Kansas Self-Employed Tax Calculator: What the Sunflower State Takes From Freelance Profit
The LLC pass-through exemption is long gone, the brackets were rebuilt in 2024, and the federal SE tax never went anywhere. On $78,000 of Kansas freelance profit the combined bill is about $21,500 — here is every line of it.

The formula: total tax = SE tax (15.3% × 92.35% of profit) + federal income tax + Kansas income tax (effective ≈5% on mid-five-figure profits).
The Kansas myth that still costs freelancers money
Search for Kansas freelance tax advice and you will still find articles celebrating the state's famous pass-through exemption — the 2013 law that zeroed out state income tax on LLC and self-employment income. That law was repealed in 2017 after blowing a hole in the state budget. Today, Kansas taxes your freelance profit like any other income, under a two-bracket system topped by a 5.58% rate.
The bigger number is the one Kansas shares with every other state: the federal self-employment tax. On $78,000 of profit it is roughly $11,000 before income tax begins, because there is no employer quietly paying half. Add about $7,600 of federal income tax and $2,900 to Kansas, and the freelancer who reserved a casual 20% is $6,000 short in April.
This guide walks a complete Kansas example line by line, shows the combined bill at five profit levels, and closes the loop on the border question Kansas City freelancers ask constantly: which side of the Missouri line you live on changes the paperwork more than the total. The numbers are 2026 estimates — Kansas has adjusted its brackets repeatedly this decade, so confirm the current schedule each January.
How to calculate your Kansas self-employed taxes in five steps
- 01
Find your net profit first
Kansas freelance tax starts where every state calculation starts: revenue minus deductible expenses. A consultant billing $92,000 with $14,000 of software, equipment, insurance and home-office costs works from $78,000. Kansas taxes that profit fully — the famous pass-through exemption that once zeroed out state tax on LLC income was repealed years ago, and advice articles from that era still circulate.
- 02
Apply the 15.3% federal self-employment tax
The SE tax — 12.4% Social Security plus 2.9% Medicare — hits 92.35% of net profit up to the Social Security wage cap. On $78,000 that is roughly $11,000, with half deductible against income tax. No employer splits this with you anymore; the full 15.3% is why freelance tax bills shock people in their first year.
- 03
Add federal income tax
After the standard deduction and the half-SE-tax adjustment, a single filer with $78,000 of Kansas freelance profit owes roughly $7,600 of federal income tax — mostly at 12%, with the top slice at 22%. This is the layer quarterly estimated payments exist for, and the IRS charges interest when it arrives late.
- 04
Apply Kansas's graduated income tax
Kansas restructured its brackets in 2024: two rates, topping out at 5.58% on higher incomes, with sub-S Social Security and retirement income exempted and the standard deduction raised. On $78,000 of freelance profit, the effective state rate works out to roughly 5%, or about $2,900. Confirm the current brackets each year — Kansas has adjusted them repeatedly this decade.
- 05
Set the reserve and pay quarterly
Add the three layers and a Kansas freelancer at $78,000 of profit owes roughly $21,500 — about 28%. Move that percentage into a separate account as each payment lands, and pay estimates in April, June, September and January. Kansas follows the federal estimated-payment calendar, so one set of dates covers both.
A worked example: $78,000 of profit in Wichita
A single freelance marketing consultant with $92,000 of revenue and $14,000 of expenses. Watch the federal layers dominate the bill — and notice that even after Kansas's 2024 bracket restructuring, the state line is the smallest of the three.

Kansas freelance tax at five profit levels
Combined federal SE tax, federal income tax and Kansas state tax at common profit levels for a single filer, using the post-2024 bracket structure. The effective rate climbs past 30% around six figures of profit.
| Net profit | SE tax | Federal income tax | Kansas tax | Effective rate |
|---|---|---|---|---|
| $35,000 | $4,946 | $950 | $1,050 | ≈20% |
| $55,000 | $7,772 | $3,300 | $1,850 | ≈23% |
| $78,000 | $11,026 | $7,560 | $2,900 | ≈28% |
| $110,000 | $15,543 | $14,300 | $4,600 | ≈31% |
| $150,000 | $19,320 | $23,100 | $7,000 | ≈33% |
Signs your Kansas tax setup needs work
Each of these has an April price tag. The first one — the repealed exemption — still shows up in freelancer forums every single year.
- !You still believe Kansas LLC income is exempt from state tax — it has not been for years
- !Your reserve is sized for the state tax but not the 15.3% SE tax
- !Quarterly payments happen when cash flow allows instead of on the calendar
- !You set your day rate from a salary comparison with no tax loading
- !Your expenses are reconstructed from bank statements every March
- !You do not know Kansas restructured its brackets in 2024
- !Client deposits land in the same account as your rent money
- !You cannot name your combined effective rate within five points
The pass-through exemption: dead, buried, still quoted
From 2013 to 2017, Kansas ran one of the most radical tax experiments in the country: pass-through business income, including most freelance and LLC profit, was exempt from state income tax. Hundreds of thousands of filers restructured to claim it, the state budget cratered, and in 2017 the legislature repealed the exemption over the governor's veto. It has been dead for nearly a decade.
It has not stopped being quoted. Advice articles written during the experiment still rank in search results, and forum answers still repeat it. Freelancers who moved to Kansas partly on that promise, or who structured an LLC around it, occasionally discover the repeal only when a return is prepared. If any source tells you Kansas LLC income is state-tax-free, check its date — it is describing a law from another era.
The current reality is conventional: a two-bracket income tax with a 5.58% top rate, a decent standard deduction, and full taxation of self-employment profit. Unremarkable, moderate, and — unlike the exemption — real.
A quarterly routine that survives a bad quarter
Project in January, pay four times, adjust every quarter. Estimate the year's profit, compute roughly 28% as the combined federal, SE and Kansas bill at common income levels, divide by four, and automate the transfers for April, June, September and January. Both the IRS and Kansas follow the same dates, so one calendar covers everything.
The adjustment step is what makes the system resilient. Freelance income is lumpy: a strong spring means the June payment should rise; a client collapse in August means September's can fall. Underpaying a quarter when income genuinely fell is not a failure — it is what estimated payments are for. What triggers penalties is underpaying while income was strong.
And keep the reserve out of reach: a separate high-yield savings account, funded the day each client payment lands. A tax reserve visible in your checking balance is spending money with extra steps. The freelancers who automate this never meet the April panic; everyone else meets it annually.
Frequently asked questions
How much is self-employment tax in Kansas?
Kansas adds no state-level SE tax. The federal 15.3% applies to 92.35% of net profit, then federal income tax and Kansas's graduated income tax — topping out at 5.58% — stack on top. On $78,000 of profit the combined bill is roughly $21,500, or about 28%: $11,000 SE tax, $7,600 federal income tax and $2,900 to Kansas.
What is Kansas's income tax rate for freelancers?
Kansas taxes freelance profit under its individual income tax, restructured in 2024 into a two-bracket system with a top rate of 5.58%. The effective rate on a typical five-figure freelance profit lands around 5% after the standard deduction. Kansas has adjusted its brackets several times this decade, so verify the current schedule each year rather than reusing an old rate.
Is Kansas LLC or pass-through income still tax-free?
No — and this is the most expensive myth in Kansas freelancing. From 2013 to 2017, Kansas exempted pass-through business income from state income tax. That experiment ended in 2017 and the exemption was fully repealed. Today your freelance or LLC profit is taxed like any other income. Any article or forum post claiming otherwise is citing a law that no longer exists.
Do I need to make quarterly estimated payments in Kansas?
Yes, if you expect to owe $1,000 or more federally — and Kansas expects its own estimates when your state liability crosses its threshold. Both follow the same calendar: April 15, June 15, September 15 and January 15. Paying everything in April instead triggers underpayment penalties at both levels.
What percentage should a Kansas freelancer save for taxes?
At common freelance profit levels of $50,000 to $120,000, hold 26% to 30% of every payment for the combined federal, SE and Kansas bill. Transfer it to a separate account the day money arrives. The freelancers who get hurt are never the ones who estimated slightly wrong — they are the ones who left the reserve in checking and spent it.
I live in Kansas City, Kansas — do I pay the 1% earnings tax?
No. The 1% earnings tax belongs to Kansas City, Missouri, and applies to people who live or work on the Missouri side. Kansas-side residents file Kansas state tax only. If you live in Kansas but perform work in Kansas City, Missouri, the Missouri city may claim an apportioned share — keep a record of where you actually worked.
What expenses can a Kansas freelancer deduct?
The standard federal list, which Kansas follows: software and subscriptions, equipment, professional insurance, marketing, a qualifying home office, business mileage, training, and the business share of phone and internet. A missed $1,000 deduction costs roughly $300 in combined federal, SE and state tax, which is why contemporaneous records beat March reconstruction every time.
Does Kansas tax income from out-of-state clients?
Yes — as a Kansas resident your freelance profit is Kansas income wherever your clients are located. Working for clients in California or New York does not create tax obligations there as long as the work is performed from Kansas. Your home state is the only state return your freelance income normally touches.
Should I form an S-corp in Kansas to save tax?
Maybe, once profit reliably exceeds roughly $80,000 to $100,000. An S-corp splits income between salary and distributions, and only the salary carries payroll tax — the savings come from the SE-tax side, not Kansas. Below that threshold, payroll costs and extra filings usually consume the benefit. Model both structures with real numbers before electing.
What is the Kansas standard deduction?
Kansas sets its own standard deduction, raised as part of the 2024 tax restructuring, and it is more generous than it used to be. Most freelancers take it rather than itemising. The practical effect is that the first chunk of your income is shielded at the state level, which is why the effective state rate comes out below the headline brackets.
What happens if I skip Kansas and only file federally?
Kansas matches federal return data, so a Schedule C with no Kansas return gets flagged. You will owe the tax plus interest and penalties, and the state's collection process is not gentle. File both every year — the state return takes an hour once the federal one exists.
When are Kansas self-employed taxes due?
Quarterly estimates — federal and Kansas — are due April 15, June 15, September 15 and January 15. Annual returns are due April 15. Mark all eight dates in January, automate the transfers, and treat the payments as rent you owe yourself.
