How to File a Federal Income Tax Return for Your LLC (Even If You’re New)
How to File a Federal Income Tax Return for Your LLC (Even If You’re New)
Simple, beginner-friendly guidance for U.S. and non-U.S. entrepreneurs
Whether you’re a U.S. resident or a non-resident running a U.S. LLC, this guide will walk you through the essentials of filing your federal income tax return the right way—plus how to avoid costly mistakes and how iFiler can help.
🧾 First Things First: Know Your LLC’s Tax Classification
The IRS doesn’t have a “one-size-fits-all” form for LLCs. Instead, your LLC’s tax filing process depends on how it’s structured:
1. Single-Member LLC (U.S. Owner)
-
Default status: Disregarded Entity (taxed as a sole proprietorship)
-
Form to File: Schedule C (attached to your personal 1040 return)
-
You report profits/losses from your LLC on your personal income tax return.
2. Multi-Member LLC
-
Default status: Partnership
-
Form to File: Form 1065 (U.S. Return of Partnership Income)
-
Each partner receives a Schedule K-1 to report on their personal return.
3. LLC Electing Corporation Status
-
If your LLC chooses to be taxed as a C-Corporation:
-
File Form 1120
-
-
If electing S-Corporation status:
-
File Form 1120-S
-
Must also file Form 2553 to elect S-Corp status
-
💡 Not sure what your current tax classification is? iFiler can check your EIN and IRS records for you.
🌍 For Non-US Owners of a U.S. LLC
If you live outside the U.S. and own a U.S.-registered LLC, you still need to consider IRS rules carefully.
1. Single-Member LLC (Owned by Non-Resident Alien)
-
If you don’t have Effectively Connected Income (ECI) or U.S. source income, you may not owe taxes—but you still need to file.
-
File Form 5472 + Pro Forma 1120
-
Must file annually, even with zero income
2. Multi-Member LLC (With Foreign Members)
-
File Form 1065 + Schedule K-1s
-
Non-U.S. members may also need to file Form 1040-NR (if they receive ECI or U.S. income)
❗ Late or missed filings (especially Form 5472) can result in a $25,000 IRS penalty per year. iFiler helps foreign owners file accurately and on time.
📆 When Are Federal Tax Returns Due?
-
Individual (Schedule C) – Due: April 15
-
Form 1065 (Partnership) – Due: March 15
-
Form 1120 (C-Corp) – Due: April 15
-
Form 1120-S (S-Corp) – Due: March 15
-
Form 5472 + 1120 (foreign-owned LLC) – Due: April 15
✅ Extensions are available if filed before the due date, usually for 6 months.
🔁 What Do You Need Before Filing?
Here’s a simple checklist of what to gather:
-
EIN (Employer Identification Number)
-
Bank statements (to track income & expenses)
-
Expense receipts (office, software, marketing, etc.)
-
Invoices or sales records
-
Payroll data (if applicable)
-
Any prior year tax filings
-
Ownership structure documents
If you use accounting software like QuickBooks or Wave, exporting reports will make this process much easier.
⚠️ Common Mistakes First-Time LLC Owners Make
-
Filing late (or not at all)
-
Filing the wrong IRS form
-
Not keeping records of income/expenses
-
Failing to file Form 5472 as a non-U.S. owner
-
Assuming you don’t have to file because there’s “no profit”
You must file a return even if your LLC made no money. The IRS sees non-filing as worse than reporting a loss.
