Key Takeaways
- LLCs and S Corps both offer pass-through taxation but differ in how employment taxes and profit distributions are handled.
- The primary tax benefit of S Corps is the ability to save on self-employment taxes by paying owner-shareholders a reasonable salary and distributing the remaining profits as dividends, which are not subject to self-employment tax.
- LLCs offer greater flexibility in ownership structure and fewer restrictions on who can be an owner.
- S Corp status requires meeting IRS eligibility criteria, including limits on the number and type of shareholders.
- Choosing between an LLC and an S Corp should consider factors like business size, expected profits, administrative complexity, and long-term growth plans.
LLC or S corp. tax advantages include the option of having the business income taxed on behalf of individual owners instead of the company.
LLC vs. S Corporation
New businesses should start out as an LLC. An LLC can choose S corp. status, but it's not possible to convert an S corp. to an LLC.
It's hardly sensible to convert a single-owner business into an S corp. for tax benefits. If the business' income is primarily made through sale of products, then structuring it as an S corp. might be beneficial. However, if the business' primary income is from the services provided by an individual, there is hardly any tax benefit in forming the company as an S corp.
An LLC is a separate legal entity from its owners, known as members. An LLC can have one or more members. The LLC structure is suited for small businesses and offers more flexibility than corporations. There are fewer formalities and legal obligations in terms of reporting and recordkeeping.
An S corporation is not a form of business. It only refers to special taxation status granted by the IRS. Though most of the single-member LLCs qualify for S corp. election, it must meet certain conditions. A business entity can't opt for S corp. status if:
- It's a foreign company.
- Any of the owners are nonresident aliens.
- Any of the owners are a corporation or a partnership firm.
You should elect the S corp. status only if it saves you money. Find out how much salary you would earn if you were to perform the same tasks in the capacity of an employee.
The salary you determine for owner-shareholders must pass IRS scrutiny. Once you've calculated the salary, ask yourself whether there would be any business profit left after deducting it. If there would be no profits, you wouldn't benefit from structuring your business as an S corp.
You can only save money through S corp. election if the business profits are higher than your salary. However, remember that your tax return would be little more complicated. If there are no other employees in the company, you must comply with the tax withholding requirements.
How are LLCs and S Corps Taxed?
For all businesses, tax is calculated based on the company's net income, which is computed by deducting all the allowable expenses from the gross income. Tax on an LLC's business income is paid by the owners individually on the basis of their ownership percentage.
For an S corporation, any profit remaining after deducting the working owners' salary is passed to individual owners for tax purposes. For example, if you own 50 percent of the company and receive a salary of $40,000, and the company makes a net profit of $60,000 (after deducting your salary), then you must include your salary of $40,000 and your profit share of $30,000 in your personal tax return.
S Corp vs. LLC: Tax Benefits
There is no separate federal tax classification for LLCs. Therefore, they are taxed either as a sole proprietorship, a partnership firm, a C corp., or an S corp. By default, a single-owner LLC is taxed as a sole proprietorship and a multi-owner LLC is taxed as a partnership firm. However, an LLC can opt to be treated as a C corp. or an S corp. for the purpose of taxation.
The major difference between taxation as a sole proprietorship, an LLC, and an S corp is the way you pay self-employment taxes (Medicare and social security taxes). Choosing S corp. status can help you save on these taxes.
An LLC owner reports the company's income and expenditure in his individual income tax return. He is considered self-employed and is required to pay self-employment taxes on the profits.
Just like self-employed individuals, employees are also subject to Medicare and social security taxes. However, half of the taxes owed by employees are paid by their employer.
An owner can be considered an employee if he is being paid a reasonable salary. The LLC gets to deduct the salary as business expenditure, and the owner-employee must include it as an income item in his personal tax return. Unlike sole proprietorships and LLCs, S corps pay Medicare and social security taxes only on owner-employee's salary.
Additional Tax Considerations for LLCs and S Corps
When evaluating the tax benefits of S Corp vs LLC, it’s important to look beyond basic pass-through taxation and consider several additional factors that could impact your tax savings and business operations:
1. Self-Employment Tax Savings with S Corps:
- LLC members must pay self-employment taxes (Social Security and Medicare) on all business profits.
- S Corp owners who are active in the business can receive a reasonable salary (subject to employment taxes) and take additional profits as distributions, which are not subject to self-employment tax.
- This structure can significantly reduce overall employment tax liability for profitable businesses where distributions exceed the reasonable salary.
2. Health Insurance Premium Deductions:
- S Corp owner-employees holding more than 2% of shares can deduct health insurance premiums, but they must report these premiums as wages on their W-2 forms.
- LLC owners may also deduct health insurance premiums, but the process is generally simpler because they are considered self-employed.
3. Retirement Plan Contributions:
- Both LLCs and S Corps can establish retirement plans like SEP IRAs or Solo 401(k)s.
- However, the way contributions are calculated may differ depending on whether you are classified as self-employed (LLC) or as an employee (S Corp), which could affect contribution limits.
4. Qualified Business Income (QBI) Deduction:
- Both S Corp shareholders and LLC members may be eligible for the 20% QBI deduction under Section 199A of the Tax Cuts and Jobs Act.
- This deduction applies to qualified pass-through income but may phase out at higher income levels for certain service-based businesses.
5. Tax Filing Complexity and Costs:
- S Corps face more complex tax filing requirements, including Form 1120S and issuing K-1 forms to shareholders.
- LLCs, depending on tax classification, may file simpler returns like Schedule C (for single-member LLCs) or Form 1065 (for multi-member LLCs).
6. State-Level Tax Considerations:
- Some states impose additional fees or franchise taxes on S Corps (e.g., California’s $800 minimum tax plus additional fees).
- LLCs may also face state-specific fees or annual reporting obligations, which vary widely by jurisdiction.
