How to Hire Employees in Kansas: The Complete First-Hire Compliance Sequence

The first person I put on payroll in Kansas cost me two weeks of evenings before the offer letter ever went out. Not because the rules are hard. Because they live in four unrelated places: the IRS, the Kansas Department of Revenue, the Kansas Department of Labor, and a private insurance carrier that has nothing to do with the other three. Nobody hands you the order.

Kansas sits in the middle of the compliance spectrum: nothing like California, but not Texas either. There is a state income tax, so there is a state withholding certificate with its own deadline. Workers compensation is mandatory above a payroll floor rather than optional. And the new hire statute counts business days, not calendar days, a detail out-of-state checklists often miss.

This guide hands you that order: nine steps, each deadline tied to the Kansas statute or the agency that enforces it, in the sequence the work actually happens. I built FirstHR because a founder should not need a payroll background to keep track of a three-business-day form and a twenty-business-day filing at the same time.

Every Kansas Hiring Deadline in One Place

Kansas hiring involves three government relationships and one private one. The IRS issues your employer identification number (EIN), the Department of Revenue owns withholding, the Department of Labor owns unemployment insurance and new hire reporting, and workers compensation is bought on the open market because Kansas has no state fund.

Here is the full timeline before we walk through each step. Every deadline below is enforceable, and the ones with dollar amounts attached are the ones worth building a reminder around. Statute citations use K.S.A., short for Kansas Statutes Annotated.

Two of these are Kansas-specific in a way that catches employers who have hired elsewhere: there is a second withholding certificate, Form K-4, that belongs in the hire-date packet rather than the first-payroll packet, and the new hire statute counts business days. Everything else follows a familiar federal shape.

Step 1: Get Your Federal Employer Identification Number

Start with the EIN, because both Kansas registrations ask for it on the first screen. The Employer Identification Number is how the IRS identifies your business on payroll returns, and you cannot substitute a Social Security number once you have employees.

Apply online through the IRS EIN application. The application is free, it has to be finished in one session, and the number is issued at the end of it. If you already got an EIN when you formed the entity, reuse it. If you have been operating as a sole proprietor filing under your own Social Security number, you need one now.

One sequencing note that saves a week: do the EIN first thing in the morning of the day you decide to hire, not the week of the start date. The Kansas registrations that follow are faster when the number is already in hand.

Step 2: Register for Kansas Withholding Tax

Kansas taxes wage income, so you must register with the Kansas Department of Revenue for a withholding tax account before the first Kansas payroll. Registration runs through the Business Tax Application, Form CR-16, which opens accounts for withholding along with any other state-administered taxes your business owes.

The application asks for the business name, ownership structure, address, contact details, and your EIN. Your annual Kansas withholding amount also matters, because it determines how often you remit. Withholding is deposited on Form KW-5 and reconciled once a year on Form KW-3, and each employee receives a federal W-2 that reports Kansas wages and Kansas tax withheld.

Kansas withholding runs on a two-bracket income tax schedule of 5.20 percent and 5.58 percent under Senate Bill 1 from the 2024 special session. There is no local or municipal income tax on wages anywhere in the state, which means every Kansas employer files with the same single revenue agency regardless of whether staff sit in Wichita, Topeka, or Overland Park.

Step 3: Open a Kansas Unemployment Tax Account

The Kansas Department of Labor administers unemployment insurance, and it is a separate registration from the Department of Revenue account you just opened. Under K.S.A. 44-703 you become a liable employer, meaning the unemployment tax applies to you, once you pay $1,500 or more in wages in any calendar quarter of the current or preceding calendar year.

You also become liable once you have at least one individual in employment for some portion of a day in each of 20 different calendar weeks in the current or preceding year. Read that carefully, because a single part-time hire clears this second test inside five months.

Most employers registering for a first employee will meet one threshold or the other in the first quarter, so registering proactively is cheaper than backfilling contribution reports later.

Unemployment insurance in Kansas is funded entirely by the employer. Nothing is withheld from employee wages. Under K.S.A. 44-710a a new employer pays 1.75 percent, or 5.55 percent if the business is classified in the construction industry, until it has enough history for its own rate.

The taxable wage base moved off a flat number. K.S.A. 44-703 fixed it at $14,000 per employee for calendar years 2016 through 2025, then replaced that with a formula: 25 percent of the statewide average annual wage from the previous year, rounded to the nearest $100, for 2026 and 2027.

That percentage steps to 30 percent in 2028, 35 percent in 2029, and 40 percent from 2030, with a possible rise to 45 percent after 2031. For 2026 the taxable wage base is $15,100, according to the US Department of Labor (January 2026).

The Kansas Department of Labor delivers your current wage base in the annual rate letter in your employer portal. Reports are filed quarterly, and your experience rating replaces the new employer rate once you qualify.

Step 4: Verify Work Authorization with Form I-9

Every employer in the United States must complete Form I-9 for every new hire, and Kansas adds nothing to the federal requirement. The form has two halves with two different deadlines, and the second one is the one that gets missed.

Section 1 belongs to the employee and is due on or before the first day of work. The employee provides identifying information and attests to citizenship or work authorization status. Section 2 belongs to you and is due by the end of the third business day after employment begins. You examine the original documents the employee presents, record what you saw, and sign.

You cannot tell the employee which documents to bring. The list of acceptable choices is theirs, and steering it is itself a violation.

E-Verify is a separate system, and Kansas does not require private employers to use it. Enrollment is voluntary unless a federal contract brings you under the federal acquisition regulation clause, and it never replaces the I-9.

Step 5: Collect the Federal W-4 and the Kansas K-4

Kansas is a two-form state. The federal W-4 sets federal income tax withholding and is due before the first paycheck. The Kansas Employee Withholding Allowance Certificate, Form K-4, sets state withholding, and the Department of Revenue withholding guide says every employee must furnish a signed K-4 and should complete it as soon as they are hired or taxable payments begin.

That second form is the trap. Founders who have hired in a no-income-tax state think of tax forms as a first-payroll item, and in Kansas one of them belongs with the hire paperwork. If no K-4 arrives, you must withhold Kansas tax at the single rate with no allowances, which over-withholds and produces a frustrating conversation in week two.

Employees should file a fresh K-4 whenever marital status or the number of exemptions changes. Build that into your annual reminder cycle alongside address and beneficiary updates rather than waiting for someone to ask.

What worked for me

I stopped treating tax forms as separate errands and folded them into one pre-start packet: offer letter, handbook acknowledgment, W-4, K-4, direct deposit authorization, and I-9 Section 1. All of it goes out the day the offer is accepted, with e-signature on the offer letter and the handbook acknowledgment. By the time Day 1 arrives, the only open item is Section 2 of the I-9, which needs the employee physically present anyway. The new hire paperwork stops being a scramble the moment it becomes one packet instead of six.

Step 6: File the Kansas New Hire Report Within 20 Business Days

Kansas requires every employer and labor organization doing business in the state to report each newly hired employee to the secretary of labor within 20 business days. K.S.A. 75-5743 sets the clock running from the hiring, rehiring, or return to work, or from the date the employee first receives wages or other compensation, whichever applies.

The statute counts business days, not calendar days, which runs the other way from most states. The Department of Labor's own new hire page simply says 20 days, so a report filed within 20 calendar days satisfies both readings.

The report goes to the Kansas Department of Labor new hire directory. You submit the employee name, address, and Social Security number, the date services for remuneration (pay) were first performed, and your business name, address, and federal tax identification number.

A newly hired employee for this purpose means someone who has not previously worked for you, or who worked for you before but has been separated for at least 60 consecutive days. That 60-day rule is what makes seasonal rehires reportable.

Step 7: Secure Workers Compensation Coverage

Kansas requires workers compensation coverage for nearly every employer, and the exemption is narrower than most founders assume. Under K.S.A. 44-505, the workers compensation act applies to all employments in the state except a short list.

One item on that list is an employer whose total gross annual payroll for the preceding calendar year was not more than $20,000 for all employees and who reasonably estimates the current year will also stay at or below $20,000. One full-time hire at a normal wage clears $20,000 on its own.

The floor exists for very small operations, not for a business making its first real hire. Agricultural pursuits are separately exempt unless the employer is the state or a state agency.

The Kansas Department of Labor explains the computation this way: count all wages paid to all workers, including wages paid for work performed outside Kansas. Wages paid to a member of the owner's family by marriage or blood normally drop out of the total, but that exclusion does not apply to a business structured as a corporation. A corporate employer counts everyone.

How Coverage Is Purchased

Kansas has no state insurance fund. K.S.A. 44-532 gives you three routes: insure with a carrier authorized to write workers compensation business in Kansas, qualify as a self-insurer by demonstrating the financial ability to pay claims directly, or maintain membership in a qualified group-funded workers compensation pool. The employer pays the full cost. Nothing comes out of employee wages.

Bind the policy before the start date, not after the first quarter closes. Carriers underwrite off payroll estimates and job classifications, so have your wage plan and a plain description of the work ready when you call.

Step 8: Post the Required State and Federal Notices

Kansas and federal law both require specific notices displayed where employees can read them, and they have to be up before anyone starts work. Physical posting is the default for on-site staff. Remote employees need an electronic equivalent they can actually reach.

All of these are free downloads from the issuing agency. Kansas posters come from the Department of Labor and the Human Rights Commission, federal posters from the US Department of Labor, the Occupational Safety and Health Administration (OSHA), and the Equal Employment Opportunity Commission (EEOC). There is a whole cottage industry selling laminated all-in-one panels, and none of it is required.

If you employ anyone under 16, read the hour limits before scheduling. K.S.A. 38-603 prohibits employing a child under 16 before 7 a.m. or after 10 p.m. except on an evening that does not precede a school day, and caps the schedule at eight hours in a calendar day and 40 hours in a week. Federal child labor rules apply on top of that, and the stricter provision governs.

Steps 1 through 8 produce two things worth writing down in one place: a short list of account numbers you will never set up again, and a handful of dates that only exist once a start date does. The record below holds both. Fill in Part 1 once, then copy Part 2 for every hire and convert the two business-day deadlines into calendar dates the day the start date is agreed.

Step 9: Onboard From Day 1 Through Day 90

Compliance gets someone legally onto payroll. Onboarding is what turns them into a contributor, and it is the step with no fine attached, so it gets cut first.

The window that decides whether a hire sticks is short, and it closes long before the first anniversary. That is why the money you just spent on recruiting is effectively bet in the first quarter of employment.

The practical goal is to finish every form you can before Day 1 so the first day belongs to the work. That is achievable in Kansas: only Section 2 of the I-9 genuinely requires the employee in front of you.

This is the part of the sequence FirstHR was built for. The offer goes out with e-signature, and the Kansas deadlines become tasks with due dates instead of things you hope to remember. Form I-9, the W-4, and the K-4 go on the new hire's first-day list as tasks, and the completed forms are kept in their employee file; the forms themselves are completed outside the platform.

The AI onboarding wizard turns the job description into a 30-60-90 day plan rather than leaving the manager to invent one. Pricing is flat and predictable, with no per-employee fee that punishes you for hiring the second person.

Kansas Employment Rules That Change How You Write Policy

Beyond the hiring sequence itself, a handful of Kansas rules shape what belongs in your employee handbook and how you handle pay and separation. These are the ones that differ enough from neighboring states to matter.

Kansas is an at-will state, with the usual public policy and implied contract exceptions recognized by its courts. Handbook language that promises progressive discipline or describes employment in terms of permanence can undercut that, which is why an explicit at-will statement belongs near the front of the document rather than buried in an appendix.

Kansas is also a right-to-work state under its constitution, so union membership and dues cannot be made a condition of employment.

The overtime line deserves a note, because it reads stranger than it behaves. K.S.A. 44-1204 sets a 46-hour weekly overtime threshold but expressly excludes employees covered by section 7 of the Fair Labor Standards Act. Most Kansas employers are FLSA-covered, so the practical threshold is 40 hours and the 46-hour rule applies to almost nobody.

Classify people correctly first, using the federal exempt and non-exempt tests, and the state number rarely enters the picture.

What worked for me

The Kansas detail that changed my process was the final paycheck rule. K.S.A. 44-315 puts final wages on the next regular payday for both quits and discharges, which is more forgiving than states that demand same-day payment on termination. That forgiveness made me sloppy until I read the penalty clause: willful failure runs one percent of unpaid wages per day after an eight-day grace period. Now the termination checklist and the final paycheck calculation are the same task, closed together.

City and Metro Rules for Kansas Employers

Kansas cities have far less room to add employment obligations than cities in most states, because K.S.A. 12-16,130 preempts the entire category. No city, county, or local government unit may enact or administer an ordinance requiring an employer to provide leave, pay compensation for leave, pay wages above the state minimum, offer non-mandated benefits, or alter employee scheduling, unless state or federal law requires it.

The preemption has one carve-out, for economic development incentive programs. The practical consequence: there is no Kansas equivalent of a city paid sick leave ordinance or a local minimum wage. Statewide, Kansas has no paid sick leave mandate and no state meal or rest break requirement either, so what you offer is a retention decision rather than a compliance one.

What cities can still do is legislate on discrimination, which sits outside the preemption. Wichita, for example, maintains a local non-discrimination ordinance covering employment on a broader list of protected characteristics than state law, including sexual orientation and gender identity. Several other Kansas municipalities have adopted comparable ordinances, Lawrence among them. Check the city clerk site for each place you actually employ people.

The Kansas City metro is the trap worth naming. The state line runs through the middle of it, and a Johnson County employer who hires someone living and working on the Missouri side picks up a Missouri withholding registration, a Missouri unemployment account, and potentially the Kansas City earnings tax in one move. Where the employee performs the work governs, not where your office sits.

Employee or Independent Contractor: Get This Right Before the Offer

Misclassifying a worker as an independent contractor is the most expensive avoidable mistake in this entire guide, because it is not one exposure but four. Federal employment taxes, Kansas withholding, Kansas unemployment contributions, and workers compensation coverage each rest on the classification, and each agency reaches its own conclusion on its own timetable.

The test that matters is the common-law control test: does the hiring party control how the work is done, or only what result is delivered? The label on the agreement is not evidence. The behavior is.

If most of your answers land in the left column, you have an employee, and the nine steps above apply in full. When the answer is genuinely mixed, classify as an employee. A reclassification finding costs back taxes, penalties, and interest across multiple agencies, while employing someone properly costs the employer share of payroll taxes and a workers compensation premium. The second number is always smaller.

The Mistakes That Cost Kansas Employers the Most

These are the failures I see repeatedly, and nearly all of them are a timing or sequencing problem rather than a knowledge problem. The founder knows the I-9 exists. It just did not get finished by the third business day.

The common thread is that compliance breaks when the calendar gets busy, not when the rules are unclear. That is an argument for automated reminders and a written sequence, not for more reading. Every item above can be reduced to a task with a due date attached to the start date.
