Being self-employed in Kansas comes with freedom to set your own schedule and earn on your terms but it also means you’re fully responsible for your taxes. Unlike a regular W-2 employee, no one is withholding taxes for you. You need to calculate, report, and pay taxes yourself at both the federal and state level. Missing deadlines or underestimating your tax obligations can result in penalties, interest, or unnecessary stress.
This guide breaks down Kansas self-employed taxes for 2025–2026 in simple terms. You’ll learn how your income is taxed, what forms to file, how estimated taxes work, key deductions and credits, and practical steps to stay compliant. It’s written for anyone in Kansas working independently, from freelancers and consultants to small business owners and gig economy workers.
Who Counts as Self-Employed in Kansas?
In Kansas, you’re considered self-employed if you earn money outside a traditional employer–employee relationship. This includes:
- Freelancers and consultants
- Independent contractors receiving 1099-NEC forms
- Sole proprietors
- Single-member LLC owners
- Gig workers and delivery drivers
- Independent service providers
If your net earnings from self-employment are $400 or more, you must file a federal tax return and pay self-employment tax.
Federal Taxes You Need to Know
Even before considering Kansas state taxes, self-employed individuals have federal obligations.
1. Self-Employment Tax
Self-employment tax covers Social Security and Medicare contributions. As a self-employed worker, you pay both the employee and employer portions.
For 2025–2026, rates are:
- 12.4% for Social Security (up to the annual cap)
- 2.9% for Medicare (no cap)
- An extra 0.9% Medicare tax if your income is above certain thresholds
You calculate this using Schedule SE based on your net business income from Schedule C.
2. Federal Income Tax
In addition to self-employment tax, you also pay federal income tax on your taxable income after deductions. Federal income tax rates are progressive, meaning higher earnings are taxed at higher rates.
Kansas State Taxes for Self-Employed Workers
Kansas taxes self-employed individuals similarly to other residents, but without withholding. That means you’re responsible for making sure your state income tax is calculated and paid on time.
How Kansas Taxes Self-Employment Income
Kansas taxes net taxable income, which includes your self-employment earnings after allowable business expenses. Income tax is progressive, meaning as your income grows, your tax rate increases.
Kansas generally starts with your federal adjusted gross income (AGI) and applies state-specific adjustments to calculate state taxable income.
Kansas Income Tax Rates for 2025–2026
Kansas uses a simple progressive structure:
- Lower rate for lower-income taxpayers
- Higher rates as income increases
Your exact tax bill depends on:
- Filing status (single, married filing jointly, etc.)
- Taxable income after deductions
- Eligible tax credits
It’s important to calculate carefully to avoid surprises.
How to Calculate Kansas Self-Employed Taxable Income
Step 1: Determine Net Business Income
Start with your total business income and subtract ordinary business expenses. Use Schedule C to calculate this.
Common deductible expenses include:
- Advertising and marketing
- Office supplies
- Software subscriptions and online tools
- Phone and internet bills
- Business insurance
- Professional services
- Vehicle and travel expenses
Step 2: Apply Kansas Adjustments
Kansas generally starts with your federal AGI, but some deductions may be treated differently. Adjustments may include:
- Additions for certain tax-exempt income
- Subtractions for specific deductions allowed by Kansas
Step 3: Apply Kansas Tax Rates
Once taxable income is determined, apply the Kansas income tax brackets to calculate your state tax owed.
Perfect! Let’s break it down step by step with a clear, realistic example showing how a Kansas self-employed worker would calculate both federal and state taxes, including deductions and estimated payments.
Example: Calculating Taxes for a Kansas Self-Employed Worker
Scenario:
- Name: Sarah
- Business: Freelance graphic design
- Total income for 2025: $80,000
- Business expenses: $15,000
- Filing status: Single
- No children or dependents
- Health insurance premiums: $4,500/year
- Retirement contributions: $6,000 to a SEP IRA
We’ll calculate her federal self-employment tax, federal income tax, Kansas state income tax, and estimated quarterly payments.
Step 1: Calculate Net Business Income
Sarah’s total income: $80,000
Business expenses: $15,000
Net business income = 80,000 – 15,000 = 65,000
This is the amount used for federal self-employment tax and federal income tax calculations.
Step 2: Calculate Federal Self-Employment Tax
Self-employment tax rate: 15.3% (12.4% Social Security + 2.9% Medicare)
Self-employment tax = 65,000 × 15.3% = $9,945
Note: Only 92.35% of net income is subject to self-employment tax, so calculation is:
- Adjusted for SE tax: 65,000 × 0.9235 = 60,028
- SE tax = 60,028 × 15.3% ≈ $9,184
Half of this ($9,184 ÷ 2 ≈ $4,592) is deductible on her federal income tax return.
Step 3: Calculate Federal Taxable Income
- Net business income: $65,000
- Less half SE tax: $4,592
- Less retirement contribution: $6,000
- Less health insurance premiums: $4,500
Federal taxable income = 65,000 – 4,592 – 6,000 – 4,500 ≈ $49,908
Using 2025 federal tax brackets for a single filer (approximate):
- 10% on first $11,000 → $1,100
- 12% on next $33,725 → $4,047
- 22% on remaining $5,183 → $1,140
Total federal income tax ≈ $6,287
Step 4: Calculate Kansas State Tax
Kansas starts with federal taxable income and applies state-specific adjustments. Let’s assume Sarah has no special additions or subtractions.
Kansas income tax rates for 2025 (approximate for single filer):
- 3.1% on first $15,000
- 5.25% on next $25,000
- 5.7% on income above $40,000
Taxable income for Kansas: $49,908
- First $15,000 × 3.1% = $465
- Next $25,000 × 5.25% = $1,312.50
- Remaining $9,908 × 5.7% ≈ $564
Total Kansas state tax ≈ $2,341
Step 5: Total Tax Liability
- Federal self-employment tax: $9,184
- Federal income tax: $6,287
- Kansas state income tax: $2,341
Total taxes for 2025 ≈ $17,812
Step 6: Calculate Estimated Quarterly Payments
Estimated taxes are paid quarterly (April, June, September, January).
Total taxes ÷ 4 ≈ 17,812 ÷ 4 ≈ $4,453 per quarter
Sarah should set aside this amount every quarter to avoid penalties for underpayment.
Step 7: Tips to Reduce Taxes
- Maximize deductions: Keep all business receipts, mileage logs, and home office expenses.
- Contribute to retirement accounts: Higher contributions reduce taxable income.
- Deduct health insurance premiums: Reduces both federal and state taxable income.
- Separate business and personal accounts: Makes recordkeeping and audits easier.
- Adjust quarterly payments if income changes: Prevent overpaying or underpaying.

The space must be your primary place of business or used for regular client work.

Choosing a Business Structure and Its Tax Impact
Your business structure affects how income is reported and taxed.

Good recordkeeping makes taxes simpler and protects you in case of an audit.
What to Keep

- Business expense receipts
- Mileage logs
- Bank and credit card statements

How Long to Keep Records
Keep tax records for at least three to five years. Accounting software can make tracking income and expenses easier.
Common Mistakes to Avoid

Even small mistakes can lead to penalties or lost savings.
When to Consider a Tax Professional
Consider professional help if:
- Your income is irregular or comes from multiple sources

- You want guidance on deductions or retirement contributions
- You’re thinking of electing S corporation status
A tax professional can save you money and stress.
Planning Ahead for 2026
