Mississippi Payroll: Employer Tax and Software Guide

Mississippi is one of the easiest states in the country to run payroll in, and that is exactly why employers here get caught out. There is no local income tax, no occupational tax, no state disability program, no paid family leave contribution, and no state minimum wage statute at all. The unemployment wage base is $14,000 per employee, and unemployment is the only state payroll tax the employer pays out of its own pocket. On paper the whole obligation fits on an index card.

Then you meet the details that a light-touch state leaves to you. The state income tax rate is falling on a legislated schedule, so the number in your software this year is not the number from last year. The federal W-4 does not satisfy Mississippi withholding, and an employee who never signs the state form gets withheld at zero exemption. There is no statutory deadline for a final paycheck, which sounds like relief until a former employee asks when they are getting paid and nobody can point to a rule.

This guide covers what Mississippi requires from employers as of August 2026, the obligations that state tax registration does not cover, and how 10 payroll providers price the work at 10, 25, and 50 employees.

What Mississippi requires from employers

Two state obligations sit on top of federal payroll, and they belong to two different agencies with no combined registration between them: income tax withholding at the Department of Revenue, and unemployment contributions at the Department of Employment Security.

State income tax withholding on a falling rate

Mississippi taxes wage income, and the structure is a two-step schedule rather than a true flat tax. According to the Mississippi Department of Revenue, the first $10,000 of taxable income is taxed at 0 percent and the balance above $10,000 is taxed at a single rate. That rate is 4 percent for tax year 2026, down from 4.4 percent for 2025, and 3.75 percent is already legislated for 2027.

The direction of travel matters more than any single year. The Build Up Mississippi Act, approved by the governor in March 2025, sets 3.5 percent for 2028, 3.25 percent for 2029, and 3 percent for 2030 and every year after, then makes any further reduction from 2031 conditional on the state reserve fund being fully funded and general fund collections clearing a revenue threshold. For a payroll administrator that means the state rate is a moving figure that changes every January, and a platform that quietly carries last year's table over-withholds every employee until someone notices.

How the Mississippi withholding calculation works

Mississippi does not compute withholding from a percentage of gross, and it does not reuse the federal withholding calculation either. It uses wage bracket tables in Publication 89-700 that combine three inputs: the payroll period, the exemption amount the employee claims on Form 89-350, and the standard deduction for the filing status. The result is the amount withheld per pay period.

A married couple can split the $12,000 joint exemption between them in multiples of $500 in any way they choose, so long as the combined total does not exceed $12,000, and they can divide dependents the same way. That flexibility is useful for two-earner households and it is also the single most common source of over-claiming, because both spouses claim the full amount on separate certificates. Supplemental wages such as bonuses and commissions are added to regular wages for the period and withheld as one payment.

Deposit schedules and returns

The Department of Revenue assigns each employer a monthly or quarterly filing frequency rather than letting the employer pick one. Returns are due on the fifteenth day of the month following the period, and a return is required for every period even when nothing was withheld.

Employers issuing ten or more W-2s must file them electronically through Taxpayer Access Point, and the Department of Revenue applies a penalty of $25 for the first instance of non-compliance and $500 for each additional instance. Bulk filing through the federal and state employment tax program is available if your provider participates, in which case the returns and payments transmit without anyone touching the state portal. Late filing or payment carries a standard 10 percent penalty, and interest accrues on delinquent tax at one half of one percent per month.

Unemployment insurance contributions

Unemployment insurance is an employer-only cost in Mississippi, with nothing withheld from the employee. The taxable wage base is $14,000 per employee per year, printed on the quarterly contribution report itself, Form UI-2/3, and the instructions apply it to the first $14,000 paid by each employer in a calendar year, which means a mid-year job change restarts the count at the new employer.

According to the Mississippi Department of Employment Security, a start-up pays 1.00 percent in the first year of liability, 1.10 percent in the second, and 1.20 percent in the third and subsequent years until the account qualifies for a modified rate. Those figures exclude the Workforce Investment and Training contribution rate that may apply in a given rate year, so the number on your rate notice can be slightly higher than the headline. An employer acquiring a business already liable in Mississippi may inherit a modified rate immediately.

Liability itself begins earlier than many owners expect. A commercial enterprise becomes liable on payment of $1,500 in wages in a calendar quarter, or when at least one worker performs services in some portion of a day in each of 20 different calendar weeks in a year. Domestic employers cross at $1,000 in a quarter, agricultural employers at $20,000 in a quarter or ten workers across 20 weeks, and 501(c)(3) organizations at four workers across 20 weeks.

Registration, new hire reporting, and coverage

There is no single-window registration in Mississippi. Withholding registration runs through the Department of Revenue Taxpayer Access Point, which issues the employer withholding account number, and unemployment registration runs separately through the Department of Employment Security once liability is met. Workers compensation coverage becomes mandatory once an employer has five or more workers regularly in the same business, under Mississippi Code Section 71-3-5.

New hire reports go to the Mississippi State Directory of New Hires at the Department of Human Services within 15 days of the hire date, five days tighter than the federal baseline. Rehires count too: anyone returning after being laid off, furloughed, separated, granted a leave without pay, or terminated for at least 60 consecutive days has to be reported again, which is the part small employers most often miss. Electronic filers submit in two monthly transmissions 12 to 16 days apart.

The local layer that state registration does not cover

Mississippi has no local income tax, no occupational privilege tax, and no city payroll levy, so the local tax layer that complicates Colorado or New Jersey simply does not exist here. What state tax registration does not cover instead is a set of wage and hour rules that live outside both revenue agencies, and in Mississippi several of them are defined by what the state has chosen not to legislate.

The wage floor is federal, and no city can raise it

Mississippi has no state minimum wage statute, so the federal Fair Labor Standards Act rate of $7.25 per hour is the operative floor for covered nonexempt employees. Because there is no state rate, there is nothing to index and no scheduled increase to plan around. Mississippi Code Section 17-1-51 also prevents counties and municipalities from adopting a local or living wage that regulates private employers, so the number is identical statewide.

For tipped work this matters more than the headline number suggests. Mississippi has a large restaurant, casino, and coastal hospitality workforce running on the federal tip credit structure, where the employer pays a $2.13 cash wage and claims up to $5.12 in tips toward the federal minimum. The employer owes the difference in any workweek where cash plus tips falls short, which is a per-employee, per-week calculation rather than an annual reconciliation.

Pay frequency: the manufacturing rule almost nobody reads

Mississippi imposes a statutory pay frequency on two categories of employer and leaves everyone else to their own schedule. Under Mississippi Code Section 71-1-35, employers engaged in manufacturing who employ 50 or more employees and employ public labor, and public service corporations, must pay at least once every two weeks or twice during each calendar month.

The statute also fixes the lag: each payment must settle everything earned up to no more than ten days before the pay date, with fifteen days allowed for public service corporations. The section does not reach people employed in bona fide executive, administrative, or professional capacities. With manufacturing among the state's larger private employment sectors, a Mississippi plant crossing 50 employees can acquire a pay frequency obligation it did not have the month before, and a monthly payroll calendar becomes non-compliant overnight.

Every other Mississippi employer, which is most of them, sets pay frequency by policy or employment agreement. That is a genuine freedom and also a documentation duty: with no statute to point at, the payroll calendar in your handbook is the rule, and payroll records are what prove you followed it.

Final pay after a quit or a discharge

Mississippi has no statutory deadline for a final paycheck, and unlike most states the answer does not change between a resignation and a termination. There is no separate clock for a discharge, no penalty wage provision, and no state agency that adjudicates the timing.

In the absence of a state rule, the federal default governs: wages for the final period are due no later than the next regular payday for that period. Accrued vacation or paid time off is not payable unless a written policy, handbook, or contract promises it, which puts the burden of clarity on the employer's own documents rather than on the statute.

Coverage rules that begin at a headcount

Two thresholds are worth marking on the calendar. Workers compensation coverage becomes mandatory once five or more workers are regularly employed in the same business, with nonprofit charitable, fraternal, cultural, and religious organizations carved out, and with an exemption from insuring available on application to the Workers' Compensation Commission for employers that can show the financial ability to pay compensation themselves. Federal unpaid family and medical leave obligations arrive at 50 employees.

Between those two numbers Mississippi asks for very little: no state paid sick leave, no state disability insurance, no paid family leave contribution, and no state-mandated leave accrual to track. For payroll that is a genuinely short stack, and it is the reason the provider comparison below turns on price and service rather than on jurisdictional coverage.

It is worth seeing how thin that stack really is by comparison. A neighboring employer in Alabama handles occupational license taxes in several cities on top of state withholding, and a Georgia employer works from a different rate structure and a different unemployment wage base. Mississippi asks for two state filings and nothing municipal at all.

10 payroll providers for Mississippi employers compared

Every provider below files Mississippi withholding returns and MDES unemployment contributions. With no local taxes and no state leave programs to support, the differences that matter here are price, whether the platform collects Form 89-350 at onboarding rather than assuming a federal W-4 is enough, and what a hire across a neighboring state line costs.

OnPay

One plan at $49 per month plus $6 per employee, with every feature included and no tiers to climb. Tax filing covers all 50 states with no multi-state surcharge, and year-end W-2 and 1099 filing sits in the base price rather than being billed separately. For a Mississippi employer near Memphis or Mobile, that included multi-state handling is worth more than it looks, because the second-state question is the main thing that reorders pricing in a state this simple.

Gusto

The most common first payroll purchase for US small businesses. Tax filing is automatic, the interface is pleasant, and pricing is published. Simple runs $49 per month plus $6 per employee following a base increase in early 2026, and the onboarding flow collects state withholding certificates rather than leaving Form 89-350 to a paper folder.

The catch for Mississippi employers is that Simple covers single-state payroll only. One hire in Memphis, which is a 25-minute drive from DeSoto County, moves you to Plus at $80 plus $12 per employee. Mississippi is a heavy cross-border commuting state on three sides, so model the Plus number before you assume the Simple price.

Patriot Software

The cheapest legitimate full-service payroll available. Full Service is $37 per month plus $5 per employee and includes federal, state, and local tax filing plus new hire reporting, which covers the 15-day Mississippi report without a separate step. Basic is $17 plus $4 if you file taxes yourself.

Additional state filings cost $12 per month each, which is the one place the price stops being the cheapest. For a single-state Mississippi employer with a straightforward monthly withholding frequency, it is very hard to beat on cost.

Square Payroll

At $35 per month plus $6 per person, Square is the cheapest full-service option with published pricing, and the plan covers federal, state, and local tax calculation, payment, and filing. For a Gulf Coast restaurant or a Tupelo retailer already running Square point of sale, timecard and tip data flow into payroll with no integration work, and tip reporting is native rather than bolted on.

SurePayroll

Owned by Paychex and aimed at very small employers and household employers. Full Service is $29 per month plus $7 per employee, with a flat $9.99 monthly multi-state fee regardless of how many states are involved. For a Mississippi business with a few people across the Tennessee or Louisiana line, that flat structure beats per-state pricing.

QuickBooks Workforce Payroll

Formerly QuickBooks Payroll, now renamed. Core is $50 per month plus $6.50 per employee. The reason to pick it has always been the same: if your books already live in QuickBooks Online, payroll entries reach the general ledger without an export step. Per-employee pricing rose across all tiers in mid-2026.

ADP RUN

ADP processes payroll for roughly one in six American workers and has the deepest tax compliance engine in the category. In Mississippi the practical argument is the annual rate change: a state income tax rate that steps down every January reaches ADP's tables without anyone at your company tracking the legislature.

The cost is opacity. ADP does not publish RUN pricing; third-party estimates put Essential near $79 per month plus $4 per employee, but every quote is individual. Contracts typically run a year with automatic renewal and a 30 to 60 day cancellation window.

Paychex Flex

Paychex competes on service rather than software, and unusually among quote-driven vendors it publishes an entry rate: Essentials at $39 per month plus $5 per employee, with higher tiers quoted individually. In Mississippi the service model earns its keep when a Department of Revenue notice arrives or an MDES rate notice does not match what the software is charging.

Paylocity

Paylocity sits between small-business payroll and combined HR and payroll, aimed at companies that have outgrown basic payroll but do not want enterprise complexity. It publishes detailed per-state tax facts including Mississippi, and the HR module covers performance, learning, and engagement alongside payroll. Pricing is quote-based and implementation is a project rather than a signup.

Rippling

Rippling sells a unified employee record where payroll, HR, and IT provisioning share one data model. The core platform is $35 per month plus $8 per employee, with payroll as a separate module. Real-world all-in costs land between $25 and $45 per employee per month once you assemble a working configuration.

What each provider actually costs a Mississippi employer

The table below models published rates at three headcounts, plus what happens when a second state enters the picture. That last column carries more weight in Mississippi than in most states, because four state lines sit within commuting distance of the population centers.

Patriot stays cheapest at every headcount, and the gap compounds: $12 a month below SurePayroll at 10 employees and $92 below it at 50. Square runs a close second with a flat multi-state structure, which flips the ranking the moment a DeSoto County employer hires someone in Memphis. Gusto Simple is competitive until that same hire forces the Plus tier, at which point a 25-person payroll goes from $199 to $380 per month.

The subscription is also not the whole Mississippi payroll tax number, though here it is closer than usual. A 25-person employer paying an average of $45,000 owes unemployment contributions only on the first $14,000 per person, so at a 1.20 percent new employer rate the annual state unemployment cost is roughly $4,200 across the whole company. State income tax is withheld from employees rather than paid by the employer, and there is no local tax, no disability premium, and no leave contribution to add.

That is a short employer-side bill by national standards, and it gets shorter still in a state with no wage income tax at all. The reason it matters when choosing software is that the employer cost you are optimizing in Mississippi really is mostly the subscription, which is not true in states that stack leave premiums and city levies on top.

Choosing a payroll provider for Mississippi

Four questions separate providers that will work here from providers that will quietly generate notices. None of them is about local tax, because there is none.

One item sits outside the payroll engine entirely. Every Mississippi new hire needs a federal I-9 and W-4, a signed Form 89-350, direct deposit authorization, and a new hire report filed within 15 days. Those are document collection tasks that happen before the first pay run, and a payroll platform that starts at the pay run assumes they were already done.

Before you choose

FirstHR does not process payroll, file payroll taxes, move money, or administer benefits. Every provider above does something we do not.

If running payroll is the problem in front of you, one of them is the answer. What we handle is the layer that feeds payroll: onboarding workflows, e-signatures on I-9s and offer letters, and employee records for small US teams at a flat $98 to $198 per month.

Several Mississippi obligations are document problems rather than payroll problems. If the recurring issue is that Form 89-350 never got signed, the direct deposit form is missing, and nobody is sure whether the 15-day new hire report went out, that is a collection failure rather than a payroll processing failure, and HR document management is exactly the gap we built for.

Frequently Asked Questions

What is the Mississippi income tax rate for payroll withholding?

Zero percent on the first $10,000 of taxable income and 4 percent on the balance for tax year 2026, down from 4.4 percent for 2025, with 3.75 percent scheduled for 2027. There are no brackets above the $10,000 step and no local income tax anywhere in the state. Withholding comes from the wage bracket tables in Publication 89-700.

Is Form 89-350 required for new Mississippi employees?

Yes. Publication 89-700 states that federal exemption certificates will not supply the proper information for Mississippi withholding, so each employee must complete Form 89-350. An employee who files none is withheld at zero exemption, and an employee whose status changes in a way that increases withholding must file an amended certificate within ten days.

What is the Mississippi unemployment insurance wage base?

$14,000 per employee per year, stated on the MDES quarterly report Form UI-2/3. Contributions are employer-paid with nothing withheld from employees, and quarterly wage and contribution reports are due by the last day of the month following each quarter: April 30, July 31, October 31, and January 31.

What is the Mississippi unemployment tax rate for a new employer?

1.00 percent in the first year of liability, 1.10 percent in the second, and 1.20 percent in the third and subsequent years until a modified rate is assigned. Those rates exclude the Workforce Investment and Training contribution. Experience rated employers pay between 0.0 and 5.4 percent based on benefits charged, taxable wages paid, and the state experience ratio.

What is the minimum wage in Mississippi?

There is no state minimum wage, so the federal $7.25 per hour applies to covered nonexempt employees, with no indexing and no scheduled change. Mississippi Code Section 17-1-51 preempts local minimum wage ordinances, so the rate is identical statewide. Tipped employees follow the federal $2.13 cash wage with a tip credit of up to $5.12.

How often must Mississippi employers pay employees?

Only manufacturers with 50 or more employees who employ public labor, and public service corporations, are required to pay at least every two weeks or twice a month under Mississippi Code Section 71-1-35. Each payment must settle wages earned up to no more than ten days before the pay date, or fifteen days for a public service corporation. Every other employer sets frequency by policy or agreement.

When is a final paycheck due in Mississippi after a quit or a firing?

There is no state deadline, and it does not differ between a resignation and a discharge. The federal default applies, so final wages are due no later than the next regular payday for the period worked. Unused vacation or paid time off is payable only where a written policy or contract promises it.

How often does a Mississippi employer file withholding returns?

The Department of Revenue assigns monthly or quarterly frequency; employers do not choose. Returns are due the fifteenth of the month following the period, and a return is required even when nothing was withheld. Seasonal and transient employers file monthly. W-2s are due January 31 and 1099s February 28, with electronic filing mandatory at ten or more W-2s.

Does Mississippi have local payroll taxes?

No. No Mississippi city or county levies an income tax, occupational tax, or payroll tax, and there is no state disability, paid family leave, or paid sick leave contribution. The stack is federal taxes, state withholding, and unemployment contributions, which is why provider selection here turns on price and service rather than jurisdictional coverage.

How do I register a business for Mississippi payroll taxes?

Separately with each agency. Withholding registration goes through the Department of Revenue Taxpayer Access Point, and unemployment registration through the Department of Employment Security once liability is met, which for a commercial enterprise is $1,500 in wages in a quarter or one worker in 20 different calendar weeks. Workers compensation is required from the fifth employee.

How long do Mississippi employers have to report a new hire?

Fifteen days from the hire date, to the Mississippi State Directory of New Hires at the Department of Human Services, five days tighter than the federal baseline. The requirement also covers rehires, meaning anyone returning after a layoff, furlough, separation, leave without pay, or termination of at least 60 consecutive days. Electronic filers submit twice monthly, 12 to 16 days apart.

Does Mississippi require paid sick leave or disability insurance?

No. There is no state paid sick leave law, no state disability program, and no paid family leave contribution, so there is no state deduction for any of them. The federal Family and Medical Leave Act still applies at 50 or more employees, and any paid leave an employer offers voluntarily is governed by its own written policy.

Does Mississippi require workers compensation insurance?

Yes, once five or more workers are regularly employed in the same business under Mississippi Code Section 71-3-5, with nonprofit charitable, fraternal, cultural, and religious organizations excluded. Employers below the threshold may carry it voluntarily. Larger employers can apply to the Commission for an exemption from insuring by showing the financial ability to pay compensation. Failing to secure required coverage is a misdemeanor and can also draw a civil penalty of up to $10,000.

How much does payroll software cost for a Mississippi small business?

At 10 employees, published July 2026 rates run roughly $87 for Patriot Full Service, $89 for Paychex Flex Essentials, $95 for Square, $99 for SurePayroll, $109 for OnPay or Gusto Simple, and $115 for QuickBooks Core. At 50 employees the same plans land between $287 and $379. ADP RUN and Paylocity quote individually.
