What Is an LLC?
LLC is a new form of business structure suitable for small businesses. It offers operational flexibility, especially for the purpose of taxation. Its members can choose from several options to pay its taxes for maximum savings.
The IRS does not classify an LLC as a distinct taxation entity. Tax treatment of an LLC depends upon whether it has only one or multiple members and whether it chooses to file taxes as a different business structure.
A multi-member LLC can file its taxes either as a partnership firm or a corporation. Similarly, a single-member LLC can file its taxes as a sole proprietorship, where the business is not considered a different entity from its owner.
Forming a Limited Liability Company
Limited liability companies are formed and governed under state law. You must file articles of organization with the designated agency of the state where the headquarters of the company are located.
In most states, it's either the secretary of state or the Department of Commerce that looks after LLC affairs, including its formation. You must also pay a filing fee along with the formation documents.
The formation process is simple in most states. Usually, you just need to fill out a pre-printed form or follow a sample form.
If there is more than one member in your LLC, you should also prepare an operating agreement. This document should include items such as:
- Rights and responsibilities of the members
- Ownership percentage of each member
- Rules and procedures for managing the company
- Procedures for making major decisions
- Provisions and procedures for adding new members and
- The manner in which the LLC chooses to pay its taxes
After having formed an LLC, you may be required to pay yearly registration fees on an ongoing basis.
Tax Treatment of LLCs
Unless the operating agreement provides otherwise, an LLC is taxed in either one of the following two default manners:
- A single-member LLC pays its taxes as a sole proprietorship, wherein the owner files Schedule C for his personal tax return.
- A multiple-member LLC pays its taxes as a partnership firm and files an informational return in Form 1065.
In addition to the above default tax situations, an LLC can also elect to file its taxes as a corporation.
Key Components of Partnership LLC Taxes
Several elements determine how partnership LLC taxes are calculated and reported:
- Guaranteed Payments: These are payments made to members for services or capital contributions, even if the business operates at a loss. Guaranteed payments are reported as ordinary income and subject to self-employment tax.
- Profit and Loss Allocation: Unless stated otherwise in the operating agreement, profits and losses are divided based on each member’s ownership percentage.
- Self-Employment Taxes: Members in a partnership LLC generally pay self-employment taxes on their share of business income. However, they may reduce tax liability by electing S corporation status and paying themselves a reasonable salary.
- Estimated Tax Payments: Because LLCs don’t have withholding like traditional employment, members often need to make quarterly estimated tax payments to avoid penalties.
Maintaining thorough financial records and separating business and personal funds is essential to remain compliant with IRS rules and avoid tax penalties.
How Partnership LLC Taxes Work
A partnership LLC (multi-member LLC) is treated as a pass-through entity for federal income tax purposes. This means the business itself does not pay federal income tax; instead, profits and losses "pass through" to the members, who report them on their personal tax returns. The LLC must file Form 1065 (U.S. Return of Partnership Income) annually, which provides the IRS with information on the company’s income and expenses.
Each member receives a Schedule K-1 that details their share of profits, losses, and deductions. These figures are then reported on the individual’s Form 1040. Even if profits are not distributed, members must still pay taxes on their allocated share of income.
Members are also subject to self-employment tax (covering Social Security and Medicare) on their share of business income unless the LLC elects corporate taxation. To offset this, members can deduct ordinary and necessary business expenses, such as rent, utilities, and professional fees.
The Advantage of Electing to File Taxes as a Corporation
The income tax rate for individuals falling under higher income slabs is higher than the highest tax rate applicable to corporations. Thus, if your taxable income, after clubbing your share of company's income, becomes high, it would be beneficial to file a separate tax return for the LLC income.
The major advantage of filing your LLC taxes as a corporation is that you don't have to include the LLC's income on your personal tax return. This keeps your taxable income at the lower end of tax tables.
For example, if you are the only owner, and your company makes a taxable profit of $52,000 in a given year, then you must include the whole of this profit in your personal taxable income and pay taxes at a higher rate. However, if you choose to pay your LLC taxes as a corporation, you need not pay personal income tax on the business profit of the LLC.
When a Partnership LLC Should Elect Corporate Taxation
An LLC taxed as a partnership can choose to be taxed as a C corporation or S corporation by filing Form 8832 or Form 2553, respectively. This election may provide tax savings in specific cases:
- C Corporation Election: Profits are taxed at the corporate rate, and members receive dividends taxed at individual rates. While this introduces double taxation, it may lower overall taxes for higher-income members by capping corporate rates at 21%.
- S Corporation Election: Profits pass through to members like a partnership, but only the salaries paid to members are subject to self-employment tax. This can significantly reduce tax liability if structured correctly.
However, corporate elections add administrative requirements, such as running payroll and maintaining corporate records. Business owners should consult a tax advisor to determine if corporate taxation aligns with their income structure and goals.
LLC vs. Corporations: Tax Advantages
Favorable Tax Rates
The income tax rate for a limited liability company depends upon the taxable income of the owner. If the LLC income is high and the owner's income is less, the LLC can benefit from a lower tax rate compared to that of a corporation.
For instance, on a taxable income of $75,000, a corporation has to pay tax at the rate of 34 percent. On the other hand, an LLC can pass through its income to the owner and pay tax at a personal tax rate of 25 percent only, provided there is no other income included in the owner's tax return.
No Double Taxation
Unlike in case of corporations, an LLC is not subject to double taxation of income.
No Franchise Taxes
Some states require corporations to pay franchise taxes. However, there are no such taxes levied on an LLC.
Tax Compliance Tips for Partnership LLCs
To stay compliant with federal and state tax laws, partnership LLCs should:
- Keep Detailed Financial Records: Accurate bookkeeping helps ensure income, expenses, and distributions are correctly reported.
- Draft a Comprehensive Operating Agreement: Clearly define how profits, losses, and guaranteed payments are allocated among members.
- Separate Business and Personal Accounts: Maintain distinct financial accounts to avoid IRS reclassification issues.
- Make Timely Estimated Tax Payments: Avoid penalties by paying quarterly estimates for income and self-employment taxes.
- Stay Current on State Taxes: Many states impose additional filing or franchise taxes on LLCs.
- Consult Tax Professionals: A CPA or tax attorney can help structure the LLC to optimize deductions and minimize liabilities.
Keeping up with these practices helps partnership LLCs reduce the risk of audit, maintain compliance, and optimize their tax outcomes.
IRS Partnership Audit Rules for LLCs
Under the Bipartisan Budget Act of 2015, significant changes were made to how the IRS audits partnerships and multi-member LLCs. These rules apply to all tax years beginning after December 31, 2017.
- Centralized Audit Procedures: The IRS can now assess tax adjustments at the partnership level rather than individually through each partner’s return.
- Partnership Representative Requirement: Each LLC taxed as a partnership must designate a Partnership Representative (PR) on Form 1065. The PR has sole authority to act on behalf of the partnership during IRS audits.
- Election Out Option: Eligible partnerships (with 100 or fewer members, all being individuals or C corporations) can opt out of the centralized audit regime annually on their Form 1065.
Failure to designate a representative or respond to IRS notices can result in tax assessments being automatically applied at the partnership level, which may increase overall liability.
