Pass-Through Taxation Explained: LLCs, S Corps, and Partnerships

Pass-through taxation means business income is taxed only once, at the owner’s personal tax return, avoiding double taxation

Pass-through taxation means business income is not taxed at the corporate level but instead flows directly to the owners, who report it on their personal tax returns

What Is Pass-Through Taxation?

Pass-through taxation lets business income be taxed once at the owner level, avoiding double taxation faced by C corporations. It applies to sole proprietorships, partnerships, LLCs, and S corporations. LLCs offer liability protection; S corps reduce self-employment taxes through salaries and dividends; partnerships allow flexible profit sharing but require self-employment tax.

Benefits include simpler filing, tax savings, and the 20% Qualified Business Income deduction. Compliance and state tax rules vary, so professional advice is recommended to optimize benefits and choose the best structure.

According to recent reports, about 95% of U.S. businesses operate as pass-through entities such as LLCs, S corporations, or partnerships, with only a minority choosing the C corporation model

Pass-Through Taxation by Entity Type

LLCs (Limited Liability Companies)

Limited Liability Companies (LLCs) offer flexible taxation options. Single-member LLCs are taxed as disregarded entities, with income reported on the owner’s personal tax return. Multi-member LLCs are taxed like partnerships unless they elect corporate taxation.

LLC owners report profits and losses on individual tax returns, avoiding corporate income tax. LLCs also provide liability protection, separating personal assets from business debts. They can choose to be taxed as an S corporation or C corporation, allowing tailored tax strategies to fit financial goals while complying with IRS rules.

S Corporations

S corporations are a special type of corporation that elects pass-through taxation by filing Form 2553 with the IRS. Unlike C corporations, S-corps do not pay federal income tax at the corporate level. Instead, income, deductions, and credits pass through to shareholders, who report them on personal tax returns.

A key benefit is paying owner-employees a reasonable salary while distributing remaining profits as dividends, potentially reducing self-employment taxes. However, S corps face strict eligibility rules, such as limits on shareholders, and must follow specific operational protocols like holding meetings and keeping records. This structure suits small to medium businesses that meet the criteria, offering corporate benefits without double taxation.

Partnerships

Partnerships, including general partnerships and limited partnerships, use pass-through taxation by default. The partnership files an informational return (Form 1065) but does not pay income tax. Each partner receives a Schedule K-1 showing their share of income, deductions, and credits, which they report on their individual tax returns.

Partnerships allow flexible profit and loss allocation through partnership agreements, reflecting partners’ contributions and risk levels. However, partners generally pay self-employment taxes on their share of income. This structure enables pooling resources and expertise, sharing financial risks, and fostering collaboration among partners.

Key Benefits of Pass-Through Taxation

Key Benefits of Pass-Through Taxation

• Avoids double taxation: income is taxed once at the individual level, not twice like C corporations.

• Simpler tax filing: pass-through entities typically file fewer forms compared to corporations.

• Flexibility in profit allocation: partnerships and LLCs can allocate profits and losses according to agreements, not strictly ownership percentage.

• Qualified Business Income (QBI) deduction: eligible owners may deduct up to 20% of their business income, reducing overall tax liability.

• Tax planning opportunities: owners can offset business income with other deductions, credits, or investment losses.

• Encourages reinvestment: lower effective taxes free up cash flow to grow the business.

The Qualified Business Income (QBI) Deduction

The QBI deduction allows eligible pass-through business owners to deduct up to 20% of their qualified business income from their taxable income. This deduction applies to income from LLCs, S corporations, partnerships, and sole proprietorships, subject to certain limitations and thresholds.

However, the QBI deduction is complex and includes various restrictions based on the type of business, the taxpayer’s income level, and the wages paid by the business. For example, certain service businesses like health, law, and consulting may face limitations if income exceeds specified thresholds. Understanding these nuances is essential to maximizing the benefit of the QBI deduction.

Here are concrete examples to illustrate savings:

Scenario	Qualified Business Income (QBI)	QBI Deduction (20%)	Estimated Tax Savings*
Sole proprietor with QBI = $100,000 in the 22% tax bracket	$100,000	$20,000	~$4,400 saved in taxes (Nolo)
Married couple filing jointly with $300,000 taxable income and $225,000 QBI via an S corporation (paying owner W-2 wages of $125,000)	$225,000	$20,000 deduction allowed due to wage limits	~$4,400 saved (assuming 22% bracket) (The Tax Adviser)

Proper tax planning and consultation with a tax professional can help business owners navigate these rules and optimize their tax position. The QBI deduction remains one of the most significant recent tax changes benefiting pass-through entities.

Common Pitfalls and Compliance Risks

While pass-through taxation offers many benefits, business owners should be aware of common pitfalls:

• Misclassification of income or workers: S corporations must pay owner-employees a reasonable salary before dividends. Failure to do so may trigger IRS audits and penalties.

• Improper filing and documentation: Partnerships must file Form 1065 and issue Schedule K-1s accurately. Errors in the allocation of profits/losses can cause compliance issues.

• Incorrect LLC tax election: LLCs can choose to be taxed as partnerships, S corps, or C corps. Choosing the wrong election (or forgetting to file one) can create unintended tax liabilities.

• State-level tax variations: Some states do not conform to federal pass-through rules and may impose their own entity-level taxes. Business owners must monitor state-specific requirements.

• Poor record-keeping: Incomplete or inaccurate financial records increase the risk of IRS scrutiny and missed tax deductions.
