Key takeaways:
- LLCs offer flexible taxation: default pass-through (sole proprietorship/partnership) or elected corporate (S-corp/C-corp) status.
- Depending on the LLC’s status, your tax requirements and form submissions will change.
- Accurate records (income, expenses, statements, past returns) are vital for tax filing and deductions.

What is an LLC?
A Limited Liability Company (LLC) is a business structure that protects its owners, known as members, from personal liability for business debts and legal claims. If the business is sued or takes on debt, only the LLC’s assets are at risk. Personal assets, such as your home, savings, or vehicle, are generally protected.
LLCs are especially popular with small business owners because they offer liability protection without the administrative burden of a corporation. There is no requirement for a board of directors, and ongoing paperwork is typically minimal.
Think of an LLC as a legal barrier between your business and your personal finances. For example, if you own a bakery and a customer files a lawsuit related to a product you sold, the claim is limited to the business itself rather than your personal assets.
Starting an LLC typically involves state filing fees that range from about $50 to several hundred dollars, depending on where you form your business, along with optional costs such as registered agent services, operating agreement preparation, and business licenses or permits. Ongoing expenses may also include annual report fees, state franchise taxes, and professional services if you use legal or accounting support.

How are LLCs taxed?
LLCs are taxed based on their ownership structure and whether the owners elect a specific tax classification. By default, an LLC is treated as a pass-through entity. This means the business itself does not pay federal income tax. Instead, profits and losses pass through to the owners, who report them on their personal tax returns.
This structure avoids double taxation, which applies to C corporations where income is taxed at both the business and owner level.
Default LLC tax classifications
The Internal Revenue Service (IRS), the federal agency responsible for tax collection and enforcement, assigns LLCs one of two default tax classifications.
Single-member LLCs
An LLC with one owner is treated as a sole proprietorship for tax purposes. Business income and expenses are reported on Schedule C, which is filed with the owner’s personal Form 1040. Because taxes are not withheld, the owner must also pay self-employment taxes to cover Social Security and Medicare, currently totaling 15.3 percent—with a caveat. Social Security tax contributions change year by year, and in 2026, the taxable wage limit increases yearly and is $184,500 in 2026. Self‑employment Social Security tax remains 12.4%. As for Medicare, it accounts for 2.9% of tax contributions, but if you make more than $200,000 in net earnings, you have to pay an additional 0.9% to Medicare.
Multi-member LLCs
An LLC with two or more owners is taxed as a partnership. The business files Form 1065 to report total income and expenses, but it does not pay income tax itself. Each owner receives a Schedule K-1 showing their share of profits or losses, which they report on their personal return.
In both cases, the LLC does not pay federal income tax directly. The tax responsibility falls on the owners, and how it’s reported depends on the number of members.
Electing corporate taxation for an LLC
LLCs can also elect to be taxed as a corporation if it better aligns with their financial goals.
S corporation election
By filing Form 2553, an LLC can elect S corporation status. This allows owners to take part of their income as a salary, which is subject to payroll taxes, and the remainder as distributions, which are not subject to self-employment tax. This can be beneficial once profits are consistently high enough that the self-employment tax savings outweigh added payroll and filing complexity—many advisors start evaluating it around the mid–five figures, but it depends.
C corporation election
By filing Form 8832, an LLC can elect to be taxed as a C corporation. The business pays corporate income tax using Form 1120, and owners pay taxes again on dividends. This structure is typically used by businesses planning to reinvest profits or raise outside capital.
Which tax election is best for your LLC?
- Stick with the default classification if your LLC is small, has modest profits, or you prefer a straightforward filing process.
- Consider an S corporation election if your business generates steady profits and you want to reduce self-employment taxes.
- Choose C corporation taxation if you plan to scale aggressively, reinvest earnings, or raise capital from investors.
Step-by-step guide to filing business taxes for an LLC
Filing taxes for an LLC might seem daunting at first glance. But we’ll break it down to make it manageable and help you learn the process. Here’s what you need to do:
- Gather the necessary documents
- Identify the correct tax forms
- Calculate and pay the estimates
- Maximize deductions and tax credits
- File your taxes
Step 1: Gather the necessary documents
Organizing your financial records before filing makes tax season smoother and reduces errors. It also helps you identify deductions and maintain a clear separation between personal and business finances.
Key documents include:
- Income statements, such as a profit and loss statement
- Expense records, including receipts, invoices, and bank statements
- Estimated tax payment records
- Payroll records, including W-2 for employees and 1099-NEC for independent contractors.
- A year-end balance sheet
- Business bank statements
- Prior-year tax returns
Keeping personal and business finances separate is critical for both tax accuracy and liability protection.
Step 2: Identify the correct tax forms
The forms you file depend on how your LLC is taxed.
- Single-member LLCs: Schedule C with Form 1040 and Schedule SE
- Multi-member LLCs: Form 1065 and Schedule K-1 for each owner
- S corporations: Form 1120-S and Schedule K-1
- C corporations: Form 1120, with dividends reported on personal returns if applicable
Filing the correct forms ensures compliance and helps avoid unnecessary IRS scrutiny.
Step 3: Calculate and pay estimated taxes
If you expect to owe $1,000 or more in taxes, the IRS requires quarterly estimated payments. Since no taxes are automatically withheld, you’ll need to estimate your annual income, apply the appropriate tax rates, and include self-employment taxes if applicable.
Pay by the IRS quarterly due dates (typically April 15, June 15, September 15, and January 15), noting they may shift slightly for weekends or holidays. Paying on time helps you avoid penalties and large year-end tax bills.
Payments can be made online through the IRS Electronic Federal Tax Payment System or by mailing Form 1040-ES.
Step 4: Maximize deductions and tax credits
Deductions and credits can significantly lower your taxable income, but only if you keep accurate records. Common deductions for LLCs include:
- Home office expenses
- Self-employment tax deductions
- Business expenses such as marketing, insurance, and professional services
- Retirement plan contributions, including SEP IRAs and solo 401(k)s
Tax credits may also apply, depending on your business activities, and can directly reduce the amount you owe.
Step 5: File your taxes
Once everything is calculated and reviewed, file your return using IRS e-file, tax software, or a CPA. For more complex LLCs, professional support can provide peace of mind and help uncover additional savings.
Common mistakes first-time LLC owners make and how to avoid them
Starting an LLC is a smart move, but many first-time owners run into avoidable issues that can create legal, tax, or financial problems down the line. Being aware of these mistakes early helps you protect your business and stay compliant. Here are some common mistakes you might encounter:
- Mixing business and personal finances
- Choosing the wrong tax classification
- Skipping a written operating agreement
- Overlooking state-level compliance requirements
- Assuming an LLC eliminates the need for insurance
- Poor record-keeping beyond tax documents
- Trying to manage everything alone
- Missing filing deadlines
Mistake 1: Mixing business and personal finances
Using personal accounts for business expenses blurs financial records, complicates tax filing, and can weaken your liability protection if your business is ever challenged legally.
How to avoid it:
Open a dedicated business checking account and use a business credit card exclusively for LLC expenses. This creates a clear paper trail and simplifies bookkeeping.
Mistake 2: Choosing the wrong tax classification
Many LLC owners default to the IRS-assigned tax status without evaluating whether another option could reduce taxes or better support long-term goals.
How to avoid it:
Review your tax classification with a tax professional, especially as profits grow. An S corporation or C corporation election may be more efficient depending on income and plans.
Mistake 3: Skipping a written operating agreement
Without a written operating agreement, your LLC defaults to state rules that may not reflect how you actually want the business to operate. This can create issues with ownership, decision-making, or legal disputes.
How to avoid it:
Create an operating agreement even if you are the sole owner. It documents ownership, responsibilities, and financial arrangements and reinforces your LLC’s legitimacy.
Mistake 4: Overlooking state-level compliance requirements
Beyond federal taxes, states often impose annual reports, franchise taxes, or other filings. Failure to meet these obligations can result in penalties or loss of good standing.
How to avoid it:
Research your state’s LLC requirements and track deadlines in a compliance calendar. Consider using a registered agent or a compliance service to send reminders.
Mistake 5: Assuming an LLC eliminates the need for insurance
While an LLC provides liability protection, it does not cover all risks. Certain claims, losses, or lawsuits can still impact the business and, in some cases, the owner.
How to avoid it:
Obtain business insurance tailored to your industry, such as general liability, professional liability, or property coverage, to protect against common risks.
Mistake 6: Poor record-keeping beyond tax documents
Focusing only on tax records while neglecting contracts, decisions, and agreements can lead to disputes, audit challenges, or operational confusion.
How to avoid it:
Maintain organized records of major business decisions, contracts, purchases, and correspondence using digital storage or accounting software.
Mistake 7: Trying to manage everything alone
Handling taxes, legal compliance, and financial planning without professional support often leads to errors and missed opportunities.
How to avoid it:
Build a small network of trusted advisors, such as an accountant, attorney, and insurance agent, who understand small business needs.
Mistake 8: Missing filing deadlines
Late tax filings, annual reports, or required payments can trigger penalties, interest, or even administrative dissolution of your LLC.
How to avoid it:
Create a business calendar with all federal and state deadlines. Set reminders well in advance or use accounting software that automatically tracks due dates.
