Introduction
Pass-through taxation means your business income skips corporate-level tax and flows directly onto your personal tax return, where it's taxed once at your individual rate. Most small businesses — sole proprietorships, partnerships, LLCs, and S Corporations — qualify by default. This guide covers how it works, which structures use it, and where the trade-offs are.
What pass-through taxation is
Pass-through taxation is a tax treatment where the business itself doesn't pay federal income tax. Instead, the business's profits, losses, deductions, and credits pass through to the owners' personal tax returns, and each owner pays tax at their individual income tax rate. The IRS recognizes several business structures as pass-through entities by default.
You'll also hear this called flow-through taxation — same concept, different name. The key distinction from a C Corporation is that a C Corp pays tax at the entity level first, and then shareholders pay tax again on any dividends they receive. Pass-through entities avoid that second layer entirely.
Which business structures qualify
Four main business structures qualify for pass-through tax treatment. Most small businesses fall into one of these categories without needing to make any special election.
Sole proprietorship
A sole proprietorship is the simplest pass-through structure. You report all business income and expenses on Schedule C, which attaches to your personal Form 1040. There's no separate business tax return to file.
Partnership
Partnerships file an informational return (Form 1065) but don't pay income tax at the entity level. Each partner receives a Schedule K-1 showing their share of income, deductions, and credits, which they report on their personal return.
Limited Liability Company (LLC)
LLCs are pass-through entities by default. A single-member LLC is taxed like a sole proprietorship; a multi-member LLC is taxed like a partnership. Owners can also elect to have the LLC taxed as an S Corporation or C Corporation if that's more advantageous for their situation.
S Corporation
An S Corporation elects pass-through status under Subchapter S of the tax code. Income passes to shareholders via Schedule K-1. One important difference: S Corp owners who work in the business must pay themselves a reasonable salary as a W-2 employee before taking distributions.
How pass-through taxation works in practice
Pass-through taxation means the business's profit lands on each owner's personal return in proportion to their ownership share — not as a paycheck, but as taxable income they report and pay tax on directly.
Take 2 equal co-owners of a consulting business. Their business earns $100,000 in net profit for the year. The business pays no federal income tax on that amount. Instead, each owner reports $50,000 on their personal return and pays tax at their individual rate. If one owner is in the 22% bracket and the other is in the 24% bracket, each pays their own rate on their $50,000 share.
Losses work the same way. If the business has a bad year and posts a $40,000 loss, each owner can potentially deduct $20,000 against other income on their personal return, subject to IRS basis and at-risk rules. That's a real advantage early-stage businesses don't get with a C Corporation.
Benefits of pass-through taxation for small business owners
Pass-through taxation offers 3 concrete advantages for most small business owners: no double taxation, simpler filing, and access to the 20% qualified business income (QBI) deduction.
No double taxation
C Corporations pay federal income tax on profits at the entity level, and then shareholders pay tax again on dividends. Pass-through entities skip the first layer. Your business income is taxed once — on your personal return — at your individual rate.
Simpler filing
Sole proprietors and single-member LLC owners report business income on Schedule C — no separate business return required. Partnerships and S Corps do file informational returns (Form 1065 and Form 1120-S respectively), but the tax liability still flows to the owners' personal returns rather than being settled at the entity level.
The 20% qualified business income deduction
Eligible pass-through business owners may deduct up to 20% of their qualified business income (QBI) under Section 199A of the tax code. This deduction is only available to pass-through entities — C Corporations don't qualify. Income limits and restrictions apply depending on your business type and total taxable income, so a tax professional can help you figure out whether you qualify and how much you can deduct.
Trade-offs to know before you decide
Pass-through taxation isn't the right fit for every business. There are 3 trade-offs worth understanding before you commit to a structure.
Self-employment tax
Sole proprietors and partners pay self-employment tax (15.3% on net earnings up to the Social Security wage base) on top of income tax. S Corp owners can reduce this exposure by splitting income between a reasonable salary and distributions — but the salary portion still triggers payroll taxes. This is one of the most common reasons business owners explore the S Corp election.
Phantom income
In a partnership or multi-member LLC, you owe tax on your share of the business's profit even if the business didn't distribute cash to you. If the business reinvests its earnings, you can end up paying tax on income you never actually received. This catches people off guard more than almost anything else in pass-through taxation.
Higher personal rates at scale
Pass-through income is taxed at your personal rate, which tops out at 37% for high earners. The current federal corporate tax rate is 21%. Once a business is generating significant profit, the math can shift — and a C Corporation structure may produce a lower overall tax bill. A tax professional can help you figure out where that crossover point is for your specific situation.
Pass-through taxation vs. corporate taxation
The core difference comes down to where the tax bill lands. With pass-through taxation, the business pays no federal income tax — the owners do, on their personal returns. With corporate taxation (C Corporation), the business pays tax first at the 21% corporate rate, and shareholders pay tax again on any dividends received.
For most small businesses, pass-through treatment is the better starting point. You avoid double taxation, you can use business losses to offset other personal income, and you may qualify for the 20% QBI deduction. The C Corporation structure tends to make more sense when a business is retaining large amounts of profit inside the entity, seeking outside investors, or planning to go public.
- Pass-through: income taxed once, on the owner's personal return
- C Corporation: income taxed at 21% at the entity level, then again on dividends
- Pass-through owners may qualify for the 20% QBI deduction; C Corp shareholders don't
- C Corps can retain earnings at the lower corporate rate — useful for reinvestment-heavy businesses
- S Corps combine pass-through treatment with some payroll tax advantages over sole proprietorships and partnerships
FAQ
A pass-through entity is a business structure where the business itself doesn't pay federal income tax. Instead, profits, losses, deductions, and credits pass through to the owners' personal tax returns. Sole proprietorships, partnerships, LLCs, and S Corporations are all pass-through entities by default under IRS rules.
Yes. LLCs are pass-through entities by default. A single-member LLC is taxed like a sole proprietorship; a multi-member LLC is taxed like a partnership. LLC owners can also elect to be taxed as an S Corporation or C Corporation by filing the appropriate form with the IRS, but the default treatment is always pass-through.
It depends. For most small business owners, pass-through taxation is the better starting point — you avoid double taxation, can deduct business losses against personal income, and may qualify for the 20% QBI deduction. The trade-offs are self-employment tax on net earnings and the risk of phantom income in partnerships. At higher profit levels, a C Corporation's 21% flat rate can become more attractive. A tax professional can help you figure out which structure fits your situation.
Both are pass-through entities, but the S Corporation structure adds a payroll tax advantage. In a default LLC, all net profit is subject to self-employment tax (15.3% up to the Social Security wage base). In an S Corp, owner-employees pay themselves a reasonable salary — which triggers payroll taxes — but distributions above that salary are not subject to self-employment tax. The S Corp election makes sense once the business is generating enough profit to justify the added payroll administration.
The main pass-through tax benefit is the Section 199A qualified business income (QBI) deduction, which lets eligible pass-through business owners deduct up to 20% of their qualified business income from taxable income. Income limits apply, and certain service businesses face additional restrictions. This deduction is only available to pass-through entities — C Corporations don't qualify. Talk to a tax professional to figure out whether your business and income level qualify.
Yes. Tax credits available to pass-through entities flow through to the owners' personal returns the same way income and deductions do. Each owner claims their proportionate share of any eligible credits on their individual return. Common examples include the general business credit and certain energy credits. The specific credits available depend on your business type and activities.
Pass-through income is taxed at each owner's personal income tax rate, which ranges from 10% to 37% depending on total taxable income and filing status. There's no single flat rate — each owner pays based on their own tax bracket. If you qualify for the 20% QBI deduction, that reduces the amount of pass-through income subject to tax before your rate is applied.
