Running a small business comes with many responsibilities, including filing taxes. The IRS sets specific income thresholds that determine when a company must file a return. While some businesses must file regardless of their earnings, others only need to file if their net income exceeds a certain amount. Understanding the IRS’s income thresholds and tax requirements is crucial for small business owners. It not only helps them avoid penalties but also ensures compliance.
1. Minimum Income Requirements for Filing Taxes
The IRS sets tax filing requirements based on the business structure. Sole proprietors, LLCs, partnerships, and corporations each have their own distinct rules and thresholds.
According to the IRS, sole proprietors and self-employed individuals must file a return if they earn $400 or more in net income. LLCs and partnerships have separate rules, and corporations must file regardless of income.
2. Sole Proprietors and Self-Employed Individuals
Sole proprietors and independent contractors, who operate without a separate legal business entity, report their income on Schedule C of their personal tax return.
When Must a Sole Proprietor File Taxes?
- If a sole proprietor earns $400 or more in net income, they must file a tax return.
- Even if no federal income tax is due, self-employment tax still applies.
Self-Employment Tax
The self-employment tax rate is 15.3%, covering Social Security (12.4%) and Medicare (2.9%). These taxes apply to net earnings above $400.
Since employers usually cover half of these taxes for W-2 employees, self-employed individuals must pay the full amount themselves.
3. LLCs and Partnerships: What to Know
Limited Liability Companies (LLCs) and partnerships have different tax filing rules depending on ownership structure.
Single-Member LLCs
- Treated as a disregarded entity by the IRS, meaning income is reported on Schedule C, just like a sole proprietorship.
- Must file a return if net earnings exceed $400.
Multi-Member LLCs and Partnerships
- Required to file Form 1065 (U.S. Return of Partnership Income) even if the business had no earnings.
- Income, losses, and deductions pass through to the owners, who report them on Schedule K-1.
Partners may owe self-employment tax on their share of earnings.
4. S Corporations and C Corporations
Corporations face stricter filing rules, often requiring tax returns regardless of income.
S Corporations (S Corps)
- Must file Form 1120-S annually.
- Profits pass through to shareholders, who report them on their personal tax returns.
- Shareholders who work in the business must pay themselves a reasonable salary subject to payroll taxes.
C Corporations (C Corps)
- Required to file Form 1120 regardless of income.
- Subject to a 21% corporate tax rate on profits.
- Can retain earnings instead of passing them to owners, unlike S Corps.
Since corporations have more complex tax structures, many business owners seek professional guidance to ensure compliance.
5. Deductions and Taxable Income Adjustments
Deductions can reduce taxable income, impacting whether a business meets the IRS filing threshold.
Common Small Business Deductions
- Home Office Deduction – If a portion of your home is used exclusively for business.
- Business Mileage – Deduct 67 cents per mile for business travel in 2024.
- Equipment and Supplies – Office furniture, software, and business tools.
- Marketing and Advertising – Costs for websites, ads, and promotional materials.
- Health Insurance Premiums – Self-employed individuals can deduct their health insurance costs.
A business making $10,000 in revenue with $7,000 in deductible expenses has a net income of $3,000—meaning they must file a return.
6. Consequences of Not Filing When Required
Failing to file taxes when required can lead to penalties, interest, and potential legal issues.
IRS Penalties for Not Filing
- Failure-to-File Penalty – 5% of unpaid taxes per month, up to 25%.
- Failure-to-Pay Penalty – 0.5% per month on unpaid taxes.
- Interest on Late Payments – Accrues daily until the balance is paid.
Legal Risks
- The IRS can audit businesses that fail to report earnings.
- Tax liens may be issued if taxes remain unpaid for an extended period.
- In extreme cases, failure to file can lead to criminal charges for tax evasion.
7. Filing Deadlines and Tax Payment Obligations
Small businesses must meet specific tax deadlines to avoid penalties.
Key Tax Deadlines
- Sole Proprietors & Single-Member LLCs – April 15 (Form 1040 with Schedule C).
- Partnerships & Multi-Member LLCs – March 15 (Form 1065).
- S Corporations – March 15 (Form 1120-S).
- C Corporations – April 15 (Form 1120).
Estimated Tax Payments
Businesses expecting to owe $1,000 or more in taxes must make quarterly estimated tax payments:
- April 15
- June 15
- September 15
- January 15 (of the following year)
Missing estimated tax payments can result in additional penalties.
8. How to Stay Compliant with Tax Laws
Keeping up with tax rules can be overwhelming, but business owners can take steps to stay compliant:
- Track all income and expenses – Use accounting software or a professional bookkeeper.
- Understanding and maximizing deductions – By claiming eligible business expenses, you can significantly reduce your tax burden and keep more of your hard-earned money.
- Meet filing deadlines – Set reminders to avoid penalties.
- Pay estimated taxes – If required, make quarterly payments to the IRS.
- Consult a tax professional – If unsure, work with a CPA to ensure proper tax filings.
Conclusion
Small businesses must file taxes when earnings exceed IRS thresholds. Sole proprietors and self-employed individuals must file if net income exceeds $400, while partnerships and corporations need to file regardless of income.
Understanding tax obligations helps small business owners avoid costly penalties and stay in compliance. By tracking expenses, knowing deductions, and filing on time, businesses can reduce their tax burden and focus on growth.
