Do LLCs With No Income Need to File? The “Dormant” Partnership Penalty Guide (2025)

One of the most dangerous misconceptions in the US tax world is the belief that “No income equals no paperwork.” If you formed an LLC in 2024 or 2025 but haven’t made a dime, you might assume you can skip tax season. Proceed with extreme caution.

While a single freelancer might get away with silence, a multi-member LLC or S-Corp that fails to file a return—even a “zero return”—can face penalties amounting to thousands of dollars per month. The IRS views these entities as separate legal structures with distinct reporting obligations, regardless of their bank account balance.

This guide covers the specific filing requirements for the 2025 tax season (filing for the 2024 tax year) and planning for the 2025 tax year (filing in 2026), ensuring you avoid the “dormant” partnership traps.

Key Takeaways

• S-Corps Must Always File: An S-Corp must file Form 1120-S every year, even with $0 income and $0 expenses. No exceptions.
• Partnerships Have a Loophole (But It’s Narrow): Domestic partnerships with no income and no expenses generally don’t need to file Form 1065, but filing is often safer to start the statute of limitations.
• The “Per Partner” Penalty is Steep: For returns due in 2025, the late filing penalty is $245 per partner, per month.
• State Taxes Don’t Care About Profit: States like California require an annual franchise tax (e.g., $800) even if the business is inactive.
• Relief is Available: Small partnerships (10 or fewer partners) may qualify for penalty relief under Rev. Proc. 84-35.

Detailed Guide: Filing Requirements by Entity Type

Your filing obligation depends entirely on how your LLC is classified for tax purposes. Do not assume your lack of activity exempts you until you verify your status below.

Entity Classification	Form Required	Filing Requirement with $0 Income	Penalty Risk (2025)
Single-Member LLC (Disregarded Entity)	Form 1040 (Schedule C)	Generally No. If you have no income and no expenses, you typically do not file Schedule C.	Low. (Personal failure-to-file penalties are usually based on tax owed).
Multi-Member LLC (Partnership)	Form 1065	Conditional. Not required if no income AND no expenses. However, filing is recommended.	High. $245/partner/month if the IRS believes you should have filed.
S-Corporation (LLC electing S-Corp)	Form 1120-S	YES. ALWAYS. You must file regardless of activity.	High. $245/shareholder/month.
C-Corporation (LLC electing C-Corp)	Form 1120	YES. ALWAYS. You must file regardless of activity.	High. Penalties apply for failure to file.

Scenario 1: The “Ghost” LLC (Single-Member)

Situation: You formed a Single-Member LLC in late 2024 to do freelance design. You opened a bank account but didn’t deposit money or spend anything.

Verdict: No Federal Filing Required. Because you are a “disregarded entity,” your business activity is reported on your personal return. With zero activity, there is nothing to report on Schedule C. However, check your state requirements—you may still owe an annual report fee or franchise tax.

Scenario 2: The “Silent” Partnership (Multi-Member)

Situation: You and a friend formed an LLC in 2024 to buy real estate. The deal fell through. The LLC has $0 income, but you paid $50 in bank fees.

Verdict: MUST FILE Form 1065. The “no filing” exception for partnerships (Reg. § 1.6031(a)-1) only applies if there is neither income nor expenses/deductions. Because you had $50 in expenses (a deduction), you must file Form 1065. If you had truly $0 income and $0 expenses, you technically don’t have to file, but many professionals advise filing a “zero return” anyway to prevent the IRS from sending a “Where is your return?” notice later.

Scenario 3: The “Empty” S-Corp

Situation: You formed an LLC and elected S-Corp status (Form 2553) thinking you’d make big money. You made $0.

Verdict: MUST FILE Form 1120-S. S-Corps do not have a “dormant” exception. You must file a return stating $0 income. Failing to do so triggers the monthly penalty per shareholder.

The Cost of Silence: 2025 Penalty Breakdown

The IRS increases penalties periodically for inflation. For tax returns due in 2025 (covering the 2024 tax year), the costs for non-compliance are severe.

Partnership & S-Corp Late Filing Penalties

Under IRC Section 6698 (Partnerships) and Section 6699 (S-Corps), penalties are assessed per partner/shareholder for every month the return is late, up to 12 months.

• Returns Due in 2025 (Tax Year 2024): $245 per partner, per month.
• Returns Due in 2026 (Tax Year 2025): Projected to rise to $255 per partner, per month.

Example Calculation (Tax Year 2024):

Imagine a 4-person LLC taxed as a partnership. They forget to file their 2024 return (due March 17, 2025) because they had no income. They finally file in November 2025 (8 months late).

The Math: $245 (penalty) × 4 (partners) × 8 (months) = $7,840 Penalty.

Note: This penalty applies even if the partnership owes $0 in taxes.

Rescue Strategy: Revenue Procedure 84-35

If you receive a penalty notice for a dormant partnership, do not panic. You may qualify for abatement (penalty removal) under Revenue Procedure 84-35.

To qualify for this “Small Partnership Exception,” you generally must meet these criteria:

1. Size: The partnership has 10 or fewer partners.
2. Type: All partners are natural persons (individuals) or estates. (No trusts or corporate partners).
3. Equality: Each partner’s share of items (profit, loss, credits) is the same.
4. Compliance: All partners have timely filed their personal tax returns and reported their share of the partnership activity (even if it was zero).

Action Step: If you receive a penalty notice (CP162), respond immediately with a letter citing Rev. Proc. 84-35, confirming you meet all the requirements.

Common Pitfalls & Mistakes

1. Ignoring State Franchise Taxes

Federal rules are different from state rules. California, for example, requires LLCs to pay an $800 Annual Franchise Tax regardless of income. This payment is typically due by the 15th day of the 4th month of your tax year. Failing to pay this can lead to your business being suspended and accruing interest/penalties.

2. Forgetting Startup Costs

Even if you have no income, you likely have expenses (formation fees, legal advice, domain hosting). If you don’t file a return, you aren’t formally electing to amortize these startup costs. While you can often claim them in the first year you have active business, filing a return helps establish the “start date” of your business intent.

3. The “Final Return” Trap

If you abandoned the LLC, you must formally dissolve it with your state AND file a “Final” tax return with the IRS (checking the “Final Return” box). If you just stop filing, the IRS assumes you are still open and will keep assessing penalties every year.

FAQ: 2025 Filing Season

Can I file a “Zero Return” for my LLC?

Yes, and for Partnerships and S-Corps, it is often the smartest move. A zero return (Form 1065 or 1120-S with all zeros) formally tells the IRS, “We exist, but we did nothing this year.” This satisfies the statute of limitations and prevents automated failure-to-file notices.

What if I haven’t started business operations yet?

If you have simply registered the LLC but haven’t “opened the doors” or incurred expenses, you are in the pre-opening phase. For a partnership with absolutely $0 income and $0 expenses, federal filing is technically not required (Reg. § 1.6031(a)-1). However, S-Corps must file regardless of operational status.

What is the deadline for 2024 returns filed in 2025?

For Partnerships and S-Corps, the deadline is March 17, 2025 (since March 15 is a Saturday). You can file Form 7004 to get an automatic 6-month extension to September 15, 2025.

Conclusion

When it comes to the IRS, silence is rarely golden. While Single-Member LLCs have some breathing room, multi-member partnerships and S-Corps face significant financial risks for failing to file, even with zero income. The penalty of $245 per partner per month is simply too high to gamble with.

The Golden Rule for 2025: If you have an EIN and a multi-member or corporate structure, file a zero return. It takes minimal time and serves as cheap insurance against aggressive IRS penalty algorithms.
