【稅務規劃】穿透性征税Pass-Through如何影响您的个人税表？ | 智昕財稅諮詢｜LINCK CONSULTING INC.

对于 2026 年的中小企业主来说，您的公司架构不仅决定了您的法律责任，更直接决定了您个人税表（1040 表）上的最终数字。随着《大而美法案》（OBBBA）的实施，理解“穿透性征税（Pass-Through Taxation）”的原理已成为省税的关键。在 Linck Consulting，我们帮助您优化 LLC 与 S-Corp 的税务配置，确保您辛苦赚来的每一分钱都能更有效地留在口袋里。

什么是穿透性征税？

简单来说，穿透性征税意味着您的公司本身不缴纳联邦所得税。公司的盈利或亏损会像水流一样，“穿透”公司层面，直接流向您的个人税务账单。这意味着您只需要按个人所得税率缴税，避免了传统 C-Corp 面临的“公司缴一次、分红再缴一次”的双重征税。  

LLC 与 S-Corp 对您个人税单的不同影响

虽然两者都是穿透性实体，但在缴纳“自雇税（Self-Employment Tax）”时，它们对您个人钱包的影响大不相同：

1. LLC 的影响： 默认情况下，IRS 认为 LLC 的所有净利润都是您的劳动所得。这意味着在 2026 年，您的全部利润（最高达 $184,500）都需要缴纳 15.3% 的自雇税。  
2. S-Corp 的优化： S-Corp 允许您将收入分为“工资”和“分红”。您只需为工资缴纳社保和医保税，而剩下的“分红”部分则完全免除这 15.3% 的税负。对于年利润超过 10 万美元的企业，这在您的个人税表上往往体现为数千美元甚至更多的税务减免。  

OBBBA 法案下的新红利

2026 年的税法为您带来了两个重大利好：

1. 20% QBI 扣除永久化： 这相当于您的业务收入直接打了个“八折”后再计税。  
2. SALT 扣除限额提升至 $40,400： 如果您在加州或其他高税率州经营，您个人税表上的州税抵扣额度大幅提升，直接降低了您的联邦税负。  

为什么选择智昕財稅諮詢Linck Consulting？

“穿透”并不意味着“简单”。S-Corp 的合理薪资设定、QBI 的复杂计算以及新法案下的州税抵扣，都需要精确的会计建模。智昕財稅諮詢Linck 团队不仅为您提供专业的记账服务，更会站在 CFO 的高度，为您量身定制个人与公司的联动税务方案。

Pass-Through Taxation Explained: How S-Corps and LLCs Impact Your Personal Returns

At Linck Consulting, we believe that true financial clarity begins with understanding how your business structure dictates your personal tax liability. In 2026, the tax landscape has been reshaped by the One Big Beautiful Bill Act (OBBBA), making the distinction between LLC and S-Corp taxation more critical than ever. We specialize in helping entrepreneurs navigate these "pass-through" rules to optimize their 1040 returns while ensuring full compliance with the latest IRS standards.

What is Pass-Through Taxation for Small Businesses?

Pass-through taxation is a system where the business entity itself does not pay federal income taxes; instead, the company's profits and losses "pass through" directly to the owners' personal tax returns. Under this framework, the income is taxed only once at the individual level, avoiding the double taxation typically associated with C-Corporations.

For LLCs and S-Corps, this means your share of business net income is reported on Schedule E of your Form 1040. However, while the income tax treatment is similar, the payroll tax implications differ significantly. Understanding this "pass-through" mechanism is the first step in determining how much of your business revenue actually reaches your personal bank account after the IRS takes its share.

How Do LLCs and S-Corps Impact Personal Tax Returns Differently?

The primary impact on your personal tax return involves how self-employment (SE) taxes are calculated and reported. In a standard LLC, the IRS views the owner as a self-employed individual, meaning the entire net profit is subject to the 15.3% SE tax (Social Security and Medicare) on your personal return, up to the 2026 wage base of $184,500.

Conversely, an S-Corp election allows you to bifurcate your income into two "buckets":

1. W-2 Salary: Subject to standard payroll taxes.
2. Shareholder Distributions: Reported as pass-through income that is exempt from the 15.3% SE tax.

By strategically setting a "reasonable salary," S-Corp owners can significantly lower their total tax bill on Form 1040. For a business netting $150,000, an S-Corp owner might save over $10,000 in SE taxes compared to a default LLC owner, provided their salary meets the market-rate standards for their role.

What are the 2026 Pass-Through Tax Benefits Under the OBBBA?

The OBBBA has solidified several key advantages for pass-through owners that directly impact personal returns. Most notably, the 20% Qualified Business Income (QBI) deduction has been made permanent. This allows eligible owners to deduct up to 20% of their "qualified" business income from their taxable income, effectively lowering their top effective tax rate.

Additionally, the OBBBA adjusted the SALT (State and Local Tax) deduction cap to $40,400. For business owners in high-tax states, this quadrupling of the previous limit allows for a much larger portion of state-level business taxes to be deducted on Schedule A of the personal return. At Linck Consulting, we integrate these legislative updates into your year-round strategy to ensure your pass-through entity is serving your personal financial goals.
