Should a sole proprietorship with annual revenue of 5 million convert to a limited liability company? Don’t just look at the tax rate.
Published: August 25, 2026

For a sole proprietorship, reaching an annual turnover of 5 million is a delicate tipping point. Many people’s first reaction is, ”Convert to a limited liability company—the corporate income tax rate is only 25%, which is lower than the 35% rate for sole proprietorships.” But the decision to convert shouldn’t be based solely on tax rates—getting this step wrong could result in paying an extra tax or missing a potential pitfall.

I. First, Let’s Examine the Tax Burden Logic for the Two Types of Entities

Common Methods of Tax CollectionMore options for assessed taxation; lower overall tax burdenPrimarily based on audit-based taxation

II. Why ”Don’t Just Look at the Tax Rate”

The highest tax rate for sole proprietorships is 35%, while the corporate income tax rate for limited liability companies is 25%—on the surface, the corporate rate appears lower. However, sole proprietorships are not subject to corporate income tax or dividend tax, and in many regions, they are taxed under a fixed-rate assessment system, resulting in an effective tax rate that is often as low as 1%–3%. When you compare the two after factoring in both taxes, a limited liability company actually ends up with less take-home pay.

In addition to tax rates, there are four other things to consider:

- Responsibility: A sole proprietor isUnlimited liability, business debts can affect personal and family assets; a limited liability company islimited liability, limited to the amount of the capital contribution. · Admission: Many platforms explicitly require this for onboarding, bidding, partnerships with brands, and eligibility to issue special invoices.Limited Liability Companies and even general taxpayers。· Funding: Limited liability companies can raise equity capital and have easier access to loans; sole proprietorships can generally only secure loans through collateral. · Exit: Limited liability companies can transfer shares or exit at a premium; sole proprietorships can only be dissolved and liquidated.

III. The “Accounting Bomb”: Who Ends Up with More When Profits Are the Same?

Assuming annual revenue of 5 million and a profit margin of approximately 20% (annual profit of 1 million):

Main BodyTax burden measurementThe Boss Is Ours
Self-employed individual (fixed-rate taxation; total approximately 2%)About 20,000About 980,000
Self-employed individual (audited accounts, profit of 1 million)Business income tax of approximately 280,000About 720,000
corporationCorporate tax: 250,000 + Dividends: 20% (150,000)About 600,000

For the same profit, a limited liability company takes home less than a sole proprietor. 120,000–380,000.”The idea that ”converting to a corporate structure lowers taxes' is an illusion."

IV. The 3 Most Common Pitfalls

- Looking Only at Nominal Tax Rates: I forgot that limited liability companies also have to deal with the 20% dividend tax. · Excluding business licensing requirements: Only when I wanted to take on large orders from the platform or bid on projects did I realize that my sole proprietorship didn’t meet the eligibility requirements. · Disregarding Unlimited Liability: Once a business has high cash flow, significant assets, and employees, the unlimited liability of a sole proprietorship becomes a real risk.

V. A 4-Step Approach: How to Decide Whether to Switch

① View Liability Exposure: Large asset base, significant external debt, and employees → Tend to opt for a limited liability company to isolate risks. ② Check the admission requirements: Determine what type of entity the target customers/platform require, and align on that before making a decision. ③ Net take-home pay: Take into account tax assessments, dividend distributions, and corporate taxes—not just the nominal tax rate. ④ Compliance Conversion: Settle tax obligations, deregister your sole proprietorship, establish a new company, and ensure a seamless transition for social security and tax forms—don’t leave any gaps.

Remember this: Whether or not to proceed depends on responsibility, eligibility, and take-home pay—not on the nominal tax rate.
