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


Starting your first LLC is exciting—but when tax season comes around, things can get overwhelming. If you’re asking yourself:
“How do I file taxes for my LLC?”
You’re not alone.

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

  1. Filing late (or not at all)

  2. Filing the wrong IRS form

  3. Not keeping records of income/expenses

  4. Failing to file Form 5472 as a non-U.S. owner

  5. 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.

📚 Bonus: Should You File Yourself or Hire a Pro?

🧾 Wrap-Up: Key Takeaways

  • LLCs don’t file the same tax form—your filing depends on how your business is structured.

  • Even if your LLC made zero revenue, you likely still need to file something.

  • Missing deadlines or filing incorrectly can lead to fines.

  • iFiler makes U.S. tax compliance easy—especially for non-residents or e-commerce owners.
