How to Hire Employees in Mississippi: The Complete Compliance Sequence

The first Mississippi employer I walked through a first hire got the visible part right and the invisible part wrong. Signed offer letter, agreed start date, payroll software ready to run.

What this employer did not have was an E-Verify account, because every guide he had read described E-Verify as something federal contractors worry about. In Mississippi it is something every employer is required to do. This guide covers that step and every other one a first hire sets off, in the order you will do them.

The missed E-Verify account fits a pattern in this state. Mississippi is genuinely light on employer mandates. No state minimum wage. No state paid sick leave. No state meal or rest break rule. No local wage or leave ordinances stacked on top, because the legislature took that option away from cities. And then two obligations that are stricter or stranger than the national norm: mandatory E-Verify for everyone, and a workers compensation rule that turns on a headcount threshold instead of the first employee.

I built FirstHR because this is exactly the kind of sequence a business without a dedicated HR person keeps dropping. The rules are learnable in an afternoon. The reminder is what never gets set. Each step below carries its deadline and its exposure, checked against the agency or the statute that governs it.

The Mississippi Hiring Sequence at a Glance

Every item below except the onboarding plan is a legal obligation with a named enforcing body and a stated consequence. Four of them land before the first day of work, three cluster around the offer and the start date, and the rest fall inside the first month of employment.

The rest of this guide walks each step in the same order, calling out where Mississippi departs from the generic advice in a national guide to hiring your first employee.

Step 1: Get Your Federal Employer Identification Number

Start with the federal Employer Identification Number, because the MDES registration form opens with it, and the Department of Revenue requires it from every business entity other than a sole proprietorship. The EIN is how the IRS identifies your business on employment tax returns and deposits, and it is the number a workers compensation carrier will want on the application.

If you formed an LLC or a corporation and already hold an EIN, reuse it. If you have been operating as a sole proprietor and filing under your Social Security number, you need one now. Apply through the IRS online application and the number is issued at the end of the session.

IRS Publication 15 tells employers not to use a Social Security number in place of an EIN on employment tax returns, and the MDES account you open in Step 3 asks for that same federal number.

Set aside ten minutes and finish this before touching anything else. Founders who try to run the state registrations in parallel almost always restart one of them, because the portals ask for the federal number early rather than at the end. Getting the EIN first removes a dependency from the next three steps at once.

Step 2: Open Your Mississippi Withholding Account

Mississippi has a state income tax, so the second step is registering with the Department of Revenue for withholding. Registration runs through the Taxpayer Access Point, the online system the department uses for encrypted registrations, returns, and payments. Details and the registration entry point are published on the Department of Revenue withholding tax pages.

Have three things ready before you start: the federal identification number for the entity, contact details for whoever will prepare and file the returns, and an email address that will receive department notices. Gathering those first keeps the registration to one sitting instead of two.

Do this before the first payroll rather than after it. Withholding is a trust obligation. The money you deduct belongs to the state from the moment it leaves the paycheck, and late remittance carries penalty and interest even when the underlying calculation was correct.

Two operating details save trouble later. Withholding returns are due on the fifteenth day of the month following the period, so the due date is not the month end that most payroll calendars default to. And W-2s are due to employees and to the department by January 31, with electronic submission required of any employer issuing ten or more of them.

The table below puts every account in this sequence side by side, including the ones the next steps cover, so you can see which agency issues what and where you register.

Step 3: Open Your Unemployment Insurance Account with MDES

Unemployment insurance is a separate registration at a separate agency. You register with the Mississippi Department of Employment Security, and the MDES employer registration page routes a new business to the online tax registration system. The employer account number you receive is used on every quarterly wage report you file. Quarterly reports and payments are due by the last day of the month following each quarter.

Liability is defined by statute rather than by choice. A commercial employer becomes liable on paying $1,500 or more in wages in a calendar quarter, or on having at least one worker perform services in some portion of a day in each of 20 different calendar weeks in a calendar year. Agricultural and non-profit employers have their own tests, and a domestic employer becomes liable at $1,000 in a calendar quarter.

New employers do not choose their unemployment contribution rate. MDES applies a stepped entry schedule of 1.00 percent in the first year of liability, 1.10 percent in the second, and 1.20 percent in the third and later years until the employer becomes eligible for a modified rate based on its own experience.

The entry rates exclude the separate Workforce Investment and Training contribution that may apply in a given rate year. MDES charges contributions on the first $14,000 of wages paid to each employee in a calendar year.

That wage base changes how the cost behaves across a year. Because contributions stop once an employee crosses $14,000, unemployment tax is front-loaded into the early months for a salaried hire and spread across more of the year for a part-time one. Founders who budget it as a flat percentage of annual payroll consistently overstate the second half and understate the first quarter.

Step 4: Settle the Workers Compensation Question Before the Start Date

Mississippi requires workers compensation insurance once an employer regularly has five or more workers in the same business, and treats coverage as elective below that count. That threshold is the single most misunderstood rule in the state, because most states attach the obligation to the first employee and most national checklists are written that way.

The statute counts workmen or operatives employed regularly in the same business, not full-time equivalents, so a business that runs a small core team and adds summer help can cross the line without anyone noticing. That is the version of this problem I see most often.

The Mississippi Workers Compensation Commission administers the requirement and, under Miss. Code Ann. section 71-3-83, may assess a civil penalty determined case by case up to $10,000 against an employer that fails to secure the payment of compensation.

Below the threshold, elective does not mean advisable. If you carry no policy and an employee is hurt, the medical bill and the lost wages come out of the business rather than out of a carrier.

Coverage is priced on payroll and on the classification code that describes the work, which means a warehouse role and a desk role at the same salary do not cost the same to insure. Get the quote during the offer stage so the true cost of the hire is on the table before you commit to a number.

What worked for me

What I now tell every Mississippi founder: put a headcount check on the same recurring calendar entry as the quarterly unemployment filing. The workers compensation threshold is the only obligation in this sequence that arrives quietly, without a form, a portal, or a deadline notice. Nobody emails you when your fifth worker starts. The quarterly wage report is the one moment you are already counting heads, so it is the natural place to catch it.

Step 5: Set the Wage and the Pay Calendar Before the Offer

Mississippi has no state minimum wage, so the federal rate of $7.25 per hour governs covered employment and no city can raise it.

Miss. Code Ann. section 17-1-51 is the reason: it prohibits a county or municipality from establishing a mandatory minimum living wage rate or a minimum number of paid or unpaid vacation or sick days that would regulate how a private employer pays its employees. That removes the local wage and leave check that consumes real time in other states.

Pay frequency is mostly left to you as well. Miss. Code Ann. section 71-1-35 reaches manufacturers employing as many as 50 or more employees and employing public labor, plus public service corporations, and requires them to pay at least once every two weeks or twice each calendar month, or on the second and fourth Saturday. Outside that group there is no state interval rule, so the payday you write into the offer letter is the governing one.

Overtime is federal. Mississippi has no state overtime statute, no state meal or rest break requirement for adults, and no state pay transparency law, so the Fair Labor Standards Act does the work on hours and the exempt classification analysis. Get the exempt or non-exempt call right before the offer, because rewriting it later means recalculating hours you never tracked.

Separation pay is worth deciding now too. Mississippi sets no statutory deadline for a final paycheck, which in practice means the next regular payday, and it does not require payout of unused vacation unless your own written policy or a contract promises it. Both of those are policy choices you make once, in the employee handbook, rather than decisions you improvise during a termination.

Step 6: Complete Form I-9 by the Third Business Day

Every employer in the United States must complete Form I-9 for every new hire to verify identity and authorization to work. Mississippi adds a second layer on top of it, covered in the next step, which makes getting the I-9 itself right more consequential here than in most states.

The employee completes Section 1 no later than the first day of work. You complete Section 2 within three business days of the start date by examining original documents the employee chooses to present.

You cannot tell the employee which documents to bring. Specifying documents is its own violation, separate from any deadline problem, and it can turn an otherwise clean file into a discrimination claim.

Use the current edition. USCIS publishes Form I-9 with an edition date of 01/20/25 and an expiration date of 05/31/2027, and the deadline for moving electronic I-9 systems onto a version carrying that expiration date has already passed. The edition date sits at the bottom of the form and the expiration date at the top, so check both on the PDF in your onboarding packet before the next hire signs it.

Step 7: Run the New Hire Through E-Verify

Mississippi requires every employer to use E-Verify, not just public contractors, and this is the step out-of-state founders miss. The Mississippi Employment Protection Act, at Miss. Code Ann. section 71-11-3, provides that every employer shall register with and use the status verification system to verify the federal employment authorization status of all newly hired employees.

The requirement phased in by employer size. State agencies, public contractors, and the largest private employers were covered from July 1, 2008, with successive tiers following, and the final phase covering all remaining employers took effect on July 1, 2011. There is no size exemption left to rely on. A separate provision of the same act also carries penalties against public contractors and subcontractors who fail to participate.

E-Verify is a federal system that compares the information on a completed I-9 against government records. Enrolling never replaces the I-9 itself, and the sequence matters: complete the I-9 first, then create the case. Under federal program rules the case is created no later than the third business day after the employee starts work for pay, which lines the two deadlines up neatly if you handle them together.

The penalty structure is what makes this worth a calendar entry rather than a mental note. An employer violating the section is subject to cancellation of any state or public contract, resulting in ineligibility for state or public contracts for up to three years, and to the loss of any license, permit, or certificate for up to one year.

For a licensed trade, a contractor, or anyone who sells to a public body, losing a license or a public contract is a business-continuity risk rather than a fine.

Step 8: Collect Form W-4 and Form 89-350 Before the First Paycheck

A Mississippi new hire completes two withholding forms, not one. Federal Form W-4 sets federal withholding. Mississippi Form 89-350, the employee withholding exemption certificate, sets state withholding, and the Department of Revenue expects it on file for each employee so the exemption amount used in the tables is documented.

The state calculation does not apply a single percentage to the whole wage. The Department of Revenue exempts the first $10,000 of taxable income and taxes the excess at 3.75 percent from tax year 2027 (4 percent for 2026, the last step of the Mississippi Tax Freedom Act of 2022).

The Build Up Mississippi Act (House Bill 1, 2025 regular session) set that 2027 rate and steps it down to 3.5 percent for 2028, 3.25 percent for 2029, and 3 percent from 2030. That moving rate is the reason to pull the current withholding tables each January instead of reusing the prior settings.

Collect both forms before day one rather than on day one. In the table below, Section 1 of the I-9, Form W-4, Form 89-350, and the direct deposit authorization can all be finished before the first day, which turns the first morning into an introduction to the work instead of an hour of paperwork. That sequencing is the whole point of structured new hire paperwork.

Step 9: File the New Hire Report Within Fifteen Days

Mississippi gives you 15 days from the date of hire, rehire, or return to work to report a new employee. Miss. Code Ann. section 43-19-46 sets that deadline with no business-day carve-out, so count calendar days. The filing goes to the Mississippi State Directory of New Hires, which operates under the Department of Human Services as part of child support enforcement.

The report is short. It carries the employee name, address, Social Security number, and date of birth; your business name and address and your federal and state withholding tax identification numbers; and the date the employee began, resumed, or is scheduled to begin work.

Mississippi accepts a copy of the employee W-4 or its equivalent as the report, which is why filing it alongside the withholding forms takes almost no extra time.

Rehires count. If a former employee returns after at least 60 consecutive days of separation, layoff, furlough, or leave without pay, that return is reportable the same way an original hire is. Employers who run seasonal crews miss this more often than they miss the original filing, because the person is already in the payroll system and feels like an existing employee.

The penalty is modest compared with the other penalties in this sequence. The civil penalty runs up to $25 per newly hired employee, and up to $500 where the failure is the result of a conspiracy between employer and employee to withhold the report or to supply a false or incomplete one.

Step 10: Post the Notices and Onboard Through Day 90

Two state notices and the federal poster set have to be displayed where employees can see them before anyone starts work. Mississippi requires the Unemployment Insurance poster, which MDES provides at no charge in English and Spanish, and the Mississippi Workers Compensation notice, which the Commission publishes.

The federal set adds the FLSA minimum wage poster, the OSHA job safety notice, and the polygraph protection notice, plus notices that attach at federal size thresholds, such as the equal employment opportunity (EEO) notice at 15 or more employees.

Do not pay a vendor for posters you can download for free from the agencies that publish them. The one thing worth paying attention to is placement: the requirement is a conspicuous location accessible to all employees, which for a distributed team means an internal page every employee can reach rather than a wall nobody visits.

Compliance gets the employee legally onto payroll. Onboarding is what makes the hire worth making. Research reported by SHRM (2017) shows that up to 20 percent of employee turnover happens within the first 45 days of employment, which means the onboarding window is where the hiring investment either pays off or evaporates. Finish as much of the sequence as you can before day one, so the first day is about the work.

The AI onboarding wizard in FirstHR exists to run this whole packet without a dedicated HR person. The offer letter goes out with built-in e-signature, the fifteen-day new hire report becomes a task rather than a memory, and a 30-60-90 day plan is generated from the job description. Flat, predictable pricing, with no per-employee fee.

Form I-9, the W-4, and Form 89-350 go on the new hire's first-day list as tasks, and completed forms are kept in their employee file. The forms themselves are completed outside the platform.

Mississippi-Specific Rules Every Employer Should Know

Mississippi employment law is thin by design, and that cuts both ways. There is very little state regulation to comply with, and very little state protection to rely on, which means federal law and your own written policies do almost all the work. These are the differences that change what you write in a handbook and how you handle a first hire.

The item founders underestimate most is the absence of a state discrimination statute. Mississippi has no general state equivalent of Title VII, the Americans with Disabilities Act (ADA), or the Age Discrimination in Employment Act (ADEA) covering private employment, and no state agency that investigates private-sector discrimination complaints.

Charges go to the federal Equal Employment Opportunity Commission (EEOC), and the federal size thresholds decide what applies to you: Title VII and the ADA at 15 or more employees, the ADEA at 20 or more, and the Family and Medical Leave Act (FMLA) at 50 or more.

Mississippi is also a right-to-work state, written into the state constitution, so union membership or non-membership cannot be a condition of employment. And employment is at will with narrow exceptions, which is why a handbook that carefully preserves at-will status is worth more here than a handbook full of policies the state never asked for.

Medical cannabis is worth spelling out. The Mississippi Medical Cannabis Act expressly leaves employer drug testing policies intact, does not require an employer to permit or accommodate medical use or to modify a job, and does not prohibit refusing to hire or taking adverse action based in whole or in part on medical cannabis use by an individual, regardless of impairment.

The Mississippi approach is unusually employer-friendly, and it still does not displace federal disability law where an underlying medical condition is involved.

City and County Requirements in Mississippi

No Mississippi city or county can set its own minimum wage or leave mandate for private employers, because the legislature took that authority away. The stated rationale is a uniform business environment and the avoidance of inconsistent requirements from jurisdiction to jurisdiction.

Miss. Code Ann. section 17-1-51 does this by barring counties, boards of supervisors, municipalities, and municipal governing authorities from establishing a mandatory minimum living wage rate or a minimum number of paid or unpaid vacation or sick days regulating how a private employer pays its employees.

What cities do require is a business privilege license. Each city runs its own privilege license process, so the fee, the renewal date, and the application route vary by jurisdiction. Jackson, for example, takes applications through its Business Licensing Division and requires renewal every year.

A privilege license is a business-registration obligation rather than an employment one, but it belongs on the same setup checklist because it is easy to overlook when the entity was formed at the state level.

One practical consequence: if you hire across several Mississippi cities, your pay and leave policies do not need to vary by location. That is unusual, and it is worth taking advantage of. Write one handbook, one pay policy, and one background check process for the whole state instead of maintaining local variants.

Employee vs Independent Contractor in Mississippi

Misclassifying an employee as an independent contractor is the most expensive avoidable mistake available to a Mississippi small business, because a single wrong call triggers three separate exposures at once. MDES can reclassify the worker and assess unpaid unemployment contributions with interest and penalties, the IRS can assess federal employment taxes, and the workers compensation analysis changes for the same period.

The test is about control, not paperwork. A signed contractor agreement does not decide the question, and neither does a worker's preference for a 1099. What decides it is whether you direct how the work is done or only what result is delivered, the question at the heart of the common-law control test.

Two Mississippi-specific notes. Contractors are outside the state new hire reporting mandate, unlike in some states that require contractor reporting, so a misclassified worker is invisible to the state directory until something else surfaces the relationship. And E-Verify applies to employees, so a misclassification also means a missing statutory verification for a person who was legally an employee the whole time. When the answer is arguable, hire the person as an employee.

The Mistakes That Cost Mississippi Employers the Most

These are the errors I see repeatedly at Mississippi small businesses. Each one is preventable with a process or a reminder rather than with legal knowledge, and each one is expensive relative to the effort of avoiding it.

Most of these failures come down to timing, not knowledge. The employer knows the I-9 has to be done. It just did not get done by the third business day. Compliance at this size fails when the founder gets busy, which is why an automated reminder is worth more than a compliance manual nobody opens twice.

What worked for me

The habit that fixed this for the employers I work with: one packet, one sitting. On the day the offer is accepted, send the I-9, the W-4, and Form 89-350 together, and put three tasks on the calendar at the same moment. Day three for I-9 Section 2 and the E-Verify case. Day fifteen for the new hire report. Quarter end for the headcount check against the workers compensation threshold. Nothing in this sequence is hard. All of it is forgettable.

Here is that sequence as one sheet: the accounts you open once, the per-hire deadlines with the date each one closed written beside it, and the quarterly check that catches the workers compensation threshold before it catches you.
