How to Calculate LLC Taxes? (2026 Business Guide)
To calculate LLC taxes, start with your net profit, apply the 15.3% self-employment tax, then layer in your federal income tax bracket and any applicable state taxes.
I've spent over a decade as a corporate attorney helping entrepreneurs structure their LLCs — and I've watched this process cost owners thousands when they get it wrong.
The exact amount you owe depends on your LLC's tax classification: sole proprietor, partnership, S-Corp, or C-Corp. This guide walks you through each one.
Quick Summary
- To calculate LLC taxes, you need your gross income, effective tax rate, deductions, and savings.
- Online calculators can get you to a precise number faster, but you still need to understand what goes into it.
- Per IRS guidelines, self-employment taxes cover Social Security and Medicare — totaling 15.3% on the first $184,500 in 2026 [1].
- Multi-member LLCs can elect to be taxed as a C-Corp or S-Corp, which changes the math significantly.
How to Calculate LLC Taxes?
LLC taxes are less complicated than most people expect. Here's how to work through them accurately.
"Each business entity type carries specific tax implications, and for numerous business proprietors, limited liability companies (LLCs) present distinct tax advantages when compared to other corporate structures."

Calculating Self Employment Taxes
Self-employment taxes are often the number that surprises new LLC owners the most. Social Security and Medicare apply to the first $184,500 of your net earnings, at a combined rate of 15.3% for the 2026 tax year — straight from IRS guidelines.
Here's how that breaks down:
The Social Security portion is 12.4%, covering income up to $184,500. It accounts for both the employee and employer sides, since you're paying both. The Medicare portion is 2.9% on all income — no cap — and that one's on you alone.
I've seen self-employment tax catch first-time founders off guard. Even if your income tax rate is lower, self-employment tax can quietly become one of your biggest out-of-pocket expenses for the year. Plan for it early.
Calculating Federal Income Taxes
Start with your Adjusted Gross Income (AGI) — that's your baseline for both federal and state income tax calculations.
To get there, take your self-employed net earnings and subtract any self-employment taxes you've paid. From there, you can apply deductions. The standard deduction and the Section 199A (QBI) deduction are the two we've used most often for our LLC, and both can meaningfully reduce what you owe.
A few other things worth knowing: long-term capital gains are taxed at 0%, 15%, or 20% depending on your taxable income and filing status — well below ordinary income rates. Short-term capital gains, though, get taxed at your regular marginal rate. That distinction matters if you're selling assets [2].
Calculating The Estimated Income Tax
If you expect to owe $1,000 or more in business income taxes for the year, the IRS requires you to make quarterly estimated payments — not one lump sum at filing time.
The four due dates are April 15, June 15, September 15, and January 15. Miss one, and you're looking at interest and penalties on top of what you already owe.
To figure out what to pay each quarter, estimate your annual income and calculate the tax on that amount. The IRS Estimated Tax Worksheet is the clearest tool for this — it walks you through the calculation without much guesswork.
How is an LLC Taxed?
An LLC is taxed as a pass-through entity by default. That means the LLC itself doesn't pay income tax — profits and losses flow directly to the owners, who report them on their personal returns.
Single Member LLC Taxation
The IRS treats a single-member LLC as a disregarded entity for federal income tax purposes. In practice, that means you report business income and expenses on Form 1040, Schedule C — the same form sole proprietors use.
Multi-Member LLC Taxation
Multi-member LLCs are treated as pass-through entities for federal income tax purposes. Each member pays taxes on their share of the LLC's income based on their ownership percentage — so your effective LLC tax rate depends on your individual bracket.
Most states require their own versions of Form 1065 and Schedule K-1, which track and distribute income the same way the federal forms do [3].
C Corporation Taxation
Your LLC can elect to be a C corporation by submitting Form 8832 to the IRS (your state may also demand additional forms for a tax status change) [4].
If you make this choice, your LLC will be subject to the 21% federal corporate tax rate. You'll file taxes using Form 1120, which is the form used for all US corporations.
C-corporations are subject to double taxation. This means that the company pays taxes on its profits, and then the shareholders—the owners of the C-corp—pay income taxes on their dividends and capital gains.
To avoid this, we recommend choosing to have your LLCs taxed as S-corporations.
S Corporation Taxation
To acquire the S-corporation tax status, submit Form 2553 to the IRS. An S-Corp is taxed like a pass-through entity, similar to an LLC, except that it is not taxed on salary or distributions from the company.
To submit taxes for an S-Corp, complete and file Form 1120S.
A corporation's business income is taxed differently than an LLC's, and corporations are entitled to greater deductions and tax breaks.
Additional LLC Taxes
Beyond the basics, there are several other taxes your LLC might owe depending on where you operate and what industry you're in. Don't assume your tax picture ends at self-employment and income tax.
LLC Payroll Taxes
If your LLC has employees, you're responsible for collecting and remitting payroll taxes — that includes unemployment taxes, Social Security, and Medicare.
Social Security and Medicare are split between employer and employee under FICA. You handle your half; your employees handle theirs through withholding.
Report unemployment taxes on IRS Form 940. Use Form 941 for everything else — Social Security, Medicare, and federal income tax withholding.
LLC Self-Employment Taxes
The overall self-employment tax rate is 15.3%, with each portion having a separate name:
- $0 to $184,500: 12.4% social security tax on earnings.
- On all earnings, you'll have to pay the 2.9% Medicare tax.
- The 0.9% Medicare surtax applies to wages above $200,000 (or $250,000 for joint filers).
LLC Sales Taxes
If you're a sole proprietorship or a single-member LLC selling taxable goods or services, you'll need to collect sales tax from customers and remit it to your state or local tax authority.
Rules vary a lot by state, so I'd recommend talking to an accountant who knows your specific location and industry before you assume you're covered.
LLC Tax Tips for Business Owners
After working with LLC owners across a range of industries, these are the tax practices I've seen make the biggest difference — both in what people actually owe and in how much time they spend on filing. Here are a few that apply to lessen the tax burden and keep the process manageable.
The LLC tax filing tips include:
- Claim every deduction and credit your LLC qualifies for — don't leave money on the table.
- Track income tax due dates ahead of time and pay on schedule. Late payments cost more than the taxes themselves.
- Hire a CPA or tax attorney. For most LLC owners, the fee pays for itself.
- Talk to your CPA about whether electing S-Corp or C-Corp status makes sense for your LLC — the tax savings can be real, but it depends on your profit level.
- Know your state and local tax rules. They're not the same everywhere.
How the QBI Deduction Reduces Your LLC Tax Bill
The Qualified Business Income (QBI) deduction under Section 199A lets eligible LLC owners deduct up to 20% of their net business income from taxable income — which directly cuts what you owe [5].
Congress made it permanent in July 2025. The full deduction applies to single filers with taxable income below $203,000, or $406,000 for married filing jointly.
Here's what that looks like in practice: an LLC owner with $100,000 in net profit could reduce their taxable income by $20,000 — saving roughly $4,400 at a 22% marginal rate. That's not nothing.
One catch: certain service-based LLCs in law, health, and consulting hit income-based phase-out restrictions before they reach those thresholds.
