S corp vs LLC tax benefits for small businesses
The choice between forming your small business as an S corporation (S corp) or a limited liability company (LLC) is an important one that can significantly impact your taxes. Both entity types provide liability protection, but they are taxed quite differently. In this comprehensive guide, we'll explore the tax benefits of S corps and LLCs to help you determine which structure is most advantageous for your small business.
As a small business owner, one of the most critical decisions you'll make is choosing the right legal entity for your company. The two most popular options are S corporations and limited liability companies. While both provide limited liability protection, meaning your personal assets are shielded from business debts and lawsuits, they have distinct differences in how they are taxed.
The entity you select can have major implications for your bottom line, as it affects your tax obligations, your ability to raise capital, and the overall financial management of your company. In this article, we'll do a deep dive comparing the tax benefits of S corps and LLCs so you can make an informed choice for your small business.
1. Understanding S Corporations
What is an S Corporation?
An S corporation, also known as an S corp, is a type of corporate entity recognized under the Internal Revenue Code. It is formed by making an S corp election with the IRS, which allows the company to pass corporate income, losses, deductions, and credits through to its shareholders for federal tax purposes.
To be eligible to elect S corp status, the company must meet certain requirements:
- It must be a domestic corporation
- It can have no more than 100 shareholders
- Shareholders must be individuals, certain trusts, and estates; partnerships, corporations and non-resident aliens cannot hold shares
- It can have only one class of stock
- It must use a calendar year as its fiscal year
S Corporation Taxation
An S corp is a pass-through entity for tax purposes. This means that the business itself does not pay federal income tax. Instead, the company's income and losses are divided among and passed through to its shareholders, who must then report their share of the profit or loss on their individual income tax returns. Therefore, income is taxed at the shareholder level, not at the corporate level.
However, most states require S corps to pay a franchise tax or similar fees. And if the S corp was previously a C corporation, it may face built-in gains tax or passive income tax in certain situations.
S Corporation Tax Benefits
One of the main tax advantages of an S corp is that it provides a way to reduce self-employment (SE) taxes, which are a combination of Social Security and Medicare taxes. In an S corp, only the wages paid to a shareholder-employee are subject to employment taxes. The remaining income can be paid as a distribution, which is taxed at a lower rate if it meets certain criteria.
Here's how it typically works:
- The S corp pays its employee-shareholders a reasonable salary for their work. This salary is subject to payroll taxes (Social Security and Medicare taxes, also known as FICA taxes).
- Any remaining profit in the S corp can be distributed to the shareholders as dividends, which are not subject to self-employment taxes. However, dividends may be subject to income tax at the shareholder level.
This differs from a sole proprietorship or partnership, where all of the business's net earnings are subject to self-employment tax. By characterizing a portion of the income as salary and a portion as a distribution, you can potentially reduce your overall tax burden.
It's important to note that the IRS requires that S corp owners pay themselves a reasonable salary based on their job duties, skills, and experience. The salary should be comparable to what other businesses pay for similar services. If the IRS determines that a shareholder-employee's salary is unreasonably low, it may recharacterize some of the distributions as wages and impose penalties.
2. Understanding Limited Liability Companies (LLCs)
What is a Limited Liability Company?
A limited liability company (LLC) is a business structure that offers personal liability protection and a flexible management structure. Like S corps, LLCs provide limited liability protection, meaning that the personal assets of the owners (known as members) are typically shielded from business debts and liabilities.
However, LLCs have fewer restrictions than S corps. There is no limit to the number of members an LLC can have, and members can include individuals, corporations, other LLCs, and foreign entities. Also, LLCs are allowed to have different classes of ownership interests.
LLC Taxation
By default, an LLC with one member is taxed as a sole proprietorship, while an LLC with multiple members is taxed as a partnership. This means that the LLC itself does not pay federal income taxes. Instead, the profits and losses pass through to the members' personal tax returns. The members must pay self-employment taxes (Social Security and Medicare taxes) on their share of the LLC's net earnings.
However, an LLC can elect to be taxed as an S corp or C corp for federal tax purposes. If it chooses S corp status, it will be taxed according to S corp tax rules (see above). If it elects C corp status, the LLC will pay corporate income tax, and any dividends will be taxed at the individual shareholder level.
LLC Tax Benefits
The primary tax benefit of an LLC is the flexibility it provides in terms of how it is taxed. As mentioned, an LLC can choose to be taxed as a sole proprietorship (for single-member LLCs), partnership, S corp, or C corp.
If an LLC elects S corp status, it can take advantage of the same self-employment tax savings as a regular S corp. The members can be paid a reasonable salary, with the remaining profits distributed as dividends, which are not subject to self-employment taxes.
Another potential benefit is the flexibility to allocate profits and losses differently than ownership percentages. For instance, an LLC taxed as a partnership can allocate a larger share of profits to a member who contributed more capital or sweat equity. However, the IRS requires that profit and loss allocations have "substantial economic effect," meaning they must reflect the members' actual economic interests in the LLC.
3. Key Differences in Taxation: S Corp vs LLC
Pass-Through Taxation
Both S corps and LLCs (taxed as sole proprietorships or partnerships) are pass-through entities, meaning the business itself does not pay federal income tax. Instead, business income "passes through" to the owners' personal tax returns. The owners pay tax on their share of the business's profits at their individual income tax rates.
This can be beneficial because it avoids the "double taxation" that happens with C corporations. In a C corp, the business pays corporate income tax on its profits, and then the shareholders pay personal income tax on any dividends they receive from the company. With pass-through taxation, business income is only taxed once.
Self-Employment Taxes
A key difference between S corps and LLCs taxed as sole proprietorships or partnerships is how self-employment (SE) taxes are handled. SE taxes refer to Social Security and Medicare taxes.
In an LLC taxed as a sole proprietorship or partnership, all of the business's net earnings are subject to SE taxes. The members must pay these taxes on their share of the profits, even if they leave the money in the business.
In contrast, only the salaries paid to S corp shareholder-employees are subject to employment taxes (equivalent to SE taxes). The remaining profits can be paid out as distributions, which are not subject to employment taxes. This can result in significant tax savings for S corp owners.
However, the IRS requires that S corp owners be paid a "reasonable salary" based on their roles and the market rate for their services. If the salary is deemed too low, the IRS may recharacterize some of the distributions as wages and impose penalties.
Flexibility in Allocating Income and Losses
An LLC taxed as a partnership has more flexibility in allocating profits and losses among its members. Profits and losses can be allocated differently than ownership percentages, as long as the allocations have "substantial economic effect." This means they must reflect the members' actual economic interests in the LLC.
For example, if one member contributed more capital or labor to the LLC, they could be allocated a larger share of the profits. Or if a member is in a higher tax bracket, they could be allocated a larger share of the losses to offset their other income.
S corps, on the other hand, must allocate profits and losses strictly according to stock ownership. If one shareholder owns 60% of the shares, they must receive 60% of the profits or losses.
Ownership Restrictions
S corps have more restrictions on ownership than LLCs. An S corp can have no more than 100 shareholders, and all shareholders must be U.S. citizens or resident aliens. Shareholders can only be individuals, certain trusts, and estates. Partnerships, corporations, and non-resident aliens cannot hold S corp stock.
There are also restrictions on the classes of stock an S corp can have. It can only have one class of stock, although differences in voting rights are allowed.
LLCs have no restrictions on the number or type of members they can have. Members can include individuals, partnerships, corporations, other LLCs, trusts, and foreign entities. LLCs can also have different classes of membership interests with different rights to distributions and management participation.
4. Scenarios Where an S Corp May Provide Better Tax Benefits
When owner compensation is below a certain threshold
The primary tax advantage of an S corp is the ability to save on self-employment (SE) taxes. If the business owner's compensation is below the Social Security wage base (which is $160,200 for 2023), they may benefit from electing S corp status.
Here's an example: Let's say a small business has $100,000 in net earnings. If it's taxed as a sole proprietorship or partnership, the entire $100,000 would be subject to SE taxes (currently 15.3%, which consists of 12.4% for Social Security and 2.9% for Medicare).
But if the business is an S corp, and the owner is paid a reasonable salary of $60,000, only that $60,000 is subject to employment taxes. The remaining $40,000 can be paid as a distribution, which is not subject to SE taxes. This could result in a tax savings of over $6,000.
Businesses with steady profits that can be paid out as distributions
S corp status is most beneficial for businesses that have steady, predictable profits that can be paid out to owners as distributions. This is because distributions are not subject to SE taxes, whereas all of the net earnings of a sole proprietorship or partnership are subject to these taxes.
If a business has inconsistent or unpredictable profits, or if it needs to reinvest most of its earnings back into the business, the tax benefits of an S corp may be limited. The owner would still need to pay themselves a reasonable salary, which would be subject to employment taxes, but there may be little left over to distribute as dividends.
5. Scenarios Where an LLC May Provide Better Tax Benefits
Businesses with flow-through income or losses
An LLC taxed as a partnership may be advantageous for businesses that want to allocate profits and losses differently than ownership percentages. For instance, if one member contributed more capital or sweat equity, they could be allocated a larger share of the profits. Or if a member is in a higher tax bracket, they could be allocated a larger share of the losses to offset their other income.
S corps, on the other hand, must allocate profits and losses strictly according to stock ownership percentages.
Real estate holding companies
LLCs are a popular choice for real estate businesses because they offer liability protection and tax advantages. When an LLC holds real estate, the property can be distributed to the members without triggering a taxable event. This can be useful for estate planning or when a member wants to leave the LLC.
Also, if the real estate generates losses (for example, from depreciation deductions), those losses can flow through to the members' personal tax returns to offset other income. However, passive activity loss rules may limit the use of these losses.
Companies with foreign owners
An LLC may be a better choice than an S corp if the company has foreign owners. That's because S corps are restricted to U.S. citizen and resident alien shareholders. LLCs have no such restriction - they can have foreign individuals or entities as members.
However, a foreign-owned LLC may need to file additional IRS forms and may be subject to different tax treatment than a domestically-owned LLC. It's important to consult with a tax professional to understand the implications.
6. Other Factors to Consider
Formation and ongoing compliance requirements
S corps and LLCs have different formation and ongoing compliance requirements. Generally, S corps have more extensive requirements, which can result in higher administrative costs.
To form an S corp, you must first incorporate the business by filing articles of incorporation with your state, and then file Form 2553 with the IRS to elect S corp status. S corps must also observe corporate formalities, such as holding annual meetings, maintaining meeting minutes, and following bylaws.
LLCs are typically easier and less expensive to form. You file articles of organization with your state, and in most states, that's the only required document. LLCs have fewer ongoing formalities, although it's recommended to have an operating agreement that outlines the members' rights and responsibilities.
Both S corps and LLCs must obtain necessary licenses and permits, and file annual reports with their state. They also must file federal and state tax returns and payroll tax returns if they have employees.
Ability to raise capital
If you plan to seek outside investment for your business, the entity you choose can impact your ability to raise capital.
Corporations, including S corps, can issue stock to attract investors. This can make it easier to raise large amounts of capital. However, S corps are limited to 100 shareholders, which can limit their growth potential.
LLCs typically raise capital by admitting new members, who contribute capital in exchange for a membership interest. However, some investors may prefer the familiarity and standardized procedures of investing in a corporation.
Exit strategy and future plans for the business
Your long-term plans for your business can also influence whether an S corp or LLC is the better choice.
If you plan to eventually go public or be acquired by a public company, an S corp may not be the best choice. That's because S corps can only have up to 100 shareholders, and all must be U.S. citizens or residents. To go public or be acquired, you'd need to convert to a C corp, which can have significant tax consequences.
If you plan to pass the business down to family members, an LLC may offer more flexibility. You can gift or bequeath LLC membership interests without triggering a taxable event. With an S corp, transferring shares may require complex valuation and may trigger taxes.
7. How to Decide Between an S Corp and LLC
Deciding between an S corp and an LLC requires careful consideration of your business's specific circumstances, including its profit level, growth plans, and ownership structure.
Here are some general guidelines:
- If your business consistently generates more than $60,000 in net income per owner, an S corp may provide significant self-employment tax savings.
- If your business has variable income or losses that you want to allocate differently than ownership percentages, an LLC taxed as a partnership may be advantageous.
- If you plan to seek outside investors, an S corp may be preferable because of its ability to issue stock. However, if you plan to have more than 100 shareholders or foreign investors, an LLC may be better.
- If you want the simplicity and flexibility of an LLC but also want to save on self-employment taxes, you can form an LLC and elect S corp tax treatment.
Ultimately, the decision should be made with the guidance of a tax professional and attorney who can assess your unique situation and help you weigh the pros and cons of each entity type.
Choosing between an S corp and an LLC is a critical decision that can significantly impact your small business's taxes and operations. While both offer liability protection, they differ in how they are owned, managed, and taxed.
S corps can provide substantial savings on self-employment taxes, but they have more ownership restrictions and compliance requirements. LLCs offer more flexibility in management and profit allocation but may result in higher self-employment taxes.
The best choice for your business will depend on a variety of factors, including your business's income level, plans for growth and investment, and long-term goals. It's essential to consult with a knowledgeable tax advisor and attorney to determine the optimal structure for your unique circumstances.
Regardless of which entity you choose, careful tax planning is crucial to maximizing your tax savings and ensuring compliance with all regulations. By understanding the tax implications of S corps and LLCs, you can make informed decisions that benefit your business's bottom line.
