If you own a limited liability company (LLC), being able to file your business’s taxes is a crucial financial skill. While LLCs have flexible tax treatment, which means they have more options available to them, it also means they have more decisions to make. This guide will help you tackle every option clearly and straightforwardly.
1. What Does It Mean to File Taxes for an LLC?
By default, LLCs are considered pass-through entities. This means that the business will not pay federal income taxes directly, and the business’s profits and losses pass through to the owners. This is reported by the owners on their personal income tax returns. However, depending on the structure of your LLC and the elections you make with the IRS, your filing situation can look vastly different.
2. How Is Your LLC Taxed? (Choosing the Right Tax Classification)
Before filing anything, you should understand how your LLC is classified by the IRS:
| LLC Type | Default IRS Treatment |
| Single-Member LLC | Sole proprietorship (disregarded entity) |
| Multi-Member LLC | Partnership |
| LLC with S Corp election | S Corporation |
| LLC with C Corp election | C Corporation |
You can update your classification by submitting Form 8832 (Entity Classification Election) or Form 2553 (S Corp election). Each classification has unique tax responsibilities, associated deadlines, and required forms.
3. How to File Taxes for a Single-Member LLC
Single-member LLCs are considered disregarded entities by the IRS. This means you report everything on:
- Schedule C (Profit or Loss from Business). This is filed with your Form 1040.
- Schedule SE: This is the form for self-employment tax (15.3% on your net earnings).
Please note that if you have a corporate election, you will have a separate federal business return. You should also keep careful records for the entire year for all revenue and expenses you want to deduct.
4. How to File Taxes for a Multi-Member LLC
For a multi-member LLC, by default, they are considered partnerships. This means that you are required to report the following:
- Form 1065 (U.S. Return of Partnership Income) is an informational return.
- You will also have to give each member a Schedule K-1, which will detail each member’s share of partnership income, along with the deductions and credits.
- Then each member must report the K-1 information on their personal Form 1040.
Important: Form 1065 is due March 15, not April 15. If you fail to submit your form, there is a possibility of incurring a penalty, even if there is no tax due.
5. How to File Taxes for an LLC Taxed as an S Corporation
When an LLC chooses to be taxed as an S Corporation, the owner must complete the following steps:
- Submit Form 1120-S (U.S. Income Tax Return for S Corporations)
- Submit a Schedule K-1 for every shareholder
- Pay a reasonable salary to yourself as a W-2 employee of the LLC
- Run payroll and file payroll tax documents every quarter
While this option could be fiscally beneficial for self-employment tax purposes for profitable businesses, it does also mean taking on more business administration work.
6. How to File Taxes for an LLC Taxed as a C Corporation
When an LLC is taxed as a C Corporation, the owner must complete Form 1120. Unlike the other business structures, C Corporations tax the income at the entity level (which is a flat 21% as of the date of this article), and the income is also taxed at the owner level, which is referred to as double taxation. This business structure is less common for small LLCs; however, it is beneficial for businesses that want to have outside investors.
7. Federal vs. State Requirements When Filing LLC Taxes
Federal filing isn’t all-encompassing. Requirements on the state level differ significantly:
- Some states have no income tax, such as Wyoming and Nevada.
- Some states have a minimum franchise or LLC tax; California charges $800/year, no matter the profit.
- Some states require a separate state business return.
- Some states do not follow the federal classification, while others do.
Check your state’s department of revenue or reach out to a local tax professional.
8. What Tax Forms Do You Need to File LLC Taxes?
Depending on your LLC type, refer to the following:
| LLC Classification | Primary Federal Form |
| Single-Member LLC | Schedule C + Form 1040 |
| Multi-Member LLC | Form 1065 + K-1s |
| S Corporation | Form 1120-S + K-1s |
| C Corporation | Form 1120 |
Some additional forms that may be required include Schedule SE, Form 941 (for payroll taxes), and Form 8829 (for home office deduction).
9. Estimated Taxes for LLC Owners: What You Must Pay Throughout the Year
Because most LLC owners do not have taxes withheld from their income, the IRS requires them to make quarterly estimated tax payments. These payments are due as follows:
- Q1 Payment: April 15
- Q2 Payment: June 16
- Q3 Payment: September 15
- Q4 Payment: January 15 (of the following year)
Estimated payments are calculated and submitted on Form 1040-ES. Even if you pay your taxes at the end of the year, you can still owe penalties if you underpay during the year.
10. LLC Tax Deductions You Shouldn’t Miss
Maximizing tax deductions is one of the most significant benefits of knowing how to file taxes for LLC businesses. Some common write-offs include:
- Home office costs (Form 8829)
- Business vehicle mileage (67 cents/mile in 2024)
- Health insurance premiums for self-employed owners
- Startup and organizational costs
- Software, subscriptions, and tools
- Professional services (legal, accounting)
- Education and training directly related to your business
- Retirement contributions (SEP-IRA, Solo 401k)
Don’t leave money on the table. Good bookkeeping makes claiming deductions much easier.
11. Common Mistakes to Avoid When Filing LLC Taxes
It’s easy to make mistakes. Here are some to watch out for:
- Not separating personal and business finances, you should have a separate business bank account.
- Ignoring state filings, federal compliance is just one part.
- Misclassifying employees’ tax laws for employees and independent contractors is different.
- Not keeping receipts and other records, audits can go back 3–6 years.
- Filing incorrect forms, especially after an S Corp or C Corp election.
12. Important LLC Tax Deadlines to Remember
| Due Date | What’s Due |
| March 15 | Partnership returns (Form 1065) and S Corp returns (Form 1120-S) |
| March 31 | 1099-NEC / 1099-MISC (electronic filing) |
| April 15 | C Corp returns (Form 1120) and sole proprietorship/single-member LLC returns (Form 1040) |
| April 15, June 16, Sept 15, Jan 15 | Quarterly estimated tax payments |
Extensions are permitted, but you must pay taxes owed by the original due date. An extension gives you more time to file, not more time to pay.
13. Should You File LLC Taxes Yourself or Hire a Professional?
It all depends on your individual situation.
If you have a single-member LLC with straightforward income streams, it should be pretty manageable to file taxes on your own, especially with the help of a reliable program like EasyFiling, as long as you keep your finances organized and easy to follow.
It might be time to hire a CPA or tax professional if your LLC has multiple members, involves payroll, or has made an S or C Corporation election. A professional is also worth considering if your deductions are complex, your income is high, you’ve received IRS notices, or you have tax obligations across multiple states. Good accountants often end up being worth the money because they help you save on taxes and avoid penalties.
