Being self-employed in Mississippi offers flexibility, independence, and control over how you earn money. Whether you are freelancing, running a small business, driving for a gig platform, or earning income through side work, self-employment also means you are fully responsible for your taxes.
Unlike traditional employees, self-employed individuals do not have taxes withheld automatically from their pay. That responsibility falls entirely on you. If you are not prepared, tax season can bring unexpected bills, penalties, and cash flow stress.
This guide to Mississippi self-employed taxes for 2025 – 2026 explains everything you need to know in clear, easy-to-read language. You will learn who is considered self-employed, which taxes apply, how estimated payments work, what deductions you can claim, and how to plan ahead so tax season does not catch you off guard.
Self-Employment Tax Explained
Self-employment tax covers Social Security and Medicare contributions. When you are employed, your employer pays half of these taxes. When you are self-employed, you pay both portions yourself.
Self-employment tax includes:
- Social Security tax on eligible earnings
- Medicare tax on all net earnings
This tax is calculated using Schedule SE and is separate from federal and state income taxes. Even if your business does not make a large profit, you may still owe self-employment tax if your net earnings exceed the minimum threshold.
Who Is Considered Self-Employed in Mississippi
In Mississippi, you are considered self-employed if you earn income without taxes being withheld by an employer. Instead of receiving a paycheck with automatic deductions, you are responsible for tracking income, reporting earnings, and paying your own taxes.
Self-employment includes more than just business owners. You may be considered self-employed if you earn income in any of the following ways:
- Freelancers or consultants providing services independently
- Independent contractors who receive 1099 forms
- Gig workers such as rideshare drivers, delivery drivers, and online sellers
- Sole proprietors running a business under their own name or a registered name
- Single-member LLC owners whose income passes through to their personal tax return
- Partners in a partnership earning a share of business profits
If you receive income directly from clients, platforms, or customers and no taxes are withheld, Mississippi and the IRS treat you as self-employed.
Why Self-Employed Taxes Work Differently
When you work for an employer, taxes are automatically taken out of each paycheck. This includes federal income tax, Social Security, and Medicare. As a self-employed individual, that system does not exist.
This means you must take responsibility for several things on your own:
- Estimating how much tax you owe
- Setting money aside throughout the year
- Making tax payments on your own schedule
- Filing additional tax forms
Without proper planning, many self-employed individuals are surprised by how much they owe at tax time. Understanding how self-employed taxes work ahead of time helps you stay in control and avoid penalties.
Federal Self-Employment Tax Explained
One of the biggest tax responsibilities for self-employed individuals is self-employment tax. This tax covers Social Security and Medicare.
Employees split these taxes with their employer. Self-employed individuals pay both portions themselves.
Self-employment tax generally includes:
- 12.4 percent for Social Security, up to an annual income limit
- 2.9 percent for Medicare, with no income cap
Together, this usually equals 15.3 percent of your net business income.
Social Security tax only applies up to a certain income threshold that adjusts each year. Medicare tax applies to all net income, and higher earners may owe an additional Medicare tax.
This tax is calculated using Schedule SE and paid with your federal tax return.
Federal Income Tax for Self-Employed Individuals
In addition to self-employment tax, you must also pay federal income tax on your profits.
Federal income tax follows a progressive system, which means different portions of your income are taxed at different rates. Your final tax bill depends on several factors, including:
- Your total taxable income after expenses
- Your filing status
- Your deductions and credits
Because no taxes are withheld automatically, self-employed individuals must plan for federal income tax throughout the year.
Mississippi State Income Tax for the Self-Employed
Mississippi imposes state income tax on self-employed individuals. Your business income flows through to your personal Mississippi tax return, just like it does for federal taxes.
Mississippi uses a graduated income tax system. Lower income is taxed at lower rates, while higher income is taxed at higher rates.
You owe Mississippi state income tax on your net business income after deducting allowable expenses. Rates and income thresholds may change, so it is important to review Mississippi’s current tax guidelines before filing.
Estimated Quarterly Taxes in Mississippi
Most self-employed individuals in Mississippi are required to make estimated tax payments throughout the year. These payments help prevent a large tax bill at filing time.
Estimated payments usually cover:
- Federal income tax
- Self-employment tax
- Mississippi state income tax
Payments are typically due four times per year and are spaced across the calendar year. Missing a payment or underpaying can result in penalties and interest, even if you pay the full balance later.
How to Estimate Your Tax Payments
Estimating your tax payments becomes easier when you break the process into simple steps.
A practical approach includes:
- Estimating your total annual income
- Subtracting expected business expenses
- Calculating self-employment tax
- Estimating federal income tax
- Estimating Mississippi state income tax
- Dividing the total tax amount by four
Many self-employed individuals set aside between 25 and 35 percent of their income for taxes. The right percentage depends on income level, deductions, and filing status.
Mississippi Sales Tax Responsibilities
If your business sells taxable products or services in Mississippi, you may need to collect and remit sales tax.
This commonly applies to:

Business Registration and Tax IDs in Mississippi
Depending on your business structure, you may need to register your business with the state and obtain specific tax identification numbers.
This may include:
- A Mississippi Tax ID
- A federal Employer Identification Number

Accurate mileage logs and receipts are essential for claiming this deduction properly.

FAQs: Mississippi Self-Employed Taxes
What taxes do self-employed individuals in Mississippi have to pay?
Self-employed individuals in Mississippi are responsible for federal self-employment tax, which covers Social Security and Medicare at 15.3% on net earnings, as well as federal income tax based on taxable income. Additionally, Mississippi imposes state income tax on net earnings using a progressive rate structure. Depending on your location, you may also owe local business or licensing taxes.
Do self-employed workers in Mississippi pay quarterly taxes?
Yes. If you expect to owe $1,000 or more in federal taxes after withholding and credits, you are generally required to make estimated quarterly tax payments to the IRS. Mississippi may also require state estimated payments if your withholding does not cover your anticipated state tax liability.
When are estimated tax payments due for self-employed earners?
For 2025–2026, estimated tax payments are typically due on April 15, June 15, and September 15 of the tax year, with the fourth payment due on January 15 of the following year. If a due date falls on a weekend or holiday, it shifts to the next business day. These payments help avoid penalties and interest for underpayment.
How do I calculate Mississippi state income tax as a self-employed person?
To calculate Mississippi state income tax, start with your federal adjusted gross income and make any Mississippi-specific additions or subtractions. Mississippi uses a progressive tax rate, so your tax depends on your income level. Self-employed individuals report their business income on federal Schedule C and include it on their Mississippi Form 80-105 to determine state taxable income.
Can I deduct business expenses on my self-employment taxes?
Yes. Deductible business expenses reduce your taxable income for both federal and state purposes. Common deductions include office supplies and equipment, home office expenses if you qualify, marketing and advertising costs, professional services like accounting or legal fees, business travel and meals, and health insurance premiums for self-employed individuals. Properly tracking expenses can significantly reduce your tax liability.
What is the self-employment tax rate?
The federal self-employment tax rate is 15.3%, which covers Social Security and Medicare contributions. Half of this tax can be deducted as a business expense on your federal return, reducing your taxable income.
Do I need a separate Mississippi tax ID or registration?
If you operate as a sole proprietor under your own name, you typically use your Social Security Number for tax purposes. However, if you operate under a business name (DBA) or form an LLC or partnership, you may need to register with the Mississippi Secretary of State and obtain an Employer Identification Number (EIN).
How does the Mississippi Department of Revenue handle self-employed returns?
Self-employed individuals file an individual state income tax return using Form 80-105. Business income reported on federal Schedule C should be included to calculate Mississippi taxable income. Any relevant schedules for deductions or credits should be attached to ensure proper computation of your tax liability.
Are self-employed people in Mississippi eligible for tax credits?
Yes. Depending on your situation, you may qualify for the Mississippi Child Tax Credit or the Earned Income Tax Credit if eligible at the federal level. It is important to review current 2025–2026 rules, as eligibility and amounts may change from year to year.
What happens if I miss a payment or file late?
Missing estimated payments can lead to penalties for underpayment at both the federal and state levels. Filing your return late may trigger additional late-filing penalties and interest. While filing an extension can help avoid late-filing penalties, it does not extend the time to pay taxes owed.
Should I hire a tax professional?
Hiring a certified tax professional can be beneficial if your income is complex, you operate multiple businesses, or you are unsure about deductions and estimated payments. A professional can help ensure compliance, reduce errors, and potentially save money by identifying applicable deductions and credits.
Where can I find Mississippi tax forms and instructions?
Federal forms are available on the IRS website, while Mississippi forms and instructions can be downloaded from the Mississippi Department of Revenue website. Both sources provide worksheets, filing instructions, and online payment options.
