LLC tax rates and rules for tax year 2025

If you’re wondering what the LLC tax rate is, the short answer is: there isn’t one fixed rate. LLC profits are taxed at your personal income tax rate, plus self-employment tax, depending on how your business is structured.

For tax year 2025, your total LLC tax burden depends on your income level, filing status, state, and whether you elect pass-through, S corporation, or C corporation taxation. Understanding how these pieces fit together helps you estimate what you’ll owe and plan ahead.

What is an LLC?

An LLC (limited liability company) is a business structure that protects your personal assets while allowing profits to pass through to your personal tax return. That pass-through structure is why there’s no standalone LLC tax rate at the federal level.

Like a sole proprietorship or partnership, an LLC’s profits are taxed at the owner’s individual income tax rate unless you elect corporate taxation. At the same time, you get liability protection similar to a corporation, which shields your personal assets from business debts and lawsuits.

How LLCs are taxed

By default, LLCs are taxed as pass-through entities. That means the LLC itself does not pay federal income tax. Instead, profits pass directly to you and any other members, and you report that income on your personal return.

What pass-through taxation means for your LLC

With pass-through taxation, business income flows through the LLC to its owners, who pay tax at their individual rates. This structure avoids double taxation, which occurs when profits are taxed at the corporate level and again when distributed to owners as dividends.

Default tax classification by LLC type

The IRS assigns a default tax classification based on the number of members in your LLC, though you can elect a different treatment if it makes financial sense:

• Single-member LLC: Taxed as a sole proprietorship (a “disregarded entity” for federal tax purposes)
• Multi-member LLC: Taxed as a partnership by default
• Election options: Any LLC can elect to be taxed as an S corporation or C corporation

Single-member LLC tax rate

If you're the sole owner of your LLC, here's how your tax rate works.

A single-member LLC is treated as a sole proprietorship for income tax purposes. The LLC does not pay taxes as a separate entity. Instead, the owner reports the LLC's expenses and business income on their personal income tax return, typically using Schedule C of Form 1040. The LLC's profits are taxed at the individual's personal income tax rate, and the owner also pays self-employment tax on the profits.

The self-employment tax rate is 15.3%, covering Social Security (12.4%) and Medicare (2.9%) taxes. For the 2025 tax year, Social Security tax applies to earnings up to $184,500, and Medicare tax applies to all net earnings, with an additional 0.9% surtax on earnings over $200,000 for individuals.

Multi-member LLC tax rate

A multi-member LLC is taxed as a partnership by default, meaning the LLC itself does not pay federal income tax. Instead, profits and losses pass through to the members, who report their share on their personal tax returns.

Each active member generally pays income tax and self-employment tax on their distributive share of the LLC’s net income, even if profits aren’t fully distributed.

Partnership tax treatment

Multi-member LLCs file Form 1065, an informational return that reports the LLC’s total income, deductions, and credits. The LLC does not pay entity-level federal income tax under this structure. Instead, the IRS taxes each member individually on their share of the profits.

Form 1065 and Schedule K-1 reporting

Each member receives a Schedule K-1, which outlines their share of profits, losses, deductions, and credits based on the LLC’s operating agreement. Members use the K-1 to complete their personal tax returns. Unless the LLC elects S corporation taxation, active members typically owe self-employment tax on their share of net earnings.

LLC income tax rates

LLC owners pay personal income tax rates on business profits, not a separate corporate tax rate. Your LLC tax rate depends on your total taxable income and filing status.

Federal tax brackets for LLC owners

Because LLC income passes through to you (unless you elect C corp taxation), federal income tax brackets determine how your profits are taxed. The U.S. tax system uses marginal rates, meaning different portions of your income are taxed at different rates as your income increases.

In addition to federal income tax, you may also owe:

• State income tax or annual LLC fees
• Self-employment tax
• Payroll tax
• Sales tax

How your tax bracket affects LLC profits

Your LLC income stacks on top of your other earnings, such as W-2 wages, investment income, or a spouse’s income on a joint return. That means your LLC profits are taxed starting at your highest marginal rate, not from the 10% bracket.

For example, if you earn $80,000 from a day job and your LLC generates $50,000 in net profit, that $50,000 is taxed beginning in the bracket where your salary leaves off. Understanding this stacking effect helps you estimate your real effective tax rate and avoid underpaying quarterly estimates.

Self-employment tax for LLC owners

In addition to income tax, most active LLC owners pay self-employment tax on net earnings. This tax covers your Social Security and Medicare contributions and applies whether your LLC is single-member or multi-member (unless you elect S corp taxation and pay yourself wages).

Self-employment tax is 15.3% total, representing both the employer and employee portions that W-2 workers typically split.

Social Security tax

The Social Security portion is 12.4%. For the 2025 tax year, it applies to net self-employment earnings up to $184,500. Income above that threshold is not subject to additional Social Security tax.

Medicare tax

The Medicare portion is 2.9% and applies to all net self-employment earnings with no cap. If your total earnings exceed $200,000 as a single filer (or $250,000 if married filing jointly), you’ll owe an additional 0.9% Medicare surtax on the amount above those thresholds.

LLC taxed as an S corporation

An LLC can elect to be taxed as an S corporation to potentially reduce self-employment taxes. Instead of paying self-employment tax on all profits, you pay payroll taxes only on a reasonable salary, and remaining profits can be distributed without the 15.3% self-employment tax.

You make this election by filing Form 2553 with the IRS.

How S corp election reduces self-employment tax

As an S corp owner-employee, you must pay yourself a reasonable salary through payroll. That salary is subject to Social Security and Medicare taxes.

Any remaining profit can be distributed as dividends, which are not subject to self-employment tax. The tax savings come from splitting income between salary (taxed for payroll purposes) and distributions (not subject to self-employment tax).

The IRS requires that your salary be “reasonable” for the work you perform. Paying yourself artificially low wages to minimize payroll taxes can trigger penalties.

Requirements for S corp election

To qualify for S corp status, your LLC must meet specific IRS requirements:

• Must be a domestic LLC
• No more than 100 shareholders
• Only one class of stock
• All shareholders must be eligible individuals, certain trusts, or estates

LLC taxed as a C corporation

An LLC can elect to be taxed as a C corporation, which subjects the business to a flat 21% federal corporate income tax rate. Unlike pass-through taxation, the LLC pays tax at the entity level.

To make this election, you file Form 8832 with the IRS.

The trade-off is double taxation: the LLC pays corporate income tax on profits, and any dividends distributed to owners are taxed again on their personal returns.

When C corp election makes sense

C corporation taxation isn’t common for small LLCs, but it can make sense in certain situations:

• Retaining significant profits: If you plan to reinvest most earnings, the 21% corporate rate may be lower than your personal marginal rate
• Seeking outside investors: Venture capital firms and institutional investors often prefer C corp structures
• High personal tax brackets: Owners in the 35% or 37% brackets may benefit from the lower corporate rate on retained income

Before making this election, run the numbers with a tax professional. Double taxation on distributed profits can quickly outweigh the benefits.

State taxes and annual LLC fees

Your LLC tax rate doesn’t stop at the federal level. Most states impose their own income taxes, franchise taxes, or annual fees, and these can materially increase your total tax burden.

State income tax on LLC profits

In most states, LLC income is taxed through to the owners just like it is federally. Your share of LLC profits is added to your personal state income tax return and taxed at your state’s individual rates.

Some states don’t impose personal income tax, including Texas, Nevada, Florida, and Wyoming. Others have high top rates. New York’s top marginal rate reaches 10.9%, and California’s can reach 12.3% for high-income earners. Where you operate can significantly affect your effective tax rate.

Franchise taxes and annual fees

Some states charge LLCs an annual tax or franchise fee regardless of profitability. These are mandatory ongoing compliance costs:

• California: $800 annual LLC tax, plus an additional fee ranging from $900 to $11,790 for LLCs with gross receipts over $250,000
• Delaware: $300 annual franchise tax for LLCs
• Texas: Franchise (margin) tax on LLCs above the revenue threshold, typically 0.375% of gross receipts for most entities
• Nevada: No state income tax, but a $200 annual business license fee and potential modified business tax based on gross wages

Before forming or relocating an LLC, evaluate both income tax exposure and recurring state fees. The cheapest state to form an LLC isn’t always the cheapest state to operate in.

Additional taxes for LLC owners

Income tax and self-employment tax aren’t the only obligations you may face. If your LLC has employees or sells taxable goods or services, you may also owe payroll taxes and sales tax.

Payroll taxes

If your LLC has employees, you must withhold and remit payroll taxes. These include:

• Social Security and Medicare taxes: Employers and employees split these taxes. For 2025, Social Security tax is 12.4% on wages up to $184,500, and Medicare tax is 2.9% on all wages. An additional 0.9% Medicare surtax applies to wages over $200,000 for individual taxpayers.
• Federal unemployment (FUTA) tax: 6% on the first $7,000 of each employee’s wages, typically reduced by state unemployment tax credits

You must also withhold federal income taxes from employee wages and file:

• Form 941: Filed quarterly to report withheld income taxes and Social Security and Medicare taxes
• Form 940: Filed annually to report federal unemployment taxes

Sales tax

If your LLC sells taxable goods or services, you must collect and remit sales tax to the appropriate state and local authorities. Rates vary widely by state and locality.

Sales tax obligations depend on nexus, which is your business’s connection to a state. Nexus can be created through physical presence (office, employees, inventory) or economic activity above certain sales thresholds. For example, California requires out-of-state sellers to collect sales tax if they exceed $500,000 in annual sales into the state.

If you have nexus, you must:

• Register with the state revenue department
• Collect sales tax on taxable transactions
• File returns and remit collected tax on a required schedule

Staying compliant with payroll and sales tax requirements protects your LLC from penalties and costly audits.

How to calculate how much business tax you’ll pay

You can estimate your LLC tax bill by combining income tax and self-employment tax. Running this calculation early helps you plan cash flow and avoid underpayment penalties.

Estimating your effective tax rate

Your effective tax rate equals total tax divided by total income. For LLC owners, that typically includes both income tax and self-employment tax.

Follow these steps:

1. Calculate net business profit: Total revenue – Deductible business expenses
2. Calculate self-employment tax: Multiply net profit by 92.35%, then multiply that result by 15.3%
3. Add business income to other income: Stack LLC profit on top of W-2 wages, investment income, or other earnings
4. Apply marginal tax brackets: Use federal (and state, if applicable) income tax brackets to estimate income tax owed

Most LLC owners land in a combined effective range of roughly 25–40%, depending on income level and state.

Quarterly estimated tax payments

Because no taxes are automatically withheld from LLC profits, you must make estimated tax payments throughout the year using Form 1040-ES.

For tax year 2025, payments are generally due:

• April 15, 2025: Income earned January–March
• June 15, 2025: Income earned April–May
• September 15, 2025: Income earned June–August
• January 15, 2026: Income earned September–December

To avoid penalties, many LLC owners use the IRS safe harbor rule: pay at least 100% of last year’s total tax liability (or 110% if your adjusted gross income exceeded $150,000).

How to reduce your LLC tax burden

You can’t avoid taxes, but you can legally reduce how much you pay. The key is combining deductions, tax elections, and proactive planning.

Qualified Business Income deduction

The qualified business income (QBI) deduction allows eligible LLC owners to deduct up to 20% of qualified business income from taxable income. This applies to pass-through entities, including single-member and multi-member LLCs.

However, income limits apply. If your taxable income exceeds $197,300 (single) or $384,600 (married filing jointly) for 2025, the deduction may phase out depending on your business type. Specified service trades or businesses, such as law or consulting, face stricter limitations at higher income levels.

Maximizing deductible business expenses

Every legitimate deduction reduces your taxable income. Common deductions LLC owners should track include:

• Home office expenses (space used regularly and exclusively for business)
• Business travel and transportation
• Equipment, supplies, and software
• Professional services (legal, accounting, consulting)
• Health insurance premiums for self-employed individuals
• Business insurance
• Advertising and marketing
• Retirement contributions (SEP IRA or Solo 401(k))

Consistent expense tracking throughout the year makes these deductions easier to capture and defend.

Choosing the right tax election

Your default tax classification isn’t always the most efficient option. Electing S corp status can reduce self-employment taxes if your profits significantly exceed a reasonable salary. For businesses reinvesting substantial profits, C corp taxation may lower the rate on retained earnings.

There’s no universal answer. Modeling different scenarios with a tax professional can reveal meaningful savings.
