in tax after withholding and refundable credits, quarterly estimated payments are required.13Internal Revenue Service. Form 1040-ES, Estimated Tax for Individuals
The 2026 deadlines are:
- First quarter (January through March): April 15, 2026
- Second quarter (April through May): June 15, 2026
- Third quarter (June through August): September 15, 2026
- Fourth quarter (September through December): January 15, 2027
Missing these payments triggers an underpayment penalty even if you settle the full balance when you file. To avoid the penalty, your payments must cover at least 90% of the current year’s tax liability or 100% of last year’s tax (110% if your prior-year AGI exceeded $150,000).13Internal Revenue Service. Form 1040-ES, Estimated Tax for Individuals The 100% safe harbor based on last year’s tax is the easier target for most owners, especially in years when income fluctuates.
Taxable Profit vs. Cash You Take Out
This is where personal-income treatment trips up new owners: you owe tax on your share of the LLC’s profit whether or not you actually move the money to your personal account. If your LLC earns $80,000 and you leave every dollar in the business, you still owe income tax and self-employment tax on that $80,000.
The profit figure on your Schedule C or Schedule K-1 sets your tax liability. Draws and distributions are separate events. Those cash transfers aren’t independently taxable because the underlying profit was already taxed when the LLC earned it.
For owners taxed as partners, distributions are tax-free up to your basis in the LLC. Basis is your total investment in the company: initial capital contributions plus accumulated taxed profits, minus prior distributions and losses. Cash taken out above basis is taxable as a capital gain.12Office of the Law Revision Counsel. 26 USC 199A – Qualified Business Income Tracking basis accurately is one area where a good accountant earns the fee.
State Treatment
Federal pass-through treatment is only part of the picture. Most states with an income tax also treat LLC income as personal income and tax it on the owner’s state return. Rates range from zero in states without an income tax to over 13% in the highest-tax states.
Some states impose additional entity-level taxes or fees on the LLC regardless of federal classification, including annual franchise taxes, gross receipts taxes, or minimum fees based on total revenue. These sit on top of the personal income tax the owner pays on the same profits. Check your state’s specific requirements, because failing to pay an annual LLC fee can result in the state administratively dissolving the company.
