If your business made no money this year, you almost certainly still have to file a return, but in most cases you won’t owe federal income tax on the business itself. The trap is treating “no profit” as “no paperwork.” Skipping the return can cost you $255 per owner per month for partnerships and S Corporations, wipe out a loss you could have used against future profits, and leave the IRS’s audit clock stopped indefinitely on your open year. Whether you also owe self-employment tax, payroll tax, sales tax, or state franchise fees depends on facts that have nothing to do with your bottom line.
Filing Is Not the Same as Paying
Federal income tax is calculated on net income: what’s left after legitimate expenses. If a business took in $200,000 and spent $200,000 on qualifying costs, it owes no federal income tax on that activity. The return is still what documents those expenses, proves the loss, and preserves your right to use that loss in later years. Without the filed return, none of it exists in the IRS’s records.
Filing thresholds, on the other hand, are often tied to gross income or to the entity type itself. That’s why the answer to “do I have to file” almost always ends up being yes, even when the answer to “do I owe” is no.
What Each Business Type Owes When There’s No Profit
Sole Proprietorships and Single-Member LLCs
Sole proprietors and single-member LLCs taxed as disregarded entities report business activity on Schedule C, attached to Form 1040. Schedule C is required if net self-employment earnings hit $400 or more, which is also the point at which self-employment tax kicks in. Even below that number, you need to file if your gross self-employment income reaches $5,000 or more.1Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
Your personal filing threshold matters too. For 2026, single filers generally must file if total gross income exceeds $16,100, and joint filers face $32,200.2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Self-employment earnings of $400 or more trigger a return regardless of whether your overall income clears those numbers.
Even when nothing in that list forces you to file, filing Schedule C in a loss year is the only way to document the loss for later use.
Partnerships and Multi-Member LLCs
Partnerships and multi-member LLCs taxed as partnerships must file Form 1065 every year. The single narrow exception is a partnership that neither receives income nor incurs any expenses treated as deductions or credits.3Internal Revenue Service. 2025 Instructions for Form 1065 If the business spent a single deductible dollar, the return is required.
The partnership itself pays no income tax. Form 1065 is informational, and income or losses pass through to partners on Schedule K-1.4Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income But the penalty for filing late or incomplete is $255 per partner for each month or partial month, up to 12 months.5Internal Revenue Service. Failure to File Penalty A four-partner LLC that files six months late owes $6,120 in penalties on a business that earned nothing.
S Corporations
S Corporations must file Form 1120-S every year without exception. Income and losses pass through to shareholders on Schedule K-1. The penalty for a late or incomplete Form 1120-S when no tax is due is $255 per shareholder per month, up to 12 months.6Internal Revenue Service. Instructions for Form 1120-S (2025)
C Corporations
C Corporations must file Form 1120 every year until they formally dissolve. There is no income threshold and no exception for inactivity.7Internal Revenue Service. Instructions for Form 1120 (2025) A C Corp that’s been dormant for three years owes a return for each of those years. If it had expenses and no revenue, filing is what captures the resulting loss for future use.
Self-Employment Tax With No Profit
Self-employment tax covers Social Security and Medicare for people working for themselves, at a combined 15.3% (12.4% Social Security, 2.9% Medicare).1Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) It applies only to net earnings from self-employment, not gross revenue.
If your Schedule C shows zero or negative net income, your self-employment tax is zero. It only kicks in once net earnings reach $400. You still file Schedule C to show the IRS how you arrived at that number.
Why Filing a Loss Year Actually Pays Off
When expenses exceed income, the result is a net operating loss. An NOL is a tax asset you can carry forward to offset income in future profitable years. You can only claim it if you file a return documenting the loss in the year it occurs.
Under current law, NOLs arising after 2017 carry forward indefinitely, but the deduction in any given year is capped at 80% of taxable income.8Office of the Law Revision Counsel. 26 U.S. Code 172 – Net Operating Loss Deduction You can’t wipe out an entire future year’s tax bill with one carryforward, but the unused portion rolls forward again.
Carrybacks are generally gone for losses arising after 2020, with limited exceptions for farming and certain insurance companies.8Office of the Law Revision Counsel. 26 U.S. Code 172 – Net Operating Loss Deduction So the loss only helps forward, and only if you file to establish it.
When No Profit Still Means You Owe Tax: The Hobby Rule
Reporting losses year after year invites the IRS to reclassify your activity as a hobby, which changes the math against you. Under Section 183, if the IRS decides you’re not operating with a genuine profit motive, your ability to deduct expenses against the activity’s income becomes severely restricted.9Office of the Law Revision Counsel. 26 U.S. Code 183 – Activities Not Engaged in for Profit
The presumption: an activity that shows a profit in at least three of five consecutive years is treated as a for-profit business. Fail that test and you carry the burden of proving profit motive, with the IRS weighing whether you keep proper books, have changed methods to improve profitability, and depend on the activity for your livelihood.9Office of the Law Revision Counsel. 26 U.S. Code 183 – Activities Not Engaged in for Profit
Get reclassified and you must still report all gross income from the activity, but you can only deduct expenses up to that income. Excess expenses are disallowed, and you cannot use hobby losses to offset wages or other income. This is the scenario where the answer flips: you may owe tax on the money that came in even though you spent more than you earned.
Obligations That Ignore Your Bottom Line
Several filing duties run on their own tracks and don’t care whether your business turned a profit.
Payroll Tax Returns
Once you file your first Form 941, you must keep filing quarterly even in quarters with no wages paid. The only way out is to file a final return by checking the appropriate box and noting the last date wages were paid, or to qualify as a seasonal employer.10Internal Revenue Service. Instructions for Form 941 (Rev. March 2026) Slowing down or pausing isn’t enough. The IRS expects a return every quarter until you formally end the obligation.
Sales Tax
If you’re registered to collect sales tax, most states require you to file on your assigned schedule even in periods with zero sales. These “zero returns” confirm no taxable activity occurred. The filing duty typically continues until you formally close your sales tax account with the state.
1099s to Contractors
Even a business that lost money may have paid contractors, freelancers, or service providers. If you paid a non-employee $2,000 or more during 2026, you’re required to file Form 1099-NEC reporting that payment.11Internal Revenue Service. Publication 1099 General Instructions for Certain Information Returns The threshold rose from $600 for tax years beginning after 2025. The obligation is independent of your profit or loss, and missed information returns carry their own penalties.
State Franchise Taxes and Annual Reports
States don’t care whether your federal return shows a profit. Many charge a minimum franchise tax or privilege tax on LLCs and corporations regardless of income, essentially a fee for the legal right to exist as an entity there. Annual report fees to keep your entity in good standing with the Secretary of State are also fixed costs unrelated to revenue.
Ignoring these is often worse than the fees themselves. States can administratively dissolve or revoke the charter of a business that doesn’t file annual reports or pay franchise taxes, and reinstating a revoked entity usually costs significantly more than the original fees plus back-payment of every missed year with penalties and interest.
What Happens If You Just Don’t File
Doing nothing in a no-profit year is the most expensive response.
For individual and corporate returns filed more than 60 days late, the minimum penalty is $525 or 100% of the unpaid tax, whichever is smaller.5Internal Revenue Service. Failure to File Penalty When tax is owed, the standard failure-to-file penalty runs at 5% of the unpaid balance per month, capped at 25%. For partnerships and S Corps, the per-owner-per-month penalty applies whether or not any tax was due.
The statute of limitations problem is worse than the money. Normally the IRS has three years from the filing date to audit and assess additional tax. If you never file, that clock never starts, and the IRS can come after you for an unfiled year with no expiration.12Internal Revenue Service. Help Yourself by Filing Past-Due Tax Returns Filing a return that shows zero at least starts the clock in your favor.
An unfiled return also erases any NOL you could have claimed from that year. A loss that might have cut your tax bill in a future profitable year simply vanishes if you never document it.
How to Actually End the Filing Obligation
If you’re done with the business, the returns don’t stop until you formally close it. Skipping next year’s return doesn’t close anything; it triggers penalties.
Partnerships and S Corps file a final Form 1065 or 1120-S for the last year of operations and check the “final return” box near the top, marking each K-1 as final as well.13Internal Revenue Service. Closing a Business C Corps do the same with Form 1120. Sole proprietors file a final Schedule C with their personal return for the closing year.
If you’ve been filing Form 941, submit a final quarterly return and check the box indicating it’s your last.10Internal Revenue Service. Instructions for Form 941 (Rev. March 2026) To deactivate your EIN, send the IRS a letter with the entity’s name, EIN, and the reason for closing.14Internal Revenue Service. If You No Longer Need Your EIN All outstanding returns must be filed and any taxes owed must be paid before the IRS will process the deactivation.
On the state side, file articles of dissolution with your Secretary of State and close out any sales tax or employer withholding accounts. Until both the federal and state closure steps are complete, the government considers the business alive and expects its returns.
